	build: Update NEWS file

	build: Update SPICE_REVISION for new release
	No ABI addition/removal/... so no need to change anything else.

	smartcard: Remove duplicate accessor
	smartcard_channel_client_get_device() is the same as
	smartcard_channel_client_get_char_device(). Let's only keep the latter.

	smartcard: Fix SmartcardChannelClient creation
	The wrong type (RED_TYPE_CHANNEL_CLIENT rather than
	TYPE_SMARTCARD_CHANNEL_CLIENT) was used when creating a
	SmartcardChannelClient, which meant the _init function was never called,
	and SmartcardChannelClient::priv was never initialized.

	This caused a crash when trying to connect with --spice-smartcard to a
	VM with a smartcard channel configured.

	Fix build when builddir != srcdir
	The following build error occurs when building outside of the source
	directory:

	glib-mkenums --template spice-server-enums.tmpl.c ../../server/spice-server.h > spice-server-enums.c
	Can't open spice-server-enums.tmpl.c: No such file or directory
	Makefile:1111: recipe for target 'spice-server-enums.c' failed

	Make/Automake uses VPATH to determine that the spice-server-enums.tmpl.c
	file listed in the prerequisites for the rule is located in the srcdir.
	When we use an automatic variable (e.g. $<), the full path to the
	resolved file is used. But when we use the literal filename directly
	within the rule definition, this won't happen. So we need to explicitly
	specify that the input template file is located in srcdir.

	Remove red_pipe_add_verb family function
	These functions were implementing the same stuff as empty
	messages functions provided by RedChannel so reuse them.

	The implementation seems a bit different but the result
	is the same. Specifically:
	- RedEmptyMsgPipeItem::msg is int while RedVerbItem::verb was
	  uint16_t however this data goes into the message type which
	  is uint16_t (a 16 bit on the network protocol);
	- red_channel_client_send_empty_msg calls
	  red_channel_client_begin_send_message while red_marshall_verb
	  does not. However red_marshall_verb is called only by
	  cursor_channel_send_item and dcc_send_item which always
	  calls red_channel_client_begin_send_message.
	  Note that in dcc_send_item when an empty message is sent
	  red_channel_client_send_message_pending always returns
	  true;
	- when a PipeItem is created red_channel_client_pipe_add_empty_msg
	  calls red_channel_client_push while red_pipe_add_verb does not.
	  This actually make very little difference as this kind of item are
	  never removed from the queue and a push is forced in every case
	  running the event handler for the stream watch (see
	  prepare_pipe_add and red_channel_client_event).

	will be in all queues. The same check is done for dcc_gl_scanout_item_new.
	dcc_gl_scanout_item_new is called when Qemu calls spice_qxl_gl_draw_async.
	Technically a client can support SPICE_DISPLAY_CAP_GL_SCANOUT but server

	RedsState: clean up spice_server_char_device_add_interface
	Previously we were creating a variable named 'dev_state' and then
	apparently not using it. Well, we *were* actually using it, but in a
	convoluted sort of way. Creating a new RedCharDevice has a
	side-effect of setting itself as the 'st' attribute of
	SpiceCharDeviceInstance. So 'dev_state' and 'char_device->st' are in
	fact the same variable. But they were being used interchangeably, which
	was rather confusing. For example

	if (dev_state)
	    // do something with char_device->st

	So this patch doesn't actually change anything, but it makes the code a
	bit easier to follow.

	tests: Check setting of agent properties
	Acked-by: Frediano Ziglio <fziglio@redhat.com>

	reds: Do not crash when setting agent property
	Agent properties like file transfer or copy & paste can be disabled by
	calling spice_server_set_agent_{copypaste, file_xfer} before the spice
	server is initialized. In that case the call crashes the server because
	the agent device is created after the initialization.

	To avoid the crash this commit introduce a helper function for setting

	Acked-by: Pavel Grunt <pgrunt@redhat.com>

	Prevent possible buffer overflow in SpiceKbdState
	key and key_ext in SpiceKbdState are indexed using

	   state[scan & 0x7f]

	where scan is a 8 bit value got from client. In theory client can send
	any value causing scan & 0x7f to be 0x7f. However these arrays contains
	only 0x7f values so 0x7f cause a off one overflow.
	This potentially cause key_ext to overflow in reds pointer following.
	Happily this is not exploitable in either 32 or 64 bit environment.
	On 64 bit key_ext is followed by a 4 byte (sizeof(bool) == 4) padding
	which is written by the possible overflow.
	On 32 bit reds will be overwritten with either 0 or 1 which will cause
	a SIGSEGV leading to a DoS. Considering that you have to have access
	to the machine with a client you are just shutting down only guests you
	can access to.

	Call migrate_end_complete() after falling back to switch-host
	Eventually, during a seamless migration, qemu may finish to migrate
	before the spice client even finished to connect all channels to
	destination and informed the server. In this case,
	main_channel_client_migrate_src_complete() will fall back to
	switch-host method, and reds_mig_fill_wait_disconnect() is called to
	complete the migration (disconnecting all channels).

	reds_mig_cleanup() is called when all channels are disconnected, but
	reds->mig_wait_connect is still TRUE, and it will call
	migrate_connect_complete() instead of the expected
	migrate_end_complete(). Setting reds->mig_wait_connect to FALSE when
	reds_mig_fill_wait_disconnect() solves the issue.

	streaming: Add support for GStreamer 0.10
	configure will use GStreamer 1.0 if present and fall back to
	GStreamer 0.10 otherwise.
	ffenc_mjpeg takes its bitrate as a long so extend set_gstenc_bitrate().

	streaming: Dynamically adjust the GStreamer encoder bitrate if possible
	This is faster and lets the encoder leverage past bitrate shaping
	history to attain the target faster.

	streaming: Respect the GStreamer encoder's valid bit rate range
	GObject returns an error instead of clamping if given an out of range
	property value.

	streaming: Give up after a while if GStreamer cannot handle the video
	This typically happens when sending very small frames (less than
	16 pixels in one dimension) to the x264enc encoder.
	This avoids repeatedly wasting time rebuilding the pipeline.

	streaming: Adjust the frame rate based on the GStreamer encoding time

	streaming: Adjust the GStreamer encoder bit rate to the network
	The video encoder uses the client reports and/or notifications of
	server frame drops as its feedback mechanisms. In particular it keeps
	track of the maximum video margin and reduces the bit rate whenever the
	margin goes below certain thresholds or decreases too sharply.
	It uses these to figure out the lowest bit rate that causes negative
	feedback, and the highest bit rate that allows a return to positive
	feedbacks. It then works to narrow this range and settles on the lower
	end once the spread has gone below a given threshold.
	All the while it monitors the effective bit rate to ensure the target
	bit rate does not grow significantly beyond what the GStreamer encoder
	will produce: this avoids target bit rate 'bubbles' which would
	invariably be followed by a bit rate crash with accompanying frame loss.
	As soon as the network feedback indicates a significant degradation the
	bit rate is lowered to minimize the risk of frame loss and/or long
	freezes.
	It also relies on the existing shaping of the GStreamer output bit rate
	to minimize the pipeline reconfigurations.

	streaming: Shape the bit rate of the GStreamer codecs output
	The GStreamer codecs don't follow the specified bit rate very closely:
	they can decide to exceed it for ten seconds or more if they consider
	the scene deserves it. Such long bursts are enough to cause network
	congestion, resulting in many lost frames which cause significant
	display corruption.
	So the GStreamer video encoder now uses a short 300ms virtual buffer
	to shape the compressed video output and ensure we don't exceed the
	target bit rate for any significant length of time.
	It could instead rely on the network feedback (when available) to lower
	the bit rate. However frequent GStreamer bit rate changes lower the
	overall compression level and also result in a lower average bit rate,
	both of which result in lower video quality.
	The GStreamer video encoder also keeps track of the encoded frame size
	so it can gather statistics and call update_client_playback_delay()
	with accurate information and also annotate the client report debug
	traces with the corresponding bit rate information.

	streaming: Add h264 support to the GStreamer video encoder

	streaming: Avoid copying the input frame in the GStreamer encoder
	Note that we can only avoid copies for the first 1 Mpixels or so.
	That's because Spice splits larger frames into more chunks than we can
	fit GstMemory fragments in a GStreamer buffer. So if there are more
	pixels we will avoid copies for the first 3840 KB and copy the rest.
	Furthermore, while in practice the GStreamer encoder will only modify
	the RedDrawable refcount during the encode_frame(), in theory the
	refcount could be decremented from the GStreamer thread after
	encode_frame() returns.

	streaming: Handle and recover from GStreamer encoding errors
	If an error occurs for whatever reason (e.g. codec not supporting odd
	frame sizes), the GStreamer pipeline will drop the current buffer,
	causing the encoder to be stuck waiting for the sample. So this patch
	tracks error notifications and ensures we don't wait for a sample if
	none will come.

	streaming: Let the video encoder manage the compressed buffer
	This way the video encoder is not forced to use malloc()/free().
	This also allows more flexibility in how the video encoder manages the
	buffer which allows for a zero-copy implementation in both video
	encoders.

	streaming: Add VP8 support to the GStreamer video encoder

2016-06-14  Pavel Grunt  <pgrunt@redhat.com>

	replay: Add an option to change video codec

2016-06-14  Francois Gouget  <fgouget@codeweavers.com>

	streaming: Let the administrator pick the video encoder and codec
	The Spice server administrator can specify the encoder and codec
	preferences to optimize for CPU or bandwidth usage. Preferences are
	described in a semi-colon separated list of encoder:codec pairs.
	The server has a default preference list which can explicitly be
	selected by specifying 'auto'.

	streaming: Check the client video codec capabilities
	The server picks a codec supported by the client based on the following
	new client capabilities:
	 * SPICE_DISPLAY_CAP_MULTI_CODEC which denotes a recent client that
	   supports multiple codecs. This capability is needed to not have to
	   hardcode that MJPEG is supported. This makes it possible to write
	   clients that don't support MJPEG.
	 * SPICE_DISPLAY_CAP_CODEC_XXX, where XXX is a supported codec. Note
	   that for now the server only supports the MJPEG codec.

	streaming: Add a GStreamer 1.0 MJPEG video encoder and use it by default
	This introduces a pared down GStreamer-based video encoder to serve as
	the basis for later enhancements.
	In this form the new encoder supports both regular and sized streams
	but lacks any rate control. It should still work fine if bandwidth is
	sufficient such as on LANs.

	streaming: Remove the width/height encode_frame() parameters
	encode_frame() needs the QXL_DRAW_COPY operation's SpiceCopy.src_area
	field anyway, so the width and height parameters were redundant.

	mjpeg: Use src_area as the authoritative source for the frame dimensions
	Video frames correspond to QXL_DRAW_COPY operations where the frame area
	is defined by the SpiceCopy.src_area field.

	streaming: Simplify is_next_stream_frame()
	After the removal of Drawable::sized_stream, we no longer need to detect
	if the stream changes size in is_next_stream_frame() so it can return a
	boolean rather than a value from an enum.

	streaming: Remove unused detach_stream() argument
	After the removal of Drawable::sized_stream, the last argument to
	detach_stream() is no longer used.

	streaming: Remove the Drawable.sized_stream field
	Only red_marshall_stream_data() needs to know whether to send the frame
	using a SpiceMsgDisplayStreamDataSized or a regular StreamData message.
	So check whether we have a sized frame there and simplify the rest of
	the code.

	streaming: Rework red_marshall_stream_data a bit
	This code just refactors the function without doing any functional
	changes. The actual changes will be in the next commit, and this will
	make the next commit much more obvious.

	streaming: Better check for sized frames
	Usually the RedDrawable bbox dimensions match the src_area dimensions
	so that checking that the bbox matches the stream's original dest_area
	should be enough to determine if sized stream support is needed to
	send the frame.
	But making the bbox different could be used to have the scaling be
	performed on the client side. So it's better not to assume the bbox and
	src_area have the same dimensions.

	command although the command is parsed using g_shell_parse_argv

	One easy way to use it is to just use a compressor like gzip with

	  export SPICE_WORKER_RECORD_FILENAME=/tmp/qemu_record.gz
	  export SPICE_WORKER_RECORD_FILTER=gzip
	  qemu ...

	The filter will receive the recording on standard input and is

	Following commit e8017dd366afabbd099a13d7d455a37fd50be124 here
	are some more ifdef simplification.

	For PIXEL_ID and PIXEL_DIST macros,
	the ifndef LZ_PLT defines are special cases of the LZ_PLT
	(#else) defines, when pix_per_byte is 1

	Now do_match can accept pix_per_byte param for all different
	definitions (implementations).

	Add red_client_seamless_migration_done_for_channel()
	This is a public RedClient API that handles updating itself rather than
	having the RedChannelClient poke around at the internal structure in
	rec_channel_client_seamless_migration_done().

	Simplify DisplayChannel hold_item()
	Since all pipe items implement refcounting now, just call
	red_pipe_item_ref() and eliminate the switch statement.

	Remove unnecessary cursor_pipe_item_ref()
	Use the base red_pipe_item_ref() instead of adding an additional static
	wrapper function.

	make spice-server-replay use dynamic spice-server library
	spice-server-replay is built with the same settings as tests.
	Currently the tests links to a convenience spice-server library.
	A convenience library is a static library build with object file
	for a dynamic library.
	This make all tests contain all spice-server library code and not
	linking to the spice-server dynamic library (the .so).
	It's not a problem for most tests however this make impossible for
	spice-server-replay utility to be used with a dynamic spice-server
	library (you have to recompile it including the library).
	This is a pity as you could for instance compare your system
	library behavior with the library you are developing.
	Also if we decide to install in a future the utility for testing
	we would have lot of code duplication.

	remove a warning building a test
	With my compile switches (which are mostly derived from RedHat spec
	file) I'm getting this warning:

	stream-test.c: In function 'sock_fd_read':
	stream-test.c:66:43: warning: dereferencing type-punned pointer will
	break strict-aliasing rules [-Wstrict-aliasing]

	                                           ^

	memcpy could decrease performance but as this is a test it's not
	an issue.

	better to do everything in one go in reds.c, and call that single method

	Fix dcc_start() regression
	Commit e9ed125d introduced a dead-lock regression by taking twice the
	same lock recursively. The previous code checked if a dmabuf was set
	without taking the lock, for queuing scanout messages. Since the message
	is being processed later on, it make sense to queue and delay until it
	is sent to check if there is a scanout.

	Remove global 'dispatchers', 'num_active_workers' variables
	Since these are server-level variables, move them into RedsState.
	However, num_active_workers was removed because:
	- each dispatcher always has 1 active worker, so we can determine the
	  number of active workers by counting the dispatchers
	- it was never actually set correctly. Even if there was more than one
	  worker, this variable was always only set to either 0 or 1.

	In red_channel_client_cancel_ping_timer latency timer is cancelled and

	Handle GL_DRAW_DONE
	When a client is done with drawing and sends
	SPICE_MSGC_DISPLAY_GL_DRAW_DONE, or when it ends, update the number of
	async counts.

	[reduce critical message to a warning; do not reset gl_draw_ongoing
	 - Frediano Ziglio]

	Handle GL_DRAW messages
	Create an async, and marshall the GL_DRAW message. Count number of
	clients, and wait until gl_draw_async_count is 0 to complete the async.
	The count is going to be updated in the following patch when the client
	is done with the draw.

	[removed unused sent field; move gl_draw_async_count to DisplayChannel
	 - Frediano Ziglio]

	Send current GL scanout to new client

	Handle GL_SCANOUT messages
	Go through dispatcher and marshall scanout message. Since the marshaller
	and the QXL state are manipulated from different threads, add a mutex to
	protect the current scanout.

	Add new spice-gl stubs API
	- spice_qxl_gl_scanout() to take the current scanout

	- spice_qxl_gl_draw_async() to draw the scanout, is like other Spice async
	  functions, it takes a cookie and will return in the
	  QXLInterface.async_complete()

	Two new fields are also added to QXLState, in order to save the current
	scanout, and the pending async.

	A scanout can't be updated if there are pending draw atm. Discarding
	outdated draws is left as a future improvement to allow updating the
	scanout without waiting for draw async to be done.

	This reduce cpu usage if guests are mainly idle.
	If you consider 100 guests waiting to login with cursor blinking
	and considering the polling was done 200 times every 10ms (maximum)
	just the cursor blinking was causing 10100 loop iterations per second
	while now only 200 are needed (considering cursor blinking every

	worker: avoid blocking loop
	Make sure we process commands after we can send data to client.
	If during processing we detected that there was too much data in the
	clients queues the processing of commands just stop till the next
	iteration.
	However if all data are pushed in a single iteration of the loop
	and commands were already processed there was the (remote) possibility
	that the loop hangs till a separate event (like a screen resize on
	client window) arrive.
	I manage to reproduce and after half an hour no events arrived.
	This patch detect that processing was stuck and now we can process new
	commands and force a new iteration.

	replay: remove a message that could be caused by a race condition
	The req_cmd_notification callback is called by spice-server when it
	has processed all commands and wants to be notified (by a wakeup) that
	new commands have been appended to the command queue.
	Replay utility tries to fill the commands when it detects that
	spice-server is trying to read commands but there are no more commands.
	However, new commands are appended in a separate thread so if the main
	red worker loop on spice-server is really tight this request can
	happen.
	Avoid printing any message on this condition, message will be appended
	and loop woken up when replay code can do it.

	worker: push data when clients can receive them
	During every iteration of the main worker loop, outgoing data was pushed to
	the client. However, there was no guarantee that the loop would be woken up
	in every situation. So there were some conditions where the loop would stop
	iterating until a new event was sent.

	Currently, the events that can wake up the main worker loop include:
	 - data from dispatcher (including wakeups from the guest)
	 - data from clients
	 - timeouts on a stream
	 - other timeouts
	 - polling

	This patch adds a new wakeup event: when we have items that are queued to
	be sent to a client, we set up a watch event for writing data to the
	client. If no items are waiting to be sent, this watch will be disabled.
	This allows us to remove the explicit push from the main worker loop.

	This has some advantages:
	 - it could lower latency as we don't have to wait for a polling timeout.
	   From my experiments using a tight loop (so not really the ideal
	   condition to see the improvements) the total time was reduced by 2-3%)
	 - helps reduce the possibility of hanging loops
	 - avoids having to scan all clients to detect which one can accept data.

	Remove compress_buf_new
	This commit reworks a bit the management of RedCompressBuf so that
	compress_buf_new/compress_buf_free become unneeded.
	Since d25d6ca0 and the introduction of encoder_data_reset,
	compress_buf_free is already unused outside of dcc-encoders.c and could
	be static. This in turn makes compress_buf_new a bit odd as the matching
	destructor is never used in dcc.c.
	This commit introduces an encoder_data_init() method which is hiding
	the initialization of the EncoderData structure from the dcc.c code,
	allowing to get rid of compress_buf_new() calls from dcc.c code.

	It also uses this as an opportunity to stop using GSlice for
	RedCompressBuf.

	Update NEWS for 0.13.0 release

	spicevmc: Drop unsent data on client disconnection
	When redirecting a USB webcam over a slow link, it's currently possible
	to hit an assertion in spice-server by running cheese (application using
	the webcam), killing the client with ctrl+c and then restarting the
	client:
	qemu-kvm: spicevmc.c:324: spicevmc_red_channel_alloc_msg_rcv_buf:
	Assertion `!state->recv_from_client_buf' failed.

	This happens when red_peer_handle_incoming tries to allocate memory for
	a message using spicevmc:
	handler->msg = handler->cb->alloc_msg_buf(handler->opaque, msg_type,
	msg_size);

	red_peer_handle_incoming() is called when there is client data to be
	read, and does
	- call alloc_msg_buf() to allocate memory for the message
	- read the message
	- if the read was partial, return early, the main loop will call again
	  red_peer_handle_incoming() when there is more data available for that
	  channel
	- parse the message
	- call release_msg_buf() to free the message

	For channels based on spicevmc (usbredir and port), alloc_msg_buf()
	stores message data in SpiceVmcState::recv_from_client_buf and before
	allocating new memory, it asserts that it's NULL.

	This is what causes this crash in the following scenario:
	- SpiceVmc::alloc_msg_buf() is called and allocates memory for a new
	  message in SpiceVmcState::recv_from_client_buf
	- red_peer_handle_incoming() returns early as all the spicevmc message
	  data hasn't been received yet
	- the client gets killed
	- the main channel notices the disconnect and calls
	  main_dispatcher_client_disconnect() which will disconnect all the
	  channels
	- SpiceVmc::on_disconnect is called
	- after the new client connects, SpiceVmc::alloc_msg_buf() is called,
	  notices that SpiceVmcState::recv_from_client_buf is already set, and
	  asserts()

	This commit makes sure the partial SpiceVmcState::recv_from_client_buf
	data is cleared on disconnect so that the assert does not trigger.

	This fixes https://bugzilla.redhat.com/show_bug.cgi?id=1264113

	channel: add option tcp keepalive timeout to channels

2016-01-12  Christophe Fergeau  <cfergeau@redhat.com>

	stat: Make stat_compress_init/stat_init the same
	When COMPRESS_STAT is not set, and RED_WORKER_STAT is set,
	stat_time() will be a no-op, but stat_start_time_init() will try to use
	stat_info_t::clock. This causes a compile warning on 32 bit arches (not
	sure why not on 64 bit builds), as well as an error from valgrind.

	Since stat_time() and stat_compress_time() are both doing the same work,
	this commit makes them the same function, which ensures
	stat_info_t::clock will be set and stat_start_time_init() can be used
	regardless of the _init() method which is called.

	channel: use iface parameter to distinguish interface context
	Now we can use the iface parameter to distinguish the context instead
	of doing strange assumption on opaque and its state.

	Acked-by: Christophe Fergeau <cfergeau@redhat.com>

	channel: add interface parameters to SpiceCoreInterfaceInternal
	This patch and previous ones want to solve the problem of not having a
	context in SpiceCoreInterface. SpiceCoreInterface defines a set of
	callbacks to handle events in spice-server. These callbacks allow to
	handle timers, watch for file descriptors and send channel events.
	All these callbacks do not accept a context (usually in C passed as a
	void* parameter) so it is hard for them to differentiate the interface
	specified.
	Unfortunately this structure is used even internally from different
	contexts for instance every RedWorker thread has a different context. To
	solve this issue some workarounds are used. Currently for timers a variable
	depending on the current thread is used while for watches the opaque
	parameter to pass to the event callback is used as it currently points just
	to RedChannelClient structure.  This however imposes some implicit
	maintainance problem in the future. What happens for instance if for some
	reason a timer is registered during worker initialization, run in another
	thread? What if we decide to register a file descriptor callback for
	something not a RedChannelClient?  Could be that the program will run
	without any issue till some bytes change and weird things could happen.

	The implementation of this solution is done implementing an internal "core"
	interface that has context specific and use it to differentiate the
	context instead of relying on some other, hard to maintain, detail. Then an
	adapter structure (name inpired to the adapter pattern) will provide the
	internal core interface using the external, public, definition (in the
	future this technique can be used to extend the external interface without
	breaking the ABI).

	Acked-by: Christophe Fergeau <cfergeau@redhat.com>

	display: make get_drawable symmetric to display_channel_drawable_unref
	Make possible to safely call display_channel_drawable_unref straight
	after calling get_drawable.

	Problem was function definitions and dependency.

	display_channel_drawable_try_new is supposed to return an uninitialized
	pointer (or NULL on failure) to a Drawable structure.

	(display_channel_)get_drawable is supposed to return an initialized
	pointer (or NULL) to a Drawable structure.

	(display_channel_)add_drawable is supposed to add the Drawable to the
	list/tree of drawing to draw.

	Now, with these definitions after get_drawable the Drawable state (if
	pointer is not NULL) should be consistent and we should be able to call
	display_channel_drawable_unref.

	In the current code this was not true as for instance surface_id was
	copied to Drawable but the reference counter of the surface was not
	incremented leading possible unref call to decrement the counter and
	free the surface. This can happen if any call between get_drawable and
	unref does not increment the reference in a consistent way. This
	basically means that every present or future code in the path between
	get_drawable and unref have to know this unconsistency and handle it.
	This is a maintaining problem as people need to know these details when
	editing existing code (actually this is display_channel_add_drawable
	code).
	This basically create a dependency between get_drawable and
	add_drawable.

	spicevmc: set state of DeviceInstance to NULL
	After spice_char_device_state_destroy is called spicevmc should not keep
	reference to that memory. state->chardev_st and sin->st point to the
	same SpiceCharDeviceState and both should be set to NULL when it is
	destroyed.

	char-device: set to NULL freed pointers on destroy
	As SpiceCharDeviceState is only unref'ed on
	spice_char_device_state_destroy the same device could be destroyed more
	then once so the pointers that are freed should be set to NULL.

	char-device: free all memory pool when no clients
	When no client is connect we should not need to keep the memory pool
	used by char-device. In most situations this is not significant but
	when using webdav this could mean freeing MAX_POOL_SIZE bytes

	Related: https://bugs.freedesktop.org/show_bug.cgi?id=91350

	char-device: Define a memory pool limit
	Otherwise the amount of unused memory could grow while transfering big
	chunks of data. This change only means that once the memory was used it
	will not be stored again after the limit was reached.

	char-device: fix usage of free/unref on WriteBuffer
	There are places were the could should definetly free the

	This patch creates the spice_char_device_write_buffer_unref and properly

	This didn't cause any problems because SPICE_MSG_CURSOR_INVAL_ONE and

	Prevent DoS from guest trying to allocate too much data on host for chunks
	Limit number of chunks to a given amount to avoid guest trying to
	allocate too much memory. Using circular or nested chunks lists
	guest could try to allocate huge amounts of memory.
	Considering the list can be infinite and guest can change data this
	also prevents strange security attacks from guest.

	Prevent memory leak if red_get_data_chunks_ptr fails

	Acked-by: Christophe Fergeau <cfergeau@redhat.com>

	Fix race condition in red_get_data_chunks_ptr
	Do not read multiple times data from guest as this can be changed by
	other guest vcpus. This causes races and security problems if these
	data are used for buffer allocation or checks.

	Actually, the 'data' member can't change during read as it is just a
	pointer to a fixed array contained in qxl. However, this change will
	make it clear that there can be no race condition.

	Fix integer overflow computing glyph_size in red_get_string
	If bpp is int the formula can lead to weird overflows. width and height
	are uint16_t so the formula is:

	  size_t = u16 * (u16 * int + const_int) / const_int;

	so it became

	  size_t = (int) u16 * ((int) u16 * int + const_int) / const_int;

	However the (int) u16 * (int) u16 can then became negative to overflow.
	Under 64 bit architectures size_t is 64 and int usually 32 so converting
	this negative 32 bit number to a unsigned 64 bit lead to a very big
	number as the signed is extended and then converted to unsigned.
	Using unsigned arithmetic prevent extending the sign.

	Fix some integer overflow causing large memory allocations
	Prevent integer overflow when computing image sizes.
	Image index computations are done using 32 bit so this can cause easily
	security issues. MAX_DATA_CHUNK is larger than the virtual
	card limit, so this is not going to cause change in behaviours.
	Comparing size calculation results with MAX_DATA_CHUNK will allow us to
	catch overflows.
	Prevent guest from allocating large amount of memory.

	Define a constant to limit data from guest.
	This limit will prevent guest trying to do nasty things and DoS to host.

	improve performances comparing image pixels
	This patch contains a bit of small optimizations.
	It avoid boolean	 operations which could involve branches replacing
	with binary operations (equal/all_ident -> some_differences).
	The other optimization avoids the use of ABS. First the way the macro
	was used (with a large expression) was not easy to optimize by the
	compiler.
	Then instead of using ABS a much simpler range check is used so instead
	of (ABS(n) >= k) a ((n) <= -k || (n) >= k) is used. This looks small
	but modern compilers can translate this not in range check in a couple
	of machine instructions (and a single compare).

	Since commit ab12cf414c, these 2 version numbers can no longer be out of

	Commit 3c6b4e41 removed spice-experimental.h as this header was not

	(without using any of its symbols) until commit v2.3.0-rc0~135^2~1

	As this is fairly recent (Nov 2014), building older QEMUs with new
	spice-server releases, or even bisecting QEMU will be broken as they
	will be looking for a no-longer available header.

	This commit readds a spice-experimental.h file, however it only contains

	will run the commands from cmdfile ignoring timestamps, right after a

	on end of cmdfile, and exit itself after waiting for the client.

	spicy-stats from spice-gtk is useful for testing, it prints the summary
	of the traffic on each channel.

	You can also run with no client by doing:
	spice-server-replay <cmdfile>

	For example, the 300 MB file (compressed to 4 MB with xz -9) available
	at [1] produces the following output:

	spicy-stats total bytes read:

	inputs: 214

	  xzcat | server/tests/spice-server-replay -p 12345 -c `which spicy-stats` -

	Known Problems:
	* Implementation is wrong. Should do a single device->host conversion
	 (i.e. get_virt), and then marshall/demarshall that (i.e. RedDrawable).
	* segfault on file read done resulting in the above spicy-stats not
	 being reproducable (well, up to 1% yes).

	server/red_worker: record to SPICE_WORKER_RECORD_FILENAME
	if the environment variable in the title is set and can be
	opened for writing a log of all display commands (no cursor
	commands yet) and any QXLWorker calls (particularily primary
	create and destroy) will be logged to that file, and possible
	to replay using the replay utility introduced later.

	For an example file (4 MB download, 300 MB after unpack with xz,
	these 300 MB are themselves reduced from 1.2GB using zlib compression
	for any chunk):

	(old file without a header)

	server/red_{record, replay}.[ch]: introduce
	Currently hand crafted with some sed scripts and alot of vim macros from
	red_parse_qxl after considering the logger in qemu/hw/qxl-logger.c and seeing
	it was incomplete. The only problem with logging from the server and
	not from qemu is that it requires coordinated shutdown to avoid half a message.

	Should be automatically generated from a declarative syntax, i.e. qxl.proto.

	Note: zlib compression is introduced in a disabled state, see ZLIB
	define

	Now with a simple versioned header and generated ids by the server
	instead of based on the recorded file, and doesn't use more then 1024
	surfaces (configurable).

	mjpeg and jpeg encoder: fix alignment warnings
	As the input line could be uint8_t*, uint16_t* or uint32_t*, changing
	the default from uint8_t* to void* seems the correct choice to deal with
	upcasting warnings.

	Regarding chunks->data allocation, I quote Frediano explantion:
	"Lines came from spice_bitmap_get_line. This function assume that bitmap
	data is split among chunks each containing some lines
	(always full lines). If chunk->data is allocated using malloc or similar
	SHOULD (not 100% sure) be 4 bytes aligned so in our cases
	(8, 16, 24 or 32 bit images) should be aligned enough.

	All the casts unfortunately came from the fact we compute based on
	pixel bytes to make it generic so we use uint8_t*."

	and

	"Looking at code looks like these chunks came from the virtual machine.
	So the question is... why should the virtual machine give use some
	not-pixel align data?
	I would put a large comment to state that we assume VM send aligned
	data, would be stupid for the VM to not align it!"

	Lock the pixmap image cache for the entire fill_bits call
	Locking the individual calls that access the pixmap cache in fill_bits is
	not adequately thread safe.  Often a windows guest with multiple monitors
	will be sending the same image via different threads.  Both threads can
	be in fill_bits at the same time making changes to the cache for the same
	image.  This can result in images being deleted before all the client
	channels are finished with them or with the same image being send multiple
	times.  Here's what can happen with out the lock in fill_bits

	On the server in red_worker.c:fill_bits
	 Thread 1 calls pixmap_cache_hit for Image A and finds it isn't in cache
	 Thread 2 calls pixmap_cache_hit for Image A and finds it isn't in cache

	 Thread 1 adds Image 1 to pixmap_cache (1x)
	 Thread 2 adds Image 1 to pixmap_cache (2x)

	On the client
	 Channel 1 adds Image A to image_cache (1x)
	 Channel 2 replaces Image A in image_cache (1x)

	On server
	 Thread 1 sends Image A rendering commands
	 Thread N removes Image A from pixmap_cache (image remains - 1x)
	 Thread 2 sends Image A rendering commands

	On client
	 Channe1 renders from Image A
	 Channel N removes Image a from image_cache (image is completely removed)
	 Channel2 render command hangs waiting for Image A

	server: allows to set maximum monitors

	reds: increase listening socket backlog
	With a TCP socket, the backlog doesn't seem to matter much,
	perhaps because of latency or underlying protocol behaviour. However,
	on UNIX socket, it is fairly easy to reach the backlog limit and the
	client will get an EAGAIN error (but not ECONNREFUSED as stated in
	listen(7)) that is not easy to deal with: attempting to reconnect in a
	loop might busy-loop forever as there are no guarantee the server will
	accept new connections, so it will be inherently racy.

	Typically, Spice server can easily have up to 15 concurrent incoming
	connections that are established during initialization of the session.
	To improve the situation, raise the backlog limit to the default maximum
	system value, which is 128 on Linux.

	LZ4: Send the original format with the compressed data

	LZ4: Do not reverse bottom-up images
	Reversing the bottom-up images in the server is not needed since Pixman,
	in the client, is able to deal with them. As a result, the previous code
	was more complex and wrong. This commit fixes and cleans it.

	LZ4: Fix encoder output size

	LZ4: Limit LZ4 to RGB formats
	Currently, the LZ4 encoding only (partially) supports RGB images, so
	we must check the image format before using it. In the future, indexed
	formats may be implemented too, but their use is usually very small
	compared to RGB.

	This function is not related to migration.

	Rename mm_timer/mm_time
	As suggested by Christophe on the mailing list.

	Remove guest side video time-stamping
	The multimedia time is defined by the server side monotonic time [1],
	but the drawing time-stamp is done in guest side, so it requires
	synchronization between host and guest. This is expensive, when no audio
	is playing, there is a ~30x/sec wakeup to update the qxl device mmtime,
	and it requires marking dirty the rom region.

	Instead, the video timestamping can be done more efficiently on server
	side, without visible drawbacks.

	[1] a better timestamp could be the audio time, since audio players are
	    usually sync with audio time)

	Don't set SpiceLinkReply::pub_key if client advertises SASL cap
	If the client advertises the SASL cap, it means it guarantees it will be
	able to use SASL if the server supports, and that it does not need a valid
	SpiceLinkReply::pub_key field when using SASL.

	When the client cap is set, we thus don't need to create a RSA public key
	if SASL is enabled server side.

	The reason for needing client guarantees about not looking at the pub_key
	field is that its presence and size is hardcoded in the protocol, but in
	some hardened setups (using fips mode), generating a RSA 1024 bit key as
	expected is forbidden and fails. With this new capability, the server
	knows the client will be able to handle SASL if needed, and can skip
	the generation of the key altogether. This means that on the setups
	described above, SASL authentication has to be used.

	Introduce red_link_info_test_capability()
	This just hides a bit of pointer arithmetic away from reds_send_link_ack.
	This helper will be used in the next commits.

	Add const to test_capability first argument
	We don't modify the capabilities content, so it can be marked as const.

2014-10-14  Uri Lublin  <uril@redhat.com>

	migration: Don't assert() if MIGRATE_DATA comes before attaching the agent
	During seamless migration, after switching host, if a client was connected
	during the migration, it will have data to send back to the new
	qemu/spice-server instance. This is handled through MIGRATE_DATA messages.
	SPICE char devices use such MIGRATE_DATA messages to restore their state.

	However, the MIGRATE_DATA message can arrive any time after the new qemu
	instance has started, this can happen before or after the SPICE char
	devices have been created. In order to handle this, if the migrate data
	arrives early, it's stored in reds->agent_state.mig_data, and
	attach_to_red_agent() will restore the agent state as appropriate.

	Unfortunately this does not work as expected, for main
	channel (agent messages).
	If attach_to_red_agent() is called before the MIGRATE_DATA
	message reaches the server, all goes well,
	but if MIGRATE_DATA reaches the server before
	attach_to_red_agent() gets called, then some assert() gets
	triggered in spice_char_device_state_restore():

	((null):32507): Spice-ERROR **: char_device.c:937:spice_char_device_state_restore: assertion `dev->num_clients == 1 && dev->wait_for_migrate_data' failed
	Thread 3 (Thread 0x7f406b543700 (LWP 32543)):
	Thread 2 (Thread 0x7f40697ff700 (LWP 32586)):
	Thread 1 (Thread 0x7f4079b45a40 (LWP 32507)):

	When restoring state, a client must already be added to the
	spice-char-device.
	What happens is that a client is not being added to the char-device
	when when MIGRATE_DATA arrives first, which leaves both
	dev->num_clients and dev->wait_for_migrate_data value at 0.

	This commit changes the logic in spice_server_char_device_add_interface(),
	such that if there is migrate data pending in reds->agent_state.mig_data
	but no client was added to the spice-char-device yet,
	then first the client is added to the device by calling
	spice_char_device_client_add(), and only then the state is restored.

	=== How to Reproduce
	To reproduce, add delays to the migration connection between
	qmeu-kvm on the source host (SRC) and on the destination (DST).

	Specifically I added a man in the middle DLY host between
	migration ports from SRC to DST.

	+-----+    +-----+     +-----+
	| SRC |--> | DLY | --> | DST |
	+-----+    +-----+     +-----+

	DLY listens on port P1 (e.g. 4444) and DST listens on port
	PINCOMING (e.g. 4444, from qemu-kvm '-incoming' command line option)

	Precondition: make sure port P1 on DLY is accessible in iptables.
	Option 1: use ssh tcp port forwarding
	On DLY host run ssh:
	  ssh DLY:P1:DST:PINCOMING DST
	Then use the following migration command (on qemu-kvm monitor):
	  client_migrate_info spice DST PSPICE
	  migrate -d tcp:DLY:P1

	Option 2: Use a simple proxy program that forwards
	packets from SRC to DST while adding some delays.
	The program runs on DLY, listens to port D1, upon
	accept connects to DST:PINCOMING and forward all
	packets from DLY:D1 to DST:PINCOMING.
	Then use the same migrate command as in option 1:
	  client_migrate_info spice DST PSPICE
	  migrate -d tcp:DLY:P1

	1. when it's a version of QEMU with this commit, but we are compiling
	   against older spice-server headers (before Opus support was added)
	2. when it's a version of QEMU without commit 795ca114d35 which added
	   what is needed for Opus support

	When we are in the second situation, having 48000 in the public header
	will actually cause issues as spice-server will know QEMU does not
	support Opus, so internally spice-server will be using a 44100 rate for
	audio. However, QEMU will be using SPICE_INTERFACE_.*_FREQ and think it
	should use a 48000 rate, which will cause distorsions as experienced in
	bug https://bugzilla.redhat.com/show_bug.cgi?id=1129961

	Reverting these constants back to 44100 will fix audio in the 'new
	spice-server/old QEMU' scenario, and won't cause issues either when both
	support Opus as in this case these constants are not used.

	Fix submodule reference

	Add missing buffer (re)allocation to reds_sasl_handle_auth_steplen()
	We need to make sure we have a buffer big enough to accomodate the data
	sent by the coming SASL step.

	Call correct SASL helper in reds_handle_auth_sasl_step
	sasl_handle_auth_start() was called instead of reds_sasl_handle_auth_step()

	Add G_GNUC_UNUSED annotations to async_read_handler args
	2 of the arguments are not used, the G_GNUC_UNUSED annotation will make
	this explicit.

	Make struct AsyncRead/async_read_handler private
	All users are now contained in reds_stream.c

	Remove RedLinkInfo::async_read
	9feed69 moved the async reader code to RedsStream so that it can be used
	for the SASL authentication code. In particular, it introduced a
	RedsStream::async_read member which is used by the SASL authentication code
	for its async operations.

	However, what was not done is to remove the now redundant
	RedLinkInfo::async_read field. This causes failures when using SASL
	authentication as the async read error callback is getting set
	on the RedLinkInfo::async_read structure, but then the SASL code is trying
	to use the RedeStream::async_read structure for its async IOs, which do not
	have the needed error callback set.

	This commit makes use of the newly introduced reds_stream_async_read()
	helper in order to make use of RedsStream::async_read.

	Call AsyncRead variables 'async' instead of 'obj'
	This is a more explicit name.

	Add reds_stream_set_async_error_handler() helper
	This replaces async_read_set_error_handler() which was unused. This sets a
	callback to be called when an async operation fails.

	We could pass the error_handler to each reds_stream_async_read() call, but as
	we will be using the same one for all async calls, it's more convenient to set it
	once and for all.
	AsyncRead is going to be private to reds_stream.c in one of the next
	commits, and the error handler will need to be set from reds.c,
	hence the move to a public RedsStream method.

	Introduce reds_stream_async_read() helper
	This will allow to make RedsStream::async_read private

	build-sys: Fix VPATH builds

	Fix --without-sasl build

	Don't truncate large 'now' values in _spice_timer_set
	static void _spice_timer_set(SpiceTimer *timer, uint32_t ms, uint32_t now)

	The _spice_timer_set() function takes a 32-bit integer for the "now" value.
	The now value passed in however, can exceed 2^32 (it's in ms and derived
	from CLOCK_MONOTONIC, which will wrap around a 32-bit integer in around 46
	days).

	If the now value passed in exceeds 2^32, this will mean timers are inserted
	into the active list with expiry values before the current time, they will
	immediately trigger, and (if they don't make themselves inactive) be
	reinserted still before the current time.

	This leads to an infinite loop in spice_timer_queue_cb().

	Introduce reds_stream_is_ssl()

	Add RedsStream::priv
	The private data is allocated at the same time as RedsStream and
	goes immediatly after the main RedsStream data.
	This private member will allow to hide internal RedsStream
	implementation details from the rest of spice-server.

	Move SASL authentication to reds_stream.h
	SASL authentication mostly use members from RedsStream to do its work, so
	it makes sense to have its code in reds_stream.c. This should allow to make
	RedsStream::sasl private in the future.

	Move async code to RedsStream
	The AsyncRead structure in reds.h wraps an async read + callback to
	be done on a stream. Moving it to reds_stream.h is needed in order
	to move SASL authentication there.

	Move stream read/write callbacks to reds_stream.c
	Now that stream creation and SSL enabling are done by helpers
	in reds_stream.c, we can move the initialization of the vfunc
	read/write pointers there too.

	Introduce reds_stream_new() helper
	Initializing a new stream means initializing quite a few fields.

	Use TLS version 1.0 or better
	When creating a TLS socket, both spice-server and spice-gtk currently
	call SSL_CTX_new(TLSv1_method()). The TLSv1_method() function set the
	protocol version to TLS 1.0 exclusively. The correct way to support
	multiple protocol versions is to call SSLv23_method() in spite of its
	scary name. This method will enable all SSL/TLS protocol versions. The
	protocol suite may be further narrowed down by setting respective
	SSL_OP_NO_<version_code> options of SSL context.  This possibility is
	used in this patch in order to block use of SSLv3 that is enabled by
	default in openssl for client sockets as of now but spice has never used

2013-10-30  Christophe Fergeau  <cfergeau@redhat.com>

	Fix buffer overflow when decrypting client SPICE ticket
	reds_handle_ticket uses a fixed size 'password' buffer for the decrypted
	password whose size is SPICE_MAX_PASSWORD_LENGTH. However,
	RSA_private_decrypt which we call for the decryption expects the
	destination buffer to be at least RSA_size(link->tiTicketing.rsa)
	bytes long. On my spice-server build, SPICE_MAX_PASSWORD_LENGTH
	is 60 while RSA_size() is 128, so we end up overflowing 'password'
	when using long passwords (this was reproduced using the string:
	'fullscreen=1proxy=#enter proxy here; e.g spice_proxy = http://[proxy]:[port]'
	as a password).

	When the overflow occurs, QEMU dies with:
	*** stack smashing detected ***: qemu-system-x86_64 terminated

	This commit ensures we use a corectly sized 'password' buffer,
	and that it's correctly nul-terminated so that we can use strcmp
	instead of strncmp. To keep using strncmp, we'd need to figure out
	which one of 'password' and 'taTicket.password' is the smaller buffer,
	and use that size.

	This fixes rhbz#999839

	think anyone uses that code. It's not tested upstream nor in fedora,
	so let's remove it.

	Silence gcc false positive with -Wuninitialized
	Some versions of gcc warn about:
	red_channel.c: In function 'red_channel_client_wait_outgoing_item':
	red_channel.c:2331: error: 'end_time' may be used uninitialized in this function [-Wuninitialized]
	red_channel.c: In function 'red_channel_client_wait_pipe_item_sent':
	red_channel.c:2363: error: 'end_time' may be used uninitialized in this function [-Wuninitialized]
	red_channel.c: In function 'red_channel_wait_all_sent':
	red_channel.c:2401: error: 'end_time' may be used uninitialized in this function [-Wuninitialized]

	This is a false positive as end_time is unitialized when timeout is -1, and
	we will only try to use end_time if timeout is not -1.

	This commit initializes end_time to UINT64_MAX to avoid that warning. As
	the test involving end_time will never be reached, we ensure it's always
	TRUE so that it would be a noop even if it was reached.

	not able to tell whether one or the other is actually faulty. It's a
	strong indication though of which operations are incorrect.

	Ideally, all operations should be checked, however, a few of them are

	red_worker: disconnect the channel instead of shutdown in case of a blocking method failure
	rhbz#1004443

	The methods that trigger waitings on the client pipe require that
	the waiting will succeed in order to continue, or otherwise, that
	all the living pipe items will be released (e.g., when
	we must destroy a surface, we need that all its related pipe items will
	be released). Shutdown of the socket will eventually trigger
	red_channel_client_disconnect (*), which will empty the pipe. However,
	if the blocking method failed, we need to empty the pipe synchronously.
	It is not safe(**) to call red_channel_client_disconnect from ChannelCbs
	, but all the blocking calls in red_worker are done from callbacks that
	are triggered from the device.
	To summarize, calling red_channel_client_disconnect instead of calling
	red_channel_client_shutdown will immediately release all the pipe items that are
	held by the channel client (by calling red_channel_client_pipe_clear).
	If red_clear_surface_drawables_from_pipe timeouts,
	red_channel_client_disconnect will make sure that the surface we wish to
	release is not referenced by any pipe-item.

	(*) After a shutdown of a socket, we expect that later, when
	red_peer_handle_incoming is called, it will encounter a socket
	error and will call the channel's on_error callback which calls
	red_channel_client_disconnect.

	(**) I believe it was not safe before commit 2d2121a17038bc0 (before adding ref
	count to ChannelClient). However, I think it might still be unsafe, because
	red_channel_client_disconnect sets rcc->stream to NULL, and rcc->stream
	may be referred later inside a red_channel_client method unsafely. So instead
	of checking if (stream != NULL) after calling callbacks, we try to avoid
	calling red_channel_client_disconnect from callbacks.

	red_channel: cleanup of red_channel_client blocking methods
	(1) receive timeout as a parameter.
	(2) add a return value and pass the handling
	    of failures to the calling routine.

	red_worker: cleanup red_clear_surface_drawables_from_pipes
	(1) merge 'force' and 'wait_for_outgoing_item' to one parameter.
	    'wait_for_outgoing_item' is a derivative of 'force'.
	(2) move the call to red_wait_outgoing_item to red_clear_surface_drawables_from_pipe

	rhbz#994175

	When a client connection is closed surprisingly (i.e., without a FIN

	red_worker: decrease the timeout when flushing commands and waiting for the client.
	150 seconds is way too long period for holding the guest driver and
	waiting for a response for the client. This timeout was 15 seconds, but
	when off-screen surfaces ware introduced it was arbitrarily multiplied by
	10.
	Other existing related bugs emphasize why it is important to decrease
	the timeout:
	(1) 994211 - the qxl driver waits for an async-io reponse for 60 seconds
	    and after that, it switches to sync-io mode. Not only that the
	    driver might use invalid data (since it didn't wait for the query to
	    complete), falling back to sync-io mode introduces other errors.
	(2) 994175 - spice server sometimes doesn't recognize that the client
	             has disconnected.
	(3) There might be cache inconsistency between the client and the server,
	and then the display channel waits indefinitely for a cache item (e.g., bug
	977998)

	This patch changes the timeout to 30 seconds. I tested it under wifi +emulating 2.5Mbps network,
	together with playing video on the guest and changing resolutions in a loop. The timeout didn't expired
	during my tests.

	This bug is related to rhbz#964136 (but from rhbz#964136 info it is still not
	clear why the client wasn't responsive).

	reds: s/red_client_disconnect/red_channel_client_shutdown inside callbacks
	When we want to disconnect the main channel from a callback, it is
	safer to use red_channel_client_shutdown, instead of directly
	destroying the client. It is also more consistent with how other
	channels treat errors.
	red_channel_client_shutdown will trigger socket error in the main channel.
	Then, main_channel_client_on_disconnect will be called,
	and eventually, main_dispatcher_client_disconnect.

	I didn't replace calls to reds_disconnect/reds_client_disconnect in
	places where those calls were safe && that might need immediate client
	disconnection.

	decouple disconnection of the main channel from client destruction
	Fixes rhbz#918169

	Some channels make direct calls to reds/main_channel routines. If
	these routines try to read/write to the socket, and they get socket
	error, main_channel_client_on_disconnect is called, and triggers
	red_client_destroy. In order to prevent accessing expired references
	to RedClient, RedChannelClient, or other objects (inside the original call, after
	red_client_destroy has been called) I made the call to
	red_client_destroy asynchronous with respect to main_channel_client_on_disconnect.
	I added MAIN_DISPATCHER_CLIENT_DISCONNECT to main_dispatcher.
	main_channel_client_on_disconnect pushes this msg to the dispatcher,
	instead of calling directly to reds_client_disconnect.

	The patch uses RedClient ref-count in order to handle a case where
	reds_client_disconnect is called directly (e.g., when a new client connects while
	another one is connected), while there is already CLIENT_DISCONNECT msg
	pending in the main_dispatcher.

	Examples:
	(1) snd_worker.c

	    snd_disconnect_channel()
	        channel->cleanup() //snd_playback_cleanup
	            reds_enable_mm_timer()
	                .
	                .
	                main_channel_push_multi_media_time()...socket_error
	                    .
	                    .
	                    red_client_destory()
	                        .
	                        .
	                        snd_disconnect_channel()
	                            channel->cleanup()
	                                celt051_encoder_destroy()
	            celt051_encoder_destory() // double release

	Note that this bug could have been solved by changing the order of
	calls: e.g., channel->stream = NULL before calling cleanup, and
	some other changes + reference counting. However, I found other
	places in the code with similar problems, and I looked for a general
	solution, at least till we redesign red_channel to handle reference
	counting more consistently.

	(2) inputs_channel.c

	    inputs_connect()
	        main_channel_client_push_notify()...socket_error
	                .
	                .
	            red_client_destory()
	                .
	                .
	        red_channel_client_create() // refers to client which is already destroyed

	(3) reds.c

	    reds_handle_main_link()
	       main_channel_push_init() ...socket error
	                .
	                .
	            red_client_destory()
	                .
	                .
	       main_channel_client_start_net_test(mcc) // refers to mcc which is already destroyed

	    This can explain the assert in rhbz#964136, comment #1 (but not the hang that occurred before).

	main_dispatcher: add ref count protection to RedClient instances

	red_channel: prevent adding and pushing pipe items after a channel_client has diconnected
	Fixes: leaks of pipe items & "red_client_destroy: assertion `rcc->send_data.size == 0'"

	red_channel_disconnect clears the pipe. It is called only once. After,
	it was called, not items should be added to the pipe.

	An example of when this assert can occur:
	on_new_cursor_channel (red_worker.c), pushes 2 pipe items.
	When it pushes the first pipe item, if the client has disconnected,
	it can hit a socket error, and then, red_channel_client_disconnect is called.
	The second call to adding a pipe item, will add the item to
	the pipe. red_channel_client_pipe_add_type also calls
	red_channel_client_push, which will update the send_data.size.
	Then, the push will also hit a socket error, but red_channel_client_disconnect
	won't clear the pending pipe item again, since it was already called.
	When red_client_destory is called, we hit assertion `rcc->send_data.size
	== 0'.
	Note that if a pipe item is added to the pipe after
	red_channel_client_disconnect was called, but without pushing it,
	we should hit "spice_assert(rcc->pipe_size == 0)".

2013-07-05  David Gibson  <david@gibson.dropbear.id.au>

	Use RING_FOREACH_SAFE in red_channel.c functions which are missing it
	Currently, both red_channel_pipes_add_type() and
	red_channel_pipes_add_empty_msg() use plaing RING_FOREACH() which is not
	safe versus removals from the ring within the loop body.

	Although it's rare, such a removal can occur in both cases.  In the case
	of red_channel_pipes_add_type() we have:
	    red_channel_pipes_add_type()
	    -> red_channel_client_pipe_add_type()
	        -> red_channel_client_push()

	And in the case of red_channel_client_pipes_add_empty_msg() we have:
	    red_channel_client_pipes_add_empty_msg()
	    -> red_channel_client_pipe_add_empty_msg()
	        -> red_channel_client_push()

	But red_channel_client_push() can cause a removal from the clients ring if
	a network error occurs:
	    red_channel_client_push()
	    -> red_channel_client_send()
	        -> red_peer_handle_outgoing()
	            -> handler->cb->on_error callback
	            =  red_channel_client_default_peer_on_error()
	                -> red_channel_client_disconnect()
	                    -> red_channel_remove_client()
	                        -> ring_remove()

	When this error path does occur, the assertion in RING_FOREACH()'s
	ring_next() trips, and the process containing the spice server is aborted.
	i.e. your whole VM dies, as a result of an unfortunately timed network
	error on the spice channel.

	Please apply.

	red_worker: fix for stuck display_channel over WAN (jpeg_enabled=true)
	The image descriptor flags shouldn't be copied as is from the flags that
	were set by the driver. Specifically, the CACHE_ME flag shouldn't be copied,
	since it is possible that (a) the image won't be cached (b) the image
	is already cached, but in its lossy version, and we may want to set the bit for
	CACHE_REPLACE_ME, in order to cache it in its lossless version.
	In case (b), the client first looks for the CACHE_ME flag, and only if
	it is not set it looks for CACHE_REPLACE_ME (see canvas_base.c). Since both flags where set,
	the client ignored REPLACE_ME, and didn't turned off the lossy flag of the
	cach item. Then, when a request from this lossles item reached the
	client (FROM_CACHE_LOSSLESS), the client display channel waited
	endlessly for the lossless version of the image.

	red_channel: replace an assert upon threads mismatch with a warning
	The assert:
	spice_assert(pthread_equal(pthread_self(), client->thread_id))
	and the assert:
	spice_assert(pthread_equal(pthread_self(), rcc->channel->thread_id))
	were coded in order to protect data that is accessed from the main
	context (red_client and most of the channels), from
	access by threads of other channels (namely, the display and cursor
	channels), and vice versa.
	However, some of the calls to the sound channel interface,
	and also the char_device interface, can be done from the vcpu thread.
	It doesn't endanger these channels internal data, since qemu use global
	mutex for the vcpu and io threads.
	Thus, pthread_self() can be !=  channel->thread_id, if one of them is
	the vcpu thread and the other is the io-thread, and we shouldn't assert.

	Future plans: A more complete and complicated solution would be to manage our own thread for
	spice-channels, and push input from qemu to this thread, instead of
	counting on the global mutex of qemu

	The patch also removes updating dcc->streams_max_bit_rate when
	the bit_rate held by the main_channel is larger than it. It is not necessary
	since we compare those 2 values each time we set the initial bit rate
	for a stream.

	red_worker: fix incorrect is_low_bandwidth after migrating a low bandwidth connection
	rhbz#956345

	After a spice session has been migrated, we don't retest the network
	(user experience considerations). Instead, we obtain the is_low_bandwidth flag
	from the src-server, via the migration data.
	Before this patch, if we migrated from server s1 to s2 and then to s3,
	and if the connection to s1 was a low bandwidth one, we erroneously
	passed is_low_bandwidth=FALSE from s2 to s3.

	The connection to the target server is established before migration

	before migration completes (because the observed roundtrip duration will

	server: Add public spice_qxl_driver_unload method
	With a SPICE_DISPLAY_CAP_MONITORS_CONFIG capable client, the client needs to
	know what part of the primary to use for each monitor. If the guest driver
	does not support this, the server sends messages to the client for a
	single monitor spanning the entire primary.

	As soon as the guest calls spice_qxl_monitors_config_async once, we set
	the red_worker driver_has_monitors_config flag and stop doing this.

	This is a problem when the driver gets unloaded, for example after a reboot
	or when switching to a text vc with usermode mode-setting under Linux.

	To reproduce this start a multi-mon capable Linux guest which uses
	usermode mode-setting and then once X has started switch to a text vc. Note
	how the client window does not only not resize, if you try to resize it
	manually you always keep blackborders since the aspect is wrong.

	This patch is the spice-server side of fixing this, it adds a new
	spice_qxl_driver_unload method which clears the driver_has_monitors_config
	flag.

	The other patch needed to fix this is in qemu, and will calls this new method
	from qxl_enter_vga_mode.

	server/red_worker.c: use the bit rate of old streams as a start point for new streams
	mjpeg_encoder modify the initial bit we supply it, according to the
	client feedback. If it reaches a bit rate which is higher than the

	red_worker: video streams - adjust client playback latency

	reds: support mm_time latency adjustments
	When there is no audio playback, we set the mm_time in the client to be older
	than the one in the server by at least the requested latency (the delta is
	actually bigger, due to the network latency).
	When there is an audio playback, we adjust the mm_time in the client by

	red_worker: notify mjpeg_encoder on server frame drops

	red_worker: support SPICE_MSGC_DISPLAY_STREAM_REPORT
	update mjpeg_encoder with reports from the client about

	red_worker: start using mjpeg_encoder rate control capabilities
	This patch only employs setting the stream parameters based on
	the initial given bit-rate, the latency, and the encoding size.
	Later patches will also employ mjpeg_encoder response to client reports,
	and its control over frame drops.

	The patch also removes old stream bit rate calculations that weren't
	used.

	server/red_worker: enable latency monitoring in the display channel

	red_worker: stream - update periodically the input frame rate
	Periodically calculate the rate of frames arriving from the guest to the

	red_channel: monitor connection latency using MSG_PING

	server/red_worker: assign timer callbacks to worker_core, using spice_timer_queue
	display channel - supplying timeouts interface to red_channel, in order to allow
	periodic latency monitoring (see next patch).

	server: spice_timer_queue
	Each thread can create a spice_timer_queue, for managing its
	own timers.

	mjpeg_encoder: add stream warmup time, in which we avoid server and client drops
	The stream starts after lossless frames were sent to the client,
	and without rate control (except for pipe congestion). Thus, on the beginning
	of the stream, we might observe frame drops on the client and server side which
	are not necessarily related to mis-estimation of the bit rate, and we would
	like to wait till the stream stabilizes.

	mjpeg_encoder: keep the average observed fps similar to the defined fps
	The actual frames distribution does not necessarily fit the
	condition "at least one frame every (1000/rate_contorl->fps)
	milliseconds".
	For keeping the average frame rate close to the defined fps, we
	periodically measure the current average fps, and modify
	rate_control->adjusted_fps accordingly. Then, we use
	(1000/rate_control->adjusted_fps) as the interval between the
	frames.

	mjpeg_encoder: move the control over frame drops to mjpeg_encoder

	mjpeg_encoder: update the client with estimations for the required playback latency
	The required client playback latency is assessed based on the current
	estimation of the bit rate, the network latency, and the encoding size
	of the frames. When the playback delay that is reported by the client
	seems too small, or when the stream parameters change, we send the
	client an updated playback latency estimation.

	mjpeg_encoder: modify stream bit rate based on server side pipe congestion
	Downgrading stream bit rate when the input frame rate in the server
	exceeds the output frame rate, and frames are being dropped from the
	output pipe.

	mjpeg_encoder: adjust the stream bit rate based on periodic client feedback
	mjpeg_encoder can receive periodic reports about the playback status on
	the client side. Then, mjpeg_encoder analyses the report and can
	increase or decrease the stream bit rate, depending on the report.
	When the bit rate is changed, the quality and frame rate of the stream
	are re-evaluated.

	mjpeg_encoder: re-configure stream parameters when the frame's encoding size changes
	If the encoding size seems to get smaller/bigger, re-evaluate the
	stream quality and frame rate.

	mjpeg_encoder: configure mjpeg quality and frame rate according to a given bit rate
	Previously, the mjpeg quality was always 70. The frame rate was
	tuned according to the frames' congestion in the pipe.
	This patch sets the quality and frame rate according to
	a given bit rate and the size of the first encoded frames.

	The following patches will introduce an adaptive video streaming, in which
	the bit rate, the quality, and the frame rate, change in response to
	different parameters.

	Patches that make red_worker adopt this feature will also follow.

	server/red_worker: streams: moving mjpeg_encoder from Stream to StreamAgent
	The mjpeg_encoder should be client specific, and not shared between
	different clients**, for the following reasons:
	(1) Since we use abbreviated jpeg datastream for mjpeg, employing the same
	    mjpeg_encoder for different clients might cause errors when the
	    clients decode the jpeg data.
	(2) The next patch introduces bit rate control to the mjpeg_encoder.
	    This feature depends on the bandwidth available, which is client
	    specific.

	** at least till we change multi-clients not to re-encode the same
	   streams.

	red_worker: stream agent - fix miscounting of frames
	Frames counting was skipped when the previous frame was already
	sent completely to the client.

	red_worker.c: fix not destroying streams before sending MSG_MIGRATE
	When qemu migration completes, we need to stop the streams, and to send
	the corresponding upgrade_items to the client.
	Otherwise, (1) the client might display lossy regions that we don't track
	(streams are not part of the migration data).
	(2) streams_timeout may occur after MSG_MIGRATE has been sent, leading
	to messages being sent to the client after MSG_MIGRATE and before
	MSG_MIGRATE_DATA (e.g., STREAM_CLIP, STREAM_DESTROY, DRAW_COPY).
	No message besides MSG_MIGRATE_DATA should be sent after
	MSG_MIGRATE.

	When a msg other than MIGRATE_DATA reached spice-gtk after MSG_MIGRATE,
	spice-gtk sent it to dest server as the migration data, and the dest
	server crashed with a "bad message size" assert.

	(remote-viewer:18402): GSpice-CRITICAL **: spice_channel_iterate_read: assertion `c->state != SPICE_CHANNEL_STATE_MIGRATING' failed

	inputs-channel: Handle printing of insecure keyboard notify
	This is clearly something which should be handled in the inputs_channel code,
	rather then having a special case for it in the generic channel handling

	server/reds: Send the agent a CLIENT_DISCONNECTED msg on client disconnect
	Client -> agent messages can spawn multiple VDIChunks. When this happens
	the agent re-assembles the chunks into a complete VDAgentMessage before
	processing it. The server only guarentees coherency at the chunk level,
	so it is not possible for a partial chunk to get delivered to the agent.

	But it is possible for some chunks of a VDAgentMessage to be delivered to
	the agent followed by a client to disconnect without the rest of the
	VDAgentMessage being delivered!

	This will leave the agent in a wrong state, and the first messages send to it
	by the next client to connect will get seen as the rest of the VDAgentMessage
	from the previous client.

	This patch sends the agent a new VD_AGENT_CLIENT_DISCONNECTED message from the
	VDP_SERVER_PORT, on which the agent can then reset its VDP_CLIENT_PORT state.

	Note that no capability check is done for this, since the capabilities are
	something negotiated between client and agent. The server will simply always
	send this message on client disconnect, relying on older agents discarding the
	message since it has an unknown type (which both the windows and linux agents
	already do).

	char_device: Add spice_char_device_write_buffer_get_server_no_token()
	To allow the server to send agent messages without needing to wait for a
	self-token. IE for sending VD_AGENT_CLIENT_DISCONNECTED messages.

	Update spice-common

2013-03-04  Hans de Goede  <hdegoede@redhat.com>

	Silence __spice_char_device_write_buffer_get: internal buf is not available
	These messages are printed when the server tries to push a mouse event to
	the agent before the previous one has been flushed. This is a normal condition
	(which gets tracked by the reds->pending_mouse_event boolean), and as such
	it should *not* trigger the printing of error messages.

	I've seen these messages occasionally before, but with agent file-xfer they
	are trivial to trigger, simply send a large file to the agent and while it
	is transferring move the mouse over the client window. Note that due to the
	client tokens not allowing the client to completely saturate the agent
	channel mouse events do still get send to the agent, just with a slightly
	larger interval. So everything is working as designed and this spice_printerr
	is just leading to people chasing ghosts.

	worker_update_monitors_config: Drop bogus real_count accounting
	1) This does not buy us much, as red_marshall_monitors_config() also
	   removes 0x0 sized monitors and does a much better job at it
	   (also removing intermediate ones, not only tailing ones)
	2) The code is wrong, as it allocs space for real_count heads, where
	   real_count always <= monitors_config->count and then stores
	   monitors_config->count in worker->monitors_config->count, causing
	   red_marshall_monitors_config to potentially walk
	   worker->monitors_config->heads past its boundaries.

	server: Fix SpiceWorker-CRITICAL **: red_worker.c:10968:red_push_monitors_config: condition `monitors_config != NULL' failed
	During my dynamic monitor support testing today, I hit the following assert
	in red_worker.c:
	"red_push_monitors_config: condition `monitors_config != NULL' failed"

	This is caused by the following scenario:
	1) Guest causes handle_dev_monitors_config_async() to be called
	2) handle_dev_monitors_config_async() calls worker_update_monitors_config()
	3) handle_dev_monitors_config_async() pushes worker->monitors_config, this
	   takes a ref on the current monitors_config
	4) Guest causes handle_dev_monitors_config_async() to be called *again*
	5) handle_dev_monitors_config_async() calls worker_update_monitors_config()
	6) worker_update_monitors_config() does a decref on worker->monitors_config,
	   releasing the workers reference, this monitor_config from step 2 is
	   not yet free-ed though as the pipe-item still holds a ref
	7) worker_update_monitors_config() creates a new monitors_config with an
	   initial ref-count of 1 and stores that in worker->monitors_config
	8) The pipe-item of the *first* monitors_config is send, upon completion
	   a decref is done on the monitors_config, and monitors_config_decref not
	   only frees the monitor_config, but *also* sets worker->monitors_config
	   to NULL, even though worker->monitors_config no longer refers to the
	   monitor_config being freed, it refers to the 2nd monitor_config!
	9) The client which was connected when this all happened disconnects
	10) A new client connects, leading to the assert:
	    at red_worker.c:9519
	    num_common_caps=1, common_caps=0x5555569b6f60, migrate=0,
	    stream=<optimized out>, client=<optimized out>, worker=<optimized out>)
	    at red_worker.c:10423
	    at red_worker.c:11301

	Note that red_worker.c:9519 is:
	        red_push_monitors_config(dcc);
	gdb does not point to the actual line of the assert because the function gets
	inlined.

	The fix is easy and obvious, don't set worker->monitors_config to NULL in
	monitors_config_decref. I'm a bit baffled as to why that code is there in
	the first place, the whole point of ref-counting is to not have one single
	unique place to store the reference...

	This fix should not have any adverse side-effects as the 4 callers of
	monitors_config_decref fall into 2 categories:
	1) Code which immediately after the decref replaces worker->monitors_config
	   with a new monitors_config:
	   worker_update_monitors_config()
	   set_monitors_config_to_primary()
	2) pipe-item freeing code, which should not touch the worker state at all
	   to being with

	red_worker.c: clearing the stream vis_region, after it has been detached
	The stream vis_region should be cleared after the stream region was sent
	to the client losslessly. Otherwise, we might send redundant stream upgrades

	This patch inserts the drawable to the tree before the call to

	server: add "port" channel support
	A Spice port channel carry arbitrary data between the Spice client and
	the Spice server. It may be used to provide additional services on top
	of a Spice connection. For example, a channel can be associated with
	the qemu monitor for the client to interact with it, just like any
	qemu chardev. Or it may be used with various protocols, such as the
	Spice Controller.

	A port kind is identified simply by its fqdn, such as org.qemu.monitor,
	org.spice.spicy.test or org.ovirt.controller...

	The channel is based on Spicevmc which simply tunnels data between
	client and server, with a few additional messages.

	See the description of the channel protocol in spice-common history.

	agent: fix mishandling of agent data received from the client after agent disconnection
	The server can receive from the client agent data even when the agent
	is disconnected. This can happen if the client sends the agent data
	before it receives the AGENT_DISCONNECTED msg. We should receive and handle such msgs, instead
	of disconnecting the client.
	This bug can also lead to a server crash if the agent gets reconnected
	fast enough, and it receives an agent data msg from the client before MSGC_AGENT_START.

	red_worker: no need to align the stride of internal images
	Internal images are just read from the surface, compressed, and sent to the client.
	Then, they are destroyed. I can't find any reason for aligning their memory.

	red_worker: fix sending internal images with stride > bpp*width to lz compression
	rhbz#876685

	The current lz implementation does not support such bitmaps.
	The following patch will actually prevent allocating stride > bpp*width
	for internal images.

	red_worker.c: fix memory corruption when data from client is bigger than 1024 bytes
	Previously, there was no check for the size of the message received from
	the client, and all messages were read into a buffer of size 1024.
	However, migration data can be bigger than 1024. In such cases, memory
	corruption occurred.

	red_worker.c: fix not sending all pending messages when the device is stopped
	red_wait_outgoing_item only waits till the currently outgoing msg is
	completely sent.
	red_wait_outgoing_items does the same for multi-clients. handle_dev_stop erroneously called
	red_wait_outgoing_items, instead of waiting till all the items in the
	pipes are sent.
	This waiting is necessary because after drawables are sent to the client, we release them from the
	device. The device might have been stopped due to moving to the non-live
	phase of migration. Accessing the device memory during this phase can lead
	to inconsistencies.

	Also, MSG_MIGRATE should be the last message sent to the client, before
	MSG_MIGRATE_DATA. Due to this bug, msgs were marshalled and sent after
	handle_dev_stop and after handle_dev_display_migrate which sometimes led
	to the release of surfaces, and inserting MSG_DISPLAY_DESTROY_SURFACE
	after MSG_MIGRATE.

	This patch also removes the calls to red_wait_outgoing_items, from
	dev_flush_surfaces. They were unnecessary.

	smartcard.c: avoid marshalling migration data with reference to a memory that might be released before send has completed
	The current solution just copy the buffer. Currently data that is read
	from the guest is always copied before sending it to the client. When we
	will have ref count for these buffers, we can also use it for marshalling
	the migration data.

	red_worker.c: fix marshalling of migration data
	fix calling spice_marhsaller_add_ref with memory on stack

	reds.c: fix calls to spice_marshaller_add_ref with ptr to memory that might be released before sending

	char_device.c: when the state is destroyed, also free the buffer that is being written to the device

	char_device.c: add ref count for write-to-device buffers
	The ref count is used in order to keep buffers that were in the write
	queue and now are part of migration data, in case the char_device state
	is destroyed before we complete sending the migration data.

	char_device.c: fix call to spice_marshaller_add_ref with memory on stack
	rhbz#862352

2012-11-12  Yonit Halperin  <yhalperi@redhat.com>

	red_worker.c: fix calling set_client_capabilities when it is unsupported by qemu
	The erroneous call was in handle_dev_start.
	This patch also fixes not calling set_client_capabilities when the
	qxl major_version is > 3.

	display seamless migration: no need to trace the generation of the primary surface
	We no longer process destroy_primary or destroy_surfaces while waiting
	for migration data.

	display seamless migration: don't process both cmd ring and dispatcher queue till migration data is received
	fix: rhbz#866929

	At migration destination side, we need to restore the client's surfaces
	state, before sending surfaces related messages.
	Before this patch, we stopped the processing of only the cmd ring, till migration data
	arrived.
	However, some QXL_IOs require reading and rendering the cmd ring (e.g.,
	update_area). Moreover, when the device is reset, after destroying all
	surfaces, we assert (in qemu) if the cmd ring is not empty (see
	rhbz#866929).
	This fix makes the red_worker thread wait till the migration data arrives
	(or till a timeout), and not process any input from the device after the
	vm is started.

	Revert "server: add websockets support via libwebsockets"
	This reverts commit 63bb37276e028ab1b1c156c9e7907bf22b6d5952.

	server/red_worker: don't call set_client_capabilities if vm is stopped
	We try to inject an interrupt to the vm in this case, which we cannot do

	RHBZ: https://bugzilla.redhat.com/show_bug.cgi?id=870972

	server/red_worker: wip: VALIDATE_SURFACE macros, remove asserts (but too late - should be done earlier)

	release 0.12.1

	server: add websockets support via libwebsockets
	New API: spice_server_set_ws_ports

	This adds an optional dependency on libwebsockets. You need to get my
	patched 0.0.3 version here:
	 git://people.freedesktop.org/~alon/libwebsockets

	There is no qemu patches yet, to test change in reds.c the default value
	of spice_ws_port to 5959 (for the default of spice-html5).

	For testing there is an online client at
	 http://spice-space.org/spice-html5/spice.html

	Known issues:
	 1. The tester (server/tests/test_display_no_ssl) gets into dropping all
	  data after a few seconds, I think it's an issue with the implemented
	  watches, but haven't figured it out.

	 2. libwebsocket's read interface is inverted to what our code expects,
	 i.e. there is no libwebsocket_read, so there is an additional copy
	 involved (see RedsWebSocket). This can be fixed.

	 3. Listening on a separate port. Since the headers are different, we
	 could listen on the same port (first three bytes RED/GET). I don't know
	 if we want to?

	Todos:
	 1. SSL not implemented yet. Needs some thought as to how.

	 2. Serve spice-html5 when accessed as a http server. Nice to have.

	server: red_dispatcher: check major/minor of qxl for client_monitors_config
	This solves a problem with new spice-server and old qemu-kvm, where spice thinks
	qif->client_monitors_config exists, while it does not exist in qemu-kvm.

	Also "major > required_major" was added to the condition.
	Also only the specific RedDispatcher is checked (and not all dispatchers).

	inputs_channel: Fix wrong handling of key up/down on big endian
	The client will send 0x000000## codes for regular keys, and 0x0000##e0 codes
	for extended keys. The current code which simply walks the uint32_t code in
	memory order relies on the memory order being little endian, which will
	clearly fail on big endian machines, this fixes this.

	snd channel: fix accessing freed memory
	snd_channel_put freed "channel", and then channel->worker was accessed.

	Fix PlaybackChannel forward declaration
	This caused a jenkins build failure:

	snd_worker.c:148: error: redefinition of typedef 'PlaybackChannel'
	snd_worker.c:126: note: previous declaration of 'PlaybackChannel' was here

2012-10-01  Andrew Eikum  <aeikum@codeweavers.com>

	server: Access the correct SndChannel for a given AudioFrame
	The client of _get_buffer() holds a ref to the SndChannel, and we
	should access that SndChannel when _put_samples() is called, not the one
	that happens to currently be attached to the Interface.

	server: Don't release SndChannel twice from worker reference
	When we release the SndChannel reference during
	snd_disconnect_channel(), we need to set the pointer to NULL so it
	doesn't get released again on client reconnect during
	snd_set_playback_peer(). This can happen when a reference is held from
	_playback_get_buffer().

2012-09-20  Christophe Fergeau  <cfergeau@redhat.com>

	reds: Report an error when reds_char_device_add_state fails
	This used to abort with spice_error. The caller currently does
	not check spice_server_char_device_add_interface return value, but
	it's still cleaner to report an error in this case.

	reds: Check errors returned from SSL_CTX_set_cipher_list

	reds: Report errors from load_dh_params

	reds: Check reds_init_ssl errors
	Now that this function can fail, propagate any error up to the
	caller. This allows qemu to fail when an SSL initialization error
	occurred.

	reds: report SSL initialization errors
	Errors occurring in reds_init_ssl used to be fatal through the use
	of spice_error, but this was downgraded to non-fatal spice_warning
	calls recently. This means we no longer error out when invalid SSL
	(certificates, ...) parameters are passed by the user.
	This commit changes reds_init_ssl return value from void to int so
	that errors can be reported to the caller.

	reds_init_net: report errors on watch setup failures
	We used to be aborting in such situations, but this was changed
	during the big spice_error/printerr cleanup. We are currently
	outputting a warning but not reporting the error with the caller
	when reds_init_net fails to register listening watches with the
	mainloop. As it's unlikely that things will work as expected in
	such cases, better to error out of the function instead of pretending
	everything is all right.

	reds: Abort on BN-new failures
	BN_new returns NULL on allocation failures. Given that we abort
	on malloc allocation failures, we should also abort here. The
	current code will segfault when BN_new fails as it immediatly tries
	to use the NULL pointer.

	Release 0.12.0

2012-09-13  Alon Levy  <alevy@redhat.com>

	server/spice-server.syms: add missing global labels
	Although global is the default, this makes the file more consistent.

	server/Makefile.am: fix for make distcheck
	Doesn't make sense to distribute test_spice_version.sh, so just
	ensure the build passes if it doesn't exist.

	spice-server 0.11.5
	Added api:
	 QXL interface (3.2)
	  client_monitors_config

	server/tests: agent mock, client_monitors_config

	server: Filter VD_AGENT_MONITORS_CONFIG
	If the guest supports client monitors config we pass it the
	VDAgentMonitorsConfig message via the
	QXLInterface::client_monitors_config api instead of via the vdagent.

	server/reds: reuse already defined local

	server/red_dispatcher: client_monitors_config support
	Adds two functions:
	 - red_dispatcher_use_client_monitors_config:
	   check that QXLInterface supports client_monitors_config and that it's
	   functional.
	 - red_dispatcher_client_monitors_config:
	   send the client monitors configuration to the guest.

	server: add QXLInterface::client_monitors_config
	Used to implement guest monitor configuration change similarly to real
	hardware in conjunction with the new qemu interrupt
	QXL_INTERRUPT_CLIENT_MONITORS_CONFIG. client_monitors_config is also
	used to probe the support by the interface. If it is not supported we
	send the message to the guest agent.
	This makes a linux qxl driver similar to existing kms drivers.

	The logic is:

	For every received VDAgentMonitorsConfig:
	 if client_monitors_config(NULL):
	  write client configuration to pci rom BAR.
	  send interrupt to guest
	  guest kernel reads configuration from rom BAR.
	  guest kernel issues event to user space
	  user space reads (libdrm) and reconfigures (libXRandr)
	 else: (current implementation)
	  write message to guest agent
	  guest agent issues reconfiguration via XRandr / windows Escape ioctl to kernel

	update spice-common module
	For qxl client_monitors_config support.

	Update spice-common to get A8 surface definitions
	Latest spice needs these definitions from spice-protocol

2012-09-07  Søren Sandmann Pedersen  <ssp@redhat.com>

	Bump spice.h version number to 0.11.4
	No new symbols are added, but there is an addition to QXLInterface:

	    void (*set_client_capabilities)(QXLInstance *qin,
	                                    uint8_t client_present,
	                                    uint8_t caps[58]);

	Set a8 capability in the QXL device if supported by the client

	Process outstanding commands in the ring after changing capability bits
	When a new client connects, there may be commands in the ring that it
	can't understand, so we need to process these before forwarding new
	commands to the client. By doing this after changing the capability
	bits we ensure that the new client will never see a command that it
	doesn't understand (under the assumption that the guest will read and
	obey the capability bits).

	Acked-by: Alon Levy <alonl@redhat.com>

2012-09-06  Søren Sandmann Pedersen  <ssp@redhat.com>

	Add new set_client_capabilities() interface to QXLInstance
	A new interface

	  set_client_capabilities (QXLInstance *qin,
	  			   uint8_t client_present,
	  			   uint8_t caps[58]);

	is added to QXLInstance, and spice server is changed to call it
	whenever a client connects or disconnects. The QXL device in response
	is expected to update the client capability bits in the ROM of the
	device and raise the QXL_INTERRUPT_CLIENT interrupt.

	There is a potential race condition in the case where a client
	disconnects and a new client with fewer capabilities connects. There
	may be commands in the ring that the new client can't handle. This
	case is handled by first changing the capability bits, then processing
	all commands in the ring, and then start forwarding commands to the
	new client. As long as the guest obeys the capability bits, the new
	client will never see anything it doesn't understand.

	enable seamless migration and set migration protocol version

	inputs channel migration: don't send any msg after MSG_MIGRATE
	Pending motion acks, and keyboard modifiers messages will be sent
	by the destination after receiving the migration data.

	inputs_channel: send and handle migration data

	migration_protocol: add inputs channel migration data
	Storing the motion count in uint16_t and not in uint32_t since
	the exact count is not important, just its division in
	SPICE_INPUT_MOTION_ACK_BUNCH (see the next 2 patches).

	main_channel: don't expect init msg in a seamless migration destination
	If the server is a destination of seamless migration, send msgs to the client,
	even though an init msg has not been sent to the client.

	red_channel: set send_data.last_sent_serial in red_channel_client_set_message_serial
	red_channel_client_set_message_serial is called for setting
	the serial of the display channel messages after migration (on the
	destination side). The serial is retrieved from the migration data.

	red_channel: remove unused migrate flag from RedChannel
	The relevant flags reside in RedChannelClient and RedClient

	snd_worker: handling migration
	The playback and record channel send SPICE_MSG_MIGRATE to the client.
	Both playback and record channel does not have a state to restore:
	while in the legacy migration implementation the record channel
	used to restore the mode and start time, it looks unnecessary since
	the client receives from the src MSG_RECORD_STOP before the migration
	completion notification (when the vm is stopped). Afterwards, when the vm
	starts on the dest side, the client receives MSG_RECORD_START.

	snd_channel: fix double release
	Due to the fix in the previous patch, snd_disconnect_channel can be
	called both when there is write/read error in the channel, or from
	red_client_destroy (which calls client_cbs.disconnect).
	Multiple calls to snd_disconnect_channel resulted in calling
	channel->cleanup(channel) more than once (double release).

	red_channel (dummy): fix not adding dummy RedChannelClient to the client
	snd channel wasn't added to be part of the client's channels list.
	As a result, when the client was destroyed, or migrated, snd channel
	client wasn't destroy, or its migration callback wasn't called.

	However, due to adding dummy channels to the client, we need special
	handling for calls to disconnecting dummy channel clients.

	TODO: we need to refactor snd_worker to use red_channel

	display migration: restore destination state
	Restoring display channel from migration data.
	Not notifying client about changes that are artifacts of loading the vm.
	Remove legacy migration code.

	display migration: marshall migration data

	display & cursor migration: send SPICE_MSG_MIGRATE

	migration_protocol: add display channel migration data

	inputs channel: use the default red_channel behaviour for client_cbs.migrate
	The default callback sends SPICE_MSG_MIGRATE to the client.

	inputs channel: fix using spice messages enums as pipe items type
	A channel pipe item type must start from PIPE_ITEM_TYPE_CHANNEL_BASE.
	SPICE_MSG_MIGRATE value eq. PIPE_ITEM_TYPE_SET_ACK. Setting a pipe item
	type to SPICE_MSG_MIGRATE, leads to red_channel handling PIPE_ITEM_TYPE_SET_ACK.

	char_device: don't connect a migrated client if the state of the device might have changed since it was created
	If reading/writing from the device have occured before migration data
	has arrived, the migration data might no longer be relvant, and we
	disconnect the client.

	main: restore state from migration data
	Also removed old migration leftovers.

	main: send migration data
	Also removed some unused definitions from reds that used to belong to
	old agent and migration code.

	main: send MSG_MIGRATE upon vm migration completion
	Before sending the above msg, if there is a pending partial msg that
	has been read from the agent, we send it to the client. The alternative
	was to keep the msg as part of the migration data, and then
	to send it to the destination server via the client and to wait there
	for the msg chunk completion, before sending it to the client. Of
	course, the latter is less efficient.

	reds: s/HADER/HEADER

	migration_protocol: add migration data for the main channel (mainly for the agent)

	main_channel: fix using spice messages enums as pipe items type
	A channel pipe item type must start from PIPE_ITEM_TYPE_CHANNEL_BASE.
	SPICE_MSG_MIGRATE value eq. PIPE_ITEM_TYPE_SET_ACK. Setting a pipe item
	type to SPICE_MSG_MIGRATE, leads to red_channel handling PIPE_ITEM_TYPE_SET_ACK.

	Also removed sending SPICE_MSG_MIGRATE. It will be handled in the next
	patch.

	red_channel: introduce PIPE_ITEM_TYPE_EMPTY_MSG
	The pipe item is used for sending messages that don't have body.

	smartcard: restore state after migration from migration data

	smartcard migration: send migration data

	migration_protocol: add migration data for smartcard

	smartcard: send MSG_MIGRATE upon vm migration completion
	The above is the default behaviour for red_channel_client, if
	client_cbs.migrate is not registered as part of red_channel_register_client_cbs

	smartcard: fix PIPE_ITEMs enum indexing
	The enum should start from PIPE_ITEM_TYPE_CHANNEL_BASE, otherwise,
	PIPE_ITEM_TYPE_ERROR is handled like PIPE_ITEM_TYPE_SET_ACK.

	smartcard: change the timing of attaching a client to SpiceCharDeviceState
	Attach/detach a client to a SpiceCharDeviceState upon its
	connection/disconnection, instead of upon reader_add/remove messages.
	When the client is removed from a SpiceCharDeviceState, all the
	messages from this client are removed from the device write queue.
	This shouldn't happen when we only receive reader_remove and the
	client is still connected.

	spicevmc migration: restore migration dest state from migration data

	spicevmc migration: send migration data

	spicevmc: send MSG_MIGRATE upon vm migration completion
	The above is the default behaviour for red_channel_client, if
	client_cbs.migrate is not registered as part of red_channel_register_client_cbs

	migration_protocol: add migration data for spicevmc

	char device migration: restore state at destination from migration data

	char device migration: don't read or write from/to the device while waiting for migraion data

	char device migration: marshall migration data

	char_device: variable token price for write buffers
	When restoring migration data, we also restore data that is addressed to
	the device, and that might have been originated from more than 1
	message. When the write buffer that is assoicated with this data is
	released, we need to free all the relevant tokens.

	migration_protocol: add migration data for char devices

	replace some migration related spice_error calls with info/warning

	seamless migration: migration completion on the destination side
	Tracking the channels that wait for migration data. If there
	is a new migration process pending, when all the channels have
	restored their state, we begin the new migration.

	red_channel: handle sending SPICE_MSG_MIGRATE
	The relevant code is common to all channels.

	The patch also contains a fix to the return value for
	handle_migrate_data callback: s/uint64_t/int

	red_channel: fix pipe item leak

	seamleass migration: manage post migration phase in the src side
	In semi-seamless, SPICE_MSG_MAIN_MIGRATE_END is sent.
	In seamless, each channel migrates separately.

	The src waits till all the clients are disconnected (or a timeout), and
	then it notifies qemu that spice migration has completed.

	The patch doesn't include the per-channel logic for seamless migration
	(sending MSG_MIGRATE, MIGRATE_DATA, etc.).

	seamless migration: pre migration phase on the destination side
	- handle SPICE_MSGC_MAIN_MIGRATE_DST_DO_SEAMLESS
	- reply with SPICE_MSG_MAIN_MIGRATE_DST_SEAMLESS_ACK/NACK
	- prepare the channels for migration according to the migration
	   type (semi/seamless)

	see spice-protocol for more details:
	commit 3838ad140a046c4ddf42fef58c9727ecfdc09f9f

	seamless migration: pre migration phase on the src side
	sending SPICE_MSG_MAIN_MIGRATE_BEGIN_SEAMLESS and handling
	SPICE_MSGC_MAIN_MIGRATE_CONNECTED_SEAMLESS

	The src side signals the client to establish a connection
	to the destination.
	In seamless migration, the client is also used to perform
	a sort of handshake with the destination, for verifying
	if seamless migration can be supported.

	see spice-protocol for more details:
	commit 3838ad140a046c4ddf42fef58c9727ecfdc09f9f

	seamless-migration: update spice-common submodule
	Also Update server and client according to the change of
	SpiceMsgMainMigrationBegin: it now holds all the fields inside
	SpiceMigrationDstInfo.

	seamless-migration: add migration_protocol.h
	The file will hold the declarations of the different migration
	data messages (depending on the channel), that will be passed
	from the src server to the dst server, via the client, using
	SPICE_MSG_MIGRATE_DATA.

	bump version to 0.11.2
	New api entries:
	    spice_server_vm_start
	    spice_server_vm_stop
	    spice_server_set_seamless_migration

	spice.h: add spice_server_set_seamless_migration
	This new call is used in order to identify whether qemu, or
	the management (e.g. libvirt), support seamless migration.
	If it is supported, qemu spice cmd-line configuration should have
	seamless-migration=on.

	In addition, we disable seamless migration support if multiple clients
	are allowed. Currently, only one client is supported.

	spice_server_vm_start/stop: notify red_dispatcher on vm start/stop
	Till now, red_worker was notfied about vm status changes via QXLWorker->start/stop
	(or spice_qxl_start/stop).
	Newer qemu, that supports calling spice_server_vm_start/stop, will call only
	these routines, and won't call QXLWorker->start/stop.

	spice.h: add entries for tracking vm state
	When vm state changes (started/stopped), we notify all the
	attached SpiceCharDeviceStates about the change. This is mainly required
	for avoiding writing/reading to/from the device during the non-live
	stage of migration.

	spice version will be bumped in one of the following patches.

	reds: add tracking for char devices
	The list of attached char_devices will be used in the next patch
	for notifying each instance of SpiceCharDeviceState when the vm
	is started or stopped.

	agent: don't attempt to read from the device if it was released
	if vdi_port_read_buf_process failes, we detach the agent and also release
	the read buffer. We shouldn't try reading from the device afterwards.

	agent: reset client tokens when notifying on agent connection
	send SPICE_MSG_MAIN_AGENT_CONNECTED_TOKENS

	red_channel: add red_channel_test_remote_cap
	for checking if all the channel clients connected support the cap

2012-08-24  Søren Sandmann Pedersen  <ssp@redhat.com>

	Add support for Composite command to the client
	All the real work is being done in spice-common, so this patch is just
	hooking up the virtual calls and adding the SPICE_DISPLAY_CAP_COMPOSITE
	capability.

	Add support for QXLComposite to spice server
	In red-parse-qxl.c add support for parsing QXLComposite into
	SpiceComposite. In red-worker.c add support for marshalling
	SpiceComposite onto the wire.

	Add support for LZ compression of A8 images
	Graduality is irrelevant for A8 images, so instead of using RGB-ness
	as a short-cut, add a new macro BITMAP_FMT_HAS_GRADUALITY() that
	returns true for the existing RGB images, but false for A8.

2012-07-25  Yonit Halperin  <yhalperi@redhat.com>

	red_worker: Fix reference counting for the current frame (drawable) of a stream
	After marshalling MSG_STREAM_CREATE, there is no need to ref and
	unref stream->current before and after completing the sending of the
	message (correspondingly). The referencing is unnecessary because all
	the data that is required from the drawable (the clipping), is copied
	during marshalling, and no field in the drawable is referenced (see
	spice_marshall_msg_display_stream_create).

	Moreover, the referencing was bugous:
	While display_channel_hold_pipe_item and
	display_channel_client_release_item_after_push referenced and
	dereferenced, correspondingly, stream->current, stream->current might
	have changed in between these calls, and then we ended up with one drawable
	leaking, and one drawable released before its time has come (which
	of course led to critical errors).

	bump version to 0.11.1 for new spice_qxl_monitors_config_async

2012-07-22  Alon Levy  <alevy@redhat.com>

	server: add monitors_config support
	a SpiceMsgDisplayMonitorsConfig is sent on two occasions:
	 * as a result of a spice_qxl_monitors_config_async
	 * whenever a client connects and there is a previously set monitors
	   config

	Sending the new message is protected by a new cap,
	SPICE_DISPLAY_CAP_MONITORS_CONFIG

	More elaborately:
	spice_qxl_monitors_config_async receives a QXLPHYSICAL address of a
	QXLMonitorsConfig struct and reads it, caching it in the RedWorker, and
	sending it to all clients. Whenever a new client connects it receives
	a SpiceMsgDisplayMonitorsConfig message as well.

	build-sys: remove cegui/slirp and mandatory client from dist-check
	The spicec client is no longer actively maintained.

	By removing cegui from distcheck, we can avoid extra build time and
	dependencies (>150Mb extra cegui/boost on fedora)

	Slirp is not available in most distributions, afaict, making it hard
	to build consistantly accross various systems.

	The client is still build if the dependencies are present.

	build-sys: define GL flags if enabled
	The server too can use opengl, independently from client.

2012-07-05  Alon Levy  <alevy@redhat.com>

	server/reds.c: spice_printerr cleanup
	Rules for replacing spice_printerr:
	* if it's a client drop / agent drop, spice_error
	* if it's important, spice_warning
	* else, spice_info.

	The fourth rule is spice_debug if it's going to fill up the log, but
	nothing of the sort here.

	Other things this patch does:
	* changed reds_show_new_channel to reds_info_new_channel in an attempt to
	advertise it doesn't always show anything, unless SPICE_DEBUG_LOG_LEVEL
	>= SPICE_DEVUG_LOG_INFO (==3)
	* removes two lines of whitespace.
	* added "crashy" to multiple client warning (only warning introduced,
	  the rest are errors).

	server/red_worker: elevate some spice_debugs to spice_info
	Specifically all those that the previous patch converted to spice_debug.
	spice_debug contains very verbose stuff like update_area that drowns out
	those relatively rare (client connect / disconnect generated) messages.

	update spice-common for spice_info

	server/red_worker: cleanup lines starting with 5 spaces

	server/red_worker: death to spice_printerr, too verbose by far
	Replaced mostly with spice_debug, but spice_warning & spice_error as
	well where appropriate.

	smartcard: Remove redefinition of typedef 'SmartCardDeviceState'

2012-07-03  Yonit Halperin  <yhalperi@redhat.com>

	char_device.h: Remove redefinition of typedef 'SpiceCharDeviceState'
	The original definition is in spice.h

	char_device: move SpiceCharDeviceState from the header
	In addition, I also removed the no longer used wakeup callback

	smartcard: use SpiceCharDeviceState for writing to the guest device
	With SpiceCharDeviceState, the smartcard code now supports partial writes,
	and storing data that is received from the client after the device is
	stopped, instead of attempting to write it to the guest.

	smartcard: creating SmartCardChannelClient type
	The lifetime of the channel is not necessarily correlated to the life
	time of the device. In the next patch, we need to keep a reference
	to SpiceCharDeviceWriteBuffer, which might be in use even if the
	SpiceCharDeviceState is destroyed, but the channel is still connected.
	The next patch keeps this reference inside SmartCardChannelClient.

	This patch also removes the routine smartcard_readers_detach_all(rcc), which
	is unnecessary since we don't support multiple readers; even when
	we do support them, each channel client should be associated with only
	one reader (i.e., we will have different channels for different
	readers).

	smartcard: use SpiceCharDeviceState for managing reading from the device
	This patch and the following one do not introduce tokening to the smartcard
	channel. But this can be done easily later, by setting the appropriate
	variables in SpiceCharDeviceState (after adding the appropriate protocol messages,
	and implementing this in the client side).

	spicevmc: use SpiceCharDeviceState for writing to the guest device
	With SpiceCharDeviceState, spicevmc now supports partial writes,
	and storing data that is received from the client after the device is
	stopped, instead of attempting to write it to the guest.

	spicevmc: employ SpiceCharDeviceState for managing reading from the guest device
	This patch and the following one do not introduce tokening to the
	spicevmc channel. But this can be done easily later, by setting the appropriate
	variables in SpiceCharDeviceState (after adding
	the appropriate protocol messages, and implementing this in the client
	side).

	agent: employ SpiceCharDeviceState for writing to the device

	agent: use SpiceCharDeviceWriteBuffer for agent data from the client
	This is an intermediate patch. The next patch will actually
	push the buffer to the device, instead of copying it.

	agent: employ SpiceCharDeviceState for managing reading from the device

	agent: remove save/restore migration data code
	This code is never called, it was relevant for seamless migration.
	Most of the data that needs to be migrated was moved to
	SpiceCharDeviceState. When we implement seamless migration,
	we will have routines in char_device.c for migrating the relevant data.

	agent: Fix tokens handling in main_channel
	- Allow sending tokens to a specific client.
	- Do not ignore tokens that are sent from the client to the server.

	The tokens support for multiple clients and for server side tokens
	is still broken in reds. It will be fixed in following patches, when
	the server-side agent code will use the SpiceCharDeviceState api.

	Notice that ignoring the server-side tokens didn't introduce a problem
	since both the client and the server set it to ~0.

	char_device: Introducing shared flow control code for char devices.
	SpiceCharDeviceState manages the (1) write-to-device queue
	(2) wakeup and reading from the device (3) client tokens (4)
	sending messages from the device to the client/s, considering the
	available tokens.
	SpiceCharDeviceState can be also stopped and started. When the device
	is stopped, no reading or writing is done from/to the device. Messages
	addressed from the client to the device are being queued.
	Later, an api for stop/start will be added to spice.h and it should
	be called from qemu.

	This patch does not yet remove the wakeup callback from
	SpiceCharDeviceState, but once all the char devices (agent/spicevmc/smartcard)
	code will switch to the new implementation, SpiceCharDeviceState
	will be moved to the c file and its reference to the wakeup callback will be removed.

	smartcard: fix an error message

	smartcard: fix calc of remaining data size when reading more than one msg from the device

	server/red_channel: do not attempt to write if the channel client is disconnected
	The red_channel_client_event call to red_channel_client_receive might result
	in a disconnected channel client. The following call to

	server/red_channel: fix possible access to released channel clients
	Added ref count for RedChannel and RedChannelClient.

	red_channel.c/red_peer_handle_incoming call to

	a violation.

	call red_client_destory, e.g., by some violation in

	server/red_worker: fix red_wait_pipe_item_sent
	Resolves: rhbz#824384

	red_wait_pipe_item_sent mistakingly returned without waiting for sending the given pipe item
	when the channel wasn't blocked. As a result, we failed when we had to
	destroy a surface (e.g., QXL_IO_DESTROY_ALL_SURFACES) and to release all
	the drawables that are depended on it (by removing them or waiting they will be sent).
	In addition, red_wait_pipe_item_sent increased and decreased the reference to the pipe item
	using channel_cbs->hold_item, and channel_cbs->release_item. However,
	these calls can be called only by red_channel, otherwise
	display_channel_client_release_item_before_push is called twice and
	leads to a double call to ring_remove(&dpi->base).
	Instead ref/put_drawable_pipe_item should be called.

	server/red_channel: remove red_channel_client_item_being_sent
	The above routine was risky, since red_channel_client_init_send_data
	can also be called with item==NULL. Thus, not all pipe items can be tracked.
	The one call that was made for this routine was not necessary.

	server/red_worker/video: don't override the clip in areas that belong only to sized frames

	server/red_worker.c/video: add support for frames of different sizes
	rhbz #813826

	When playing a youtube video on Windows guest, the driver sometimes(**) sends
	images which contain the video frames, but also other parts of the
	screen (e.g., the youtube process bar). In order to prevent glitches, we send these
	images as part of the stream, using SPICE_MSG_DISPLAY_STREAM_DATA_SIZED.

	(**) It happens regularly with the you tube html5 player. With flash,
	it occurs when moving the cursor in the player area.

	Update the spice-common submodule
	spice-common changes: STREAM_DATA_SIZED message was added in order to support
	video streams with frames that their size is different from the initial size
	that the stream was created with.

	This patch also includes server and client adjustments to the new
	SpiceMsgDisplayStreamData.

	server/red_worker/video: don't detach a drawable from a stream due to it being rendered.
	The previous patch took care that streams will be upgraded by a surface
	screenshot and not the last frame, if necessary. Thus, there is no
	more a reason for detaching drawables from streams when they are
	rendered. Moreover, detaching such drawables can cause glitches, in
	case they are still in the pipe, and red_update_area is called
	frequently and leads to stream frames rendering.

	server/red_worker/video: upgrade stream by a screenshot instead of the last frame, if needed
	Upgrading a stream: When the stream's visible region is bigger than the one of the last
	frame, we will send an updated screenshot of the visible region, instead
	of sending the last frame losslessly.

	server/red_worker/video: maintain visible region and clip region for streams
	Differentiate between the clipping of the video stream, and the region
	that currently displays fragments of the video stream (henceforth,
	vis_region). The latter equals or contains the former one. For example,
	let c1 be the clip area at time t1, and c2 be the clip area at time t2,
	where t1 < t2. If c1 contains c2, and at least part of c1/c2, hasn't been
	covered by a non-video images, vis_region will contain c2, and also the part
	of c1/c2 that still displays fragments of the video.
	When we consider if a stream should be "upgraded" (1), due to its area
	being used by a rendering operation, or due to stopping the video, we
	should take into account the vis_region, and not the clip region (next
	patch: not upgrade by the last frame, but rather by vis_region).
	This fix will be more necessary when sized frames are introduced (see the
	following patches). Then, the vis_region might be larger
	than the last frame, and contain it, more frequently than before.

	(1) "upgrading a stream" stands for sending its last frame losslessly. Or more
	precisely, lossless resending of all the currently displayed lossy areas, that were
	sent as part of the stream.

	Ensure __STDC_FORMAT_MACROS is always defined first

	Don't truncate SPICE_FOREIGN_MENU_SOCKET
	When we get the socket name for the foreign menu socket from
	an environment variable, we cannot make assumptions about its length.
	Currently, we are strncpying to a 50 byte buffer which is easily
	too small.

	Don't limit spice controller socket name to 50 chars
	The spice controller socket name used to be hardcoded to
	/tmp/SpiceController-%lu.uds and generated using snprintf. A 50 bytes
	buffer was enough for that, but this was changed in commit 79fffbf95
	because this was predictable and allowed other users on the system
	to sniff the browser/client communication. spicec now uses the value
	of the environment SPICE_XPI_SOCKET as the name of the socket to use.
	However, since the name that is used is no longer generated by spicec,
	no assumption can be made about its size. Currently, the socket is
	created inside the user home directory, which means that if the
	user name is too long, spicec will not be able to read the controller
	socket name.
	This commit directly uses the string from getenv as he name of the
	controller socket (on Linux) instead of limiting its size to 50 characters,
	which should fix this issue.
	This fixes rhbz #804561

	Remove unused Canvas members
	The various Canvas have _max and _base variables which are not

	red_channel: remove pre_disconnect hook
	Now that red_worker's EventListener is gone there are no more users of it.

	red_worker: Rework poll code to use the watch interface
	Commit 143a1df24e83e9c1e173c16aeb76d61ffdce9598 changed red_worker_main
	from epoll to poll. But epoll has edge triggered semantics (when requested
	and we requested them), where as poll is always level triggered. And
	red_worker was relying on the edge triggered semantics, as it was always
	polling for POLLOUT, which, when edge triggered, would only cause poll
	to register an event after we had blocked on a write. But after the
	switch to regular poll, with its level triggered semantics, the POLLOUT
	condition would almost always be true, causing red_worker_main to not
	block on the poll and burn CPU as fast as it can as soon as a client was
	connected.

	Luckily we already have a mechanism to switch from polling for read only
	to polling for read+write and back again in the form of watches. So this
	patch changes the red_worker dummy watch implementation into a proper watch
	implementation, and drops the entire EventListener concept since that then is
	no longer needed.

	This fixes spice-server using 400% CPU on my quad core machine as soon as
	a client was connected to a multi head vm, and as an added bonus is a nice
	cleanup IMHO.

	red_channel: Use the channel core to remove the stream watch on disconnect
	We allow channels to have different core implementations, but we were
	relying on reds_stream_free to remove the stream watch on disconnect,
	and reds_stream_free always uses the qemu core implementation.

	So far we were getting away with this since all the alternative core
	implementations always return NULL from watch_add.

	But:
	1) The code before this patch clearly was not correct, since it was matching
	   a channel-core watch_add with a qemu-core watch_remove
	2) I plan to move red_worker over to actually using an alternative watch
	   implementation at which point this becomes a real problem

2012-03-10  Hans de Goede  <hdegoede@redhat.com>

	red_worker: Remove ref counting from the EventListener struct
	The red_worker EventListener struct is either embedded in one of:
	1) DisplayChannelClient
	2) CursorChannelClient
	3) RedWorker

	And as such gets destroyed when these get destroyed, in case 1 & 2 through
	a call to red_channel_client_destroy().

	So free-ing it when the ref-count becomes 0 is wrong, for cases:
	1) and 2) this will lead to a double free;
	3) this will lead to passing memory to free which was not returned by malloc.

	This is not causing any issues as the ref-count never gets decremented, other
	then in red_worker_main where it gets incremented before it gets decremented,
	so it never becomes 0.

	So we might just as well completely remove it.

	Notes:
	1) This is mainly a preparation patch for fixing issues introduced by
	   the move from epoll to poll
	2) Since removing the ref-counting removes the one code path where listeners
	   would get set to NULL, this patch moves the setting of NULL to
	   pre_disconnect, where it should have been done in the first place since
	   red_client_destroy calls red_channel_client_disconnect
	   (through the dispatcher) followed by red_channel_client_destroy, so
	   after pre_disconnect the listener may be gone.

	Ensure all members of ChannelCbs and ClientCbs are either assigned or NULL
	While git-bisecting another issue I ended up hitting and not recognizing
	the bug fixed by commit 7a079b452b026d6ce38f95dcc397fa64b059fffb.

	While fixing this (again) I noticed that (even after the fix) not all
	users of ChannelCbs first zero it. So this patch ensures that all users of
	ChannelCbs first zero it, and does the same for ClientCbs while at it.

	Since before this patch there were multiple zero-ing styles, some using
	memset and other using a zero initializer this patch also unifies all
	the zero-ing to use a NULL initializer for the first element.

	server: fix segfault on client disconnect

	Enabling cursor in server/tests
	    Now, cursor is being shown in all tests as a white rectangle and is
	    running in the screen doing a diagonal movement. It's a very simple
	    way to test cursor commands and is sufficient for our tests.

	Use standard IOV_MAX definition where applicable
	This is provided by <limits.h> on all platforms as long as _XOPEN_SOURCE
	is defined. On Linux, this is 1024, on Solaris, this is 16, and on any
	other platform, we now respect the value supported by the OS.

	Respect IOV_MAX if defined
	Solaris has a pitiful maximum writev vector size of only 16, so the ping
	request at initial startup destroyed this call and broke things
	immediately. Reimplement stream_writev_cb() to respect IOV_MAX and break
	the writev() calls into chunks as necessary. Care was taken to return
	the correct values as necessary so the EAGAIN handling logic can
	determine where to resume the writev call the next time around.

	red_worker: reimplement event loop using poll()
	This removes the epoll dependency we had in red_worker, which was the
	last Linux-specific call we were using in the entire Spice server. Given
	we never have more than 10 file descriptors involved, there is little
	performance gain had here by using epoll() over poll().

	The biggest change is introduction of a new pre_disconnect callback;
	this is because poll, unlike epoll, cannot automatically remove file
	descriptors as they are closed from the pollfd set. This cannot be done
	in the existing on_disconnect callback; that is too late as the stream
	has already been closed and the file descriptor lost. The on_disconnect
	callback can not be moved before the close and other operations easily
	because of some behavior that relies on client_num being set to a
	certain value.

	Use memcpy call in red_channel_create
	Rather than assign the callbacks one-by-one, we can just memcpy the
	struct into the one we have allocated in our RedChannel object, which is
	much more efficient, not to mention future-proof when more callbacks are
	added.

	Cleanup definitions of disconnect methods
	We had multiple stub methods that simply called other disconnect
	methods, making my head hurt with the indirection. Call the right
	methods at the right time and rip out the stub methods; if they are
	truely needed later they can be added again.

	red_worker: rename epoll_timeout to event_timeout
	With future patches in mind that will allow for some other
	non-Linux-specific event polling sytem to be used, rename this to a more
	generic name. All of the select/poll/epoll/kqueue family of calls are
	related to evented I/O, so 'event_' makes sense in this case.

	Add configure-time check for -Wl, --version-script option
	This is supported by the GNU linker, but not the Solaris linker, which
	is used as the default on that platform even when compiling with GCC.
	Omit passing the option to the linker on platforms that do not support
	it.

	server/spicevmc: Don't destroy the rcc twice
	spicevmc calls red_channel_client_destroy() on the rcc when it disconnects
	since we don't want to delay the destroy until the session gets closed as
	spicevmc channels can be opened, closed and opened again during a single
	session.

	This causes red_channel_client_destroy() to get called twice, triggering
	an assert, when a connected channel gets destroyed.

	This was fixed with commit ffc4de01e6f9ea0676f17b10e45a137d7e15d6ac for
	the case where: a spicevmc channel was open on client disconnected, and
	the main channel disconnect gets handled first.

	But the channel can also be destroyed when the chardev gets unregistered
	with the spice-server. This path still triggers the assert.

	This patch fixes this by adding a destroying flag to the rcc struct, and
	also moves the previous fix over to the same, more clean, method of
	detecting this special case.

	server: Don't complain if setsockopt NODELAY fails on unix sockets
	With Daniel P. Berrange's patches to allow use of pre-supplied fd's
	as channels, we can no longer be sure that our connections are TCP
	sockets, so it makes no sense to complain if a TCP/IP specific
	setsockopt fails with an errno of ENOTSUP.

	Note that this extends Daniel's commit 492ddb5d1d595e2d12208f4602b18e4432f4e6b4
	which already added the same check to server/inputs_channel.c

2012-01-13  Daniel P. Berrange  <berrange@redhat.com>

	Add a 'syntax-check' make target
	The 'make syntax-check' target is used to perform various code
	style sanity checks, as well as to detect certain trivial error
	patterns. The target is placed in GNUmakefile, instead of Makefile.am
	since it relies on GNU specific make extensions.

	The actual GNUmakefile and maint.mk files are taken from the
	GNULIB project, unchanged

	The cfg.mk file is used to configure which of the syntax checks
	are activated, to allow addition of new project specific syntax
	checks, and to blacklist certain files which should not be checked

	Fix up copyright decl to always use 'Copyright (C) Red Hat, Inc.'
	A couple of files were missing '(C)' in the copyright header

	Improve usefulness of README file
	The COPYING file already contains the license text, so the README
	file need not repeat it. Instead put in a description of what
	SPICE is, simple install instructions & pointers to mailing lists
	and bug trackers

	Fill out the AUTHORS file with some content
	The AUTHORS file is empty, fill it in with a list of present and
	past maintainers, and email addresses of all people who have
	contributed patches

	Remove casts from void * with xrealloc() calls
	The xrealloc() function returns void*, so the return value
	never needs to be cast

	Rewrite code to avoid triggering warning about casting param to free()
	Since free() takes a void* parameters do not need to be cast.

	The existing code here is actally fine, but it trips up the
	syntax-check rule, so tweak it to an equivalent construct
	which passes the syntax check

	Remove useless if() before free()
	The free() function allows NULL to be passed in, so any
	code which puts a if() before free() is wasting time

	Death to all TABs

	spicevmc: Fix assert when still connected on session disconnect (fdo#43903)
	Currently when the main channel disconnects while a spicevmc channel
	(such as a usbredir channel) is still connected, qemu will abort with the
	following message:
	ring_remove: ASSERT item->next != NULL && item->prev != NULL failed

	This is caused by red_client_destroy() first calling:
	rcc->channel->client_cbs.disconnect(rcc);
	And then calling:
	red_channel_client_destroy(rcc);

	For each channel. This is fine, but the spicevmc disconnect code does a
	red_channel_client_destroy(rcc) itself since as usb devices are added
	/ removed, the channels carrying their traffic get connected / disconnected
	and they get re-used for new devices, which won't work if the old channel is
	still there when the new connection comes in.

	This patch fixes the double destroy when there are still spicevmc channels
	connected by not doing the red_channel_client_destroy from the spicevmc
	disconnect code when not just the channel, but the entire client is
	disconnecting.

	server/spice-server.syms: fix 0.8 compatibility
	spice_server_migrate_connect is in 0.8.3 in the released 0.8 branch,
	and so should not be changed in 0.10. This doesn't break the 0.9.1
	release which didn't contain this symbol at all, only 0.9.2 release
	that hopefully no one actually packaged.

	server/red_worker: reuse dispatcher
	This patch reuses Dispatcher in RedDispatcher. It adds two helpers
	to red_worker to keep RedWorker opaque to the outside. The dispatcher is
	abused in three places that use the underlying socket directly:
	 once sending a READY after red_init completes
	 once for each channel creation, replying with the RedChannel instance
	  for cursor and display.

	FDO Bugzilla: 42463

	rfc->v1:
	* move callbacks to red_worker.c including registration (Yonit)
	* rename dispatcher to red_dispatcher in red_worker.c and red_dispatcher.c
	* add accessor red_dispatcher_get_dispatcher
	* s/dispatcher_handle_recv/dispatcher_handle_recv_read/ and change sig to
	  just Dispatcher *dispatcher (was the SpiceCoreInterface one)
	* remove SpiceCoreInterface parameter from dispatcher_init (Yonit)
	* main_dispatcher needed it for channel_event so it has it in
	  struct MainDispatcher
	* add dispatcher_get_recv_fd for red_worker

	server/dispatcher: add dispatcher_register_async_done_callback

	introduce DISPATCHER_{NONE,ACK,ASYNC}

	server: introduce dispatcher
	used for main_dispatcher only in this patch.

	Dispatcher is meant to be used for Main<->any low frequency messages.

	It's interface is meant to include the red_dispatcher usage:
	 fixed size messages per message type
	 some messages require an ack

	Some methods are added to be used by RedDispatcher later:
	 dispatcher_handle_read - to be called directly by RedDispatcher epoll
	  based loop
	 dispatcher_set_opaque - to be set from red_worker pthread
	 dispatcher_init - allow NULL core as used by red_worker

	Read and Write behavior:
	 Sender: blocking write, blocking read for ack (if any).
	 Reader: poll for any data, if such then blocking read for a
	 message_type and following message. repeat until poll returns
	 with no pending data to read.

	(3) spice_server_migrate_end: tell client migration it can switch to the target - send

	---------------------
	(1) the server identifies itself as a migraiton target since the client is linked with (connection_id != 0)

	client/x11: reset screen positions in XMonitor::do_restore
	XMonitor::do_restore (called for example when going out of
	fullscreen) restore the screen resolution to its previous state,
	but it doesn't take care of repositioning the screen to their
	previous position, which is one of the advantages of using randr
	1.2.
	Since MultyMonScreen::restore handles all of this for us, just call
	it to restore the monitor position/resolutions to their previous
	settings. Before doing any changes, MultyMonScreen::restore checks
	if there's something to do, so calling it once per monitor won't be
	an issue, the resolution/position will only be set the first time.

	This has the side-effect of fixing bug #693431. This bug occurs when
	closing the client after the client went in and out of fullscreen.
	MultyMonScreen::~MultyMonScreen calls MultyMonScreen::restore, which
	decides to change the screen positions since they were lost when going
	to fullscreen because XMonitor::restore didn't restore the positions.
	After this change, the positions will be properly restored and
	MultyMonScreen::restore won't be needlessly called upon client
	shutdown.

	client/x11: fix mode setting in MultyMonScreen::restore
	MultyMonScreen::restore changes the X11 Screen resolution, but it
	doesn't use MultyMonScreen::set_size. This means
	MultyMonScreen::_width and MultyMonScreen::_height don't get
	updated to reflect the new resolution settings, which could cause
	issues later on. Until now this was safe since the only caller of
	MultyMonScreen::restore was MultyMonScreen destructor.

	client: don't crash when booting a Xinerama setup
	In a Xinerama setup, when X starts up and creates one of the
	secondary screens, first a non-primary surface is created on the
	secondary screen, and then the primary surface for this screen is
	created.
	This causes a crash when the guest uses Xinerama and the client
	is attached to the VM before X starts (ie while the guest is
	booting).
	This happens because DisplayChannel::create_canvas (which is called
	when creating a non-primary surface) assumes a screen has already been
	set for the DisplayChannel while this only happens upon primary surface
	creation. However, it uses the screen for non important stuff, so we
	can test if screen() is non NULL before using it. This is what is done
	in other parts of this file.

	Since the glz dictionary is shared between all the

	happen that the glz dictionary code decides to free an image from one

	DisplayChannelClient), so the error message that is printed is not an
	actual error. This commit removes this message and adds a comment
	explaining what's going on.

	Rename usbredir channel code to spicevmc
	While discussing various things with Alon in Vancouver, it came up that
	having a channel which simply passes through data coming out of a qemu
	chardev frontend unmodified, like the usbredir channel does, can be used
	for a lot of other cases too. To facilitate this the usbredir channel code
	will be turned into a generic spicevmc channel, which is just a passthrough
	to the client, from the spicevmc chardev.

	This patch renames usbredir.c to spicevmc.c and changes the prefix of all
	functions / structs to match. This should make clear that the code is not
	usbredir specific.

	Some examples of why having a generic spicevmc pass through is good:
	1) We could add a monitor channel, allowing access to the qemu monitor from
	the spice client, since the monitor is a chardev frontend we could re-use
	the generic spicevmc channel server code, so all that is needed to add this
	(server side) would be reserving a new channel id for this.

	2) We could allow users to come up with new channels of their own, without
	requiring qemu or server modification. The idea is to allow doing something
	like this on the qemu startup cmdline:
	-chardev spicevmc,name=generic,channelid=128

	To ensure these new "generic" channels cannot conflict with newly added
	official types, they must start at the SPICE_CHANNEL_USER_DEFINED_START value
	(128).

	These new user defined channels could then either be used with a special
	modified client, with client plugins (if we add support for those), or
	by exporting them on the client side for use by an external ap, see below.

	3) We could also add support to the client to make user-defined channels
	end in a unix socket / pipe, allowing handling of the data by an external app,
	we could for example have a new spice client cmdline argument like this:
	--custom-channel unixsocket=/tmp/mysocket,channelid=128

	This would allow for something like:
	$random app on guest -> virtio-serial -> spicevmc chardev ->
	 -> spicevmc channel -> unix socket -> $random app on client

	4) On hind sight this could also have been used for the smartcard stuff,
	with a 1 channel / reader model, rather then the current multiplexing code
	where we've our own multiplexing protocol wrapper over the libcacard
	smartcard protocol.

	usbredir: Merge UsbRedirState and UsbRedirChannel
	Now that the Channel struct is gone and the RedChannel has the same lifetime
	as the chardev interface there is no need to have these 2 separate.

	server/red_worker: remove forced disconnect on connect

2011-08-23  Yonit Halperin  <yhalperi@redhat.com>

	server/red_worker.c: fix CursorPipeItem leak
	CursorPipeItems and their corresponding cursor_item were not
	freed when they were removed from the pipe without sending them.
	In addition cursor_channel_hold_pipe_item used wrong conversion
	to (CursorItem*) for a (CursorPipeItem*).

2011-08-23  Alon Levy  <alevy@redhat.com>

	server/red_worker: split cursor pipe item from cursor item
	Required to support multiple clients.
	Also changes somewhat the way we produce PIPE_ITEM_TYPE_LOCAL_CURSOR. Btw,
	I haven't managed to see when we actually produce such an item during my
	tests.

	Previously we had a single pipe item per CursorItem, this is impossible
	with two pipes, which happens when we have two clients.

	server/red_worker: whitespace fixes

	server/reds: add RedsState.allow_multiple_clients
	Currently set by environment variable SPICE_DEBUG_ALLOW_MC (any value means
	to allow multiple connections). Later will be set by spice api from qemu.

	server/red_channel: introduce client ring in RedChannel
	Also adds Drawable pipes and glz rings.

	main_channel and red_worker had several locations that still accessed rcc
	directly, so they had to be touched too, but the changes are minimal.

	Most changes are in red_channel: drop the single client reference in RedChannel
	and add a ring of channels.

	Things missing / not done right in red_worker:
	 * StreamAgents are in DCC - right/wrong?
	 * GlzDict is multiplied - multiple compressions.

	We still are missing:
	 * remove the disconnect calls on new connections

	server/red_channel: add pipe_size helpers

	server/red_worker: remove more direct access to RedChannelClient.rcc

2011-08-23  Yonit Halperin  <yhalperi@redhat.com>

	server/red_worker.c: make dictionary and cache different per client
	There is no inter-client shared dictionary and cache yet.

	At this point the display channel can be used by multiple clients.

	You can still crash on lack of Drawables or CursorItems due to the slower
	clients pipe growing uncontrollably.

2011-08-23  Alon Levy  <alevy@redhat.com>

	server/red_worker: multiple client support - base split
	This patch compiles but breaks spice.

	Split both display and cursor channels to a client part and channel part.

	Introduce DisplayChannelClient, CursorChannelClient, CommonChannelClient.
	don't disconnect channel on client disconnect.
	Move all caches to the ChannelClient's.

	Remove reference counting of the channel.

	No new functionality introduced.

	NOTE: Introduces a crash in disconnections, a regression, resulting from
	incorrect thread access, that is fixed in the patch titled:
	"server: registering RedChannel in reds, instead of Channel"

	server/red_worker: cleanup

	server/smartcard: support multiple clients
	each client supplying a smartcard channel gets it's own smartcard. If
	there are not enough smartcards provided by the server (read: qemu)
	then it will be as though there are none.

	currently disabled - later patches that enable smartcard don't make
	this channel available to any but the first client.

	server/red_tunnel_worker: trivial multi client support
	s/TunnelChannel/TunnelChannelClient/

	That's about it.  this is probably the wrong way to do it. Not tested
	at all. What do we want, a separate interface per client? same interface
	for all clients? probably the later. This doesn't do that. Not tested,
	so probably doesn't even work.

	changes red_channel_pipe_item_is_linked to red_channel_client_pipe_item_is_linked,
	since tunnel channel is the only user, must be done in patch to not break compilation.

	server/inputs_channel: support multiple clients
	from server events are broadcast - leds change. The rest is client
	to server, so it is just passed on.

	server/main_channel: support multiple clients
	The main channel deals with connecting new clients, announcing mouse mode
	changes, and the agent channel. The implementation is currently done without
	any changes to the protocol, so everything has to be either broadcast or
	to a specific client.

	 channels list - specific client
	 mouse mode - broadcast
	 agent - broadcast
	 notify - broadcast (should have two modes, and use the appropriate)

	Notable TODOs:
	 * migration testing
	 * agent tokens are wrongly sent (or did I fix that? check)

	server/red_channel: introduce pipes functions
	Introduce functions to add (via producer method) the same item to multiple
	pipes, all for the same channel.

	Note: Right now there is only a single channel, but the next patches will do the
	per-channel breakdown to channel and channel_client before actually introducing
	a ring in RedChannel, this makes it easier to make smaller changes - the
	channel->rcc link will exist until removed in the ring introducing patch.

	server/red_channel: ignore error if already shutdown
	on red_channel_peer_on_incoming_error, if we are already shutdown, do not
	call the channel's error handler. Since the channel has been shutdown, we
	assume this is a second or later error, and handling has already occured.

	server/main_channel: move connection_id from reds
	Expose additional api to find a client given a connection_id. The connection_id
	is first set when the first channel connects, which is the main channel.
	It could also be kept in the RedClient instead, not sure.

	TODO:
	 multiple todo's added for multiclient handling. I don't remember why
	 I wrote them exactly, and besides if I did any migration tests. So: TODO.

	server/main_channel: move ping here from reds.
	cleanup only. Note that the ping function is half used since the opt parameter
	stopped being called with anything but NULL, should be returned at some point,
	specifically when we drop the 250kbyte ping on start and do a continuous check
	for latency and bandwidth.

	See:
	 81945d897 - server: add new vd interface QTerm2Interface, Yaniv Kamay
	  introducing the usage of ping with a non NULL opt
	 3f7ea8e7a - zap qterm interfaces, Gerd Hoffman
	  removing it

	server/main_channel: move latency and bitrate to channel client
	They were globals before. This introduces api for other channels
	to query the low bandwidth status. The queries themselves are still done
	from the wrong context (channel and not channel client) but that's because
	the decoupling of channel and channel client will be done in the following
	patches.

	Note that snd_worker.c got two copied function declarations that belong to
	main_channel.h but can't be easily dragged into snd_worker.c since it still
	uses it's own RedChannel struct.

	server/reds: add concept of secondary channels
	Secondary channels are those that don't support multiple clients. The
	support added in this patch just doesn't let the second or more connected
	client receive the unsupported channels in the channels list sent by the
	server to the client. This doesn't handle the situation where:

	client A connects (gets all channels)
	client B connects (gets supported multiple client channels)
	client A disconnects (Suboptimal 1: B doesn't get new channels at this point)
	client C connects (Suboptimal 2: C doesn't get the full list of channels, but
	the partial one)

	Specifically the channels that only support a single client are:
	 sound (both playback and record channels)
	 smartcard
	 tunnel

	server: Add RedClient
	That means RedClient tracks a ring of channels. Right now there will be only
	a single client because of the disconnection mechanism - whenever a new
	client comes we disconnect all existing clients. But this patch adds already
	a ring of clients to reds.c (stored in RedServer).

	There is a known problem handling many connections and disconnections at the
	same time, trigerrable easily by the following script:

	export NEW_DISPLAY=:3.0

	Xephyr $NEW_DISPLAY -noreset &
	for ((i = 0 ; i < 5; ++i)); do
	    for ((j = 0 ; j < 10; ++j)); do
	        DISPLAY=$NEW_DISPLAY c_win7x86_qxl_tests &
	    done
	    sleep 2;
	done

	I fixed a few of the problems resulting from this in the same patch. This
	required already introducing a few other changes:
	 * make sure all removal of channels happens in the main thread, for that
	 two additional dispatcher calls are added to remove a specific channel
	 client (RED_WORKER_MESSAGE_CURSOR_DISCONNECT_CLIENT and
	 RED_WORKER_MESSAGE_DISPLAY_DISCONNECT_CLIENT).
	 * change some asserts in input channel.
	 * make main channel disconnect not recursive
	 * introduce disconnect call back to red_channel_create_parser

	The remaining abort is from a double free in the main channel, still can't
	find it (doesn't happen when running under valgrind - probably due to the
	slowness resulting from that), but is easy to see when running under gdb.

	server/main_channel+reds: make main_channel_init return MainChannelClient
	This makes it easier to introduce RedClient in the next patch.

	server/red_worker: release PIPE_ITEM_TYPE_VERB in display channel
	We send a SPICE_MSG_DISPLAY_MARK verb.

	server/red_client: clear pipe on disconnect

	server/red_channel: workaround for fast client disconnect bug (TODO - real fix)

	server/main_channel: use MainChannel in sig
	use MainChannel* instead of Channel* for a many functions in main_channel.h
	(affects main_channel.c and reds.c).

	some one liner fixes are hidden in here too.

	server: move pipe from RedChannel to RedChannelClient
	Another cleanup patch, no change to behavior (still one client, and it
	disconnects previous client if any).

	The implementation for multiple client is straightforward: the pipe
	remains per (channel,client) pair, so it needs to move from the RedChannel
	that to RedChannelClient. Implementation using a single pipe with multiple
	consumers (to reflect different latencies) doesn't fit well with pipe rewriting
	that is used by the display channel. Additionally this approach is much simpler
	to verify. Lastly it doesn't add considerable overhead (but see the display
	channel changes in a later patch for a real place to rethink).

	This patch is just technical, changing signatures to reflect the first
	argument (oop style) so red_channel becomes red_channel_client. Some places
	may seem odd but they should be fixed with later comits where the channels
	grow to support multiple clients.

	Sound (playback/record) channels are the only ones not touched - this is
	consistent with previous patches, since they have been left out of the
	RedChannel refactoring.  That is left as future work. (note that they don't use
	a pipe, which was the reason for not refactoring).

	server/red_worker: introduce {display,cursor}_is_connected
	Instead of checking for worker->{display,cursor}_channel directly.

	server/red_channel (all): introduce RedChannelClient
	This commit adds a RedChannelClient that now owns the stream connection,
	but still doesn't own the pipe. There is only a single RCC per RC
	right now (and RC still means RedChannel, RedClient will be introduced
	later). All internal api changes are in server/red_channel.h, hence
	the need to update all channels. red_worker.c is affected the most because
	it makes use of direct access to some of RedChannel still.

	API changes:

	 1. red_channel_client_create added.
	  rec_channel_create -> (red_channel_create, red_channel_client_create)
	 2. two way connection: rcc->channel, channel->rcc (later channel will
	  hold a list, and there will be a RedClient to hold the list of channels
	  per client)
	 3. seperation of channel disconnect and channel_client_disconnect

	TODO:
	 usbredir added untested.

	server/red_worker: drop red_pipe_add_tail, use red_channel_pipe_add_tail
	The only difference between them being that the later also does a push.
	I don't believe that to be a problem, but if it does I can always introduce
	a push'less version.

	server/red_channel: renames to use _proc postfix consistently
	rename types - we use _proc suffix mostly to indicate function pointer types,
	use it for some function pointers that were missing it.

	s/channel_handle_migrate_flush_mark/channel_handle_migrate_flush_mark_proc/

	common: introduce red_printf_debug

	server/tests/test_playback: correctly use spice_server_playback_get_buffer
	and spice_server_playback_put_samples. The former retrieves a buffer from a free
	list with spice_server_playback_get_buffer, and should be used once via
	spice_server_playback_put_samples. The tester previously reused the same buffer
	a number of times.

	server/tests/basic_event_loop: multiple fixes
	reuse common/ring.h
	ignore SIGPIPE
	fix handling of removed watches

	tests/migrate.py: add --vdagent
	Adds the required options to provide a vdagent to the guest in both source and target qemu
	instances.

	This will be the last update of the in spice git tests directory, I've moved those tests
	to the repository spice-tests. The longer term goal remains autotest integration, but since
	this test (and some minor others for qemu) need a home it is:

	http://cgit.freedesktop.org/~alon/spice-tests/

	(I'm reluctant to put it under spice/ because of my wish to go to autotest, but still, there
	they are. Nothing as permanent as the temporary).

	Independent (of external modules, i.e. qemu) tests (server/tests) should remain in tree.

	use Xkb to get keyboard modifier mask
	To be able to enable/disable keyboard leds on X11, we need to query
	the X server for which mask correspond to which led (NumLock,
	CapsLock). So far this was done using XKeysymToKeycode and iterating
	over X modifier mapping.
	Xkb provides XkbKeysymToModifiers for this purpose, and since
	we're using Xkb anyway, it makes more sense to use it.

	At some point, on my Fedora 15 box, XKeysymToKeycode was returning
	NoSymbol for CapsLock and NumLock leading to spicec not being able
	to change the keyboard leds when qemu tells it to. However, I couldn't
	reproduce this when I tried again :-/

	fix harmless typo in InputsChannel::handle_modifiers
	InputsChannel::handle_modifiers converts _modifiers which is a
	bitflag of SPICE_KEYBOARD_MODIFIER_FLAGS_* to a Platform::*_MODIFIER
	bitflag, which is what Platform::set_keyboard_lock_modifiers expects.
	However, it's called with _modifiers, and the bitflag that this
	function computes is never used. Pass the computed bitflag to
	::set_keyboard_lock_modifiers since _modifiers format is meaningless
	for ::set_keyboard_lock_modifiers.
	This bug was harmless because the two different set of modifier
	flags actually use the same values, so _modifiers and modifiers could
	be used interchangeably. However it's more future-proof to use the
	right format here.

	mjpeg: fix libjpeg assertion
	After the changes to add libjpeg-turbo support to spice-server mjpeg
	compression code, it's relatively easy to hit an assertion from
	libjpeg in spice-server about "too few scanlines transferred" when
	the mjpeg streaming code triggers. This assertion brings down qemu,
	which is bad :)

	This is because when we first initialize the mjpeg encoder, we do:

	stream_width = SPICE_ALIGN(src_rect->right - src_rect->left, 2);
	stream_height = SPICE_ALIGN(src_rect->bottom - src_rect->top, 2);

	stream->mjpeg_encoder = mjpeg_encoder_new(stream_width, stream_height);

	and then when we iterate over the image scanlines to feed them to
	libjpeg, we do:

	const int image_height = src->bottom - src->top;
	const int image_width = src->right - src->left;

	for (i = 0; i < image_height; i++) {
	    mjpeg_encoder_encode_scanline(...);
	}
	mjpeg_encoder_end_frame(...);

	When stream_height is odd, the mjpeg_encoder will be created with
	an height that is 1 more than the number of lines we encode. Then
	libjpeg asserts when we tell it we're done with the compression
	while it's still waiting for one more scanline.

	Looking through git history, this rounding seems to be an artifact
	from when we were using ffmpeg for the mjpeg encoding. Since
	spicec and spicy (the latter needs a few fixes) can handle streams
	with odd height/width, the best way to solve this issue is to stop
	rounding up the height and width of the streams we create. This
	even saves some bandwidth :)

	server/red_dispatcher: fix wrong resolution set for tablet
	when changing resolutions due to the new async code paths the surface
	creation command was kept by reference, and later, when the red_worker
	signaled completion by calling async_complete the mouse mode was updated
	using the reference. This caused the wrong values to be read resulting in wrong
	resolutions set and a non working mouse pointer. Fix this by keeping a copy of
	the surface creation command instead of a reference.

	No bz. Found in testing.

2011-07-31  Christophe Fergeau  <cfergeau@redhat.com>

	client: fix 30s timeout regression
	Changelog from Arnon Gilboa, patch from me:

	Commit eb6f55409412 caused the following regression:

	When client runs without the auto-conf or disable-effects options
	(either from CLI or controller), which is the case when using Spice
	from Admin Portal, the client will unecessarily wait for 30sec before
	connecting to a Windows guest with an agent running (this won't happen
	with linux guests or without an agent running).

	The mentioned patch assumed that on_agent_reply() of
	VD_AGENT_DISPLAY_CONFIG will call send_main_attach_channels() and
	connect. However, when auto-conf or disable-effects are not used,
	on_agent_reply() will ignore the reply and not call
	send_main_attach_channels(). Therefore, send_main_attach_channels()
	will only be called on agent timeout.

	The solution is to activate agent timer only if auto-conf or
	disable-effects. Otherwise, simply call send_main_attach_channels().

	Fixes rhbz #726441

	mjpeg: rename jpeg_mem_dest
	jpeg_mem_dest is a public symbol in libjpeg8 so using it with
	no prefix will cause symbol clashes. Rename it to spice_jpeg_mem_dest.

	mjpeg_encoder: allocate "row" on demand
	It's not used when we use jpeg-turbo colorspaces, so it's better
	to allocate it when we know we'll need it rather than always
	allocating it even if it won't be used.

	mjpeg_encoder: remove unused functions
	After the refactoring to optionally use libjpeg-turbo, some
	of the functions that mjpeg-encoder used to provide are now no
	longer used. This commit removes them.

	mjpeg_encoder: use libjpeg-turbo extra colorspaces
	When libjpeg-turbo is available, we can use the BGR and BGRX
	colorspaces that it provides to avoid extra conversions of the
	data we want to compress to mjpeg

	red_worker: use new mjpeg_encoder_encode_scanline API
	The main point is to move the pixel conversion code into
	the MjpegEncoder class to be able to make use libjpeg-turbo
	additional pixel formats without the reds_worker code noticing.

	mjpeg_encoder: add mjpeg_encoder_get_bytes_per_pixel
	Returns the number of bytes per pixel corresponding to the input
	data format.

	mjpeg_encoder: add mjpeg_encoder_encode_scanline
	This API is meant to allow us to move the pixel format conversion
	into MjpegEncoder. This will allow us to be able to use the
	additional pixel formats from libjpeg-turbo when available.

	red_worker: simplify red_rgb_to_24bpp prototype
	It takes a lot of arguments, "id" is unused, "frame" and
	"frame_size" can be obtained from the "stream" argument, so
	can get rid of 3 arguments to make things more readable.

	mjpeg_encoder: rework output buffer allocation
	When encoding a frame, red_worker passes an allocated buffer to
	libjpeg where it should encode the frame. When it fails, a new
	bigger buffer is allocated and the encoding is restarted from
	scratch. However, it's possible to use libjpeg to realloc this
	buffer if it gets too small during the encoding process. Make use
	of this feature, especially since it will make it easier to encore
	one line at a time instead of a full frame in subsequent commits.

	red_worker: factor pixel conversion code
	When encoding to mjpeg, the on screen data have to be converted
	to 24bpp RGB since that's the format that libjpeg expects. Factor
	as much code as possible for the 3 formats we handle.

	client: don't die if initial agent timeout triggers
	When the client connects to a spice VM, if an agent is detected,

	This commit changes this and lets the client connects to the
	guest when the timeout happens.

	client: only send one SPICE_MSGC_MAIN_ATTACH_CHANNELS messages
	492f7a9b fixed unwanted timeouts during initial client startup,

	was sent multiple times, once in RedClient::handle_init, then
	once again in RedClient::on_agent_announce_capabilities (which
	can even be triggered multiple times). Sending this message multiple
	times is a big NO and causes the server to close the client connection,
	and the client to die. Add a _msg_attach_message_sent boolean to
	make sure we only send this message once.

	server: make sure we clear vdagent and update mouse mode on agent disconnect
	The check this patch removes causes us to not set vdagent to NULL, nor
	update the mouse mode when the guest agent disconnects when no client is
	attached. Which leads to a non working mouse, and on agent reconnect a
	"spice_server_char_device_add_interface: vdagent already attached" message
	instead of a successful re-add of the agent interface .

	hansg: Note this is commit 443994ba from the 0.8 branch, which I did

	spicec: Make loglevel configurable through the environment
	Having a loglevel variable is much more useful if we can actually change
	its value without a recompile. Use a SPICEC_LOG_LEVEL environment variable so
	we can do this from the spice xpi / activex too (by setting the environment
	variable before starting the browser).

	server/red_worker: send surface images to client on-demand after S3/4 wakeup

	server/spice.h: bump QXL_MINOR because of QXLWorker and QXLInterface changes

	server: add QXLWorker.flush_surfaces_async for S3/S4 support
	This does the following, all to remove any referenced memory on the pci bars:
	    flush_all_qxl_commands(worker);
	    flush_all_surfaces(worker);
	    red_wait_outgoing_item((RedChannel *)worker->display_channel);
	    red_wait_outgoing_item((RedChannel *)worker->cursor_channel);

	The added api is specifically async, i.e. it calls async_complete
	when done.

	server: add QXLInterface::update_area_complete callback
	when update_area_async is called update_area_complete will be called with
	the surfaces dirty rectangle list.

	server/red_worker: handle_dev_input: reuse write_ready introduced for async

	server: add async io support
	The new _ASYNC io's in qxl_dev listed at the end get six new api
	functions, and an additional callback function "async_complete". When
	the async version of a specific io is used, completion is notified by
	calling async_complete, and no READY message is written or expected by
	the dispatcher.

	update_area has been changed to push QXLRects to the worker thread, where
	the conversion to SpiceRect takes place.

	A cookie has been added to each async call to QXLWorker, and is passed back via
	async_complete.

	Added api:

	QXLWorker:
	    update_area_async
	    add_memslot_async
	    destroy_surfaces_async
	    destroy_primary_surface_async
	    create_primary_surface_async
	    destroy_surface_wait_async

	QXLInterface:
	    async_complete

	bump required spice-protocol to 0.8.1 for qxl_dev async and s3 updates

	server: api: add spice_qxl_* calls based on QXLWorker contents
	For each callback in QXLWorker, for example QXLWorker::update_area, add
	a direct call named spice_qxl_update_area.

	This will (a) remove the pointless indirection and (b) make shared
	library versioning alot easier as we'll get new linker symbols which
	we can tag with the version they appeared in the shared library.

	server: spice-server.syms: move sasl symbols to 0.8.2

	server/red_worker: remove print on handle_dev_destroy_surfaces

	server/red_worker: *_release_item: less frequent debug messages

	server: add symbol versioning to the spice server shared library.
	This patch adds symbol versions to the spice server library.  Each
	symbol which is exported by libspice-server gets tagged with the
	(stable) version where it appeared first.  This way the linker and rpm
	are able to figure which version of the spice-server libary is required
	by a particular qemu binary/package.

	remove unused function

	client: add missing "," in option list
	In commit 44073d1b38e2 - client: improve WAN option description
	one "," was missing at the end of the line. Since the next argument
	was a string too, gcc silently concatenated them, and thanks to C++
	polymorphic functions, the compiler didn't complain about the
	missing argument, so it went unnoticed.
	The effects are pretty bad though, since it prevents spicec from
	running because it thinks command line parsing fails.

2011-07-18  Christophe Fergeau  <cfergeau@redhat.com>

	Fix spice-server/qemu channel version checks
	When qemu creates a channel, reds.c contains code to check the
	minor/major channel versions known to QEMU (ie the ones that were
	current in spice-server when QEMU was compiled) and to compare these
	versions against the current ones the currently installed spice-server
	version.

	According to kraxel [1], the rules for these interface numbers are:

	"The purpose of the versions is exactly to avoid the need for a new
	soname.  The rules are basically:

	   (1) You add stuff to the interface, strictly append-only to not break
	       binary compatibility.
	   (2) You bump the minor version of the interface.
	   (3) You check the minor version at runtime to figure whenever the
	       added fields contain valid stuff or not.

	An example is here (core interface, minor goes from 2 to 3, new
	channel_event callback):

	http://cgit.freedesktop.org/spice/spice/commit/?id=97f33fa86aa6edd25111b173dc0d9599ac29f879
	"

	The code currently refuses to create a channel if QEMU minor version is
	less than the current spice-server version. This does not correspond
	to the intended behaviour, this patch changes to fail is qemu was compiled
	with a spice-server that is *newer* than the one currently installed. This
	case is something we cannot support nicely.

	client: rename connect_unsecure to connect_to_peer
	Both connect_secure() and connect_unsecure() call connect_to_peer().

	Prior to this commit spicec.log reported all connections as unsecure,
	as connect_secure() called connect_unsecure() to make the connection.
	This fixes RH bug #653545

2011-07-18  Christophe Fergeau  <cfergeau@redhat.com>

	client: don't crash when agent is missing WAN support
	If you try to connect to a linux guest with WAN options, SPICE window opens up
	and is blank - it then fails with vdagent timeout message.  It should give a
	warning that this is only applicable for windows guest and still connect to
	guest.

	It all starts in RedClient::handle_init
	This function checks whether we have an agent or not, because if we have an
	agent, there will be some kind of handshake to check both sides capabilities
	before all the spice channels are created.

	When there is no agent running, the startup process goes on with
	SPICE_MSGC_MAIN_ATTACH_CHANNELS

	When there is a windows agent running, VD_AGENT_ANNOUNCE_CAPABILITIES and
	VD_AGENT_DISPLAY_CONFIG messages are sent to the agent, and when processing the
	agent answer to the VD_AGENT_DISPLAY_CONFIG message,
	SPICE_MSGC_MAIN_ATTACH_CHANNELS will be sent and the startup process will go
	on.

	However, when there is no agent running but --color-depth was used, handle_init
	won't send the SPICE_MSGC_MAIN_ATTACH_CHANNELS message but will wait for the
	agent handshake to proceed to its end, which won't happen, so it will timeout
	waiting for agent answers.

	Similarly, the linux agent handles VD_AGENT_ANNOUNCE_CAPABILITIES messages, but
	it doesn't handle VD_AGENT_DISPLAY_CONFIG messages, so we'll never reach the
	point where a SPICE_MSGC_MAIN_ATTACH_CHANNELS will be sent.

	This commit fixes this in 2 places:
	- unconditionnally send SPICE_MSGC_ATTACH_CHANNELS when no agent is running in
	handle_init
	- send SPICE_MSGC_MAIN_ATTACH_CHANNELS in
	RedClient::on_agent_announce_capabilities if the agent doesn't have the
	VD_AGENT_CAP_DISPLAY_CONFIG capability

	This fixes RH bug #712938

	client: improve WAN option description
	The WAN options (--color-depth and --disable-effects) need
	support from the guest agent to be working. Currently they are
	only supported on Windows. While I don't want to explicitly
	mention Windows in --help output, we can hint that it won't
	work with all guests in --help. This fixes RH bug #712941

	x11: don't return freed memory from get_clipboard
	There is a double free in client/x11/platform.cpp.
	In get_selection(), in the exit: case with ret_val == -1 and data != NULL,
	*data_ret (which is returned to the caller) has already been
	assigned "data", so it will be pointing to freed memory when "data" is
	XFree'd'. Then in handle_selection_notify, get_selection_free is called on
	this pointer, which causes a double free.
	When the length of the read data = 0, set the returned value to NULL,
	this way subsequent free attempts will be a noop.
	Fixes RH bug #710461

	client: match delete[] with new[]
	vinfo in x11/platform.cpp is allocated using new[] so it needs to
	be freed with delete[]

	server: add missing calls to red_handle_drawable_surfaces_client_synced
	red_handle_drawable_surfaces_client_synced was called only from red_pipe_add_drawable, while it
	should also be called from red_pipe_add_drawable_after. Otherwise, the client
	might receive a command with a reference to a surface it doesn't hold and crash.

	server: fix access to a released drawable. RHBZ #713474
	red_pipe_add_drawable can lead to removal of drawables from current tree
	(since it calls red_handle_drawable_surfaces_client_synced), which can
	also lead to releasing these drawables.
	Before the fix, red_current_add_equal, called red_pipe_add_drawable,
	without assuring afterwards that the drawables it refers to are still alive or
	still in the current tree.

	server: fix segfault if no migrate_info provided
	qemu calls spice_server_migrate_switch even if it didn't do a

	marshalling code just in case.

	server: cursor_channel: releasing pipe items resources when the pipe is cleared (on disconnect)
	same as commit 74a9d10af96f4d7c8c1b1d7fca124a8df9180787 for cursor channel

	server: display_channel: releasing pipe items resources when the pipe is cleared (on disconnect)
	fixes "display_channel_release_item: panic: invalid item type"

	Before changing the red_worker to use the red_channel interface, there
	was a devoted red_pipe_clear routine for the display channel and cursor channel.
	However, clearing the pipe in red_channel, uses the release_item callback
	the worker provided. This callback has handled only resources that need to be released
	after the pipe item was enqueued from the pipe, and only for pipe items that were set in
	red_channel_init_send_data.
	This fix changes the display channel release_item callback to handle all types of
	pipe items, and also handles differently pushed and non-pushed pipe items.

	server: not reading command rings before RED_WORKER_MESSAGE_START, RHBZ #718713
	On migration, destroy_surfaces is called from qxl (qxl_hard_reset), before the device was loaded (on destination).
	handle_dev_destroy_surfaces led to red_process_commands, which read the qxl command ring
	(which appeared to be not empty), and then when processing the command
	it accessed unmapped memory.

	server: replace redundant code with red_cursor_reset
	In addition (1) make handle_dev_destroy_surfaces call red_release_cursor
	(2) call red_wait_outgoing_item(cursor_channel) only after adding msgs to pipe

	server: removing local cursor, this solves RHBZ #714801
	When the worker was stoped, the cursor was copied from guest ram to the host ram,
	and its corresponding qxl command was released.
	This is unecessary, since the qxl ram still exists (we keep references
	to the surfaces in the same manner).
	It also led to BSOD on guest upon migration: the device tracks cursor set commands and it stores
	a reference to the last one. Then, it replays it to the destination server when migrating to it.
	However, the command the qxl replayed has already been released from the pci by the original
	worker, upon STOP.

	client: fix for redundant shift+f11 RHBZ #674532
	After shift+F11, both in Windows 7 and xp clients, WM_KEYUP events were missing for
	SHIFT and F11. For F11 it was less important since unpress_all was preformed for all keys.
	However, we perform sync for all the keyboard modifiers and the GetKeyboardState returns "down" for shift.
	In windows7 client, we sometimes received afterwards a F11 KEYDOWN event repetition, and this caused SHIFT+F11 to be called again.
	Not performing hiding of the windows while changing client resolutions, solved the problem of missing events, and I don't see any difference
	in how spice looks while toggling to full screen.
	Using GetAsyncKeyState, returns "UP" for shift in windows 7, and helps avoid performing shift+f11 again, if there is an F11 repetition
	before we receive the KEYUP event for shift.

	remove void * arithmetic

	SW_CANVAS_NO_CHUNKS isn't used anywhere but in this file.
	SW_CANVAS_CACHE is now defined directly in the files where it's

	add comment to beginning of autogenerated files

	s/USE_OGL/USE_OPENGL
	This is more explicit about what it does, and not much longer

	use AC_DEFINE instead of hardcoding preprocessor flags
	Now that all source files include config.h, we can use AC_DEFINE
	to enable/disable optional features (opengl, cegui). This is
	cleaner than directly appending -Dxxx directives to the preprocessor
	flags. This also guarantees that everything will be appropriately
	rebuilt when using the same source tree to build first with opengl
	support and then without (the config.h timestamp will change,
	triggering a rebuild of the files including it)

	add config.h to autogenerated files too
	Modify the python (de)marshaller generator to add #include
	<config.h> at the beginning of the C files it generates

	add #include <config.h> to all source files
	When using config.h, it must be the very first include in all source
	files since it contains #define that may change the compilation process
	(eg libc structure layout changes when it's used to enable large file
	support on 32 bit x86 archs). This commit adds it at the beginning
	of all .c and .cpp files

	autotools: correctly build canvas-related code
	spice client and spice server shares code from
	common/{gdi,gl,sw}_canvas.[ch]. However, while most of the code is
	shared, the server code wants a canvas compiled with
	SW_CANVAS_IMAGE_CACHE defined while the client code wants a canvas
	compiled with SW_CANVAS_CACHE.

	The initial autotools refactoring didn't take that into account,
	this is now fixed by this commit. After this commit, the canvas
	files from common/ are no longer compiled as part of the
	libspice-common.la convenience library. Instead, there are "proxy"
	canvas source files in client/ and server/ which #include the
	appropriate C files after defining the relevant #define for the
	binary that is being built.

	To prevent misuse of the canvas c files and headers in common/,
	SPICE_CANVAS_INTERNAL must be set when including the canvas headers
	from common/ or when building the c files from common/ otherwise
	the build will error out.

	configure.ac: remove unused AC_SUBST

	autotools: refactor the whole build machinery
	spice Makefile.am setup is a bit confusing, with source file
	names being listed several times in different Makefile.am
	(generally, once in EXTRA_DIST and another time in another
	Makefile.am in _SOURCES). The client binaries are built
	by client/x11/Makefile.am, which means recursing into client,
	then into x11 to finally build spicec. This Makefile.am is
	also referencing files from common/ and client/, which is
	a bit unusual with autotools.

	This patch attempts to simplify the build process to get
	something more usual from an autotools point of view.
	The source from common/ are compiled into a libtool convenience
	library, which the server and the client links against which avoids
	referencing source files from common/ when building the server and
	the client. The client is built in client/Makefile.am and directly
	builds files from x11/ windows/ and gui/ if needed (without
	recursing in these subdirectories).

	This makes the build simpler to understand, and also makes it
	possible to list source files once, which avoids potential
	make distcheck breakage when adding new files.

	There is a regression in this patch with respect to
	sw_canvas/gl_canvas/gdi_canvas. They should be built with
	different preprocessor #defines resulting in different behaviour
	of the canvas for the client and the server. However, this is not
	currently the case, both the client and the server will use the same
	code for now (which probably means one of them is broken). This will
	be fixed in a subsequent commit.

	make distcheck passes, but compilation on windows using the
	autotools build system hasn't been tested, which means it's likely
	to be broken. It shouldn't be too hard ot fix it though, just let
	me know of any issues with this.

	add missing "LGPLv2.1 or later" header to source files

	common: don't try to redefine PANIC if it already exists
	canvas_base.c tries to define PANIC, but it might already be set
	if eg client/debug.h has been included before. All the other
	macros in this file are guarded by #ifndef, this commit adds
	the missing #ifndef to PANIC. Note that this is just a bandaid,
	ideally common/ would contain a logging frameword, and these
	macros would only be defined once instead of being defined in
	several places.

	server: s/desable/disable
	This fixes a typo in some function names, there should be no
	functional change.

	use foo(void) instead of foo() in prototypes
	In C, the latter isn't a prototype for a function with no arg,
	but declares a function with an undefined number of args.

	server: remove extra arg in reds_on_main_agent_start call

	client: remove c++ wrappers
	client/ contains several .cpp file which only #include a .c file
	of the same name. This is unusual and seems to only be done to
	get C++ name mangling on the symbols defined in the C file.
	Now that all headers files in common/ use extern "C", these
	wrappers are no longer useful.

	common: add missing header guards to gl_canvas.h

	common: add extern "C" guards to headers
	Since some spice C++ code is using code from common/, the C
	functions need to be marked as such for the C++ compiler, otherwise
	we'll get linkage issues.

	client: make building client optional

	configure.ac: replace tab with spaces
	This makes the "C++ Compiler:     ...." status output nicely
	aligned with the other messages.

	configure.ac: remove unused dynamic linkage flag
	configure.ac defines a SPICEC_STATIC_LINKAGE_BDYNAMIC variable
	when --enable-static-linkage is not set, but it's never used.
	SPICEC_STATIC_LINKAGE_BSTATIC is used in client/, but since we
	are using libtool, it might be more appropriate to use
	'make LDFLAGS="-all-static"' to achieve static link.

	configure.ac: fix use of AC_ARG_ENABLE
	Most uses of AC_ARG_ENABLE were buggy:
	- when passing --disable-xxx, configure.ac would behave as if it
	  was passed --enable-xxx
	- passing --enable-xxx=foo would "leak" into the summary, ie the
	  summary (at the end of configure) would say "xxx: foo" instead
	  of "xxx: yes"

	This patch fixes these 2 issues.

	configure.ac: fix make dist

	server: use is_primary_surface
	red_worker.c has an is_primary_surface helper function, but there
	were some places in the file not using it. This patch fixes that

2011-04-18  Christophe Fergeau  <cfergeau@redhat.com>

	client: skip spaces in --host-subject
	This fixes fdo bug #32896:

	"Subject in certificates is stored in following format (values separated by
	comma and space):

	grep Subject: server-cert.pem | awk -F": " '{print $2}'
	O=REDHAT, CN=10.34.58.2

	While spicec expects that values in host subject are separated only by comma:

	spicec --host-subject "O=REDHAT,CN=10.34.58.2"
	"

	In this case, ignoring spaces make it much easier to directly copy and paste
	the subject line from certificates.

	draw: remove SPICE_ADDRESS
	This commit removes the typedef for SPICE_ADDRESS which was no
	longer used. This is the last thing that was missing to close
	fdo bug #28984

	client: add --version cmdline option to spicec
	This fixes freedesktop bug #33907

	client: s/reqired/required in CmdLineParser

	client: s/AVAILIBLE/AVAILABLE in CmdLineParser
	It was mispelt in a CmdLineParser enum.

	server/tests remove useless assignment
	This was detected by clang-static-analyzer.

	common/pixman: remove dead assignments
	They were detected using clang-static-analyzer. Don't initialize
	the variable to a value to override it with a different value
	a few lines after.

	tests: fix compilation with -Wall -Werror
	When compiling spice with make CFLAGS="-g3 -ggdb3 -O0 -Wall -Werror",
	the build broken because of a few unused variables/missing returns.
	This patch fixes these warnings.

	gl: remove unused variables
	gcc 4.6 warned about these.

	gl: use correct pixman accessor for image data
	Commit 774e5bd36f4 changed
	-  dest->source.pixmap.x_image->data +
	+  (uint8_t *)pixman_image_get_stride(dest->source.pixmap.pixman_image) +

	The correct accessor to use is pixman_image_get_data. Thanks to gcc
	4.6 for warning about a "different size" int to pointer conversion.

	client: use silent generation rules in Makefile.am
	The server Makefile.am rules for marshallers generation are
	prefixed with AM_V_SILENT to integrate nicely with automake silent
	rules. The same AM_V_SILENT prefix isn't used in client/Makefile.am
	resulting in verbose output even when automake silent mode is
	enabled. This commit removes this verbosity.

2011-04-04  Christophe Fergeau  <cfergeau@gmail.com>

	configure.ac: remove detection of WARN_UNUSED_RESULT
	spice configure.ac has some code to detect if the compiler has
	a special attribute to tag some functions so that they generate a
	warning when their return value isn't checked. However, this test
	is broken (the gcc attribute name is "warn_unused_result", not
	"__warn_unused_result__" and WARN_UNUSED_RESULT is unused anyway
	since spice-protocol provides SPICE_GNUC_WARN_UNUSED_RESULT. Thus
	we can just drop that block of code from configure.ac

2011-04-04  Hans de Goede  <hdegoede@redhat.com>

	server: make sure we clear vdagent and update mouse mode on agent disconnect
	The check this patch removes causes us to not set vdagent to NULL, nor
	update the mouse mode when the guest agent disconnects when no client is
	attached. Which leads to a non working mouse, and on agent reconnect a
	"spice_server_char_device_add_interface: vdagent already attached" message
	instead of a successful re-add of the agent interface .

	server: ignore SPICE_MSGC_MAIN_AGENT_START messages when there is no agent
	This can happen for example when a SPICE_MSGC_MAIN_AGENT_START message
	from the client and the vdagent disconnecting race.

	server: hookup agent-msg-filter discard-all functionality
	This ensures that if the client or agent connects to the client-agent
	"tunnel" while the other side is halfway through sending a multi part
	message, the rest of the message gets discarded, and the connecting
	party starts getting data at the beginning of the next message.

	server: add discard all option to agent message filter

	server: filter all data from client
	Filter all data from client, even when there is no agent connected
	to keep filter state correct.

	server: reset read/write filter on agent/client disconnect
	The agent message filter keeps track of messages as they are being send
	reset the relevant filter to its initial state when one of the 2 ends
	of the agent<->client "tunnel" disconnects.

	server: break read_from_vdi_port loop if the guest gets disconnected
	read_from_vdi_port calls dispatch_vdi_port data, which will disconnect
	the guest agent if it sends invalid data. It would then try to read more
	data from the disconnected guest agent resulting in a NULL ptr dereference,
	this patch fixes this.

	server: Don't stop writing agent data to the guest when the client disconnects
	write_to_vdi_port() was checking for reds->agent_state.connected to determine
	wether it could write queued data. But agent_state.connected reflects if
	*both* ends are connected. If the client has disconnected, but the guest agent
	is still connected and some data is still pending (like a final clipboard
	release from the client), then this data should be written to the guest agent.

	server: Don't reset agent state when the client disconnects
	We were calling reds_reset_vdp on client disconnect, which is not a good
	idea. reds_reset_vdp does 3 things:

	1) It resets the state related to reading chunks from the spicevmc virtio
	   port. If the client disconnects while the guest agent is in the middle
	   of sending a chunk, this will lead to an inconsistent state, and lots
	   of printing of "dispatch_vdi_port_data: invalid port" messages caused
	   by this inconsistent state sometimes followed by a segfault.

	   This can be triggered by copy and pasting something large (say
	   a screenshot) from the guest to the spice-gtk client, as the spice-gtk
	   client currently has a bug causing it to crash when receiving a multi
	   chunk vdagent messages. Without this patch (and with the spice-gtk bug
	   present) I can consistently reproduce this.

	2) It clears any buffered writes from the client to the guest still pending
	   because the virtio port cannot consume data fast enough. Since the agent
	   itself is still running fine, throwing away writes for it because the
	   client has disconnected makes no sense. Esp, since on clean exit the
	   client may very well send a clipboard release message directly
	   before closing the connection, and this may get lost this way.

	3) It sets client_agent_started to false, this is the only thing which
	   actually makes sense to do on client disconnect.

	Note that since we no longer reset the vdp state on client disconnect, we
	must now reset it on agent disconnect even if we don't have a client. So
	the reds_reset_vdp call in reds_agent_remove() gets moved to the top,
	above both the agent_state.connected and reds->peer checks which will
	both fail in the no client case.

2011-03-24  Hans de Goede  <hdegoede@redhat.com>

	server: avoid unneeded recursion in dispatch_vdi_port_data
	dispatch_vdi_port_data, was calling vdi_read_buf_release when no client
	is connected to free the passed in buf. The only difference between
	vdi_read_buf_release and directly adding the buffer back to the ring
	with ring_add, is that vdi_read_buf_release calls read_from_vdi_port
	after adding the buffer back. But dispatch_vdi_port_data only gets called
	from read_from_vdi_port itself, thus this would lead to recursing into
	read_from_vdi_port. read_from_vdi_port is protected against recursion and
	will immediately return if called recursively. Thus calling
	vdi_read_buf_release from dispatch_vdi_port_data is pointless, instead
	simply putting the buffer back in the ring suffices.

	server: Make copy paste support configurable
	Also bump SPICE_SERVER_VERSION to 0x000801 as 0.8.1 will be the
	first version with the new API for this, and we need to be able to
	detect the presence of this API in qemu.

	spicec-x11: Work around a bug in xsel
	Although ICCCM 2.2. Responsibilities of the Selection Owner:
	http://tronche.com/gui/x/icccm/sec-2.html#s-2.2

	Clearly states (about selection notify events):
	The owner should set the specified selection, target, time, and property
	arguments to the values received in the SelectionRequest event.

	xsel sets the selection notify event target member to the incr atom when it
	is going to send the clipboard data incremental, rather then setting it to
	the UTF8_STRING atom (which was the target of the SelectionRequest).

	Work around this (esp as it is likely other programs may get this wrong too)
	and accept the incr atom as a valid target in a selection notify event.

	This fixes Alon's test with running:
	python -c "print list(range(1000))" | xsel -i -b
	on the client.

	spicec-x11: Don't crash on apps sending bad atoms as TARGETS

	client: Don't handle hotkeys while sticky alt is active
	In some cases rhev-m changes the hotkey for releasing the mouse grab
	to ctrl + alt. This makes it impossible to send ctrl + alt + other-key
	to the guest, even when using sticky alt.

	What happens is:
	-press alt until sticky alt activates
	-release alt (but recorded state stays pressed due to sticky alt)
	-press ctrl
	-hotkey code sees ctrl+alt pressed, releases mouse grab
	-mouse grab release code does an unpress all -> end of sticky state.

	This patch makes it possible to atleast send ctrl + alt + del (or other key)
	using sticky alt. Note: even with this patch it is still a bad idea to
	use ctrl + alt as hotkey combi.

2011-03-08  Alon Levy  <alevy@redhat.com>

	server/reds: allow call to reds_agent_remove even if it is gone
	The current assert(reds->agent_state.connected) tiggers if when
	the agent disconnected there was still data waiting to be sent (for
	instance if there is a bug in the client handling clipboard and it
	is killed while a large clipboard transfer is in progress). So first
	call to reds_agent_remove happens from spice_server_char_device_remove_interface,
	and then it is called again (triggering the assert) from free_item_data
	from read_from_vdi_port because of the channel destruction.

	Other option would be to not call it from one of the paths - but that
	is suboptimal:
	 * if there is no data in the pipe, the second call never happens.
	 * the second call has to be there anyway, because it may fail during
	  parsing data from the agent.

	This patch fixes a segfault on this assert when a client starts passing
	from guest agent to client a large clipboard and dies in the middle. There
	is still another assert happening occasionally at marshaller which I don't
	have a fix for (but it doesn't seem to be related).

	server/input: avoid double free() of RedChannel on disconnect
	Current master is calling red_channel_destroy() on incoming error, but
	reds Channels still references it, which causes a double free() later
	on (see valgrind report below).

	Instead, on error condition, do like the rest of the channels and call
	reds_disconnect(), which remove the references and call shutdown(),
	which then call red_channel_destroy() and finally free the channel
	with red_channel_destroy().

	Note: the previous code intention was certainly to be able to keep the
	rest of the channels connected when input channel has errors. This is
	not addressed by this patch.

	server/red_channel: split Incoming/Outgoing to callback and state
	This allows later to have the callback table under RedChannel when
	the callbacks actually get used by RedChannelClient. Since the cb's
	are identical for different clients of the same channel it makes sense
	to store the callback pointers in one place per channel. The rest of
	the incoming and outgoing struct just gets moved to RedChannelClient.

	server/red_channel: no opaque in red_channel_peer_on_*_error

	server/red_worker: use red_channel_is_connected

	server/red_channel: add red_channel_disconnect, use in red_worker

	server/red_worker: complete removal of send_data.marshaller use

	server/red_worker: replace _send_ functions by _marshall_
	Changes in display channel for a code size win.

	A note about this and the previous cursor change: it will appear that we are
	now (with these changes) releasing resources too early. This is not so - send
	always has the option of blocking, which means after send you can not release
	resources anyway, that's what the release_item callback is for. So both the
	code before and now are doing the same accounting.

	server/red_channel: add red_channel_send_message_pending

	server/red_channel: add red_channel_all_blocked

	server/red_worker: cursor channel: replace _send_ with _marshall_

	server/red_channel (all): add red_channel_get_header
	This is useful during the channel specific channel_send_pipe_item_proc
	callback, it allows altering or reader the header being sent.

	server/red_channel: add red_channel_get_first_socket
	Use in main_channel. This is just for backward portability later
	when multiple clients are introduced - needs to be considered (which
	sockets do we want to export from libspiceserver?)

	server/red_channel (+): remove red_channel_add_buf

	server/tunnel: pass SpiceMarshaller reference from send
	Introduce SpiceMarshaller param to all send's that do add_buf

	Next patch will use marshaller in all functions that currently don't by
	replacing red_channel_add_buf with marshaller add_ref. Note - currently
	tunnel is broken due to wrong size in messages.

	server/red_channel (all): add red_channel_get_stream
	use in config_socket, this makes the stream internal to the RedChannel
	implementation that will change later for multiple client support.

	ring: add RING_FOREACH{,_SAFE,_REVERSED}

	server/red_channel (all): handle MIGRATE_DATA and MIGRATE_FLUSH_DATA
	Handling done in red_channel instead of per channel, using call backs
	for the channel specific part.
	Intended to reduce furthur reliance of channels on RedChannel struct.

	The commit makes the code harder to understand because of the artificial
	get_serial stuff, should later be fixed by having a joint migration
	header with the serial (since all channels pass it).

	server/red_channel (all): add red_channel_get_marshaller
	For ussage in the send_item callback. It's only valid during this
	time anyway (should make it return NULL in other occasions?)

	No more direct usage of RedChannel.send_data.marshaller by channels.

	x11: Use _exit rather then exit on X errors (rhbz#680763)
	This avoids us trying to restore the original resolution when we're fullscreen
	and an X error happens. As restoring fullscreen is a bad idea then as this
	involves making more X calls, which can get us stuck (in side an XLockDisplay
	call for example).

2011-02-09  Alon Levy  <alevy@redhat.com>

	update required minimal libcacard to 0.1.2

	client/smartcard: libcacard dropped ReaderAddResponse
	uses VSC_Error with code==VSC_SUCCESS instead. This means that the VSC_Error
	message is overloaded. Instead of the other option of adding a message id,
	since the connection is TCP so no messages may be dropped or reordered, by
	having each message followed by a response there is no ambiguity. Still
	this commit adds a queue for messages that we only have one of which outstanding
	at a time, i.e. send, wait for response, send the next, etc. This further
	simplifies the logic, while not adding much overhead since only when spicec
	starts up it has a situation where it needs to send two events (ReaderAdd
	and ATR for Card Insert).

	server/smartcard: don't push our own error on reader add
	The device already sends one. There are actually two connections going
	on:
	 server to client - this is the smartcard channel, it reuses the VSC protocol.
	 server to device - this is an internal connection using VSC too.

	We generally just passthrough all messages from the client to the device,
	and from the device to the client. We only rewrite the reader_id because
	the device knows about a single id (it is actually a card id), and we
	may manage more then one in the future.

	Bottom line is that there was an extra VSC_Error message reaching the client.

2011-02-07  Alon Levy  <alevy@redhat.com>

	client/smartcard: ignore VSC_Init

	server/smartcard: ignore VSC_Init from client

	server/smartcard: print instead of assert on bad reader_id in smartcard_char_device_on_message_from_device

	server/red_channel: red_channel_event: push on blocked
	try to push either on signal (write available) or when blocked
	and read signaled. From red_worker, copied for compatibility when
	switching later to RedChannel in red_worker. Doesn't make a lot of
	sense (but works), see comment in patch.

	server/red_channel: use red_channel_receive

	from red_worker

	server/red_channel (tunnel): change sig of red_channel_handle_message
	for later usage with red_worker

	server/red_channel: make MAX_SEND_VEC 100
	MAX_SEND_VEC was 100 for DisplayChannel's RedChannel implementation which is being replaced
	with RedChannel in red_channel. So changing from 50 to 100 in red_channel
	(make this configurble?) - effectively increased memory usage by:
	(100-50)*sizeof(iovec)*(num_of_channels-2) ==(arch 64bit) 50*16*6 ~ 5k
	Not terrible.

	server/red_channel: reflect SpiceDataHeader fields in handle_parsed_proc

	server/red_channel: add red_channel_pipe_add_push

	server/red_channel: add hold_item (from red_worker)
	hold_item called on init_send_data, matching release.
	This is not the behavior of red_worker - we ref++ (==hold_item) when
	sending the item, and --refs when releasing it, instead of only holding
	if the send is blocked.

	Note 1: Naming: hold_pipe_item is the proc name, the variable is called
	hold_item, this is similar to release_item/release_pipe_item naming.

	Note 2: All channels have empty implementation, we later use this when
	red_worker get's RedChannelized.

	server/red_channel: add out_bytes_counter (unused)

	client: log subject-host mismatch, and raise ssl warnings to errors

	a print is possible but I didn't test (may be too verbose, also
	preferable to be a debug print if so, and we don't have that option
	in the code atm - probably an environment variable will do, or adding

	common/canvas_base.c: remove unused variables

	spicec: Remove spice-client watermark (rhbz#662450)
	This patch stops us from drawing the spice client watermark at the top of
	the virtual machine view. We have had requests through several channels to
	remove this as it has little added value, and is seen as annoying by some.
	Given that we now also have a bugzilla for this I think it is time we really
	remove it.

	spicec-x11: Let the window manager place our window the 1st time (rhbz#662407)
	The problem is that RedWindow::show calls the XLib MoveWindow function
	on the window after it has been mapped, moving it to the location in
	_show_pos. This is seen by the window manager as the application saying
	I know exactly where I want my window to be placed, don't do placing for
	me. Which causes the client window to always be shown at pos 0x0, even
	though that may not be the best location.

	What this patch does is:
	1) It makes RedWindow::show not call MoveWindow when a window is
	   first created normally and then shown
	2) It makes RedWindow::show still call MoveWindow when:
	   -when the window has been shown before, and was hidden for some
	    reason (controller interface), and is now being re-shown
	    so that it ends up being re-shown at its old position
	   -when the window is a fullscreen window (screen.cpp always
	    calls move on the window before showing it to set its position)
	   -when the user switch from windowed mode -> fullscreen ->
	    windowed mode again, to make sure that the windowed mode window
	    is shown in the same position as before switching to fullscreen
	    mode

	spicec-x11: Add a class hint to our window managet hints
	This helps people who want to tell their windowmanager to do something special
	with spicec, like make it sticky, or whatever, see:

	spicec: do not call connect_secure when connect_unsecure fails due to protocol version mismatch (v2)
	If connect_unsecure failed due to protocol version mismatch, don't try to
	connect_secure with the same version, but retry (connect_secure or
	connect_unsecure) with older version. catch (...) is handled by caller
	at RedChannel::run().

	This solves the following bug: when "new" Spice client (protocol version 2)
	with given secure_port connects to "old" server which is not using the same
	secure_port (or not using a secure_port at all), the client exits immediately.

	In this scenario, the client first tries to use Spice protocol version 2 to
	connect the unsecure port, and altough this fails due to version mismatch, it
	tries to connect to the secure port with the same protocol version 2, which is
	a wrong behavior, fails due to socket error 10061 (WSAECONNREFUSED -
	Connection refused) and handled mistakenly by immediate exit, instead of
	retrying with protocol version 1.

	Fix by reading data anyway, and discarding it after parsing (and reading) whole

	spicec-x11: Fix unhandled exception: no window proc crash (rhbz#655836)
	When XIM + ibus is in use XIM creates an invisible window for its own
	purposes, we sometimes get a _GTK_LOAD_ICONTHEMES ClientMessage event on
	this window. Since this window was not explicitly created by spicec, it
	does not have a Window Context (with the event handling function for the
	window in question) set. This would cause spicec to throw an unhandled
	exception and exit.

	This patch replaces the exception throwing with silently ignoring
	ClientMessage events on Windows without a Context and logging a warning
	for other event types.

2010-11-22  Hans de Goede  <hdegoede@redhat.com>

	spicec-x11: Fix modifier keys getting stuck (rhbz#655048)
	Currently modifier keys (ctrl, alt) can get stuck when using the x11 client.
	To reproduce under gnome:
	-focus the client window without causing it to grab the keyborad (click on
	 the title bar not the window)
	-press crlt + alt + right arrow to switch virtual desktop
	-press crlt + alt + left arrow to switch back
	-notice ctrl + alt are stuck pressed

	What is happening here is:
	-We get a focus out event, caused by the hotkey combi key grab, focus event
	 notify mode == NotifyGrab, and release all keys -> good
	-We get another focus out event, as we really loose the focus.
	 notify mode == NotifyWhileGrabbed, which we ignore as we already lost
	 focus before
	-We get a focus in event, as the focus is returning to us, but we don't
	 really have the focus yet, as the hotkey combi key grab is still active
	 (ie ctrl + alt are still pressed).
	 We now sync the vm's modifier key state with the current X-server state,
	 telling the vm ctrl + alt are pressed. Note we do this by directly reading
	 the X-server keyboard status, we are not getting any key press events from the
	 X-server -> bad
	-We get another focus in event, as we really get the focus back,
	 notify mode == NotifyUngrab. We ignore this one as already have gained the
	 focus before. If we were to sync the vm modifier state here, all would be
	 well we would no longer see the modifier keys pressed, or if we would we
	 would get a release event when they get released (testing has shown both).

	The solution here is to ignore the first focus in event, and do the modifier
	sync on the second focus in event, or more in general to ignore focus events
	where notify mode == NotifyWhileGrabbed.

	spicec-x11: Add a few missing XLockDisplay calls (rhbz#654265)
	The XIM functions end up waiting for a reply from the server, so they
	need locking around them. Idem for the XLookupString call.

2010-11-09  Hans de Goede  <hdegoede@redhat.com>

	spicec: Don't show gui when connection info is specified on the cmdline
	Currently when compiled with the gui enabled if you specify a host to connect
	to on the cmdline the gui flashes by (show_gui gets called, then the connect
	handler calls hide_gui as soon as the connection is made).

	This patch removes this ugly flashing by of the gui.

	spicec: Remove empty show / hide gui functions
	When compiling without gui support just don't call show / hide
	gui, rather then making them stubs, this makes it easier to follow what is
	going on.

	spicec: Fix info layer sometimes not showing
	Currently we are calling show_info_layer from hide_gui in application.cpp, but
	there are 2 cases where this does not happen:

	1) When compiled without gui support hide_gui is a complete nop, so we never
	   show the info layer when compiled without gui support
	2) When run with --controller we never show the gui, and hide_gui
	   checks if there is a gui to hide as the first thing and if not returns
	   resulting in show_info_layer not being called, and thus the info layer
	   not showing when launched from the xpi

	This patch fixes both by adding a call to show_info_layer from
	on_visibility_start note that on_visibility_start also calls hide_gui,
	so in some cases show_info_layer may be called twice, this is not a
	problem as show_info_layer is protected against this.

	Remove no longer used wstring_printf functions

	client: Interpret the title control message as utf8 instead of unicode16
	The activex browser plugin is sending unicode16 text, where as the
	xpi one is sending utf8 text. After discussing this on irc we've decided
	that utf8 is what we want to use. So the client (this patch), and the
	activex will be changed to expect resp. send utf8 text as the title.

	spicec-x11: Change source of controller socket name, fixing CVE-2010-2792
	The socket name used to communicate between the xpi browser plugin and the
	spicec was predictable allowing a non priviliged user on the same system
	to create the socket before spicec does and thus intercept the messages from
	the xpi to the client, including login credentials. This security vulnerability
	has been registred with mitre as CVE-2010-2792:
	http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-2792

	This patch changes the controller code to instead read the socket name
	from an environment variable which gets set by the xpi before executing
	the spicec, making the socketname private between the client and the xpi.

	Note that this means that the controller will only work with an xpi which
	has matching changes, the changes are present in the latest version of the
	xpi as available as update for / with RHEL-5.5 and RHEL-6.0 .

2010-10-18  Hans de Goede  <hdegoede@redhat.com>

	Release 0.6.3

	Make the gui use Application::hide_gui rather then hide_me
	Now that Application::hide_me actually does what the name suggests
	(hide the entire client, ie all client windows), the gui using it to
	not show the gui layer leads to the entire client disappearing when
	one presses close in the GUI or dismisses a GUI dialog. This patch makes
	the GUI code call hide_gui instead of hide_me, fixing this.

	Bump version to 0.6.2

	Update NEWS for 0.6.2 release

	spicec-x11: Fix window management under KDE
	There were 2 issues with window management under KDE
	1) When an app does its own focus management like we do, kwin expects
	   an explicit raise for the app to get to the top, so we did have focus,
	   but would have other windows (partially) covering the client window
	   -> do a raise after setting focus to ourselves
	2) When switching from fullscreen <-> window, we unmap and remap our
	   window, then set focus to ourselves. kwin thinks this means we're trying
	   to steal the focus without the user asking for it. This patch makes us
	   set the _NET_WM_USER_TIME property on our window, this helps kwin's
	   focus stealing code to see that we are really not stealing the focus,
	   just responding to a user event.

	client: change monitor mode setting <-> fullscreen window mode setting order
	1) Make the order when starting up in fullscreen mode the same as when
	   switching from window -> fullscreen:
	   First set the mode, then make the window fullscreen
	2) Change the order when leaving fullscreen mode, first restore the original
	   monitor mode, then make the window non fullscreen. Changing the monitor
	   mode in X11 causes the window manager to re-arrange windows, and if this
	   happens while compiz is busy mapping the window it gets confused and
	   maps the window with a maxmimized size.

	spicec-x11: Change WmSizeHints in fullscreen mode
	Some window managers will ignore the fullscreen hint, unless WmSizeHints
	allow them to resize the window so that they can give it the size of
	the roo-window. This fixes fullscreen mode in compiz.

	spicec-x11: Add missing XLockDisplay around XRRSet* calls
	XRRSet* calls wait for a XReply, so add a missing XLockDisplay,
	this fixes a hang (due to a race so not always) when switching between
	windowed and fullscreen mode.

	client: Do not try to send display_config until we've received the agent caps
	Currenty, we check the agent caps in RedClient::handle_agent_connected
	for VD_AGENT_CAP_DISPLAY_CONFIG and if present send display_config, but at
	this time we have not received the caps yet, so remove this.

	Also the send_agent_display_config call in on_agent_announce_capabilities
	lacks a check for _agent_disp_config_sent, and we send the display config
	before announcing that we may do so by sending our own caps, which seems
	inpolite.

	spicec: add controller
	Spice client controller enables external control (e.g., by XPI or ActiveX) of
	the client functionality.

	The controller protocol enables setting parameters (host, port, sport, pwd,
	secure channels, disabled channels, title, menus, hotkeys etc.), connecting
	the server, showing and hiding the client etc.

	The controller is based on the cross-platform named pipe.

	spicec: add foreign menu
	Spice foreign menu enables external control of the client menu.

	The foreignmenu protocol enables an external application to:
	add a submenu, set its title, clear it, add/modify/remove an item etc.

	server: remove useless agent send_tokens
	We are keeping track of tokens for sending agent data to the client, but
	the client send an initial value of ~0, and never gives us new send tokens
	so this is all rather useless -> remove it.

	Note that it is kept in the migration data struct for compatibility reasons.

2010-10-15  Hans de Goede  <hdegoede@redhat.com>

	Call read_from_vdi_port() from vdi_read_buf_release()
	read_from_vdi_port(), called from vdagent_char_device_wakeup() may
	fail to consume all data because no buffers are available in the
	read_bufs ring. When this happens we would fail to ever read more data
	from the agent on the guest as the port is throttled and stays throttled
	until we've consumed all data from the current buffer.

	This patch re-enables the call to read_from_vdi_port() from
	vdi_read_buf_release(), so that we will try the read again when space
	becomes available in the read_bufs ring.

	Together with another nasty hack in the linux guest virtio_console
	driver, where it waits for a write to be acked by the host before
	continuing with the next one, this can lead to a linux guest
	getting stuck / hang (until the write is read by the spice-server
	which never happens becaus of the above issues).

	Note that even with this patch, the guest will still gets stuck due to
	a bug in watch_update_mask in spice-core in qemu, which causes writing
	to the client to never resume once it blocked. A patch for this has been
	submitted to qemu.

	server: always call read_from_vdi_port() in a while loop
	read_from_vdi_port() MUST always be called in a while loop until it returns 0.

	This is needed because it can cause new data available events and its
	recursion protection causes those to get lost. Calling it until it returns 0
	ensures that all data has been consumed.

	Example scenario where we can fail to read the available data otherwise:
	- server/reds.c: vdagent_char_device_wakeup get called
	  by hw/spice-vmc.c because data has arrived from the guest,
	- hw/spice-vmc.c: vmc_read get calls
	- If the vmc_read call depletes the current buffer it calls
	  virtio_serial_throttle_port(&svc->port, false)
	- This causes vmc_have_data to get called, which if in the
	  mean time another buffer has arrived causes
	  vdagent_char_device_wakeup to gets called again
	  (so recursively)
	- vdagent_char_device_wakeup is protected against recursive
	  calling and ignores the second call (a nasty hack)
	- if no other data arrives, the arrived data will not get read

	Don't crash when a client disconnects while there were pending writes

	spicec-x11: add support for image copy and paste

2010-10-12  Alexander Larsson  <alexl@redhat.com>

	Replace epoll with select in X client
	The use of epoll in the client is totally overkill in terms of
	scalability, and its a problem for portability. The OSX port converts
	this to use select, but keeps some of the old complexities in the code.
	This new patch makes it simpler and look much more like the windows
	code.

2010-10-12  Gerd Hoffmann  <kraxel@redhat.com>

	server: add channel notifications.
	This patch adds a channel event callback to the spice core interface.
	This new callback will be called for three events:

	  (1) A new connection has been established.
	  (2) The channel is ready (i.e. authentication is done,
	      link message verification passed all tests, channel
	      is ready to use).
	  (3) Channel was disconnected.

	Qemu will use this to send notifications to the management app.

2010-10-11  Hans de Goede  <hdegoede@redhat.com>

	spicec-x11: Put locks around xlib calls which wait for a reply
	Since libX11-1.3.4 the multi-threading handling code of libX11 has been
	changed, see:
	http://cgit.freedesktop.org/xorg/lib/libX11/commit/?id=933aee1d5c53b0cc7d608011a29188b594c8d70b

	This causes several issues. One of them is the display inside the
	client not getting updated when there are no XEvents being generated,
	this is caused by the following part of the referenced commit message:

	Caveats:
	- If one thread is waiting for events and another thread tries to read a reply,
	  both will hang until an event arrives. Previously, if this happened it might
	  work sometimes, but otherwise would trigger either an assertion failure or
	  a permanent hang.

	We were depending on the otherwise behavior and apparently were lucky.
	This can be seen by starting F14 in runlevel 3 and then doing startx
	and not touching the mouse / keyb afterwards. Once you move the mouse
	(generate an event you see the UI contents being updated but not before.

	Another thing both I and Alon (iirc) have seen are hangs where 2
	threads are stuck in XSync waiting for a reply simultaneously. This might
	be related to libxcb version, according to the libX11 commit a libxcb
	newer then 1.6 was needed, and my system had 1.5 at the time I saw this
	after updating to libxcb 1.7 I can no longer reproduce.

	This patch tackles both problems (and is needed for the 1st one
	indepently of the 2nd one possibly being fixed) by adding XLockDisplay
	calls around all libX11 calls which wait for a reply or an event.

2010-10-09  Hans de Goede  <hdegoede@redhat.com>

	spicec: Do not try to do accounting of pci memory
	Without this patch spicec reproducely hangs in
	GlzDecoderWindow::pre_decode_update_window().

	When GlzDecoderWindow::will_overflow() returns true,
	GlzDecoderWindow::pre_decode_update_window(),
	waits for a call to GlzDecoderWindow::post_decode()
	to free up some memory

	This happens even though there still is pci memory
	available (otherwise the driver would not have
	been able to send an image to decode in the first
	place).

	The GlzDecoderWindow::post_decode() call never happens
	as the server is waiting for a reply to the decode
	of the hanging image, causing the client to hang
	for ever.

	This patch fixes this by simply removing the
	"attempted" pci memory accounting. As there is no
	need for that, as the driver already must keep
	track of pci memory usage.

	I've verified that both the old and new Xorg drivers
	take care of not overusing the pci memory themselves
	I would expect the same to be true for the windows
	driver.

	Note the calculating of the glz_window_size in
	red_client.cpp cannot be removed as the calculated
	value is send as part of the SpiceMsgcDisplayInit on
	connect.

	So they may not send agent messages directly, instead they should post
	events to the main channel loop.

	spicec-x11: Remove a race window in selection ownership release code
	Well almost remove it, it was possible that another x11 app would acquire
	selection ownership, and we would receive a release message from the
	agent before having processed the xselection ownership change event.

	Then we would set the selection owner to none, overriding the new owner.
	As the comment in the patch indicates there still is a minute window left
	where something similar can happen after this patch. Nothing we can do
	about that (I blame the libX11 selection API).

	spicec: Move setting of clipboard_owner to guest to platform code
	Atleast under x11 there is a race condition when setting the clipboard
	owner to guest from the RedClient code rather then doing it in Platform.

	After the XSetSelectionOwner() in Platform::on_clipboard_grab(), which runs
	from the main message loop thread, the x11 event thread can receive a
	SelectionRequest event from another x11 app, before the RedClient code
	has set the clipboard owner, which will trigger the owner != guest
	check in the SelectionRequest event handling code.

	By moving the setting of the owner in to Platform::on_clipboard_grab() it
	gets protected by the clipboard lock, which closes this tiny race.

	spicec-x11: make get_clipboard_type handle the None Atom

	spicec-x11: protect against recursive incr properties

	spicec-x11: If the clipboard was large return the memory to the system

	spicec-x11: use malloc / free / realloc for clipboard data
	As we need a realloc function it is better to use malloc / free /
	realloc then to diy, esp. as realloc can grow the buffer without
	needing a memcpy.

	spicec-x11: Use a queue for XSelectionRequest events
	XSelectionRequest events must be answered in the order they were
	received. But for TARGETS request we can answer directly, where as
	other requests need to go through the agent. This causes us to handle
	things out of order, and this can cause us to have more then one
	requets outstanding with the agent, which is also not what we want.

	So this patch introduces a queue for XSelectionRequest events, causing
	us to handle them 1 at a time and always in order.

	spicec-x11: handle multiple types per grab
	And also handle many x11 targets (ie utf8 variants) to a single agent
	type mapping.

	spicec-x11: Add XFlush calls were needed
	Since we do not always "pump" libX11's event loop by calling
	XPending (we only call XPending when there is data to read from the
	display fd), we must always explictly flush any outstanding requests.

	This patch adds a whole bunch of missing XFlush calls.

	spicec-x11: Force processing of ownerchange event when releasing the cb
	Make sure we process the XFixesSetSelectionOwnerNotify event caused by
	us setting the clipboard owner to none, directly after setting the owner
	to none. Otherwise we may end up changing the clipboard owner to none, after
	it has already been re-owned because the XFixesSetSelectionOwnerNotify event
	to owner none is event is still pending when we set the new owner, and
	then changes the owner back to none once processed messing up our clipboard
	ownership state tracking.

	I saw this happening when doing copy twice in succession inside the guest.

	spicec-x11: Request targets from new clipboard owner
	Request targets from new clipboard owner, rather then assuming UTF-8
	(not entirely complete yet, the last pieces will be in another patch).

	Atleast as important this code unifies the selection getting code
	for incr and non incr getting of selection data so that it can be
	used for both getting regular selection data and for getting targets
	selection data.

	This also fixes a big bug in the (I believe untested sofar) incr support
	code which was interpreting the contents of PropertyNotify events as
	XSelectionEvents rather then as XpropertyEvents which are completely
	differen structs!

2010-10-03  Hans de Goede  <hdegoede@redhat.com>

	spicec-x11: remove clipboard_changer hack
	Instead of keeping a flag, we can and should simply check wether the
	new owner reported in the event it us or not. Also check for the
	new owner being none and send a clipboard_release when that is the
	case (through set_clipboard_owner(owner_none)).

2010-10-02  Hans de Goede  <hdegoede@redhat.com>

	Keep track of clipboard ownership
	Given that all clipboard handling is async, it is possible to for
	example receive a request for clipboard data from the agent
	while the client no longer owns the clipboard (ie a
	VD_AGENT_CLIPBOARD_RELEASE message is in transit to the agent).

	Thus it is necessary to keep track of our notion of clipboard ownership
	and check received clipboard messages (both from other apps on the client
	machine and from the agent) to see if they match our notion and if not
	drop, or in case were a counter message is expected nack the clipboard
	message.

	Rename platform clipboard handling functions
	Rename the 4 platform clipboard functions which get called
	upon receival of an agent clipboard message to on_clipboard_*

	The old set_clipboard_* names were confusing as they suggest being
	a class property setter (like set_event_listener) rather then
	event handler, and set_clipboard_owner was causing a name conflict
	with the next patch in this series.

	Move checking for on demand clipboard cap closer to sending of agent messages
	This way the events will always get generated and other things
	(such as clipboard ownership administration, see the next patches)
	can be done in repsonse to the events, even though no message will be send.

	This patch also removes the !_agent_caps check from the capability
	checks, this is not needed as VD_AGENT_HAS_CAPABILITY checks _agent_caps_size
	which will be 0 when _agent_caps is NULL.

2010-10-01  Hans de Goede  <hdegoede@redhat.com>

	Respond to clipb request with an unsupported type with data with a none type
	Currently we send a VD_AGENT_CLIPBOARD_RELEASE when we receive a
	VD_AGENT_CLIPBOARD_REQUEST with a type which we do not support. This is not
	correct, as this means given up clipboard ownership while we may be able
	to answer requests with different types. The correct response is to
	nack the request by sending a VD_AGENT_CLIPBOARD (data) message with a type
	of VD_AGENT_CLIPBOARD_NONE.

	Change VD_AGENT_CLIPBOARD_GRAB to an array of types
	A clipboard owner can indicate that it can supply the data the clipboard
	owns in multiple formats, so make the data passed with a
	VD_AGENT_CLIPBOARD_GRAB message an array of types rather then a single
	type.

	Call intern_atoms() earlier
	We call XFixesSelectSelectionInput with the clipboard_atom, so we musr
	initialize the atoms before calling XFixesSelectSelectionInput.

	Set clipboard_event before calling send_selection_notify
	send_selection_notify used the clipboard_event, so set it before calling
	send_selection_notify.

	wrap XGetAtomName
	XGetAtomName() throws X11 errors when called on a None atom, so wrap
	it catching the None case.

	Handle surface images in DrawOpaque

2010-09-21  Alexander Larsson  <alexl@redhat.com>

	server: Handle self_image in localize_bitmap
	When drawing a drawable with a NULL src bitmap that means we should
	be using the previously generated self_bitmap. Not doing this causes
	a segfault due to accessing the NULL.

	server: Handle NULL image in red_update_streamable
	A NULL src bitmap means self_bitmap, which is not a stream, so abort.

	server: Use the right image size for self_bitmap
	The self_bitmap is the size of self_bitmap_area, not the bbox.
	This is especially important since we later copy the self_bitmap_area
	into the new bitmap, and if that is larger than bbox then we will
	overwrite random memory.

	server: Don't leak QUIC image chunks
	red_put_image() needs to free the chunks for QUIC images, as we
	allocate these when creating the image.

	Fix crash when resetting pixman image transform
	Resetting the transform is done by setting it to the identity
	transform, not passing in NULL. Passing in NULL causes a crash.

	server: Ensure we flush the release pipe after an oom
	We really need to flush the ring to ensure that we push something on the
	release ring. If we don't do this and the ring is not pushed for other
	reasons we will timeout in the guest driver waiting for the ring.

	Release more drawables on OOM
	We've changed how resources are released so they are now being
	freed continuosly, rather than on OOM, since we want to free as early
	possible to avoid fragmentation. So, OOM situations should be a bit
	less common now and signify a real memory shortage, so we should try
	to free up more resources.

	spicec-x11: Fix going into a never ending loop upon xrandr event (#628573) (v2)
	When handling an xrandr event the event_listener->on_monitors_change()
	callback destroys and re-creates the monitor object(s) which results
	in the DynamicScreen or MultyMonconstructor being called, which triggers
	more xrandr events. This causes a never ending event handling loop making
	spicec hang, and eventually making the X-server crash as a backlog
	of events builds up and it oom's.

	This patches this by explictly processing the xrandr event caused
	by the constructor inside the constructor surrounded by the already
	present guard code against recursive xrandr events.

2010-09-02  Alexander Larsson  <alexl@redhat.com>

	Add API to turn on backwards compatibility mode
	When upgrading a cluster of machines you typically do this by
	upgrading a set of machines at a time, making the new machines run
	the new software version, but in a fashion compatible with the old
	versions (in terms of e.g. migration). Then when all machines are
	upgrades, any new features in the new version can be enabled.

	This API allows qemu to limit the set of features that spice uses to
	those compatible with an older version, in order to do an upgrade like
	this. Right now it doesn't really do much, since we don't keep compat
	with 0.4.0 atm (although that may be added later).

	There is no guarantee that any future version of spice support
	being compatible with any previous version. However, we will always
	support compatibility with the previous major version so that clusters
	can be upgraded step by step.

	Fix scaling with large magnification
	When scaling part of an image we need to specify the source
	coordinates in transformed coordinates. For large magnifications this
	means we will get pretty large values.

	Now, if e.g. src_x * transform is larger than 32765, then the
	coordinate ends up outside the pixman 16bit image size, so the
	rendering will not work.

	The fix is to make the src_x/y offset part of the transformation.
	This means its automatically transformed by the correct scaling, and
	the coordinates passed into pixman are not (typically) over 16bit.

	Revert "Fix scaling with large magnification"
	This reverts commit e13be77f33609cb3fdae354ce1f2686ae865f9e0.

	server: fix red_current_flush to flush only the surface that was given as parameter
	A side effect of the previous red_current_flush, which flushed all the surfaces, and was called on a new display channel connection, was
	that red_handle_drawable_surfaces_client_synced sent the most updated surfaces images when needed. However, now, it should
	explicitly call red_current_flush.
	Moreover, since red_current_flush was called on a new display channel connection only if there was a primary surface,
	if the connection of the display channel occurred at the moment of no primary surface, red_handle_drawable_surfaces_client_synced was buggy.

	canvas: Better coordinate rounding in scaling
	When scaling in pixman you give the source coordinates in transformed
	space rather than in the source coordinates. This is a bit problematic
	when both source and destination coordinates are at integer positions, but
	the scaling factor is not an exact 16.16 fixed point value. We used
	to calculate the transformed source based on the floating point
	transformation, which gave the wrong answer sometimes. Now we do the
	calculations based on the fixed point transform that we give pixman.

	However, even with this patch I can still sometimes see issues related
	to this, although they are less bad.

2010-07-09  Alexander Larsson  <alexl@redhat.com>

	Don't marshall bitmap data as pointer, instead send inline

	Add --enable-werror and make it the default only for git builds
	Its not generally a good idea to have released tarballs build with
	-Werror, as later compilers may add warnings breaking old releases, etc.

	Use the right enum types for bitmap_data.type comparisons

	Add files i forgot to commit

2010-07-08  Alexander Larsson  <alexl@redhat.com>

	Update NEWS for release

	remoth -> remote
	modifires -> modifiers
	secore -> secure

	Fix sign warnings from win32 compiler

	Fix inclusion of common files, no need for common/ part

	server: Remove unnecessary pci id/rev checks
	There is no need to check the pci ids or revisions. Thats a contract
	between qemu and the driver, and spice need not care, as long as
	we get the right data from qemu.

	Simplify spice_pixman_region32_init_rects with new types
	Don't manually of SpiceRects to pixman_box32_t now that they are compatible
	and SpiceRect is internal.

	Make all internal structures not be packed

	Remove unused method declarations

	Move SpiceChunks to mem.h

	Move in spice/draw.h from spice-protocol to common/

	Handle the new QXLCursorHeader type

	Use QXLPHYSICAL, not SPICE_ADDRESS in qxl parser

	Properly parse QXLLineAttrs.style

2010-07-08  Gerd Hoffmann  <kraxel@redhat.com>

	remove QXLInterface->has_command()
	Not used any more, zap it before rolling up a release tarball.

	server: add missing ifdef USE_OGL (red_worker.c)

2010-07-07  Gerd Hoffmann  <kraxel@redhat.com>

	Properly parse QXLImage to the new-world SpiceImage
	SpiceImage now replaces RedImage and has all image types in it.
	All image data are now chunked (and as such not copied when demarshalling).

2010-07-07  Alexander Larsson  <alexl@redhat.com>

	codegen: support @chunk on non-pointer arrays
	This is similar to @as_ptr, but generates a single chunk of data.

	Add support for @chunk

	marshaller: Make get_nw_offset() handle deep member references

	Add spice_marshaller_add_ref_chunks

	Add spice_chunks_* helpers

2010-07-05  Alexander Larsson  <alexl@redhat.com>

	Convert SpicePath.segments to a pointer array

	Handle extra size for switch and array the right way
	Even for is_extra_size() we should calculate the mem_size for
	arrays, its just that the parent type (in this case switch) should
	request mem_size if the type is_extra_size.

	marshaller: Add some docs describing the types of sizes

	marshaller: Make @nonnull a propagated attribute
	This cleans up some stuff

	marshaller: Make @c_ptr a propagated attribute
	This simplifies some code

	marshaller: Add generic way to handle propagating attributes
	Also switches @ptr_array to use this

2010-07-01  Alexander Larsson  <alexl@redhat.com>

	Fix build on win32

	Fix 32bit failure in demarshaller
	Due to a typo we always read offsets as pointers, never as SPICE_ADDRESS.

	Update for the SpicePath.segments type change

2010-07-01  Alon Levy  <alevy@redhat.com>

	Make CEGUI optional
	This makes the CEGUI dependency optional and off by default. Restoring
	previous behaviour of exiting on disconnect if disabled.

	- fix for noopengl patch for server
	I still don't have commit access (can't ssh to anarchy) so if someone could commit this (alex) thanks,

	Alon

	Fix for no opengl patch - required to compile the server (fixes missing symbol gl_canvas_init).

2010-07-01  Yonit Halperin  <yhalperi@redhat.com>

	fix for not clearing the cursor ring when the primary surface is destroyed
	fixes a crash in qxl_soft_reset

2010-06-30  Alexander Larsson  <alexl@redhat.com>

	Simplify SpiceLineAttr by removing unsed stuff
	Also in new protocol don't send style data if not needed.

	Automatically marshall SpiceClipRects

	Automatically marshall SpicePath

	Support @marshall to automatically marshall pointers

	Store SpicePath segment count rather than size
	Internally and in the network protocol (for the new version) we
	now store the actual number of segments rather than the size of the
	full segments array in bytes. This change consists of multiple changes
	to handle this:

	* Make the qxl parser calculate num_segments
	* Make the canvas stroke code handle the new SpicePath layout.
	* Fix up is_equal_path in red_worker.c for the new layout
	* replace multiple calls to spice_marshall_PathSegment with a single
	  spice_marshall_Path call
	* Make the byte_size() array size handling do the conversion from
	  network size to number of elements when marshalling/demarshalling.
	* Update the current spice protocol to send the segment count rather than
	  the size
	* Update the old spice protocol to use the new byte_size functionallity
	  to calculate the size sent and the number of elements recieved

	Add spice_marshaller_set_uint32
	With this function you can update an added uint32 after it being added.
	To make this possible all the spice_marshaller_add_add_foo functions
	now return a pointer that can be used as a reference when later
	setting a value.

	Update client and protocol to support the new SpiceClipRects

	demarshaller: Support @c_ptr attributes for pointers
	A @c_ptr pointer is stored in memory as a real pointer rather than a
	SPICE_ADDRESS. This is a temporary thing that will be removed again
	when all SPICE_ADDRESSes have been converted to real pointer.

	demarshaller: Don't parse @zero members
	These just write zeros at the right place in the network protocol
	typically for old back-compat things. We don't want to read these
	back in.

2010-06-30  Gerd Hoffmann  <kraxel@redhat.com>

	qxl-abi: handle clip rect and path references.
	red_parse_qxl.c starts to follow QXLPHYSICAL references and build up
	data structures.  Can zap a bunch of get_virt calls in red_worker.c,
	followed by cleanups.

	(de-) marshaller needs updates to deal with that.  Also I suspect with
	the get_virt() calls being gone we can offload more work to generated
	marshaller code.

	client doesn't build.

	add qxl chunk parser

2010-06-29  Alexander Larsson  <alexl@redhat.com>

	server: Don't call opengl if not enabled
	If USE_OGL is not defined, really don't call or link in the opengl
	backend.

2010-06-29  Yonit Halperin  <yhalperi@redhat.com>

	client: add --include "common.h" for generated marshallers

	fixed unhandled destroy screen in Application:restore_screens_size

	detaching the screen when the primary surface is destoryed and closing the window if the primary surface is not recreated (the monitor has been detached).

	remove unnecessary send of SPICE_MSG_DISPLAY_RESET
	when SPICE_MSG_DISPLAY_RESET was sent, SPICE_MSG_DISPLAY_SURFACE_DESTROY had already
	been sent for all surfaces.
	It also caused a client crash since DisplayChannel::handle_reset assumes that screen
	exists.

2010-06-24  Alexander Larsson  <alexl@redhat.com>

	spice.proto: surface_create.format is of type surface_fmt

	Use smaller size for enums and flags on the network
	This makes the protocol more compact. This was mainly done for the commonly
	used types. Some seldom used ones are still 32bit for future compatibility.

	Remove support for clip by path
	This is not supported currently anyway and was not generated before.

2010-06-23  Alexander Larsson  <alexl@redhat.com>

	spice.proto: No need for @ptr32 as that is now the default

	spice.proto: Don't use @fixedsize for Brush
	There is no reason to send the maximum size on the network, that is just
	a waste of space most of the time.

	Don't send zero data item for clips with no data

	Make pointers 32bit in new protocol format

	marshaller: Correctly determine if switches are fixed size
	Switches are fixed size only if all cases have the same size *and*
	it has a default case or all the valid cases are listed.

	Fix handling of @ptr32 network size

	Remove minor markup in unstable protocol as we're resetting minor to 0

2010-06-23  Gerd Hoffmann  <kraxel@redhat.com>

	fix use-after-free in spice_marshaller_reset

	drop bogous get_virt_delta calls

2010-06-23  Alexander Larsson  <alexl@redhat.com>

	Fix version mismatch error on connect
	Protocol is 0 (auto), 1 (old), or 2 (new). This is (apart from 0) the
	same as the major number for the stable protocol. However, the current major
	is ~(-1) to signify it being unstable, so don't use the major number as source
	for setting or comparing protocol.

	Fix screen resolution changes on old servers
	* Correctly check for existing canvas 0
	* Don't try to unlock the screen size if there is no active screen

2010-06-22  Alexander Larsson  <alexl@redhat.com>

	client: Support connecting to a major==1 server

	Implement display_mode message needed for backwards compat

	Generate marshaller/demarshallers for old protocol

	Add spice1.proto describing the 0.4 version of the network protocolx

	Add support for @virtual markup in spice protocol
	This means the member is not sent on the network at all.
	Instead its initialized to the attribute argument when demarshalled.

	This is useful for backwards compatibility support.

	Make internal generated marshaller functions static

	Support extra prefix in code generators
	This is require when we add a new spice.proto for the old (major 1)
	protocol description.

	Add more emacs mode headers

	Convert client to use indirect calls for message marshalling
	This is required to support multiple versions

	Support creating marshallers that are called indirectly
	This is needed if we want to switch marshallers depending on what
	major version the remote side has.

	Add destructor for demarshalled messages
	This is required because we don't want to free messages that just
	refer to the unparsed message (like SpiceMsgData).

	Also, in the future we might need it for more complex demarshalling.

2010-06-21  Yonit Halperin  <yhalperi@redhat.com>

	fix for not reseting client palette caches on migration

	Lossy compression of RGBA images (on WAN connection)
	The RGB channels are compressed using JPEG.
	The alpha channel is compressed using LZ.

	applying zlib compression over glz on WAN connection

2010-06-21  Alexander Larsson  <alexl@redhat.com>

	Make opengl optional, disabled by default
	The OpenGL renderer isn't really useful right now, its not quite up
	to date, its not really faster than software and it only supports a limited
	subset of drivers. So, lets disable it for now.

	Long term opengl rendering of the 2d part of spice is important if we want
	to combine 2d and 3d rendering (say if spice adds opengl support in the
	protocol). But until then this is isn't useful for normal use.

2010-06-18  Alexander Larsson  <alexl@redhat.com>

	Make generated marshallers build on win32

	Add server/demarshaller.h

	Make sound data @as_ptr to avoid copying data

	Make ping data @as_ptr to avoid copying data

	Make cursor data @as_ptr to avoid copying data

	Support @as_ptr in demarshaller to avoid copying data unnecessary

	Make pointer types in messages be 64bit in memory
	Right now we always assume pointers are stored as SPICE_ADDRESS,
	i.e. 64bit, independent on the size sent on the network.
	This is required for 64bit architectures of course, but slightly overkill
	on 32bit architectures, so needs fixing when all SPICE_ADDRESS elements
	can be made internal.

	Don't pack the message structures

	Make all message structs internal to spice
	We move all message structs from spice-protocol to spice as
	we want to be able to change these as needed internally. The
	on-network format is no longer defined by these structures anyway,
	but rather by the spice protocol description.

	Allow multiple --include args

	Use generated demarshallers in server

	Generate demarshallers on server side

	Make tunnel_service_add members be of cstring array size

	Switch client to use generated marshallers

	Generate and link marshallers into client

	Re-enable cache freeing
	I don't know why this was disabled but it seems like a bad idea

	Convert reds.c to use SpiceMarshaller

	Convert snd_worker.c to use SpiceMarshaller and generated marshallers

	Convert red_worker.c to use SpiceMarshaller for marshalling

	Generate marshallers in server

	Use @ptr32 for 32bit offsets in spice.proto

	Add @nomarshal in a few places where we're marshalling manually

	spice.proto: add @outvar markup
	With this we can reference pointer member with no naming conflicts

	Add support for generating message and structure marshallers

	Add SpiceMarshaller for easy marshalling

	Generate demarshalling code on win32 too

	Client: Use the autogenerated demarshallers
	When a message has been read from the network we now pass it into
	the generated demarshaller for the channel. The demarshaller converts
	the network data to in-memory structures that is passed on to the
	spice internals.

	Additionally it also:
	* Converts endianness
	* Validates sizes of message and any pointers in it
	* Localizes offsets (converts them to pointers)
	* Checks for zero offsets in messages where they are not supported

	Some of this was previously done using custom code in the client, this
	is now removed.

	Generate demarshallers in client

	Add python code to automake system

	Initial import of spice protocol description and demarshall generator
	The "spice.proto" file describes in detail the networking prototcol
	that spice uses and spice_codegen.py can parse this and generate
	demarshallers for such network messages.

	Use the correctly spelled enum values from the new generated enums

	Use the new enums for keyboard modifier flags

	server: optimize red_pipe_replace_rendered_drawables_with_images (lossy bitmaps support related)

	init/destroy lossy surface region

	enabling jpeg on low bandwidth connection

	not using jpeg when sending a surface to the client (the whole surface)
	When a surface is sent to the client using red_send_surface_image, operations were already
	performed on it. Thus it may combine, especially if it is a primary surface, both "picture-like" areas
	and areas that are more "artificial". In order to avoid noticeable artifacts, such surface will be sent lossless.

	send qxl commands to client: support for resending lossy components when jpeg compression is enabled

	infrastructure routines for resending to the client part of surfaces that have been sent lossy.
	The code also handles cases in which the server doesn't hold anymore these surfaces parts, i.e., when
	it holds a more updated version of them. This scenario is handled by replacing commands that were rendered, with images.

	introducing lossy and lz compression in red_send_image

	lossy surface regions in the client: infrastructure for tracking and updating

	support for lossy images in the pixmap cache and fill bits
	1) add an option to determine if a bitmap can be sent lossy to the client
	2) when required, replacing lossy cache items with their correspending
	   lossless bitmaps

	Revert "[debug] migration troubleshooting"
	This reverts commit 08927fabe57c17086fe3bce3a9ca166e2309349e.

	complete NetWireInterface redesign, make red_tunnel_worker.c build.

	add spice-experimental.h
	Supposed to be used for work-in-progress bits,
	where interfaces are not finalized yet.

	Moved over vdi port interface, tunnel interface
	and spice client migration functions.

	zap vd_interface.h
	move over content to spice.h

	vd_interface.h cleanups.
	Drop leftover bits which are not used any more.
	Rename DrawArea to QXLDrawArea.

	NetWireInterface: redesign

	zap MigrationInterface
	Remove remaining MigrationInterface bits.

	migration: new api
	Add new API for migration, based on what RHEL-6 has.

	[debug] migration troubleshooting

	zap migration code
	Drop all code which depends on accessing the migration file handle.

	replace worker load/save with loadvm_commands, allow keeping surface content
	Add worker->loadvm_commands.  qemu will uses this to send a series of
	commands needed to restore state after savevm/loadvm and migration.
	That will be one create-surface command per surface and one cursor-set
	command for the local pointer.

	The worker->save/load functions are not needed any more.
	Likewise the interface->{get,set}_save_data callbacks.

	Surfaces created via loadvm_commands *will* not be cleared.  Also
	primary surfaces are not cleared any more (unconditionally, although
	we could do that conditionally on loadvm using the flags field in
	QXLSurfaceCreate).

	surface: keep metadata (aka create command) in device memory.
	With this patch applied the spice server will not release surface create
	commands for the whole lifecycle of the surface.  When the surface is
	destroyed both create and destroy commands are released.

	This has the effect that the surface metadata (size, depth, ...) is kept
	in qxl device memory.  This in turn makes it alot easier for qemu to
	handle savevm/loadvm.  It just needs to do some minimal command parsing
	and maintain pointers to the create commands for the active surfaces.

	kill spice_server_set_mouse_absolute
	Not needed.  Just register/unregister the tablet interface instead.

	vdi port: redesign.
	Pretty straight forward.

	One thing we should think about is if and how we are going to deal
	with multiple ports here?

	With vdi port using virtio-serial as communication channel to the guest
	it is easy to have multiple ports, i.e. we might want to use a second
	instance for clipboard data.  That implies that we need support for
	multiple channels all the way through the stack ...

	constify SpiceBaseInterface

	SoundInterfaces: redesign

	TabletInterface: redesign

	QXL: redesign.

	MouseInterface: redesign

	KeyboardInterface: redesign.
	This is the direction I wanna take with all interfaces:  Clearly
	separate interface (aka version information and function pointers)
	and state information.  SpiceKbdInterface defines the interface,
	SpiceKbdInstance maintains per-instance state information.  Keyboard
	hasn't much beside a pointer to SpiceKbdInterface, for other
	interfaces this very likely will be different.

	s/CoreInterface/SpiceCoreInterface/

	VDInterface: redesign.
	VDInterface has been renamed to SpiceBaseInterface. Dropped base_version
	element, shlib versioning should be used instead.  Dropped id element,
	it is passed to spice_server_add_interface() instead.  Now
	SpiceBaseInterface has static information only, multiple interface
	instances can share it.

	Added SpiceBaseInstance struct for maintaining per-instance state
	information.  Adapted spice_server_{add,remove}_interface() functions
	to the new world.

	shlib major

	minor timer interface cleanups.
	Make the timer interface largely look like the watch interface.
	Simliar naming convention for the functions (timer_*) and a
	opaque SpiceTimer type.

	new watch api: kill old api

	new watch api: switch channels

	new watch api: switch sound

	new watch api: switch migration

	new watch api: switch inputs

	new watch api: switch ssl accept

	new watch api: switch main channel

	new watch api: switch liasync read

	new watch api: switch listening sockets

	introduce new watch api
	This patch adds a new file handle watch interface to libspice, featuring
	three callbacks:

	  (1) watch_add() -- create a new file watch.
	  (2) watch_update_mask() -- change event mask.  spice frequently
	                             enables/disables write notification.
	  (3) watch_remove() -- remove a file watch.

	libspice users must implement these functions to allow libspice
	monitoring file handles.

	The old interface (set_file_handlers) doesn't explicitly express the
	lifecycle of a watch.  Also it maps 1:1 to a qemu-internal function.
	In case the way qemu implements file watches changes (someone sayed
	QemuIONotifier?) this will break horribly.  Beside that it is very
	bad style.

	Follwing patches will switch over users one by one to the new interface
	and finally zap the old one.

	fix visibility

	zap CoreInterface->{term_printf,log}
	Was used to print stuff to the qemu monitor.
	Fundamentally incompatible with QMP.  Remove.

	zap qterm interfaces
	old way to handle monitor, obsolete.

	zap CoreInterface->(un)register_change_notifiers()
	spice_server_add_interface() and spice_server_remove_interface()
	can be used instead.

	zap CoreInterface->next()
	Interfaces must be registered after spice_server_init().
	The "next" callback is used to discover interfaces
	registered before spice_server_init().  Which is a empty
	list and thus pretty pointless.  Remove it.

	channel security cleanup
	- drop spice_channel_name_t enum, use spice-protocol defines instead.
	- switch spice_server_set_channel_security() channel parameter from
	  enum to string.
	- drop spice_server_set_default_channel_security(), use
	  spice_server_set_channel_security with channel == NULL instead.

	zap spice_parse_args + spice_usage_str
	First step to throw out the old interface.

	Clear alpha in xRGB destination to avoid pixman setting it to 0xff
	Pixman sometimes sets the ignored high byte to 0xff during alpha
	blending. This is correct according to pixman specs, as the high
	byte is ignored. However its not what windows expects, and it causes
	unnecessary regions with non-zero high byte, causing us to
	send rgba data instead of rgb which compresses worse.

	So, we detect this and clear the high byte.

	Fix line lengths and tabs

2010-04-26  Gerd Hoffmann  <kraxel@redhat.com>

	fix two warnings

2010-04-23  Alexander Larsson  <alexl@redhat.com>

	Remove surface format workaround now that win32 driver is fixed
	The win32 driver makes all 32bit surfaces be xRGB now, so we
	can remove this old workaround.

	Fix up win32 client with recent changes

	Win32 canvas fixes

	If we have alpha in a 32bit rgb surface, ensure we send that
	If we don't then alpha is lost which is problematic if the surface
	is later used as with alpha_blend and SRC_SURFACE_HAS_ALPHA.

	Support alpha surface sources and destinations

	Localize palettes for LZ PLT format
	This is needed since they always decode to 32bit mode.

	Server: Use the right image format when updating from a surface

	Make each surface its own depth/format
	Surface creation now specifies the exact format, not only the bit depth
	of each surface which is used for rendering.

	Additionally we now actually store the surfaces in that format, instead
	of converting everything to 32bpp when drawing or e.g. handling palettes.

	Client: Support pixmap format conversion in copy_pixels
	In order to be able to support 16bit canvases on 32bit screens and 32bit
	canvases on 16bit screens we need to handle format conversion when drawing
	RedPixmaps.

	The way this works now for X11 is that we only have one PIXELS_SOURCE_TYPE
	for pixmaps, which always has a pixman_image_t for the data, but additionally
	it has an XImage (shared mem or not) if the screen the pixmap was created
	for (i.e. an explicit one or the default screen) has the same format as
	the pixmap.

	When we draw a pixmap on a drawable we have two variants. If the pixmap
	has a XImage and it matches the format of the target drawable then we
	just X(Shm)PutImage it to the drawable. If the formats differ, then we
	create a temporary XImage and convert into that before drawing it to
	the screen.

	Right now this is a bit inefficient, because we always allocate a new
	temporary image when converting. We want to add some caching here, but
	at least this lets things work again.

	X11 client: Add helper for XImage construction

	Add utility functions to create XShm images

	Create screen composit area in same format as window
	This way we don't have to convert when drawing to it, or drawing it to
	the dc.

	Add helper to compare RedDrawable::Formats for copy compabible
	Being copy compatible means the format are identical except
	that some bits in the source may be ignored in the destination.

	Add RedDrawable::Format get_format()
	This is useful because we can e.g. create pixmaps in the same format as
	a window.

	Add XPlatform::get_screen_format for X11

	Move RedPixmap::Format to RedDrawable::Format
	We need to know the format for other drawables too (like for instance
	the native format of a window), so we're pushing this down.

	This changes a bunch of references to be RedDrawable::, but not all.
	The the old RedPixmap:: references still work, but will be phased out.

	Make client canvas and pixmaps handle more formats and simplify
	We now support 16bit format pixmaps as well as the old ones. Including
	both 555 and 565 modes.

	We drop the palette argument for pixmap construction as it was only
	used for black/white anyway.

	Canvas creation is simplified so that there is no separate set_mode
	state. Canvases are already created in the right mode and never change.

	common: Add lookaside storage for pixman image format
	Ideally we should just read this from the pixman image, but
	there is no API to do so in stable pixman, so we store it.

	Add pixman utilities for bitmap to pixman_image_t conversion

	Add support for 16bit rop3

	Add emacs modelines to more files

	Remove unused method canvas_surf_to_invers

	Make client start if screen is 16bpp
	The current glx code is looking for a rgb32 visual and always failing
	if there is none. This means not even software rendering starts up
	on e.g. 16bit visuals. This commit makes it pick software fallbacks
	on 16bit visuals.

	Long term we need to fix the gl implementation to do 16bpp too.

	Client: Don't die if XIM not availible

	Detect XShm extension sanely
	The previous way XShm detection worked failed at least for me, and is
	not the standard way. We now just use XShmQueryExtension and
	XShmQueryVersion.

	Detect big endian systems

	Fix warnings breaking win32 build

	(There is just the primary surface to protect in reiality)

2010-04-08  Alexander Larsson  <alexl@redhat.com>

	Remove leftover AutoVStreamInit class

	Initialize _kill_mark so we don't get spurious valgrind warnings

	Free the jpeg decoder with the stream

	Use libjpeg to decode mjpegs, not ffmpeg
	This is pretty straightforward, although there are two weird issues.
	The current encoder has two bugs in the yuv conversion. First of all
	it switches red and blue, due to something of an endianness issue. We
	keep this behavior by switching red and blue. Maybe we want to
	change this in the new protocol version since switching this may
	cause jpeg compression to be worse.

	Secondly, the old coder/decoder did rgb to/from yuv420 wrongly for
	jpeg, not using the "full scale" version of Y that is used in jpeg,
	but the other one where y goes from 16 to 235. (See jpeg/jfif
	reference on http://en.wikipedia.org/wiki/YCbCr for details.)
	The new decoder uses the full range in order to get better quality,
	which means old encoders will show slightly darker images.

	This completely removes all ffmpeg usage in the client

	Update project file to visual studio 2008

	In 'filter' video streaming mode, use a more permissive threshold for distinguishing

	Default opt flags to -O2
	gcc -O3 has some code generation failures due to a combination of
	unaligned (packed) structs and vectorization that can cause
	a crash in canvas_localize_palette().

	And its just safer to use -O2, which is the standard "trusted"
	optimization flags.

	Use nearest scaling for DRAW_ALPHA_BLEND since this is what win32 needs
	DrvAlphaBlend is the only current user of DRAW_ALPHA_BLEND, and its
	defined to do nearest (COLORONCOLOR) scaling, not bilinear.

	Fix up empty region checks in canvas operations
	We rely on not passing on empty rects to the drawing operations by
	checking for empty regions and exiting early. However the checks
	were wrongly using pixman_region32_n_rects(region) == 0, whereas
	we should be using pixman_region32_not_empty().

	Allocations of dynamically sized arrays can use g_malloc_n or g_new etc

	Add new functions to configure spice port and ticketing.  Yes, this is
	incomplete, it includes just the most important bits to get something
	up'n'running.

	These functions are supposed to replace both spice_parse_args() and
	the monitor interaction via qterm interface.

	new libspice api: alloc, initi and free spice server instances.
	The implementation can't handle multiple spice server instances at the
	same time right now.  The API allows this though, so if we fixup the
	implementation some day we don't have to change the API.

	Fix possible quic_usr_more_lines_unstable() crash
	quic_usr_more_lines_unstable() assumes it can allways copy a complete
	scanline.  Well, it can't.  In case the screen rectangle which needs

2010-03-08  Alexander Larsson  <alexl@redhat.com>

	Move draw_rop3 to canvas_base

	Move canvas_draw_stroke to canvas_base

	Move most of the shared draw_xyz() methods from CairoCanvas to CanvasBase
	This adds a set of virtual methods for low-level operations. A subclass
	can choose to implement those and let the default CanvasBase implementations
	handle the highlevel stuff.

	Move canvas_region and group_start/end to canvas_base

	Move virtualization of canvas drawing into common/canvas_base
	Instead of having two virtualizations of the canvas we push the
	virtualization into the canvas code itself. This not only avoids
	the duplication of this code, it also makes the exposed API for the
	canvas much smaller (in terms of exported API).

	It also lets us use the virtualization to implement basic support
	for operations in canvas_base which is then overridden by each canvas
	implementation.

	Make virt mapping an interface

	Make glz_decoder non-optional canvas_base in canvas constructors
	It can still be NULL, but we simplify the headers by always including it.
	There is no practical performance difference here.

	Make canvas Glz decoder integration nicer
	We use a dynamic interface similar to e.g. SpiceImageCache instead
	of passing both function and opaque

	Fix colorkeying in pixman_utils.c
	We were masking out the alpha bit in the key color not int
	the source pixel, so colorkeying didn't work when the high byte
	was != 0. For instance in the shutdown dialog in XP.

	Covert cairo canvas put_image() to pixman

	Replace custom region implementation with pixman_region32_t
	pixman_region32_t is an efficient well tested region implementation (its

	Convert cairo canvas draw_opaque() to using pixman

	Convert cairo canvas draw_fill() to using pixman

	Add possibility to not invert bitmask in canvas_get_mask()
	This allows the pixman implementation to instead invert the (generally
	smaller) region instead of duplicating the bitmap to invert it.

	Use pixman_image_t instead of cairo_surface_t as the generic pixman container
	This allows us to use the simpler dependency of pixman outside of the
	cairo backend, and it later lets us move the cairo backend to using
	pixman only.

	Turn image and palette cache into c style dynamic interface
	Instead of passing a bunch of function pointer and an opaque
	pointer we make a real type and add a vtable pointer to it.
	This means we can simplify all the canvas constructors, etc.

	Add optional templated base class to Cache and SharedCache
	We want this for integration with C-style classes.

	Add pixman_image_t referencing the cairo_canvas bits
	This references the same data as the cairo surface and can be used
	for drawing to the surface using direct pixman calls instead.

	Add line rasterizer

	spice client: sticky Alt activation when holding an Alt key: bug #505912.
	Additional changes that were required for the feature:
	    1) focusing on the pointed window in full screen mode
	    2) In X11 - handling events that occur during keyboard ungrabbing
	    3) In X11 - handling Leave/Enter Notify events that occur during keyboard grabbing/ungrabbing
	    4) In X11 - fix for focus events that are handled in the wrong order (happens when
	       focus events occur during grabbing the keyboard)
	    5) In X11 - ignoring key release events during key holding
	    6) In Windows - synchronizing keyboard release events that occured during a modal loop

	spice client: cosmetic changes

	spice client: Transfer all channels run loop from EventsLoop class to ProcessLoop class

	spice client: creating a general process loop.
	The process loop is responsible for: 1) waiting for events 2) timers 3) events queue for
	actions that should be performed in the context of the thread and are pushed from other threads.
	The benefits:
	1) remove duplicity: till now, there was one implementaion of events loop for the channels and
	another one for the main thread.
	2) timers can be executed on each thread and not only on the main thread.
	3) events can be pushed to each thread and not only to the main thread.
	In this commit, only the main thread was modified to use the new process loop.
