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)". |

SPICE: Simple Protocol for Independent Computing Environments
=============================================================
SPICE is a remote display system built for virtual environments which
allows you to view a computing 'desktop' environment not only on the
machine where it is running, but from anywhere on the Internet and
from a wide variety of machine architectures.
Installation
------------
The SPICE package uses GNU autotools, so the build install process
follows the standard process documented in the INSTALL file. As a
quick start you can do
./configure --prefix=/usr --sysconfdir=/etc \
--localstatedir=/var --libdir=/usr/lib
make
sudo make install
Or to install into a private user specific location
./configure --prefix=$HOME/spice
make
make install
The following mandatory dependancies are required in order to
build SPICE
Spice protocol >= 0.9.0
Celt >= 0.5.1.1, < 0.6.0
Pixman >= 0.17.7
OpenSSL
libjpeg
zlib
Cyrus-SASL
The following optional dependancies increase the available
functionality
GE Gui >= 0.6.0, < 0.7.0 (GUI app support)
OpenGL (GUI app support)
Alsa (Linux support)
XRandR >= 1.2 (X11 support)
Xinerama >= 1.0 (X11 support)
libcacard >= 0.1.2 (Smartcard support)
Slirp (Tunnelling support)
Communication
-------------
To communicate with the development team, or to post patches
there is a technical mailing list:
http://lists.freedesktop.org/mailman/listinfo/spice-devel
There is also a mailing list for new release announcements:
http://lists.freedesktop.org/archives/spice-announce/
To view known bugs, or report new bugs, in SPICE visit
https://bugs.freedesktop.org/describecomponents.cgi?product=Spice
Bugs found when using an OS distribution's binary packages should
be reported to the OS vendors' own bug tracker first.
The latest SPICE code can be found in GIT at:
http://cgit.freedesktop.org/spice/
