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.

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
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)
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/
