call cleanup(). if that process still appears to exist then the
init() fails. otherwise some cleanup is performed and the init()
proceeds. a synergy server started while another is running will
now exit immediately without interfering the original server.
MsgWaitForMultipleObjects(): it will not return immediately
if an event already in the queue when it's called was already
in the queue during the last call to GetMessage()/PeekMessage().
also now discarding screen saver events if there are any other
screen saver events in the queue already. this prevents these
events from piling up in the queue, which they'd do because we
sleep for 250ms when handling each one.
work but will let testers make the final call. also fixed
desktop synchronization by setting a variable that was
mistakenly left unset. and tried to work around an apparent
bug in MsgWaitForMultipleObjects() that prevented the service
from closing down properly. start/pause/continue/stop
sequence still doesn't shut down correctly. start/pause/stop
and start/stop work fine.
screens into CPrimaryScreen and merged common code from secondary
screens into CSecondaryScreen. changed is-a relationship to a
has-a between the primary and secondary screen classes and the
generic platform dependent screen class to avoid multiple
inheritance of implementation. also standardized the interface
for those generic screen classes. adding a platform now involves
implementing simpler interfaces: IScreen for the generic screen,
IScreenEventHandler and some methods of CPrimaryScreen for the
primary screen, and IScreenEventHandler and some methods of
CSecondaryScreen for the secondary screen. did X11 platform
but not win32 platform.
now speaks to the primary screen and secondary screens almost
everywhere the same way through an IClient interface; only
special primary screen calls are accessed through a different
interface, the CPrimaryClient interface. this simplifies the
server since it no longer needs to test whether the active screen
is the primary or a secondary in most cases.
the server no longer speaks directly to the primary screen; all
that goes through the CPrimaryClient, which often just forwards
the call. the primary screen no longer speaks directly to the
server either, again going through the CPrimaryClient via a
IPrimaryReceiver interface.
CServerProtocol classes have been replaced by CClientProxy
classes which are very similar. the name makes more sense
though.
activation. previously the timer would deactivate the screen
saver shortly after activation. job timer is restored when
the screen saver is deactivated.
installing and uninstalling the new error handler, causing
errors before the lock to be caught and errors during the lock
to not be caught. had to add Display* as argument to c'tor.
and untested. also some known problems: not detecting an
xscreensaver started after us and not detecting built-in
screen saver activation (not sure if we can without using
ugly extensions).
multiple times is *not* the same as calling XIfEvent() because the
former will re-encounter events that it didn't process previously.
to make things simple it now pulls events off the queue and saves
them if not processed for selection transfer and puts them back
afterwards.
when it wasn't necessary. (in particular, we were getting the
clipboard update time from the owner then emptying the clipboard,
so we didn't need to get the time. worse, most owners don't
support getting the time and we often timed out.)
also fixed a multithread bug using the X display. we were using
a CThread to send an event after a timeout while we were waiting
in XIfEvent(). this necessarily involved two threads calling
into Xlib at once, which is not allowed. now using polling to
do the timeout because Xlib doesn't have a function to get
events with a timeout.
