* libvncserver: Make RRE, CoRRE and Ultra encodings thread-safe.Christian Beier2011-02-076-159/+96
| | | | | | | This adds generic before/after encoding buffers to the rfbClient struct, so there is no need for thread local storage. Signed-off-by: Christian Beier <dontmind@freeshell.org>
* Remove unneeded files concerning CVS.Christian Beier2011-01-312-8/+0
| | | | | | We have a git repo nowadays and I guess we won't go back to CVS. Signed-off-by: Christian Beier <dontmind@freeshell.org>
* Put files used by both libs into a 'common' dir.Christian Beier2011-01-258-5019/+5
| | | | | | | | | No functional changes. All files used by _both_ libvncserver and libvncclient are put into a 'common' directory and references from other files as well as Autotools and CMake build systems are updated. Signed-off-by: Christian Beier <dontmind@freeshell.org>

* libvncserver sockets: check cl->screen before accessing itTobias Doerffel2010-12-011-2/+2
| | | | | | | | | In commit 079394ca5b14d8067b95a9cf95a834828b4425a6 new code with insufficient checks was introduced causing a segfault when doing a HTTP server connection. Such connections have no screen set in the client data structure. Signed-off-by: Tobias Doerffel <tobias.doerffel@gmail.com>

* libvnc[server|client]: implement xvp VNC extension.Christian Beier2010-11-023-2/+64
| | | | | | | This implements the xvp VNC extension, which is described in the community version of the RFB protocol: http://tigervnc.sourceforge.net/cgi-bin/rfbproto It is also mentioned in the official RFB protocol.
* Added missing initialization of extension mutexTobias Doerffel2010-10-291-0/+5
| | | | | | | | | | When not calling rfbRegisterProtocolExtension() the extension mutex is uninitialized but used upon calling rfbGetExtensionIterator() and rfbReleaseExtensionIterator() in rfbNewTCPOrUDPClient(). This causes libvncserver to crash on Win32 when building with thread support. Signed-off-by: Tobias Doerffel <tobias.doerffel@gmail.com> Signed-off-by: Christian Beier <dontmind@freeshell.org>

* Non-blocking sockets for Windows.Christian Beier2010-09-133-39/+31
| | | | | | | | | | | Expands the SetNonBlocking() function in libvncclient/sockets.c to also work under Windows and also changes it to honour maybe already present socket flags. A similar function was introduced for libvncserver as well and all the #ifdef'ed fnctl calls replaced with calls to that one. Signed-off-by: Christian Beier <dontmind@freeshell.org>
* Cleanup: remove CORBA stuff.Christian Beier2010-09-133-20/+1

* Fix MinGW32 compilation with libjpeg.Christian Beier2010-09-061-0/+3
| | | | | | | | | MinGW32 (or more exactly, a rpcndr.h file included by winsock2.h) typedefs a 'boolean' type that jmorecfg.h included by jpeglib.h also tries to typedef. So, tell the jpeg headers. Closes: 3007302
* Implement a DisplayFinishedHook for libvncserver.Christian Beier2010-05-192-1/+12
| | | | | | | If set, this hook gets called just before rfbSendFrameBufferUpdate() returns. Signed-off-by: Christian Beier <dontmind@freeshell.org>

* clean up build flagsdscho2009-02-031-1/+1
| | | | | | | | | | | | | | | | | The flag handling (both compiler options and include paths) are a mess at the moment. There is no point in forcing "-O2 -g" when these are already the defaults, and if someone changes the defaults, chances are good they don't want you clobbering their choices. The -Wall flag should be handled in configure and thrown into CFLAGS once rather than every Makefile.am. Plus, this way we can control which compilers the flag actually gets used with. Finally, the INCLUDES variable is for -I paths, not AM_CFLAGS. Nor should it contain -I. as this is already in the default includes setup.

* Fix Swap16IfLE() on bytesdscho2008-01-311-3/+3
| | | | | | | | | | When swapping the values for the colour table to little-endian (because they are 16-bit values), we need to cast "unsigned char" to "unsigned short"; otherwise, Microsoft's compiler would keep complaining. Noticed by Christian Ehrlicher. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
* Move tightQualityLevel out of the JPEG specific partdscho2008-01-311-2/+2
| | | | | | | | The variable tightQualityLevel is used for ZYWRLE compression, too, so if libjpeg is not present, but libz is, we still need to have that struct member. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
* Make ZYWRLE thread-safe for multiple clientsdscho2008-01-302-17/+15
| | | | | | | | ZYWRLE used a static buffer, which does not work too well if you have more than one client in a threaded server. Instead, we have the data in the client structure now. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
* ZYWRLE brown paper bag fixdscho2008-01-302-4/+6
| | | | | | | | | | While adjusting the coding style, three stupid mistakes happened. The quality is _not_ just 1, 2, 3, but really 1, 3, 2. And the macros ZYWRLE_PACK_COEFF() and ZYWRLE_UNPACK_COEFF() expand to more than one statement, which means that we need curly brackets around them when they are in an if clause.

* Fix a locking problem in libvncserverdscho2007-03-172-3/+2
| | | | | | | | | | | | | | | | | | | There seems to be a locking problem in libvncserver, with respect to how condition variables are used. On certain machines in our lab, when using a vncviewer to view a display that has a very high rate of updates, we will occasionally see the VNC server process crash. In one stack trace that was obtained, an assertion had tripped in glibc's pthread_cond_wait, which was called from clientOutput. Inspection of clientOutput suggests that WAIT is being called incorrectly. The mutex that protects a condition variable should always be locked when calling wait, and on return from the wait will still be locked. The attached patch fixes the locking around this condition variable, and one other that I found by grepping the source for similar occurrences. Signed-off-by: Charles Coffing <ccoffing@novell.com>
