* websockets: Add UTF-8 encoding support.Joel Martin2011-08-172-46/+88
| | | | | | | | | | | | | | | This is not completely standard UTF-8 encoding. Only code points 0-255 are encoded and never encoded to more than two octets. Since '\x00' is a WebSockets framing character, it's easier for all parties to encode zero as '\xc4\x80', i.e. 194+128, i.e. UTF-8 256. This means that a random stream will be slightly more than 50% larger using this encoding scheme. But it's easy CPU-wise for client and server to decode/encode. This is especially important for clients written in languages that have weak bitops, like Javascript (i.e. the noVNC client). Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
* websockets: Better disconnect detection.Joel Martin2011-08-171-0/+5
| | | | | | | If the only thing we are waiting on is a WebSockets terminator, then remove it from the stream early on in rfbProcessClientNormalMessage. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
* websockets: Initial WebSockets support.Joel Martin2011-08-176-2/+1164
| | | | | | | | | | | | | | Has a bug: WebSocket client disconnects are not detected. rfbSendFramebufferUpdate is doing a MSG_PEEK recv to determine if enough data is available which prevents a disconnect from being detected. Otherwise it's working pretty well. [jes: moved added struct members to the end for binary compatibility with previous LibVNCServer versions, removed an unused variable] Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

| | | | | | This reverts commit c1363fa9583ed41b94fbc79b3ff410b7d5189407. The proper fix was already in 804335f9d296440bb708ca844f5d89b58b50b0c6.

* Update minilzo library used for Ultra encoding to ver 2.04.Christian Beier2011-02-261-1/+1
| | | | | | | | | | According to the minilzo README, this brings a significant speedup on 64-bit architechtures. Changes compared to old version 1.08 can be found here: http://www.oberhumer.com/opensource/lzo/lzonews.php Signed-off-by: Christian Beier <dontmind@freeshell.org>

| | | | | | | 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>

* 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>

| | | | | | | | | 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

* 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.
