This patch is the + result of further research and discussion that revealed the + following: -- TightPng encoding and the rfbTightNoZlib extension need not + conflict. Since TightPng is a separate encoding type, not supported + by TurboVNC-compatible viewers, then the rfbTightNoZlib extension + can be used solely whenever the encoding type is Tight and disabled + with the encoding type is TightPng. -- In the TightVNC encoder, compression levels above 5 are basically + useless. On the set of 20 low-level datasets that were used to + design the TurboVNC encoder (these include the eight 2D application + captures that were also used when designing the TightVNC encoder, as + well as 12 3D application captures provided by the VirtualGL + Project-- see + http://www.virtualgl.org/pmwiki/uploads/About/tighttoturbo.pdf), + moving from Compression Level (CL) 5 to CL 9 in the TightVNC + encoder did not increase the compression ratio of any datasets more + than 10%, and the compression ratio only increased by more than 5% + on four of them. The compression ratio actually decreased a few + percent on five of them. In exchange for this paltry increase in + compression ratio, the CPU usage, on average, went up by a factor of + 5. Thus, for all intents and purposes, TightVNC CL 5 provides the + "best useful compression" for that encoder. -- TurboVNC's best compression level (CL 2) compresses 3D and video + workloads significantly more "tightly" than TightVNC CL 5 (~70% + better, in the aggregate) but does not quite achieve the same level + of compression with 2D workloads (~20% worse, in the aggregate.) + This decrease in compression ratio may or may not be noticeable, + since many of the datasets it affects are not performance-critical + (such as the console output of a compilation, etc.) However, for + peace of mind, it was still desirable to have a mode that compressed + with equal "tightness" to TightVNC CL 5, since we proposed to + replace that encoder entirely. -- A new mode was discovered in the TurboVNC encoder that produces, + in the aggregate, similar compression ratios on 2D datasets as + TightVNC CL 5. That new mode involves using Zlib level 7 (the same + level used by TightVNC CL 5) but setting the "palette threshold" to + 256, so that indexed color encoding is used whenever possible. This + mode reduces bandwidth only marginally (typically 10-20%) relative + to TurboVNC CL 2 on low-color workloads, in exchange for nearly + doubling CPU usage, and it does not benefit high-color workloads at + all (since those are usually encoded with JPEG.) However, it + provides a means of reproducing the same "tightness" as the TightVNC encoder on 2D workloads without sacrificing any compression for + 3D/video workloads, and without using any more CPU time than + necessary. -- The TurboVNC encoder still performs as well or better than the + TightVNC encoder when plain libjpeg is used instead of + libjpeg-turbo. Specific notes follow: common/turbojpeg.c common/turbojpeg.h: Added code to emulate the + libjpeg-turbo colorspace extensions, so that the TurboJPEG wrapper + can be used with plain libjpeg as well. This required updating the + TurboJPEG wrapper to the latest code from libjpeg-turbo 1.2.0, + mainly because the TurboJPEG 1.2 API handles pixel formats in a much + cleaner way, which made the conversion code easier to write. It + also eases the maintenance to have the wrapper synced as much as + possible with the upstream code base (so I can merge any relevant + bug fixes that are discovered upstream.) The libvncserver version of + the TurboJPEG wrapper is a "lite" version, containing only the JPEG + compression/decompression code and not the lossless transform, YUV + encoding/decoding, and dynamic buffer allocation features from + TurboJPEG 1.2. configure.ac: Removed the --with-turbovnc option. configure still + checks for the presence of libjpeg-turbo, but only for the purposes + of printing a performance warning if it isn't available. rfb/rfb.h: Fix a bug introduced with the initial TurboVNC encoder + patch. We cannot use tightQualityLevel for the TurboVNC 1-100 + quality level, because tightQualityLevel is also used by ZRLE. + Thus, a new parameter (turboQualityLevel) was created. rfb/rfbproto.h: Remove TurboVNC-specific #ifdefs and language libvncserver/rfbserver.c: Remove TurboVNC-specific #ifdefs. Fix + afore-mentioned tightQualityLevel bug. libvncserver/tight.c: Replaced the TightVNC encoder with the + TurboVNC encoder. Relative to the initial TurboVNC encoder patch, + this patch also: -- Adds TightPng support to the TurboVNC encoder -- + Adds the afore-mentioned low-bandwidth mode, which is mapped + externally to Compression Level 9 test/*: Included TJUnitTest (a regression test for the TurboJPEG + wrapper) as well as TJBench (a benchmark for same.) These are + useful for ensuring that the wrapper still functions correctly and + performantly if it needs to be modified for whatever reason. Both + of these programs are derived from libjpeg-turbo 1.2.0. As with the + TurboJPEG wrapper, they do not contain the more advanced features of + TurboJPEG 1.2, such as YUV encoding/decoding and lossless + transforms. + +2012-03-15 Christian Beier + + * AUTHORS: Add DRC to AUTHORS. + +2012-03-15 Christian Beier + + * rfb/rfb.h: Move tightsubsamplevel member to the end of rfbClient + struct.

The issue is that, when using the current libvncserver source, it is + impossible to disable Tight JPEG encoding. The way Tight/Turbo + viewers disable JPEG encoding is by simply not sending the Tight + quality value, causing the server to use the default value of -1. + Thus, cl->tightQualityLevel has to be set to -1 prior to processing + the encodings message for this mechanism to work. Similarly, it is + not guaranteed that the compress level will be set in the encodings + message, so it is set to a default value prior to processing the + message. + +2012-03-10 DRC + + * common/turbojpeg.c, common/turbojpeg.h, configure.ac, + libvncserver/Makefile.am, libvncserver/rfbserver.c, + libvncserver/turbo.c, rfb/rfb.h, rfb/rfbproto.h: Add TurboVNC + encoding support. TurboVNC is a variant of TightVNC that uses the same client/server + protocol (RFB version 3.8t), and thus it is fully cross-compatible + with TightVNC and TigerVNC (with one exception, which is noted + below.) Both the TightVNC and TurboVNC encoders analyze each + rectangle, pick out regions of solid color to send separately, and + send the remaining subrectangles using mono, indexed color, JPEG, or + raw encoding, depending on the number of colors in the subrectangle. + However, TurboVNC uses a fundamentally different selection algorithm + to determine the appropriate subencoding to use for each + subrectangle. Thus, while it sends a protocol stream that can be + decoded by any TightVNC-compatible viewer, the mix of subencoding + types in this protocol stream will be different from those generated + by a TightVNC server. The research that led to TurboVNC is described in the following + report: + http://www.virtualgl.org/pmwiki/uploads/About/tighttoturbo.pdf. In + summary: 20 RFB captures, representing "common" 2D and 3D + application workloads (the 3D workloads were run using VirtualGL), + were studied using the TightVNC encoder in isolation. Some of the + analysis features in the TightVNC encoder, such as smoothness + detection, were found to generate a lot of CPU usage with little or + no benefit in compression, so those features were disabled. JPEG + encoding was accelerated using libjpeg-turbo (which achieves a 2-4x + speedup over plain libjpeg on modern x86 or ARM processors.) + Finally, the "palette threshold" (minimum number of colors that the + subrectangle must have before it is compressed using JPEG or raw) + was adjusted to account for the fact that JPEG encoding is now quite + a bit faster (meaning that we can now use it more without a CPU + penalty.) TurboVNC has additional optimizations, such as the + ability to count colors and encode JPEG images directly from the + framebuffer without first translating the pixels into RGB. The + TurboVNC encoder compares quite favorably in terms of compression + ratio with TightVNC and generally encodes a great deal faster (often + an order of magnitude or more.) The version of the TurboVNC encoder included in this patch is + roughly equivalent to the one found in version 0.6 of the Unix + TurboVNC Server, with a few minor patches integrated from TurboVNC + 1.1. TurboVNC 1.0 added multi-threading capabilities, which can be + added in later if desired (at the expense of making libvncserver + depend on libpthread.) Because TurboVNC uses a fundamentally different mix of subencodings + than TightVNC, because it uses the identical protocol (and thus a + viewer really has no idea whether it's talking to a TightVNC or + TurboVNC server), and because it doesn't support rfbTightPng (and in + fact conflicts with it-- see below), the TurboVNC and TightVNC + encoders cannot be enabled simultaneously. Compatibility: In *most* cases, a TurboVNC-enabled viewer is fully compatible with + a TightVNC server, and vice versa. TurboVNC supports + pseudo-encodings for specifying a fine-grained (1-100) quality scale + and specifying chrominance subsampling. If a TurboVNC viewer sends + those to a TightVNC server, then the TightVNC server ignores them, + so the TurboVNC viewer also sends the quality on a 0-9 scale that + the TightVNC server can understand. Similarly, the TurboVNC server + checks first for fine-grained quality and subsampling + pseudo-encodings from the viewer, and failing to receive those, it + then checks for the TightVNC 0-9 quality pseudo-encoding. There is one case in which the two systems are not compatible, and + that is when a TightVNC or TigerVNC viewer requests compression + level 0 without JPEG from a TurboVNC server. For performance + reasons, this causes the TurboVNC server to send images directly to + the viewer, bypassing Zlib. When the TurboVNC server does this, it + also sets bits 7-4 in the compression control byte to rfbTightNoZlib + (0x0A), which is unfortunately the same value as rfbTightPng. Older + TightVNC viewers that don't handle PNG will assume that the stream + is uncompressed but still encapsulated in a Zlib structure, whereas + newer PNG-supporting TightVNC viewers will assume that the stream is + PNG. In either case, the viewer will probably crash. Since most + VNC viewers don't expose compression level 0 in the GUI, this is a + relatively rare situation. Description of changes: configure.ac -- Added support for libjpeg-turbo. If passed an + argument of --with-turbovnc, configure will now run (or, if cross-compiling, just link) a test program that determines + whether the libjpeg library being used is libjpeg-turbo. + libjpeg-turbo must be used when building the TurboVNC encoder, + because the TurboVNC encoder relies on the libjpeg-turbo + colorspace extensions in order to compress images directly out of + the framebuffer (which may be, for instance, BGRA rather than RGB.) + libjpeg-turbo can optionally be used with the TightVNC encoder as + well, but the speedup will only be marginal (the report linked above + explains why in more detail, but basically it's because of Amdahl's + Law. The TightVNC encoder was designed with the assumption that + JPEG had a very high CPU cost, and thus JPEG is used only + sparingly.) -- Added a new configure variable, JPEG_LDFLAGS. This + is necessitated by the fact that libjpeg-turbo often distributes + libjpeg.a and libjpeg.so in /opt/libjpeg-turbo/lib32 or + /opt/libjpeg-turbo/lib64, and many people prefer to statically + link with it. Thus, more flexibility is needed than is provided by + --with-jpeg. If JPEG_LDFLAGS is specified, then it overrides the + changes to LDFLAGS enacted by --with-jpeg (but --with-jpeg is + still used to set the include path.) The addition of JPEG_LDFLAGS + necessitated replacing AC_CHECK_LIB with AC_LINK_IFELSE (because + AC_CHECK_LIB automatically sets LIBS to -ljpeg, which is not what we + want if we're, for instance, linking statically with libjpeg-turbo.) + -- configure does not check for PNG support if TurboVNC encoding is + enabled. This prevents the rfbSendRectEncodingTightPng() function + from being compiled in, since the TurboVNC encoder doesn't (and + can't) support it. common/turbojpeg.c, common/turbojpeg.h -- TurboJPEG is a simple API + used to compress and decompress JPEG images in memory. It was + originally implemented because it was desirable to use different + types of underlying technologies to compress JPEG on different + platforms (mediaLib on SPARC, Quicktime on PPC Macs, Intel + Performance Primitives, etc.) These days, however, libjpeg-turbo + is the only underlying technology used by TurboVNC, so TurboJPEG's + purpose is largely just code simplicity and flexibility. Thus, + since there is no real need for libvncserver to use any technology + other than libjpeg-turbo for compressing JPEG, the TurboJPEG wrapper + for libjpeg-turbo has been included in-tree so that libvncserver can + be directly linked with libjpeg-turbo. This is convenient because + many modern Linux distros (Fedora, Ubuntu, etc.) now ship + libjpeg-turbo as their default libjpeg library. libvncserver/rfbserver.c -- Added logic to check for the TurboVNC + fine-grained quality level and subsampling encodings and to map + Tight (0-9) quality levels to appropriate fine-grained quality level + and subsampling values if communicating with a TightVNC/TigerVNC + viewer. libvncserver/turbo.c -- TurboVNC encoder (compiled instead of + libvncserver/tight.c) rfb/rfb.h -- Added support for the TurboVNC subsampling level rfb/rfbproto.h -- Added constants for the TurboVNC fine quality + level and subsampling encodings as well as the rfbTightNoZlib + constant and notes on its usage. + +2012-03-10 Christian Beier + + * client_examples/SDLvncviewer.c, libvncclient/listen.c, + libvncclient/sockets.c, libvncclient/vncviewer.c, + libvncserver/sockets.c, rfb/rfbclient.h: IPv6 support for + LibVNCServer, part three: make reverse connections IPv6-capable.

Lengthy explanation follows... First, the scenario before this patch: We have three clients 1,2,3 connected. The main thread loops through + them using rfbClientIteratorNext() (loop L1) and is currently at + client 2 i.e. client 2's cl_2->refCount is 1. At this point we need + to loop again through the clients, with cl_2->refCount == 1, i.e. do + a loop L2 nested within loop L1. BUT: Now client 2 disconnects, it's clientInput thread terminates + its clientOutput thread and calls rfbClientConnectionGone(). This + LOCKs clientListMutex and WAITs for cl_2->refCount to become 0. This + means this thread waits for the main thread to release cl_2. + Waiting, with clientListMutex LOCKed! Meanwhile, the main thread is about to begin the inner + rfbClientIteratorNext() loop L2. The first call to + rfbClientIteratorNext() LOCKs clientListMutex. BAAM. This mutex is + locked by cl2's clientInput thread and is only released when + cl_2->refCount becomes 0. The main thread would decrement + cl_2->refCount when it would continue with loop L1. But it's waiting + for cl2's clientInput thread to release clientListMutex. Which never + happens since this one's waiting for the main thread to decrement + cl_2->refCount. DEADLOCK. Now, situation with this patch: Same as above, but when client 2 disconnects it's clientInput thread + rfbClientConnectionGone(). This again LOCKs clientListMutex, removes + cl_2 from the linked list and UNLOCKS clientListMutex. The WAIT for + cl_2->refCount to become 0 is _after_ that. Waiting, with + clientListMutex UNLOCKed! Therefore, the main thread can continue, do the inner loop L2 (now + only looping through 1,3 - 2 was removed from the linked list) and + continue with loop L1, finally decrementing cl_2->refCount, allowing + cl2's clientInput thread to continue and terminate. The resources + held by cl2 are not free()'d by rfbClientConnectionGone until + cl2->refCount becomes 0, i.e. loop L1 has released cl2. + +2011-10-16 Johannes Schindelin + + * AUTHORS: Update AUTHORS Signed-off-by: Johannes Schindelin + +2011-10-16 George Fleury + + * libvncserver/rfbserver.c: Fix memory leak I was debbuging some code tonight and i found a pointer that is not + been freed, so i think there is maybe a memory leak, so it is... there is the malloc caller reverse order: ( malloc cl->statEncList ) <- rfbStatLookupEncoding <- rfbStatRecordEncodingSent <- rfbSendCursorPos <- rfbSendFramebufferUpdate <- rfbProcessEvents I didnt look the whole libvncserver api, but i am using + rfbReverseConnection with rfbProcessEvents, and then when the client + connection dies, i am calling a rfbShutdownServer and + rfbScreenCleanup, but the malloc at rfbStatLookupEncoding isnt been + freed.
