This is a very simple + encoder removing the 4th byte in 32 bits-per-plane images. For + the other pixmap depths it simply returns a pointer to the orig- + inal image data, saving the copy. This encoding is intended to + better leverage the stream compression on low bandwidth links. + +- Removed the quality parameter from the RGB/RLE encoding function. + +nxcompext-3.0.0-11 + +- Removed the additional parameter in the call to NXTransFlush(). + +nxcompext-3.0.0-10 + +- Moved the _NXRDPGlyph and _NXRDPText declarations from NXlib.h + to NXproto.h to force fields to be CARD32. + +- Fixed a typo in NXSetDisplayBuffer() that could cause a double + free. + +- Fixed a compilation error with old GCC versions. + +- Removed the warning issued on AMD64 when compiling with the logs + enabled. + +nxcompext-3.0.0-9 + +- Added the NXDisplayCongestion query type to NXQueryDisplay().

The alpha data is compressed using the + ZLIB RLE encoding, while the colormap data is compressed using + the default ZLIB deflate. + +- Created new message structures to handle the compatibility with + the old proxy versions. When connected to an old proxy version + the agent should use the NXSetUnpackColormapCompat() and NXSet- + UnpackAlpha() interfaces. + +nxcompext-2.0.0-30 + +- Removed the unfriendly warning printed if a client tried to reset + the library multiple times. + +nxcompext-2.0.0-29 + +- Made possible to compile even if makedepend is not found. + +nxcompext-2.0.0-28 + +- Added the NXSetDisplaySynchronizationHandler() interface. The NX + transport will use the callback to report when the agent can use + the available bandwidth to synchronize the X objects that are + corrupted or incomplete. + +- Bytes from 14 to 24 in the NXGetControlParameters() reply report, + respectively, the frame timeout, the ping timeout, the preferred + image split mode and the split size threshold. + +nxcompext-2.0.0-27 + +- Changed the image cleanup functions and the Png and Jpeg encoders + to be independent from the host endianess. + +- Enabled again the image cleanup on big endian machines. + +nxcompext-2.0.0-26 + +- Added the NXAbortSplit() request. + +- Added information about the size of the shared memory segment used + by the remote proxy in the NXGetShmemParameters() reply. + +nxcompext-2.0.0-25 + +- Renamed the NXGetSplitResource() and NXGetUnpackResource() utili- + ties to NXAllocSplit() and NXAllocUnpack(). They can be called + with a NXAnyResource parameter to get the first available id or + requre a specific resource. From this version the resource must + be explicitly reserved. NXFreeUnpack() and NXFreeSplit() check + if the resource was allocated and don't do anything if it is not + the case. NXAllocSplit() and NXAllocUnpack() return NXNoResource + if the resource can't be reserved. + +nxcompext-2.0.0-24 + +- NXFlushDisplay() now verifies whether the XlibDisplayWriting flag + is set before flushing the display buffer. in this case, it only + flushes the NX link. + +nxcompext-2.0.0-23 + +- Implemented a move-to-front strategy for the image cache, to mi- + nimize the number of lookups. + +- Fixed the problems imtroduced by the new cache implementation by + modifying the memory allocation routines in Jpeg.c and Pgn.c. + +- Temporarily fixed the cleanup problems on big-endian machines by + skipping the operation. + +- Added a NXSetDisplayStatisticsHandler() to let the agent include + arbitrary data in the transport statistics. The parameter is a + pointer to a pointer to a null terminated string. The pointer is + set at the time the handler is registered. The pointed string can + be filled by the agent with its statistics data. + +nxcompext-2.0.0-22 + +- The NXCacheFindImage() returns a pointer to the checksum, if the + image is found. + +- The image cache uses the data passed to NXCacheAddImage() instead + of making a copy. + +- The Z stream used by the RGB encoder is allocated at initializat- + ion and freed at reset. + +nxcompext-2.0.0-21 + +- Removed the reliance on the local byte order in the image cleanup + functions. + +nxcompext-2.0.0-20 + +- Added the NXFinishSplit() request. It forces the proxy to comple- + tely transfer all the split messages for the given resource, and + then notify the agent. + +nxcompext-2.0.0-19 + +- Enabled again the cleanup of images. + +- Updated to comply with the new NXTransFlush() interface. + +nxcompext-2.0.0-18 + +- Moved all the declarations in Rgb.c at the beginning of the block + to avoid the possible compilation errors with old compilers. + +nxcompext-2.0.0-17 + +- Added a new RGB image encoder. For now the encoder uses a static + Z stream to compress the image data in the destination buffer and + allows the agent to use the simplest encoding by still separating + the alpha channel from the image data. The new encoder can be the + the base for implementing color reduction by dithering or a color- + mapped translation of the image similar to PNG, but without the + PNG overhead and with the colormap being sent to the client using + the NXSetUnpackColormap() opcode. + +- Created a new NXCleanImage() function that takes a XImage pointer + and uses either the CleanXYImage() or the CleanZImage() routines + to cleanup the padding bits. + +nxcompext-2.0.0-16 + +- Added a parameter to NXFlushDisplay() to specify what needs to be + flushed. The parameter can be one the following values, defined + in NXvars.h: + + NXFlushBuffer Only the Xlib buffer is to be flushed. + + NXFlushLink Flush both the Xlib buffer and any pending + data encoded by the NX transport. + + NXFlushIdle Inform the NX transport that the agent is + idle. This will let the NX transport encode + more low-priority data, and then flush the + link. + +- Ensured that the padding bytes are cleaned when creating a new + PNG image. It seems that some images are still missed. This is + to be investigated. + +nxcompext-2.0.0-15 + +- Ensured that the packed image cache is recreated only on a size + change. + +nxcompext-2.0.0-14 + +- Updated to get the karma delay field from the X_NXGetControlPara- + meters reply. + +nxcompext-2.0.0-13 + +- Added the NXSetDisplayPolicy() and NXSetDisplayFlushHandler() in- + terfaces. The second function registers a callback that will be + invoked by the NX transport when the number of bytes encoded by + the proxy exceeds the threshold set for the scheduled write. + +- Added the NXFlushDisplay() and NXQueryDisplay() interfaces. They + are used to hide the corresponding NX transport functions to the + application. NXQueryDisplay() can be called with the NXDisplay- + Flushable or NXDisplayReadable parameters, to get, repectively, + the number of bytes that are queued to the NX transport and the + number of bytes that is possible to read. + +- Included the remote proxy version in the NXGetControlParameter() + reply. + +nxcompext-2.0.0-12 + +- Added the NXGetSplitResource() and NXGetUnpackResource utilities. + These can be used by the client to find out the first unused id + available for a split or unpack operation. + +- Added the NXFreeSplit() request function. It makes the resource + available for the next operation and tells the proxy to destroy + all the storage associated to the split. + +- Renamed the NXNumberOfConnections constant to NXNumberOfResources. + +nxcompext-2.0.0-11 + +- Changed NXForceDisplayError() to also shut down the NX transport + by calling NXTransClose(). + +- Updated to comply with the new NX function prototypes introduced + in nxcomp-2.0.0-31. + +nxcompext-2.0.0-10 + +- NXQueryDisplayError() now checks the predicate function only if + the I/O error was not encountered already. + +nxcompext-2.0.0-9 + +- Added the NXSetDisplayErrorPredicate(), NXSetDisplayBlockHand- + ler(), NXSetDisplayCongestionHandler(), NXSetLostSequenceHand- + ler() interfaces to let the user set the values used internal- + ly. All functions return the previous handler. See ChangeLog + in nx-X11-2.0.0-16 and nx-X11-2.0.0-17. + +- Moved all the internal variables shared between Xlib, nxcompext + and the X server in nxcomp. Declarations and function prototypes + moved to NXvars.h. + +- Some name changes. In particular the NXContinueOnDisplayError() + function iss renamed NXHandleDisplayError() and NXDisplayError() + is now renamed NXQueryDisplayError(). To verify if the display + is valid, NXQueryDisplayError() will now call the _NXDisplayEr- + rorPredicate function, or, if the predicate function is not set, + will simply check the value of the XlibDisplayIOError flag. + +- Removed the NXGetCleanupParameters() and NXGetImageParameters() + interfaces and the remaining references to the unused display + buffer and image cleanup functions. + +- Updated the NoMachine copyright notice to year 2006. + +nxcompext-2.0.0-8 + +- Removed the unused screen parameter from XSetUnpackGeometry(). + +- NXSetUnpackGeometry() now fails if no visual is provided. + +nxcompext-2.0.0-7 + +- Changed the LICENSE file to state that the software is only made + available under the version 2 of the GPL. + +- Removed the misplaced DXPC copyright notices from the license. + They were copied from NXCOMP but they don't apply in any way to + NXCOMPEXT. + +nxcompext-2.0.0-6 + +- Added the NXSetCacheParameters() request. It tells to the local + proxy how to handle the X requests, namely if the next requests + have to be stored in the memory cache, split in smal data chunks, + and in the case of images, saved on disk in the persistent image + cache. The request will affect all X messages, including plain + and packed images. It can be used to tell the proxy to discard + images coming from some selected operations, like GLX or XVideo. + +nxcompext-2.0.0-5 + +- Added the NXGetFontParameters() request and reply. If the proxy + has been configured accordingly, the request returns the X font + path that can be set by the agent to tunnel the font server con- + nections through the NX link. + +nxcompext-2.0.0-4 + +- Initial work on font server tunneling. + +nxcompext-2.0.0-3 + +- Renamed the NXSetExposeEvents request to NXSetExposeParameters. + +nxcompext-2.0.0-2 + +- Modified the configure and the makefiles to support the Cygwin + environment. + +- Renamed Png.h to Pgn.h to avoid name clashes on Windows. + +- The distclean target now removes the autom4te.cache directory. + +nxcompext-2.0.0-1 + +- Opened the 2.0.0 branch based on nxcompext-1.5.0-20. + +nxcompext-1.5.0-20 + +- Removed the code installing a SIGSEGV handler before trying to + clean an image in NXCleanImageInPlace(). + +nxcompext-1.5.0-19 + +- Added the NXUnsetLibraryPath() function to specify the behaviour + of the Popen() in the X server. If the _NXUnsetLibraryPath flag + is set, the Popen() will remove the LD_LIBRARY_PATH variable from + the environment before running the child process. This will cause + the X server to run the process (for example the keyboard initia- + lization utilities) by using the native system libraries, instead + of the libraries shipped with the NX environment. + +nxcompext-1.5.0-18 + +- Moved the declarations of _NXEnable* and related structures from + Xlibint.h to NXlibint.h. + +- Use the include files from nx-X11 if the nx-X11/include directory + is found. The previous configure checked the presence of nx-X11/ + exports/include, that might not be built at the time this library + is compiled. + +nxcompext-1.5.0-17 + +- Added the -fPIC GCC flag when compiling on AMD64 architectures. + +- Removed all warnings when compiling with GCC4. + +- Small changes to configure.in to have specific CFLAGS. + +- Created a new configure using autoconf 2.59. + +nxcompext-1.5.0-16 + +- Added the 'mode' field in the NXStartSplit() request. It determi- + nes the strategy that the proxy will adopt to handle the image. + If set to 'eager', the proxy will only split the messages whose + size exceeds the split threshold (the threshold can be found in + the NXGetControlParameters() reply). If mode is set to lazy, the + proxy will split any image that it is not able to find in its + cache. + + The opcode and the two available modes are defined in NXproto.h, + currently: + + #define NXSplitModeDefault 0 + #define NXSplitModeEager 1 + #define NXSplitModeLazy 2 + +- All requests related to image streaming now carry a 'resource' id. + The id is currently ignored by the proxy in the case of NXCommit- + Split() requests. + +nxcompext-1.5.0-15 + +- Removed the NXSync() and NXKarma() operations, not used anymore + by the NX agents. + +- Updated to comply with changes occurred in the numbering of the + notification events and in the interface to the image streaming + functions. + +nxcompext-1.5.0-14 + +- Accounted for the missing xoffset field in clean-up of XYPixmaps. + +nxcompext-1.5.0-13 + +- Added a 'commit' field in NXCommitSplit(). When zero, the remote + proxy will remove the message from the split store, without send- + ing the recomposed image to the X server. + +nxcompext-1.5.0-12 + +- Added the NXContinueOnDisplayError() function to specify the be- + haviour of the Xlib I/O error handler. If the flag is set to true, + Xlib will simply return, instead of quitting the program. This + leaves to the application the responsibility of checking the sta- + te of the XlibDisplayIOError flag. + +- Changed NXDisplayIsValid() to NXDisplayError() and inverted the + logic. Now the function returns true if the display pointer is + NULL or the XlibDisplayIOError flag is set. + +- Added the NXForceDisplayError() function, to shutdown the display + descriptor and force Xlib to set the I/O error flag. + +nxcompext-1.5.0-11 + +- Added -I../nx-X11/exports/include to CCINCLUDES in Makefile.in. + +nxcompext-1.5.0-10 + +- Added FindLSB() to replace ffs() that may be not present on some + systems. + +- Some cosmetic changes. + +nxcompext-1.5.0-9 + +- Fixed a printf() that prevented the code to compile if TEST was + enabled. + +nxcompext-1.5.0-8 + +- Implemented the NXLib interface for asynchronous handling of the + XGetInputFocus requests and replies. + +nxcompext-1.5.0-7 + +- Removed the _NXFlushSize parameter. New agents run the NX trans- + port in-process, so we don't get any benefit from increasing the + display buffer size. + +nxcompext-1.5.0-6 + +- Added a NXDisplayIsValid() to check that the display is not NULL + and that the descriptor was not shut down after an IOError. The + reason a function is needed for this is that the flags field is + only in Xlibint and it is not visible to Xlib applications. + +nxcompext-1.5.0-5 + +- Added the NXGetCollect*Resource utility functions, returning the + first available small integer resource id that can be used in a + subsequent collect request. + +nxcompext-1.5.0-4 + +- Added the NXNumberOfConnections constant. + +nxcompext-1.5.0-3 + +- Implemented the NXLib interface for the asynchronous handling of + the XGrabPointer requests and replies. + +- Solved an error in image cleaning that prevented the 8 bits-per- + pixel images to be completely cleaned. Due to the bug, only half + of the total lines were cleaned. + +- Removed a bug that prevented the cleaning of XYPixmaps images of + bitmap unit 32 and byte order LSB. + +- Renamed the NXImageCache variables to show they are global. They + are currently used in the nxagent code. + +nxcompext-1.5.0-2 + +- Changed VERSION file. + +nxcompext-1.5.0-1 + +- Opened the 1.5.0 branch. + +nxcompext-1.4.1-1 + +- Removed the configure option --with-static. There are two options + now, --with-static-png and --with-static-jpeg, to offer a greater + degree of control on the resulting library. + +- This version differs from the 1.4.0-3-KRY1 in the way that the con- + figure script is generated by GNU Autoconf 2.57, the same version + used for nxcomp. + +- Opened the 1.4.1 branch. + +nxcompext-1.4.0-3 + +- Updated the VERSION file to reflect the 1.4.0 status. + +nxcompext-1.4.0-2 + +- Imported changes from the latest 1.3.2 development branch. + +- The 1.4.0 branch already had a 1.4.0-1 version. The changes from + the 1.4.0-1 were up to date with the 1.3.2-2 version. + +nxcompext-1.3.2-6 + +- Fixed problem with icons in KDE and Mozilla on SPARC Solaris. The + problem was related to cleaning of one-bit XYPixmaps on big-endian + hosts, where shift of the cleaning mask executed in the wrong di- + rection. + +nxcompext-1.3.2-5 + +- Changes in Clean.c to compile on Solaris. + +nxcompext-1.3.2-4 + +- Fixed a bug in clean image procedures for 1bit XYPixmaps. The bug + caused Mozilla to trash some transparent icons in web pages and + the toolbar. + +- Added cleaning of the padding bytes at the end of the data chunk + inside XImage structure + +- Implemented handling of SIGSEGV during cleanup in case of static + data. + +- Moved image cleanup and masking code in new Clean.c and Mask.c + sources. + +- Corrected few typos in NXCollectImage code. + +nxcompext-1.3.2-2 + +- Imported 1.4.0-1 changes from the 1.4.0 development branch. + +- Modified NXAllocColors to handle errors generated allocating + each requested color. A per-color result code is now returned + to the caller. + +- Code cleanup in Png.h and Png.c. + +nxcompext-1.3.2-1 + +- Opened the 1.3.2 branch. + +nxcompext-1.3.1-2 + +- Removed the underline characters and added a colon in the + title of this ChangeLog to fully comply with format used in + the release notices. + +nxcompext-1.3.1-1 + +- Opened the 1.3.1 branch. + +nxcompext-1.3.0-18 + +- Added the _NXLostSequenceHandler function to let NX agents + suppress the error message and modify the default Xlib + behaviour when out-of-order sequence numbers are received. + Pointer to function is assigned to _NXLostSequenceFunction + in XlibInt.c. + +- Original output buffer size in stock XFree86 is 2048. We try + to reduce context switches and help stream compression by + increasing the maximum size of the buffer 8192. _NXFlushSize + determines when the display buffer is actually flushed. It is + set by default to 4096 in XlibInt.c and set to 0 to use the + maximum available size at the time NXGetControlParameters() + is called. + +nxcompext-1.3.0-17 + +- In handling of asynchronous GetProperty replies a warning + message was printed in session log when a null property was + stored in the state structure. This message is now printed + only if TEST is defined. + +nxcompext-1.3.0-16 + +- Added asynchronous handling of GetProperty request and reply + by means of the NXCollectProperty and NXGetCollectedProperty + requests and the NXCollectPropertyNotify event. + +nxcompext-1.3.0-15 + +- Added 4 new fields to the X_NXGetControlParameters reply. + +nxcompext-1.3.0-14 + +- Added request X_NXFreeUnpack to free the resources allocated + by the remote proxy to unpack images for the given agent's + client + +nxcompext-1.3.0-13 + +- Modified the following requests to carry the id of the + agent's client in the field resource: + + - X_NXSetUnpackGeometry + - X_NXSetUnpackColormap + - X_NXSetUnpackAlpha + - X_NXPutPackedImage + +nxcompext-1.3.0-11 + +- Modified the MIT-SHM initialization procedure to always send + all the 3 protocol requests also in the case of early failures. + +nxcompext-1.3.0-10 + +- Added handling of X_NXSetUnpackAlpha request. + +- It has been made possible to send both X_NXSetUnpackColormap + and X_NXSetUnpackAlpha messages with 0 entries to temporarily + disable use of the colormap or the alpha channel and free the + resources allocated by the remote proxy. + +nxcompext-1.3.0-9 + +- Solved a compatibility problem when mixing proxy versions + 1.2.2 and 1.3.0 due to the missing X_NXGetShmemParameters + request. + +nxcompext-1.3.0-7 + +- Reduced the number of requests needed to setup the shared + segment at X server proxy from 4 to 3. + +- Small changes to the shared memory interface to support + path X agent to X client proxy. + +nxcompext-1.3.0-6 + +- Implemented initial support for MIT-SHM extension in the + network path between the X server proxy and the real X + server. + +- Configure script now checks for the FreeBSD environment. + +- New configure script generated using autoconf-2.57-3. + +- Removed the XFree86 CCDEFINES from Makefile.in. + +nxcompext-1.3.0-5 + +- Cosmetic changes. + +- Started to convert configure.in to the new layout adopted + for nxcomp. + +- Created file CHANGELOG. + +nxcompext-1.3.0-4 + +- More fixes in image clean-up. + +nxcompext-1.3.0-3 + +- Many fixes in image clean-up functions to handle differences + in endianess between client and X server. + +nxcompext-1.3.0-2 + +- Modified configure.in to compile under Solaris. + +nxcompext-1.3.0-1 + +- First 1.3.0 version based on nxcompext-1.2.2-12. + diff --git a/nx-X11/COPYING b/nxcompext/COPYING similarity index 100% copy from nx-X11/COPYING copy to nxcompext/COPYING diff --git a/nxcompext/Clean.c b/nxcompext/Clean.c new file mode 100644 index 0000000..cc02200 --- /dev/null +++ b/nxcompext/Clean.c @@ -0,0 +1,341 @@ +/**************************************************************************/ +/* */ +/* Copyright (c) 2001, 2007 NoMachine, http://www.nomachine.com/. */ +/* */ +/* NXCOMPEXT, NX protocol compression and NX extensions to this software */ +/* are copyright of NoMachine.

An image can be streamed + * by sending a start-split message, followed by the X messages + * that will have to be split by the proxy, followed by an end- + * split closure. Usually, in the middle of a start-split/end- + * split sequence there will be a single PutImage() or PutPack- + * edImage(), that, in turn, can generate multiple partial + * requests, like a SetUnpackColormap() and SetUnpackAlpha() + * that will be later used to decompress the image to its ori- + * ginal form. Multiple requests may be also generated because + * of the maximum size of a X request being exceeded, so that + * Xlib has to divide the single image in multiple sub-image re- + * quests. The agent doesn't need to take care of these details + * but will rather have to track the result of the split opera- + * tion. By monitoring the notify events sent by the proxy, the + * agent will have to implement its own strategy to deal with + * the resources. For example, it will be able to: + * + * - Mark a drawable as dirty, if the image was not sent + * synchronously, in the main X oputput stream. + * + * - Choose to commit or discard the original image, at the + * time it will be recomposed at the remote side. This may + * include all the messages that were part of the split + * (the colormap, the alpha channel, etc.) + * + * - Mark the drawable as clean again, if the image was + * committed and the drawable didn't change in the mean- + * while. + * + * At the time the proxy receives the end-split, it reports the + * result of the operation to the agent. The agent will be able + * to identify the original split operation (the one referenced + * in the start-split/end-split sequence) by the small integer + * number (0-255) named 'resource' sent in the events. + * + * One of the following cases may be encountered: + * + * + * NXNoSplitNotify All messages were sent in the main out- + * put stream, so that no split actually + * took place. + * + * NXStartSplitNotify One or more messages were split, so, + * at discrection of the agent, the client + * may be suspended until the transferral + * is completed. + * + * NXCommitSplitNotify One of the requests that made up the + * split was recomposed. The agent should + * either commit the given request or tell + * the proxy to discard it. + * + * NXEndSplitNotify The split was duly completed. The agent + * can restart the client. + * + * NXEmptySplitNotify No more split operation are pending. + * The agent can use this information to + * implement specific strategies requiring + * that all messages have been recomposed + * at the remote end, like updating the + * drawables that were not synchronized + * because of the lazy encoding. + * + * The 'mode' field that is sent by the agent in the start-split + * request, determines the strategy that the proxy will adopt to + * deal with the image. If set to 'eager', the proxy will only + * split the messages whose size exceeds the split threshold (the + * current threshold can be found in the NXGetControlParameters() + * reply). If the mode is set to lazy, the proxy will split any + * image that would have generated an actual transfer of the data + * part (in practice all images that are not found in the cache). + * This second strategy can be leveraged by an agent to further + * reduce the bandwidth requirements. For example, by setting the + * mode to lazy and by monitoring the result, an agent can easi- + * ly verify if the drawable was successfully updated, mark the + * drawable if not, and synchronize it at later time. + * + * See NXproto.h for the definition of the available modes. + */ + +extern unsigned int NXAllocSplit( +#if NeedFunctionPrototypes + Display* /* display */, + unsigned int /* resource */ +#endif +);
