Export the declaration in + dixstruct.h. + +nx-X11-3.0.0-30 + +- The OsVendorVErrorFFatal flag is set to 1 if the function pointed + by OsVendorVErrorFProc is called due to a fatal error. + +- Give the possibility to the agent to redirect the standard error + during a Popen() or a System() by setting the OsVendorStartRedir- + ectErrorFProc and OsVendorEndRedirectErrorFProc function pointers. + +nx-X11-3.0.0-29 + +- Changed the default message printed on a fatal server error. The + new message is: + + Error: Aborting session with 'Error text...'. + +- Hacked LogVWrite() to force all fatal error messages to have an + uppercase initial.

Freetype is built as a shared + library: this avoids the link error on 64 bit platforms. + +nx-X11-3.0.0-26 + +- Applied the following security patches, from the X.Org security + advisory, April 3rd, 2007 "Multiple vulnerability in X server, + libXfont and libX11": + + xorg-xserver-1.2.0-xcmisc.diff + xorg-libXfont-1.2.7-bdf-fontdir.diff + xorg-libX11-1.1.1-xinitimage.diff + +nx-X11-3.0.0-25 + +- Added the missing *.X.original file for ChkIfEv.c and Xlib.h. + +nx-X11-3.0.0-24 + +- Changed Xrender to clean up the padding bytes in XRenderComposite- + Text functions. + +- Added function XRenderCleanGlyphs() cleaning the padding bytes in + the data section of RenderAddGlyphs requests. + +nx-X11-3.0.0-23 + +- Removed the additional parameter from the call to NXTransFlush() + in _XReply(). + +- Call NXTransExit() on AbortServer() (called by FatalError()) to + give the proxy a chance to shut down the NX transport. + +nx-X11-3.0.0-22 + +- Moved the replacement of XCheckIfEvent() ChkIfEv.c with the name + XCheckIfEventNoFlush(). + +nx-X11-3.0.0-21 + +- Set BUFSIZE to 8192 bytes. While the output buffer size can be + configured by setting the XLIBBUFFERSIZE in the environment (see + OpenDis.c), this constant is still used when reading from the + socket. + +nx-X11-3.0.0-20 + +- If set, the handler pointed by _NXDisplayWriteFunction is called + after that more data is written to the display connection. + +nx-X11-3.0.0-19 + +- Added a RejectWellKnownSockets() stub to make possible to compile + the agent when the NX transport is disabled. + +- Added more useful logs to _XWaitForWritable(). + +nx-X11-3.0.0-18 + +- Changed Imakefile of X11 and Xserver in order to build nxcompshad + just before the NX agent server. + +- Changed Imakefile in Xserver to add NXdamage.o to NXAGENTOBJS. + +nx-X11-3.0.0-17 + +- Changed host.def in order to build Xdamage and Xrandr libraries. + +- Changed host.def in order not to build NXWin. + +nx-X11-3.0.0-16 + +- Changed host.def in order to build Xtst as a shared library. + +nx-X11-3.0.0-15 + +- Changes to comply with nxcompshad library. + +- Changed configuration to statically build Xtst library. + +- Restored parser directory under Xserver/hw/xfree86. + +nx-X11-3.0.0-14 + +- Changed the LICENSE file to state that the software is only made + available under the version 2 of the GPL. + +- Added file COPYING. + +- In nx-X11/programs and nx-X11/programs/Xserver/hw/xfree86, removed + files and directories not needed to build servers. + +nx-X11-3.0.0-13 + +- Changes aimed to link servers with static versions of Xdmcp and Xau + libraries. + +nx-X11-3.0.0-12 + +- Added references to implented FR in the ChangeLog. + +- Removed nx-X11/fonts and nx-X11/doc directories. They are not needed + for building the NX components. + +nx-X11-3.0.0-11 + +- Updated the copyright notices to year 2007. + +nx-X11-3.0.0-10 + +- Applied the following security patches: + + x11r6.9.0-cidfonts.diff + x11r6.9.0-dbe-render.diff + x11r6.9.0-geteuid.diff + x11r6.9.0-mitri.diff + x11r6.9.0-setuid.diff + +nx-X11-3.0.0-9 + +- Merged the NX changes to X11 with the X11R6.9.0 version of X.org. + +nx-X11-3.0.0-8 + +- Changes to build Xshadow library when building X11. + +- Changes to Xserver Imakefile to link Xshadow library. + +- Changes to host.def in order to build on old distributions. + +nx-X11-3.0.0-7 + +- Imported changes up to nx-X11-2.1.0-2 + +- Fixed TR08D01485. Updated rgb file paths validation in order to + support Ubuntu distribution. + +- Added Xtst to libraries to be linked by nxagent. + +- Changed Xpm Imakefile to build a shared library on Solaris. + +- Fixed build error on Solaris in xtrans. + +- Changed host.def not to build Xnest server. + +- Changed Xserver Imakefile to link nxaccess library. + +nx-X11-3.0.0-6 + +- Added the path of nxaccess library to the server link command. + +nx-X11-3.0.0-5 + +- Implemented FR10C01079 and FR10C01080. The merge of NX changes to + the X.org code is complete. + +- Merged changes in config/cf. The NX-*.def files have been dismissed. + Main platform dependent configurations have been moved to host.def. + +- Removed *.reference files from config/cf. + +- Fixed compilation for Cygwin platform. + +nx-X11-3.0.0-4 + +- Imported all changes up to nx-X11-2.0.0-32. + +- Cleaned up lib/zlib directory. + +- Added missing file programs/Xserver/os/utils.c.NX.original. + +- Updated the copyright notice to year 2006. + +- The pointer to the display buffer is reset after an I/O error. + This prevents leaving the buffer in an inconsistent state if the + error occurs inside _XFlush(). + +- Removed the modifications to the Xrender library. The cleanup of + the padding bytes is now performed by the NX transport. + +- NX uses the updated ZLIB from its build tree, so Imake.tmpl will + now assume that the platform as ZLIB unless otherwise stated. + +- The path of the SecurityPolicy file is searched and validated at + runtime. + +- Added the _X11TransSocketProxyConnInfo() function to Xtranssock.c + It returns the pointer to the XtransConnInfo private, if it is a + valid _NXProxyConnInfo structure. + +- The above function is used by OpenDis.c to detect if the NX trans- + port was requested on the display and avoid spurious error messa- + ges in the case of a connection failure. + +- Added NXmiwindow.o to the NXAGENTOBJS in the Xserver's Imakefile + and imported NXmiwindow.c in nxagent. This allows us to check the + pointer to the pOldClip region in miSetShape() before going on + freeing it. + +- The path of the XKB base directory and of the xkbcomp comand is + validated at runtime. + +- Also added a check to verify the validity of the rgb file path. + +- Added NXresource.o to NXAGENTOBJS in the Imakefile of nxagent. We + need this to a assign a resource to the pixmaps and other server + objects which need to be enumerated at reconnection. Some objects, + being created by the X server and not by the clients, don't pass + through the resource assignment process operated by the dix. To + ensure that all objects get a resource, we add a resource at the + time the object is created and temporarily assign the resource to + the server client. If the dix later assigns the resource to a va- + lid client, the resource is removed from the server client's list. + +- The display block handler registered by the client is called in + WaitForReadable() and WaitForWritable() before every select(), + not only upon entering the function. The reason is that more + data can be possibly produced for the NX link by the proxy it- + self and, when setting the flush policy to deferred, the client + may not have the chance of flushing the NX link. + +- Fixed a bug in XkbUseExtension() that caused Xlib to query the + presence of the XKEYBOARD extension multiple times. This partial- + ly implents the FR01D01275. The complete implementation required + modifications to the X11 agent, implemented in nxagent-2.0.0-33. + +- Updated to comply with the new NXTransFlush() interface. + +- Both nxwin and nxagent now read the X authority file by using an + fopen() instead of the system command 'cat'. + +- Removed NXmiwindow.o from the NXAGENTOBJ list. The agent will now + use the original miwindow.c. + +- Added some additional logs in Xtranssock.c to follow the creation + and removal of the X server's Unix listener. + +- Avoided the sleep of 5 seconds forced by Xtransutil.c if the dir- + ectory where the Unix listener is created is not owned by root. + This sleep is not executed on Cygwin (where the X socket can be + hardly owned by root) but may delay the startup of the agent if + the user chose a different NX_TEMP directory. Furthermore, it is + unclear what real benefits such sleeps are intended to bring to + the security of the X server. This can be controlled by defining + the NX_TRANS_SLEEP directive in Xserver/os/Imakefile. + +- Added NXmiexpose.o to the NXAGENTOBJ. + +- Ensured that _X11TransSocketCloseConnInfo() now initiates the NX + shutdown by calling NXTransClose(). + +- Corrected a misplaced #else that made SocketUNIXConnect() skip a + block if the connection was not to the NX transport. + +- Updated to comply with the new NX function prototypes introduced + in nxcomp-2.0.0-31. + +- Moved the most important Xtranssock.c modifications into separate + functions. + +- Ensured that the modifications enabling the internal connections + to the proxy are compiled only when the TRANS_CLIENT directive is + defined. + +- Solved a bug that prevented the X11 socket to be deleted at the X + server shutdown. This needs further tests. + +- Added nxcompext to the link of nxagent, now that the dependency + of libX11 from nxcompext is removed. + +- Improved the Xtranssock routines to never loop through the array + of connection info. + +- Added a congestion flag to the connection info structure and a + function querying the transport and reporting if a change in the + congestion state has occurred. The code is currently not enabled, + because instead of polling the transport, we let the proxy notify + the changes in congestion state by using the callback. The code + can be used in future to extend the library, for example, by add- + ing some counters tracking the bandwidth usage of the socket con- + nection, so that we can make the congestion notifications work + even with a plain X11 connection. + +- Profiled the routines in XlibInt.c to reduce the number of calls + to the error predicate function provided by the client. + +- Fixed the nxcompext build problem that caused make World to fail. + +- Added a 'CONF' target to the X11 and Xext Imakefiles so that the + configure script is not run if the config.status exists. + +- Added the _NXDisplayBlockHandler hook. The function is called by + Xlib before blocking. The parameter says if Xlib is going to wait + for more input or because it needs to write to the display socket. + The client can use the hook to perform any internal operation that + may require some time to complete. The user, though, should not + try to read or write to the display inside the callback routine. + +- Removed the outdated NX_TRANS_PROCESS, NX_TRANS_THREAD and NX_TR- + ANS_INCLUDE defines. + +- Reverted the lib/Xext Imakefile to the original XF86 version and + moved the build of the nxcompext library among the libX11 depend- + encies. + +- Corrected the lib/X11 Imakefile so that a new build of nxcomp and + nxcompext is not attempted if the libraries are up-to-date. + +- Removed the unused display buffer and image cleanup functions. + +- Reverted the PutImage.c file to the original XF86 version. + +- Added the _NXDisplayErrorPredicate function in XlibInt.c. It is + actually a pointer to a function called whenever Xlib is going to + perform a network operation. If the function returns true, the + call will be aborted and Xlib will return the control to the ap- + plication. It is up to the application to set the XlibDisplayIO- + Error flag after the _NXDisplayErrorPredicate returns true. The + function can be used to activate additional checks, besides the + normal failures detected by Xlib on the display socket. For exam- + ple, the application can set the funciton to verify if an inter- + rupt was received or if any other event occurred mandating the + end of the session. + +- Modified XIfEvent(), XMaskEvent() and XPeekIfEvent() to check the + _NXDisplayErrorPredicate function and return immediately if the + function returns true. + +- Modified _XWaitForReadable() to never enter the loop if the dis- + play is broken. + +- Corrected a make problem on Windows that caused the nxcomp and + nxcompext libraries to be referred with the wrong name, with the + result that a new configure and make was attempted at each build + attempt. + +- Merged all the changes to os, Xext, xkb, dix. + +- Changed host.def to build only the agent server. + +- Merged the changes to Xtranssock.c + +nx-X11-3.0.0-3 + +- Merged the changes to lib/X11. Restored original PutImage.c and + ClDisplay.c files. + +nx-X11-3.0.0-2 + +- Created a directory named 'reference' to keep files that are chan- + ged during the development of nx-X11 since the 1.5.0-16 to 2.0.0-32 + version. These files will be removed as long as the differences are + merged to the 3.0.0 version. When all differences are merged, this + directory will be removed. + +nx-X11-3.0.0-1 + +- Opened the 3.0.0 branch based on the nx-X11-2.0.0-9. The 3.0.0 + branch will now support the migration toward the X.org tree. Due + to time concerns, the 2.0.0 branch is going to be based on the + same nx-X11 as the 1.5.0. + +nx-X11-2.0.0-9 + +- Modified the agent link arguments to explicitly include the NX + libraries. + +- Disabled the Xinerama extension to avoid further clashes with + the redefinition of GC in Xlib. + +- Added os/libos.a at the end of the agent link. + +nx-X11-2.0.0-8 + +- Moved the declarations of _NXEnable* and related structures from + Xlibint.h to NXlibint.h. + +- Added provision for building the agent. This can be controlled by + setting NXAgentServer to YES in host.def. + +- Setting the NXUpgradeAgentServer variable to YES in the host.def + file will make the agent assume that it is being built in the new + environment. This variable is normally unset when building in the + 1.5.0 tree. + +nx-X11-2.0.0-7 + +- Fixed a problem on AMD64 due to the size of the area pointed by + the argument of _X11TransBytesReadable(). BytesReadable_t is long, + at least on Linux, while the ioctl() requires a pointer to an int. + The original _X11TransBytesReadable() function simply calls the + ioctl() by passing the pointer that is provided. NXTransReadable(), + instead, was correctly returning the value assuming a pointer to + a long, but this crashes some applications, among them xterm. Now + NXTransReadable() follows the same schema of the ioctl() call and + stores the result assuming a pointer to an int. + +- Removed the outdated NX_TRANS_PROCESS and NX_TRANS_THREAD code. + +nx-X11-2.0.0-6 + +- Made xterm work with the NX transport. This required small changes + to the Xt toolkit's and the xterm's files to let them use the NX + aware select(). This is useful to test the NX transport until the + nxagent server is integrated. + +- When the transport is gone _X11TransSocketBytesReadable() returns + EPIPE. This makes the client become aware of the closure of the + connection. + +- Added a call to NXTransDestroy() in XCloseDisplay(). + +- The exit() function in XlibInt.c causes a call to NXTransExit(). + +- Merged changes to dix/pixmap.c, xkb/xkbDflts.h, mi/Imakefile. + +- Removed unneeded changes and files containing patches already in + the latest X.org distribution: dix/dispatch.c, fb/fbcompose.c, fb/ + fbgc.c, xkb/ddxList.c, font/fontfile/dirfile.c, font/fontfile/ + encparse.c, font/fontfile/fontfile.c, font/FreeType/fttools.c, + Xrender/FillRect.c, Xrender/Picture.c. + +nx-X11-2.0.0-5 + +- Changes to the lib/X11/Imakefile to cleanly build the tree. This + is obtained by creating a link to the Xcomp library in exports/lib + without having to modify the programs' Imakefiles. + +- Finished merging the NX changes in the lib/X11 files. + +- Merged the CHANGELOG with the one from the 1.5.0 tree. + +nx-X11-2.0.0-4 + +- Merged the NX changes in most Xtrans and lib/X11 files. + +nx-X11-2.0.0-3 + +- Temporarily disabled the use of the MMX extensions in the Xserver's + fb code to successfully compile with GCC 4. + +nx-X11-2.0.0-2 + +- Imported the *.NX.reference and *.XF86.reference files that will + be needed for the merge. These files are the *.original from the + 1.5.0 tree. They will be removed as long as the merge advances. + +nx-X11-2.0.0-1 + +- Created the 2.0.0 branch based on X.org the 6.8.99.16 snapshot. + +nx-X11-1.5.0-16 + +- Added the missing *.XF86.original and *.NX.original files. + +nx-X11-1.5.0-15 + +- Made the nxagent server use select() instead of poll() on Solaris + so that it can leverage the new NX transport. + +- Moved the NXTransFlush() call to _XReply(). + +nx-X11-1.5.0-14 + +- Added the 'synchronous' parameter in the _XWaitForReadable() call + to NXTransFlush(). + +nx-X11-1.5.0-13 + +- Removed the log entry in XlibInt.c on calling the NXTransFlush(). + +nx-X11-1.5.0-12 + +- Changed XlibInt.c and utils.c to call NXTransExit(). + +nx-X11-1.5.0-11 + +- Changed XlibInt.c to comply with the new NXTransFlush() interfa- + ce introduced in nxcomp-1.5.0-42. + +- Cosmetic changes to messages printed for debug. + +nx-X11-1.5.0-10 + +- Ensured that all calls to _XIOError() are followed by a return. + +- Put exiting the client program in the case of an I/O error under + the control of the _NXContinueOnDisplayError flag. If set, the + I/O error routine will simply return, leaving to the application + the responsibility of checking the state of the XlibDisplayIOEr- + ror flag. + +- Added some checks whenever a read or write is performed on the X + connection, so that we can exit the I/O loop if the X channel is + gone. It is likely that more work will be needed when trying to + support XTHREADS enabled connections. This should not be a pro- + blem for now, as the default is still to quit the application un- + less the _NXContinueOnDisplayError flag is explicitly set. + +nx-X11-1.5.0-9 + +- Removed the references to the cygipc library in NXWin. Now use the + cygserver daemon to provide the MIT-SHM extension. + +- Fixed an error in the UseCygIPC definition. + +- Changed the cygwin.cf file to avoid redefinition of the BuildGlxExt, + XWinServer and BuildGlxExt symbols. + +nx-X11-1.5.0-8 + +- Added provision for deferred writes in the NX transport. When en- + tering _XWaitForReadable() we must ensure that data is flushed to + the proxy link. + +- Added the UseCygIPC define to NX-Cygwin.def. + +- Updated the NoMachine copyright notice on the modified files. + +nx-X11-1.5.0-7 + +- Added the GLX extension in NX-Sun.def. + +- Added some more logs in WaitFor.c. + +nx-X11-1.5.0-6 + +- Modified Xlibint.h and XlibInt.c to remove the _NXFlushSize para- + meter. New agents run the NX transport in-process, so we don't get + any benefit from increasing the display buffer size. + +- Modified NX-Darwin.def to not build the NXDarwin server. Since the + 1.4.0 version the NXDarwin server is unsupported and the NX client + for the Mac requires that the Apple X server is installed. + +- Changed NX-Linux.def to avoid the warning due to "SharedLibGLw" + being not defined. + +nx-X11-1.5.0-5 + +- Modified the Xserver Imakefile to link nxagent with FbPostFbLibs + and avoid including mfb/libmfb.a. + +- Added the GLX extension in NX-Linux.def. This provides unaccelera- + ted support in nxagent, with GLX operations translated into core X + protocol primitives. + +- Fixed x-X11/programs/Xserver/GL/dri/Imakefile to look in ../../hw/ + /xfree86/os-support/bus for includes. + +nx-X11-1.5.0-4 + +- Avoid calling NXTransSelect() if the transport is gone, so that we + don't have to wait until the timeout. + +- Added the "-fno-strict-aliasing" option to linux.cf when compiling + with a GCC version >= 4. In the words of Stefan Dirsch: "The opt- + ion, which is default since gcc 3.1, can result in wrong code when + the gcc warnings related to it are ignored. And as there are seve- + ral warnings in X11 related to it, it has been disabled for X11 + from the beginning. This didn't change for gcc4, so it still needs + to be used." + +- Added more logs in XlibInt.c and utils.c. A warning is printed if + the SmartScheduler is initialized. + +nx-X11-1.5.0-3 + +- Started integration of nxcomp with the X libraries. The Xtrans + code creates an internal connection to the nxcomp library instead + of a child proxy process. + +- Changed Xpoll.h and XlibInt.c to replace the standard Select + with a version giving NX a chance to check its own descriptors. + +- Implemented the NXTransReadVector() and the NXTransWriteVector() + functions to replace READV() and WRITEV(). + +- Implemented memory-to-memory communication with the NX proxy by + making use of the NXTransAgent() interface. + +nx-X11-1.5.0-2 + +- We think that the way LoadAuthorization() is working is wrong. + It doesn't reset the list of stored authorizations before reading + the new cookies. Our take is that if a new auth file is to be + read, the only cookies that are to be accepted are those that are + in the new file, not those in the file -plus- those that have + been in the file in the past. Furthermore, if the list can't be + read or it is empty, it should assume that it ignores which co- + okies are valid and thus it should disable any access. Your mile- + age can vary. A less draconian approach could be to leave the old + cookies if the file can't be read and remove them only if the + file is empty. + + Adding the cookies without removing the old values for the same + protocol has an important implication. If an user shares the co- + okie with somebody and later wants to revoke the access to the + display, changing the cookie will not work. This is especially + important with NX. For security reasons, after reconnecting the + session to a different display, it is advisable to generate a + new set of cookies, but doing that it is useless with the current + code, as the old cookies are going to be still accepted. On the + same topic, consider that once an user has got access to the X + server, he/she can freely enable host authentication from any + host, so the safe behaviour should be to reset the host based + authenthication at least at reconnection, and keep as valid only + the cookies that are actually in the file. This behaviour would + surely break many applications, among them a SSH connection run + inside a NX session, as ssh -X reads the cookie for the display + only at session startup and does not read the cookies again + when the auth file is changed. + + Another bug (or feature, depending on how you want to consider + it) is that if the authority file contains entries for different + displays (as it is the norm when the authority file is the default + .Xauthority in the user's home), the X server will match -any- of + the cookies, even cookies that are not for its own display. This + means that you have to be careful when passing an authority file + to nxagent and maybe keep separate files for letting nxagent find + the cookie to be used to connect to the remote display and for + letting it find what cookies to accept. If the file is the same, + clients will be able to connect to nxagent with both the cookies. + This bug obviously affects any X server, also the real X server + running on the workstation, so it is common to see nxagent being + able to connect to the X server even if no cookie matches the + real display. + +- Added a check in lib/Xau/AuRead.c to prevent the fread() call to + be interrupted by SIGCHLD while reading the auth file. Due to the + way the old code worked, this could lead to the server enabling + local host access to the display. This problem had been identified + in the past. We just found that all the code dealing with reading + the auth file was affected. The code calls sigprocmask() to block + the signal (though it leaves some other calls unprotected) but the + SIGCHLD was not included in the set. + +- Added SIGCHLD to the set of signals that are blocked when reading + the authorization file. + +- As I was at it, I changed the path to the SecurityPolicy file. A + few Linux ditributors ship the file in $LIBDIR/xserver, a few only + in /etc/X11/xserver, most others in both places. It seems that + those who ship in $LIBDIR/xserver do also in /etc/X11 but the op- + posite is not true, so I switched to /etc/X11. + +nx-X11-1.5.0-1 + +- Opened the 1.5.0 branch. + +nx-X11-1.4.1-2 + +- Set parameter UseCygIPC on cygwin conf file in order to force the + build of MIT-SHM estension. + +- Removed some spurius object file. + +nx-X11-1.4.1-1 + +- Opened the 1.4.1 branch. + +nx-X11-1.4.0-8 + +- Changed DefaultFontPath and DefaultRGBDatabase in + NX-Cygwin.def. + +nx-X11-1.4.0-7 + +- Imported dispatch in nxdarwin package, in order to let + nxdarwin being able to detect new client connection. + +- Changed the Xpm Imakefile to make also .a static library + on Solaris. To link nxviewer and nxdestkop staticaly. + +nx-X11-1.4.0-6 + +- XInput extension enabled on MacOSX. + +- Added some missing backup files of the original XFree86 + package. + +nx-X11-1.4.0-5 + +- Changed the mi Imakefile in order to let xfree86 servers use + the normal mi extension initialization for the XInput exten- + sion. + +- XInput extension enabled on Solaris. + +nx-X11-1.4.0-4 + +- Removed the RejectWellKnownSocket for the cygwin and + MacOSX environments that doesn't use the Xtransport library. + +nx-X11-1.4.0-3 + +- Changed the implementation of the reject method in the + Xtransport library, now close any new incoming connection + immediately without reading or writing to it. + +nx-X11-1.4.0-2 + +- Implemented a reject method in the Xtransport library, + this function accept and close every connection attempt, + on the specified listening socket. + +- Added the new function RejectWellKnownSocket to the os + connection code. + This function use the new transport reject function on + all listening socket. + +nx-X11-1.4.0-1 + +- Opened the 1.4.0 branch. + +- Removed forgotten nxagent-1.3.2-20 directory. + +nx-X11-1.3.2-9 + +- Prevents NX Darwin server going through the reset. On Darwin + we found that the it is not possible to get the correct key- + board layout unless it is set on the local machine, before + the NX session is started, by using xmodmap. As we set the + keyboard locally, we must prevent the X server to reset, or + we would loose any local configuration. + +nx-X11-1.3.2-8 + +- Removed action associated to keysym XK_Terminate_Server. This + could cause agent to be terminated when pressing shift + back- + space if using the default US keyboard mapping. + +- Disabled the remaining debug logs in lib/X11/PutImage.c + +nx-X11-1.3.2-7 + +- Fixed the wrong programs/Xserver/Imakefile in 1.3.2-6 package. + +nx-X11-1.3.2-6 + +- Changed the define from NX_CLEAN_IN_PLACE to NX_CLEAN_INPLACE. + Definition of symbol is now placed in the Imakefile. + +- The new _NXEnableCleanInplace Xlib variable does control which + algorithm is used to clean the images. Setting NX_IMAGEINPLACE + in the environment will activate the in-place cleanup. + +- The default value of _NXEnableCleanInplace is -1. Leaving it to + a value <= 0 disables use of CleanInplace. + +nx-X11-1.3.2-5 + +- Patch in config/cf/sun.cf. Fix for libfontconfig compilation + during gmake Everything on Solaris. + +- Patch in lib/X11/Imakefile. Fix for nxcomp compilation during + gmake World on Solaris. + +nx-X11-1.3.2-4 + +- Image cleanup is now performed by using NXCleanInPlaceImage from + nxcompext. This function saves a buffer copy by cleaning the + padding bytes in the same buffer provided by the caller. Note that + to prevent memory violations in the case the image was allocated + in a static buffer, the function will temporarily redefine the + SIGSEGV handler. The former handler is restored before returning + to the caller. This can potentially affect some multithreaded + clients. Is to be decided if the function is safe enough to be + included in the production release. + +nx-X11-1.3.2-3 + +- More debug logs in programs/Xserver/xkb/ddxLoad.c. + +nx-X11-1.3.2-2 + +- Added NXmiwindow.o to NXAGENTOBJS in programs/Xserver/Imakefile. + File was not linked into the resulting nxagent. This solves the + problem of missing repaints in CDE and other Xt applications. + +nx-X11-1.3.2-1 + +- Added some debug logs in programs/Xserver/xkb/ddxLoad.c. Function + XkbDDXCompileKeymapByNames is called by OpenOffice to read the + keyboard configuration whenever a drop-down menu is accessed. It + seem to always fail with the following error: + + The XKEYBOARD keymap compiler (xkbcomp) reports: + > Error: Can't find file "unknown" for geometry include + > Exiting + > Abandoning geometry file "default" + +- Opened the 1.3.2 development branch. + +nx-X11-1.3.1-12 + +- Fixed a problem in xkb/ddxLoad.c on Solaris where Pclose was + always returning an error code despite the fact that command + was executed properly. + +nx-X11-1.3.1-11 + +- Changed default GCC flags from '-O2 -fno-strength-reduce' to + -O3. No platform where NX is targeted is currently using a + GCC 2.x affected by the -fno-strength-reduce bug. Note also + that nxcomp is already compiled with -O3 since 1.1.1, so it + can be considered safe. + +nx-X11-1.3.1-10 + +- Imported an updated fbcompose.c file from XFree86-4.3.99.902. + This fixes "uninitialized value" problems reported by Valgrind. + +- Fixed further buffer overflows by updating the following file + with recent versions coming from the XFree86-4.3.99.902 tree. + + nx-X11/lib/font/fontfile/dirfile.c + nx-X11/lib/font/fontfile/encparse.c + nx-X11/lib/font/fontfile/fontfile.c + +- Fixed a possible buffer overflow in lib/font/FreeType/fttools.c. + Verified that the change is already in the XFree86 4.4.0 CVS. + +nx-X11-1.3.1-9 + +- Fixed Xserver/Imakefile which was still referencing NXpixmap.o. + +nx-X11-1.3.1-8 + +- Imported an updated fbgc.c from XFree86-4.3.99.902. This fixes + some minor problems reported by Valgrind. + +- A major problem was reported by Valgrind about reading after + the block allocated in fbCreatePixmap from AllocatePixmap. The + file pixmap.c has been modified so that 4 bytes are added to + the pixmap buffer at any new allocation. This quick hack should + solve the problem for both nxagent and the NXWin server. Further + investigation is planned for the next release. + +- Fixed Xtranssock.c to compile on Solaris where struct sigaction + doesn't have the sa_restorer member. + +nx-X11-1.3.1-5 + +- Renamed the NX-sun.def configuration file to NX-Sun.def. + +- Renamed the non-standard NX_iPAQ_XServer and NX_Zaurus_XServer + symbols to NXiPAQXServer and NXZaurusXServer. + +- Added the missing sun.cf.XF86.original file in config/cf. + +- Added the missing empty file host.def.XF86.original in the + same directory. + +- Added initialization of sa.sa_mask when setting sigaction() + for SIGCHLD. The problem was reported by Valgrind running + nxagent. + +- Removed an unused block of code from WaitFor.c. The code had + been commented out in previous versions. + +- Removed the non-standard colon at the end of version in this + CHANGELOG. + +- Removed the spurious spaces in this CHANGELOG. + +nx-X11-1.3.1-4 + +- Added a little workaround to the top Imakefile intended to + hide the makedepend warnings about non portable whitespaces + in sources. + +nx-X11-1.3.1-3 + +- Fixed compilation problem with nxagent-1.3.1-13. + +nx-X11-1.3.1-2 + +- Changes in NX-sun.def configuration file for Solaris to allow + compilation of the XKB extension. + +nx-X11-1.3.1-1 + +- Opened the 1.3.1 development branch. + +nx-X11-1.3.0-6 + +- 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 but agents should set it to 0 if they + want to disable early flush. + +- Added the _NXLostSequenceFunction function pointer to let NX + agents suppress the error message and modify the default Xlib + behaviour when out-of-order sequence numbers are received. |
