Jeremy deleted rootlessAccelInit's implementation in 2008 in commit 587c010a1cd733fded4d49dc339df0634bda8be6. Delete its prototype and the remaining commented-out call to it. It still makes sense for the rootless GC ops to relax the planemask, but that's independent of the size of the operation, so quit checking the thresholds there. FillBytes and CompositePixels are not called anywhere, so delete everything related to both.

2010-09-11rootless: Remove ROOTLESS_WORKAROUNDJeremy Huddleston1-5/+1
This was already removed for XWin (20701522be803fe47e921fcf059dadf64c7f287d) with no reported side effects. XQuartz seems to be behaving ok without it as well. While this possibly brings back bug #1168, we don't have any reproduction steps for that issue, and if it crops up again, we should fix it a real way rather than this hokey workaround which doesn't even work for COMPOSITE. This effectively reverts the following two changes: b2135e589baeb2ea26da50b9167feaea23bcce3c d7fef52254126aa5897a5c58faeda1f61d5b13d8 Signed-off-by: Jeremy Huddleston <jeremyhu@apple.com> Reviewed-by: Jon TURNEY <jon.turney@dronecode.org.uk>

2010-08-10rootless: fix uninitialized private key assert in non-rootless modes in Cygwin/XJon TURNEY1-0/+3
IsFramedWindow() is called from miPaintWindow() if the server has been built with ROOTLESS defined, irrespective of if RootlessInit() has ever been called, or not. Add a check to IsFramedWindow() to check if rootlessWindowPrivateKey has been registered (as a proxy for checking if the rootless extension has been initialized) so we don't go on to try to use that key, triggering an assert. This bug exposes what appears to be a difference in opinion about the rootless extension between XQuartz and XWin. XQuartz always initializes the rootless extension, whereas XWin offers several modes of operation, and the rootless extension is only used for one of them That probably means that the all code under compile time guard for ROOTLESS should be carefully checked that it doesn't also need to be under a run-time guard (I've reviewed the other ROOTLESS blocks in dix/events.c and dix/window.c and they look ok -- keithp) Signed-off-by: Jon TURNEY <jon.turney@dronecode.org.uk> Reviewed-by: Keith Packard <keithp@keithp.com> Signed-off-by: Keith Packard <keithp@keithp.com>
2010-07-19rootless: Adjust the frame size of the native root window in ↵Jan Hauffa1-0/+7
RootlessResizeWindow If the native root window isn't resized as well, we will likely crash the next time we draw to the root. On OS X, this can be seen by: 1) Put the display preferences in the menu bar and set X11's preferences so you can access the menu bar in fullscreen mode 2) Set the resolution of your screen lower than normal. 3) Start X11 in fullscreen mode. The root window will cover the screen as expected. 4) Use the menu bar to increase the resolution of the display. The root window will now cover the old area and not the full screen, but 'xwininfo -root' will report the full width. 5) Run 'xsetroot -solid red', and we have the crash you mention above. Leaving/entering fullscreen after #4 will fix the problem. This is because the WINREC is erased when we leave fullscreen mode and it is recreated upon re-entry: RootlessUpdateRooted(FALSE) RootlessDisableRoot(screenInfo.screens[0]) RootlessDestroyFrame (pRoot, winRec); RootlessUpdateRooted(TRUE) RootlessEnableRoot(screenInfo.screens[0]) RootlessEnsureFrame(screenInfo.screens[0]->pRoot) creates a new WINREC...

2010-06-05Rename region macros to eliminate screen argumentKeith Packard13-192/+192
This is a combination of a huge mechanical patch and a few small fixups required to finish the job. They were reviewed separately, but because the server does not build without both pieces, I've merged them together at this time. The mechanical changes were performed by running the included 'fix-region' script over the whole tree: $ git ls-files | grep -v '^fix-' | xargs ./fix-region And then, the white space errors in the resulting patch were fixed using the provided fix-patch-whitespace script. $ sh ./fix-patch-whitespace Thanks to Jamey Sharp for the mighty fine sed-generating sed script. The hand-done changes involve removing functions from dix/region.c that duplicate inline functions in include/regionstr.h, along with their declarations in regionstr.h, mi.h and mispans.h.

2010-06-03Move each screen's x/y origin into ScreenRec.Jamey Sharp1-4/+4
Many references to the dixScreenOrigins array already had the corresponding screen pointer handy, which meant they usually looked like "dixScreenOrigins[pScreen->myNum]". Adding a field to ScreenRec instead of keeping this information in a parallel array simplifies those expressions, and eliminates a MAXSCREENS-sized array. Since dix declared the dixScreenOrigins array, I figure allocating a screen private for these values is overkill.

2010-02-17os: Prevent core dump from being truncated.Rami Ylimaki2-6/+6
The problem fixed by this patch can be reproduced on Linux with the following steps. - Access NULL pointer intentionally in ProcessOtherEvent on key press. - Instead of saving core dump to a file, write it into a pipe. echo "|/usr/sbin/my-core-dumper" > /proc/sys/kernel/core_pattern - Dump the core by pressing a key. While the core is being dumped into the pipe, the smart schedule timer will cause a pending SIGALRM. Linux kernel stops writing data to the pipe when there are pending signals. This causes the core dump to be truncated. On my system I'm expecting a 6 MB dump but the size will be 60 kB instead. The problem is solved if we block the SIGALRM caused by expired smart schedule timer. I haven't been able to reproduce this problem in the following cases. - Save core dump to a file instead of a pipe. - kill -SEGV `pidof Xorg` - Press a key to dump core while gdb is attached to Xorg. - Give option -dumbSched to Xorg. Also note that the fix works only when NoTrapSignals has the default value FALSE. The problem can still be reproduced if error signals aren't trapped. In addition to pending SIGALRM, there is a similar problem with pending SIGIO from the keyboard driver during core dump.
