2010-07-13Unwrap/rewrap EnterVT/LeaveVT completely, Fixes 28998Keith Packard2-4/+30
Because some EnterVT code needs to remove it self from the call chain, we need to fix all of the wrappers to correctly unwrap/rewrap during the call chain. This is a follow-on to the fix for bug 27114 in commit 68a9ee8370e6f9b38218376ac92d5130a5b0ef1e.

2010-06-05Rename region macros to eliminate screen argumentKeith Packard2-9/+9
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.

2010-05-13dri2: Send out event when auxillary buffers are invalidatedKristian Høgsberg1-1/+22
This lets the DRI2 clients rely on the server to notify them when they need to get new buffers. Without this, OpenGL clients poll the server in glViewport() which can be a performance problems and also isn't completely correct behaviour. We bump the DRI2 protocol minor to indicate the availability of the event, which the DRI2 clients can use to avoid polling. This speeds up various piglit and oglc test cases as well as real applications.

2010-05-11dri2: Take an XID for tracking the DRI2 drawableKristian Høgsberg5-21/+34
Some pixmaps (window pixmaps and scratch pixmaps) don't have the drawable->id set and thus DRI2 gets confused when using that field for looking up the DRI2 drawable. Go back to using privates for getting at the DRI2 drawable from a DrawablePtr. We need to keep the resource tracking in place so we can remove the DRI2 drawable when the X resource it was created for goes away. Additionally, we also now track the DRI2 drawable using a client XID so we can reclaim the DRI2 drawable even if the client goes before the drawable and doesn't destroy the DRI2 drawable.

2010-05-11glxdri2: Hard-code the extension version we needKristian Høgsberg1-3/+3
If we use the #define'd version from dri_interface.h, the server will require at least that version of the extension. If we're compiling against a dri_interface.h with a newer version we don't really require, glxdri2 will require a too high version of the extension. The right approach is to just hard-code the version we need instead of using the #defines.

The main motivation here is to have the resource system clean up the DRI2 drawable automatically so glx doesn't have to. Right now, the glx drawable resource must be destroyed before the X drawable, so that calling DRI2DestroyDrawable doesn't crash. By making the DRI2 drawable a resource, GLX doesn't have to worry about that and the resource destruction order becomes irrelevant. https://bugs.freedesktop.org/show_bug.cgi?id=26394 Signed-off-by: Kristian Høgsberg <krh@bitplanet.net> Signed-off-by: Keith Packard <keithp@keithp.com>

GLX pbuffers are implemented using a pixmap allocated by the server. With the change to DRI2 to track DRI2 drawables as resources, we need to make sure that every drawable we create a DRI2 drawable for has an XID. By using the XID of the pbuffer, the resource system will automatically reclaim the hidden pixmap and the DRI2 drawable when the pbuffer is destroyed or the client exits.

2010-02-17os: Prevent core dump from being truncated.Rami Ylimaki1-1/+1
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.
