2011-05-04composite: Call ValidateGC after ChangeGCVille Syrjälä1-2/+1
ChangeGC changes the GC, so ValidateGC should be called after it, not before. Also pass NullClient instead of serverClient to ChangeGC() since we know the changed values to be valid, and setting serverClient->errorValue seems pointless anyway.

2011-01-05composite: Support updating an arbitrary subtreeVille Syrjälä4-13/+31
Rename compUpdateWindow to compPaintWindowToParent and split the child walk to compPaintChildrenToWindow. Calling compPaintChildrenToWindow allows an arbitrary subtree to be updated, instead of having to update all the windows. This will be used to make sure all the descendants are copied to the parent when the parent window contents need to be accessed in IncludeInferios sub-window mode. WindowRec has a new member 'damagedDescendants' that is used to keep track of which subtrees need updating. When a window is damaged, 'damagedDescendants' will be set for all the ancestors, and when a subtree is updated, the tree walk can be stopped early if no damaged descendants are present. CompScreenRec no longer needs the 'damaged' member since the root window's 'damagedDescendants' provides the same information.

2011-01-05Revert "composite: Convert compWindowUpdate to use TraverseTree"Ville Syrjälä1-15/+15
TraverseTree visits the parent before the children. When performing the automatic redirection updates, the children must be visited before the parent. If there are automatically redirected windows on multiple levels of the tree, updating the parents before the children would cause the parent updates to use stale data for areas covered by the children. Also updating the damaged children would re-damage the parent, which would cause additional walks over the tree. In the worst case with an unbroken chain of automatically redirected subwindows, all of which are damaged, only the leaf window would be properly updated on the first round. Then it's parent would be properly updated on the second round, and so on. And on every round all of the ancestor windows would be updated as well, but with stale data. So with N damaged windows you would end up with (N^2+N)/2 updates, instead of the expected N. This reverts commit 648c8871c92727d7b6b16859f27f12266a06a16e.

2010-06-22composite: fix freeing of old pixmap until after move/resize/cbw (bug 28345)Dave Airlie3-10/+87
The fixes for the composite reallocation failure, were freeing the oldpixmap straight after reallocating the new one, however this led to some wierd effects in e16 compositing, and I think in a few other places. This patch moves the freeing of the pixmap into the post wrapped stage. I'm not sure if we are actually better off breaking ABI and adding another callback from the ConfigureWindow to composite to make sure the old pixmap is always freed, but this should be satisfactory as we should always hit one of the freeing paths or else its a bug in the DIX. bug: https://bugs.freedesktop.org/show_bug.cgi?id=28435 Reported-by: Andrew Randrianasulu <randrik@mail.ru> Signed-off-by: Dave Airlie <airlied@redhat.com> Reviewed-by: Keith Packard <keithp@keithp.com> Signed-off-by: Keith Packard <keithp@keithp.com>

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.

2010-06-03composite: use config notify hook to do pixmap resize.Dave Airlie3-153/+54
Since reallocating the backing pixmap can fail, we need to try and do it before any other side effects of reconfiguring the window happen. This changes the ConfigNotify hook to return status, and moves the composite window reconfiguration wrappers to ConfigNotify. They all basically did the same thing, so we can drop the MoveWindow, ResizeWindow, ChangeBorderWidth wrappers, and allow ConfigNotify to do all the work. If reallocation fails we fail before we send any confiureNotify events, or enter the area we can't recover from. The only place we now enforce 32k limits are in EXA/UXA/fb, so drivers that don't use this should probably deal with it in their pixmap allocate if they don't already. This also breaks ABI, so we need an alternate fix for older servers, working on the X server makes me realise why I'm a kernel hacker.

Many references to the WindowTable array already had the corresponding screen pointer handy, which meant they usually looked like "WindowTable[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.

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.

Save in a few special cases, _X_EXPORT should not be used in C source files. Instead, it should be used in headers, and the proper C source include that header. Some special cases are symbols that need to be shared between modules, but not expected to be used by external drivers, and symbols that are accessible via LoaderSymbol/dlopen. This patch also adds conditionally some new sdk header files, depending on extensions enabled. These files were added to match pattern for other extensions/modules, that is, have the headers "deciding" symbol visibility in the sdk. These headers are: o Xext/panoramiXsrv.h, Xext/panoramiX.h o fbpict.h (unconditionally) o vidmodeproc.h o mioverlay.h (unconditionally, used only by xaa) o xfixes.h (unconditionally, symbols required by dri2) LoaderSymbol and similar functions now don't have different prototypes, in loaderProcs.h and xf86Module.h, so that both headers can be included, without the need of defining IN_LOADER. xf86NewInputDevice() device prototype readded to xf86Xinput.h, but not exported (and with a comment about it).
