2011-02-24record: avoid crash when calling RecordFlushReplyBuffer recursivelyErkki Seppälä1-1/+5
RecordFlushReplyBuffer can call itself recursively through WriteClient->CallCallbacks->_CallCallbacks->RecordFlushAllContexts when the recording client's buffer cannot be completely emptied in one WriteClient. When a such a recursion occurs, it will not be broken out of which results in segmentation fault when the stack is exhausted. This patch adds a counter (a flag, really) that guards against this situation, to break out of the recursion. One alternative to this change would be to change _CallCallbacks to check the corresponding counter before the callback loop, but that might affect existing behavior, which may be relied upon.

2010-06-22record: Prevent a crash on recording client disconnect.Rami Ylimäki1-5/+17
Execute the following steps to reproduce the issue. 1. Run at least two recording clients simultaneously. $ cnee --record --request-range 1-127 & $ cnee --record --request-range 1-127 & 2. Kill the recording clients. $ killall cnee 3. Give X server something to do so that the clients are closed. $ xinput list $ xinput list As a result RecordUninstallHooks accesses NullClient, because RecordAClientStateChange doesn't clean the recording clients up properly. Fix RecordUninstallHooks to fail locally on an assertion instead of much later in privates code, if NullClient is still accessed because of some other bug. Fix RecordAClientStateChange to iterate through all contexts so that modifications of the iterated array during iteration don't cause contexts to be skipped.

2010-06-03Move each screen's x/y origin into ScreenRec.Jamey Sharp1-4/+5
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.

Looks like Xproto.h dropped them by X11R6.3, which didn't have the #ifdef's anymore, so these are truly ancient now."
