2011-09-21Use correct swap{l,s} (or none at all for CARD8)Matt Turner1-2/+2
Swapping the wrong size was never caught because swap{l,s} are macros. It's clear in the case of Xext/xres.c, that the author believed client_major/minor to be CARD16 from looking at the code in the first hunk. v2: dmx.c fixes from Keith.

2011-07-29randr: Compare all the bytes in RRPostPendingPropertiesAaron Plattner1-1/+1
RRPostPendingProperties tries to compare the pending and current property values to decide whether they're actually changing. However, it does this using a memcmp that passes in pending_value->size as the number of bytes. This is actually the number of elements, where each element is (pending_value->format / 8) bytes long. This causes the pending value to not be propagated if the first pending_value->size bytes are the same and only the end of it is changing. Fix this by computing the total number of bytes to compare in the memcmp.

2011-05-25randr: check rotated virtual size limits correctlyAaron Plattner1-6/+6
Commit d1107918d4626268803b54033a07405122278e7f introduced checks to the RandR path that cause RRSetScreenConfig requests to fail if the size is too large. Unfortunately, when RandR 1.1 rotation is enabled it compares the rotated screen dimensions to the unrotated limits, which causes 90- and 270-degree rotation to fail unless your screen happens to be square: X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 153 (RANDR) Minor opcode of failed request: 2 (RRSetScreenConfig) Value in failed request: 0x780 Serial number of failed request: 14 Current serial number in output stream: 14 Fix this by moving the check above the code that swaps the dimensions based on the rotation.

Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=30367 Currently the ddx calls xf86RandR12Init() (-> RRScreenInit() -> RRInit() -> RRModeInit() -> RRCrtcInit() -> RROutputInit()) before RRExtensionInit() is called. This causes RRErrorBase being 0 while setting resource type error values (resource types: RROutput, RRMode and RRCrtc).

Commit 77c7a64e8885696665556c9fbcb3cffb552e367a was introduced to fix a cursor off by one on Intel hw, however it also move the whole crtc into an off by one position and you could see gnom-eshell overlapping. This commit reverts that and instead fixes the cursor hotspot translation to work like pixman does. We add 0.5 to the cursor vector before translating, and floor the value afterwards.

2010-06-03Move each screen's root-window pointer into ScreenRec.Jamey Sharp2-6/+6
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. Since dix uses this data, a screen private entry isn't appropriate. xf86-video-dummy currently uses WindowTable, so it needs to be updated to reflect this change.

2010-05-19Make WriteEventsToClient/WriteToClient no-op on fake or dead clients.Jamey Sharp1-6/+1
This matches the test in TryClientEvents, and is a superset of tests done by the callers of these functions. The consequence of forgetting these tests is a server crash, so they're always desirable. In my opinion, it's better to not require the callers to remember to do these checks. For callers that don't do very much work before calling WriteToClient or WriteEventsToClient, I've removed the redundant checks. hw/xquartz/xpr/appledri.c has an interesting case: While its check for "client == NULL" appears redundant with the test in WriteEventsToClient, it dereferences client to get the sequence number.
