* xkb: remove oldState from XkbHandleActions.Ulrich Sibiller2019-06-221-4/+2
| | | | | | | | | | | | | | | | | | | | Fixes this cppcheck finding: [nx-X11/programs/Xserver/xkb/xkbActions.c:1306]: (error) Uninitialized variable: oldState commit 35a4b8e7f4526a92d44cb16a783f21030cd1f6df Author: Peter Hutterer <peter.hutterer@who-t.net> Date: Tue May 5 16:51:59 2009 +1000 xkb: remove oldState from XkbHandleActions. I really don't know what the purpose of this variable is or was, aside from potentially clobbering up our key state since there's a path where it may be used uninitialised. Also, this means that xkbi->prev_state is now accessible from the DIX with meaningful data. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

* CloseDevice: call XkbRemoveResourceClient before freeing key class structUlrich Sibiller2019-06-191-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | This patch is not necessary at the current code level. But when xkb code introduced the dev->key check Xorg upstream missed that. So we backport it now to skip that trap when updating xkb code. Author: Alan Coopersmith <alan.coopersmith@sun.com> Date: Mon Jan 4 18:21:54 2010 -0800 CloseDevice: call XkbRemoveResourceClient before freeing key class struct XkbRemoveResourceClient() returns immediately if dev->key is NULL. CloseDevice calls XkbRemoveResourceClient until it removes all resources. If we free dev->key and NULL it before XkbRemoveResourceClient, then infinite loop ensues, and the server appears to hang on exit or crash.

* Screen.c: Fix: make sure RRCloseScreen is being calledUlrich Sibiller2019-06-191-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes ArcticaProject/nx-libs#598 In nxagentOpenScreen we first initialized the RRExtension for the screen and then replaced pScreen->CloseScreen by nxagentCloseScreen. This resulted in RandR's RRCloseScreen (and any other CloseScreen procedure installed by extensions) being no longer called. Moving RandR init after configuring pScreen->CloseScreen ensures the correct calling cascade: RRCloseScreen -> nxagentCloseScreen ->fbCloseScreen (called explicitly by nxagentCloseScreen).

* NXmiexpose.c: use upstream version of miPaintWindows()Ulrich Sibiller2019-06-112-273/+2
| | | | | | | | | miPaintWindow() was identical to the version in miexpose.c except for some unitialized variable fixes. As these also should be in upstream code we add them there (Note: Xorg never fixed this but totally rewrote the miPaintWindow() later on.) This allows us to totally drop our special version of miPaintWindow().
