* Keyboard.c: nullify freed pointersUlrich Sibiller2019-06-191-7/+11
| | | | | | | While trying to properly free memory allocated by XKB I accidently called nxagentFreeKeyboardDeviceData twice and noticed it would cause a segfault here. As the other pointers are also nullified after being freed let's just do it here, too.
* 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). Which in turn will fix this memory leak: ==9688== 328 (312 direct, 16 indirect) bytes in 1 blocks are definitely lost in loss record 271 of 319 ==9688== at 0x4837B65: calloc (vg_replace_malloc.c:752) ==9688== by 0x4ED2C6: RRScreenInit (randr.c:329) ==9688== by 0x1F2B18: nxagentInitRandRExtension (Extensions.c:122) ==9688== by 0x1DEAFF: nxagentOpenScreen (Screen.c:1409) ==9688== by 0x16D7F8: AddScreen (dispatch.c:4257) ==9688== by 0x1DA0CF: InitOutput (Init.c:397) ==9688== by 0x14DCC2: main (main.c:280)

* Window.c: Drop defines CWParent and CWStackingOrderUlrich Sibiller2019-06-122-17/+14
| | | | | | They were just aliases to already existing defines and were not used stringently. So we had mix of aliased and non-aliased uses which is confusing when trying to understand the code...
* Window.c: remove leftover (commented) codeUlrich Sibiller2019-06-121-14/+0
| | | | | | | | | | | This was eventually replaced by nxagentAddConfiguredWindow(pWin, CW_Map) some lines below which is just leading to the same code being executed some time later. (nxagentAddConfiguredWindow() will add a window to a list. nxagentFlushConfiguredWindow() is called at certain points to update all windows in that list in one go. "update" here means calling XConfigureWindow() or XMapWindow() on the real display.)

| | | | | | | | | | | | | We are not using any alloc function that respects that variable, so lets drop it.

* NXmiexpose.c: use upstream version of miPaintWindows()Ulrich Sibiller2019-06-111-269/+0
| | | | | | | | | 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().
* NXmiexpose.c: use upstream miHandleExposures()Ulrich Sibiller2019-06-111-274/+0

* Fix NXevents.c: Reactivate errornously commented functionUlrich Sibiller2019-06-111-66/+75
| | | | | | | | | CheckMotion() had been commented in add881931f2e702fb1952f4e1baba04b3dc536ee as it looked identical to the version from dix/events.c except for some commented code. But this based (probably) on a thinko - code that had been disabled by NX became active again this way. Fix this by removing the comments and by adding #ifdef/else to emphasize the difference.
