2017-01-11AttendClient of grab-pervious client must queue to saved_ready_clients [v2]Keith Packard1-0/+10
A client which is attended while a grab is blocking execution of its requests needs to be placed in the saved_ready_clients list so that it will get scheduled once the grab terminates. Otherwise, if the client never sends another request, there is no way for it to be placed in the ready_clients list. v2: Wrap comment above mark_client_saved_ready. Remove test for OS_COMM_IGNORED which will always be true.

2017-01-02os,dix: Depend custom libs on libs, not objectsMihail Konev1-2/+2
The custom os/os.O library reuses *.o files of os/libos.la. The current rule assumes automake puts all the objects into per-target am__*_la_OBJECTS variable. At least with AC_REPLACE_FUNCS, this no longer holds (as wanted objects are put into LTLIBOBJS instead). Depend on automake's result, the *.la library instead, to express demand of any its dependencies being built. Should be fixing randomly occuring "undefined reference to `strlcpy'" errors when linking Xvfb and other DDX-es that could use os.O.

2016-11-29xwayland: Don't send KeyRelease events on wl_keyboard::leaveRui Matos1-1/+4
Commits 816015648ffe660ddaa0f7d4d192e555b723c372 and fee0827a9a695600765f3d04376fc9babe497401 made it so that wl_keyboard::enter doesn't result in X clients getting KeyPress events while still updating our internal xkb state to be in sync with the host compositor. wl_keyboard::leave needs to be handled in the same way as its semantics from an X client POV should be the same as an X grab getting triggered, i.e. X clients shouldn't get KeyRelease events for keys that are still down at that point. This patch uses LeaveNotify for these events on wl_keyboard::leave and changes the current use of KeymapNotify to EnterNotify instead just to keep some symmetry between both cases. On ProcessDeviceEvent() we still need to deactivate X grabs if needed for KeyReleases.

2016-11-15dix: Make sure client is not in output_pending chain after closed (RH 1382444)Keith Packard1-1/+1
I think it is possible that output could get queued to a client during CloseDownClient. After it is removed from the pending queue, active grabs are released, the client is awoken if sleeping and any work queue entries related to the client are processed. To fix this, move the call removing it from the output_pending chain until after clientGone has been set and then check clientGone in output_pending_mark.

Some games incorrectly use non-premultiplied ARGB cursor data, presumably because that's what Windows uses. On some hardware (and with SWcursor), this breaks areas of the cursor which are supposed to be transparent (and presumably also translucent areas, but that's less noticeable). This change checks for pixels with alpha == 0 and any non-alpha component != 0. If any such pixel is found, the data is assumed to be non-premultiplied and fixed up by multiplying the RGB components with the alpha component.

2016-06-20dix: Call screen block/wakeup handlers closest to blocking [v3]Keith Packard1-10/+13
The screen block and wakeup handlers are the only ones which provide a well known ordering between the wrapping layers; placing these as close as possible to the server blocking provides a way for the driver to control the flow of execution correctly. Switch the shadow code to run in the screen block handler so that it now occurrs just before the server goes to sleep. Switch glamor to call down to the driver after it has executed its own block handler piece, in case the driver needs to perform additional flushing work after glamor has called glFlush. These changes ensure that the following modules update the screen in the correct order: animated cursors (uses RegisterBlockAndWakeupHandlers dynamically) composite (dynamic wrapping) misprite (dynamic wrapping) shadow (static wrapping) glamor (static wrapping) driver (static wrapping) It looks like there's still a bit of confusion between composite and misprite; if composite updates after misprite, then it's possible you'd exit the block handler chain with the cursor left hidden. To fix that, misprite should be wrapping during ScreenInit time and not unwrapping. And composite might as well join in that fun, just to make things consistent. [v2] Unwrap BlockHandler in shadowCloseScreen (ajax) [v3] ephyr: Use screen block handler for flushing changes ephyr needs to make sure it calls glXSwapBuffers after glamor finishes its rendering. As the screen block handler is now called last, we have to use that instead of a registered block/wakeup handler to make sure the GL rendering is done before we copy it to the front buffer.

2016-06-17xrandrprovider: Do not use separate lists for unbound / source / offload slavesHans de Goede1-13/+17
A single provider can be both a offload and source slave at the same time, the use of seperate lists breaks in this case e.g. : xrandr --listproviders Providers: number : 2 Provider 0: id: 0x7b cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 2 associated providers: 0 name:modesetting Provider 1: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 5 associated providers: 0 name:modesetting xrandr --setprovideroutputsource 1 0x7b xrandr --listproviders Providers: number : 2 Provider 0: id: 0x7b cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 2 associated providers: 1 name:modesetting Provider 1: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 5 associated providers: 1 name:modesetting xrandr --setprovideroffloadsink 1 0x7b xrandr --listproviders Providers: number : 3 Provider 0: id: 0x7b cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 2 associated providers: 2 name:modesetting Provider 1: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 5 associated providers: 2 name:modesetting Provider 2: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 5 associated providers: 2 name:modesetting Not good. The problem is that the provider with id 0x46 now is on both the output_slave_list and the offload_slave_list of the master screen. This commit fixes this by unifying all 3 lists into a single slaves list. Note that this does change the struct _Screen definition, so this is an ABI break. I do not expect any of the drivers to actually use the removed / changed fields so a recompile should suffice.

There are no in-tree consumers of the audit hooks, and they are in any case redundant with the dtrace dispatch hooks. Neither is there any in-tree user of the core request dispatch hook.

2016-06-01dix: Don't update current time in the middle of input event processingKeith Packard2-2/+0
In patch 137ac094e7ab8c871f3b36e40ad826ac797f0e26, Adam moved an expensive call to UpdateCurrentTime out of the main dispatch loop. That's a good change as the original fix from Chase was a bit expensive. However, it breaks grab processing and so a couple of the calls to UpdateCurrenTime need to be removed. Input event processing can generate a stream of events; a button press that activates a grab will send a press followed by a sequence of enter/leave events. All of these should have the same time stamp on the wire as they occur at the 'same' time. More importantly, the grab time recorded in the device is pulled from currentTime after all of the events are delivered, so if currentTime doesn't match the time in the device event, then future grab modifications will fail as the time marked in the device will be 'later' than the grab time known to the client (which is defined as the timestamp from the activating input event). A bit of history here -- it used to be that currentTime was driven *entirely* by input events; those timestamps didn't even have to be related to the system time in any way. Then we started doing ICCCM stuff and people got confused when PropertyNotify events would have the same timestamp even when delivered minutes apart because no input events were delivered. We added code in the server to go update the time, but only if no input events were pending (so that the clock "wouldn't" go backwards). The only places where this is necessary is in request processing which may generate an event with a timestamp, and there only at the very top of the request processing code so that the whole request would be processed at the 'same time', just like events. cc: Chase Douglas <chase.douglas@canonical.com> cc: Peter Hutterer <peter.hutterer@who-t.net> cc: Adam Jackson <ajax@redhat.com> Signed-off-by: Keith Packard <keithp@keithp.com> Tested-by: Michel Dänzer <michel.daenzer@amd.com> Acked-by: Peter Hutterer <peter.hutterer@who-t.net>

2016-02-22dix: Add hybrid full-size/empty-clip mode to SetRootClipDaniel Stone1-11/+21
216bdbc735 removed the SetRootClip call in the XWayland output-hotplug handler when running rootless (e.g. as a part of Weston/Mutter), since the root window has no storage, so generating exposures will result in writes to invalid memory. Unfortunately, preventing the segfault also breaks sprite confinement. SetRootClip updates winSize and borderSize for the root window, which when combined with RRScreenSizeChanged calling ScreenRestructured, generates a new sprite-confinment area to update it to the whole screen. Removing this call results in the window geometry being reported correctly, but winSize/borderSize never changing from their values at startup, i.e. out of sync with the root window geometry / screen information in the connection info / XRandR. This patch introduces a hybrid mode, where we update winSize and borderSize for the root window, enabling sprite confinement to work correctly, but keep the clip emptied so exposures are never generated.
