*	3rdparty: Add touchpad gestures support to bundled xinput xcb module	Povilas Kanapickas	2021-11-13	1	-1/+45
\| \| \| \| \| \| \| \| \| \|	This feature can easily be backported to our bundled version of libxcb because the feature is pretty much self-contained (just a couple of new events and parsing support) and does not depend on newer features of libxcb that have appeared since our bundled version of 1.13.

*	3rdparty: Fix forwards-compatibility bug in bundled xinput xcb module	Povilas Kanapickas	2021-09-20	1	-25/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	libxcb thinks that it knows about all device class types sent by the X server XInput extension. With the addition of touchpad gestures in XInput 2.4 and X server 21.1 this is no longer the case and libxcb fails horribly by thinking that the protocol was malformed. The X server currently has a workaround, but it would not address the following situation: - there are multiple modules within the same X client (e.g. part of the application uses Qt, another part talks to X server via another library) - both of the modules talk to XI - at least one module requests for XI 2.4 protocol support. The request for XI 2.4 disables the workaround on the X server and Qt side would crash horribly. This bug is being fixed upstream in these MRs: https://gitlab.freedesktop.org/xorg/proto/xcbproto/-/merge_requests/23 https://gitlab.freedesktop.org/xorg/lib/libxcb/-/merge_requests/20 Change-Id: Idf345271340031152b512ef59f619313be5ec226 Reviewed-by: Allan Sandfeld Jensen <allan.jensen@qt.io> Reviewed-by: Shawn Rutledge <shawn.rutledge@qt.io>
*	3rdparty: remove xcb libs and bump minimal required version to 1.11	Gatis Paeglis	2019-08-27	1	-3/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	With libxcb 1.11 as minimal required version we can: (a) (Maybe) Enable threaded GL for MESA, see QTBUG-67277. (b) Avoid performance issues described in QTBUG-46017. Bundled xcb libs don't contain the more modern SHM fd passing APIs. The official binaries use "-qt-xcb", therefore we were shipping with the performance fix #ifdef-ed out. (c) Make xcb-xkb a mandatory dependency avoiding issues described in QTBUG-30911. Issues that appear when Qt was configure with "-no-xkb -xcb-xlib", but X server has the XKB extension. (d) Drop all, but xcb-xinput sources from src/3rdparty/xcb/, for which we need "xcb-xinput >= 1.12". This way we can reduce maintenance work. The xcb libraries were origianlly bundled because of lack of availability on supported distributions. This is not the case anymore: CI for Qt 5.13 has: Ubuntu 18.04 - libxcb 1.13 RHEL 7.4 - libxcb 1.13 openSUSE 15.0 - libxcb 1.13 CI for Qt 5.12 has: Ubuntu 16.04 - libxcb 1.11 RHEL 7.4 - libxcb 1.13 openSUSE 42.3 - libxcb 1.11 RHEL 6.x - not relevant because it was dropped from supported platforms. Why 1.11 (released on Aug, 2014), but not 1.13 (released on March 2018)? Based on what we have in CI for 5.13 and 5.14 we could update to 1.13, but it means that Qt would require a very recent version of 3rd party dependency. [ChangeLog][Configure][X11] The minimal required version of libxcb now is 1.11. [ChangeLog][Third-Party Code][X11] Removed all bundled XCB libs, with the exception of xcb-xinput, which is not available on systems with libxcb 1.11. [ChangeLog][Configure][X11] Removed -qt-xcb, -system-xcb, -xkb, -xcb-xinput switches. [ChangeLog][Platform Specific Changes][X11] XKB and XInput2 now are mandatory dependencies for XCB plugin. XCB-XKB is a part of libxcb 1.11 releases. XCB-XInput is not part of libxcb 1.11 releases, but Qt builders can use -bundled-xcb-xinput switch.

*	Add xcb-xinput to 3rd party libs	Alexander Volkov	2018-03-20	1	-0/+14156
	The added xcb-xinput code was produced by build of libxcb 1.13 with xcb-proto 1.13. The following parts were removed from it: - Pointer Barriers API (requires xcb-xfixes 1.9 with xcb-proto 1.9) - SendExtensionEvent API (requires definition of xcb_raw_generic_event_t from libxcb 1.13) [ChangeLog][Third-Party Code] Sources of xcb-xinput 1.13 were bundled and are available via -qt-xcb.
