There is a seemingly unavoidable race condition when waiting for data on
the X11 display connection, as long as any other thread is also making
Xlib calls. The event data we are waiting for could be read by the
other thread as part of looking for the reply to its request, before our
poll has begun.
This commit replaces the X11 event sent by glfwPostEmptyEvent with
writing to an unnamed pipe. The race condition remains if other Xlib
calls are made on other threads, but glfwPostEmptyEvent should now be
race-free.
This commit is based on work by pcwalton, OlivierSohn, kovidgoyal and
joaodasilva.

The data available on the X11 connection may be a reply or an internal
event for an X11 extension. Previously the check for whether an event
was available for us was done outside waitForEvent. This prevented data
available on other file descriptors from breaking the outer wait loop.
This commit moves the check for whether an event is available into the
wait functions, where there is enough knowledge to limit the check to
the X11 connection.

On Linux, the inotify descriptor was included in the set used for
select, but could not break the outer loop, leading to busy waiting
until timeout or the correct X11 event arrived.
This commit adds a new function for waiting just on X11 events.
Fixes#1872
(cherry picked from commit 1e987cb92e)
This replaces select with poll for checking for data on event file
descriptors, as select cannot handle file descriptors larger than 1023.

We switched to kUTTypeURL when NSURLPboardType was deprecated, as the
official replacement symbol NSPasteboardTypeURL was not available on
every version of macOS supported by GLFW.
kUTTypeURL has now also been deprecated.
This commit moves to a compile-time choice between NSURLPboardType and
NSPasteboardTypeURL depending on the minimum targeted macOS version.

By definition a hidden window on Wayland does not have valid framebuffer
contents.
This adds a window damage (refresh) event when a window is shown, to
request an initial frame for the now visible window.

Platform code should not generate key events with GLFW_REPEAT.
GLFW_PRESS is translated into GLFW_REPEAT by shared code based on the
key state cache.
This confused the automatic key release logic into not generating an
event with GLFW_RELEASE for a key being repeated when the window lost
input focus.
(cherry picked from commit 3f5dfeaf29)
The OpenBSD ports tree assigns its own soname version numbers, so the
hardcoded sonames GLFW uses to load libraries on non-macOS Unices are
often incorrect. Instead OpenBSD recommends that run-time loading
should leave out the version numbers entirely. The OpenBSD ld.so then
finds the correct library.
This upstreams the ports tree fixes for Xcursor and EGL, and adds the
corresponding fix for all other run-time loaded library sonames.
Tested on OpenBSD 7.0.
This issue was initially reported on IRC.

Corrects the protocol violation when creating an xdg_surface from a
wl_surface that already has a buffer due to EGL buffer swaps.
This commit is based on PR #1731 by @ghost, but adapted and altered:
- The XDG surface and role are now only created when a window is shown
to prevent application lists from showing command-line applications
with off-screen-only windows
- The special case of Wayland+EGL buffer swap is now in the EGL code
to mirror how X11 is handled
- Adaption to run-time platform selection and separate credits file

If a window lost input focus while a key was held down, the key repeat
mechanism would resume once the window regained focus.

In the case the key repeat timerfd was interrupted before read(), the
cursor timerfd wasn’t read at all even when it could.

The monitor handle could have become invalid just before the call to
GetDpiForMonitor. It was possible for both window and monitor content
scale queries.
This ensures both that an appropriate error is emitted and that the
retrieved values are zero on error.

Joysticks already connected when GLFW was initalized did not get gamepad
mappings applied to them.
Regression introduced by 74a8ba26c3.
This change was backported without taking into account that 3.3.x does
not have on-demand joystick init.
Fixes#1996
The native access functions for context handles did not verify that the
context had been created with the same API the function was for.
This makes these functions emit GLFW_NO_WINDOW_CONTEXT on API mismatch.

The Wayland protocol spec[1] states that set_cursor must be called
with the serial number of the enter event. However, GLFW is passing in
the serial number of the latest received event, which does not meet the
protocol spec.
[1] https://wayland.freedesktop.org/docs/html/apa.html#protocol-spec-wl_pointer
As a result, set_cursor calls were simply ignored by the compositor.
This fix complies with the protocol more closely by specifically caching
the enter event serial, and using it for all set_cursor calls.

According to the libxkbcommon documentation[1], xkb_keymap_key_repeats
requires keymap and keycode as input:
int xkb_keymap_key_repeats( struct xkb_keymap * keymap,
xkb_keycode_t key)
However, in inputChar in wl_input.c we are passing in xkb_keysym_t,
which was a type mismatch.
This results in some keys not repeating when they should and vice versa.

The _glfwPlatformSetWindowFloating function would return without freeing
the state array if the window was already in the requested state.

The contents scale of the hosted CAMetalLayer created for MoltenVK was
updated only after the GLFW content scale and framebuffer size events
were emitted, causing the layer to get out of sync with the monitor the
window was on.
(cherry picked from commit 076bfd55be)
Because there are controllers in the wild using the same hardware ID
despite having different numbers of buttons and axes, an error message
was triggered that was only expected for a corrupted mapping database.
This removes the error for now, in preparation for better error handling
for gamepad mappings overall.
Fixes#1763.

Some URLs in the documentation were overlooked during the switch to

The old Travis CI .org service has been throttled for a while now and is
said to be shutting down completely next week.
This migrates the Travis CI build jobs to GitHub Actions, with minor
changes.
- The trailing whitespace detection has been removed for now.
- The libegl1-mesa-dev dependency for Wayland has been removed as it
appears to no longer be necessary for building.

This skips the buffer swap after the initial glClear performed during
window creation, if the window is single-buffered. This call confused
apitrace into thinking the window was double-buffered.

The /clang: suffix passed to Clang-CL was accidentally also passed to
the regular standalone Clang, which caused compilation to fail. We now
pass /W3 to Clang-CL, which it interprets as -Wall.
The _CRT_SECURE_NO_WARNINGS macro is now defined for both Clang and
Clang-CL.
The /entry: flag passed to link.exe is now also passed to lld-link,
letting the windows subsystem tests and examples link.
