The conversion of window icon image data involves unsigned char color
values being promoted to int and then shifted to the left by 24. For
32-bit ints this is just far enough to trigger undefined behavior.
It worked by accident because of how current compilers translate this
piece of code.
This was caught by @slimsag while working on [Zig bindings for GLFW][1],
and diagnosed together with @Andoryuuta, as described [in an
article][2]. Zig has UBSan enabled by default, which caught this
undefined behavior.

Thanks to Maato, martinhath, dcousens, drfuchs and Validark for helping
to refine the solution.

Closes#1986
(cherry picked from commit 9cd4d2fa20)
This docstring previously indicated that GLFW_CONTEXT_REVISION was
a window hint and attribute, but in fact it is only a window attribute
(there is no code which uses this constant in any other context.)
We noticed this in https://github.com/hexops/mach/pull/71/files#r749741814Closes#1992

(cherry picked from commit 37fc28bff6)
Add GLFW_FORMAT_UNAVAILABLE to the list of possible errors in the
reference documentation for glfwGetClipboardString.
Slightly edited by @elmindreda.
Closes#1998
(cherry picked from commit bb193325cc)
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
Looking into the definition of kIOMainPortDefault, the following
description can be found:
When specifying a main port to IOKit functions, the NULL argument
indicates "use the default". This is a synonym for NULL, if you'd
rather use a named constant.
Thus, we do not have to utilize an external symbol for the identifier
of the default main IOKit port, but MACH_PORT_NULL suffice. This
simplifies compatibility between macOS versions as the symbol was
renamed with macOS 12.0.
Fixes#1985Closes#1994
(cherry picked from commit 544790666b)
This adds a workaround for kIOMasterPortDefault having been deprecated
in favor of kIOMainPortDefault in macOS 12.0.
Closes#1980
(cherry picked from commit f75c251dec)
The GLFW_INCLUDE_GLCOREARB branch was left out when GLFW_INCLUDE_GLEXT
was originally added, for reasons that are lost to history. The current
versions of these headers seem to co-exist just fine.
Issue reported on IRC.
(cherry picked from commit 309d79376f)
The performance counter API is guaranteed to succeed on Windows XP and
later so there is no need for a fallback.
This removes our last dependency on winmm.
(cherry picked from commit b6834bf2a1)
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.

This sentence was truncated by 951a9583fa
and then not updated when content scale support was added with

(cherry picked from commit 6a20053102)
There is a suppression interval (0.25 seconds by default) after a call
to CGWarpMouseCursorPosition, during which local hardware events
(keyboard and mouse) are ignored. GLFW already calls
CGEventSourceSetLocalEventsSuppressionInterval with a value of 0.0, but
it doesn't help in this case, there is still a short delay before the
cursor can be moved. Moving the CGAssociateMouseAndMouseCursorPosition
call after the cursor position has been restored, fixes the issue.
Closes#1962
(cherry picked from commit 157ebb80aa)
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.

Variables in CMake if-statements (and only in if-statements) do not need
to be explicitly dereferenced; a thing I did not always know.

The _glfwPlatformSetWindowFloating function would return without freeing
the state array if the window was already in the requested state.
(cherry picked from commit 071d7c0f46)
The outer glfwUpdateGamepadMappings function is now bypassed when
parsing the default gamepad mappings. The data in mappings.h does not
contain any comments or line breaks. Also this is done before joystick
support has been initialized, so there is no need to look for matching
devices.
Finally, the array of default mappings is pre-allocated. This has no
measurable performance impact but does generate a lot of calls, which
won't be nice for a user provided custom allocator to deal with.
(cherry picked from commit 201400b974)
This fixes gamepad mappings being included in GLFW binaries that would
then never use them because they were for a different platform.
(cherry picked from commit 0c90e1a33f)
This avoids generating a macro redefinition warning when the
GL_SILENCE_DEPRECATION macro has been defined for the whole of a larger
project.
Closes#1840.
(cherry picked from commit 1d88a2e3d6)
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.
