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.
This commit message was rewritten by @elmindreda to hopefully reflect
the conclusions of the pull request thread.

Closes#1986
(cherry picked from commit 9cd4d2fa20)
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.

The performance counter API is guaranteed to succeed on Windows XP and

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.
(cherry picked from commit cca9008db2)
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.

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 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.
(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.

The EGL backend ignored the state of GLFW_DOUBLEBUFFER and always
created a double-buffered EGL window.
This sets the EGL_RENDER_BUFFER attribute at EGL window creation
appropriately.

(cherry picked from commit 114776a246)
There is no need to enumerate framebuffer configs that will just be
filtered out later by the GLFW_DOUBLEBUFFER hard constraint.
(cherry picked from commit fd79b02840)
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.
Fixes#1873.
(cherry picked from commit 184377b493)
This adds the state part of 04f21abb52
(Make GLFW_DOUBLEBUFFER a window attribute), but without the associated
API change, because this is needed by later bug fixes that will go into
the stable branch.
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.

GLFW_SCALE_TO_MONITOR had no effect on Windows 8.1 up to and including
Windows 10 version 1607 (Anniversary Update), despite those having
support for per-monitor DPI.
That done was to avoid handling systems that have non-client scaling,
introduced in Windows 10 version 1607, without reliable overriding of
the new window size, introduced in Windows 10 version 1703 (Creators
Update). Both are needed to keep the content area at a fixed size for
windows that have GLFW_SCALE_TO_MONITOR disabled.
This change enables window rescaling on Windows 8.1 and all later
versions but disables non-client scaling for unscaled windows on Windows
10 version 1607. Versions after 1607 are unaffected.
Fixes#1511.

Adapted to 3.3-stable from 8b11867464.
On Wayland we implement Client-Side Decorations if the compositors do not
implement SSDs. In that case, the destructors of the surfaces were called
in the wrong order, leading to a dereference of an already freed object.
We need to first destroy the subsurface before destroying the parent surface.

On Windows 7, when GLFW framebuffer transparency and the DWM are enabled
but DWM transparency is disabled (i.e. when the Transparency setting is
disabled under Personalization > Color), the contents of the framebuffer
is combined with the last frame using additive blending instead of
replacing the previous contents.
This commit limits GLFW framebuffer transparency on Windows 7 to when
DWM transparency is enabled, removing the previous workaround of setting
a layered window color key that led to rendering artifacts.
Fixes#1512.

The window decoration window can go away between calls to XQueryPointer,
for example if the GLFW_DECORATED window attribute was just cleared.
(cherry picked from commit ceb20c7f97)
Background: The IM will filter out key events, instead sending exact
duplicate events that are not filtered. It does not send these for
every event, however, so the duplicate events cannot be relied on for
key input. Instead we need to identify and discard them. Since they
are identical, they have the same timestamp as the originals.
The previous duplicate event detection would consume unrelated key
events if the keys were pressed simultaneously, as it only tracked
a single timestamp.
This fixes that issue for any combination of keys, at the expense of
a 1 KB array per GLFW window.
This fix is a stopgap until explicit IME support is done.

The only two EGL implementations on macOS are Swiftshader and ANGLE.
While Swiftshader supports both `NSView` and `CALayer` as
`EGLNativeWindowType`, ANGLE supports only `CALayer`. Furthermore
Swiftshader's OpenGL ES frontend is deprecated in favor of using ANGLE's
Vulkan backend on top of Swiftshader's Vulkan frontend.
This means that on macOS `EGLNativeWindowType` should be a `CALayer` for
compatibility with ANGLE.

This fixes the issue where function keys would be reported as
GLFW_KEY_UNKNOWN if XKB was available and one of the configured keyboard

The non-root parent window owned by the WM could be destroyed before we
process the ConfigureNotify event using the cached parent handle.
Bug was found by unmapping a decorated window.
This like all uses of the Xlib error handler is not thread safe and
there is nothing we can do about that short of moving to XCB.
Fixes#1633.
(cherry picked from commit e65de2941c)
Some synthetic key messages come with a scancode of zero, causing them

If the application is not linked against the Vulkan loader and relies on
a third-party loader library or glfwGetInstanceProcAddress, then our
call to dlopen will fail without a custom dyld environment variable.
This adds a fallback of looking in the directory of the main executable,
which matches the bundle structure recommended by the Vulkan SDK, making
that finally work out of the box for fully dynamic loading.
