This adds the glfwInitAllocator function for specifying a custom memory
allocator to use instead of the C runtime library.
The allocator is a struct of type GLFWallocator with fields
corresponding to malloc, realloc and free, while the internal API
corresponds to calloc, realloc and free.
Heap allocation calls are filtered before reaching the user-provided
functions, so deallocation of NULL and allocations of zero bytes are not
passed on, reallocating NULL is transformed into an allocation and
reallocating to size zero is transformed into deallocation.
The clearing of a new block to zero is performed by the internal
calloc-like function.

This adds the GLFW_LIBRARY_TYPE CMake cache variable, which allows users
and higher-level projects to set what type of library GLFW is built as.
When not empty, this value overrides the standard BUILD_SHARED_LIBS
option for GLFW while still allowing it to control the type of other
libraries in a larger project.
This also allows building GLFW as an object library without adding dummy
source files (as required by Xcode) or producing unused library
binaries.
Projects using CMake 3.12 or later can link the resulting GLFW object
library normally using target_link_libraries.

The insight to use wayland.xml to resolve the difficult-to-redirect
interface symbols was gleaned from SDL.
Instead of compiling the code output of wayland-scanner separately it is
made part of the wl_init compilation unit. This lets us do things like
transparently rename our copies of Wayland globals.
The OS version of wayland-client-protocol.h is no longer used by GLFW,
but it is presumably ABI compatible with the output of wayland-scanner.

POSIX.1-2008 deprecated gettimeofday, which we used as a fallback if the
monotonic clock was unavailable.
This replaces that fallback with the non-monotonic real-time clock.
Because of the Gordian knot of feature test macros across Unices, this
also includes the shift from some platform source files defining
_POSIX_C_SOURCE to various values to _DEFAULT_SOURCE being defined for
all source files on Linux. This is because -std=c99 on Linux disables
_DEFAULT_SOURCE (POSIX 2008 and extensions).
Once runtime platform selection comes in, this kind of platform-specific
preprocessor logic can be moved into the platform glue files and won't
need to be replicated by third-party build setups, but for now, sorry.
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.
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.
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.
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.
Fixes#1843.
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

Clang-CL.
The /entry: flag passed to link.exe is now also passed to lld-link,
letting the windows subsystem tests and examples link.

The GPU driver only looks in the executable for the symbol requesting

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.

On Wayland we implement Client-Side Decorations if the compositors do not

An incorrect value for _WIN32_WINNT_WINBLUE caused GLFW to think Windows

SetProcessDpiAwareness.
Closes#1775.
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.

Returning HTTRANSPARENT from WM_NCHITTEST does cause the window to be
transparent for some hit-testing APIs but does not make it pass mouse
input through to whatever window is below it.
For that to work on modern Windows, the window needs to be both layered
and extended-window-style-transparent.
Additional logic changes to ensure mouse input passthrough, framebuffer
transparency and window opacity are mindful of one another when
modifying WS_EX_LAYERED.

It seems it has not been possible to compile GLFW on systems without the
UTF-8 extensions to Xlib since a0a5cc57df
was merged five months ago. The UTF-8 extension functions were
introduced with XFree86 4.0.2 in December 2000 and are likely widely
available at this point.
This removes the locale-dependent fallback paths and uses the UTF-8
extension functions where available.
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.

This makes the null platform behave more like an actual stub. More
queryable state is tracked and there is even a fake monitor with one
whole fake video mode.
This fixes a race between the key repeat logic and the surface leave
event handler, which could result in repeated keys being reported with
a window of NULL.
Fixes#1704.
This adds two new error codes: GLFW_FEATURE_UNAVAILABLE for when
a GLFW feature cannot be reasonably implemented on that platform, and
GLFW_FEATURE_UNIMPLEMENTED for when it can be but has not been yet.
This replaces the current situation where the Wayland code emitted
GLFW_PLATFORM_ERROR in both cases while the macOS code silently did
nothing.
If your application exits on any GLFW error, these error codes should at
least be easy to filter out from that behavior.
Ideally, GLFW_FEATURE_UNAVAILABLE should be rare and
GLFW_FEATURE_UNIMPLEMENTED should never be emitted at all.
Fixes#1692.
These are harmless errors but the code was worth fixing just to reduce
confusion and be more explicit. E.g. using a different variable name

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.

A regression introduced by b889aa7841

The non-functional remains were later removed. This restores the

This fixes the issue where function keys would be reported as
GLFW_KEY_UNKNOWN if XKB was available and one of the configured keyboard
layouts was Arabic.
This is only part of #1598, because the full patch removed parts of the
fallback path for when XKB is unavailable.

The non-root parent window owned by the WM could be destroyed before we
process the ConfigureNotify event using the cached parent handle.

This adds support for the XIM instantiate and destroy callbacks, letting

This moves the remaining bits of NSApplication initialization into
_glfwPlatformInit. As a side-effect of this, any command-line program
initializing GLFW will get a menu bar, which is not ideal.
If this has happened to you and a bisect led you here, please see the
GLFW_COCOA_MENUBAR init hint introduced in GLFW 3.3.
If this patch is a terrible idea, please get in touch in the 3.4 release

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.
When the WM does not support EWMH or there is no WM running, GLFW falls
back to XSetInputFocus, which will emit BadMatch if the window is not
viewable, which will terminate the program.
Bug spotted on IRC.
A window resize action that also resulting in the window being moved did
not emit any window positions events, as the position of real
ConfigureNotify events was ignored. The real events use parent
coordinates instead of root coordinates so this adds parent tracking and
conditional translation.

This removes the final dependency on CoreVideo, using a display link to
get the refresh rate of monitors where Core Graphics report a refresh
rate of zero. Instead we now query the I/O registry directly, similarly
to what the display link does at creation.
Thanks to @OneSadCookie for pointers to this solution.
The display link query is not specific to any particular display mode
and so only needs to be done once.
The next step is to replace the display link altogether by querying
IOKit directly, which is what the display link does.
CLOCK_MONOTONIC should not be used as a feature macro. The POSIX
feature macros are provided by unistd.h. CLOCK_MONOTONIC is provided by
time.h. CLOCK_MONOTONIC requires _POSIX_C_SOURCE >= 199309L on some
systems.
Polling the event queue before NSApp had been allowed to finish
launching, in our case by starting our self-terminating run loop,
triggered an assertion inside NSApplication.
This fix, which makes all event processing functions capable of starting
it, makes that assertion less likely.
A more Cocoa-friendly fix would be to finish launching NSApp during
glfwInit and let people annoyed by the menu bar disabled it with
GLFW_COCOA_MENUBAR. That may not be suitable for 3.3-stable, though.
Fixes#1543.
That way the application only sees the cursor moving when it is inside
of its area, it won’t go back to the top or left side when trying to
resize the window or just hovering the fallback decorations.
Previously, any pointer motion in the window decorations when using the
fallback implementation would obtain the wl_cursor again, and do the
attach danse for no benefit.
This will ultimately allow animated cursors to not reset to the first
frame on motion, once these will be implemented.
This falls back to calculating the monitor physical size from the
current resolution and the default X11 DPI when the physical size
returned by RandR is zero.
On macOS a destroyed window remained on screen until the next time
events were processed. This makes the behavior more consistent with
other platforms.

For users with multiple keyboard layouts configured, glfwGetKeyName

MSVC 2019 complains that the code at line 1744
(`GetMonitorInfo(window->monitor->win32.handle, &mi);`) can potentially
dereference a null pointer. The compiler is wrong in this case (it has

I think it makes sense for our non-NULL test to be on the variable we
actually use rather than the one it was set from.

The EWMH feature detection atoms are now named and loaded the same way
as other X11 atoms. Detection is now performed after all
non-conditional atoms have been loaded. The EWMH detection now has
hopefully more readable comments.
This protocol is part of the core Wayland, but it is pretty badly
designed and is missing quite a few features, and is in the process of
being phased out in compositors. Its support in GLFW requires
duplicating pretty much every single window management codepath.
This bumps the required compositor versions to the ones which have
implemented xdg-shell, approximately two years ago, which seems sensible
to me.
Window relative mouse locations provided via NSWindow and NSEvent are
based at 0,1 while screen relative locations use 0,0. Incorrect
handling of this had crept into other coordinate transformations. Note
that most of these errors canceled each other out, so the reported
positions of windows, monitors and work areas are unaffected. This
corrects the cursor position for glfwGetCursorPos and glfwSetCursorPos.

This allows compositors which prefer to draw the decorations around
clients to do so, rather than letting GLFW draw its own decorations.
The appearance is thus entirely subject to the compositor used, but
should generally be better than the current solid colour decorations we
have, which we continue to use when the compositor doesn’t support this
protocol or tells us to draw the decorations ourselves.
This new protocol has been tested against wlroots’s rootston compositor.
Fixes#1257.
This allows the compositor to avoid having to setup and teardown a
SIGBUS signal handler whenever it needs to read from this surface, as it
knows we won’t be able to shrink the file and so doesn’t have to protect
against that.
This codepath will only be used on Linux ≥ 3.17 with glibc ≥ 2.27, and
possibly other kernels and libc. The former code will continue to be
used as a fallback, either if memfd_create() fails or if it isn’t
available.
This adds the GLFW_SCALE_TO_MONITOR window hint for automatically
resizing the content area of a window to the requested size times the
