When showing a window that had already been shown once (and so already
had its shell objects), GLFW would attach a new buffer and commit it
before waiting for the next configure event. This was a violation of
the XDG shell protocol.
This was allowed to work as intended on GNOME and KDE without error.
However wlroots based compositors would (correctly) emit an error.
Unfortunately, I haven't been able to find a way to get both KDE, GNOME
and Sway to send the configure event we need in order to map the
wl_surface again while keeping our existing shell objects, so with this
commit we now create them for each call to glfwShowWindow and destroy
them for each call to glfwHideWindow.
Fixes#1268
If a window was created as maximized, or created as hidden and then
iconified or maximized before first being shown, that state was lost and
the window was shown as restored.
Content scale events would be emitted when a window surface entered or
left an output, but not when one of a window's current outputs had its
scale changed.
GLFW would report a monitor as connected each time its wl_output
received an update, for example if its scale changed.
This would also cause the monitor to be added to the monitor array
again, causing glfwTerminate to segfault when it attempted to destroy
its already destroyed wl_output.
This is a temporary local fix to have updates to GLFW_DECORATED mostly
work as intended. The whole decoration state machine needs to be
restructured, but not by this commit.
The size limits set on our XDG surface did not include the sizes of the
fallback decorations on all sides, when in use. This led to its content
area being too small.
Related to #2127
The handler for xdg_toplevel::configure treated the provided size as the
content area size when instead it is the size of the bounding rectangle
of the wl_surface and all its subsurfaces.
This caused the fallback decorations to try positioning themselves
outside themselves, causing feedback loops during interactive resizing.

The internal maximization state was not updated when an event was
received that the user had changed the maximization state of a window,
and no maximization events were emitted.
This affected both the GLFW_MAXIMIZED attribute and glfwRestoreWindow.
These changes make GLFW fullscreen more consistent, but unfortunately
also make GLFW even more oblivious to user-initiated XDG shell
fullscreen changes.
Fixes#1995
The current window procedure needs to deal with messages both for user
created windows and the hidden helper window.
This commit separates out the device message handling of the helper
window, allowing both window procedures to be less complicated.
By default, the glfw3native.h header will include the platform-specific
headers necessary for the return types of GLFW native access functions.
Sometimes it is preferrable to declare those types
This commit adds support for the GLFW_NATIVE_INCLUDE_NONE macro, which
when defined disables the inclusion of all platform-specific headers.
Fixes#1348
GLFW did not restore the previous Xlib error handler when removing its
own, instead resetting to the default handler.
This commit saves and restores the previous error handler.
None of this is thread-safe or could ever be.
Fixes#2108
The joystick code did not distinguish between the allocation status of
the GLFW joystick object and whether it is connection to an OS level
joystick object.
These are now tracked separately.
Fixes#2092
The modifier bits for lock keys were only set when the corresponding key
was reported as held down or latched, but not when it was released and
locked.
This avoids glfwCreateWindow emitting GLFW_FEATURE_UNAVAILABLE or
GLFW_FEATURE_UNIMPLEMENTED on Wayland because shared code was calling
unimplemented or unavailable platform functions during final setup.
It also makes it consistent with the final setup of full screen windows.
The code assumed that at least some data would be received via the INCR
mechanism and that, as a result, the string buffer would be allocated.
Bug found by Clang static analysis.
The code assumed that all data offers were selections that supported
plaintext UTF-8.
The initial data offer events are now handled almost tolerably. Only
selection data offers are used for clipboard string and only if they
provide plaintext UTF-8. Drag and drop data offers are now rejected as
soon as they enter a surface.
Related to #2040
The string pointer used to write the contents of our clipboard data
offer was never updated, causing it to repeat parts of the beginning of
the string until the correct number of bytes had been written.
Emitting an error for one specific type of failure in retrieving the
correct name for a display is not very useful, especially when
initialization is otherwise unaffected.
There should be a path for information like that but this isn't it.
Fixes#1791
Operations that take an instance handle should be passed the handle of
whatever module we are inside instead of blindly passing the handle of
the executable.
This commit makes GLFW retrieve its own instance on initialization.
This makes the most difference for window classes, which are
per-instance. Using the executable instance led to name conflicts if
there were several copies of GLFW in a single process.
Note that having this is still a bad idea unless you know what things to
avoid, and those things are mostly platform-specific. This is partly
because the library wasn't designed for it and partly because it needs
to save, update and restore various per-process and per-session settings
like current context and video mode.
However, multiple simultaneous copies of GLFW in a single Win32 process
should now at least initialize, like is already the case on other
platforms.

Alt+PrtSc emits a different scancode than just PrtSc. Since the GLFW
API assumes each key corresponds to only one scancode, this cannot be
added to the keycodes array.
Instead we replace the scancode at the point of entry.
Fixes#1993
This change broke key names for dead keys, because that depends on
the effect on the global state of simulating two key presses.
Issue found by CTest tests.

The normal way of maximizing a window also makes it visible. This
implements window maximization manually for when the window passed to
glfwMaximizeWindow is hidden.
This will very likely not be forward-compatible and should be replaced.
The window content scale correction at creation overwrote the inital,
more pleasant placement of the window by CW_USEDEFAULT, if the window
was created with GLFW_MAXIMIZED set. This is because the translation
to screen coordinates was done using the current position, not the
position from the restored window rect.
A window created maximized and undecorated would cover the whole monitor
Windows placed it on instead of just that monitor's workarea.
This commit adjusts the maximized rect to cover just the workarea,
similar to how undecorated windows that become maximized are handled
during WM_GETMINMAXINFO.
Fixes#1806
The NetBSD sonames for X11 and related libraries is more stable than on
OpenBSD but the version numbers are still bumped more often than their
Linux counterparts, even excluding the one-time version bump across all
X11 related libraries.
This commit moves to using version-less sonames for X11 and related
libraries on NetBSD, which will hopefully be more forward-compatible
than hard-coding NetBSD-specific sonames.
This may not be the correct long-term solution but it runs now.
Binaries also appear to need an LD_LIBRARY_PATH or rpath entry of
/usr/X11R7/lib in order for the libraries to be found by dlopen.
Tested on NetBSD 9.2.
The display sync requests in glfwPostEmptyEvent could just accumulate as
the display was never flushed on secondary threads.
This adds a proper flush after each sync request.
Fixes#1520Closes#1521
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.
Related to #932
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
