The Wayland backend was the only one where half the window and input
related code was in the init module. As those bits want to share more
utility code with the window module, the interface between them grows.
To prevent that, this gathers nearly all window and input related code
into the window module.
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.
If the polling was interrupted by a signal or by incomplete or unrelated
data on any file descriptor, handleEvents could return before the full
timeout had elapsed.
This retries the Wayland prepare-to-read and poll until the full timeout
has elapsed or until any event was processed. Unfortunately, due to how
the Wayland client API is designed, this also includes the delete_id
for the frame callback created by eglSwapBuffers.
This means glfwWaitEvents* are still not fully functional on Wayland.
See #1911 for more details.
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.

This moves the X11 polling implementation to a separate file where it
can be used by either the X11 or Wayland backend or both.
This code should be POSIX compatible where necessary but will use the
lower latency but non-standard polling functions ppoll or pollts where
those are available.
This commit is based on work by OlivierSohn and kovidgoyal.

Cancel the prepared-to-read state on the calling thread before starting
to call back to user code.
Emitting close requests here is not a good choice but that is for
a future commit to address.
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.
A window created with GLFW_VISIBLE set was not made visible by the
initial buffer swap during context attribute refresh.
Regression introduced by @elmindreda in
094aa6d3c7.
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.
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
Fixes#1492Closes#1731
This adds compile-time support for multiple platforms and runtime
detection of them. Window system related platform functions are now
called from shared code via the function pointer struct _GLFWplatform.
The timer, thread and module loading platform functions are still called
directly by name and the implementation chosen at link-time. These
functions are the same for any backend on a given OS, including the Null
backend.
The platforms are now enabled via CMake dependent options following the
GLFW_BUILD_<platform> pattern instead of a mix of automagic and ad-hoc
option names. There is no longer any option for the Null backend as it
is now always enabled.
Much of the struct stitching work in platform.h was based on an earlier
experimental branch for runtime platform selection by @ronchaine.
Every platform function related to windows, contexts, monitors, input,
event processing and Vulkan have been renamed so that multiple sets of
them can exist without colliding. Calls to these are now routed through
the _glfw.platform struct member. These changes makes up most of this
commit.
For Wayland and X11 the client library loading and display creation is
used to detect a running compositor/server. The XDG_SESSION_TYPE
environment variable is ignored for now, as X11 is still by far the more
complete implementation.
Closes#1655Closes#1958
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.
