Some filesystems do not support fallocate and return EOPNOTSUPP.
On musl-based distros libwayland-cursor exits abruptly which causes the
application to crash. Unlike glibc, musl does not provide a fallback
mechanism for handling unsupported fallocate. Instead, musl developers
argue that application should handle the case of unsupported system
call.
This commit allows falback to ftruncate in case when EOPNOTSUPP
was recieved.

The new test verifies that, for a set of timers and a short sequence
of timer update calls, when the event loop is run the timer callbacks
are run in the expected order.
Signed-off-by: Manuel Stoeckl <code@mstoeckl.com>
libwayland now uses only one file descriptor to keep track of all
the timer event sources associated with an event loop. An array-based
binary heap is used to determine which event source has the earliest
deadline.
(Previously, each timer event source had its own timerfd, making it easy
for the a process using many timer event sources to run out of file
descriptors.)

This change expands the `event_loop_timer` test to use two different
timers with different timeouts; it now implicitly checks that e.g.
both timers do not expire at the same time, and that the first timer
expiring does not prevent the second from doing so. (While such failure
modes are unlikely with timer event sources based on individual
timerfds, they are possible when multiple timers share a common timerfd.)
Signed-off-by: Manuel Stoeckl <code@mstoeckl.com>
The implementation of timer event sources based on timerfds ensured
specific edge-case behavior with regards to removing and updating timers:
Calls to `wl_event_loop_dispatch` will dispatch all timer event sources
that have expired up to that point, with one exception. When multiple
timer event sources are due to be dispatched in a single call of
`wl_event_loop_dispatch`, calling wl_event_source_remove` from within a
timer event source callback will prevent the removed event source's
callback from being called. Note that disarming or updating one of the
later timers that is due to be dispatched, from within a timer callback,
will NOT prevent that timer's callback from being invoked by
`wl_event_loop_dispatch`.
This commit adds a test that verifies the above behavior. (Because
epoll_wait is not documented to return timerfds in chronological order,
(although it does, in practice), the test code does not depend on the
order in which timers are dispatched.)

While the default Unix socket buffer size on Linux is relatively
small, on some computers the default size may be configured to
be huge, making the overflow test never actually overflow the
Wayland display socket.
The changed code now explicitly sets the display socket send buffer
size to be small enough to guarantee an overflow.

This change ensures that the compositor process is not able to respond
to any of the noop requests sent by the client process, by using the
test compositor's `stop_display` mechanism to coordinate when the
compositor should stop processing messages.

wl_event_loop_dispatch in the compositor process could respond to all
the client's noop requests before returning.)

Meson is a next generation build system, simpler than Autotools and also faster
and more portable. Most importantly, it will make integrating ASan easier in
CI.
The goal is to maintain feature parity of the Meson build with the
Autotools build, until such time when we can drop the latter.
Add a script which generates the desired Doxygen configuration for our various
output formats and executes it using that configuration. This is not something
Meson can or should do.

The tests that run exec-fd-leak-checker expect the binary to be located
in the current directory. This is not always the case; for instance, the
binaries could be built under `tests`, but be invoked under the
top-level build directory.
We can use an environment variable to control what's the location of the
test binaries, and fall back to the current directory if the variable is
unset.

Make considers a variable called VPATH when trying to satisfy
dependencies, e.g. for a target 'foo', it will consider the target
extant if VPATH is '../../bar' and '../../bar/foo' exists.
Part of the doc build, the '$(alldirs)' target, exists to create the
target directories if they do not exist. For example, before generating
xml/wayland-architecture.png, it will ensure the 'xml' target is
considered up-to-date thanks to the target dependency.
Creating $(srcdir)/doc/doxygen/xml thus means that the 'xml' dependency
will be satisfied, so we'll never create the output directory, and the
doc build will fail.
Change the alldirs target list to be absolute paths, so VPATH will not
be consulted and defeat the entire point of what we're trying to do.
This fixes the Meson build, where we later create
doc/doxygen/xml/meson.build.

Including wayland-server-core.h in wayland-private.h is problematic
because wayland-private.h is included by wayland-scanner which should be
able to build against non-POSIX platforms (e.g. MinGW). The only reason
that wayland-server-core.h was included in wayland-private.h was for the
wl_private_signal definitions, so move those to a
wayland-server-private.h file that can be included by both
wayland-server.c and the tests.

This test makes sure that after wl_global_remove:
* The global_remove event is sent to existing clients
* Binding to the removed global still works
* A new client will not see the removed global advertised
Signed-off-by: Simon Ser <contact@emersion.fr>
This commit adds a new wl_global_remove function that just sends a global
remove event without destroying it. See [1] for details.
Removing a global is racy, because clients have no way to acknowledge they
received the removal event.
It's possible to mitigate the issue by sending the removal event, waiting a
little and then destructing the global for real. The "wait a little" part is
compositor policy.

If a client set the F_SEAL_SHRINK seal on the fd before passing it to

When implementing a workaround for [1], one needs to accept a global to be
bound even though it has become stale.
Often, a global's user data is free'd when the global needs to be destroyed.
Being able to set the global's user data (e.g. to NULL) can help preventing a
use-after-free.
(The alternative is to make the compositor responsible for keeping track of
stale user data objects via e.g. refcounting.)

The new display test runs a client that makes a very large number of
trivial requests. After responding to initial setup requests, the server
is paused, letting the trivial requests fill up the Unix socket buffer,
making further writes to the socket fail. The test then checks that the

Once there has been a fatal display error, any new object requests
potentially rely on invalid state. (For example, a failure to read
from the compositor could hide a important event.) The safest way to
handle the new requests is not to make them.
Proxies produced by the request are still created, to ensure that
any code using the library does not crash from an unexpected NULL
pointer.

Add a comment to wl_shm.format to advise contributors to use the automated
script (generate-shm-formats.py) instead of updating the list manually.
Signed-off-by: Simon Ser <contact@emersion.fr>
This prevents mismatches and missing formats between wl_shm.formats and
drm_fourcc.h.
The script collects DRM_FORMAT_* constants from drm_fourcc.h, compares the list
with the current wayland.xml entries (checking for any mismatch) and then
appends missing entries to wayland.xml.
Enum values are obtained by executing a generated C file which prints the
constants. There is no other reliable way to get these values as they are
defined via various macros.
There is no widespread Python library able to parse an XML file and format it
with all whitespace preserved. For this reason, we don't use an XML library to
create the new XML elements. Instead, we keep track of the line number of the
last wl_shm.format enum entry and add new entries right after. To be able to
read the line number of an element, we use lxml (the standard library doesn't
retain line number information).
