With debug enabled, g_dbus_connection_call_done() will throw a
g_warning() if the call failed (on purpose or not) while trying to the
serial of a non-existant reply.
(/builds/GNOME/glib/_build/gio/tests/gdbus-connection:26921): GLib-GIO-CRITICAL **: 10:10:16.311: g_dbus_message_get_reply_serial: assertion 'G_IS_DBUS_MESSAGE (message)' failed
This is a reimplementation of commit
4aba03562b from Will Thompson, but
conditional on the caller passing `--glib-min-version 2.64` to
`gdbus-codegen` to explicitly opt-in to the new behaviour.
From the commit message for that commit:
Previously, if a method was not annotated with org.gtk.GDBus.C.UnixFD
then the generated code would never contain GUnixFDList parameters, even
if the method has 'h' (file descriptor) parameters. However, in this
case, the generated code is essentially useless: the method cannot be
called or handled except in degenerate cases where the file descriptors
are missing or ignored.
Check the argument types for 'h', and if present, generate code as if
org.gtk.GDBus.C.UnixFD annotation were specified.
Includes a unit test too.

This can be used by callers to opt-in to backwards-incompatible changes
to the behaviour or output of `gdbus-codegen` in future. This commit
doesn’t introduce any such changes, though.
Documentation and unit tests included.

We got a complaint here that trashing via the
portal deletes the target of a symlink, not the
symlink itself. It turns out that following the
symlink already happens on the glib side.

Even if g_variant_get_va(), which we eventually call, checks on the
validity of the value argument, check it early to avoid surprises, such
as this intermittent FreeBSD test failure:
(/var/tmp/gitlab_runner/builds/3fe11159/0/GNOME/glib/_build/gio/tests/gdbus-connection:65788): GLib-CRITICAL **: 15:13:25.670: g_variant_get_va: assertion 'value != NULL' failed
Skipped tests use "77" as the return value, so return 77 instead of 0
when the static-link.py test gets skipped because of a missing
environment variable.
If the fuse module is loaded but /dev/fuse doesn't exist, it's likely
that we're running in a rootless container, or a badly setup one, and we
won't be able to use fuse, so skip this test.
This happened on my local system using podman running as a normal user,
but this apparently works as expected in our CI[1].

gtk-doc switched from DocBook to Markdown ages ago. There is no Markdown

Add a Python-based test wrapper for the `gdbus-codegen` executable,
similar to the existing tests for `glib-mkenums` and friends.
Add a few basic tests to begin with, but this doesn’t approach anywhere
near full coverage.
The next step is to move the existing Meson-based `gdbus-codegen` tests
from `gio/tests/meson.build` into the Python test suite.

Previously, running `gdbus-codegen` with no arguments would exit
successfully with no output. While technically correct, that seems
unhelpful.
Require at least one interface file to be specified, so the user gets an
error message if they don’t specify any.

It’s not particularly useful to put the gdbus-codegen version or the
name of the input file into the output from `gdbus-codegen`, and it
makes the output less reproducible. Drop it.
Also clarify the licensing.

If not doing this it might happen that the cancelled signal is emitted
between reaching a reference count of 0 and finalizing the GSource, at
which point part of the GSource is already freed and calling any GSource
functions is dangerous.
Instead do this from the dispose function. At this time the GSource is
not partially freed yet and calling any GSource API is safe as long as
we ensure that we have a strong reference to the GSource before calling
any GSource API.
Especially check for a valid reference count. This is possible now in
all cases because of the addition of the dispose function and makes
usage of already finalized/finalizing GSources more obvious than the
use-after-free that would otherwise happen.
This allows GSource implementors to safely clear any other references to
the GSource while the GSource is still valid, unlike when doing the same
from the finalize function.
After the dispose function has run, it is valid for the reference count
of the GSource to be > 0 again to allow the case where another thread in
the mean-time got access to the GSource reference before the dispose
function was called.
This allows fixing a thread-safety issue in the GCancellable, GstBus and
various other GSource implementations.
This doesn’t change how they run, but does split the code out a bit and
mean we can interleave it with comments. Should make it a little less
vile.

This makes things slightly more extensible in future, but introduces no
functional differences right now.

The dockerd instance on some (but not all) GitLab CI runners doesn’t
like the OCI output from the version of podman on Fedora 31, which is
causing a lot of spurious CI failures.
If whoever’s running `run-docker.sh` is using podman to emulate docker,
it needs to be told to output in Docker format, not OCI format.

_kqsub_free assumes the caller has called _kqsub_cancel before calling
it. It checks if both 'deps' and 'fd' have been freed and aborts when
the condition is not met. Since the only caller of _kqsub_free is
g_kqueue_file_monitor_finalize, which does call _kqsub_cancel before
calling _kqsub_free, it seems to be correct for _kqsub_free to assert
values of these two members there.
However, it is possible for _kqsub_cancel to return early without
freeing any resource _kqsub_free expects to be freed. When the kevent
call fails, _kqsub_cancel does not free anything and _kqsub_free aborts
with assertion failure. This is an unexpected behavior, and it can be
fixed by always freeing resources in _kqsub_cancel.
