We can’t quite use `access()` for this, like `g_file_test()` does, as
`g_file_query_info()` considers a broken symlink to exist, so we need to
match that by passing `AT_SYMLINK_NOFOLLOW`.
We also use the `AT_EACCESS` flag, which makes the `faccessat()` call
cheaper on Hurd.
Systems without `faccessat()` will continue to use the
`g_file_query_info()`-based implementation of `g_file_query_exists()`.
(Commit message rewritten by Philip Withnall.)
g_file_query_exists looks like a simpler and faster api than
g_file_query_info. This vfunc lets us actually make it faster,
and avoid allocations in this frequently used code path.
Remove cmake as we no longer need to build ninja. We can use the
official wheel now since the runner's Python is 3.9 (before: 3.8).
Use the same comment regarding '--wrap-mode' as in the other jobs.
Download and use official ccache binary.
Add myself to the 'only' section in .gitlab-ci.yml so I can have
CI in my fork.
Disable a few deprecation warnings due to the much newer SDK of
the Apple Silicon machine.
Meson 1.5.1 is available in the fd.o SDK and in Debian testing, so the
glib Meson policy says we can update. Update the minimum only as far as
1.4.0 because we don't yet have a need for 1.5.0.
This allows us to:
- Use file.full_path() to avoid deprecation warnings on str.format(file).
- Set c_std=gnu99,c99 to avoid deprecation warnings with gnu99 on MSVC.
Update all the CI builds to use the latest 1.4.x patch release, 1.4.2.
The FreeBSD runner cannot be updated via `gitlab-ci.yml`, so will be
broken for now.
Similarly, the macOS build will not work unless `-Dc_std=gnu99` is
specified at configure time, due to
https://github.com/mesonbuild/meson/issues/13639.
The WSAEnumNetworkEvents API is called every time the socket
needs to be checked for status changes. Doing this in an application
with several sockets could generate a high cpu usage since
this call is done for each socket at each iteration of the main loop.
Since there is also a WSAEvent that gets signaled when there is
a change in the status of the socket, checking its status and
calling the WSAEnumNetworkEvents API only if the event is signaled,
can reduce the overall cpu usage.
The test in `unix-mounts` to see whether `g_unix_mounts_get_from_file()`
can parse an example file was working fine when GLib is built with
libmount, but not when built without it (and hence typically using
`getmntent()`).
This is because libmount supports mountinfo files (like
`/proc/self/mountinfo`), but `getmntent()` only supports mount files
(like `/proc/mounts`). The test was written only with the former.
So, change the test to use mount files when GLib is built without
libmount support.

This kind of deeply nested menu is definitely no longer good UI practice
for most apps (deeply nested menus make things hard to find, and require
good mouse control to navigate). However, it does serve as a good
demonstration of the concepts in `GMenuModel`, so keep it, with a
sentence to acknowledge that it’s not a good UI.

These tests are expected to cause a thread to deadlock. That seems to be
fine with glibc on Linux, but the glibc version on FreeBSD can detect
the deadlock, and aborts the whole test process with:
```
GLib (gthread-posix.c): Unexpected error from C library during 'pthread_mutex_lock': Resource deadlock avoided. Aborting.
```
This is fair enough.
To avoid this causing the test suite to fail, run those two tests in
subprocesses. This also means we’re not carrying a deadlocked thread
around for the rest of the test suite.

Provide examples of what they all represent, and expand on the
descriptions of them in a few places.
Move references to their equivalents from `GnomeVFS` to lower down in
the documentation, since `GnomeVFS` has been deprecated for many years
now, and is unlikely to be pertinent to most readers.

When listing schemas from a specified directory, explicitly
create the GSettings object from the schema, don't allow g_settings_new
to do the usual lookup. That lookup fails if no other schemas are
installed in the default directories.
Fixes#3429.
This can never have been tested, it was returning `GUnixMountEntry`
structs from functions which are typed to return `GUnixMountPoint`s.

While GLib doesn’t parse these files, it does provide API to access the
fields from them, and does implement some logic based on options fields
in them. It would be nice to be able to test that, and get coverage of
the methods for `GUnixMountPoint` and `GUnixMountEntry`.
We don’t expect users to start querying the fstab or mtab by explicitly
loading data from those file paths. These functions are mainly intended
to prove a controllable entry point into the `gunixmounts.c` code for
unit testing.
It means we can provide a file with controllable contents in order to
test the mount entry/point code on.

You may not always know which schemes are available.
The library should not bail out, but only show
an informal message. It's the responsibility of
the application to deal with invalid URI schemes.
The test brings a Finder window to the front. It's not ideal,
but I have no better idea at the moment. It would be cool if we
can make the test case register itself as handler for a particular
uri scheme, but I have no idea how to do that.
I answered a question on irc about withdrawing notifications, and
when I handed out a link to the GApplication docs, I noticed we
don't have this function name linkified. Fix that.
On Wayland the activation token returned by
`g_app_launch_context_get_startup_notify_id()` doesn't depend on the
`GAppInfo`. The token is only used to hand over focus to the
application that is launched. In some cases it's not even possible to know
what application will actually be used to open the files. For example
when using portals within a sandbox. Therefore, allow providing no
`GAppInfo`.
This also makes clear in the docs that the `files` argument can be `NULL`.
We want to add the support for the activation token, to get it we use
`g_app_launch_context_get_startup_notify_id` which takes a list of
files, so that we don't have to create a GFile twice simply change the
signature of the functions. Fortunately this isn't a public API.
This file doesn’t contain any real implementation, it just call the
`impl` functions from the platform-specific files
`gcontenttype-{fdo,osx,win32}.[cm]`.
It serves as a location for the doc comments, introspection annotations
and API preconditions, and will be built on every platform. In
particular, this means that we get consistent GIR output for the
`g_content_type_*()` APIs regardless of whether GLib was built on Linux or
Windows or macOS.
