A shell one-liner was enough to set GIO_LAUNCHED_DESKTOP_FILE_PID,
but ideally we also want to do the equivalent of sd_journal_stream_fd()
to set up its standard output and standard error streams.
Ideally we would call sd_journal_stream_fd() in a process that will
exec the real program, otherwise it will report the wrong process ID
in the Journal, but we can't easily do that in a forked child when
using posix_spawn() for subprocesses.

In Debian-style multiarch (libdir = lib/x86_64-linux-gnu or similar),
Red-Hat-style multilib (libdir = lib64 or lib) and Arch-style multilib
(libdir = lib or lib32), we have to run a separate version of
gio-querymodules to discover 32- or 64-bit modules on x86. Installing
modules in the directory used for each word size needs to trigger
recompilation of the correct modules list.
Debian, Fedora and Arch currently all have patches to facilitate this:
Debian moves gio-querymodules into ${libdir}/glib-2.0 and provides a
compat symlink in ${bindir}, while Fedora and Arch rename one or both
of the gio-querymodules executables to give it a -32 or -64 suffix.
We can avoid the need for these patches by making this a build option.
Doing this upstream has the advantage that the pkg-config metadata for
each architecture points to the correct executable and is in sync with
reality.
I'm using Debian's installation scheme with a separate directory here,
because the word-size suffix used in Fedora and Arch only works for the
common case of 32- and 64-bit multilib, and does not cover scenarios
where there can be more than one ABI with the same word size, such as
multiarch cross-compilation or alternative ABIs like x32.
Now that we have this infrastructure, it's also convenient to use it for
glib-compile-schemas. This works with /usr/share, so it only needs to
be run for one architecture (typically the system's primary
architecture), but using /usr/bin/glib-compile-schemas for the trigger
would result in either primary and secondary architectures trying to
overwrite each other's /usr/bin/glib-compile-schemas binaries, or a
circular dependency (the GLib library would have to depend on a
common package that contains glib-compile-schemas, but
glib-compile-schemas depends on the GLib library). Installing a
glib-compile-schemas binary in an architecture-specific location
alongside each GLib library bypasses this problem.

Rather than carrying the copylib around inside GLib, which is a pain to
synchronise and affects our code coverage statistics.
This requires updating the CI images to cache the new subproject,
including updating the `cache-subprojects.sh` script to pull in git
submodules.
It also requires adding `gioenumtypes_dep` to be added to the
dependencies list of `libgio`, since it needs to be build before GVDB as
it’s pulled in by the GIO headers which GVDB includes.

It is not only shorter than `not meson.is_cross_build() or
meson.has_exe_wrapper()` but also handle the case of cross compiling to
a compatible arch such as building for i386 on an amd64.
libgamin was last released in 2007 and is dead
[upstream](https://gitlab.gnome.org/Archive/gamin). Distributions may
still ship it (although Fedora no longer does), but we want people to
use inotify on Linux since it’s actively supported.
BSDs use kqueue. Windows uses win32filemonitor.
FAM might still be used on some commercial Unix distributions, but there
are no contributors from those distributions, and certainly no CI for
them to prevent regressions.

Split out from https://gitlab.gnome.org/GNOME/glib/-/merge_requests/2134
by Philip Withnall so it can be used in advance of HTTPS DNS record
support landing.
Reworked to no longer use test fixtures, as it’s simple enough to build
the response header in each test.
The tests are built on Unix only, as they test the parsing code in
`g_resolver_records_from_res_query()`, which is Unix-specific. The
Windows DNS APIs provide much more structured results which don’t need
parsing.
This allows applications to get their value regardless whether glib is a
subproject or pkgconfig:
gio_dep = dependency('gio-2.0')
giomoduledir = gio_dep.get_variable('giomoduledir')
schemasdir = gio_dep.get_variable('schemasdir')
This reverts commit 5aa03882ca.
It fails to compile on newer Meson versions with
`--fatal-meson-warnings` due to:
```
WARNING: Project targeting '>= 0.52.0' but tried to use feature introduced in '0.54.0': variables arg in declare_dependency.
gio/meson.build:833:0: ERROR: Fatal warnings enabled, aborting
```
That happens regardless of the fact that we’ve correctly limited the use
of the `variables` argument to only when building with Meson ≥ 0.56.
Unfortunately Meson can’t statically detect that the argument is
conditional.
Bumping GLib’s Meson dependency is too much work right now, so this MR
unfortunately has to be reverted.
This allows applications to get their value regardless whether glib is a
subproject or pkgconfig:
gio_dep = dependency('gio-2.0')
giomoduledir = gio_dep.get_variable('giomoduledir')
schemasdir = gio_dep.get_variable('schemasdir')
This is intended to provide a uniform interface for controlling whether
the debug output from an application (or service) is emitted, typically
to journald, but actually to wherever the application chooses to output
it.
The main implementation of `GDebugController` is `GDebugControllerDBus`,
which is intended to be used on Linux. Other implementations may be
added in future for other platforms, or larger applications may want to
provide their own implementation which integrates with their ecosystem.
The `GDebugControllerDBus` implementation exposes a D-Bus interface at
`/org/gtk/Debugging` with a method to enable or disable debug
output at runtime.
This could be used by external harnesses, such as GNOME Builder or
systemd, to give a uniform way to get debug output from an application.

Using ld_flags would work, but that does not propagate ldflags to users
of glib. Meson's dependency() call will propagate apple framework
dependencies to downstream users.
This call was needed once upon a time, when GResolver had subclasses
that presumably relied on this. Nowadays, we have only
GThreadedResolver, which does not need it. res_init() is dangerous
because it modifies global state, so let's get rid of it.
The "recursive:" kwarg is available in the targeted minimum version of
meson, and is basically required if you want to not emit warnings and
maybe error with --fatal-meson-warnings.
There are two basic solutions to this problem:
- The current default behavior is false, so explicitly opt in to that
value. None of these internal libraries use recursive objects anyway.
- Use link_with to link to the static library directly, rather than the
extracted objects.
Option 2 is what used to be done before commit
62af03bda8, but it only works with meson
>=0.52 and previously had buggy behavior.
Since the minimum version of meson is now 0.52, it is safe to revert
that commit and go back to using link_with, and therefore option 2 is
chosen.
The variable `gconstructor_code` (which is what’s defined by
`gconstructor_as_data_h`) is not used at all inside
`glib-compile-schemas`.
This looks like a copy/paste error from the build definition for
`glib-compile-resources` below, which does need it.

This will require distributions to ensure they pass
`--localstatedir=/var` correctly to Meson, but they should be doing that
already.

This is a COM object that implements IStream by using a HANDLE
and WinAPI file functions to access the file (only a file; pipes
are not supported). Only supports synchronous access (this is
a feature - the APIs that read from this stream internally will
never return the COM equivalent of EWOULDBLOCK, which greatly
simplifies their use).
This command will try to execute a desktop file, before that
it will load the input as a keyfile for checking its existence
and its validity (as a keyfile).
File arguments are allowed after the desktop file.

Meson 0.54.0 added a new method meson.override_dependency() that must be
used to ensure dependency consistency. This patch ensures a project that
depends on glib will never link to a mix of system and subproject
libraries. It would happen in such cases:
The system has glib 2.40 installed, and a project does:
dependency('glib-2.0', version: '>=2.60',
fallback: ['glib', 'glib_dep'])
dependency('gobject-2.0')
The first call will configure glib subproject because the system libglib
is too old, but the 2nd call will return system libgobject.
By overriding 'gobject-2.0' dependency while configuring glib subproject
during the first call, meson knows that on the 2nd call it must return
the subproject dependency instead of system dependency.
This also has the nice side effect that with Meson >0.54.0 an
application depending on glib can declare the fallback without knowing
the dependency variable name: dependency('glib-2.0', fallback: 'glib').
There were some problems about where to install `gio-launch-desktop` to
support multiarch systems without circular dependencies. Simon McVittie
suggested that, actually, given the current set of platforms supported
by `GDesktopAppInfo` (they’re all POSIX), we could just use `sh`.
That simplifies things nicely. `gio-launch-desktop` can always be
resurrected (and the multiarch debate continued and resolved) if needed
in future.

There were a couple of custom paths which could end up being relative,
rather than absolute, due to not properly prefixing them with
`get_option('prefix')`.
The use of `join_paths()` here correctly drops all path components
before the final absolute path in the list of arguments. So if someone
configures GLib with an absolute path for `gio_module_dir`, that will be
used unprefixed; but if someone configures with a relative path, it will
be prefixed by `get_option('prefix)`.
