Make sure to fail consistently in case people created a GPropertyAction
with g_object_new() without passing a property name.
Bindings that construct objects with g_object_new() have no idea if a
property is mandatory.
See: #3130
This avoids a critical warning from trying to disconnect a signal
handler from a `NULL` object if `paction->object` is `NULL` for whatever
reason (see: the following commit).

The `GTK_USE_PORTAL` environment variable has started to be misused by
users, which is causing deployment issues (such as portal services
themselves ending up being forced to use portals, which is never going
to work).
Try and sidestep users’ broken configurations by renaming the
environment variable, and also separating it from the old GTK
environment variable, since the GLib one affects a lot more processes.
This environment variable is meant to be used for
debugging and development, and never in production.
GTK already renamed their environment variable in
https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/4829, so keeping the
`GTK_USE_PORTAL` name in GLib doesn’t make sense anyway.

I had thought that because `g_source_destroy()` was called for the two
sources (cancel and timeout) in the `GTask` finalize function for a
threaded resolver operation, that it would be fine to use a plain
pointer in the source callbacks to point to the `GTask`.
That turns out to not be true: because the source callbacks are executed
in the GLib worker thread, and the `GTask` can be finalized in another
thread, it’s possible for a source callback (e.g. `cancelled_cb()`) to
be scheduled in the worker thread, then for the `GTask` to be finalized,
and then the source callback to continue execution and find itself
doing a use-after-free.
Fix that by using a weak ref to the `GTask` in the source callbacks,
rather than a plain pointer.

`object_path` and `path` were doing exactly the same thing here.

We already validated that the required headers for each type of D-Bus
message were present. However, we didn’t validate that they contained a
variant of the right type. This could lead to functions like
`g_dbus_message_get_path()` returning `NULL` unexpectedly.
This failure could only be hit when using GDBus in peer-to-peer mode, or
with a D-Bus server which didn’t validate the headers itself. The
reference D-Bus server does validate the headers, and doesn’t forward
invalid messages to clients.

Add test cases that result in lookup of the port via
getservbyname().
As the result depends on "/etc/services", it's not reliably the same on
every system. It requires a workaround.
Commit cf55c31170 added a new test which
uses `ptrace()` to check some `GSubprocess` behaviour. FreeBSD uses
different symbol names for ptrace symbols, and we haven’t tested whether
the test works (and reproduces the failure) on FreeBSD, so skip the test

It's not safe to use setlocale() to mutate the locale in a threaded
program. Lots of other tests still do this, and I'm not putting in the
effort to fix them comprehensively in the absense of actual failures on
CI, but I figured it'd be good to fix the tests that I was touching.
This definitely does not do anything on Linux. I bet it's not needed on
other platforms, either. It's unsafe and may crash; there is no safe way
to mutate the environment in threaded programs.
This is a copy of the existing test_l10n, modified to use LC_TIME
instead of LC_MESSAGES. It's not safe as each call to g_setenv() or
setlocale() could cause the test to crash; there is no safe way to
change a threaded process's environment, and a threaded process's locale
can only be safely changed using uselocale(), not with setlocale().
The calls to g_setenv() are definitely not needed on Linux. I wonder
whether removing these will break the test on other platforms?
The calls to setlocale() should be replaced by a dance of
uselocale() -> duplocale() -> newlocale() -> uselocale() on Linux. But
this is not portable and this is a cross-platform test. We would have to
make the test platform-specific to do this. macOS and at least FreeBSD
provide these functions via xlocale.h, but this isn't portable.
It's supposed to be possible to translate settings values using LC_TIME
rather than LC_MESSAGES to determine which translation to use, but
Sebastian Keller noticed that it's not working properly. I've
implemented his proposed solution, which is to actually temporarily
change LC_MESSAGES to match LC_TIME for just as long as necessary to
force gettext to use the desired message catalog.

Following Emmanuele's instructions for use of introspection annotations:
https://www.bassi.io/articles/2023/02/20/bindable-api-2023/
I have audited all uses of the (closure) annotation in glib and
determined that only a handful are correct. This commit changes almost
all of our use of (closure) annotations to conform to Emmanuele's rules.
The test was passing fine when `bindir` was equal to `multiarch_bindir`,
but not when they differ.
For example, on a Debian system, `gio-querymodules` is installed to
`/usr/lib/x86_64-linux-gnu/glib-2.0/gio-querymodules` rather than
`/usr/bin/gio-querymodules` as it is on (say) Fedora.
This was causing the pkg-config tests to fail on Debian.

This reverts commit 004f48f4fc.
Per the discussion on #3356, this change was prompted by a
misunderstanding of ldflags/link_args, and it resulted in various other
packages using glib no longer getting symbols exported. This commit
restores the glib 2.76 behaviour.
Avoid generating more code than needed, so other than continuing using
the generic glib marshallers when possible, define once the custom ones
we need for each file we generate.
The marshallers are then re-used across all the interfaces defined
without duplicating the code size.
This is the same we're doing in code generated by glib-genmarshaller and
what gmarshal does internally.
Since the generated gdbus C code can be considered private too, this is
safe to do, and will allow faster access to GValue objects.
Get rid completely of the usage of the generic marshaller in gdbus
generated code, using instead specific marshallers.
Code is not yet optimized fully since we may still have duplicated
functions to be generated.
Closes: https://gitlab.gnome.org/GNOME/glib/-/issues/3028
We relied on g_cclosure_marshal_generic() to easily generate signal
marshallers, but this relies on inspecting each parameter type with ffi
and this implies a performance hit, other than breaking the stack-frame
unwinder used by Linux perf and so by sysprof.
Given that we know the types we work on, it's easy enough to generate
the marshallers ourself.

For some reason, `time_t` is defined as being 32 bits wide on that
platform, which causes truncation of the timestamps from `struct stat`.
Avoid that problem by consistently using a 64-bit return value from the
`struct stat` accessors.

We were using emit_by_name which implies looking up for the signal name,
while the generated code can easily remember the signal ID and use it
instead, allowing direct access to the signal emission.
`_g_stat_has_field (statbuf, G_LOCAL_FILE_STAT_FIELD_ATIME)` will always
return `TRUE` on Windows (since it uses a basic `struct stat`), so the
platform-inspecific code is equivalent to the Windows-specific code.

`GLocalFileStat` is a platform-specific abstraction around `struct stat`
or `struct statx`. If `struct statx` is available, it will use that by
preference as it has more features.
`glocalfileinfo.c` was, in some places, incorrectly accessing the fields
of `GLocalFileStat` directly rather than through its `_g_stat_*()`
getters. While it correctly accounted for the platform-specific
differences between `st_mtimensec` and `st_mtim.tv_nsec`, it hadn’t been
updated to deal with `stx_mtime`.
On Android, `st_mtimensec` is defined as a fallback for
`st_mtim.tv_nsec` (even though it doesn’t need to be). This caused GLib
to take the `st_mtimensec` code path rather than the `stx_mtime` code
path, and hence try to dereference `st_mtim` in a `struct statx`.
Fix that by correctly using the `_g_stat_*()` getters consistently.

glib-compile-resources --dependency-file= currently generates a depfile
with rules that look like this:
foo.xml: resource1 resource2
This means that if any of the files listed in the GResource manifest
foo.xml change, rebuild foo.xml because foo.xml depends on those files.
This is not useful because the XML manifest is not expected to be a
generated dependency and even if it was, changes to the listed files
would not imply any need to regenerate the manifest. What we really do
need to regenerate is the C source file that is generated by
glib-compile-resources after processing the XML manifest and all the
resource files. That is, the rule should look like this:
foo.c: foo.xml resource1 resource2
as suggested by Hans Ulrich Niedermann in the issue report.

Currently we require explicitly specifying the port when configuring a
proxy server, which is seriously weird. I take the fact that nobody
reported a bug until 2022 to indicate that almost nobody is using
proxies. Whatever. Let's assume that if no port is provided, the default
port for the protocol should be used instead.
For example, you can now specify in GNOME settings that your proxy server
is https://example.com and it will work. Previously, you had to write
https://example.com:443. Yuck!
This was originally reported as GProxyResolver bug, but nothing is
actually wrong there. It's actually GProxyAddressEnumerator that gets
tripped up by URLs returned by GProxyResolver without a default port.
This breaks GSocketClient.
Fixing this requires exposing GUri's _default_scheme_port() function to
GIO. I considered copy/pasting it since it's not very much code, but I
figure the private call mechanism is probably not too expensive, and I
don't like code duplication.

When the gnome test runner executes the tests, the test appear to execute in disk
order. This means it sometimes works and sometimes we see breakage in portal-support-snap
and portal-support-snap-classic.
The issue is that some tests create config files but some don't. If they run
in the wrong order, tests see config files they shouldn't and break.
Fix this by deleting the files after each test run, properly cleaning up after
themselves. The cleanup code is based upon gtestutils.c:rm_rf().

Makes the tests compile using clang with meson directly under
termux on android, this build environment does not approve of
overloading libc symbols.
Fixes: #3008
foo
This is a workaround for build conditions one ends up with under termux,
where the defined __ANDROID_API__ level is lower than what is provided
by gcc installed for it, the libc .so nevertheless contains these symbols
thus enabling the codepaths. This definition is only in use when meson
detected the presence of this symbol in the libc.

In the typical `while (g_file_enumerator_next_file ())` patterns,
there is nothing much checking whether the operation was cancelled
on the GIO side. Unless the user checks for the case, this means
local enumerators always run to completion even if cancelled.
Fix this by checking the cancellable state explicitly for local
enumerators, so there are oportunities for bailing out early if
the enumerator is going through a very large directory.
Note that the prepare callback only has one caller, which pre-initializes
the timeout argument to -1. That may be an implementation detail and not
publicly promised, but it wouldn't make sense to do it any other way in
the caller.
Also, note that g_unix_signal_watch_prepare() and the UNIX branch of
g_child_watch_prepare() already relied on that.
When `copy_file_range()` support was added, I used the definition of
`copy_file_range()` from Linux, which uses `loff_t` to abstract the
different `off*_t` types.
`loff_t` doesn’t exist on FreeBSD, so this doesn’t compile, and was
caught in subsequent asynchronous CI.
Define `loff_t` with a fallback value if it’s not defined, which should
fix this and other uses of `loff_t` in `gfile.c` (for example, if
FreeBSD ever starts declaring `splice()`).
