Like G_SOURCE_REMOVE and G_SOURCE_CONTINUE, these make it clearer what
it means to return TRUE or FALSE.
In particular, in GDBus methods that fail, the failure case still needs
to return TRUE (unlike the typical GError pattern), leading to comments
like this:
g_dbus_method_invocation_return_error (invocation, ...);
return TRUE; /* handled */
which can now be replaced by:
g_dbus_method_invocation_return_error (invocation, ...);
return G_DUS_METHOD_INVOCATION_HANDLED;
G_DBUS_METHOD_INVOCATION_UNHANDLED is added for symmetry, but is very
rarely (perhaps never?) useful in practice.

There is already g_unix_mount_at function which allows to find certain
unix mount for given mount path. It would be useful to have similar
function for mount points, which will allow to replace custom codes in
gvfs. Let's add g_unix_mount_point_at.
This is a new version of the g_file_set_contents() API which will allow
its safety to be controlled by some flags, allowing the user to choose
their preferred tradeoff between safety (`fsync()` calls) and speed.
Currently, the flags do nothing and the new API behaves like the old
API. This will change in the following commits.

This will allow to further enhance the parsing, without breaking API,
and also makes argument on call side a bit clearer than just TRUE/FALSE.

Add some internal wrappers around sysprof tracing, so that it can be
used throughout GLib without exposing all the details of sysprof
internally.
This adds an optional dependency on `libsysprof-capture-4`. sysprof
support is disabled without it.
This depends on the GLib dependency of `libsysprof-capture` being
dropped in https://gitlab.gnome.org/GNOME/sysprof/-/merge_requests/30,
which has bumped the soname of `libsysprof-capture` and added subproject
support.
The next few commits will add marks that trace out each `GMainContext`
iteration and each `GSource` `check`/`prepare`/`dispatch` call.

Add a set of new URI parsing and generating functions, including a new
parsed-URI type GUri. Move all the code from gurifuncs.c into guri.c,
reimplementing some of those functions (and
g_string_append_uri_encoded()) in terms of the new code.

This was mostly machine generated with the following command:
```
codespell \
--builtin clear,rare,usage \
--skip './po/*' --skip './.git/*' --skip './NEWS*' \
--write-changes .
```
using the latest git version of `codespell` as per [these
instructions](https://github.com/codespell-project/codespell#user-content-updating).
Then I manually checked each change using `git add -p`, made a few
manual fixups and dropped a load of incorrect changes.
There are still some outdated or loaded terms used in GLib, mostly to do
with git branch terminology. They will need to be changed later as part
of a wider migration of git terminology.
If I’ve missed anything, please file an issue!

These are alternatives to the existing `time_t`-based APIs, which will
soon be deprecated due to `time_t` only being Y2038-safe on 64-bit

This updates gdbus-codegen.xml to include documentation for the
--symbol-decorator, --symbol-decorator-header and
--symbol-decorator-define options, which is used to help to export
symbols in the generated code.
gtk-doc 1.33 hasn’t been released yet, but when it is, it’ll contain
three fixes which are necessary for correctly detecting which symbols
are undocumented/undeclared/unused in GLib:
• gtk-doc@b866a90b
• gtk-doc@ca42972c
• gtk-doc@b922e148
1.32.1 is the development version number which will eventually be
released as 1.33.
Until then, we can’t run the gtk-doc tests in CI because they reliably
fail spuriously. See !1488.

This adds support to be able to explicitely stored interned strings into
G_TYPE_STRING GValue.
This is useful for cases where the user:
* *knows* the string to be stored in the GValue is canonical
* Wants to know whther the string stored is canonical
This allows:
* zero-cost GValue copy (the content is guaranteed to be unique and exist
throughout the process life)
* zero-cost string equality checks (if both string GValue are interned, you just
need to check the pointers for equality or not, instead of doing a strcmp).

This reverts commit c0146be3a4.
The revert was originally added because the original change broke
gnome-build-meta. Now that the problem has been diagnosed, the original
commit can be fixed — see the commit which follows this one.

The glib-mkenums program allows generating code to handle enums/flags
with very different purposes. One of its purposes could be generating
per-enum/flag methods to be exposed in a library API, and while doing
that, it would be nice to have a way to specify in which API version
the enum/flag was introduced, so that the same version could be shown
in the generated API methods.
E.g. From the following code:
/**
* QmiWmsMessageProtocol:
* @QMI_WMS_MESSAGE_PROTOCOL_CDMA: CDMA.
* @QMI_WMS_MESSAGE_PROTOCOL_WCDMA: WCDMA.
*
* Type of message protocol.
*
* Since: 1.0
*/
typedef enum { /*< since=1.0 >*/
QMI_WMS_MESSAGE_PROTOCOL_CDMA = 0x00,
QMI_WMS_MESSAGE_PROTOCOL_WCDMA = 0x01
} QmiWmsMessageProtocol;
The template would allow us to generate a method documented like this,
including the Since tag with the value given in the mkenums 'since' tag.
/**
* qmi_wms_message_protocol_get_string:
* @val: a QmiWmsMessageProtocol.
*
* Gets the nickname string for the #QmiWmsMessageProtocol specified at @val.
*
* Returns: (transfer none): a string with the nickname, or %NULL if not found. Do not free the returned value.
* Since: 1.0
*/
const gchar *qmi_wms_message_protocol_get_string (QmiWmsMessageProtocol val);

The public functions exposed as static inlines currently don't have
annotations to describe when they were introduced. This means that
compiling this file:
#include <glib.h>
void foo (void)
{
g_rec_mutex_locker_new (NULL);
}
with:
gcc -c test.c \
-I/tmp/glib/include/glib-2.0 \
-I/tmp/glib/lib/x86_64-linux-gnu/glib-2.0/include \
-Werror \
-DGLIB_VERSION_MAX_ALLOWED=GLIB_VERSION_2_28 \
-DGLIB_VERSION_MIN_REQUIRED=GLIB_VERSION_2_28
will not produce any error message, despite using
`g_rec_mutex_locker_new`, a function that was introduced after 2.28.
This patch adds some annotations to all the publicly exposed static
inline functions I could find.
I could not use the existing G_AVAILABLE* macros, because they may
expand to `extern`. This would then clash with the `static` keyword and
produce:
../glib/gthread.h:397:1: error: multiple storage classes in declaration specifiers
397 | static inline GRecMutexLocker *
| ^~~~~~
So I opted for adding a new set of macros,
GLIB_AVAILABLE_STATIC_INLINE_IN_2_XY.
With this patch applied, the example from above produces the expected
warning:
test.c: In function ‘foo’:
test.c:5:3: error: ‘g_rec_mutex_locker_new’ is deprecated: Not available before 2.60 [-Werror=deprecated-declarations]

In cases where performance are critical it can be useful to disable
checks and asserts. GStreamer has those options too, using the same name
and setting them yielding means we can set those options on the main
project (e.g. gst-build) and glib will inherit the same value when built
as subproject.
New features were added for gio tool, but they are not mentioned in
man pages as it is not generated from GOptionEntry in contrast to the
help output. Let's update the man pages to reflect the recent changes.
Skip the gdbus-object-manager-example which is generated as part of
testing.

This is for use in testing POSIX-style functions like `rmdir()`, which

`errno`.
The new macro prints `errno` and `g_strerror (errno)` on failure.

Making this validation code public allows projects to validate a
GParamSpec name before creating it. While hard-coded GParamSpec don't
need this, we can't afford crashing the main program for dynamically
generated GParamSpec from user-created data.
In such case, we will need to validate the param names and return errors
instead of trying to create a GParamSpec with invalid names.
Includes modifications from Philip Withnall and Emmanuele Bassi to
rearrange the new function addition and split it into one function for
GParamSpecs and one for GSignals.
We're using Meson for GLib itself, and we recommend people to use it

The relevant parts of the generated example documentation are already
`xi:include`d into the `migrating-gdbus.xml` page, so are turned into
HTML there. Installing them separately means they also get installed
into `/usr/share/gtk-doc/html/gdbus-object-manager-example/`, which
seems redundant.

This reverts commit b6d8efbebc.
This GLib API is good, but the implentation is not ready, so there's no
reason to commit to the API in GLib 2.64. We can reland again when the
implementation is ready.
There are three problems: (a) The glib-networking implementation normally
works, but the test has been broken for a long time. I'm not comfortable
with adding a major new feature without a working test. This is
glib-networking#104. (b) The WebKit implementation never landed. There
is a working patch, but it hasn't been accepted upstream yet. This API
isn't needed in GLib until WebKit is ready to start using it.
https://bugs.webkit.org/show_bug.cgi?id=200805. (c) Similarly, even if
the WebKit API was ready, that itself isn't useful until an application
is ready to start using it, and the Epiphany level work never happened.
Let's try again for GLib 2.66. Reverting this commit now just means we
gain another six months before committing to the API forever. No reason
to keep this in GLib 2.64 when nothing is using it yet.
Now that we require Meson 0.52 to build the doc, we can also pull
gtk-doc as subproject when missing from the system. This requires
to pull gtk-doc master because needed changes there haven't been release
yet.
This has the side effect of always rebuilding the doc at each build when
gtk_doc option is enabled (not by default). Most importantly, this will
enable doc check on our CI.
