g_task_set_name() was added in GLib 2.60, so only use it in the
overridden definition of g_task_set_source_tag() if the user has said
that they require GLib ≥ 2.60.
This is a follow up to commit b08bd04abe.

There is no guarantee that this function would not be called
concurrently. Particularly since flatpak_info_read was set to TRUE
before /.flatpak-info is actually read from disk, there is a potential
race where a second thread would return default values for the various
flags set from that file.
Fixes#2159
Correct an off-by-one error in hex_unescape_string()'s computation of
the output string length.
(Turned into a git-format patch by Philip Withnall. Original patch
submitted on the Debian bug tracker, bug#962912.)
It's safe to assume an escaped string doesn't contain embedded null bytes,
but raw memory buffers (as returned by getxattr()) require more care.
If the length of the data to be escaped is known, use that knowledge instead
of invoking strlen().
(Turned into a git-format patch by Philip Withnall. One minor formatting
tweak. Original patch submitted on the Debian bug tracker, bug#962912.)
Fixes: #422
And improve them externally, where not otherwise set, by setting them
from the function name passed to `g_task_set_source_tag()`, if called by
third party code.
This should make profiling and debug output from GLib more useful.

`complete_in_idle_cb()` shows up in a lot of sysprof traces, so it’s
quite useful to include the most specific contextual information we can
in it.

When an app is spawned using g_desktop_app_info_launch_uris_with_spawn
it will expand the various token in the app's commandline with the
URIs of the files to open. The expand_macro() function that is used for
this advances the pointer to the URI list to show up to which entries
it used.
To not loose the pointer to the list head a duplicate of the URI list
was actually passed to expand_macro(). However, it's not necessary to
create a copy of the URI list for that as expand_macro() will only
change which element the pointer will point to.
This behaviour actually caused the duplicated list to be leaked as the
the list pointer is NULL once all URIs are used up by expand_macro()
and thus nothing was freed at the end of the function.
In ostree based systems, such as flatpak and fedora silverblue, the
time of modification of every system file is epoch 0, including
giomodule.cache, which means that every module is loaded and unloaded
every time.
The solution is to use the change time of the file as well. In a typical
system, it is equal to the mtime, and in an ostree based system, since
the directory is mounted as read-only, the user cannot add a module and
we must assume that the cache file corresponds to the modules.

This speeds up the `cancellable` test a little by stopping waiting for
the threads to start up as soon as they have started, rather than after
an arbitrary timeout.

This should fix some sporadic test failures in this test, although I
can’t be sure as I was unable to reproduce the original failure.

Closes: #1764
It seems that allowing the GCancellable to be finalised in either the
main thread or the worker thread sometimes leads to crashes when running
on CI.
I cannot reproduce these crashes locally, and various analyses with
memcheck, drd and helgrind have failed to give any clues.
Fix this for this particular test case by deferring destruction of the
`GCancellable` instances until after the worker thread has joined.
That’s OK because this test is specifically checking a race between
`g_cancellable_cancel()` and disposal of a `GCancellableSource`.
The underlying bug remains unfixed, though, and I can only hope that we
eventually find a reliable way of reproducing it so it can be analysed
and fixed.

The G_FILE_ATTRIBUTE_FILESYSTEM_REMOTE is set to TRUE only for NFS
filesystem types currently. Let's add also SMB filesystem types. This
also changes g_local_file_is_nfs_home function logic to handle only
NFS filesystems.
The g_local_file_is_remote function is misleading as it works only for
NFS filesystem types and only for locations in home directorly. Let's
rename it to g_local_file_is_nfs_home to make it obvious.
statfs/statvfs is called several times when querying filesystem info.
This is because the G_FILE_ATTRIBUTE_FILESYSTEM_REMOTE attribute is set
over is_remote_fs function, which calls statfs/statvfs again. Let's use
the already known fstype instead of redundant statfs/statvfs calls.
This also changes g_local_file_is_remote implementation to use
g_local_file_query_filesystem_info to obtain fstype, which allows to
remove duplicated code from is_remote_fs function.
The G_FILE_ATTRIBUTE_FILESYSTEM_REMOTE currently works only for locations
in the home directory. Let's make it work also for files outside the home
directory.
There are glocalfile.h and glocalfileprivate.h header files currently.
None of those header files is public, so it doesn't make sense to have
two private headers for glocalfile.c. Let's remove glocalfileprivate.h.
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!

In glib-networking#127, it was reported that we don't properly implement
the documented behavior of these properties. However, we cannot fix it
because libsoup relies on the implemented behavior, and it's hard to
change that without cascading breakage. The practical solution is to
adjust our documentation to match reality. There should be no downsides
to this, and compat risk of changing the documentation is much smaller
than risk of changing the implementation, so I think this is the best we
can make of an unfortunate situation. See glib-networking#127 for full
discussion and glib-networking#129 for the regression when we attempted
to match the documented behavior.
Some editors automatically remove trailing blank lines, or
automatically add a trailing newline to avoid having a trailing
non-blank line that is not terminated by a newline. To avoid unrelated
whitespace changes when users of such editors contribute to GLib,
let's pre-emptively normalize all files.
Unlike more intrusive whitespace normalization like removing trailing
whitespace from each line, this seems unlikely to cause significant
issues with cherry-picking changes to stable branches.

While these assertions look right at the first glance,
they actually crash the program. That's because GObject
insists on initializing all construct-only properties
to their default values, which results in
g_win32_registry_key_set_property() being called multiple
times with NULL string, once for each unset property.
If "path" is actually set by the caller, a subsequent
call to set "path-utf16" to NULL will fail an assertion,
since absolute_path is already non-NULL.
With assertions moved the set-to-NULL calls bail out before
an assertion is made.
This ensures that we do really export the symbols for Visual
Studio-style builds, by using _GLIB_EXTERN to decorate the generated
prototypes and including config.h so that we are sure the symbols are
actually exported.
This adds three options to gdbus-codegen so that we may be able to
use a self-defined symbol decorator, such as _GLIB_EXTERN, to decorate
the generated prototypes, to be used possibly to export the symbols, if
needed.
The other two options allows including headers that are required for the
specified symbol decorator to be usable and preprocessor macros that are
required for the symbol decorator to be defined appropriately, also when
needed.
Have the generated .c code decorate the prototypes with "G_MODULE_EXPORT"
instead of "extern" when --internal is not being used, so that we also
export the symbols from the generated code on Visual Studio-style
compilers. If --internal is used, we decorate the prototypes with
"G_GNUC_INTERNAL", as we did before.
Note that since the generated .c code does not attempt to include the
generated headers (if one is also generated), the gnerated headers are
still generated as they were before.
Sometimes this test was timing out due to the file monitor notifications
taking longer than the arbitrary 2s delay before ending the test and
checking its results at the end of `iclosed_cb()`.
Avoid that timing-dependence by ending the test when the expected file
monitor notifications are seen, or after a 10s timeout (if so, the test
is failed).
This makes the test run 4× faster in the normal case, as it’s no longer
waiting for a timeout to elapse if the file monitor notifications come
in sooner.

The test added for #1841 spawned 100000 threads. That was fine on a
desktop machine, but on a heavily loaded CI machine, it could result in
large (and unpredictable) slowdowns, resulting in the test taking over
120s in about 1 in 5 runs, and hence failing that CI pipeline due to a
timeout. When passing normally on CI, the test would take around 90s.
Here’s a histogram of time per iteration on a failing (timed out) test
run. Each iteration is one thread spawn:
Iteration duration (µs) | Frequency
------------------------+----------
≤100 | 0
100–200 | 30257
200–400 | 13696
400–800 | 1046
800–1000 | 123

There’s no actual need for the test to spawn 100000 threads, so rewrite
it to reuse a single thread, and pass new data to that thread.
Reverting the original commit (e4a690f5dd) reproduces the failure on
100 out of 100 test runs with this commit applied, so the test still
works.
The test now takes 3s, rather than 11s, to run on my computer, and has
passed when run with `meson test --repeat 1000 cancellable`.

An extra argument to g_win32_registry_key_get_value_w() and
g_win32_registry_key_get_value() indicates that RegLoadMUIStringW()
should be used instead of RegQueryValueExW(). It only works on
strings, and automatically resolves resource strings (the ones
that start with "@").
The extra argument is needed to find resource DLLs that are only
specified by their relative name.
