is working to call vanished handler in the thread which had watched the name
2) Check cancellation of vanished handler if the name is unwatched before
vanished callback is dispatched.

After the recent reworking of this code it was possible for `g_close()`
to be called on `fd == -1`, which is invalid. It would have reported an
error, were errors not ignored. So it was harmless, but still best to
fix.
Simplify the error handling by combining both error labels and checking
the state of `fd` dynamically.

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.

In the 2.68 cycle we’d added 3 new enumerator elements. Due to the
preceding commit, they can now be annotated with
`GLIB_AVAILABLE_ENUMERATOR_IN_2_68`, which will make it a bit easier for
third party projects to notice when they’re using these symbols without
having bumped their GLib dependency.

`""` is not a valid path (`stat()` on it returns `ENOENT`). Previously,
a full `GLocalFile` was being created, which ended up resolving to
`$CWD`, through path canonicalisation. That isn’t right.
Fix it by creating a `GDummyFile` instead, and adding a unit test.

Calling `dlopen()` with `libutil.so` makes the installed tests depend on
having glibc's development files installed. To avoid this, we can work
out the runtime library name at build time and `dlopen` that instead.
This approach is [taken from libfprint][1], thanks to Marco Trevisan.

`ENXIO` can be returned from `open(2)` for special files (FIFOs, device
files and domain sockets) which are not backed by anything.
This fixes the error returned by `g_file_replace()` when trying to
replace such a file, so that it now matches the documentation.

These test all the functionality and combinations of flags I can think
of. They do not cover dynamic behaviour (for example, what would happen
if the source file is deleted by another process part-way through a call
to `g_file_replace()`).

The `G_FILE_CREATE_REPLACE_DESTINATION` flag is equivalent to unlinking
the destination file and re-creating it from scratch. That did
previously work, but in the process the code would call `open(O_CREAT)`
on the file. If the file was a dangling symlink, this would create the
destination file (empty). That’s not an intended side-effect, and has
security implications if the symlink is controlled by a lower-privileged
process.
Fix that by not opening the destination file if it’s a symlink, and
adjusting the rest of the code to cope with
- the fact that `fd == -1` is not an error iff `is_symlink` is true,
- and that `original_stat` will contain the `lstat()` results for the
symlink now, rather than the `stat()` results for its target (again,
iff `is_symlink` is true).
This means that the target of the dangling symlink is no longer created,
which was the bug. The symlink itself continues to be replaced (as
before) with the new file — this is the intended behaviour of
`g_file_replace()`.
The behaviour for non-symlink cases, or cases where the symlink was not
dangling, should be unchanged.
Includes a unit test.

When GLib code is checked out with Windows line endings (happens on Windows),
data-to-c.py embedded that line endings into generated string literal. And
then they translated to double newlines in glib-compile-resources output.
clang-cl failed to compile such files because of empty lines in the middle of
multiline macros:
#define G_MSVC_CTOR(_func,_sym_prefix) \
static void _func(void); \
To fix the issue, enable 'universal newlines' mode when reading the input in
data-to-c.py - translate both '\n' and '\r\n' to '\n'.

This will require distributions to ensure they pass
`--localstatedir=/var` correctly to Meson, but they should be doing that
already.
See https://mesonbuild.com/Builtin-options.html#directories for details
about how Meson treats `localstatedir` differently from most other `dir`
variables.

It’s unlikely that the machine ID will be invalid (it’s system
configuration), but it would be helpful to not propagate invalid IDs
further, since a lot of things rely on it.
It’s not easy to test this (it requires factoring out the code so it can
be used from a test program, or allowing it to load a machine ID from a
custom path), so I haven’t added unit tests. I’ve tested manually by
overriding the loaded machine ID.

For non-Linux UNIX systems, the label 'close_libutil:' in
'test_pollable_unix_pty()' will have no statement that goes with that
label. Just do a 'return' on non-Linux UNIX systems.
File monitor creation may fail. We should check for this, rather than
ignoring it and then spewing criticals upon improperly assuming that we
have a valid GFileMonitor rather than NULL.
In practice, creating the GFileMonitors here fail when opening a large
number of tabs in Epiphany. I'm still investigating to see why, but it
doesn't matter for the purposes of this commit.
Expand an existing unit test to check that the target FD of a
`g_subprocess_launcher_take_fd()` call doesn’t get closed when
`g_subprocess_launcher_close()` is called. Only the source FD should be
closed by the parent process.

This is a regression introduced in commit 67a589e505. Previously, the
source/target FD pairs were stored in `needdup_fd_assignments`, in
consecutive entries, so source FDs had even indices and target FDs had
odd indices.
I didn’t notice that the array index was being incremented by 2 when
closing FDs, when porting from the old code. So previously the code was
only closing the source FDs; after the port, it was closing source and
target FDs.
That’s incorrect, as the target FDs are just integers in the parent
process. It’s only in the child process where they are actually FDs —
and `g_subprocess_launcher_close()` is never called in the child
process.
This resulted in some strange misbehaviours in any process which used
`g_subprocess_launcher_take_fd()` with target FDs which could have
possibly aliased with other FDs in the parent process (and which weren’t
equal to their mapped source FDs).
Thanks to Olivier Fourdan for the detailed bug report.

This was correctly annotated for proper return values but in case of out
parameters it was only annotated as (optional) and not additionally as
(nullable).
This improves performance by eliminating the use of a
`GSpawnChildSetupFunc` in the common case (since that setup code has now
moved into `g_spawn*()` itself), and enables the use of the fix to avoid
the child error reporting FD being overwritten by target FD mappings,
introduced via `g_spawn_async_with_pipes_and_fds()`.
It reworks how the source/target FD mapping is stored within
`GSubprocessLauncher` to match what `g_spawn*()` uses. The two
approaches are equivalent.
