Otherwise we’ll end up using the host’s `objcopy`, which will output
object files in the wrong format.

Previously we were keeping a pointer to the `GFileMonitor` in a
`GFileMonitorSource` instance, but since we weren’t keeping a strong
reference, that `GFileMonitor` instance could be finalised from another
thread at any point while the source was referring to it. Not good.
Use a weak reference, and upgrade it to a strong reference whenever the
`GFileMonitorSource` is referring to the file monitor.

It’s not enough to unref the monitor, since the GLib worker thread might
still hold a reference to it.

Helps: #1903
`DesktopFileDir` pointers are passed around between threads: they are
initially created on the main thread, but a pointer to them is passed to
the GLib worker thread in the file monitor callback
(`desktop_file_dir_changed()`).
Accordingly, the `DesktopFileDir` objects either have to be
(1) immutable;
(2) reference counted; or
(3) synchronised between the two threads
to avoid one of them being used by one thread after being freed on
another. Option (1) changed with commit 99bc33b6 and is no longer an
option. Option (3) would mean blocking the main thread on the worker
thread, which would be hard to achieve and is against the point of
having a worker thread. So that leaves option (2), which is implemented
here.

Fixes: #1903
When the _g_dbus_worker_flush_sync() schedules the 'data' and releases
the worker->write_lock, it is possible for the GDBus worker thread thread
to finish the D-Bus call and acquire the worker->write_lock before
the _g_dbus_worker_flush_sync() re-acquires it in the if (data != NULL) body.
When that happens, the ostream_flush_cb() increases the worker->write_num_messages_flushed
and then releases the worker->write_lock. The write lock is reacquired by
the _g_dbus_worker_flush_sync(), which sees that the while condition is satisfied,
thus it doesn't enter the loop body and immediately clears the data members and
frees the data structure itself. The ostream_flush_cb() is still ongoing, possibly
inside flush_data_list_complete(), where it accesses the FlushData, which can be
in any stage of being freed.
Instead, add an explicit boolean flag indicating when the flush is truly finished.

Mounts are currently completed only if the prefix looks like scheme,
however, this doesn't work well if the mounts have also path component.
Let's always include them to fix this issue. The mounts are cached by the
volume monitors, so it should not significantly affect the performance.
Currently, "gio mount google-drive<tab>" isn't completed even though
that volume exists for google-drive://oholy@redhat.com/. Let's use
"gio mount -li" output to complete also activation roots of volumes.
Currently, "gio list file:///h<tab>" doesn't complete "file:///home"
because the result of "dirname file:///h" is not "file:///" but "file:/",
which breaks the consequent logic. Let's subtract basename from the
path in order to workaround this issue.

g_date_time_add_seconds() and g_date_time_add_full() use floating-point
seconds, which can result in the value varying slightly from what's
actually on disk. This causes intermittent test failures in
gio/tests/g-file-info.c on Debian i386, where we set a file's mtime
to be 50µs later, then read it back and sometimes find that it is only
49µs later than the previous value.
I've only seen this happen on i386, which means it might be to do with
different floating-point rounding when a value is stored in the 80-bit
legacy floating point registers rather than in double precision.
g_date_time_add() takes a GTimeSpan, which is in microseconds;
conveniently, that's exactly what we get from the GFileInfo.

If we're cross-compiling, the installed-tests are useful even if we
can't run them on the build machine: we can copy them to the host
machine (possibly via a distro package like Debian's libglib2.0-tests)
and run them there.
While I'm changing the build-tests condition anyway, deduplicate it.
Based on a patch by Helmut Grohne.

Skip it on systems which don’t support it, rather than compiling it out.
That gives us more information from test runs about which tests are

As with the previous commit, `st_mode` contains both the file type
(regular file, directory, symlink, special, etc.) and the file mode. For
`G_FILE_ATTRIBUTE_ID_UNIX_MODE`, we only want the file mode — so mask
`st_mode` with `~S_IFMT`.
Signed-off-by: Philip Withnall <withnall@endlessm.com>
chmod() technically only accepts file modes, not the file type and mode
as returned by stat(). Filter by `S_IFMT` to avoid sending the file
type (regular file, directory, symbolic link, etc.).
In practice, chmod() ignores anything except the file mode, but we might
as well comply with the specification.

`GFile` always checks whether these vfuncs are `NULL` before calling
them, so document that it’s safe for implementations of `GFile` to not
implement them.
Signed-off-by: Philip Withnall <withnall@endlessm.com>
The caller assumes that an unimplemented vfunc means that copying is
unsupported (and falls back to its internal copy implementation), so
there’s no point in implementing the vfunc just to unconditionally
return `G_IO_ERROR_NOT_SUPPORTED`.
Signed-off-by: Philip Withnall <withnall@endlessm.com>
Rather than defining a vfunc which only ever returns
`G_IO_ERROR_NOT_SUPPORTED`, just don’t define the vfunc at all. The
caller in `GFile` interprets this as symlinks not being supported — so
we get the same behaviour, but without spending a vfunc call on it.

If a copy operation is started with `G_FILE_COPY_TARGET_DEFAULT_PERMS`,
don’t create the destination file as private. Instead, create it with
