Casting pointer types around is a bit fiddly when you also end up
dereferencing them. Take advantage of the fact that the
`__atomic_load()` and `__atomic_store()` built-ins are polymorphic, and
use `__typeof__()` to ensure that the atomic pointer macros use the
caller-provided types internally, and hence any type mismatches are
entirely the caller’s fault rather than ours.
This also means that the `__atomic_{load,store}()` built-ins have the
right alignment and width data from the caller-provided types, in case
that’s needed.

Various places that used atomic functions were using the wrong return
type. Fix that. This introduces no functional changes.

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.
Fixes build failure:

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
being run on which architectures.

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.

The string is already translated in `GLocalFile`, so this doesn’t
introduce a new translatable string.

This sets the `G_FILE_COPY_DEFAULT_PERMS` flag on the operation,
creating the copied file with default permissions rather than the same
permissions as the source file.

Fixes: #174
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
the process’ current umask (i.e. ‘default permissions’).
This is a partial re-work of commit d8f8f4d637, with
input from Ondrej Holy.
