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`.

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.

We already depend on Meson 0.49.2, which depends on Python 3.5, so we’ve
actually implicitly had this requirement for a while. Might as well make
it explicit.

The actual parameter name in g_file_attribute_matcher_new()
attributes, so change the param reference to match. This way,
doc tools can create a proper link.
`man dup2` says that on Linux, dup2() can return `EBUSY` if the
operation needs to be retried (in addition to returning `EINTR` in other
cases where it needs to be retried).

All uses of fdwalk in gspawn are between fork and exec, which means only
async-signal safe functions can be called if the parent process has
multiple threads. Since fdwalk is not a standard API, we should not
assume it is safe to use unless the manual of the system explicitly says
it is async-signal safe.

"glib-2.0 G_CONST_RETURN causing GCC 'warning: const' on F31", where the GCC
diagnostic
> test.c:2:13: warning: const

had confused me, and "Deprecated pre-processor symbol, repace with const" is
probably a better warning message than just "const".
(That recent GCC only prints "Deprecated pre-processor symbol, repace with "
appears to be a bug in GCC that GLIB_UNAVAILABLE_MACRO already suffers from,
too. Recent Clang correctly prints "Deprecated pre-processor symbol, repace
with const".)

g_file_info_set_modification_time() and
g_file_info_set_modification_date_time() set the
G_FILE_ATTRIBUTE_TIME_MODIFIED_USEC attribute in addition to
G_FILE_ATTRIBUTE_TIME_MODIFIED, so microsecond precision is available
when provided by the caller, so mention both attributes in the docs.
