775014dd3b gfile: Use a more specific error message if symlinks are not supported
The string is already translated in `GLocalFile`, so this doesn’t
introduce a new translatable string.

53f6ede628 gfile: Don’t copy files as private if using default permissions
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.

f17055f593 gfile: Do not follow symlinks when moving
It is expected that `g_file_move()` moves symlink file itself, not its
target. Unfortunately, copy and delete fallback passes `GFileCopyFlags`
and don't explicitly use `G_FILE_COPY_NOFOLLOW_SYMLINKS`. This may cause
that symlink target is copied and symlink itself is removed. Let's
explicitly pass `G_FILE_COPY_NOFOLLOW_SYMLINKS` to the copy operation to
prevent this unexpected behavior.

6694172014 gfile: Remove G_FILE_COPY_NOFOLLOW_SYMLINKS from g_file_move() docs
The `G_FILE_COPY_NOFOLLOW_SYMLINKS` flag doesn't make sense for move operation,
neither local implementation doesn't handle this flag in any way. Therefore
this paragraph should be removed from the docs (it was probably copy&pasted
from `g_file_copy()` docs by mistake).

d8f8f4d637 gfile: Limit access to files when copying
file_copy_fallback creates new files with default permissions and
set the correct permissions after the operation is finished. This
might cause that the files can be accessible by more users during
the operation than expected. Use G_FILE_CREATE_PRIVATE for the new
files to limit access to those files.

cec5778cad gappinfo: Add launch_uris_async() and launch_uris_finish() vfuncs
The g_app_info_launch_uris_async() and g_app_info_launch_uris_finish()
functions are crucial to fix g_app_info_launch_default_for_uri_async()
to be really asynchronous.

This patch also adds GDesktopAppInfo implementation of that vfuncs.

4808a957b5 GFile: Add g_file_peek_path()
This is a variant of g_file_get_path() which returns a const string to
the caller, rather than transferring ownership.

I've been carrying `gs_file_get_path_cached()` in libgsystem and it
has seen a lot of use in the ostree and flatpak codebases.  There are
probably others too.

I think language bindings like Python/Gjs could also use this to avoid
an extra malloc (i.e. we could transparently replace
`g_file_get_path()` with `g_file_peek_path()`.

(Originally by Colin Walters. Tweaked by Philip Withnall to update to
2.56, change the function name and drop the locking.)

5cddde1fb2 Consistently save errno immediately after the operation setting it
Prevent the situation where errno is set by function A, then function B
is called (which is typically _(), but could be anything else) and it
overwrites errno, then errno is checked by the caller.

errno is a horrific API, and we need to be careful to save its value as
soon as a function call (which might set it) returns. i.e. Follow the
pattern:
  int errsv, ret;
  ret = some_call_which_might_set_errno ();
  errsv = errno;

  if (ret < 0)
    puts (strerror (errsv));

This patch implements that pattern throughout GLib. There might be a few
places in the test code which still use errno directly. They should be
ported as necessary. It doesn’t modify all the call sites like this:
  if (some_call_which_might_set_errno () && errno == ESOMETHING)
since the refactoring involved is probably more harmful than beneficial
there. It does, however, refactor other call sites regardless of whether
they were originally buggy.

60a6ae6f0b Fix GError leak in g_file_query_writable_namespaces()
gvfs commit b358ca "Make sure metadata is always returned by
query_writable_namespaces()" changed the
query_writable_namespaces vfunc to never return NULL, but the error
checking in g_daemon_file_query_writable_namespaces still assumes vfunc
failure implies NULL return value and GError set. This causes a memory
leak as on failure the GError will be set but the vfunc implementation
will have created its own default list so NULL will not be returned, and
the GError will never be cleared.

This commit directly checks if the GError is set to detect failures,
my_error is directly dereferenced in the error block anyway.

This also removes an unneeded call to g_file_attribute_info_new(); as
the vfunc always returns us a non-NULL GFileAttributeInfoList.

Assume unix platforms support the original POSIX.1 standard.
Specifically, assume that if G_OS_UNIX, then we have chown(),
getcwd(), getgrgid(), getpwuid(), link(), <grp.h>, <pwd.h>,
<sys/types.h>, <sys/uio.h>, <sys/wait.h>, and <unistd.h>.

Additionally, since all versions of Windows that we care about also
have <sys/types.h>, we can remove HAVE_SYS_TYPES_H checks everywhere.

Also remove one include of <sys/times.h>, and the corresponding
configure check, since the include is not currently needed (and may
always have just been a typo for <sys/time.h>).

be2656f139 g_file_copy: Fall back to pathname queryinfo to help gvfs backends
It's not difficult to do; not all backends implement it, and for some
it may be difficult to implement query_info_on_read(), so let's just
do both.

dbf95a5ae9 measure_disk_usage: skip progress on NULL callback
In the real_..._async wrapper for GFile.measure_disk_usage, skip the
wrapping of the progress callback in the case that the user gave a NULL
callback to the async function.  This is a performance improvement
because the sync version won't have to do continuous sampling of the
clock to issue a call to the wrapper which will then do nothing.

Unfortunately, I made this simplifying assumption when writing the
wrapper, but forgot to actually implement it when making the sync call.
As a result, the wrapper is still called, and invokes the NULL callback,
causing a segfault.

Make sure we pass NULL if the user's callback was NULL.

9f1a0b57cd Ensure g_file_copy() does not temporarily expose private files
Previously, g_file_copy() would (on Unix) create files with the
default mode of 644.  For applications which might at user request
copy arbitrary private files such as ~/.ssh or /etc/shadow, a
world-readable copy would be temporarily exposed.

This patch is suboptimal in that it *only* fixes g_file_copy()
for the case where both source and destination are instances of
GLocalFile on Unix.

The reason for this is that the public GFile APIs for creating files
allow very limited control over the access permissions for the created
file; one can either say a file is "private" or not.  Fixing
this by adding e.g. g_file_create_with_attributes() would make sense,
except this would entail 8 new API calls for all the variants of
_create(), _create_async(), _replace(), _replace_async(),
_create_readwrite(), _create_readwrite_async(), _replace_readwrite(),
_replace_readwrite_async().  That can be done as a separate patch
later.

02aaef5a4d g_file_copy(): Clean up logic for info query
Previously, we called g_file_query_info() *again* on the source at the
very end of the copy.  This has the lame semantics that if the source
happened to be deleted, we would fail to apply attributes to the
destination.  This could even be a security flaw.

This commit changes things so that we query info from the source
*stream* after opening - i.e. on Unix we use the proper fstat() and
friends.  That way we operate more atomically.

bd57c3f171 GFile: fix the *_async_thread()
In the *_async_thread() functions, call the corresponding synchronous
function instead of calling the interface vfunc, which can be NULL.

In some cases the check for the vfunc == NULL was done, but to be
consistent it is better to always call the synchronous version (and the
code is simpler).

978571d854 g_file_copy(): Ensure G_FILE_COPY_OVERWRITE preserves permissions
We need to close the stream *before* applying the file modes, because
g_file_replace() allocates a temporary file.  At the moment we're
applying the modes to the extant file, then immediately rename()ing
over it with the default perms.

This regressed with commit 166766a89f.

The real fix here is to have g_file_create_with_info() so that we can
atomically create a file with the permissions we want.

f398bec5bc Add g_close(), use it
There are two benefits to this:

1) We can centralize any operating system specific knowledge of
   close-vs-EINTR handling.  For example, while on Linux we should never
   retry, if someone cared enough later about HP-UX, they could come by
   and change this one spot.
2) For places that do care about the return value and want to provide
   the caller with a GError, this function makes it convenient to do so.

Note that gspawn.c had an incorrect EINTR loop-retry around close().

e908b50371 gfile: don't report completion twice on g_file_load_contents error
When an error occurs while reading the file input stream in
g_file_load_contents (e.g. because the operation was cancelled), the
code is correctly calling g_task_return_error(), but in the callback
from the close operation, g_task_return_boolean() will be called again.

Code that cleans up its state in the async callback will then be called
twice, leading to invalid memory access.

5eba978497 GFile: Add Btrfs clone ioctl support
The attached patch adds support for the btrfs "clone" ioctl which
makes Copy-on-Write reflinks, resulting in cheap O(1) copies when
source/destination are on the same filesystem. The ioctl itself is
quite straightforward, and GNU coreutils has had support since 7.5
(--reflink=auto --sparse=auto).

The ioctl only operates on regular files and symlinks, and always
follows symlinks; checks have been added accordingly.

This patch would be very useful for everyone who uses btrfs
filesystems (Meego folks for instance). On systems that don't have
btrfs, or if the the source is not on a btrfs filesystem, the ioctl
returns EINVAL, and the fallback code is triggered. Hence this will
cause no problems for non-btrfs users.
