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.

Add a new GFileMonitorFlag: G_FILE_MONITOR_WATCH_HARD_LINKS. When set,
changes made to the file via another hard link will be detected.
Implement the new flag for the inotify backend.

Add a pair of new APIs: one to GFile to create a new file from a
commandline arg relative to a given cwd and one to
GApplicationCommandLine to create a GFile from an arg, relative to the
cwd of the invoking commandline.

Reimplement gioscheduler in terms of GTask, and deprecate the original
gioscheduler methods. Update docs to point people to GTask rather than
gioscheduler and GSimpleAsyncResult, but don't actually formally
deprecate GSimpleAsyncResult yet.

When creating a directory fails for some reason other than
the parent not existing, don't clear the error before we try
to propagate it.
To reproduce, run 'ostadmin init' on /ostree or otherwise try to
run the function on a directory with a parent directory where the
current user is not allowed to write.

This looks like it was stubbed out but not implemented; the vtable
entry dates to commit 3781343738 which
is just alex's initial merge of gio into glib.
I was working on some code that wants an asynchronous rm -rf
equivalent, and so yeah, this is desirable.

Finish deprecating the "handle GSimpleAsyncResult errors in the
wrapper function" idiom (and protect against future GSimpleAsyncResult
deprecation warnings) by adding a "legacy" GAsyncResult method
to do it in those classes/methods where it had been traditionally
done.
(This applies only to wrapper methods; in cases where an _async
vmethod explicitly uses GSimpleAsyncResult, its corresponding _finish
vmethod still uses g_simple_async_result_propagate_error.)
https://bugzilla.gnome.org/show_bug.cgi?id=667375https://bugzilla.gnome.org/show_bug.cgi?id=661767
Originally, the standard idiom with GSimpleAsyncResult was to handle
all errors in the _finish wrapper function, so that vmethods only had
to deal with successful results. But this means that chaining up to a
parent _finish vmethod won't work correctly. Fix this by also checking
for errors in all the relevant vmethods. (We have to redundantly check
in both the vmethod and the wrapper to preserve compatibility.)

The "mainloop_barrier" in copy_async_thread() is unnecessary, since
the g_simple_async_result_complete_in_idle() will be queued after all
of the g_io_scheduler_job_send_to_mainloop_async()s, and sources with
the same priority will run in the order in which they were queued.

The logic here is pretty twisted, but basically we were leaking a ref
for each non-existent parent. The clearest way to fix this was to
move to more explicit refcounting logic; when a variable is pointing
to an object, it holds a ref.

g_file_set_attribute() also permits a NULL value for value_p, and requires it
to be NULL to unset it. Also fix the wrong variable name in the documentation.

g_file_make_directory_with_parents() will fail for already
existing directories, unlike g_mkdir_with_parents(), so mention
this clearly in the docs.

_GNU_SOURCE must be defined before including any other (system)
header, so defining it in glib-unix.h (and hoping no one has included
anything else before that) is wrong. And the "#define _USE_GNU"
workaround for this problem in gnetworkingprivate.h is even wronger
(and still prone to failure anyway due to single-include guards).
Fix this by defining _GNU_SOURCE in config.h when building against
glibc. In theory this is bad because new releases of glibc may include
symbols that conflict with glib symbols, which could then cause
compile failures. However, most people only see new releases of glibc
when they upgrade their distro, at which point they also generally get
new releases of gcc, which have new warnings/errors to clean up
anyway.

Move all the annotations over from gobject-introspection.
They will not be used directly by the introspection scanner for now,
instead they will be extracted by a script and updated manually
until introspection is properly integrated into the glib build
The (linux specific) system call splice can be
used to transfer data between file descriptors
whitout copying them into user space.
See bug #604086 for additional details.
Note: Since we export types with Iface in the name rather than
Interface we have to use some typedefs to make this work. New
interfaces should probably use Interface as the public name.
For details, see bug 587482. The new api:
- Provide new _with_operation() variants of all unmount and eject methods
- Add GMountOperation::show-processes signal
- this can be used to show processes blocking an unmount operation
- Deprecate all unmount and eject methods
- Add g_drive_can_start_degraded() method
- this is to avoid auto-starting degraded drives
- Make g_drive_stop() resp. g_file_stop_mountable() take a GMountOperation
- these ops were recently added and not yet public API so it's fine
to change how they work
- Provide a way to poll mountable files, e.g. g_file_poll_mountable()
- Add some missing file attributes for mountable files
- G_FILE_ATTRIBUTE_MOUNTABLE_UNIX_DEVICE_FILE
- needed for the GDU Nautilus extensions to format a volume
- G_FILE_ATTRIBUTE_MOUNTABLE_CAN_START_DEGRADED:
- mimics g_drive_can_start_degraded()
- G_FILE_ATTRIBUTE_MOUNTABLE_CAN_POLL:
- mimics g_drive_can_poll_for_media()
- G_FILE_ATTRIBUTE_MOUNTABLE_IS_MEDIA_CHECK_AUTOMATIC
- mimics g_drive_is_media_check_automatic()
GFile allows for the possibility that external implementations may not
support thread-default contexts yet, via
g_file_supports_thread_contexts(). GVolumeMonitor is not yet
thread-default-context aware.
Add a test program to verify that basic gio async ops work correctly
in non-default contexts.

Add API for starting/stopping drives. This new API will enable
GVolumeMonitor and GVfs implementations to add support for the
following features
1. Powering down external hard disk enclosures / drives
2. Starting/stopping multi-disk devices (such as RAID/btrfs/ZFS)
3. Connecting/disconnecting iSCSI devices
4. Reacting to the user pressing e.g. the "remove drive" button on
a IBM/Lenovo Ultrabay: http://www.thinkwiki.org/wiki/Ultrabay
See the bug for the corresponding GVfs and Nautilus changes.
The default implementation of g_file_copy() checked the size of the file
to copy to give useful progress updates unconditionally. This can cause
long delays on 1-connection FTP servers while it tries to open a second
connection before it returns EBUSY. This patch makes this query only
happen when we actually send progress updates.
