Finish fixing https://bugzilla.novell.com/show_bug.cgi?id=335411 -
	Nautilus crashes when it gets a "volume-mounted" signal for a
	volume that is already mounted.

* libnautilus-private/nautilus-desktop-link-monitor.c
	(link_corresponds_to_drive): Oops, check that the link_drive is
	not NULL before comparing it.  We may get a NULL link_drive if the
	link corresponds to a volume without a drive (e.g. a network volume).

2007-10-23  Federico Mena Quintero  <federico@novell.com>

* libnautilus-private/nautilus-desktop-link-monitor.c
	(link_corresponds_to_drive): Use gnome_vfs_drive_compare(), not
	pointer equality, to see if drives are the same.  Apparently
	gnome-vfs can feed us with different GnomeVFSDrive* objects that
	really refer to the same drive.
	(find_link_for_volume): Likewise, for volumes.

* libnautilus-private/nautilus-desktop-link.c
	(nautilus_desktop_link_update_from_volume): Likewise.

2007-10-22  Federico Mena Quintero  <federico@novell.com>

* libnautilus-private/nautilus-debug-log.h
	(NAUTILUS_DEBUG_LOG_DRIVES_VOLUMES): Add a "drives-volumes" log domain.

* libnautilus-private/nautilus-desktop-link-monitor.c
	(refresh_volume_links): Log the drives/volumes we find (milestone
	or not milestone depending on whether we are initializing
	Nautilus).
	(create_drive_link): Log when we create a desktop link for a
	drive.
	(create_volume_link): Likewise, for a volume.
	(drive_connected_callback): Log when a drive gets connected (not
	milestone).
	(drive_disconnected_callback): Likewise, when a drive gets disconnected.
	(volume_mounted_callback): Likewise, when a volume gets mounted.
	(volume_unmounted_callback): Likewise, when a volume gets unmounted.

2007-10-22  Federico Mena Quintero  <federico@novell.com>

* libnautilus-private/nautilus-debug-log.h
	(NAUTILUS_DEBUG_LOG_DESKTOP_LINKS): Add a "desktop-links" log
	domain.

* libnautilus-private/nautilus-desktop-link-monitor.c
	(nautilus_desktop_link_monitor_init): Log initialization of the
	desktop link monitor (milestone).
	(create_link_and_add_preference): Log initialization of each link
	type (milestone).
	(update_link_visibility): Log changes in link visibility (non-milestone).

Fix https://bugzilla.novell.com/show_bug.cgi?id=276193, unable
	to right-click after accessing files on CD via GUI. The problem
	was that Nautilus was crashing under some circumstances when
	unmounting/ejecting a CD. It was caused by some of the code
	previously introduced by this patch.

The fix consists of ignoring the desktop link we are currently
	repopulating when scanning the list of desktop links to uniquefy
	the new filename for this link.

* libnautilus-private/nautilus-desktop-link-monitor.[ch]
	(nautilus_desktop_link_monitor_make_filename_unique): Add a
	"skip_link" argument that will make the algorithm skip the
	provided desktop link when considering non-unique filenames.
	(volume_file_name_used): Skip the link passed from caller,
	if any.

Fix https://bugzilla.novell.com/show_bug.cgi?id=215351, the icon
	for a floppy drive disappears after unmounting the floppy.  Also,
	unmounting an NFS volume makes the icon disappear.

Fix the little bug where a recently-unmounted drive still
	shows an "Unmount Volume" menu item.

* libnautilus-private/nautilus-desktop-link-monitor.c
	(drive_has_volumes_apart_from): New function; checks whether a
	drive has any mounted volumes apart from a given one.  We need
	this to check that corresponds to a volume that is being
	unmounted, since within the volume_unmounted callback, the drive
	still thinks it is mounted (as the volume in question has not been
	removed from it yet).
	(should_show_drive): Check whether the drive has any volumes left
	over aside from the volume being unmounted.
	(volume_unmounted_callback): Pass the volume to should_show_drive().

* libnautilus-private/nautilus-desktop-icon-file.c
	(update_info_from_link): If the link acquires a volume, remove the
	drive from the corresponding NautilusFile.  And the converse: if
	the link acquires a drive, remove the volume from the
	corresponding NautilusFile.  Files can have volumes XOR drives, or
	none.  This fixes the bug where you mount a drive, then umount the
	corresponding volume, and the menu on the drive icon still shows
	"unmount volume".

* libnautilus-private/nautilus-desktop-link.c
	(nautilus_desktop_link_update_from_volume): Removed spurious
	comment.

Deal with a race condition when mounting drives.  The callback
	from gnome_vfs_drive_mount() can be called before the
	GnomeVFSVolumeMonitor is notified that the drive is actually
	mounted.

* src/file-manager/fm-directory-view.c (ActivateParameters):
	Replace the "pending_mounts" counter with a list of
	drives_being_mounted.
	(DriveBeingMounted): New struct used as a closure for a drive
	being mounted, or a drive waiting for its corresponding
	NautilusFile to be notified of changes from the volume monitor.
	(cancel_activate): Replace pending_mounts with
	drives_being_mounted.
	(activate_activation_uris_ready_callback): Don't use the
	not_yet_mounted list.  Instead, build the list of
	parameters->drives_being_mounted out of DriveBeingMounted
	structures.  Mount the drives directly here (instead of using
	g_list_foreach()) so that we can pass a DriveBeingMounted closure
	to gnome_vfs_drive_mount().
	(fm_directory_view_activate_files): Replace pending_mounts with
	drives_being_mounted.
	(try_to_finish_drive_activation): New function.  Moved the code to
	finish activation of drives from
	activation_drive_mounted_callback() to here.
	(activation_drive_mounted_callback): This is our "drive was
	mounted" callback, but the GnomeVFSDrive itself may not think that
	it is mounted yet.  This is a race condition where the
	GnomeVFSVolumeMonitor has not been notified yet.  In this case,
	wait until the corresponding NautilusFile changes; we'll check
	again that the drive is mounted in the "changed" callback.
	(activation_file_changed_after_drive_mounted): New callback for
	NautilusFile::changed.  This gets called when a NautilusFile
	changes after a drive was reported as being mounted.  Here, we try
	to finish the drive activation.

2006-10-05  Federico Mena Quintero  <federico@novell.com>

Support displaying drive icons in the desktop, even if the drives
	are not mounted.  Do this only for drives which are supposed to be
	user-visible (i.e. those that do not support media checks and so
	we cannot know when the user inserts media in them).

Also, support drives with multiple partitions, which will lead to
	multiple volumes for the same drive.

To do this, we add several things:

1. The ability for NautilusDesktopLink to represent a drive as
	well as a volume.

2. The ability to "transform" a NautilusDesktopLink which
	represented a drive, into one that represents a volume.  This
	happens when a drive is mounted.

3. Keep the invariant that drives are only displayed if they are
	unmounted and user visible.  If they are mounted, they get
	replaced with volume links.

* libnautilus-private/nautilus-desktop-link-monitor.c (struct
	NautilusDesktopLinkMonitorDetails): Added "connected_id" and
	"disconnected_id" fields for the signal IDs of GnomeVFSDrive.
	(volume_delete_dialog): Added message about not being able to move
	a drive to the trash.  Support drives or volumes.
	(should_show_drive): New utility function.  Drives are shown if
	they are user-visible, they are not mounted, and the preference to
	show desktop volumes is turned on.
	(should_show_volume): New utility function.  Volumes are shown if
	they are user visible and the preference to show desktop volumes
	is turned on.
	(create_drive_link): New utility function; creates a
	NautilusDesktopLink for a GnomeVFSDrive.
	(create_volume_link): Use should_show_volume().
	(link_corresponds_to_drive): New function.  A NautilusDesktopLink
	corresponds to a drive if it represents the drive itself, or if it
	represents a volume relative to that drive.
	(find_unique_link_for_drive): New function.  Returns the
	NautilusDesktopLink in the desktop that corresponds uniquely to a
	given drive; if there is more than one volume link for a drive
	(e.g. a drive with multiple partitions), returns NULL.
	(drive_connected_callback): New callback.  When a drive is
	connected, we create a link for it if appropriate.
	(drive_disconnected_callback): New callback.  When a drive is
	disconnected, we remove all the links that correspond to it:  a
	single drive link for an unmounted drive, or one or more volume
	links for a mounted drive.
	(volume_mounted_callback): If the volume has a drive, and there is
	an existing link for that drive, update the link to represent the
	volume instead.  Otherwise, create volume link as usual.
	(find_link_for_volume): New utility function; returns the link on
	the desktop which corresponds to a particular volume.
	(volume_unmounted_callback): If unmounting a volume would yield a
	drive that is user visible, transform the corresponding link from
	representing the volume, into one that represents the drive.
	Otherwise, remove the link as usual.
	(refresh_volume_links): New function; does the initial population
	of the links for drives and volumes.
	(desktop_volumes_visible_changed): New callback; use
	refresh_volume_links().
	(nautilus_desktop_link_monitor_init): Use refresh_volume_links()
	instead of doing things by hand here.  Also, connect to
	"drive_connected" and "drive_disconnected" on the volume monitor.

* libnautilus-private/nautilus-desktop-icon-file.c
	(update_info_from_link): Accept a drive or a volume, not just
	volumes.

* libnautilus-private/nautilus-desktop-link.h
	(nautilus_desktop_link_new_from_drive_or_volume): New prototype.
	Replaces nautilus_desktop_link_new_from_volume().
	(nautilus_desktop_link_get_drive_or_volume): New prototype.
	Replaces nautilus_desktop_link_get_volume().
	(nautilus_desktop_link_update_from_volume): New prototype.

* libnautilus-private/nautilus-desktop-link.c (struct
	NautilusDesktopLinkDetails): Replaced the "volume" field with
	"drive_or_volume".
	(reread_drive_or_volume): Refresh the link as appropriate from a
	drive or a volume.
	(desktop_link_finalize): Unref the drive or volume appropriately.
	(nautilus_desktop_link_new_from_drive_or_volume): Replacement for
	nautilus_desktop_link_new_from_volume().
	(nautilus_desktop_link_get_drive_or_volume): Replacement for
	nautilus_desktop_link_get_volume().
	(nautilus_desktop_link_update_from_volume): New public function;
	replaces nautilus_desktop_link_new_from_volume().  Updates the
	link's information from a volume.  This does the actual
	transformation of a link from a drive to volume when an unmounted
	drive gets first mounted, and vice-versa.
