Interested operations can now connect a signal to their OperationDetail
to be notified of a cancelation request. The internal copy/move code
will now cleanly stop on cancelation, allowing the partition to be
rolled back to its previous state. This makes canceling a move
perfectly safe.
After clicking cancel, the button changes to "Force Cancel" and is
disabled for 5 seconds. Operations that are safe to cancel will do so
and those that are not will continue to run. Clicking force cancel
asks operations to cancel, even if doing so is unsafe. For the
internal copy/move algorithm, canceling is always safe because an
error results in a rollback operation. Canceling the rollback is
unsafe. For external commands, filesystem modules may indicate
that the command is safe to cancel or not. Canceled commands will
be terminated with SIGINT.
As a result of the new safe cancel vs force cancel distinction, the
scary warning about cancl causing corruption has been moved to
after clicking the force cancel button.

Have the copy code create a background thread to do the actual copying so
that it won't block the main loop.
Part of Bug 685740 - Refactor to use asynchronous command execution
Win_Gparted and Dialog_Progress were creating threads to perform most
functions in the background. Most of the time, the only reason the
threads blocked was to execute an external command. The external command
execution has been changed to spawn the command asynchronously and wait
for completion with a nested main loop. While waiting for completion,
the pipe output is captured via events. In the future, this will allow
for it to be parsed in real time to obtain progress information.
Those tasks in GParted_Core that still block now spawn a background thread
and wait for it to complete with a nested main loop to avoid hanging the
gui.
Part of Bug #685740 - Refactor to use asynchronous command execution
fat16 and fat32 were creating a temp mtoolsrc file to configure the
command to reference a drive letter and ignore certain errors. They have
been changed to pass this information via the command line and environment
instead.
Dialog_Progress was using pthread_create() so that it could later
pthread_cancel() the thread. pthread_cancel() is wildly unsafe and full
of errors. Changed to use Glib's threads like the rest, and only cancel
between operations. Because it can take some time to cancel, disable
the cancel button once it has been clicked once.
Bug 601239 - Please allow 'Cancel after current operation'
Win_Gparted and Dialog_Progress were looping on Gtk::Main::events_pending()
and iteration() with usleeps in between. Use a full mainloop instead and
a proper timeout to trigger pulsebar updates instead of usleeps.
Part of Bug 685740 - Refactor to use asynchronous command execution
Use of these functions is depreciated and making gtk calls in a background
thread still sometimes causes deadlocks or crashes. Change ped exception
handler to instead use an idle function to force the main thread to display
the dialog box.

When moving a MiB aligned primary partition from right to left, the
resulting partition was unexpectedly 1 MiB smaller in size.
From further testing, this occurred only if the move boundaries
overlapped the original partition boundaries.
In cases where the move did not overlap the original partition
boundaries, then the size remained the same.
Closes Bug #695078 - Move of MiB aligned partition right to left
yields unexpected shrink of 1 MiB

Many GNU/Linux distributions conveniently include these docbook
style sheets in a package. This package has been added to the
dependencies for building from source.
Also added and updated are commands related to installation on
OpenSUSE.
Add -I option to 'mkdosfs' command to work around faulty detection of
"complete disks" vs. "partitions".

Thanks to Kano for reporting this!
(This will also be needed if GParted ever allows formatting a device without
partitioning it.)

No longer need to trim fat16, fat32 and xfs labels as all labels are
limited to their maximum lengths during entry.
Bug #689318 - filesystem type specific support for partition name
maximum length
For a reiser4 file system with exactly the maximum size 16 character
label, debugfs.reiser4 may include junk at the end of the label it
prints. (It reads the label into a 16 character array and prints it as
a string, but there isn't a nul terminating character).
# mkfs.reiser4 --yes --label abcdefghij123456 /dev/sda13
# debugfs.reiser4 /dev/sda13 2> /dev/null | grep label:
label: abcdefghij123456!
Trim the read label to at most 16 characters.

Active Linux software RAID devices are detected in the
Proc_Partitions_Info method. Hence the SWRaid method is no longer
required.
Removal of the SWRaid method fixes the problem with the error message:
Could not stat device /dev/md/0 - No such file or directory
This fixes the problem because we no longer use "mdadm --examine
--scan" in an attempt to detect Linux software RAID devices. The
mdadm command was returning device names such as /dev/md/0, which are
incorrect for GParted.
NOTE: With this change, GParted no longer requires the mdadm command
to detect Linux software RAID devices.
Closes Bug #678379 - Could not stat device /dev/md/0 - No such file or
directory
Add regular expression to detect the device entry only (e.g., md127)
and not the partitions (e.g., md127p1).
Linux software RAID devices are listed in /proc/partitions as follows:
# cat /proc/partitions
major minor #blocks name
9 127 523968 md127
259 0 131072 md127p1
259 1 262144 md127p2

104 2 24097 cciss/c0d0p2
104 3 143203410 cciss/c0d0p3
The previous regular expression was too broad, and would match many
other forms, including Linux software RAID devices such as md127.

This problem with the regexp was discovered while investigating a
problem with Linux software RAID device detection.
The regular expression has been tightened up to match the following
hardware RAID controllers:

In certain situations with a mixture of partition alignments, the MiB
alignment option would try to set the end of a logical partition
beyond the end of the extended partition. This, of course, is an
invalid partition geometry and the libparted library correctly reports
failure when this is attempted.
This enhancement to MiB alignment adds a check to see if the end of
the logical partition would be beyond the extended partition, and
adjusts the end of the logical partition if required.
Closes Bug #686668 - Growing logical partition overlaps end of
extended partition
Prior to this enhancement, GParted ignored the status of the partition
grow operation, and attempted to grow the file system.
Now we check the status of the partition grow operation prior to
growing the file system.
Part of Bug #686668 - Growing logical partition overlaps end of
extended partition
A reiser4 file system with a blank label is displayed as "<none>" by
debugfs.reiser4 and therefore GParted too.
# mkfs.reiser4 -y -L "" -f /dev/sda14
# debugfs.reiser4 /dev/sda14 2> /dev/null | grep label:
label: <none>
Additionally when displaying the Partition Information the following
warning is written to the terminal:
(gpartedbin:19609): Gtk-WARNING **: Failed to set text from markup
due to error parsing markup: Error on line 1 char 23: Element
'markup' was closed, but the currently open element is 'none'
Fix by just assuming "<none>" always means blank. If someone really
does set the label to "<none>" it won't be displayed. This is equlivant
to how btrfs and nilfs2 are already handled.
Closes bug 688760 - GParted displays blank resier4 label as <none>
If gksu was installed on a KDE system (tested with kubuntu 12.04 LTS),
then gksu would prompt for the password three times and always fail to
load gparted. In a prior version of kubuntu 8.04 LTS, gksu would
properly invoke gparted from the "K --> System --> GParted" menu
entry.
Since gksudo also works on KDE (and kubuntu 12.04 LTS), add gksudo to
the root privilege invocation search list ahead of gksu.
Note that gksu has been kept for backwards compatibility with systems
that provide only gksu and not gksudo.
Related to Bug #687813 - Use kdesudo on KDE, as gksu is not
installed by default
Normally gksu is not installed by default on KDE systems. When
compiling and installing gparted on a KDE system without gksu, the
desktop menu entry would try to run gparted as the user, and not with
root privileges.
To fix this, add kdesudo to the search list of root privilege
invocation programs.
Closes Bug #687813 - Use kdesudo on KDE, as gksu is not installed by
default
1) lp_disk is not used and assigned NULL so doesn't need closing.
2) lp_device is already ped_device_open()ed and ped_device_close()d
within the above while loop. lp_device will be set to NULL when the
while loop ends so this doesn't need closing either. Hence
close_device_and_disk() is always passed with two NULL pointers and is a
no operation so can be removed.
They were used like global variables. Now they are moved to the
functions that actually use them to make clearer how the data flow is.
