Previously the function erase_filesystem_signatures() was used to clear
file system signatures when a new partition was created and when an
existing partition was formatted with a file system. However this was
only available with libparted <= 2.4 and then only for the file systems
which libparted supports.
Having multiple different file system signatures on a partition leads to
misidentification of file system. For example creating a nilfs2 over
the top of a fat32 file system is detected as a fat32, not nilfs2. This
shows that old file system signatures must be cleared before a new file
system is created.
Fix by always using "wipefs -a /dev/PARTITION" command to clear all old
file system signatures rather than libparted API calls. Failure from
wipefs is only considered a warning so doesn't fail the file system
creation. (This doesn't yet fully meet the "MUST be cleared"
requirement above. Will be fully met later in this patchset). Output
from the wipefs command is displayed as a new sub-step which looks like
this:
v Format /dev/sda7 as xfs 00:00:05
> calibrate /dev/sda14 00:00:01
v clear old file system signatures in /dev/sda7 00:00:01 [NEW]
> wipefs -a /dev/sda7 [NEW]
> set partition type on /dev/sda7 00:00:02
v create new xfs file system 00:00:01
> mkfs.xfs -f -L "" /dev/sda7
Also signatures are only cleared immediately before a new file system is
written and not when an unformatted partition is created. This allows
recovery from accidental partition deletion by re-creating the deleted
partition as unformatted.
Bug #688882 - Improve clearing of file system signatures
Make the generated configure script additionally report these two checks
with their outcome:
checking for gtk_show_uri function... yes
checking for Gtk::MessageDialog::get_message_area() method... yes
1) Require autoconf >= 2.50
(Released May 2001).
2) Rename file to configure.ac
(Recommended with autoconf >= 2.50).
3) Update macro from AC_TRY_RUN to AC_RUN_IFELSE
(As wanted by the autoupdate program).
GParted fails to compile on RHEL/CentOS 5.9 because it doesn't provide
the Gtk::Window::set_default_icon_name() method. The "gtkmm GTK::Window
Class Reference" document says that set_default_icon_name() is available
in gtkmm >= 2.6, however it is not available in RHEL/CentOS 5.9 with
gtkmm 2.10.
Add an autoconf compile and link check for the set_default_icon_name()
method and make GParted only use the method when available.
Bug #695279 - GParted doesn't compile on RHEL / CentOS 5.9
GParted fails to compile on RHEL/CentOS 5.9 because it doesn't provide
the Glib::Regex class. Glib::Regex class requires glibmm >= 2.14,
however RHEL/CentOS 5.9 only provides glibmm 2.12.
Add an autoconf check for the Glib::Regex class and fallback code using
the POSIX regex function. Fall back code is the same as that used prior
to commit:

Enhance regexp_label method to handle unicode characters
Bug #695279 - GParted doesn't compile on RHEL / CentOS 5.9
Only supports detection and creation of f2fs file systems. Requires
f2fs-tools and a blkid with f2fs support, util-linux > 2.22.2.
f2fs-tools v1.1.0 only supports file system creation.
Currently requires util-linux directly from the git repository as f2fs
support was only committed on 5 Feb 2013 and it has not yet been
released.
Closes Bug #695396 - Please apply f2fs patch
After a refresh, instead of having no partition selected, default to the
largest unallocated partition. This allows immediate creation of a new
partition in the unallocated space.
Bug 667365 - Free space should be selected by default
Many filesystems do not implement some of their methods, but had to provide
dummy implementations. Remove all of the dummy implementations and instead
just provide one in the base FileSystem class.
The details view refused to use additional space, even after the window was
expanded, instead continuing to use the scrollbars. Now resizing the
window will be allowed regardless of the state of the details expander, and
the details view will expand to use the extra space. Also request enough
initial width to not need a horizontal scrollbar.
Closes:
Bug 602635 - list of tasks in apply dialog does not expand to the available
vertical space
Bug 662722 - Increase default width of "applying..." dialog to include the
"Details" status icons
There were separate modules for ext3 and ext4 even though there
were virtually no differences with ext2. Remove the duplicate
modules and patch ext2 to serve as a common reference for all
three sub types.
After a move is canceled or fails, an attempt is made to revert the disk to
its previous state. This was moving back all blocks that had already been
copied. Many of the first blocks copied during a move do not overwrite
any valid data, and so do not need put back after an error, so don't bother
doing so.
After a failed or canceled move, the move was reverted, and the filesystem
was fscked while the partition was still in the expanded state encompassing
the original and destination partitions, resulting in errors and
corruption. Move fsck to after the partition table has been restored to
its original state.
After a refresh, instead of having no partition selected, default to the
largest unallocated partition. This allows immediate creation of a new
partition in the unallocated space.

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.
Part of Bug 685740 - Refactor to use asynchronous command execution
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
