Using e2image to copy a file system looks like this. (Intermediate
progress lines which are constantly overwritten are indicated with ">").

Note that the copying figures are reported in file system block size
units and the progress information is written to stderr, hence needing
these two previous commits:
Record file system block size where known (#760709)
Call any FS specific progress trackers for stderr updates too (#760709)
Add progress tracking function for e2image command. Also tracks when
the text progress indicator has passed in the output so that the
progress bar can be stopped as well as started when needed.
Bug 760709 - Add progress bars to XFS and EXT2/3/4 file system specific
copy methods
Adapt the ext2 resize progress tracker to the new ProgressBar class.
Also update the progress function to track when text progress bars have
completely passed in the output so that the progress bar can be stopped
as well as started when needed.
Bug 760709 - Add progress bars to XFS and EXT2/3/4 file system specific
copy methods
Lots of files which use the Partition class relied on the declaration
being included via other header files. This is bad practice.
Add #include "Partition.h" into every file which uses the Partition
class which doesn't already include it. Header file #include guards are
specifically to allow this.
Capture and parse the progress reports of ntfsresize and resize2fs and
update the dialog progress bar.

RHEL / CentOS 5.6 and later officially support ext4 file system [1].
From RHEL / CentOS 5.3 ext4 file system was included as a technology
preview. Ext4 file system tools are in a separate package e4fsprogs,
using uniquely named commands. The standard e2fsprogs commands only
support ext2 and ext3 file systems.
# mkfs.ext4 /dev/sdb3
# tune2fs -l /dev/sdb3
tune2fs 1.39 (29-May-2006)

For ext4 only, search for the e4fsprogs specific commands first and the
standard e2fsprogs commands second.

Bug #738706 - GParted doesn't support ext4 on RHEL/CentOS 5.x
Use e2image features added in e2fsprogs 1.42.9 to move/copy
an ext[234] file system more efficiently by skipping unused blocks.
Fall back to the internal copy algorithm if e2image is not found
or does not support move/copy.

This is part of parent bug:
Bug #721455 - Obsolete info in license text on multiple modules
and GNOME Goal:
https://wiki.gnome.org/Initiatives/GnomeGoals/Proposals
* verify all source files to make sure they have a license and a
copyright, and that both are up-to-date
Bug #721565 - License text contains obsolete FSF postal address
Include guards need to be unique within GParted code and all included
library header files.
http://en.wikipedia.org/wiki/Include_guard#Difficulties
Use this model for all include guards:
#ifndef GPARTED_FILE_NAME_H
#define GPARTED_FILE_NAME_H
...
#endif /* GPARTED_FILE_NAME_H */
Closes Bug #539297 - Make include guards unique
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.
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.
This commit only adds a remove() method to every file system and an
optional call to it in the relevant operations. All remove() methods
are no operations and not enabled.
The remove() method provides explicit controlled removal of a file
system before the partition is deleted or overwritten by being formatted
or pasted into. When implemented, it appears as an extra step in the
relevant operation. The file system specific remove() method is
explicitly allowed to fail and stop the operations currently being
applied.
This is different to the existing erase_filesystem_signatures() which
wipes any previous file system signatures immediately before a new file
system is written to ensure there is no possibility of the partition
containing two or more different file system signatures. It never fails
or reports anything to the user.
NOTE:
Most file systems should NOT implement a remove() method as it will
prevent recovery from accidental partition deletion.
Bug #670171 - Add LVM PV read-write support
Add the ability to set a new random UUID on file systems that provide
the appropriate tools to perform this action.
Update the help manual to include this new functionality. Also add
reference links to "setting a partition label" and "changing a
partition UUID" in the "copying and pasting a partition" section.
This patch does not include setting the UUID on an NTFS file system.
Bug #667278 - Add support for setting UUID
Bug #608308 - fix documentation - Copying and Pasting a Partition
Restore copyright entries by original author to those of his last
known repository commit titled "released gparted-0.3.4 on
LarryT's request." on Feb 25, 2007.
Add my own copyright entries for files in which I changed source
code. Files in which I only made spelling changes do not have my
copyright entry added.
* added support for reading volumelabels. Atm we only read ext2/3, but
the infrastructure for adding the other filesystems is in place.
It's simply a matter of finding the right commands and parsing the
output. (see #338528 for more info)
* added detailed progressfeedback. It still needs some polishing, but
is already far better then the old situation. And what's more, it's
finally threadsafe :p
* The Filesystemclasses: Changed 'bool Create( const Glib::ustring & device_path, const Partition & new_partition )'
to 'bool Create( const Partition & new_partition )'. Since i now use external tools for all filesystems, the partitionpath will suffice.
* Again way too many chances to create a detailed entry (i'm glad i'm the only dev atm :P ).
Resizing of ext2/3 works perfect now. I've even tested it on the partition holding my SG seasons =)
Implemented checking of filesystems (only internally used atm).
Done some overall tweaking, finetuning etc.. release 0.0.7 is getting shape.
* Rewrote a large part of gparteds internal code. Filesystemssupport is now much more separated from the rest of gparted and
adding support for other filesystems should be a piece of cake now (hope that's true :P)
It still needs a lot of love, but the foundations are laid =)
