The String::ucompose method is for easy, i18n-friendly composition of
strings with Gtkmm. From past experience, String::ucompose should not
be used to build command lines due to differences in how locales handle
number translation. More specifically, not all locales use number
separators (spaces, commas or periods) and the decimal separator
(period or comma) in the same way.
The problem with using String::ucompose for command lines was
originally encountered and corrected in the following commit:

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
Many file systems are capable of growing while mounted, and a few can
even shrink. This support must be explicitly enabled at configure time
with the --enable-online-resize flag and depends on a patched libparted.
Also requires kernel >= 3.6 for partition resizing, even if the
partition is in use (BLKPG_RESIZE_PARTITION).
Thanks to Mike Fleetwood for double check mark idea instead of a second
column to show the online grow/shrink.
Bug #694622 - Add support for online resize
It was difficult to retrieve whether a filesystem's label can be set on reformat.
The read_label flag can't be used as it decides whether to use the logic in the filesystem class
rather than the fallback in GParted::set_device_partitions, to determine the label of a partition.
The create_with_label flag is NONE for file systems that we cannot format with a
label (or that we cannot format at all).
The value is usually EXTERNAL for file systems that we can format with a label.
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.
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
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
GParted doesn't notice when a file system label is changed to blank.
GParted first calls the file system specific read_label() method. When
the label is blank read_label() correctly sets partition.label to the
zero length string. Second GParted_Core::set_device_partitions() treats
the zero length string to mean that the label is unset and calls
FS_Info::get_label() to retrieve it from the cache of blkid output.
Blkid also doesn't notice when the file system label has been changed to
blank so reports the previous label. Hence GParted displays the
previous file system label.
Fix by making label a private member variable of the class Partition and
providing access methods set_label(), get_label() and label_known()
which track whether the label has been set or not. This only fixes the
fault for file systems which use file system specific commands to read
the label and when these tools are installed. Otherwise GParted uses,
or has to fall back on using, the buggy blkid command to read the file
system label.
NOTE:
Many of the file system specific read_label() methods use a tool which
outputs more than just the label and use Utils::regexp_label() to match
leading text and the label itself. If the surrounding text changes or
disappears altogether to indicated a blank label, regexp_label() doesn't
match anything and returns the zero length string. This is exactly
what is required and is passed to set_label() to set the label to blank.
Bug 685656 - GParted doesn't notice when file system label is changed to
blank
Each file system class can now choose how the size and free space of the
file system is determined when it is mounted.
.fs.online_read = FS::NONE (default)
Do nothing. Don't get the file system size and free space.
.fs.online_read = FS::GPARTED
Use internal GParted method which calls statvfs() system call on
the mounted file system.
.fs.online_read = FS::EXTERNAL
Call the file system's member function set_used_sectors(). This
is the same function as called when the file system is not
mounted. It can determine if the file system is mounted or not
by testing partition.busy and acting accordingly.
This means that determining the size and free space of active LVM2
Physical Volumes is no longer a special case. Instead the lvm2_pv class
just elects to have its set_used_sectors() method called for both the
active and deactive cases.
Bug #683255 - ext2: statvfs differs from dumpe2fs (x MB unallocated
space within the partition)
Use the new RFC 4122 none Nil UUID regular expression to validate the
UUID read in all the Linux native file system specific read_uuid()
methods. No longer need to explicitly exclude "<none>" or all zeros Nil
UUID as the regular expression does this.
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
Update file system specific implementations to set the size and free
space, thus allowing the unallocated space in the partition to be
calculated, for the following unmounted file systems:
btrfs, ext2, ext3, ext4, fat16, fat32, jfs, nilfs2, ntfs, reiserfs,
reiser4, xfs
Bug #499202 - gparted does not see the difference if partition size
differs from filesystem size
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
With the removal of the 512 byte constants, such as MEBIBYTE, it
was possible to rename the _FACTOR constants back to BYTE
constants. The _FACTOR constants, such as MEBI_FACTOR, were a
temporary measure to help in the transition to support devices
with sector sizes > 512 bytes.
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.
* src/GParted_Core: Replaced std::abs with llabs (see #357691)
* src/hfs.cc,
src/xfs.cc: added support for reading of volumelabel
* src/reiserfs.cc: added Fixme
* 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)
* src/ext2.cc
src/ext3.cc
src/fat16.cc
src/fat32.cc
src/jfs.cc
src/ntfs.cc
src/reiser4.cc
src/reiserfs.cc
src/xfs.cc: be a bit more verbose on errior in set_used_sectors()
* improved errorhandling a bit. At the initialscan we store
errors/warnings now in a list per partition and show the in the
partitioninfo dialog.
While executing an operation we collect all libparted exceptions in
a list and attach this list to the operationdetails when everything
is done.
* Use ped_device_read and ped_device_write instead of 'dd' to copy
filesystems.
Modified progressdetails to provide more detailed feedback about a
process.
Basicly these were all changes to the infrastructure to make the
incorporation of the 'move-code' a bit easier.
( sorry, not in the mood to list all affected files ;)
* src/ext2.cc,
src/ext3.cc,
src/fat16.cc,
src/fat32.cc,
src/jfs.cc,
src/ntfs.cc,
src/reiser4.cc,
src/reiserfs.cc,
src/xfs.cc: changed statusmessage, fixed issue with exit_status and
tested/confirmed succesfull usage of Partition::get_path() in
Set_Used_Sectors() of all filesystems.
* changed the way devices and partitions store their devicepaths.
Instead of holding a 'realpath' and a symbolic path we store paths
in a list. This allows for improved detection of mountpoins, free
space, etc..
Also fixed a nasty bug which showed up when you copy a partition
from one device to another. (thanks to mario for the report)
* in some places i still used MiB's instead of sectors to store sizes.
this has been fixed everywhere. Only the spinbuttons still use
MiB's. I have a few ideas on how to solve this, but i'll take it up
with #usability first.
* wrap mount/umount/swapon/swapoff instead of implementing it
ourselves (#330641)
* moved execute_command() to Utils and made the filesystems use it. All
in all this decreased the size of the binary with 10% and made stuff
more readable.
* src/Utils.cc: fixed small bug in unmount()
* src/jfs.cc,
src/xfs.cc: check if error actually contains data before adding it
to the feedbackdata. (this prevents empty rows in the operationtree)
* use Glib::get_tmp_dir() instead of hardcoding it as '/tmp'
* use Glib::find_program_in_path() instead af a system/which combi
* display current device in windowtitle
