GParted reports used figure of active swap space from 4 KiB upwards,
actually 1 page, where as 'swapon -s' reports figures from 0 upwards.
This is because GParted is counting the 1 page swap space overhead as
used space.
# sfdisk -s /dev/sdb1
262144
# mkswap /dev/sdb1
# swapon /dev/sdb1
# swapon -s
Filename Type Size Used Priority
/dev/sdb1 partition 262140 0 -1
For this case GParted reports used as 4 KiB.
(ptn size - swap size = 262144 - 262140 = 4)
Instead make GParted report used figure without any overhead from 0
upwards, matching what 'swapon -s' reports.
Bug 742647 - Swap usage doesn't match figures reported by swapon -s
GParted's primary inbuilt busy detection method is "is the partition
mounted?". A custom method is used for LVM2 PV because its not a
mounted file system.
Make busy detection selectable per file system type.
.fs.busy = FS::NONE (default)
No busy detection.
.fs.busy = FS::GPARTED
Use internal GParted method which checks if the partition is
mounted.
.fs.busy = FS:EXTERNAL
Call the file system type's member function is_busy().
LVM2 PV busy detection changes from a special case to just electing to
call the lvm2_pv::is_busy() method. Linux Software RAID remains a
special case because it's only recognised, but not otherwise supported.

For active swap space read the usage from /proc/swaps. (Linux kernel
uses units of 1 KiB). By definition inactive swap space is 100% free.
$ cat /proc/swaps
Filename Type Size Used Priority
/dev/sda2 partition 5242876 430552 -1
Always set fs.read = FS::EXTERNAL even if /proc/swaps doesn't exist so
that an attempt is made to open the file generating a specific error, in
addition to the generic error.
open("/proc/swaps", O_RDONLY): No such file or directory
Unable to read the contents of this file system!
Because of this some operations may be unavailable.
The cause might be a missing software package.
The following list of software packages is required for linux-
swap file system support: util-linux.
Closes Bug #708107 - Usage of swap space is not reported
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.
Use swaplabel to read the Linux swap label so that 1) a blank label can
be read, and 2) to replace deprecated and removed vol_id.
Vol_id was deprecated in May 2009, superseded by blkid and soon
thereafter removed. Swaplabel is available in util-linux 2.18 from Jun
2010.
If the swaplabel command is not available GParted falls back on reading
the label through the FS_Info cache which uses the blkid command. If
the blkid command is also not available FS_Info cache will *NOT* return
any label and GParted will display blank.
Bug 685656 - GParted doesn't notice when file system label is changed to
blank
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
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
The setting of the write label capability for linux-swap was lost
when it was overwritten in the following commit:
Add support for setting UUID (#667278)
9e96159bb2
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)
* 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 ;)
* 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)
* 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.
* 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
* 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
* hmmz, lots of shimmery internals..
Instead of using a boolean to indicate support for certain
features i now use and enum (NONE, LIBPARTED, EXTENDED).
This allowed me to clean up some stuff that annoyed me ;)
Still.. the core could use a bit more love...
* 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.
* include/GParted_Core.h,
src/GParted_Core.cc,
src/linux_swap.cc: fixed some issues with linux-swap. From now on you need 'mkswap' to create/resize/move linux-swap.
* Replaced boolean 'resize' with 'shrink' and 'grow'. It seems some filesystems only support growing (e.g. xfs) so i need
two flags to control the behaviour of the filesystemclasses.
* include/FileSystem.h,
src/FileSystem.cc: Execute_Command() now returns exit status of executed command
* the filesystemclasses: returnvalue (bool) is now set according to the return status of the command
* 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 =)
