Enable new fs resize library available with parted-3.1 (#668281) The parted-3.1 release brings back FAT16/FAT32 and HFS/HFS+ file system resize capabilities in a new libparted fs resize library. The following operations are again available when GParted is linked with parted-3.1: FAT16 - grow and shrink FAT32 - grow and shrink HFS - shrink HFS+ - shrink Note that there is a difference in how move actions are handled for FAT16/FAT32 file systems based on parted version. When GParted is linked with parted >= 3.0: FAT16 - move performed internally by GParted FAT32 - move performed internally by GParted When GParted is linked with parted < 3.0: FAT16 - move performed by libparted FAT32 - move performed by libparted Thanks goes to Jim Meyering for restoring these file system resizing capabilities in Parted 3.1 with a new libparted fs resize library. Closes Bug #668281 - minimal file-system resize API? (FAT and HFS* only)

void set_devices( std::vector<Device> & devices ) ;
Reduce threading (#685740) 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.

Erase file system signatures before creating a partition table (#743181) When writing "loop" partition table over the top of some whole disk device file system types GParted continued to show those whole disk device file systems rather than the virtual unknown partition from the "loop" partition table. This affected btrfs, jfs, reiser4 and reiserfs. It occurred because of several factors: 1) Libparted only zeroed the first and last 9.5 KiB (assuming 512 byte sectors) of the device before writing a new partition table. See ped_disk_clobber(). 2) These file systems have their super blocks and therefore signatures after the first 9.5 KiB. 3) Whole disk device file system detection is performed using blkid before checking for a libparted "loop" partition table. See GParted_Core::set_devices_thread(). Ref: libparted 3.2: disk.c:ped_disk_clobber() http://git.savannah.gnu.org/cgit/parted.git/tree/libparted/disk.c?id=v3.2#n302 Fix by always erasing any possible file system signatures on the device before creating a new "loop" partition table. NOTE: This is typically taking up to 0.5 seconds in my testing on a 5400 RPM hard drive, during which time the GParted UI is hung and the create partition table dialog shows the apply button pressed but no other progress indication.

Fix failure to recognise whole disk file systems in certain cases (#743181) When the following conditions were met GParted would fail to recognise a newly created whole disk device file system, and instead show an unknown file system filling the disk: 1) Disk was previously partitioned and contained at least one partition. 2) Using libparted version 2.0 to 3.0 inclusive. Initial status: # blkid | fgrep sdc # fgrep sdc /proc/partitions 8 32 976762584 sdc 8 33 104857600 sdc1 # parted /dev/sdc GNU Parted 2.4 Using /dev/sdc Welcome to GNU Parted!

However the kernel still has old partition details. This was fixed in libparted 3.1 by commit: http://git.savannah.gnu.org/cgit/parted.git/commit/?id=f5c909c0cd50ed52a48dae6d35907dc08b137e88 libparted: remove has_partitions check to allow loopback partitions Fix by deleting old partitions before creating the loop table when compiled with a broken version of libparted. The GParted UI provides no feedback while a new partition table is created, and with some versions of GTK the UI become unresponsive too, so it is important to be as fast as possible. Evaluated three different methods, deleting 15 and 22 MSDOS partitions on a physical 5400 RPM hard drive using libparted 2.4: M1) Delete and commit one partition at a time. Takes up to 24 seconds to delete 15 partitions. With 22 partitions libparted always reports finding some of the partitions busy and unable to inform the kernel about the modifications. Too slow and doesn't work. M2) Delete all partitions in one go and commit once. Takes up to 1.4 seconds to delete either 15 or 22 partitions. Never removes partitions 17 and higher from the kernel. Doesn't work. M3) Write GPT table (letting libparted delete any old partitions). Takes up to 0.8 seconds to delete either 15 or 22 partitions. Fast and works. Use method 3 - write a GPT table thus using libparted code to inform the kernel of the old partition deletions. Bug 743181 - Add unpartitioned drive read-write support

Disallow resizing of LVM2 PVs which are members of exported VGs (#670171) When an inactive LVM2 Volume Group is exported it makes it unknown to the local system, ready for moving the member Physical Volumes to another system, where the VG can be imported and used. In this state a PV can't be resized. # lvm pvresize /dev/sda10 Volume group Test-VG1 is exported Unable to read volume group "Test-VG1". 0 physical volume(s) resized / 1 physical volume(s) not resized # echo $? 5 Fix this by preventing resizing of such a PV. This has been coded in a generic way using new function filesystem_resize_disallowed() to determine whether a file system is allowed to be resized or not. For a file system which can be resized, but is currently not allowed to be resized, the behaviour is as follows: 1) Pasting into unallocated space is limited to creating a new partition which is the same size as the copied partition. 2) Resizing the partition is disallowed, only moving the partition is allowed. 3) Pasting into an existing partition will only copy the file system. If the destination partition is larger a warning will report that growing the file system is not currently allowed. 4) Checking a partition will also report a warning that growing the file system is not currently allowed. This is exactly the same behaviour as for a file system which does not implement resizing, except for a different warning message. Bug #670171 - Add LVM PV read-write support

Fallback to reading mount command output instead of /etc/mtab (#723842) With linux 3.5 and later, the device used to mount a btrfs file system is updated in /proc/mounts when the previous mounting device is removed from the file system. Most recent distributions make /etc/mtab a symbolic link to /proc/mounts. However some still have /etc/mtab as a plain file only updated by mount and umount, thus showing the old device name which is no longer part of the file system. On Ubuntu 13.10, which has /etc/mtab as a plain file managed by mount and umount: # mkfs.btrfs /dev/sdb1 # mount /dev/sdb1 /mnt/1 # btrfs device add /dev/sdb2 /mnt/1 # btrfs device delete /dev/sdb1 /mnt/1 # sync # btrfs filesystem show /dev/sdb1 # btrfs filesystem show /dev/sdb2 Label: none uuid: e47775a6-e5ad-4fb4-9ea4-1570aa5b4009 Total devices 2 FS bytes used 28.00KB devid 2 size 2.00GB used 272.00MB path /dev/sdb2 # fgrep btrfs /proc/mounts /dev/sdb2 /mnt/1 btrfs rw,relatime,space_cache 0 0 # ls -l /etc/mtab -rw-r--r-- 1 root root 842 Apr 15 19:41 /etc/mtab # fgrep btrfs /etc/mtab /dev/sdb1 /mnt/1 btrfs rw 0 0 This causes GParted to report /dev/sdb1 as busy and mounted at /mnt/1 when it is no longer mounted. This effects recent releases of Ubuntu, 13.04, 13.10 and 14.04. Either /etc/mtab is a symlink and is identical to /proc/mounts or /etc/mtab is a plain file with wrong information. Fix by not reading mounted file systems from /etc/mtab.

Fallback to reading mount command output instead of /etc/mtab (#723842) With linux 3.5 and later, the device used to mount a btrfs file system is updated in /proc/mounts when the previous mounting device is removed from the file system. Most recent distributions make /etc/mtab a symbolic link to /proc/mounts. However some still have /etc/mtab as a plain file only updated by mount and umount, thus showing the old device name which is no longer part of the file system. On Ubuntu 13.10, which has /etc/mtab as a plain file managed by mount and umount: # mkfs.btrfs /dev/sdb1 # mount /dev/sdb1 /mnt/1 # btrfs device add /dev/sdb2 /mnt/1 # btrfs device delete /dev/sdb1 /mnt/1 # sync # btrfs filesystem show /dev/sdb1 # btrfs filesystem show /dev/sdb2 Label: none uuid: e47775a6-e5ad-4fb4-9ea4-1570aa5b4009 Total devices 2 FS bytes used 28.00KB devid 2 size 2.00GB used 272.00MB path /dev/sdb2 # fgrep btrfs /proc/mounts /dev/sdb2 /mnt/1 btrfs rw,relatime,space_cache 0 0 # ls -l /etc/mtab -rw-r--r-- 1 root root 842 Apr 15 19:41 /etc/mtab # fgrep btrfs /etc/mtab /dev/sdb1 /mnt/1 btrfs rw 0 0 This causes GParted to report /dev/sdb1 as busy and mounted at /mnt/1 when it is no longer mounted. This effects recent releases of Ubuntu, 13.04, 13.10 and 14.04. Either /etc/mtab is a symlink and is identical to /proc/mounts or /etc/mtab is a plain file with wrong information. Fix by not reading mounted file systems from /etc/mtab. However old distributions only contain 'rootfs' and '/dev/root' device names for the / (root) file system with '/dev/root' being a block device rather than a symlink to the true device. For example from CentOS 5.x: # fgrep ' / ' /proc/mounts rootfs / rootfs rw 0 0 /dev/root / ext3 rw,data=ordered 0 0 # ls -l /dev/root brw------- 1 root root 8, 3 Jun 4 2013 /dev/root This prevents identification, and therefore busy detection, of the device containing the / (root) file system.

Display whole disk file systems via partition table "none" (#741430) For file systems which libparted recognises, when found on the whole disk device, it reports with partition table "loop" and a partition covering the whole disk.

Display mount points for multi-device btrfs file systems (#723842) Linux can only show a single device name in /proc/mounts and /etc/mtab for each mounted btrfs, even if it is a multi-device file system. So GParted only shows a mount point for one of the devices in the btrfs, no matter how many devices are part of the file system. # mkfs.btrfs /dev/sdb1 /dev/sdb2 # btrfs filesystem show /dev/sdb1 Label: none uuid: 36eb51a2-2927-4c92-820f-b2f0b5cdae50 Total devices 2 FS bytes used 156.00KB devid 2 size 2.00GB used 512.00MB path /dev/sdb2 devid 1 size 2.00GB used 240.75MB path /dev/sdb1 # mount /dev/sdb1 /mnt/1 # grep btrfs /proc/mounts /dev/sdb1 /mnt/1 btrfs rw,seclabel,relatime,ssd,space_cache 0 0 GParted only shows the mount point for /dev/sdb1 as /mnt/1, but nothing for /dev/sdb2. Make GParted report the same mount point for all devices included in a multi-device btrfs file system. Add btrfs specific get_mount_device() method to report the mounting device, if any, for the btrfs file system in the occupying the device in question. Uses the existing cache of btrfs file system device membership. Also extract common code from GParted_Core:: set_mountpoints() into set_mountpoints_helper().

LVM2 PV busy detection changes from a special case to just electing to call the lvm2_pv::is_busy() method.

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.

Enable compile and link with libparted 3.0 (#651559) The release of (lib)parted 3.0 includes a change to the Application Programing Interface - API. Most importantly, libparted 3.0 removes many file system specific function calls, and hence the capabilities provided by these functions. In order for GParted to compile and link with libparted 3.0, this libparted functionality is lost. Specifically, the functionality that is lost when GParted is compiled and linked with libparted 3.0 is as follows: - Loss of ability to grow and shrink FAT16 and FAT32 file systems - Loss of ability to shrink HFS and HFS+ file systems - Loss of ability to determine used and unused sectors in HFS and HFS+ file systems - Loss of ability to erase file system signatures on partition create and format It is hoped that other free software projects will include some or all of the above lost functionality, which can then be added back to GParted. This commit includes a change in how FAT16 and FAT32 file systems are moved. Specifically the move is now performed internally by GParted when linked with libparted 3.0. The move functionality is provided by libparted for prior libparted versions (e.g. less than 3.0). This is the final enhancement in a series of commits that enable GParted to compile with libparted version 3.0. Closes Bug #651559 - Doesn't compile against parted 3.0

Add file system specific remove() methods (#670171) 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.

Most importantly, libparted 3.0 removes many file system specific function calls, and hence the capabilities provided by these functions. In order for GParted to compile and link with libparted 3.0, this libparted functionality is lost. Specifically, the functionality that is lost when GParted is compiled and linked with libparted 3.0 is as follows: - Loss of ability to grow and shrink FAT16 and FAT32 file systems - Loss of ability to shrink HFS and HFS+ file systems - Loss of ability to determine used and unused sectors in HFS and HFS+ file systems - Loss of ability to erase file system signatures on partition create and format It is hoped that other free software projects will include some or all of the above lost functionality, which can then be added back to GParted. This commit includes a change in how FAT16 and FAT32 file systems are moved. Specifically the move is now performed internally by GParted when linked with libparted 3.0. The move functionality is provided by libparted for prior libparted versions (e.g. less than 3.0). This is the final enhancement in a series of commits that enable GParted to compile with libparted version 3.0. Closes Bug #651559 - Doesn't compile against parted 3.0

OperationDetail & operationdetail,
Add proper cancel support (#601239) 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.

Use wipefs to clear old signatures before creating new file systems (#688882) 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
