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)

Remove "../include/" from GParted header #includes It made the code look a little messy, is easily resolved in the build system and made the dependencies more complicated than needed. Each GParted header was tracked via multiple different names (different numbers of "../include/" prefixes). For example just looking at how DialogFeatures.o depends on Utils.h: $ cd src $ make DialogFeatures.o $ egrep ' [^ ]*Utils.h' .deps/DialogFeatures.Po ../include/DialogFeatures.h ../include/../include/Utils.h \ ../include/../include/../include/../include/../include/../include/Utils.h \ ../include/../include/../include/Utils.h \ After removing "../include/" from the GParted header #includes, just need to add "-I../include" to the compile command via the AM_CPPFLAGS in src/Makefile.am.

Split FILESYSTEMS and FILESYSTEM_MAP into separate module (!49) GParted_Core::FILESYSTEMS and ::FILESYSTEM_MAP and the methods that query and manipulate them are self-contained. Therefore move them into a separate SupportedFileSystems module. Also having a single class maintaining all FileSystem interface objects will make testing all the file system types much easier as there will be no need to duplicate this functionality in the test.

Extract common code into GParted_Core::get_filesystem_limits() (#787204) There are multiple repetitions of the same code getting a FileSystem object, checking for NULL and then calling the file system specific get_filesystem_limits(). Extract that into a common function. GParted_Core::get_filesystem_limits() can't use the file system from the passed Partition object because that is the current file system which will be different from the intended file system for new and format operations. So would look up the wrong derived FileSystem specific object and call the wrong get_filesystem_limits(). Hence still needing fstype as a separate parameter to pass the intended file system.

Add initial unit test of erase_filesystem_signatures() (#220) Initially just testing erasing of Intel Software RAID signatures. Chosen because it was expected to work, but turned out not to be true in all cases.

Remember result of searching the PATH for the hdparm command (#751251) Previously on every refresh for every device, GParted was searching the PATH to discover if the hdparm command existed. Stracing GParted showed that calling Glib::find_program_in_path("hdparm") made the following OS calls: access("/usr/lib64/qt-3.3/bin/hdparm", X_OK) = -1 ENOENT (No such file or directory) access("/usr/local/sbin/hdparm", X_OK) = -1 ENOENT (No such file or directory) access("/usr/local/bin/hdparm", X_OK) = -1 ENOENT (No such file or directory) access("/sbin/hdparm", X_OK) = 0 getuid() = 0 stat("/sbin/hdparm", {st_mode=S_IFREG|0755, st_size=137, ...}) = 0 stat("/sbin/hdparm", {st_mode=S_IFREG|0755, st_size=137, ...}) = 0 The Linux VFS is very fast but repeatedly doing this is wasteful. Remember the result of searching the PATH for the hdparm command at startup and refresh this when the [Rescan For Supported Actions] button is pressed in the File System Support dialog. This is the same as GParted already does for file system specific commands and their capabilities. Bug 751251 - Show serial number in device information

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.

Separate partition alignment from validation (#48) PATCHSET OVERVIEW A user had 2 adjacent partitions which were aligned to multiples of 33553920 bytes (32 MiB - 512 bytes), not MiB or cylinders. As far as GParted is concerned this is not aligned. The second partition contained closed LUKS encrypted data. Recreate this setup with: # truncate -s 200G /tmp/disk.img # losetup -f --show /tmp/disk.img /dev/loop0 # sfdisk -u S /dev/loop0 << EOF 65535 2162655 83 2228190 78904140 83 EOF # partprobe /dev/loop0 # echo -n badpassword | cryptsetup luksFormat /dev/loop0p2 - When trying to move the second LUKS encrypted partition to the right by any amount, with the default MiB alignment, GParted displays this error dialog and fails to even queue the operation: Could not add this operation to the list A partition with used sectors (78907392) greater than its length (78905344) is not valid [ OK ] Overview of the steps involved: 1. The Resize/Move dialog composed a new partition to start a whole multiple of MiB after the end of the previous non-aligned partition. The new partition also had it's size increased to a whole multiple of MiB, to 78907392 sectors (38529 MiB) which was 1.59 MiB larger than before. Neither the start or end of the new partition are aligned at this point. 2. Win_GParted::activate_resize() applied the change back to the closed LUKS partition object, additionally making the used sectors equal to the partition size. (To match the fact that when opened the LUKS mapping it will automatically fill the new larger partition size). 3. GParted_Core::snap_to_mebibyte() then aligned the partition start and end to whole MiB boundaries, reducing the partition size in the process to 78905344 (38528 MiB). 4. GParted_Core::snap_to_alignment() reported the error saying that it couldn't add the operation to the list because it was invalid to have the file system used sectors larger than the partition size. Fix this by having the snap to alignment adjustments applied before the dialogs update any associated file system usage. Specifically the Resize/Move, Paste (into new) and Create New dialogs as these are the only ones which either create or modify partition boundaries. Validation done by snap_to_alignment() will continue to occur at the current point when the operation is added to the list. THIS COMMIT snap_to_alignment() is doing two different jobs, it is (1) optionally adjusting the new partition boundaries for MiB or Cylinder alignment; and (2) checking that the partition boundaries and file system usage are valid. Split those into two different functions (1) snap_to_alignment() and (2) valid_partition(). For now valid_partition() still calls snap_to_alignment() so there is no functional change with this commit. Closes #48 - Error when moving locked LUKS-encrypted partition

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.

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

Refactor get_filesystem_object() The function was using std::map::count() [1] to test if the file system entry existed in the map before looking up the value using std::map::operator[] to avoid having operator[] inserting elements which don't exist [2]. Rewrite using std::map::find() [3] so that map is only searched once, and so that it is more obvious what is happening without having to know the subtleties of std::map::count() and ::operator[]. [1] std::map::count() http://www.cplusplus.com/reference/map/map/count/ "Searches the container for elements with a key equivalent to k and returns the number of matches. Because all elements in a map container are unique, the function can only return 1 (if the element is found) or zero (otherwise). " [2] std::map::operator[] http://www.cplusplus.com/reference/map/map/operator[]/ "If k does not match the key of any element in the container, the function inserts a new element with that key and returns a reference to its mapped value. Notice that this always increases the container size by one, even if no mapped value is assigned to the element (the element is constructed using its default constructor).

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

Consolidate down to a single insert_unallocated() implementation (#759726) GParted_Core and Operation classes both have an insert_unallocated() method which do the same thing with very nearly identical code. Both methods insert unallocated partitions into the vector of partitions within the specified range of sectors to fill in any gaps larger than 1 MiB. The only difference was how the two methods got the device path; the GParted_Core class method got it via a parameter and the Operation class method got it by calling get_path() on its device member variable. The GParted_Core insert_unallocated() method gets called during device scanning and the Operation one gets called when constructing the visual for a pending operation. Consolidate down to a single insert_unallocated() implementation by making the Operation class method call the GParted_Core class method. Make the GParted_Core class method static and public so that it can be called using the class name from outside the class. Bug 759726 - Implement Partition object polymorphism

GParted reports the usage of /dev/sdb1 as: Partition Mount Point Size Used Unused Unallocated /dev/sdb1 /dev/md1 1.00GiB 0.00B 731.04MiB 292.96MiB However GParted should have reported the usage as "---" for unknown because it isn't coded to query the size of the SWRAID member within a partition. The fault has been bisected to this commit: Extend un/mounting and usage reporting to unsupported file systems (!13) 95903efb1f284f3d6819f38e894dc6c3464b2183 What happens for busy Linux Software RAID array members: * GParted_Core::is_busy() has custom code to identify busy members. * GParted_Core::set_mountpoints() has custom code to add the array device name as the "mount point" of the member. * GParted_Core::set_used_sectors() falls into the else not a supported file system (because SWRAID doesn't have a derived FileSystem implementation class). * GParted_Core::mounted_set_used_sectors() is called to get the file system usage of mounted, but unsupported file systems, such as UFS and any others. * Utils::get_mounted_filesystem_usage() is called which queries the kernel using statvfs() and gets the file system usage of the /dev virtual file system because the array device name will always start /dev. Fix by ensuring that GParted only asks the kernel for the usage of paths which it knows are mount points of mounted file systems. (As read from /proc/mounts and cached in the Mount_Info module). Also rename the method, by inserting "_fs", to mounted_fs_set_used_sectors() to remind us that it is for mounted *file systems* only.

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

bool delete_partition( const Partition & partition, OperationDetail & operationdetail );
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.

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.

Add libparted ped_file_system_resize thread to avoid blocking GUI (#737022) Since GParted commit 52a2a9b "Reduce threading (#685740)", released in GParted 0.15.0, application of operations occurs in the main thread running the UI, therefore long running libparted actions such as resizing a FAT16 or FAT32 file system hang the UI for as long as it take to complete the operation. https://git.gnome.org/browse/gparted/commit/?id=52a2a9b00a32996921ace055e71d0e09fb33c5fe Though this problem exists for all libparted actions, it is particularly noticeable when performing a large resize of fat16/fat32/hfs/hfs+ file systems. To address this significant cause of an unresponsive GUI, this enhancement adds threading to the libparted ped_file_system_resize function call.

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

Implement rollback of failed partition resize/move steps (#791875) Even after implementing a fix for bug 790418 "Unable to inform the kernel of the change message may lead to corrupted partition table" GParted/libparted can still encounter errors informing the kernel of the new partition layout. This has been seen with GParted on CentOS 7 with libparted 3.1. In such a case the partition has been successfully written to the disk but just informing the kernel failed. This is a problem because when a partition is being moved in advance of a file system move step, failure to inform the kernel leaves the partition boundaries not matching the on disk limits of the file system. For a move to the left this leaves the partition reported as unknown, apparently losing the user's data. For example start with a 512 MiB partition containing an XFS file system. This is recognised by blkid and parted, hence also by GParted. # blkid /dev/sdb1 /dev/sdb1: UUID=... TYPE="xfs" PARTUUID="37965980-01" # parted /dev/sdb unit s print Model: ATA VBOX HARDDISK (scsi) Disk /dev/sdb: 16777216s Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags 1 1048576s 2097151s 1048576s primary xfs Now move the partition 100 MiB to the left and have it fail to inform the kernel after the first partition change step. Operation details: Move /dev/sdb1 to the left (ERROR) * calibrate /dev/sdb1 (SUCCESS) * check file system on /dev/sdb1 for errors and (if poss...(SUCCESS) * grow partition from 512.00 MiB to 612.00 MiB (ERROR) old start: 1048576 old end: 2097151 old size: 1048576 (512.00 MiB) requested start: 843776 requested end: 2097151 requested size: 1253376 (612.00 MiB) * libparted messages (ERROR) Error informing the kernel about modifications to partition /dev/sdb1 -- Device or resource busy. This means Linux won't know about any changes you made to /dev/sdb1 until you reboot -- so you shouldn't mount it or use it in any way before rebooting. Failed to add partition 1 (resource temporarily unavailable) Now because the start of the partition is 100 MiB before the start of the file system, the file system is no longer recognised, and apparently the user's data has been lost. # blkid /dev/sdb1 /dev/sdb1: PARTUUID="37965980-01" # parted /dev/sdb unit s print ... Number Start End Size Type File system Flags 1 843776s 2097151s 1253376s primary It doesn't matter why updating the partition failed, even if it was because of an error writing to the disk. Rollback of the change to the partition should be attempted. The worst case scenario is that rollback of the change fails, which is the equivalent to how the code worked before this patch set. However in other cases where the partition boundaries are being updated after a file system move or shrink step then the partition should be updated to match the new location of the file system itself. And no rollback is wanted. If the failure was only informing the kernel then in fact the partition has actually been updated on disk after all. So each partition resize/move step needs examining on a case by case basis to decide if rolling back the change to the partition is wanted or not. This patch only adds partition change rollback into resize_move_partition(). Rollback remains disabled until all cases are examined in the following patch.

Enable failed partition change rollback for selected steps (#791875) The general rule is that: 1) For a partition change step BEFORE a file system change step, rollback on failure; 2) For a partition change step AFTER a file system change step, don't rollback on failure. Examining every case where resize_move_partition() is called and whether rollback on failure is wanted or not: * In resize_move() Resize / move extended partition. No associated file system change. NO ROLLBACK Just to keep possibly applied operation. * #1 in move() Making all encompassing partition before moving file system. ROLLBACK To restore partition boundaries back to those of the file system. * #2 in move() Recreating original partition boundaries after file system move failed or was cancelled and has been rolled back. NO ROLLBACK To keep updated partition boundaries to match restored file system data. * #3 in move() Replacing all encompassing partition with final partition after successful file system move. NO ROLLBACK Keep new partition boundaries to match moved file system. * #1 in resize_encryption() Making the partition larger before growing closed LUKS encrypted data. ROLLBACK Restore partition boundaries back to those of the closed LUKS encrypted data. * #2 in resize_encryption() Shrinking the partition after open LUKS mapping has been shrunk, but before swap is re-created (smaller). NO ROLLBACK Difficult case because the partition shrink is in the middle of a LUKS shrink and a swap shrink (re-create). If swap was actually shrunk like other types of file system, rather than re-created, then the operation sequence would be (1) shrink swap, (2) shrink LUKS encryption, (3) shrink partition. In this hypothetical case and the actual case no rollback is preferred to try to keep the new partition boundaries match the shrunk open LUKS encryption mapping. * #3 in resize_encryption() Grow the partition before growing open LUKS mapping and re-creating swap larger. ROLLBACK Restore partition boundaries back to those of the smaller open LUKS encryption mapping. * #4 in resize_encryption() Shrink the partition after shrinking the file system and open LUKS encryption mapping. NO ROLLBACK Keep new smaller partition boundaries to match shrunk encrypted file system. * #5 in resize_encryption() Grow the partition before growing the open LUKS encryption mapping and file system. ROLLBACK Restore partition boundaries back to those of the not yet grown encrypted file system. * #1 in resize_plain() Resize partition before re-creating swap a different size. ROLLBACK Restore partition boundaries back to those of the not yet resized (re-created) swap space. * #2 in resize_plain() Shrink partition after shrinking the file system. NO ROLLBACK Keep new smaller partition boundaries to match shrunk file system. * #3 in resize_plain() Grow partition before growing the file system. ROLLBACK Restore partition boundaries back to those of the not yet grown file system.

Also as this is a create step, erase the partition first to prevent the possibility of any other file system signatures being found afterwards.

Implement maximize encryption volume as part of check repair operation (#774818) Now that resizing of encrypted file systems is implemented add growing of the open LUKS mapping as part of the check repair operation. Resizing an encrypted file system requires the LUKS mapping to be open to access the file system within; therefore it also requires libparted and kernel support for online partition resizing. This limits resizing to the latest distributions with libparted >= 3.2 and kernel >= 3.6. However growing an open LUKS mapping as part of a check repair operation doesn't require resizing the partition. Therefore route via offline grow of LUKS to avoid those extra, unnecessary requirement. This does mean that offline LUKS grow artificially requires cryptsetup, but that is not really significant as even opening LUKS requires cryptsetup. So now checking an encrypted file system on even the oldest distributions does: 1) runs FSCK on the encrypted file system; 2) grows the encryption volume to fill the partition; 3) grows the file system to fill the encryption mapping.

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

Remove coding landmine in get_disk() (#152) get_disk() is the wrapper around libparted's ped_disk_new() which reads a disk label from the specified device and if successful creates the in memory PedDisk object to represent it. In the case that libparted doesn't recognise a disk label or a file system, having get_disk() go and destroy the passed in PedDevice object via parameter lp_device is very unexpected behaviour hence describing it as a coding landmine. BACKGROUND 1. Early on GParted only worked with devices with valid disk labels. FileSystem.h:open_device_and_disk() required both ped_device_get() and ped_disk_new() to succeed or neither to succeed. 2. Commit [1] added support for devices which didn't yet have a disk label. open_device_and_disk() had default parameter strict=true added. While scanning strict=false was passed which allowed open_device_and_disk() to return success if only ped_device_get() succeeded and ped_disk_new() failed when the disk was empty. All other times open_device_and_disk() was called with default strict=true, still requiring both or neither to succeed. 3. Commit [2] added support for whole disk file systems. The now named get_device_and_disk() had it's functionality split between get_device() and get_disk(). This result in the code landmine being left behind: get_disk() destroying the passed device object if default parameter strict=true and no disk label or file system was detected. ANALYSIS 1. Since support for whole disk file systems [2] all current calls to get_device_and_disk() let the strict parameter default to true and are only called on known partitions within disk labels when applying a change to that partition. Therefore they don't care about the behaviour of get_disk(), just that get_device_and_disk() maintains that both ped_device_get() and ped_disk_new() succeed or neither succeed. 2. Two direct calls to get_disk() where the strict parameter defaults to true, from calibrate_partition() and erase_filesystem_signatures(), only do so on known partitions within disk labels as part of applying a change to that partition. Therefore ped_disk_new() will succeed and so PedDevice isn't deleted when not wanted. 3. The two remaining direct calls to get_disk() where the strict parameter is explicitly set to false, from set_device_from_disk() and detect_filesystem_in_encryption_mapping(), are when scanning. As the pass strict=false they don't allow the PedDevice deletion to occur if no recognised disk label is found. FIX Remove the strict parameter from get_disk() and get_device_and_disk() as it's no longer needed. Remove the code landmine by removing the side affect of destroying the PedDevice object if a disk label isn't found. Make sure get_device_and_disk() maintains the all or nothing behaviour. Also don't pass lp_device by reference to a pointer to get_disk() so the code can't change where lp_device points.

Split FILESYSTEMS and FILESYSTEM_MAP into separate module (!49) GParted_Core::FILESYSTEMS and ::FILESYSTEM_MAP and the methods that query and manipulate them are self-contained. Therefore move them into a separate SupportedFileSystems module.
