There is a lot of commonality and code repetition for resizing of file
systems which can only be resized while mounted. Resizing of btrfs, jfs
and xfs all follow the pattern: mkdir, mount, resize, umount and rmdir.
Copying an xfs file system also uses a similar pattern, but for the
source and destination xfs file systems simultaneously.
Add three helper functions to the FileSystem class which implement
common tasks, allowing mounted file system resizing to be implemented
more simply.
Also add a function to the Utils class which checks whether the kernel
supports a file system. It handles the case of non-loaded modules,
which currently leads to reporting the growing of jfs and xfs as
unsupported.
Requires libparted 2.4 or higher, or blkid from utils-linux 2.20 or
higher for nilfs2 file system detection.
Requires nilfs-utils for nilfs2 file system support.
Closes Bug #642842 - nilfs is not detected
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
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.
Remove commented code and boolean use-C-lang parameter for
Utils::num_to_str() method because this bug was fixed in
gcc-4.0.3. The GNU gcc compiler versions 4 and up are now
commonly in use. Also due to previous partial commenting and
removal of the code, the code was non-functional
Thanks goes to Jan Claeys for pointing out this clean up
opportunity.
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)
* include/Utils.h,
src/Utils.cc: added format_time()
* include/OperationDetail.h,
src/OperationDetail.cc: keep track of elapsed time between
STATUS_EXECUTE and STATUS_[ERROR|SUCCES]
* include/Dialog_Progress.h,
src/Dialog_Progress.cc: show elapsed time in the details per (sub)
process
* src/GParted_Core.cc: use Utils::format_time()
* 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 ;)
* include/DrawingAreaVisualDisk.h,
src/DrawingAreaVisualDisk.cc: fixed a few issues with
selecting/activating partitions.
* include/Utils.h,
src/Utils.cc,
src/Dialog_Disklabel.cc,
src/Dialog_Partition_Info.cc (mk_label): improved support for
aligment.
* src/Win_GParted.cc: fixed a small alignmentissue in the devices
submenu.
* 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.
* implemented Utils::sector_to_unit() and use it in several places
* (finally) fixed errors with ntfsresizing (had a lot to do with
difference between MB and MiB)
* resizing of reiserfs now shows more detailed feedback
* support for TebiByte (TiB) unit
* include/Partition.h,
src/Partition.cc: added get_length()
* include/Utils.h,
src/Utils.cc,
src/Dialog_Partition_Info.cc,
src/Operation.cc,
src/TreeView_Detail.cc,
src/VBox_VisualDisk.cc,
src/Win_GParted.cc: from now on values >=1024MB are displayed in
GB's (#319840)
* include/Utils.h,
src/Utils.cc: added get_color_as_pixbuf() to create colored squares
of custom sizes. These can be use troughout the app to represent
filesystems. e.g. in the treeview and convertmenu.
* include/TreeView_Detail.h,
src/TreeView_Detail.cc,
include/VBox_VisualDisk.h,
src/VBox_VisualDisk.cc,
include/Win_GParted.h,
src/Win_GParted.cc: use Utils::get_color_as_pixbuf() instead of
custom drawn widgets.
* include/Utils.h,
src/Utils.cc: added mount() and unmount()
* src/Win_GParted.cc,
src/jfs.cc,
src/xfs.cc: use Utils::mount and Utils::umount instead of wrapping
CLI tools.
* replaced the inline Utils functions with static functions.
This shaves a few kbytes (24 in fact) off the binary and is a bit
cleaner code-wise (imho).
* 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...
* compose/ucompose.hpp: quick 'fix' for crashers in some locales (#157871)
* include/Utils.h: basicly the same + minor cleanups
* src/GParted_Core.cc: replaced C-style cast with static_cast..
* include/Utils.h: used static_cast<> instead of C-style type conversion.
* src/Makefile.am: install gparted binary in bin/ instead of sbin/ (as soon as i've time i want to implement a read-only modus)
* Added support for reiser4 (only creation atm, since the other functionality appears to be non-free software :/ )
Also, libparted isn't able to detect reiser4 yet, a patch to fix this is underway, but i should probably add reiser4 detection to gparted as well.
* src/GParted_Core.cc,
src/Win_GParted.cc,
include/Utils.h,
include/GParted_Core.h: moved inline Get_FS from Utils.h to GParted_Core, saves a few K in exe size ;)
* Refined checks for functionality a bit. e.g. even if a filesystem can't be read, it's still possible to grow it
(but shrinking gets disabled). Also removed that stupid grow_only flag from Utils.h and reordered Win_GParted::Set_Valid_Operations()
* added support for jfs (create, copy, grow) and hfs (create, copy)
* fixed a bug in copying xfs filesystems.
* fixed a number of small bugs/annoying issues.
* Added support for xfs. this means creating and growing xfs filesystems. Shrinking requires some hacking with dump_xfs etc..
i'll add that at a later point. :)
* 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.
* added MIN and MAX to filesystemstruct to set min. and max sizes of a filesystem. So instead of checking per filesystem
i now simply check the fs.MIN or fs.MAX. this results in less and cleaner code. Also this will come in handy when adding
support for new filesystems. (This also fixed several minor bugs with filesystemsizes and gained some improvement in resizer
performance)
* include/Utils.h,
src/GParted_Core.cc,
src/Partition.cc,
src/TreeView_Detail.cc,
src/VBox_VisualDisk.cc: marked some strings for translation ('unknown', 'used', 'unused') and replaced lowercase 'unallocated' with '---'.
* 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 =)
* instead of listing all partition in one list, logical partitions are now stored in a sublist in extended partition object.
This makes partitionhandling in gparted more natural and transparant. It also allowed me to clean up this ugly Operation class ;)
* configure.in: added checks for libuuid and libdl. Also refined libparted check a bit.
* include/Partition.h,
src/Partition.cc: removed Get_Color()
* include/Utils.h: added inline Glib::ustring Get_Color( const Glib::ustring & filesystem )
* src/Dialog_Partition_New.cc,
src/Win_GParted.cc: make use of Get_Color from Utils.h
* src/Device.cc: fixed a crasher with (at least) pl_PL locale.
