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
This reason for refactoring is to simplify the large GParted_Core
class, to help minimize disk reads, and to group the logic for
processing the file /proc/partitions into a single logical class.
Make align to MiB the default setting instead of align to cylinder.
Migrate logic for alignment to cylinder into its own method
snap_to_cylinder, and place common logic in snap_to_alignment.
Add alignment checks for situations where space is needed for Master
Boot Record or Extended Boot Record.
Adjust ranges on spin buttons according to required boot record space.
Copy fix for off by one sector (#596552) from
Dialog_Partition_New::Get_New_Partition to
Dialog_Base_Partition::Get_New_Partition
Enhance resize / move logic for checking locations of nearby logical
partitions to not depend on the partition ordering.
Note: This commit does not include limiting graphic movement according
to required boot record space.
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)
* src/Dialog_Progress.cc: make sure progressfraction stays between 0.0
and 1.0
* include/GParted_Core.h,
src/GParted_Core.cc: implemented rollback in case of failed move of
overlapping filesystems. Together with the readonly test moving
should be quite save now :)
* include/GParted_Core.h,
src/GParted_Core.cc: declared char * buf global, so it can be
initialized in copy_blocks(). This is a lot more efficient than
initializing it on every copy_block()
* include/Partition.h,
src/Partition.cc: added test_overlap()
* include/GParted_Core.h,
src/GParted_Core.cc: perform a readonly testrun before the actual
move if destination overlaps source.
* include/GParted_Core.h,
src/GParted_Core.cc: update ntfsbootsector after first sector has
changed. This is necessary to let windows boot correctly afterwards.
* src/ntfs.cc: added FIXME
* include/GParted_Core.h,
src/GParted_Core.cc: tried to fix a couple of errors with moving to
the right with overlap (thanks Larry for hunting ;) )
Although everything seems to work well i'm still not sure if
everything is 100% ok.
I guess everything could use some more testing, which is exactly
what i plan to do this weekend :)
* happy 24th birthday Johannes! :^)
* include/GParted_Core.h,
src/GParted_Core.cc: restructured resize_move() to be more robust.
This will hopefully tackle a couple of issues which came up during
the public testing.
* include/GParted_Core.h,
src/GParted_Core.cc: fixed some issues with combi move+shrink on
fat* and hfs* filesystems.
Also call wait_for_node() from commit() if 'node' was provided.
* include/GParted_Core.h,
src/GParted_Core.cc: created set_progress_info() (i actually planned
on adding some time remaining stuff, but xfiles is waiting ;) )
* include/GParted_Core.h,
src/GParted_Core.cc: did some work on disabling of automounting of
removable drives. The current method is not entirely to my liking
but it seems to work.
* implemented some stuff to find a good blocksize to use for
copy/move. Actually i'm not really happy with it, because probing
seems suboptimal, but it's better than nothing. As soon as i have
some time i should do some research on the subject to find a better
solution.
* include/FileSystem.h,
include/GParted_Core.h,
src/FileSystem.cc,
src/GParted_Core.cc,
src/ext2.cc,
src/ext3.cc,
src/ntfs.cc,
src/reiserfs.cc: removed cylindersize buffering during resize from
the filesystems. It is not needed anymore now we calculate the new
position before calling this.
Also added some extra progressfeedback in the core
* src/Win_GParted.cc: added FIXME:
* include/GParted_Core.h,
src/GParted_Core.cc,
src/fat32.cc: decoupled libparted partition and filesystemresizing.
This resulted in a much more consistent core. This also affected
several other aspects of resizing/moving in a positive way.
* include/GParted_Core.h,
src/GParted_Core.cc,
src/Win_GParted.cc: perform some checks before adding a new
operation to the list.
* src/Partition.cc: made get_length() a bit safer
* src/Win_GParted.cc,
include/GParted_Core.h,
src/GParted_Core.cc: implemented snap to cylinder algorithm.
Although the algorithm is very simple, it seems to work perfectly.
However, some additional testing is required.
* include/GParted_Core.h,
src/GParted_Core.cc,
src/ext2.cc: added movesupport, atm in experimental state and needs
lots of cleaning. only enabled for ext2, but should work for all
filesystems.
* src/DialogFeatures.cc: added alternating rowcolours (see #342682)
