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
On disks with an unrecognized disk label, the end sector value
was saved as one sector larger than actual. This caused the
Partition Information dialog to report the end sector value and
the total number of sectors on the disk as one larger than the
actual value.
Closes Bug #649444 - Partition information reports wrong sector
count
I hit this performance bug when I cloneda 40G NTFS partition. The actual
copy was done in under 11 minutes. After that I was shocked to find that
gparted would spend over 12 minutes in cleanup_cursor, pegging a CPU
core. (On a quad core desktop...)
Simply replacing the ustring with std::string would reduce the time to
about 1.5 minutes. Still bad. Also, I didn't want to lose UTF8
awareness.
So I rewrote the algorithm in 'streaming mode'. This has the (potential)
drawback that locale conversions are done, but performs well and
- IMHO - is a lot more readable.
On a minor note: this implementation correctly handles backspaces at the
start of a line.
Change spawn_command_line_sync to spawn_sync to reduce the level of
quoting required when passing commands to the function. Since
spawn_command_line_sync uses the parent's environment, the replacement
call also uses the parent's environment.
This change permits unmounting of file systems mounted with an
apostrophe in the mount point name.
