P) It still needs a lot of love, but the foundations are laid =) * 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 =)

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.

Add helper functions for mounted file system resizing operations 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.

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.

Instead glibmm just tried to change to the directory with a zero length name. This was fixed with glibmm >= 2.21.2 released July 2009, however RHEL / CentOS 5.9 only has glibmm 2.12.10.

Add helper functions for mounted file system resizing operations 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.

Fix mismatched field precision type compiler warning Inserted cast to int so that third parameter matches expected parameter precision type. Original warning: FileSystem.cc: In member function ‘Glib::ustring GParted::FileSystem::mk_temp_dir(const Glib::ustring&, GParted::OperationDetail&)’: FileSystem.cc:81:69: warning: field precision should have type ‘int’, but argument 3 has type ‘long unsigned int’

P) It still needs a lot of love, but the foundations are laid =) * 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 =)
