E2fsprogs 1.40 release imminent!

The hg repository located at:

http://thunk.org/hg/e2fsprogs

... contains what I hope to be the e2fsprogs 1.40 release. If folks could test it and let me know if they find any embarassing bugs, I would greatly appreciate it. It can also be found at:

ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/e2fsprogs/e2fsprogs-1.40-rc1.tar.gz

Over the next few days, I'll be working on converting e2fsprogs SCM from hg to git. Assuming no one finds any problems, I'll be releasing e2fsprogs 1.40 by the end of the week.

Regards,

The release at the URL above seems to solve the issues I've been seeing on ARM (in particular, it seems to fix the strict aliasing issue that was causing dumpe2fs to segfault.)

Thanks!

What about undo I/O manager ?

This I/O manager saves the contents of the location being overwritten to a tdb database. This helps in undoing the changes done to the file system.

The call sequence involve

set_undo_io_backing_manager(unix_io_manager);
set_undo_io_backup_file("/tmp/test.tdb");
retval = ext2fs_open2(dev_name, 0, flags,

		superblock, block_size, undo_io_manager,
		&current_fs);

The patch is on top of e2fsprogs-upstream mercurial repo

That and many other queued patches will be merged after 1.40 releases. I didn't want to include anything that would be high risk or wouldn't be useful as standalone. The undo manager by itself isn't going to be useful until it's integrated into other e2fsprogs programs, and I didn't want to put off the 1.40 release. So for the past couple of weeks I've only been merging bug fixes so we could do a stable release.

There are a bunch of patches applied in the gentoo package that might be worth looking at:
http://dev.gentoo.org/~hanno/e2fsprogs/

All of them still seem to apply to the current mercurial source. I'm not really familiar with them, just noted that there are a lot of patches and nobody seemed to care sending upstream in the past.

Thanks, none of these are critical. I'll go through them and apply them after the 1.40 release.

e2fsprogs-1.39-util-strptime.patch was fixed in another way in my sources.
