Rdiff-backup

Restore of archives made by 0.10.x and earlier fixed, although hard link information is not restored unless it is current in the mirror.
(Bug reported by Jeff Lessem.)

Fixed problem with door files locally when repository is remote.
(Reported by Robert Weber.)

Patch by Jeffrey Marshall fixes socket/fifo recognition on Mac OS X (which apparently has buggy macros).

Patch by Jeffrey Marshall fixes --calculate-average mode, which seems to have broken recently.

rdiff-backup should now work and build with python 2.3.
Thanks to Arkadiusz Miskiewicz and Arkadiusz Patyk for bug reports and a patch.

rdiff-backup now builds and requires librsync 0.9.6.
This version should be much better than the old one and everyone should probably upgrade.
Much thanks to Donovan Baarda for all the work that went into this release.

To prevent the buildup of confusing and error-prone options, the capabilities of the source and destination file systems are now autodetected.
Detected features include allowed characters, extended attributes, access control lists, hard links, ownership, and directory fsyncing.
Options such as --windows-mode, --chars-to-quote, --quoting-char, and --windows-restore-mode have been removed.

Now rdiff-backup supports user extended attributes (EAs).
To take advantage of this you will need the python module pyxattr and a file system that supports EAs.
Thanks to Greg Freemyer for valuable discussion.

Support for access control lists (ACLs) was also added.
An ACL capable file system and the python package pylibacl (which exports the posix1e module) are required.
Thanks to Greg Freemyer for valuable discussion.

Thanks to patches by Daniel Hazelbaker, rdiff-backup now reads and writes Mac OS X style resource forks!

**** Warning **** The above features are new to this development release, and it is difficult to test all the possibly combinations of source and destination file systems.
They should not be considered stable.
However, help would be appreciated testing these new features.

**** Warning 2 **** rdiff-backup records ACL and EA information in files designed to be compatible with the utilities "getfacl" and "getfattr".
However, there is a possible security hole in both these formats (see http://acl.bestbits.at/pipermail/acl-devel/2003-June/001498.html).
rdiff-backup's format will be fixed when getf{attr|acl}'s is.

Added --list-increment-sizes switch, which tells you how much space the various backup files take up.
(Suggested by Andrew Bressen)

Although it should be detected automatically, can avoid copying permissions to directory increments with --no-change-dir-inc-perms.
(Problem on FreeBSD when backing up sticky directories reported by Troels Arvin.)

Fixed bug with --check-destination and --windows-mode reported by Tucker Sylvestro.

The librsync blocksize is now chosen based on filesize.
This should make operations on large files faster (in some cases, orders of magnitude faster).
Thanks to Ty!
Boyack for bringing this issue to my attention.

Fixed (?) bug that caused crash when file changes type from regular file in middle of download (reported by Ty!
Boyack).

Failure to construct regular file in regression/restoration only causes warning, not fatal error.

Removed --exclude-mirror option.
(Probably no one uses this, and it adds clutter.)

--include and --exclude options should work now with restores, with some speed penalty.

Added EDEADLOCK to the list of skippable errors.
(Thanks to Dave Kempe for report.)

Added --list-at-time option at request of Farkas Levente.

Various fixes for backing up onto windows directories.
Thanks to Keith Edmunds for bug reports and testing.

Fixed possible crash when a file would be deleted while being processed (reported by Robert Weber).

Handle better cases when there are two files with the same name in the same directory.

Added --windows-restore switch, for use when when restoring from a windows-style file system to a normal one.
Use --windows-mode when backing up.

Scott Bender's patch fixes backing up hard links when first linked file is quoted.

Fixed bug incrementing sockets whose filenames were pretty long, but not super long.
Reported by Olivier Mueller.

Added Albert Chin-A-Young's patch to add a few options to the setup.py install script.

Apparently fixed rare utime type bug.
Thanks to Christian Skarby for report and testing.

Added detailed file_statistics (in addition to session_statistics) as requested by Dean Gaudet.
Disable with --no-file-statistics option.

Minor speed enhancements.

Fixed a number of bugs reported by Olivier Mueller:

....
Brought some old parts of the man page up-to-date.

Fixed bug if unrecoverable error on second backup to a directory.

Fixed spurious error message that could appear after a successful
backup.

--print-statistics option works again (before it would silently
ignored).

Fixed cache pipeline overflow bug. This error could appear on
large remote backups when many files have not changed.
