NEWS for rsync 2.6.1 (UNRELEASED)
NEWS for rsync 2.6.1 (26 Apr 2004)
Protocol: 28 (changed)
Changes since 2.6.0:
SECURITY FIXES:
- Paths sent to an rsync daemon are more thoroughly sanitized when
chroot is not used. If you're running a non-read-only rsync
daemon with chroot disabled, *please upgrade*, ESPECIALLY if the
user privs you run rsync under is anything above "nobody".
ENHANCEMENTS:
* Lower memory use and more optimal transfer of data over
the socket (see the INTERNAL section for details).
- Lower memory use, more optimal transfer of data over the socket,
and lower CPU usage (see the INTERNAL section for details).

- The RSYNC_PROXY environment variable can now contain a
"USER:PASS@" prefix before the "HOST:PORT" information.
(Bardur Arantsson)
* The --progress output now mentions how far along in the
transfer we are, including both a count of files transferred
and a percentage of the total file-count that we've processed.
It also shows better current-rate-of-transfer and remaining-
transfer-time values.

BUG FIXES:
* When -x (--one-file-system) is combined with -L (--copy-links)
or --copy-unsafe-links, no symlinked files are skipped, even
if the referent file is on a different filesystem.

* The --link-dest code now works properly for a non-root user
when (1) the UIDs of the source and destination differ and -o
was specified, or (2) when the group of the source can't be
used on the destination and -g was specified.

cause the expanded PATH/NAME value of the current item to
get overwritten (due to an expanded-name caching bug).

* We now reset the "new data has been sent" flag at the start
of each file we send. This makes sure that an interrupted
transfer with the --partial option set doesn't keep a shorter
temp file than the current basis file when no new data has been
transfered over the wire for that file.

* When using --cvs-exclude, the exclude items we get from a

directory (and not all following directories too). The
items are also now properly word-split and parsed without
any +/- prefix munging.

per-directory's .cvsignore file once again only affect that one

* When specifying the USER@HOST: prefix for a file, the USER
part can now contain an '@', if needed (i.e. the last '@'
is used to find the HOST, not the first).

* Fixed some bugs in the handling of group IDs for non-root
users: (1) It properly handles a group that the sender didn't
have a name for (it would previously skip changing the group
on any files in that group). (2) If --numeric-ids is used,
rsync no longer attempts to set groups that the user doesn't
have the permission to set.

* Improved the -x (--one-file-system) flag's handling of any
mount-point directories we encounter. It is both more optimal
(in that it no longer does a useless scan of the contents of
the mount-point dirs) and also fixes a bug where a remapped
mount of the original filesystem could get discovered in a
subdir we should be ignoring.

- Rsync no longer discards a double-slash at the start of a filename
when trying to open the file. It also no longer constructs names
that start with a double slash (unless the user supplied them).
* Path-specifying options to a daemon should now work the same with
- Path-specifying options to a daemon should now work the same with
or without chroot turned on. Previously, such a option (such as
--link-dest) would get its absolute path munged into a relative
one if chroot was not on, making that setting fairly useless.
Rsync now transforms the path into one that is based on the
module's base dir when chroot is not enabled.
* Fixed compilation problem on Tru64 Unix (having to do with
- Fixed compilation problem on Tru64 Unix (having to do with
sockaddr.sa_len and sockaddr.sin_len).
* Fixed a compatibility problem interacting with older rsync
- Fixed a compatibility problem interacting with older rsync
versions that might send us an empty --suffix value without
telling us that --backup-dir was specified.
* The "hosts allow" option for a daemon-over-remote-shell
process now has improved support for IPv6 addresses and a fix
for systems that have a length field in their socket structs.

- The --hard-link option now uses the first existing file in the
group of linked files as the basis for the transfer. This
prevents the sub-optimal transfer of a file's data when a new
hardlink is added on the sending side and it sorts alphabetically
earlier in the list than the files that are already present on the
receiving side.

(2.3.0 released 15 Mar 1999) and activated warnings for
protocols less than 25 (2.5.0 released 23 Aug 2001)

* The 2 pipes used between the receiver and generator processes
(which are forked on the same machine) were reduced to 1 pipe
and the protocol improved so that (1) it is now impossible to
have the "redo" pipe fill up and hang rsync, and (2) trailing
messages from the receiver don't get lost on their way through
the generator over to the sender (the latter mainly affected
hard-link messages and verbose --stats output).

- The device numbers sent when using --devices are now sent as
separate major/minor values with 32-bit accuracy (protocol 28).
Previously, the copied devices were sent as a single 32-bit
number. This will make inter-operation of 64-bit binaries more
compatible with their 32-bit brethren. Note that optimizations
in the binary protocol often sends the device data using fewer
bytes than before, even though more precision is now available.
