-rsync changes since last release
+NEWS for rsync 2.6.1 (UNRELEASED)
+Protocol: 28 (changed)
+Changes since 2.6.0:
+
+ ENHANCEMENTS:
+
+ * Lower memory use and more optimal transfer of data over
+ the socket (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.
+
+ * The configure script now accepts --with-rsyncd-conf=PATH
+ to override the default value of the /etc/rsyncd.conf file.
+
+ * Added a couple extra diffs in the "patches" dir, removed the
+ ones that got applied, and rebuilt the rest.
BUG FIXES:
-
- * Fix "forward name lookup failed" errors on AIX 4.3.3. (John
- L. Allen, Martin Pool)
- * Fix compilation on Tru64. (Albert Chin, Zoong Pham)
+ * 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.
+
+ * Fixed a bug in the handling of -H (hard-links) that might
+ 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.
+
+ * Fixed a byte-order problem in --batch-mode on big-endian
+ machines. (Jay Fenlason)
+
+ * Fixed configure bug when running "./configure --disable-ipv6".
+
+ * Fixed "make test" bug when build dir is not the source dir.
+
+ * When using --cvs-exclude, the exclude items we get from a
+ directory's .cvsignore file once again only affect that one
+ directory (and not all following directories too). The
+ items are also now properly word-split and parsed without
+ any +/- prefix munging.
+
+ * 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.
+
+ * Fixed the "refuse options" setting in the rsyncd.conf file.
+
+ * 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
+ 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.
- * Better handling of some client-server errors. (Martin Pool)
+ * 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
+ 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.
+
+ * Fixed the ability to request an empty backup --suffix when
+ sending files to an rsync daemon.
INTERNAL:
- * Many code cleanups and improved internal documentation. (Martin
- Pool, Nelson Beebe)
+ * Most of the I/O is now buffered, which results in a pretty
+ large speedup when running under MS Windows. (Craig Barratt)
+
+ * Optimizations to the name-handling/comparing code have made
+ some significant reductions in user-CPU time for large file
+ sets.
+
+ * Some variable-type cleanup that makes the code more consistent.
+
+ * Reduced memory requirements of hard link preservation.
+ (J.W. Schultz)
+
+ * Implemented a new algorithm for hard-link handling that speeds
+ up the code significantly. (J.W. Schultz and Wayne Davison)
+
+ * 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.
+
+ * Dropped support for protocol versions less than 20
+ (2.3.0 released 15 Mar 1999) and activated warnings for
+ protocols less than 25 (2.5.0 released 23 Aug 2001)
+ (Wayne Davison and J.W. Schultz, severally)
+
+ * More optimal data transmission for --hard-links (protocol 28).
+
+ * More optimal data transmission for --checksum (protocol 28).
+
+ * Less memory is used when --checksum is specified.
+
+ * Less memory is used in the file list (a per-file savings).
+
+ * The generator is now better about not modifying the file list
+ during the transfer in order to avoid a copy-on-write memory
+ bifurcation (on systems where fork() uses shared memory).
+ Previously, rsync's shared memory would slowly become unshared,
+ resulting in real memory usage nearly doubling on the receiving
+ side by the end of the transfer. Now, as long as permissions
+ are being preserved, the shared memory should remain that way
+ for the entire transfer.
+
+ * Changed hardlink info and file_struct + strings to use
+ allocation pools. This reduces memory use for large file-
+ sets and permits freeing memory to the OS. (J.W. Schultz)
+
+ * 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 reading & writing of the file-list in batch-mode is now
+ handled by the same code that sends & receives the list over
+ the wire. This makes it much easier to maintain.
+
+ * Improved the internal uid/gid code to be more portable and
+ a little more optimized.
- * More test cases. (Martin Pool)
+ * 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.
+ * Some cleanup of the exclude/include structures and its code
+ made things clearer, simpler, and more efficient.
