-NEWS for rsync version 2.5.6, aka the dwd-between-jobs release
-Changes since version 2.5.5:
+NEWS for rsync 2.6.2 (UNRELEASED)
+Protocol: 28 (unchanged)
+Changes since 2.6.1:
- ENHANCEMENTS:
-
- * The --delete-after option now implies --delete. (Wayne Davison)
-
- * The --suffix option can now be used with --backup-dir. (Michael
- Zimmerman)
-
- * Combining "::" syntax with the -rsh/-e option now uses the
- specified remote-shell as a transport to talk to a (newly-spawned)
- server-daemon. This allows someone to use daemon features, such
- as modules, over a secure protocol, such as ssh. (JD Paul)
+ BUG FIXES:
- * The rsync:// syntax for daemon connections is now accepted in the
- destination field.
+ - Fixed a major bug in the sorting of the filenames when --relative
+ is used for some sources (probably just "/", but don't depend on
+ that). This fix ensures that we ask for the right file-list item
+ when requesting changes from the sender.
- * If the file name given to --include-from or --exclude-from is "-",
- rsync will read from standard input. (J.W. Schultz)
+ - Rsync now checks the return value of the close() function to
+ better report disk-full problems on an NFS file system.
- * New option --link-dest which is like --compare-dest except that
- unchanged files are hard-linked in to the destination directory.
- (J.W. Schultz)
+ - Restored the old daemon-server behavior of logging error messages
+ rather than returning them to the user. (A better long-term fix
+ will be sought in the future.)
- * Don't report an error if an excluded file disappears during an
- rsync run. (Eugene Chupriyanov and Bo Kersey)
+ - An obscure uninitialized-variable bug was fixed in the uid/gid
+ code. (This bug probably had no ill effects.)
- * Added .svn to --cvs-exclude list to support subversion. (Jon
- Middleton)
+ - Got rid of the configure check for sys/sysctl.h (it wasn't used
+ and was causing a problem on some systems).
- * Properly support IPv6 addresses in the rsyncd.conf "hosts allow"
- and "hosts deny" fields. (Hideaki Yoshifuji)
+ ENHANCEMENTS:
- * Changed exclude file handling to permit DOS or MAC style line
- terminations. (J.W. Schultz)
+ - Two new diffs were added to the patches dir.
- * Ignore errors from chmod when -p/-a/--preserve-perms is not set.
- (Dave Dykstra)

+NEWS for rsync 2.6.1 (26 Apr 2004)
+Protocol: 28 (changed)
+Changes since 2.6.0:
- BUG FIXES:
-
- * Fix "forward name lookup failed" errors on AIX 4.3.3. (John
- L. Allen, Martin Pool)
+ SECURITY FIXES:
- * Generate each file's rolling-checksum data as we send it, not
- in a separate (memory-eating) pass before hand. This prevents
- timeout errors on really large files. (Stefan Nehlsen)
+ - 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".
- * Fix compilation on Tru64. (Albert Chin, Zoong Pham)
+ ENHANCEMENTS:
- * Better handling of some client-server errors. (Martin Pool)
+ - Lower memory use, more optimal transfer of data over the socket,
+ and lower CPU usage (see the INTERNAL section for details).
- * Fixed a crash that would occur when sending a list of files that
- contains a duplicate name (if it sorts to the end of the file
- list) and using --delete. (Wayne Davison)
+ - The RSYNC_PROXY environment variable can now contain a
+ "USER:PASS@" prefix before the "HOST:PORT" information.
+ (Bardur Arantsson)
- * Fixed the file-name duplicate-removal code when dealing with multiple
- dups in a row. (Wayne Davison)
+ - 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.
- * Fixed a bug that caused rsync to lose the exit status of its child
- processes and sometimes return an exit code of 0 instead of showing
- an error. (David R. Staples, Dave Dykstra)
+ - The configure script now accepts --with-rsyncd-conf=PATH to
+ override the default value of the /etc/rsyncd.conf file.
- * Fixed bug in --copy-unsafe-links that caused it to be completely
- broken. (Dave Dykstra)
+ - Added a couple extra diffs in the "patches" dir, removed the ones
+ that got applied, and rebuilt the rest.
- * Prevent infinite recursion in cleanup code under certain circumstances.
- (Sviatoslav Sviridov and Marc Espie)
+ - Documentation changes now attempt to describe some often mis-
+ understood features more clearly.
- * Fixed a bug that prevented rsync from creating intervening directories
- when --relative-paths/-R is set. (Craig Barratt)
+ BUG FIXES:
- * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara)
+ - 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
+ per-directory's .cvsignore file once again only affect that one
+ directory (not all following directories too). The items are also
+ now properly word-split and parsed without any +/- prefix parsing.
+
+ - 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.
+
+ - 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)
-
- * Portability fixes. (Dave Dykstra and Wayne Davison)
+ - Most of the I/O is now buffered, which results in a pretty large
+ speedup when running under MS Windows. (Craig Barratt)
- * More test cases. (Martin Pool)
+ - Optimizations to the name-handling/comparing code have made some
+ significant reductions in user-CPU time for large file sets.
- * Some test-case fixes. (Brian Poole, Wayne Davison)
+ - Some cleanup of the variable types make the code more consistent.
- * Updated included popt to the latest vendor drop, version 1.6.4.
- (Jos Backus)
+ - Reduced memory requirements of hard link preservation.
+ (J.W. Schultz)
- * Updated config.guess and config.sub to latest versions; this
- means rsync should build on more platforms. (Paul Green)
+ - 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 (which mainly affected hard-link messages and
+ verbose --stats output).
+
+ - Improved the internal uid/gid code to be more portable and a
+ little more optimized.
+
+ - 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 (with both ends of the
+ connection are using protocol 28). Note that optimizations in the
+ binary protocol for sending the device numbers often results in
+ fewer bytes being used than before, even though more precision is
+ now available.
+
+ - Some cleanup of the exclude/include structures and its code made
+ things clearer (internally), simpler, and more efficient.
+
+ - 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. (Note that the
+ batch code is still considered to be experimental.)
