-rsync changes since last release
+NEWS for rsync 2.6.1 (UNRELEASED)
+Protocol: 27 (unchanged)
+Changes since 2.6.0:
ENHANCEMENTS:
- * The --delete-after option now implies --delete. (Wayne Davison)
+ * Lower memory use and more optimal transfer of data over
+ the socket (see the INTERNAL section for details).
- * The --suffix option can now be used with --backup-dir. (Michael
- Zimmerman)
+ * The RSYNC_PROXY environment variable can now contain a
+ "USER:PASS@" prefix before the "HOST:PORT" information.
+ (Bardur Arantsson)
- * 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)
+ * 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're processed.
- * The rsync:// syntax for daemon connections is now accepted in the
- destination field.
+ 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 referant file is on a different filesystem.
+
+ * The --link-dest code now works properly for a non-root user
+ when the UIDs of the source and destination differ and -o was
+ specified, and when the group of the source can't be used on
+ the destination and -g was specified. (Wayne Davison)
+
+ * 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).
+ (Wayne Davison)
+
+ * 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. (Wayne Davison)
+
+ * Fixed a byte-order problem in --batch-mode on big-endian
+ machines. (Jay Fenlason)
+
+ * Fixed configure bug when running "./configure --disable-ipv6".
+ (Wayne Davison)
+
+ * 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).
+
+ * When transferring a file that has group 0 with -g specified
+ (typically via -a) and not enough privs to retain the group,
+ rsync no longer complains about "chown" failing.
+
+ * 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.
+
+ INTERNAL:
+
+ * 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. (Wayne Davison)
- * If the file name given to --include-from or --exclude-from is "-",
- rsync will read from standard input. (J.W. Schultz)
+ * Some variable-type cleanup that makes the code more consistent.
+ (Wayne Davison)
- * New option --link-dest which is like --compare-dest except that
- unchanged files are hard-linked in to the destination directory.
+ * Reduced memory requirements of hard link preservation.
(J.W. Schultz)
- * Don't report an error if an excluded file disappears during an
- rsync run. (Eugene Chupriyanov and Bo Kersey)
+ * 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.
+
+ * Got rid of support for protocol versions 17 and 18 (which are
+ both over 6 years old). (Wayne Davison)
+
+ * More optimal data transmission for --hard-links (protocol 28).
- * Added .svn to --cvs-exclude list to support subversion. (Jon
- Middleton)
+ * More optimal data transmission for --checksum (protocol 28).
- * Properly support IPv6 addresses in the rsyncd.conf "hosts allow"
- and "hosts deny" fields. (Hideaki Yoshifuji)
+ * Less memory is used when --checksum is specified.
- * Set the default value of --modify-window to 2 on Cygwin. (Lapo
- Luchini)
+ * Less memory is used in the file list (a per-file savings).
- * Ignore errors from chmod when -p/-a/--preserve-perms is not set.
- (Dave Dykstra)
+ * Changed hardlink info and file_struct + strings to use
+ allocation pools. This reduces memory use for large
+ filesets 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). (Wayne Davison)
+
+ * 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.
+
+ * Optimized the -x (--one-file-system) flag's handling of any
+ mount-point directories we encounter (it no longer scans the
+ contents of the mount-point dirs, just to throw away the data).
+
+ * Improved the internal uid/gid code to be more portable and
+ a little more optimized.

+NEWS for rsync 2.6.0 (1 Jan 2004)
+Protocol: 27 (changed)
+Changes since 2.5.7:
+
+ ENHANCEMENTS:
+
+ * "ssh" is now the default remote shell for rsync. If you want to
+ change this, configure like this: "./configure --with-rsh=rsh".
+
+ * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
+ Note that --from0 affects the line-ending character for all the
+ files read by the --*-from options. (Wayne Davison)
+
+ * Length of csum2 is now per-file starting with protocol version
+ 27. (J.W. Schultz)
+
+ * Per-file dynamic block size is now sqrt(file length). The
+ per-file checksum size is determined according to an algorithm
+ provided by Donovan Baarda which reduces the probability of rsync
+ algorithm corrupting data and falling back using the whole md4
+ checksums. (J.W. Schultz, Donovan Baarda)
+
+ * The --stats option no longer includes the (debug) malloc summary
+ unless the verbose option was specified at least twice.
+
+ * Added a new error/warning code for when files vanish from the
+ sending side. Made vanished source files not interfere with the
+ file-deletion pass when --delete-after was specified.
+
+ * Various trailing-info sections are now preceded by a newline.
BUG FIXES:
-
- * Fix "forward name lookup failed" errors on AIX 4.3.3. (John
- L. Allen, Martin Pool)
- * 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)
+ * Fixed several exclude/include matching bugs when using wild-cards.
+ This has a several user-visible effects, all of which make the
+ matching more consistent and intuitive. This should hopefully not
+ cause anyone problems since it makes the matching work more like
+ what people are expecting. (Wayne Davison)
+
+ - A pattern with a "**" no longer causes a "*" to match slashes.
+ For example, with "/*/foo/**", "foo" must be 2 levels deep.
+ [If your string has BOTH "*" and "**" wildcards, changing the
+ "*" wildcards to "**" will provide the old behavior in all
+ versions.]
+
+ - "**/foo" now matches at the base of the transfer (like /foo
+ does). [Use "/**/foo" to get the old behavior in all versions.]
+
+ - A non-anchored wildcard term floats to match beyond the base of
+ the transfer. E.g. "CVS/R*" matches at the end of the path,
+ just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
+ to get the old behavior in all versions.]
+
+ - Including a "**" in the match term causes it to be matched
+ against the entire path, not just the name portion, even if
+ there aren't any interior slashes in the term. E.g. "foo**bar"
+ would exclude "/path/foo-bar" (just like before) as well as
+ "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
+ old behavior in all versions.]
+
+ * The exclude list specified in the daemon's config file is now
+ properly applied to the pulled items no matter how deep the
+ user's file-args are in the source tree. (Wayne Davison)
+
+ * For protocol version >= 27, mdfour_tail() is called when the
+ block size (including checksum_seed) is a multiple of 64.
+ Previously it was not called, giving the wrong MD4 checksum.
+ (Craig Barratt)
+
+ * For protocol version >= 27, a 64 bit bit counter is used in
+ mdfour.c as required by the RFC. Previously only a 32 bit bit
+ counter was used, causing incorrect MD4 file checksums for
+ file sizes >= 512MB - 4. (Craig Barratt)
+
+ * Fixed a crash bug when interacting with older rsync versions and
+ multiple files of the same name are destined for the same dir.
+ (Wayne Davison)
+
+ * Keep tmp names from overflowing MAXPATHLEN.
+
+ * Make --link-dest honor the absence of -p, -o, and -g.
+
+ * Made rsync treat a trailing slash in the destination in a more
+ consistent manner.
+
+ * Fixed file I/O error detection. (John Van Essen)
+
+ * Fixed bogus "malformed address {hostname}" message in rsyncd log
+ when checking IP address against hostnames from "hosts allow"
+ and "hosts deny" parameters in config file.
+
+ * Print heap statistics when verbose >= 2 instead of when >= 1.
+
+ * Fixed a compression (-z) bug when syncing a mostly-matching file
+ that contains already-compressed data. (Yasuoka Masahiko and
+ Wayne Davison)
- * Fix compilation on Tru64. (Albert Chin, Zoong Pham)
+ * Fixed a bug in the --backup code that could cause deleted files
+ to not get backed up.
- * Better handling of some client-server errors. (Martin Pool)
+ * When the backup code makes new directories, create them with mode
+ 0700 instead of 0755 (since the directory permissions in the
+ backup tree are not yet copied from the main tree).
- * 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)
+ * Call setgroups() in a more portable manner.
- * Fixed the file-name duplicate-removal code when dealing with multiple
- dups in a row. (Wayne Davison)
+ * Improved file-related error messages to better indicate exactly
+ what pathname failed. (Wayne Davison)
- * 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)
+ * Fixed some bugs in the handling of --delete and --exclude when
+ using the --relative (-R) option. (Wayne Davison)
- * Fixed bug in --copy-unsafe-links that caused it to be completely
- broken. (Dave Dykstra)
+ * Fixed bug that prevented regular files from replacing
+ special files and caused a directory in --link-dest or
+ --compare-dest to block the creation of a file with the
+ same path. A directory still cannot be replaced by a
+ regular file unless --delete specified. (J.W. Schultz)
- * Prevent infinite recursion in cleanup code under certain circumstances.
- (Sviatoslav Sviridov)
+ * Detect and report when open or opendir succeed but read and
+ readdir fail caused by network filesystem issues and truncated
+ files. (David Norwood, Michael Brown, J.W. Schultz)
- * Fixed a bug that prevented rsync from creating intervening directories
- when --relative-paths/-R is set. (Craig Barratt)
+ * Added a fix that should give ssh time to restore the tty settings
+ if the user presses Ctrl-C at an ssh password prompt.
INTERNAL:
- * Many code cleanups and improved internal documentation. (Martin
- Pool, Nelson Beebe)
+ * Eliminated vestigial support for old versions that we stopped
+ supporting. (J.W. Schultz)
- * Portability fixes. (Dave Dykstra and Wayne Davison)
+ * Simplified some of the option-parsing code. (Wayne Davison)
- * More test cases. (Martin Pool)
+ * Some cleanup made to the exclude code, as well as some new
+ defines added to enhance readability. (Wayne Davison)
- * Updated included popt to the latest vendor drop, version 1.6.4.
- (Jos Backus)
+ * Changed the protocol-version code so that it can interact at a
+ lower protocol level than the maximum supported by both sides.
+ Added an undocumented option, --protocol=N, to force the value
+ we advertise to the other side (primarily for testing purposes).
+ (Wayne Davison)
