-rsync release candidate 2.5.5rc1 (26 March 2002)
+NEWS for rsync 2.6.1 (UNRELEASED)
+Protocol: 27 (unchanged)
+Changes since 2.6.0:
ENHANCEMENTS:
- * With --progress, when a transfer is complete show the time taken;
- otherwise show expected time to complete. (Cameron Simpson)
+ * Lower memory use and more optimal transfer of data over
+ the socket (see the INTERNAL section for details).
- * Make "make install-strip" works properly, and "make install"
- accepts a DESTDIR variable for help in building binary packages.
- (Peter Breitenlohner, Greg Louis)
+ * 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're processed.
BUG FIXES:
- * Fix situation where failure to fork (e.g. because out of process
- slots) would cause rsync to kill all processes owned by the
- current user. Yes, really! (Paul Haas, Martin Pool)
+ * 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)
- * Fix test suite on Solaris. (Jos Backus)
+ * 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)
- * Fix minor memory leak in socket code. (Dave Dykstra, Martin
- Pool.)
+ * Fixed a byte-order problem in --batch-mode on big-endian
+ machines. (Jay Fenlason)
- * Fix --whole-file problem that caused it to be the default even
- for remote connections. (Martin Pool, Frank Schulz)
+ * Fixed configure bug when running "./configure --disable-ipv6".
+ (Wayne Davison)
- * Work around bug in Mac OS X mkdir(2), which cannot handle
- trailing slashes.
- <http://www.opensource.apple.com/bugs/X/BSD%20Kernel/2734739.html>
- (Martin Pool)
+ * 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).
+
+ 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)
+
+ * Some variable-type cleanup that makes the code more consistent.
+ (Wayne Davison)
+
+ * 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.
+
+ * 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).
+
+ * 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 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).

+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:
+
+ * 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)
+
+ * Fixed a bug in the --backup code that could cause deleted files
+ to not get backed up.
+
+ * 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).
+
+ * Call setgroups() in a more portable manner.
+
+ * Improved file-related error messages to better indicate exactly
+ what pathname failed. (Wayne Davison)
+
+ * Fixed some bugs in the handling of --delete and --exclude when
+ using the --relative (-R) option. (Wayne Davison)
+
+ * 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)
+
+ * 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)
+
+ * 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:
+
+ * Eliminated vestigial support for old versions that we stopped
+ supporting. (J.W. Schultz)
+
+ * Simplified some of the option-parsing code. (Wayne Davison)
+
+ * Some cleanup made to the exclude code, as well as some new
+ defines added to enhance readability. (Wayne Davison)
+
+ * 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)
