(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) + + * 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: + + * 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) + + * 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). + + * 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) - * Fix compilation on Tru64. (Albert Chin, Zoong Pham) + * 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) - * Better handling of some client-server errors. (Martin Pool) + * 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) - * When -e is specified along with an rsyncd url, the client should - get a warning but it should not be treated as an error. (Bill - Nottingham) + * 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) - http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=62489 + * 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: - * Many code cleanups and improved internal documentation. (Martin - Pool, Nelson Beebe) + * Eliminated vestigial support for old versions that we stopped + supporting. (J.W. Schultz) + + * 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) + * 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)
