(Wayne Davison) + * Lower memory use and more optimal transfer of data over + the socket (see the INTERNAL section for details). - * Length of csum2 is now per-file starting with protocol verison - 27. (J.W. Schultz) + * The RSYNC_PROXY environment variable can now contain a + "USER:PASS@" prefix before the "HOST:PORT" information. + (Bardur Arantsson) - * Per-file dynamic block size is now sqrt(file length). - The per-file checksum size is determined according - to an algorythm 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 --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. - BUG FIXES: - - * 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 versios and - multiple files of the same name are destined for the same dir. - (Wayne Davison) - - * Keep tmp names from overflowing MAXPATHLEN. - - INTERNAL: - - * Eliminated vestigial support for old versions that we stopped - supporting. (J.W. Schultz) - - * Simplified some of the option-parsing code. (Wayne Davison) + * 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. -NEWS for rsync version 2.5.6, aka the dwd-between-jobs release -Protocol: 26 (unchanged) -Changes since version 2.5.5: - - ENHANCEMENTS: + BUG FIXES: - * The --delete-after option now implies --delete. (Wayne Davison) + * 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 --suffix option can now be used with --backup-dir. (Michael - Zimmerman) + * 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. - * 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) + * 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. - * The rsync:// syntax for daemon connections is now accepted in the - destination field. + * Fixed a byte-order problem in --batch-mode on big-endian + machines. (Jay Fenlason) - * If the file name given to --include-from or --exclude-from is "-", - rsync will read from standard input. (J.W. Schultz) + * Fixed configure bug when running "./configure --disable-ipv6". - * New option --link-dest which is like --compare-dest except that - unchanged files are hard-linked in to the destination directory. - (J.W. Schultz) + * Fixed "make test" bug when build dir is not the source dir. - * Don't report an error if an excluded file disappears during an - rsync run. (Eugene Chupriyanov and Bo Kersey) + * 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). - * Added .svn to --cvs-exclude list to support subversion. (Jon - Middleton) + * 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. - * Properly support IPv6 addresses in the rsyncd.conf "hosts allow" - and "hosts deny" fields. (Hideaki Yoshifuji) + * 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). - * Changed exclude file handling to permit DOS or MAC style line - terminations. (J.W. Schultz) + * 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. - * Ignore errors from chmod when -p/-a/--preserve-perms is not set. - (Dave Dykstra) + * Fixed the "refuse options" setting in the rsyncd.conf file. - BUG FIXES: + * 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 remaped + mount of the original filesystem could get discovered on a + disk we should be ignoring. - * Fix "forward name lookup failed" errors on AIX 4.3.3. (John - L. Allen, Martin Pool) + * 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). - * 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 compilation problem on Tru64 Unix (having to do with + sockaddr.sa_len and sockaddr.sin_len). - * Fix compilation on Tru64. (Albert Chin, Zoong Pham) + INTERNAL: - * Better handling of some client-server errors. (Martin Pool) + * Most of the I/O is now buffered, which results in a pretty + large speedup when running under MS Windows. (Craig Barratt) - * 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) + * Optimizations to the name-handling/comparing code have made + some significant reductions in user-CPU time for large file + sets. - * Fixed the file-name duplicate-removal code when dealing with multiple - dups in a row. (Wayne Davison) + * Some variable-type cleanup that makes the code more consistent. - * 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) + * Reduced memory requirements of hard link preservation. + (J.W. Schultz) - * Fixed bug in --copy-unsafe-links that caused it to be completely - broken. (Dave Dykstra) + * Implemented a new algorithm for hard-link handling that speeds + up the code significantly. (J.W. Schultz and Wayne Davison) - * Prevent infinite recursion in cleanup code under certain circumstances. - (Sviatoslav Sviridov and Marc Espie) + * 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. - * Fixed a bug that prevented rsync from creating intervening directories - when --relative-paths/-R is set. (Craig Barratt) + * 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) - * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara) + * More optimal data transmission for --hard-links (protocol 28). - INTERNAL: + * More optimal data transmission for --checksum (protocol 28). - * Many code cleanups and improved internal documentation. (Martin - Pool, Nelson Beebe) + * Less memory is used when --checksum is specified. - * Portability fixes. (Dave Dykstra and Wayne Davison) + * Less memory is used in the file list (a per-file savings). - * More test cases. (Martin Pool) + * 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) - * Some test-case fixes. (Brian Poole, Wayne Davison) + * 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). - * Updated included popt to the latest vendor drop, version 1.6.4. - (Jos Backus) + * 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. - * Updated config.guess and config.sub to latest versions; this - means rsync should build on more platforms. (Paul Green) + * Improved the internal uid/gid code to be more portable and + a little more optimized.
