This avoids unexpected behavior and should not adversely + affect most people. If you're one of those rare people who relied + upon having an implied dir be duplicated as a symlink, either specify + --keep-dirlinks or --no-implied-dirs. - * The RSYNC_PROXY environment variable can now contain a - "USER:PASS@" prefix before the "HOST:PORT" information. - (Bardur Arantsson) + BUG FIXES: - * 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 the output of -ii when combined with one of the --*-dest options: + it now itemizes all the items, not just the changed ones. - * The configure script now accepts --with-rsyncd-conf=PATH - to override the default value of the /etc/rsyncd.conf file. + - Made the output of all file types consistent when using a --*-dest + option. Prior versions used to output too many creation events for + matching items. - * Added a couple extra diffs in the "patches" dir, removed the - ones that got applied, and rebuilt the rest. + - The code that waits for a child pid now handles being interrupted by a + signal. This fixes a problem with the pre-xfer exec function not being + able to get the exit status from the script. - BUG FIXES: + - A negated filter rule (with a '!' modifier) no longer loses the negation + when sending the filter rules to the remote rsync. + + - Fixed a problem with the --out-format (aka --log-format) option %f: it + would output superfluous directory information for a non-daemon rsync. + + - Fixed a problem with -vv (double --verbose) and --stats when "pushing" + files (which includes local copies). Version 2.6.9 would complete the + copy, but exit with an error when the receiver output its memory stats. + + - If --password-file is used on a non-daemon transfer, rsync now complains + and exits. This should help users figure out that they can't use this + option to control a remote shell's password prompt. + + - Make sure that directory permissions of a newly-created destination + directory are handled right when --perms is left off. + + - The itemized output of a newly-created destination directory is now + output as a creation event, not a change event. + + - Improved --hard-link so that more corner cases are handled correctly + when combined with options such as --link-dest and/or --ignore-existing. - * 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 --append option no longer updates a file that has the same size. - * 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 when combining --backup and --backup-dir with --inplace: + any missing backup directories are now created. - * 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). + - Fixed a bug when using --backup and --inplace with --whole-file or + --read-batch: backup files are actually created now. + + - Starting up an extra copy of an rsync daemon does not delete the pidfile + for the running daemon -- if the pidfile exists, the extra program will + exit with an error. + + - The daemon pidfile is checked and created sooner in the startup sequence. + + ENHANCEMENTS: + + - A new incremental-recursion algorithm is now used when rsync is talking + to another 3.x version. This starts the transfer going more quickly + (before all the files have been found), and requires much less memory. + See the --recursive option in the manpage for some restrictions. + + - Saved memory in the non-incremental-recursion algorithm for typical + option values (usually saving from 21-29 bytes per file). + + - The default --delete algorithm is now --delete-during when talking to a + 3.x rsync. This is a faster scan than using --delete-before (which is + the default when talking to older rsync versions), and is compatible with + the new incremental recursion mode. + + - Rsync now allows multiple remote-source args to be specified rather than + having to rely on a special space-splitting side-effect of the remote- + shell. Additional remote args must specify the same host or have an + empty hostname, as seen here: :file1 ::module/file2. This means that + local use of brace expansion now works: rsync -av host:path/{f1,f2} . + + - Added the --delete-delay option, which is a more efficient way to delete + files at the end of the transfer without needing a separate delete pass. + + - Added the --acls (-A) option to preserve Access Control Lists. This is + an improved version of the prior patch that was available, and it even + supports OS X ACLs. (If you need to have backward compatibility with + old, patched versions of rsync, apply the acls.diff file from the patches + dir.) + + - Added the --xattrs (-X) option to preserver extended attributes. This is + an improved version of the prior patch that was available. (If you need + to have backward compatibility with old, patched versions of rsync, apply + the xattrs.diff file from the patches dir.) + + - Added the --fake-super option that allows a non-super user to preserve + all attributes of a file by using a special extended-attribute idiom. + There is also an analogous "fake super" option for an rsync daemon. + + - Added the --iconv option, which allows rsync to convert filenames from + one character-set to another during the transfer. The default is to make + this feature available as long as your system has iconv_open(). If + compilation fails, specify --disable-iconv to configure, and then + rebuild. If you want rsync to perform character-set conversions by + default, you can specify --enable-iconv=CONVERT_STRING with the default + value for the --iconv option that you wish to use. For example, + --enable-iconv=. is a good choice. See the rsync manpage for an + explanation of the --iconv option's settings. + + - Added the --skip-compress=LIST option to override of the default list of + file suffixes that will not be compressed when using --compress. - * 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 daemon's default for "dont compress" was extended to include: + *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg + The matching routine was also optimized to run more quickly. + + - The --max-delete option now outputs a warning if it skipped any file + deletions, including a count of how many deletions were skipped. (Older + versions just silently stopped deleting things.) + + - You may specify --max-delete=0 to a 3.0.0 client to request that it warn + about extraneous files without deleting anything. If you're not sure + what version the client is, you can use the less-obvious --max-delete=-1, + as both old and new versions will treat that as the same request (though + older versions don't warn). + + - The --hard-link option now uses less memory on both the sending and + receiving side for all protocol versions. For protocol 30, the use of a + hashtable on the sending side allows us to more efficiently convey to the + receiver what files are linked together. This reduces the amount of data + sent over the socket by a considerable margin (rather than adding more + data), and limits the in-memory storage of the device+inode information + to just the sending side for the new protocol 30, or to the receiving + side when speaking an older protocol (note that older rsync versions kept + the device+inode information on both sides). - * Fixed a byte-order problem in --batch-mode on big-endian - machines. (Jay Fenlason) + - The filter rules now support a perishable ("p") modifier that marks rules + that should not have an effect in a directory that is being deleted. e.g. + -f '-p .svn/' would only affect "live" .svn directories. - * Fixed configure bug when running "./configure --disable-ipv6". + - If we get an error setting the time on a symlink, we don't complain about + it anymore (since some operating systems don't support that, and it's not + that important). - * Fixed "make test" bug when build dir is not the source dir. + - Protocol 30 now uses MD5 checksums instead of MD4. - * 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). + - If a daemon module's "path" value is not an absolute pathname, the code + now makes it absolute internally (making it work properly). - * 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 the --append option to not checksum the existing data in the + destination file, which speeds up file appending. - * 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. + - Added the --append-verify option, which works like the older --append + option (verifying the existing data in the destination file). For + compatibility with older rsync versions, any use of --append that is + talking protocol 29 or older will revert to the --append-verify method. - * Fixed the "refuse options" setting in the rsyncd.conf file. + - Documented and extended the support for the RSYNC_CONNECT_PROG variable + that can be used to enhance the client side of a daemon connection. - * 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. + - Added the --protect-args (-s) option, that tells rsync to send most of + the command-line args at the start of the transfer rather than as args + to the remote-shell command. This protects them from space-splitting, + and only interprets basic wildcard special shell characters (*?[). - * 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). + - Improved the dashes and double-quotes in the nroff manpage output. - * Fixed compilation problem on Tru64 Unix (having to do with - sockaddr.sa_len and sockaddr.sin_len). + - We now support a lot more --no-OPTION override options. INTERNAL: - * Most of the I/O is now buffered, which results in a pretty - large speedup when running under MS Windows. (Craig Barratt) + - The file-list sorting algorithm now uses a sort that keeps any same- + named items in the same order as they were specified. This allows + rsync to always ensure that the first of the duplicates is the one + that will be included in the copy. The new sort was also faster + than the glibc version of qsort() and mergesort() in my testing. - * Optimizations to the name-handling/comparing code have made - some significant reductions in user-CPU time for large file - sets. + - Rsync now supports the transfer of 64-bit timestamps (time_t values). - * Some variable-type cleanup that makes the code more consistent. + - Fixed a build problem with older (2.x) versions of gcc. - * Reduced memory requirements of hard link preservation. - (J.W. Schultz) + - Added some isType() functions that make dealing with signed characters + easier without forcing variables via casts. - * Implemented a new algorithm for hard-link handling that speeds - up the code significantly. (J.W. Schultz and Wayne Davison) + - Changed strcat/strcpy/sprintf function calls to use safer versions. - * 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. + - Upgraded the included popt version to 1.10.2 and improved its use of + string-handling functions. - * 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) + - Added missing prototypes for compatibility functions from the lib dir. - * More optimal data transmission for --hard-links (protocol 28). + - Configure determines if iconv() has a const arg, allowing us to avoid a + compiler warning. - * More optimal data transmission for --checksum (protocol 28). + - Made the sending of some numbers more efficient for protocol 30. - * Less memory is used when --checksum is specified. + - Make sure that a daemon process doesn't mind if the client was weird and + omitted the --server option. - * Less memory is used in the file list (a per-file savings). + - Improved the use of "const" on pointers. - * 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. + - Improved J.W.'s pool_alloc routines to add a way of freeing older + sections of a pool's memory. - * 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) + DEVELOPER RELATED: - * 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). + - Rsync is now licensed under the GPLv3 or later. - * 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. + - When running the tests, we now put our per-test temp dirs into a sub- + directory named testtmp (which is created, if missing). This allows + someone to symlink the testtmp directory to another filesystem (which is + useful if the build dir's filesystem does not support ACLs and xattrs, + and another file system does). - * Improved the internal uid/gid code to be more portable and - a little more optimized. + - Rsync now has a way of handling protocol-version changes during the + development of a new protocol version. This exchange of sub-version + info does not interfere with the {MIN,MAX}_PROTOCOL_VERSION checking + in older versions (since we'd quickly exceed the MAX_PROTOCOL_VERSION + if we incremented the main PROTOCOL_VERSION value for every minor + change during development).
