See the + --human-readable option for a way to turn it off. See also the daemon's + "log format" parameter and related command-line options (including + --out-format) for a modifier that can be used to request digit-grouping + or human-readable output in log escapes. (Note that log output is + unchanged by default.) When some level of human-readable output is + enabled, the column width for the file size in the --list-only output + is increased. + + - The output of the --progress option has changed: the string "xfer" was + shortened to "xfr", and the string "to-check" was shortened to "to-chk", + both designed to make room for the (by default) wider display of file + size numbers without making the total line-length longer. Also, when + incremental recursion is enabled, the string "ir-chk" will be used + instead of "to-chk" up until the incremental-recursion scan is done, + letting you know that the value to check and the total value will still + be increasing as new files are found. + + - Enhanced the --stats output: 1) to mention how many files were created + (protocol >= 28), 2) to mention how many files were deleted (new for + protocol 31, but only output when --delete is in effect), and 3) to + follow the file-count, created-count, and deleted-count with a subcount + list broken down by type. + + BUG FIXES: + + - Changed the way --progress overwrites its prior output in order to make + it nearly impossible for the progress to get overwritten by an error. + + - Fixed some rare bugs in --iconv processing that might cause a multibyte + character to get translated incorrectly. + + - Improved the propagation of abnormal-exit error messages. This should + help the client side to receive errors from the server when it is exiting + abnormally, and should also avoid dying with an "connection unexpectedly + closed" exit when the closed connection is really expected. ENHANCEMENTS: - * Lower memory use and more optimal transfer of data over - the socket (see the INTERNAL section for details). + - Added the --remote-option=OPT (-M OPT) command-line option that is useful + for things like sending a remote --log-file=FILE or --fake-super option. - * The RSYNC_PROXY environment variable can now contain a - "USER:PASS@" prefix before the "HOST:PORT" information. - (Bardur Arantsson) + - Added the --info=FLAGS and --debug=FLAGS options to allow finer-grained + control over what is output. Added an extra type of --progress output + using --info=progress2. - * 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. + - The --msgs2stderr option can help with debugging rsync by allowing the + debug messages to get output to stderr rather than travel via the socket + protocol. - * The configure script now accepts --with-rsyncd-conf=PATH - to override the default value of the /etc/rsyncd.conf file. + - Added the --delete-missing-args and --ignore-missing-args options to + either delete or ignore user-specified files on the receiver that are + missing on the sender (normally the absence of user-specified files + generates an error). - * Added a couple extra diffs in the "patches" dir, removed the - ones that got applied, and rebuilt the rest. + - Added a "T" (terabyte) category to the --human-readable size suffixes. - BUG FIXES: + - Added the --usermap/--groupmap/--chown options for manipulating file + ownership during the copy. - * When -x (--one-file-system) is combined with -L (--copy-links) - or --copy-unsafe-links, no symlinked files are skipped, even - if the referent file is on a different filesystem. - - * 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 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. - - * Fixed a byte-order problem in --batch-mode on big-endian - machines. (Jay Fenlason) - - * Fixed configure bug when running "./configure --disable-ipv6". - - * 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). The - items are also now properly word-split and parsed without - any +/- prefix munging. - - * 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. - - * Fixed the "refuse options" setting in the rsyncd.conf file. - - * 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 remapped - mount of the original filesystem could get discovered in a - subdir we should be ignoring. - - * 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). - - * Path-specifying options to a daemon should now work the same with - or without chroot turned on. Previously, such a option (such as - --link-dest) would get its absolute path munged into a relative - one if chroot was not on, making that setting fairly useless. - Rsync now transforms the path into one that is based on the - module's base dir when chroot is not enabled. - - * Fixed compilation problem on Tru64 Unix (having to do with - sockaddr.sa_len and sockaddr.sin_len). - - * Fixed a compatibility problem interacting with older rsync - versions that might send us an empty --suffix value without - telling us that --backup-dir was specified. - - * The "hosts allow" option for a daemon-over-remote-shell - process now has improved support for IPv6 addresses and a fix - for systems that have a length field in their socket structs. - - * Fixed the ability to request an empty backup --suffix when - sending files to an rsync daemon. + - Added the "%C" escape to the log-output handling, which will output the + MD5 checksum of any transferred file, or all files if --checksum was + specified (when protocol 30 or above is in effect). - INTERNAL: + - Added the "reverse lookup" parameter to the rsync daemon config file to + allow reverse-DNS lookups to be disabled. + + - Added a way for more than one group to be specified in the daemon's + config file, including a way to specify that you want all of the + specified user's groups without having to name them. Also changed the + daemon to complain about an inability to set explicitly-specified uid/gid + values, even when not run by a super-user. + + - Added a way to reference environment variables in a daemon's config file + (using %VAR% references). - * Most of the I/O is now buffered, which results in a pretty - large speedup when running under MS Windows. (Craig Barratt) + - When replacing a non-dir with a symlink/hard-link/device/special-file, + the update should now be done in an atomic manner. - * Optimizations to the name-handling/comparing code have made - some significant reductions in user-CPU time for large file - sets. + - Fixed a free of the wrong pointer in uncache_tmp_xattrs() (which only + sometimes affects an --xattr transfer when --backup is used). - * Some variable-type cleanup that makes the code more consistent. + - When backing up a file, try to hard-link the file into place so that the + upcoming replacement of the destination file will be atomic. - * Reduced memory requirements of hard link preservation. - (J.W. Schultz) + - Added the ability to synchronize nano-second modified times. - * Implemented a new algorithm for hard-link handling that speeds - up the code significantly. (J.W. Schultz and Wayne Davison) + - Added a few more default suffixes for the "dont compress" settings. - * 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. + - Added the checking of the RSYNC_PROTECT_ARGS environment variable to allow + the default for the --protect-args command-line option to be overridden. - * 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 some Solaris xattr code. - * More optimal data transmission for --hard-links (protocol 28). + EXTRAS: - * More optimal data transmission for --checksum (protocol 28). + - Added an "instant-rsyncd" script to the support directory, which makes + it easy to configure a simple rsync daemon in the current directory. + + - Added the "mapfrom" and "mapto" scripts to the support directory, which + makes it easier to do user/group mapping in a local transfer based on + passwd/group files from another machine. + + INTERNAL: - * Less memory is used when --checksum is specified. + - The I/O code was rewritten to be simpler and do bigger buffered reads + over the socket. The I/O between the receiver and the generator was + changed to be standard multiplexed-I/O (like that over the socket). - * Less memory is used in the file list (a per-file savings). + - The sender tries to use any dead time while the generator is looking for + files to transfer in order to do sender-side directory scanning in a more + parallel manner. - * 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. + - A daemon can now inform a client about a daemon-configured timeout value + so that the client can assist in the keep-alive activity (protocol 31). - * Changed hardlink info and file_struct + strings to use - allocation pools. This reduces memory use for large file- - sets and permits freeing memory to the OS. (J.W. Schultz) + - The filter code received some refactoring to make it more extendable, to + read better, and do better sanity checking. - * 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). + - Really big numbers are now output using our own big-num routine rather + than casting them to a double and using a %.0f conversion. - * 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. + - The pool_alloc library has received some minor improvements in alignment + handling. - * Improved the internal uid/gid code to be more portable and - a little more optimized. + - Added init_stat_x() function to avoid duplication of acl/xattr init code. - * The device numbers sent when using --devices are now sent as - separate major/minor values with 32-bit accuracy (protocol 28). - Previously, the copied devices were sent as a single 32-bit - number. This will make inter-operation of 64-bit binaries more - compatible with their 32-bit brethren. Note that optimizations - in the binary protocol often sends the device data using fewer - bytes than before, even though more precision is now available. + DEVELOPER RELATED: - * Some cleanup of the exclude/include structures and its code - made things clearer, simpler, and more efficient. + - Added more conditional debug output.
