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.) + + - The --list-only option is now affected by the --human-readable setting. + It will display digit groupings by default, and unit suffixes if higher + levels of readability are requested. Also, the column width for the size + output has increased from 11 to 14 characters when human readability is + enabled. Use --no-h to get the old-style output and column size. + + - 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 (a new line + 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 that shows the counts by type. The wording of the transferred count + has also changed so that it is clearer that it is only a count of regular + files. BUG FIXES: - * 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). - - 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) + - Changed the way --progress overwrites its prior output in order to make + it nearly impossible for the progress to get overwritten by an error. - * Reduced memory requirements of hard link preservation. - (J.W. Schultz) + - Fixed some rare bugs in --iconv processing that might cause a multibyte + character to get translated incorrectly. - * 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: + - 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: - * "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) + - 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 --stats option no longer includes the (debug) malloc summary - unless the verbose option was specified at least twice. + - 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. - * 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. + - 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. - * Various trailing-info sections are now preceded by a newline. + - 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). - 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) + - Added a "T" (terabyte) category to the --human-readable size suffixes. - - 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.] + - Added the --usermap/--groupmap/--chown options for manipulating file + ownership during the copy. - - "**/foo" now matches at the base of the transfer (like /foo - does). [Use "/**/foo" to get the old behavior in all versions.] + - 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). - - 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.] + - Added the "reverse lookup" parameter to the rsync daemon config file to + allow reverse-DNS lookups to be disabled. - - 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.] + - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can + be disabled via "forward lookup" parameter (defaults to enabled). - * 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) + - 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. - * 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) + - Added per-user authorization options and group-authorization support to + the daemon's "auth users" parameter. - * 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) + - Added a way to reference environment variables in a daemon's config file + (using %VAR% references). - * 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) + - When replacing a non-dir with a symlink/hard-link/device/special-file, + the update should now be done in an atomic manner. - * Keep tmp names from overflowing MAXPATHLEN. + - Fixed a free of the wrong pointer in uncache_tmp_xattrs() (which only + sometimes affects an --xattr transfer when --backup is used). - * Make --link-dest honor the absence of -p, -o, and -g. + - 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. - * Made rsync treat a trailing slash in the destination in a more - consistent manner. + - Added the ability to synchronize nano-second modified times. - * Fixed file I/O error detection. (John Van Essen) + - Added a few more default suffixes for the "dont compress" settings. - * 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. + - Added the checking of the RSYNC_PROTECT_ARGS environment variable to allow + the default for the --protect-args command-line option to be overridden. - * Print heap statistics when verbose >= 2 instead of when >= 1. + - Added some Solaris xattr code. - * Fixed a compression (-z) bug when syncing a mostly-matching file - that contains already-compressed data. (Yasuoka Masahiko and - Wayne Davison) + EXTRAS: - * Fixed a bug in the --backup code that could cause deleted files - to not get backed up. + - Added an "instant-rsyncd" script to the support directory, which makes + it easy to configure a simple rsync daemon in the current directory. - * 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). + - 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. - * Call setgroups() in a more portable manner. + INTERNAL: - * Improved file-related error messages to better indicate exactly - what pathname failed. (Wayne Davison) + - 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). - * Fixed some bugs in the handling of --delete and --exclude when - using the --relative (-R) option. (Wayne Davison) + - 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. - * 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) + - 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). - * 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) + - The filter code received some refactoring to make it more extendable, to + read better, and do better sanity checking. - * Added a fix that should give ssh time to restore the tty settings - if the user presses Ctrl-C at an ssh password prompt. + - Really big numbers are now output using our own big-num routine rather + than casting them to a double and using a %.0f conversion. - INTERNAL: + - The pool_alloc library has received some minor improvements in alignment + handling. - * Eliminated vestigial support for old versions that we stopped - supporting. (J.W. Schultz) + - Added init_stat_x() function to avoid duplication of acl/xattr init code. - * Simplified some of the option-parsing code. (Wayne Davison) + DEVELOPER RELATED: - * Some cleanup made to the exclude code, as well as some new - defines added to enhance readability. (Wayne Davison) + - Added more conditional debug output. - * 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) + - Changed configure.in to configure.ac.
