(Wayne Davison) - - * Length of csum2 is now per-file starting with protocol verison - 27. (J.W. Schultz) - - * 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 --stats option no longer includes the (debug) malloc summary - unless the verbose option was specified at least twice. +NEWS for rsync 3.1.0 (UNRELEASED) +Protocol: 31 (changed) +Changes since 3.0.4: + + OUTPUT CHANGES: + + - Output numbers in 3-digit groups by default (e.g. 1,234,567). 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: - * 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. - - - "**/foo" now matches at the base of the transfer (i.e. /foo). - - - An 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. - - - 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" (for instance). - - * 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) - - * 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 versions and - multiple files of the same name are destined for the same dir. - (Wayne Davison) - - * 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) + - 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 a compression (-z) bug when syncing a mostly-matching file - that contains already-compressed data. (Yasuoka Masahiko and - Wayne Davison) + - Fixed some rare bugs in --iconv processing that might cause a multibyte + character to get translated incorrectly. - * Fixed a bug in the --backup code that could cause deleted files - to not get backed up. - - * 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) - - INTERNAL: - - * Eliminated vestigial support for old versions that we stopped - supporting. (J.W. Schultz) - - * Simplified some of the option-parsing code. (Wayne Davison) - - * 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) - - -NEWS for rsync version 2.5.6, aka the dwd-between-jobs release -Protocol: 26 (unchanged) -Changes since version 2.5.5: + - 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: - * The --delete-after option now implies --delete. (Wayne Davison) + - 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 --suffix option can now be used with --backup-dir. (Michael - Zimmerman) + - 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. - * 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) + - 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 rsync:// syntax for daemon connections is now accepted in the - destination field. + - 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). - * If the file name given to --include-from or --exclude-from is "-", - rsync will read from standard input. (J.W. Schultz) + - Added a "T" (terabyte) category to the --human-readable size suffixes. - * New option --link-dest which is like --compare-dest except that - unchanged files are hard-linked in to the destination directory. - (J.W. Schultz) + - Added the --usermap/--groupmap/--chown options for manipulating file + ownership during the copy. - * Don't report an error if an excluded file disappears during an - rsync run. (Eugene Chupriyanov and Bo Kersey) + - 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). - * Added .svn to --cvs-exclude list to support subversion. (Jon - Middleton) + - Added the "reverse lookup" parameter to the rsync daemon config file to + allow reverse-DNS lookups to be disabled. - * Properly support IPv6 addresses in the rsyncd.conf "hosts allow" - and "hosts deny" fields. (Hideaki Yoshifuji) + - 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. - * Changed exclude file handling to permit DOS or MAC style line - terminations. (J.W. Schultz) + - Added a way to reference environment variables in a daemon's config file + (using %VAR% references). - * Ignore errors from chmod when -p/-a/--preserve-perms is not set. - (Dave Dykstra) + - When replacing a non-dir with a symlink/hard-link/device/special-file, + the update should now be done in an atomic manner. - BUG FIXES: + - Fixed a free of the wrong pointer in uncache_tmp_xattrs() (which only + sometimes affects an --xattr transfer when --backup is used). + + - 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. - * Fix "forward name lookup failed" errors on AIX 4.3.3. (John - L. Allen, Martin Pool) + - Added the ability to synchronize nano-second modified times. - * 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) + - Added a few more default suffixes for the "dont compress" settings. - * Fix compilation on Tru64. (Albert Chin, Zoong Pham) + - Added the checking of the RSYNC_PROTECT_ARGS environment variable to allow + the default for the --protect-args command-line option to be overridden. - * Better handling of some client-server errors. (Martin Pool) + - Added some Solaris xattr code. - * 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) + EXTRAS: - * Fixed the file-name duplicate-removal code when dealing with multiple - dups in a row. (Wayne Davison) + - Added an "instant-rsyncd" script to the support directory, which makes + it easy to configure a simple rsync daemon in the current directory. - * 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) + - 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. - * Fixed bug in --copy-unsafe-links that caused it to be completely - broken. (Dave Dykstra) + INTERNAL: - * Prevent infinite recursion in cleanup code under certain circumstances. - (Sviatoslav Sviridov and Marc Espie) + - 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 a bug that prevented rsync from creating intervening directories - when --relative-paths/-R is set. (Craig Barratt) + - 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. - * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara) + - 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). - INTERNAL: + - The filter code received some refactoring to make it more extendable, to + read better, and do better sanity checking. - * Many code cleanups and improved internal documentation. (Martin - Pool, Nelson Beebe) + - Really big numbers are now output using our own big-num routine rather + than casting them to a double and using a %.0f conversion. - * Portability fixes. (Dave Dykstra and Wayne Davison) + - The pool_alloc library has received some minor improvements in alignment + handling. - * More test cases. (Martin Pool) + - Added init_stat_x() function to avoid duplication of acl/xattr init code. - * Some test-case fixes. (Brian Poole, Wayne Davison) + DEVELOPER RELATED: - * Updated included popt to the latest vendor drop, version 1.6.4. - (Jos Backus) + - Added more conditional debug output. - * Updated config.guess and config.sub to latest versions; this - means rsync should build on more platforms. (Paul Green) + - Changed configure.in to configure.ac.
