-Changes since 2.6.0:
+NEWS for rsync 3.0.0 (UNRELEASED)
+Protocol: 30 (changed)
+Changes since 2.6.9:
- ENHANCEMENTS:
+ NOTABLE CHANGES IN BEHAVIOR:
- * Lower memory use and more optimal transfer of data over
- the socket (see the INTERNAL section for details).
+ - The handling of implied directories when using --relative has changed to
+ send them as directories (e.g. no implied dir is ever sent as a symlink).
+ This avoids unexpected behavior and should not adversely affect most
+ people. If you're one of those rare individuals who relied upon having
+ an implied dir be duplicated as a symlink, you should specify the
+ transfer of the symlink and the transfer of the referent directory as
+ separate args. (See also --keep-dirlinks and --no-implied-dirs.)
- * The RSYNC_PROXY environment variable can now contain a
- "USER:PASS@" prefix before the "HOST:PORT" information.
- (Bardur Arantsson)
+ - Requesting a remote file list without specifying -r (--recursive) now
+ sends the -d (--dirs) option to the remote rsync rather than sending -r
+ along with an extra exclude of /*/*. If the remote rsync does not
+ understand the -d option (i.e. it is 2.6.3 or older), you will need to
+ either turn off -d (--no-d), or specify -r --exclude='/*/*' manually.
- * 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're processed.
+ - In --dry-run mode, the last line of the verbose summary text is output
+ with a "(DRY RUN)" suffix to help remind you that no updates were made.
BUG FIXES:
- * The --link-dest code now works properly for a non-root user
- when the UIDs of the source and destination differ and -u 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)
-
- * Keep per-file track of the sending of literal data with
- --partial so that an interrupted transfer doesn't keep a
- shorter temp file when no new data has been transfered over
- the wire. (Wayne Davison)
+ - Fixed the output of -ii when combined with one of the --*-dest options:
+ it now itemizes all the items, not just the changed ones.
- * Fixed a byte-order problem in --batch-mode on big-endian
- machines. (Jay Fenlason)
+ - Made the output of all file types consistent when using a --*-dest
+ option. Prior versions would output too many creation events for
+ matching items.
- * Fixed configure bug when running "./configure --disable-ipv6".
- (Wayne Davison)
+ - 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.
- * Fixed "make test" bug when build dir is not the source dir.
+ - A negated filter rule (i.e. with a '!' modifier) no longer loses the
+ negation when sending the filter rules to the remote rsync.
- * 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).
+ - Fixed a problem with the --out-format (aka --log-format) option %f: it
+ no longer outputs superfluous directory info for a non-daemon rsync.
- * 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.
+ - 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.
- * 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:
+ - 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.
- * Most of the I/O is now buffered, which results in a pretty
- large speedup when running under MS Windows. (Craig Barratt)
+ - Make sure that directory permissions of a newly-created destination
+ directory are handled right when --perms is left off.
- * Optimizations to the name-handling/comparing code have made
- some significant reductions in user-CPU time for large file
- sets. (Wayne Davison)
+ - The itemized output of a newly-created destination directory is now
+ output as a creation event, not a change event.
- * Some variable-type cleanup that makes the code more consistent.
- (Wayne Davison)
+ - Improved --hard-link so that more corner cases are handled correctly
+ when combined with options such as --link-dest and/or --ignore-existing.
- * Reduced memory requirements of hard link preservation.
- (J.W. Schultz)
+ - The --append option no longer updates a file that has the same size.
- * Implemented a new algorithm for hard-link handling that speeds
- up the code significantly. (J.W. Schultz and Wayne Davison)
+ - Fixed a bug when combining --backup and --backup-dir with --inplace:
+ any missing backup directories are now created.
- * Got rid of support for protocol versions 17 and 18 (which are
- both over 6 years old). (Wayne Davison)
+ - Fixed a bug when using --backup and --inplace with --whole-file or
+ --read-batch: backup files are actually created now.
- * More optimal data transmission for --hard-links (protocol 28).
+ - Starting up an extra copy of an rsync daemon will not clobber the pidfile
+ for the running daemon -- if the pidfile exists, the new daemon will exit
+ with an error.
- * More optimal data transmission for --checksum (protocol 28).
+ - The daemon pidfile is checked and created sooner in the startup sequence.
- * Less memory used for holding --checksum data.
+ - If a daemon module's "path" value is not an absolute pathname, the code
+ now makes it absolute internally (making it work properly).
- * Less memory used per-file in the file list.
+ - Ensure that a temporary file always has owner-write permission while we
+ are writing to it. This avoids problems with some network filesystems.
- * 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.

-NEWS for rsync 2.6.0 (1 Jan 2004)
-Protocol: 27 (changed)
-Changes since 2.5.7:
+ - Any errors output about password-file reading no longer cause an error at
+ the end of the run about a partial transfer.
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)
-
- * The --stats option no longer includes the (debug) malloc summary
- unless the verbose option was specified at least twice.
-
- * 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.
-
- * Various trailing-info sections are now preceded by a newline.
-
- BUG FIXES:
+ - 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.
+
+ - Lowered memory use 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 an empty one
+ (e.g. empty: :file1 or ::module/file2). This means that local use of
+ brace expansion now works: rsync -av host:dir/{f1,f2} .
+
+ - 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 (*?[).
+
+ - 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,
+ acl-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, and it even
+ supports OS X xattrs (which includes their resource fork data). If you
+ need to have backward compatibility with old, xattr-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.
+ It even supports the storing of foreign ACL data on your backup server.
+ 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 the default list of
+ file suffixes that will not be compressed when using --compress.
+
+ - 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.
- * 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)
+ - 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.)
- - 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.]
+ - 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).
- - "**/foo" now matches at the base of the transfer (like /foo
- does). [Use "/**/foo" to get the old behavior in all versions.]
+ - 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).
- - 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.]
+ - 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.
- - 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.]
+ - 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).
- * 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)
+ - Protocol 30 now uses MD5 checksums instead of MD4.
- * 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)
+ - Changed the --append option to not checksum the existing data in the
+ destination file, which speeds up file appending.
- * 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 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 a crash bug when interacting with older rsync versions and
- multiple files of the same name are destined for the same dir.
- (Wayne Davison)
+ - Documented and extended the support for the RSYNC_CONNECT_PROG variable
+ that can be used to enhance the client side of a daemon connection.
- * Keep tmp names from overflowing MAXPATHLEN.
+ - Improved the dashes and double-quotes in the nroff manpage output.
- * Make --link-dest honor the absence of -p, -o, and -g.
+ - We now support a lot more --no-OPTION override options.
- * Made rsync treat a trailing slash in the destination in a more
- consistent manner.
+ INTERNAL:
- * Fixed file I/O error detection. (John Van Essen)
+ - 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.
- * 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.
+ - Rsync now supports the transfer of 64-bit timestamps (time_t values).
- * Print heap statistics when verbose >= 2 instead of when >= 1.
+ - Fixed a build problem with older (2.x) versions of gcc.
- * Fixed a compression (-z) bug when syncing a mostly-matching file
- that contains already-compressed data. (Yasuoka Masahiko and
- Wayne Davison)
+ - Added some isType() functions that make dealing with signed characters
+ easier without forcing variables via casts.
- * Fixed a bug in the --backup code that could cause deleted files
- to not get backed up.
+ - Changed strcat/strcpy/sprintf function calls to use safer versions.
- * 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).
+ - Upgraded the included popt version to 1.10.2 and improved its use of
+ string-handling functions.
- * Call setgroups() in a more portable manner.
+ - Added missing prototypes for compatibility functions from the lib dir.
- * Improved file-related error messages to better indicate exactly
- what pathname failed. (Wayne Davison)
+ - Configure determines if iconv() has a const arg, allowing us to avoid a
+ compiler warning.
- * Fixed some bugs in the handling of --delete and --exclude when
- using the --relative (-R) option. (Wayne Davison)
+ - Made the sending of some numbers more efficient for protocol 30.
- * 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)
+ - Make sure that a daemon process doesn't mind if the client was weird and
+ omitted the --server option.
- * 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)
+ - Improved the use of "const" on pointers.
- * Added a fix that should give ssh time to restore the tty settings
- if the user presses Ctrl-C at an ssh password prompt.
+ - Improved J.W.'s pool_alloc routines to add a way of freeing older
+ sections of a pool's memory.
- INTERNAL:
+ - The getaddrinfo.c compatibility code in the "lib" dir was replaced with
+ some new code (derived from samba, derived from PostgreSQL) that has a
+ better license than the old code.
- * Eliminated vestigial support for old versions that we stopped
- supporting. (J.W. Schultz)
+ DEVELOPER RELATED:
- * Simplified some of the option-parsing code. (Wayne Davison)
+ - Rsync is now licensed under the GPLv3 or later.
- * Some cleanup made to the exclude code, as well as some new
- defines added to enhance readability. (Wayne Davison)
+ - 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,
+ but another file system does).
- * 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)
+ - Rsync now has a way of handling protocol-version changes during the
+ development of a new protocol version. This causes any out-of-sync
+ versions to speak an older protocol rather than fail in a cryptic manner.
+ This addition makes it safe to deploy a pre-release version that may
+ interact with the public. This new exchange of sub-version info does not
+ interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which
+ does not have enough range to allow the main protocol number to be
+ incremented for every minor tweak in that happens during development).
