- * "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:
-
- * 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.
- [If your string has BOTH "*" and "**" wildcards, changing the
- "*" wildcards to "**" will provide the old behavior in all
- versions.]
-
- - "**/foo" now matches at the base of the transfer (like /foo
- does). [Use "/**/foo" to get the old behavior in all versions.]
-
- - 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.]
-
- - 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.]
-
- * 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)
-
- * 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.
-
- * Print heap statistics when verbose >= 2 instead of when >= 1.
-
- * Fixed a compression (-z) bug when syncing a mostly-matching file
- that contains already-compressed data. (Yasuoka Masahiko and
- Wayne Davison)
-
- * Fixed a bug in the --backup code that could cause deleted files
- to not get backed up.
-
- * 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).
-
- * 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)
-
- * 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)
-
- * Added a fix that should give ssh time to restore the tty settings
- if the user presses Ctrl-C at an ssh password prompt.
+ - Rsync now supports popt's option aliases, which means that you can
+ use /etc/popt and/or ~/.popt to create your own option aliases.
+
+ - Added the --delete-during (--del) option which will delete files
+ from the receiving side incrementally as each directory in the
+ transfer is being processed. This makes it more efficient than the
+ default, before-the-transfer behavior, which is now also available as
+ --delete-before (and is still the default --delete-WHEN option that
+ will be chosen if --delete or --delete-excluded is specified without
+ a --delete-WHEN choice). All the --del* options infer --delete, so
+ an rsync daemon that refuses "delete" will still refuse to allow any
+ file-deleting options (including the new --remove-sent-files option).
+
+ - All the --delete-WHEN options are now more memory efficient:
+ Previously an duplicate set of file-list objects was created on the
+ receiving side for the entire destination hierarchy. The new
+ algorithm only creates one directory of objects at a time (for files
+ inside the transfer).
+
+ - Added the --copy-dest option, which works like --link-dest except
+ that it locally copies identical files instead of hard-linking them.
+
+ - Added support for specifying multiple --compare-dest, --copy-dest, or
+ --link-dest options, but only of a single type. (Promoted from the
+ patches dir and enhanced.) (Requires protocol 29.)
+
+ - Added the --max-size option. (Promoted from the patches dir.)
+
+ - The daemon-mode options are now separated from the normal rsync
+ options so that they can't be mixed together. This makes it
+ impossible to start a daemon that has improper default option values
+ (which could cause problems when a client connects, such as hanging
+ or crashing).
+
+ - The --bwlimit option may now be used in combination with --daemon
+ to specify both a default value for the daemon side and a value
+ that cannot be exceeded by a user-specified --bwlimit option.
+
+ - Added the "port" parameter to the rsyncd.conf file. (Promoted from
+ the patches dir.) Also added "address". The command-line options
+ take precedence over a config-file option, as expected.
+
+ - In _exit_cleanup(): when we are exiting with a partially-received
+ file, we now flush any data in the write-cache before closing the
+ partial file.
+
+ - The --inplace support was enhanced to work with --compare-dest,
+ --link-dest, and (the new) --copy-dest options. (Requires protocol
+ 29.)
+
+ - Added the --dirs (-d) option for an easier way to copy directories
+ without recursion.
+
+ - Added the --list-only option, which is mainly a way for the client to
+ put the server into listing mode without needing to resort to any
+ internal option kluges (e.g. the age-old use of "-r --exclude="/*/*"
+ for a non-recursive listing). This option is used automatically
+ (behind the scenes) when a modern rsync speaks to a modern daemon,
+ but may also be specified manually if you want to force the use of
+ the --list-only option over a remote-shell connection.
+
+ - Added the --omit-dir-times (-O) option, which will avoid updating
+ the modified time for directories when --times was specified. This
+ option will avoid an extra pass through the file-list at the end of
+ the transfer (to tweak all the directory times), which may provide
+ an appreciable speedup for a really large transfer. (Promoted from
+ the patches dir.)
+
+ - Added the --filter (-f) option and its helper option, -F. Filter
+ rules are an extension to the existing include/exclude handling
+ that also supports nested filter files as well as per-directory
+ filter files (like .cvsignore, but with full filter-rule parsing).
+ This new option was chosen in order to ensure that all existing
+ include/exclude processing remained 100% compatible with older
+ versions. Protocol 29 is needed for full filter-rule support, but
+ backward-compatible rules work with earlier protocol versions.
+ (Promoted from the patches dir and enhanced.)
+
+ - Added the --delay-updates option that puts all updated files into
+ a temporary directory (by default ".~tmp~", but settable via the
+ --partial-dir=DIR option) until the end of the transfer. This
+ makes the updates a little more atomic for a large transfer.
+
+ - If rsync is put into the background, any output from --progress is
+ reduced.
+
+ - Documented the "max verbosity" setting for rsyncd.conf. (This
+ setting was added a couple releases ago, but left undocumented.)
+
+ - The sender and the generator now double-check the file-list index
+ they are given, and refuse to try to do a file transfer on a
+ non-file index (since that would indicate that something had gone
+ very wrong).
+
+ - Added the --itemize-changes (-i) option, which is a way to output a
+ more detailed list of what files changed and in what way. The effect
+ is the same as specifying a --log-format of "%i %n%L" (see both the
+ rsync and rsyncd.conf manpages). Works with --dry-run too.
+
+ - Added the --fuzzy (-y) option, which attempts to find a basis file
+ for a file that is being created from scratch. The current algorithm
+ only looks in the destination directory for the created file, but it
+ does attempt to find a match based on size/mod-time (in case the file
+ was renamed with no other changes) as well as based on a fuzzy
+ name-matching algorithm. This option requires protocol 29 because it
+ needs the new file-sorting order. (Promoted from patches dir and
+ enhanced.) (Requires protocol 29.)
+
+ - Added the --remove-sent-files option, which lets you move files
+ between systems.
+
+ - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal
+ enclosed in '[' and ']' (e.g. "[::1]"). (We already allowed IPv6
+ literals in the rsync://HOST:PORT/PATH format.)
+
+ - When rsync recurses to build the file list, it no longer keeps open
+ one or more directory handles from the dir's parent dirs.
+
+ - When building under windows, the default for --daemon is now to
+ avoid detaching, requiring the new --detach option to force rsync
+ to detach.
+
+ - The --dry-run option can now be combined with either --write-batch or
+ --read-batch, allowing you to run a do-nothing test command to see
+ what would happen without --dry-run.
+
+ - The daemon's "read only" config item now sets an internal read_only
+ variable that makes extra sure that no write/delete calls on the
+ read-only side can succeed.
+
+ - The log-format % escapes can now have a numeric field width in
+ between the % and the escape letter (e.g. "%-40n %08p").
+
+ - Improved the option descriptions in the --help text.
+
+ SUPPORT FILES:
+
+ - Added atomic-rsync to the support dir: a perl script that will
+ transfer some files using rsync, and then move the updated files into
+ place all at once at the end of the transfer. Only works when
+ pulling, and uses --link-dest and a parallel hierarchy of files to
+ effect its update.
+
+ - Added mnt-excl to the support dir: a perl script that takes the
+ /proc/mounts file and translates it into a set of excludes that will
+ exclude all mount points (even mapped mounts to the same disk). The
+ excludes are made relative to the specified source dir and properly
+ anchored.
+
+ - Added savetransfer.c to the support dir: a C program that can make
+ a copy of all the data that flows over the wire. This lets you test
+ for data corruption (by saving the data on both the sending side and
+ the receiving side) and provides one way to debug a protocol error.
+
+ - Added rrsync to the support dir: this is an updated version of Joe
+ Smith's restricted rsync perl script. This helps to ensure that only
+ certain rsync commands can be run by an ssh invocation.
