- - Added the --partial-dir=DIR option that lets you specify where to
- (temporarily) put a partially transferred file (instead of over-
- writing the destination file). E.g. --partial-dir=.rsync-partial
-
- - Added --keep-dirlinks (-K), which allows you to symlink a directory
- onto another partition on the receiving side and have rsync treat it
- as matching a normal directory from the sender.
-
- - Added the --inplace option that tells rsync to write each destination
- file without using a temporary file. The matching of existing data
- in the destination file can be severely limited by this, but there
- are also cases where this is more efficient (such as appending data).
- Use only when needed (see the man page for more details).
-
- - Added the "write only" option for the daemon's config file.
-
- - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
- and documented all these options in the man page.
-
- - Improved the handling of the --bwlimit option so that it's less
- bursty, more accurate, and works properly over a larger range of
- values.
-
- - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and
- SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address.
-
- - Added the --checksum-seed=N option for advanced users.
-
- - Batch writing/reading has a brand-new implementation that is simpler,
- fixes a few weird problems with the old code (such as no longer
- sprinkling the batch files into different dirs or even onto different
- systems), and is much less intrusive into the code (making it easier
- to maintain for the future). The new code generates just one data
- file instead of three, which makes it possible to read the batch via
- stdin over a remote shell. Also, the old requirement of forcing the
- same fixed checksum-seed for all batch processing has been removed.
-
- - If an rsync daemon has a module set with "list = no" (which hides its
- presence in the list of available modules), a user that fails to
- authenticate gets the same "unknown module" error that they would get
- if the module were actually unknown (while still logging the real
- error to the daemon's log file). This prevents fishing for module
- names.
-
- - The daemon's "refuse options" config item now allows you to match
- option names using wildcards and/or the single-letter option names.
-
- - The finished file now gets its permissions and modified-time updated
- before it gets moved into place.
+ - 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 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.
+
+ - All the --delete-WHEN options are now more memory efficient:
+ Previously an entire 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 support for specifying multiple --compare-dest or --link-dest
+ options, but only of a single type. (Promoted from the patches dir
+ and enhanced.)
+
+ - Added the --max-size option. (Promoted from the patches dir.)
+
+ - The daemon-mode options were separated from the normal rsync options
+ so that they can't be mixed together. This makes it impossible to
+ start a daemon that had improper default option values that could
+ cause problems when a client connects (e.g. a hang or an abort).
+
+ - 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". A command-line option
+ will 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 and
+ --link-dest. (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 can result in
+ 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 in any way and how they
+ changed. The effect is the same as specifying a --log-format of
+ "%i %n%L" (see the rsyncd.conf manpage). Works with --dry-run too.
+
+ - Added the --fuzzy 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.)
+
+ - Added the --remove-sent-files option, which lets you move files
+ between systems.
+
+ - When building under windows, the default for --daemon is now to
+ avoid detaching, requiring the new --detach option to force rsync
+ to detach.
+
+ - 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) or provides a way to help debug a protocol error.
+
+ - Added rrsync to the support dir: this is my 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.
