- - Lower memory use, more optimal transfer of data over the socket,
- and lower CPU usage (see the INTERNAL section for details).
-
- - The RSYNC_PROXY environment variable can now contain a
- "USER:PASS@" prefix before the "HOST:PORT" information.
- (Bardur Arantsson)
-
- - 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've processed. It also
- shows better current-rate-of-transfer and remaining-transfer-time
- values.
-
- - Documentation changes now attempt to describe some often mis-
- understood features more clearly.
-
- BUG FIXES:
-
- - When -x (--one-file-system) is combined with -L (--copy-links) or
- --copy-unsafe-links, no symlinked files are skipped, even if the
- referent file is on a different filesystem.
-
- - The --link-dest code now works properly for a non-root user when
- (1) the UIDs of the source and destination differ and -o was
- specified, or (2) when the group of the source can't be used on
- the destination and -g was specified.
-
- - 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).
-
- - 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.
-
- - Fixed a byte-order problem in --batch-mode on big-endian machines.

-
- - When using --cvs-exclude, the exclude items we get from a
- per-directory's .cvsignore file once again only affect that one
- directory (not all following directories too). The items are also
- now properly word-split and parsed without any +/- prefix parsing.
-
- - 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).
-
- - Fixed some bugs in the handling of group IDs for non-root users:
- (1) It properly handles a group that the sender didn't have a name
- for (it would previously skip changing the group on any files in
- that group). (2) If --numeric-ids is used, rsync no longer
- attempts to set groups that the user doesn't have the permission
- to set.
-
- - Fixed the "refuse options" setting in the rsyncd.conf file.
-
- - Improved the -x (--one-file-system) flag's handling of any mount-
- point directories we encounter. It is both more optimal (in that
- it no longer does a useless scan of the contents of the mount-
- point dirs) and also fixes a bug where a remapped mount of the
- original filesystem could get discovered in a subdir we should be
- ignoring.
-
- - Rsync no longer discards a double-slash at the start of a filename
- when trying to open the file. It also no longer constructs names
- that start with a double slash (unless the user supplied them).
-
- - Path-specifying options to a daemon should now work the same with
- or without chroot turned on. Previously, such a option (such as
- --link-dest) would get its absolute path munged into a relative
- one if chroot was not on, making that setting fairly useless.
- Rsync now transforms the path into one that is based on the
- module's base dir when chroot is not enabled.
-
- - Fixed a compatibility problem interacting with older rsync
- versions that might send us an empty --suffix value without
- telling us that --backup-dir was specified.
-
- - The "hosts allow" option for a daemon-over-remote-shell process
- now has improved support for IPv6 addresses and a fix for systems
- that have a length field in their socket structs.
-
- - Fixed the ability to request an empty backup --suffix when sending
- files to an rsync daemon.
+ - 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.
+
+ - 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 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.
