- - 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).
+ - 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 have an
+ empty hostname, as seen here: :file1 ::module/file2. This means that
+ local use of brace expansion now works: rsync -av host:path/{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, 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. (If you need
+ to have backward compatibility with old, 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.
+ 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.
