ENHANCEMENTS:
+ * Lower memory use and more optimal transfer of data over
+ the socket (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're processed.
+
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 referant file is on a different filesystem.
+
* The --link-dest code now works properly for a non-root user
- when the UIDs of the source and destination differ and -u was
+ when the UIDs of the source and destination differ and -o was
specified, and when the group of the source can't be used on
the destination and -g was specified. (Wayne Davison)
- * Fixed the caching of the full PATH/NAME strings to avoid the
- current name getting lost if too many other names were
- expanded during the processing (such as when -H 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.
+ * 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. (Wayne Davison)
+
+ * Fixed a byte-order problem in --batch-mode on big-endian
+ machines. (Jay Fenlason)
+
+ * Fixed configure bug when running "./configure --disable-ipv6".
+ (Wayne Davison)
+
+ * Fixed "make test" bug when build dir is not the source dir.
+
+ * 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).
+
+ * 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.
+
+ * 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.
INTERNAL:
- * Most of the I/O is now buffered, which has a particularly
- large effect under MS Windows. (Craig Xxx and Wayne Davison)
+ * Most of the I/O is now buffered, which results in a pretty
+ large speedup when running under MS Windows. (Craig Barratt)
* Optimizations to the name-handling/comparing code have made
- some significant reductions in user CPU time for large file
+ some significant reductions in user-CPU time for large file
sets. (Wayne Davison)
+ * Some variable-type cleanup that makes the code more consistent.
+ (Wayne Davison)
+
+ * Reduced memory requirements of hard link preservation.
+ (J.W. Schultz)
+
+ * Implemented a new algorithm for hard-link handling that speeds
+ up the code significantly. (J.W. Schultz and Wayne Davison)
+
+ * The --hard-link option now uses the first existing file in the
+ group of linked files as the basis for the transfer. This
+ prevents the sub-optimal transfer of a file's data when a new
+ hardlink is added on the sending side and it sorts alphabetically
+ earlier in the list than the files that are already present on the
+ receiving side.
+
+ * Got rid of support for protocol versions 17 and 18 (which are
+ both over 6 years old). (Wayne Davison)
+
+ * More optimal data transmission for --hard-links (protocol 28).
+
+ * More optimal data transmission for --checksum (protocol 28).
+
+ * Less memory is used when --checksum is specified.
+
+ * Less memory is used in the file list (a per-file savings).
+
+ * Changed hardlink info and file_struct + strings to use
+ allocation pools. This reduces memory use for large
+ filesets and permits freeing memory to the OS. (J.W. Schultz)
+
+ * 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.
+
+ * Optimized the -x (--one-file-system) flag's handling of any
+ mount-point directories we encounter (it no longer scans the
+ contents of the mount-point dirs, just to throw away the data).
+
+ * Improved the internal uid/gid code to be more portable and
+ a little more optimized.
