-NEWS for rsync 2.6.1 (UNRELEASED)
-Protocol: 28 (changed)
-Changes since 2.6.0:
-
- 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've processed.
- It also shows better current-rate-of-transfer and remaining-
- transfer-time values.
-
- * The configure script now accepts --with-rsyncd-conf=PATH
- to override the default value of the /etc/rsyncd.conf file.
-
- * Added a couple extra diffs in the "patches" dir, removed the
- ones that got applied, and rebuilt the rest.
+NEWS for rsync 3.1.0 (UNRELEASED)
+Protocol: 30 (unchanged)
+Changes since 3.0.4:
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. (Jay Fenlason)
-
- * Fixed configure bug when running "./configure --disable-ipv6".
-
- * 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). The
- items are also now properly word-split and parsed without
- any +/- prefix munging.
-
- * 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.
+ - Changed the way --progress overwrites its prior output in order to make
+ it nearly impossible for the progress to get overwritten by an error.
- * 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).
-
- * Fixed compilation problem on Tru64 Unix (having to do with
- sockaddr.sa_len and sockaddr.sin_len).
-
- * Fixed a compatibility problem interacting with older rsync
- versions that might send us an empty suffix without telling us
- about the backup-dir.
-
- * 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.
-
- INTERNAL:
-
- * 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
- sets.
-
- * Some variable-type cleanup that makes the code more consistent.
-
- * 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.
-
- * Dropped support for protocol versions less than 20
- (2.3.0 released 15 Mar 1999) and activated warnings for
- protocols less than 25 (2.5.0 released 23 Aug 2001)
- (Wayne Davison and J.W. Schultz, severally)
-
- * 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).
+ ENHANCEMENTS:
- * The generator is now better about not modifying the file list
- during the transfer in order to avoid a copy-on-write memory
- bifurcation (on systems where fork() uses shared memory).
- Previously, rsync's shared memory would slowly become unshared,
- resulting in real memory usage nearly doubling on the receiving
- side by the end of the transfer. Now, as long as permissions
- are being preserved, the shared memory should remain that way
- for the entire transfer.
+ - Added the --remote-option=OPT (-M OPT) command-line option that is useful
+ for things like sending a remote --log-file=FILE or --fake-super option.
- * Changed hardlink info and file_struct + strings to use
- allocation pools. This reduces memory use for large file-
- sets and permits freeing memory to the OS. (J.W. Schultz)
+ - Added the --info=FLAGS and --debug=FLAGS options to allow finer-grained
+ control over what is output. Added an extra type of --progress output
+ using --info=progress2.
- * 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 and verbose --stats output).
+ - Added the "%C" escape to the log-output handling, which will output the
+ MD5 checksum of any transferred file, or all files if --checksum was
+ specified (when protocol 30 or above is in effect).
- * 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.
+ DEVELOPER RELATED:
- * Improved the internal uid/gid code to be more portable and
- a little more optimized.
+ - Added more conditional debug output.
- * Device numbers are now sent as separate major/minor values
- with 32-bit accuracy for each one (protocol 28). Previously
- hard-link device data was sent as a single 64-bit number, and
- copied devices were sent as a single 32-bit number. This will
- make inter-operation of 64-bit binaries more compatible with
- their 32-bit brethren. Note that optimizations in the binary
- protocol often sends the device data using fewer bytes than
- before, even though more precision is now available.
+ - Really big numbers are now output using our own big-num routine rather
+ than casting them to a double and using a %.0f conversion.
- * Some cleanup of the exclude/include structures and its code
- made things clearer, simpler, and more efficient.
+ - The pool_alloc library has received some minor improvements in alignment
+ handling.
