+NEWS for rsync 2.6.1 (UNRELEASED)
+Protocol: 28 (changed)
+Changes since 2.6.0:
ENHANCEMENTS:
- - Added --files-from, --no-relative, --no-implied-dirs, and --from0.
- Note that --from0 affects the line-ending character for all the
- --*-from options. (Wayne Davison)
+ * Lower memory use and more optimal transfer of data over
+ the socket (see the INTERNAL section for details).
- - Length of csum2 is now per-file starting with protocol verison
- 27. (J.W. Schultz)
+ * The RSYNC_PROXY environment variable can now contain a
+ "USER:PASS@" prefix before the "HOST:PORT" information.
+ (Bardur Arantsson)
- - Per-file dynamic block size is now sqrt(file length).
+ * 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.
+ It was also improved to better show the current rate of
+ transfer (which is used to estimate the remaining transfer
+ time).
- The per-file checksum size is determined according
- to an algorythm provided by Donovan Baarda which
- reduces the probability of rsync algorithm
- corrupting data and falling back using the whole md4
- checksums. (J.W. Schultz, Donovan Baarda)
+ * The configure script now accepts --with-rsyncd-conf=PATH
+ to override the default value of the /etc/rsyncd.conf file.
BUG FIXES:
- - for protocol version >= 27, mdfour_tail() is called when the
- block size (including checksum_seed) is a multiple of 64.
- Previously it was not called, giving the wrong MD4 checksum.
- (Craig Barratt)
-
- - for protocol version >= 27, a 64 bit bit counter is used in
- mdfour.c as required by the RFC. Previously only a 32 bit bit
- counter was used, causing incorrect MD4 file checksums for
- file sizes >= 512MB - 4. (Craig Barratt)
+ * 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 -o was
+ specified, and when the group of the source can't be used on
+ the destination and -g was specified.
- - Fixed a crash bug when interacting with Craiolder rsync versioss and
- multiple files of the same name are destined for the same dir.
- (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).
+
+ * 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.
- - Keep tmp names from overflowing MAXPATHLEN.
+ * Fixed a byte-order problem in --batch-mode on big-endian
+ machines. (Jay Fenlason)
- INTERNAL:
-
- - Eliminated vestigial support for old versions that we stopped
- supporting. (J.W. Schultz)
-
- - Simplified some of the option-parsing code. (Wayne Davison)
+ * Fixed configure bug when running "./configure --disable-ipv6".
+ * Fixed "make test" bug when build dir is not the source dir.
-NEWS for rsync version 2.5.6, aka the dwd-between-jobs release
-Protocol: 26 (unchanged)
-Changes since version 2.5.5:
-
- ENHANCEMENTS:
+ * 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 --delete-after option now implies --delete. (Wayne Davison)
+ * 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.
- * The --suffix option can now be used with --backup-dir. (Michael
- Zimmerman)
+ * 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).
- * Combining "::" syntax with the -rsh/-e option now uses the
- specified remote-shell as a transport to talk to a (newly-spawned)
- server-daemon. This allows someone to use daemon features, such
- as modules, over a secure protocol, such as ssh. (JD Paul)
-
- * The rsync:// syntax for daemon connections is now accepted in the
- destination field.
-
- * If the file name given to --include-from or --exclude-from is "-",
- rsync will read from standard input. (J.W. Schultz)
-
- * New option --link-dest which is like --compare-dest except that
- unchanged files are hard-linked in to the destination directory.
- (J.W. Schultz)
+ * 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.
- * Don't report an error if an excluded file disappears during an
- rsync run. (Eugene Chupriyanov and Bo Kersey)
+ * Fixed the "refuse options" setting in the rsyncd.conf file.
- * Added .svn to --cvs-exclude list to support subversion. (Jon
- Middleton)
+ * 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 remaped
+ mount of the original filesystem could get discovered on a
+ disk we should be ignoring.
- * Properly support IPv6 addresses in the rsyncd.conf "hosts allow"
- and "hosts deny" fields. (Hideaki Yoshifuji)
+ * 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).
- * Changed exclude file handling to permit DOS or MAC style line
- terminations. (J.W. Schultz)
+ * Fixed compilation problem on Tru64 Unix (having to do with
+ sockaddr.sa_len and sockaddr.sin_len).
- * Ignore errors from chmod when -p/-a/--preserve-perms is not set.
- (Dave Dykstra)
-
- BUG FIXES:
-
- * Fix "forward name lookup failed" errors on AIX 4.3.3. (John
- L. Allen, Martin Pool)
-
- * Generate each file's rolling-checksum data as we send it, not
- in a separate (memory-eating) pass before hand. This prevents
- timeout errors on really large files. (Stefan Nehlsen)
-
- * Fix compilation on Tru64. (Albert Chin, Zoong Pham)
+ INTERNAL:
- * Better handling of some client-server errors. (Martin Pool)
+ * Most of the I/O is now buffered, which results in a pretty
+ large speedup when running under MS Windows. (Craig Barratt)
- * Fixed a crash that would occur when sending a list of files that
- contains a duplicate name (if it sorts to the end of the file
- list) and using --delete. (Wayne Davison)
+ * Optimizations to the name-handling/comparing code have made
+ some significant reductions in user-CPU time for large file
+ sets.
- * Fixed the file-name duplicate-removal code when dealing with multiple
- dups in a row. (Wayne Davison)
+ * Some variable-type cleanup that makes the code more consistent.
- * Fixed a bug that caused rsync to lose the exit status of its child
- processes and sometimes return an exit code of 0 instead of showing
- an error. (David R. Staples, Dave Dykstra)
+ * Reduced memory requirements of hard link preservation.
+ (J.W. Schultz)
- * Fixed bug in --copy-unsafe-links that caused it to be completely
- broken. (Dave Dykstra)
+ * Implemented a new algorithm for hard-link handling that speeds
+ up the code significantly. (J.W. Schultz and Wayne Davison)
- * Prevent infinite recursion in cleanup code under certain circumstances.
- (Sviatoslav Sviridov and Marc Espie)
+ * 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.
- * Fixed a bug that prevented rsync from creating intervening directories
- when --relative-paths/-R is set. (Craig Barratt)
+ * 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)
- * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara)
+ * More optimal data transmission for --hard-links (protocol 28).
- INTERNAL:
+ * More optimal data transmission for --checksum (protocol 28).
- * Many code cleanups and improved internal documentation. (Martin
- Pool, Nelson Beebe)
+ * Less memory is used when --checksum is specified.
- * Portability fixes. (Dave Dykstra and Wayne Davison)
+ * Less memory is used in the file list (a per-file savings).
- * More test cases. (Martin Pool)
+ * 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)
- * Some test-case fixes. (Brian Poole, Wayne Davison)
+ * 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).
- * Updated included popt to the latest vendor drop, version 1.6.4.
- (Jos Backus)
+ * 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.
- * Updated config.guess and config.sub to latest versions; this
- means rsync should build on more platforms. (Paul Green)
+ * Improved the internal uid/gid code to be more portable and
+ a little more optimized.
