-NEWS for rsync 2.6.2 (30 Apr 2004)
-Protocol: 28 (unchanged)
-Changes since 2.6.1:
+NEWS for rsync 3.0.0 (UNRELEASED)
+Protocol: 30 (changed)
+Changes since 2.6.9:
BUG FIXES:
- - Fixed a major bug in the sorting of the filenames when --relative
- is used for some sources (just sources such as "/" and "/*" were
- affected). This fix ensures that we ask for the right file-list
- item when requesting changes from the sender.
+ - Fixed the output of -ii when combined with one of the --*-dest options:
+ it now itemizes all the items, not just the changed ones.
- - Rsync now checks the return value of the close() function to
- better report disk-full problems on an NFS file system.
+ - Made the output of all file types consistent when using a --*-dest
+ option. Prior versions used to output too many creation events for
+ matching items.
- - Restored the old daemon-server behavior of logging error messages
- rather than returning them to the user. (A better long-term fix
- will be sought in the future.)
+ - The code that waits for a child pid now handles being interrupted by a
+ signal. This fixes a problem with the pre-xfer exec function not being
+ able to get the exit status from the script.
- - An obscure uninitialized-variable bug was fixed in the uid/gid
- code. (This bug probably had no ill effects.)
+ - A negated filter rule now sends the negation option when sending the
+ filter rules.
- BUILD CHANGES:
+ - Fixed a problem with the --out-format (aka --log-format) option: it
+ would output superfluous directory information for a non-daemon rsync.
- - Got rid of the configure check for sys/sysctl.h (it wasn't used
- and was causing a problem on some systems). Also improved the
- broken-largefile-locking test to try to avoid failure due to an
- NFS build-dir.
+ - Fixed a problem with -vv (double --verbose) and --stats when "pushing"
+ files (which includes local copies). Version 2.6.9 would complete the
+ copy, but exit with an error when the receiver output its memory stats.
- - Fixed a compile problem on systems that don't define
- AI_NUMERICHOST.
+ - If --password-file is used on a non-daemon transfer, rsync now complains
+ and exits. This should help users figure out that they can't use this
+ option to control a remote shell's password prompt.
- - Fixed a compile problem in the popt source for compilers that
- don't support __attribute__.
-
- DEVELOPER RELATED:
-
- - Improved the testsuite's "merge" test to work on OSF1.
-
- - Two new diffs were added to the patches dir.

-NEWS for rsync 2.6.1 (26 Apr 2004)
-Protocol: 28 (changed)
-Changes since 2.6.0:
-
- SECURITY FIXES:
-
- - Paths sent to an rsync daemon are more thoroughly sanitized when
- chroot is not used. If you're running a non-read-only rsync
- daemon with chroot disabled, *please upgrade*, ESPECIALLY if the
- user privs you run rsync under is anything above "nobody".
+ - Make sure that directory permissions of a newly-created destination
+ directory are handled right when --perms is left off.
ENHANCEMENTS:
- - 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.
- (Jay Fenlason)
-
- - 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.
+ - A new incremental-recursion algorithm is now used when rsync is talking
+ to another 3.0.0 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.
+
+ - 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.
+
+ - 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. (If you need
+ to have backward compatibility with old, patched versions, the new
+ acls.diff patch that will add that.)
+
+ - 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, the new
+ xattrs.diff patch that will add that.)
+
+ - 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 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 man page for an explanation of the --iconv
+ option's settings.
+
+ - You may specify --max-delete=0 to a 3.0.0 client as long as the receiving
+ side is at least version 3.0.0. This means that you can pull from an
+ older rsync with this option, but pushing to an older rsync will generate
+ an error. *Be sure to never specify a 0 value to an older rsync client,
+ or it will be silently ignored.*
+
+ - The --hard-link option now uses less memory on both the sending and
+ receiving side for all protocol versions. For protocol 30, the use of a
+ hashtable on the sending side allows us to more efficiently convey to the
+ receiver what files are linked together. This reduces the amount of data
+ sent over the socket by a considerable margin (rather than adding more
+ data), and limits the in-memory storage of the device+inode information
+ to just the sending side for the new protocol 30, or to the receiving
+ side when speaking an older protocol (note that older rsync versions kept
+ the device+inode information on both sides).
+
+ - A lot more --no-OPTION override options are now supported.
INTERNAL:
- - Most of the I/O is now buffered, which results in a pretty large
- speedup when running under MS Windows. (Craig Barratt)
+ - The file-list sorting algorithm now uses a sort that keeps any same-
+ named items in the same order as they were specified. This allows
+ rsync to always ensure that the first of the duplicates is the one
+ that will be included in the copy. The new sort was also faster
+ than the glibc version of qsort() and mergesort() in my testing.
- - Optimizations to the name-handling/comparing code have made some
- significant reductions in user-CPU time for large file sets.
+ - Rsync now supports the transfer of 64-bit timestamps (time_t values).
- - Some cleanup of the variable types make the code more consistent.
+ - Fixed a build problem with older (2.x) versions of gcc.
- - Reduced memory requirements of hard link preservation.
- (J.W. Schultz)
+ - Added some isType() functions that make dealing with signed characters
+ easier without forcing variables via casts.
- - Implemented a new algorithm for hard-link handling that speeds up
- the code significantly. (J.W. Schultz and Wayne Davison)
+ - Upgraded the included popt version to 1.10.2 and improved its use of
+ string-handling functions.
- - 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.
+ - Added missing prototypes for compatibility functions from the lib dir.
- - 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)
+ - Configure determines if iconv() has a const arg, allowing us to avoid a
+ compiler warning.
- - More optimal data transmission for --hard-links (protocol 28).
+ - Made the sending of some numbers more efficient for protocol 30.
- - More optimal data transmission for --checksum (protocol 28).
+ - Make sure that a daemon process doesn't mind if the client was weird and
+ omitted the --server option.
- - Less memory is used when --checksum is specified.
+ - Improved the use of "const" on pointers.
- - Less memory is used in the file list (a per-file savings).
-
- - 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.
-
- - 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)
-
- - 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 (which mainly affected hard-link messages and
- verbose --stats output).
-
- - Improved the internal uid/gid code to be more portable and a
- little more optimized.
-
- - The device numbers sent when using --devices are now sent as
- separate major/minor values with 32-bit accuracy (protocol 28).
- Previously, the 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 (with both ends of the
- connection are using protocol 28). Note that optimizations in the
- binary protocol for sending the device numbers often results in
- fewer bytes being used than before, even though more precision is
- now available.
-
- - Some cleanup of the exclude/include structures and its code made
- things clearer (internally), simpler, and more efficient.
-
- - 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. (Note that the
- batch code is still considered to be experimental.)
-
- BUILD CHANGES:
-
- - The configure script now accepts --with-rsyncd-conf=PATH to
- override the default value of the /etc/rsyncd.conf file.
-
- - Fixed configure bug when running "./configure --disable-ipv6".
-
- - Fixed compilation problem on Tru64 Unix (having to do with
- sockaddr.sa_len and sockaddr.sin_len).
+ - Improved J.W.'s pool_alloc routines to add a way of freeing older
+ sections of a pool's memory.
DEVELOPER RELATED:
- - Fixed "make test" bug when build dir is not the source dir.
-
- - Added a couple extra diffs in the "patches" dir, removed the ones
- that got applied, and rebuilt the rest.
-
+ - Rsync now has a way of handling protocol-version changes during the
+ development of a new protocol version. This exchange of sub-version
+ info does not interfere with the {MIN,MAX}_PROTOCOL_VERSION checking
+ in older versions (which would be the case if every minor change made
+ to the protocol in CVS incremented the main PROTOCOL_VERSION value).
