+NEWS for rsync 2.6.2 (30 Apr 2004)
+Protocol: 28 (unchanged)
+Changes since 2.6.1:
+
+ 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.
+
+ - Rsync now checks the return value of the close() function to
+ better report disk-full problems on an NFS file system.
+
+ - 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.)
+
+ - An obscure uninitialized-variable bug was fixed in the uid/gid
+ code. (This bug probably had no ill effects.)
+
+ BUILD CHANGES:
+
+ - 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 compile problem on systems that don't define
+ AI_NUMERICHOST.
+
+ - 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".
+
+ 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.
+
+ 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 cleanup of the variable types make 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).
+
+ - 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).
+
+ 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.

+NEWS for rsync 2.6.0 (1 Jan 2004)
+Protocol: 27 (changed)
+Changes since 2.5.7:
+
+ ENHANCEMENTS:
+
+ * "ssh" is now the default remote shell for rsync. If you want to
+ change this, configure like this: "./configure --with-rsh=rsh".
+
+ * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
+ Note that --from0 affects the line-ending character for all the
+ files read by the --*-from options. (Wayne Davison)
+
+ * Length of csum2 is now per-file starting with protocol version
+ 27. (J.W. Schultz)
+
+ * Per-file dynamic block size is now sqrt(file length). The
+ per-file checksum size is determined according to an algorithm
+ 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 --stats option no longer includes the (debug) malloc summary
+ unless the verbose option was specified at least twice.
+
+ * Added a new error/warning code for when files vanish from the
+ sending side. Made vanished source files not interfere with the
+ file-deletion pass when --delete-after was specified.
+
+ * Various trailing-info sections are now preceded by a newline.
+
+ BUG FIXES:
+
+ * Fixed several exclude/include matching bugs when using wild-cards.
+ This has a several user-visible effects, all of which make the
+ matching more consistent and intuitive. This should hopefully not
+ cause anyone problems since it makes the matching work more like
+ what people are expecting. (Wayne Davison)
+
+ - A pattern with a "**" no longer causes a "*" to match slashes.
+ For example, with "/*/foo/**", "foo" must be 2 levels deep.
+ [If your string has BOTH "*" and "**" wildcards, changing the
+ "*" wildcards to "**" will provide the old behavior in all
+ versions.]
+
+ - "**/foo" now matches at the base of the transfer (like /foo
+ does). [Use "/**/foo" to get the old behavior in all versions.]
+
+ - A non-anchored wildcard term floats to match beyond the base of
+ the transfer. E.g. "CVS/R*" matches at the end of the path,
+ just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
+ to get the old behavior in all versions.]
+
+ - Including a "**" in the match term causes it to be matched
+ against the entire path, not just the name portion, even if
+ there aren't any interior slashes in the term. E.g. "foo**bar"
+ would exclude "/path/foo-bar" (just like before) as well as
+ "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
+ old behavior in all versions.]
+
+ * The exclude list specified in the daemon's config file is now
+ properly applied to the pulled items no matter how deep the
+ user's file-args are in the source tree. (Wayne Davison)
+
+ * 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)
+
+ * Fixed a crash bug when interacting with older rsync versions and
+ multiple files of the same name are destined for the same dir.
+ (Wayne Davison)
+
+ * Keep tmp names from overflowing MAXPATHLEN.
+
+ * Make --link-dest honor the absence of -p, -o, and -g.
+
+ * Made rsync treat a trailing slash in the destination in a more
+ consistent manner.
+
+ * Fixed file I/O error detection. (John Van Essen)
+
+ * Fixed bogus "malformed address {hostname}" message in rsyncd log
+ when checking IP address against hostnames from "hosts allow"
+ and "hosts deny" parameters in config file.
+
+ * Print heap statistics when verbose >= 2 instead of when >= 1.
+
+ * Fixed a compression (-z) bug when syncing a mostly-matching file
+ that contains already-compressed data. (Yasuoka Masahiko and
+ Wayne Davison)
+
+ * Fixed a bug in the --backup code that could cause deleted files
+ to not get backed up.
+
+ * When the backup code makes new directories, create them with mode
+ 0700 instead of 0755 (since the directory permissions in the
+ backup tree are not yet copied from the main tree).
+
+ * Call setgroups() in a more portable manner.
+
+ * Improved file-related error messages to better indicate exactly
+ what pathname failed. (Wayne Davison)
+
+ * Fixed some bugs in the handling of --delete and --exclude when
+ using the --relative (-R) option. (Wayne Davison)
+
+ * Fixed bug that prevented regular files from replacing
+ special files and caused a directory in --link-dest or
+ --compare-dest to block the creation of a file with the
+ same path. A directory still cannot be replaced by a
+ regular file unless --delete specified. (J.W. Schultz)
+
+ * Detect and report when open or opendir succeed but read and
+ readdir fail caused by network filesystem issues and truncated
+ files. (David Norwood, Michael Brown, J.W. Schultz)
+
+ * Added a fix that should give ssh time to restore the tty settings
+ if the user presses Ctrl-C at an ssh password prompt.
+
+ INTERNAL:
+
+ * Eliminated vestigial support for old versions that we stopped
+ supporting. (J.W. Schultz)
+
+ * Simplified some of the option-parsing code. (Wayne Davison)
+
+ * Some cleanup made to the exclude code, as well as some new
+ defines added to enhance readability. (Wayne Davison)
+
+ * Changed the protocol-version code so that it can interact at a
+ lower protocol level than the maximum supported by both sides.
+ Added an undocumented option, --protocol=N, to force the value
+ we advertise to the other side (primarily for testing purposes).
+ (Wayne Davison)
