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) + + NEWS for rsync 2.5.7 (4 Dec 2003) Protocol: 26 (unchanged) Changes since 2.5.6: @@ -411,6 +790,8 @@ Changes since 2.4.6: Partial Protocol History RELEASE DATE VER.
