(Wayne Davison) + - Fixed an age-old crash problem with --read-batch on a local copy + (rsync was improperly assuming --whole-file for the local copy). + + - Files specified in the daemon's "exclude" or "exclude from" config + items are now excluded from being uploaded (if the module is not + read-only) as well as downloaded. - * Fixed a byte-order problem in --batch-mode on big-endian - machines. (Jay Fenlason) + - When using --backup without a --backup-dir, rsync no longer preserves + the modify time on directories. This avoids confusing NFS. - * Fixed configure bug when running "./configure --disable-ipv6". - (Wayne Davison) + - Fixed a bug in the daemon authentication code when using one of the + batch-processing options. + + ENHANCEMENTS: - * Fixed "make test" bug when build dir is not the source dir. + - Added the "write only" option to the daemon's config file. - * 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). + - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) + and documented all these options in the man page. INTERNAL: - * Most of the I/O is now buffered, which results in a pretty - large speedup when running under MS Windows. (Craig Barratt) + - Some cleanup in the exclude code has saved some memory and made + things easier to maintain. - * Optimizations to the name-handling/comparing code have made - some significant reductions in user-CPU time for large file - sets. (Wayne Davison) + - Use rsyserr() in the various places that were still calling + rprintf() with strerror() as an arg. - * Some variable-type cleanup that makes the code more consistent. - (Wayne Davison) + BUILD CHANGES: - * Reduced memory requirements of hard link preservation. - (J.W. Schultz) + - Added a "gen" target to rebuild most of the various generated + files, including configure, config.h.in, the man pages, and + proto.h. - * Implemented a new algorithm for hard-link handling that speeds - up the code significantly. (J.W. Schultz and Wayne Davison) + - The timestamp of the proto.h file is unaltered by "make proto" + if the contents don't change. - * Got rid of support for protocol versions 17 and 18 (which are - both over 6 years old).

This fix ensures that we ask for the right file-list + item when requesting changes from the sender. - * 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 to through generator over - to the sender. (Wayne Davison) + - Rsync now checks the return value of the close() function to + better report disk-full problems on an NFS file system. - -NEWS for rsync 2.6.0 (1 Jan 2004) -Protocol: 27 (changed) -Changes since 2.5.7: + - 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.) - ENHANCEMENTS: + - 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. - * "ssh" is now the default remote shell for rsync. If you want to - change this, configure like this: "./configure --with-rsh=rsh". + - Fixed a compile problem on systems that don't define + AI_NUMERICHOST. - * 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) + - Fixed a compile problem in the popt source for compilers that + don't support __attribute__. - * Length of csum2 is now per-file starting with protocol version - 27. (J.W. Schultz) + DEVELOPER RELATED: - * 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) + - Improved the testsuite's "merge" test to work on OSF1. - * The --stats option no longer includes the (debug) malloc summary - unless the verbose option was specified at least twice. + - Two new diffs were added to the patches dir. - * 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. + +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) - * Various trailing-info sections are now preceded by a newline. + - 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: - * 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) + - 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. - - 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.] + - 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. - - "**/foo" now matches at the base of the transfer (like /foo - does). [Use "/**/foo" to get the old behavior in all versions.] + - 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 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.] + INTERNAL: - - 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.] + - Most of the I/O is now buffered, which results in a pretty large + speedup when running under MS Windows. (Craig Barratt) - * 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) + - Optimizations to the name-handling/comparing code have made some + significant reductions in user-CPU time for large file sets. - * 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) + - Some cleanup of the variable types make the code more consistent. - * 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) + - Reduced memory requirements of hard link preservation. + (J.W. Schultz) - * 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) + - Implemented a new algorithm for hard-link handling that speeds up + the code significantly. (J.W. Schultz and Wayne Davison) - * Keep tmp names from overflowing MAXPATHLEN. + - 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. - * Make --link-dest honor the absence of -p, -o, and -g. + - 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) - * Made rsync treat a trailing slash in the destination in a more - consistent manner. + - More optimal data transmission for --hard-links (protocol 28). - * Fixed file I/O error detection. (John Van Essen) + - More optimal data transmission for --checksum (protocol 28). - * 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. + - Less memory is used when --checksum is specified. - * Print heap statistics when verbose >= 2 instead of when >= 1. + - Less memory is used in the file list (a per-file savings). - * Fixed a compression (-z) bug when syncing a mostly-matching file - that contains already-compressed data. (Yasuoka Masahiko and - Wayne Davison) + - 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. - * Fixed a bug in the --backup code that could cause deleted files - to not get backed up. + - 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) - * 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). + - 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). - * Call setgroups() in a more portable manner. + - Improved the internal uid/gid code to be more portable and a + little more optimized. - * Improved file-related error messages to better indicate exactly - what pathname failed. (Wayne Davison) + - 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. - * Fixed some bugs in the handling of --delete and --exclude when - using the --relative (-R) option. (Wayne Davison) + - Some cleanup of the exclude/include structures and its code made + things clearer (internally), simpler, and more efficient. - * 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) + - 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.) - * 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) + BUILD CHANGES: - * Added a fix that should give ssh time to restore the tty settings - if the user presses Ctrl-C at an ssh password prompt. + - The configure script now accepts --with-rsyncd-conf=PATH to + override the default value of the /etc/rsyncd.conf file. - INTERNAL: + - 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). - * Eliminated vestigial support for old versions that we stopped - supporting. (J.W. Schultz) + DEVELOPER RELATED: - * Simplified some of the option-parsing code. (Wayne Davison) + - Fixed "make test" bug when build dir is not the source dir. - * Some cleanup made to the exclude code, as well as some new - defines added to enhance readability. (Wayne Davison) + - Added a couple extra diffs in the "patches" dir, removed the ones + that got applied, and rebuilt the rest. - * 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)
