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.
