NEWS for rsync 2.6.1 (UNRELEASED) Protocol: 28 (changed) Changes since 2.6.0: ENHANCEMENTS: * Lower memory use and more optimal transfer of data over the socket (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. * The configure script now accepts --with-rsyncd-conf=PATH to override the default value of the /etc/rsyncd.conf file. * Added a couple extra diffs in the "patches" dir, removed the ones that got applied, and rebuilt the rest. 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 referant 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) * Fixed configure bug when running "./configure --disable-ipv6". * Fixed "make test" bug when build dir is not the source dir. * 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). * When transferring a file that has group 0 with -g specified (typically via -a) and not enough privs to retain the group, rsync no longer complains about "chown" failing. * 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 remaped mount of the original filesystem could get discovered on a disk 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). * Fixed compilation problem on Tru64 Unix (having to do with sockaddr.sa_len and sockaddr.sin_len). 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 variable-type cleanup that makes 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). * Changed hardlink info and file_struct + strings to use allocation pools. This reduces memory use for large filesets 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 (the latter mainly affected hard-link messages and verbose --stats output). * 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. * Improved the internal uid/gid code to be more portable and a little more optimized.
