(Wayne Davison) + + * 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). + (Wayne Davison) + + * 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. (Wayne Davison) + + * Fixed a byte-order problem in --batch-mode on big-endian + machines. (Jay Fenlason) + + * Fixed configure bug when running "./configure --disable-ipv6". + (Wayne Davison) + + * 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. + + 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. (Wayne Davison) + + * Some variable-type cleanup that makes the code more consistent. + (Wayne Davison) + + * 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. + + * Got rid of support for protocol versions 17 and 18 (which are + both over 6 years old). (Wayne Davison) + + * 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). (Wayne Davison) + + * 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. + + * Optimized the -x (--one-file-system) flag's handling of any + mount-point directories we encounter (it no longer scans the + contents of the mount-point dirs, just to throw away the data). + + * Improved the internal uid/gid code to be more portable and + a little more optimized. + + +NEWS for rsync 2.6.0 (1 Jan 2004) Protocol: 27 (changed) -Changes since version 2.5.7: +Changes since 2.5.7: ENHANCEMENTS: + * "ssh" is now the default remote shell for rsync.
