This allows the log - file to get cleaned out by another process. + * 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. - * Change to using libpopt rather than getopt for processing - options. This makes the code cleaner and the behaviour more - consistent across platforms. popt is included and built if not - installed on the platform. + * Fixed a byte-order problem in --batch-mode on big-endian + machines. (Jay Fenlason) - * More details in --version, including note about whether 64-bit - files, symlinks and hardlinks are supported. + * Fixed configure bug when running "./configure --disable-ipv6". - * MD4 code may use less CPU cycles. + * Fixed "make test" bug when build dir is not the source dir. - * Use mkstemp on systems where it is secure. If we use mktemp, - explain that we do it in a secure way. + * 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). - * --whole-file is the default when source and target are on the - local machine. + * 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. - BUG FIXES: + * 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). - * Attempt to fix Large File Summit support on AIX. + * Less memory is used when --checksum is specified. - * Attempt to fix error handling lockup bug. + * Less memory is used in the file list (a per-file savings). - * Give a non-0 exit code if *any* of the files we have been asked - to transfer fail to transfer + * 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) - * Fix --cvs-exclude sigsegv bug. + * 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). - * Applied "simple nohang patch" from 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. - * Update to work with autoconf2.50 and 2.13. + * Improved the internal uid/gid code to be more portable and + a little more optimized.
