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. + - If the user specifies a remote-host for both the source and destination, + we now output a syntax error rather than trying to open the destination + hostspec as a filename. - * Fixed a byte-order problem in --batch-mode on big-endian - machines. (Jay Fenlason) + - When --inplace creates a new destination file, rsync now creates it with + permissions 0600 instead of 0000 -- this makes restarting possible when + the transfer gets interrupted in the middle of sending a new file. - * Fixed configure bug when running "./configure --disable-ipv6". + - Reject the combination of --inplace and --sparse since the sparse-output + algorithm doesn't work when overwriting existing data. - * Fixed "make test" bug when build dir is not the source dir. + - Fixed the directory name in the error that is output when pop_dir() + fails. - * 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). + - Really fixed the parsing of a "!" entry in .cvsignore files this time. - * 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). + - If the generator gets a stat() error on a file, output it (this used to + require at least -vv for the error to be seen). - * 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. + - If waitpid() fails or the child rsync didn't exit cleanly, we now handle + the exit status properly and generate a better error. - * Fixed the "refuse options" setting in the rsyncd.conf file. + ENHANCEMENTS: - * 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. + - Added the --append option that makes rsync append data onto files + that are longer on the source than the destination (this includes new + files). - * 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). + - Added the --min-size=SIZE option to exclude small files from the + transfer. - * Fixed compilation problem on Tru64 Unix (having to do with - sockaddr.sa_len and sockaddr.sin_len). + - Added the --compress-level option to allow you to set how aggressive + rsync's compression should be (the option implies --compress). - * Fixed a compatibility problem interacting with older rsync - versions that might send us an empty suffix without telling us - about the backup-dir. + - Enhanced the parsing of the SIZE value for --min-size and --max-size. - * 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. + - If lutimes() and/or lchmod() are around, use them to allow the + preservation of attributes on symlinks. - * Fixed the ability to request an empty backup suffix when - sending files to an rsync daemon. + - Added two config items to the rsyncd.conf parsing: "pre-xfer exec" + and "post-xfer exec". These allow a command to be specified on a + per-module basis that will be run before and/or after a daemon-mode + transfer. - INTERNAL: + - When using the --relative option, you can now insert a dot dir in + the source path to indicate where the replication of the source dirs + should start. For example, if you specify a source path of + rsync://host/module/foo/bar/./baz/dir with -R, rsync would only + replicate the "baz/dir" part of the source path (note: a trailing + dot dir is unaffected unless it also has a trailing slash). - * Most of the I/O is now buffered, which results in a pretty - large speedup when running under MS Windows. (Craig Barratt) + - Added some new --no-FOO options that make it easier to override + unwanted implied or default options. For example, "-a --no-o" (aka + "--archive --no-owner") can be used to turn off the preservation of + file ownership that is implied by -a. - * Optimizations to the name-handling/comparing code have made - some significant reductions in user-CPU time for large file - sets. + - Added the --chmod=MODE option that allows the destination permissions + to be changed from the source permissions. E.g. --chmod=g+w,o-rwx - * Some variable-type cleanup that makes the code more consistent. + - Allow the --temp-dir option to be specified when starting a daemon, + which sets the default temporary directory for incoming files. - * Reduced memory requirements of hard link preservation. - (J.W. Schultz) + - If --delete is combined with --dirs without --recursive, rsync will + now delete in any directory whose content is being synchronized. - * Implemented a new algorithm for hard-link handling that speeds - up the code significantly. (J.W. Schultz and Wayne Davison) + - The file-count stats that are output by --progress were improved to + better indicate what the numbers mean. For instance, the output: + "(xfer#5, to-check=8383/9999)" indicates that this was transferred + file #5, and we still need to check 8383 files out of 9999 total. - * 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. + - Some minor documentation improvements. - * 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) + - Updated some diffs in the patches dir. - * More optimal data transmission for --hard-links (protocol 28). - - * More optimal data transmission for --checksum (protocol 28). + INTERNAL: - * Less memory is used when --checksum is specified. + - Some buffer sizes were expanded a bit, particularly on systems where + MAXPATHLEN is overly small (e.g. cygwin). - * Less memory is used in the file list (a per-file savings). + - If io_printf() tries to format more data than fits in the buffer, exit + with an error instead of transmitting a truncated buffer. - * 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. + - If a va_copy macro is defined, lib/snprintf.c will use it when defining + the VA_COPY macro. - * 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) + - Reduced the amount of stack memory needed for each level of directory + recursion by nearly MAXPATHLEN bytes. - * 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). + DEVELOPER RELATED: - * 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. + - Several diffs in the patches dir now use the proper --enable-FOO + configure option instead of --with-FOO to turn on the inclusion of + the newly patched feature. - * Improved the internal uid/gid code to be more portable and - a little more optimized.
