Any non-printable character is + output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash + is now output as "\\". Rsync also uses your locale setting, which + can make it treat fewer high-bit characters as non-printable. + + - If rsync received an empty file list when pulling files, it would + output a "nothing to do" message and exit with a 0 (success) exit + status, even if the remote rsync returned an error (it did not do + this under the same conditions when pushing files). This was changed + to make the pulling behavior the same as the pushing behavior: we + now do the normal end-of-run outputting (depending on options) and + exit with the appropriate exit status. - ENHANCEMENTS: + BUG FIXES: - * Lower memory use and more optimal transfer of data over - the socket (see the INTERNAL section for details). + - A crash bug was fixed when a daemon had its "path" set to "/", did + not have chroot enabled, and used some anchored excludes in the + rsyncd.conf file. - * The RSYNC_PROXY environment variable can now contain a - "USER:PASS@" prefix before the "HOST:PORT" information. - (Bardur Arantsson) + - Fixed a bug in the transfer of a single file when -H is specified + that might have caused an infinite loop or perhaps a crash. - * 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. + - Fixed a case where the generator might try to tweak the write + permissions of a read-only directory in list-only mode. - * The configure script now accepts --with-rsyncd-conf=PATH - to override the default value of the /etc/rsyncd.conf file. + - If --compare-dest or --link-dest uses a locally-copied file as the + basis for an updated version, log this better when --verbose or -i + is in effect. - * Added a couple extra diffs in the "patches" dir, removed the - ones that got applied, and rebuilt the rest. + - Fixed the accidental disabling of --backup during the --delete-after + processing. - BUG FIXES: + - Restored the ability to use the --address option in client mode (in + addition to its use in daemon mode). + + - Make sure that some temporary progress information from the delete + processing does not get left on the screen when it is followed by a + newline. + + - When --existing skips a directory with extra verbosity, refer to it + as a "directory", not a "file". + + - When transferring a single file to a different-named file, any + generator messages that are source-file related no longer refer to + the file by the destination filename. + + - Fixed a bug where hard-linking a group of files might fail if the + generator hasn't created a needed destination directory yet. + + - Fixed a bug where a hard-linked group of files that is newly-linked + to a file in a --link-dest dir doesn't link the files from the rest + of the cluster. + + - When deleting files with the --one-file-system (-x) option set, rsync + no longer tries to remove files from inside a mount-point on the + receiving side. + + - Fixed a compatibility problem when using --cvs-ignore (-C) and + sending files to an older rsync without using --delete. + + - Make sure that a "- !" or "+ !" include/exclude pattern does not + trigger the list-clearing action that is reserved for "!". - * 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. + - Avoid a timeout in the generator when the sender/receiver aren't + handling the generator's checksum output quickly enough. - * 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 the ommission of some directories in the delete processing when + --relative (-R) was combined with a source path that had a trailing + slash. - * 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. + - Make sure that --max-size doesn't affect a device or a symlink. - * Fixed a byte-order problem in --batch-mode on big-endian - machines. (Jay Fenlason) + - Make sure that a system with a really small MAXPATHLEN does not cause + the buffers in readfd_unbuffered() to be too small to receive normal + messages. (This mainly affected Cygwin.) - * Fixed configure bug when running "./configure --disable-ipv6". + - If a source filename ends with "..", treat it as if "../" had been + specified (so that we don't copy files to the parent dir of the + destination). - * Fixed "make test" bug when build dir is not the source dir. + - If --delete is combined with a file-listing rsync command (i.e. no + transfer is happening), avoid outputting a warning that we couldn't + delete anything. - * 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). The - items are also now properly word-split and parsed without - any +/- prefix munging. + - If --stats is specified with --delete-after, ensure that all the + "deleting" messages are output before the statistics. - * 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). + - Improved one "if" in the deletion code that was only checking errno + for ENOTEMPTY when it should have also been checking for EEXIST. + + ENHANCEMENTS: - * 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. + - Added the --only-write-batch=FILE option that may be used (instead + of --write-batch=FILE) to create a batch file without doing any + actual updating of the destination. This allows you to divert all + the file-updating data away from a slow data link (as long as you + are pushing the data to the remote server when creating the batch). - * Fixed the "refuse options" setting in the rsyncd.conf file. + - When the generator is taking a long time to fill up its output buffer + (e.g. if the transferred files are few, small, or missing), it now + periodically flushes the output buffer so that the sender/receiver + can get started on the files sooner rather than later. - * 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. + - Improved the keep-alive code to handle a long silence between the + sender and the receiver that can occur when the sender is receiving + the checksum data for a large file. - * 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). + - Improved the auth-errors that are logged by the daemon to include + some information on why the authorization failed (wrong user, + password mismatch, etc.). (The client-visible message is unchanged.) - * Fixed compilation problem on Tru64 Unix (having to do with - sockaddr.sa_len and sockaddr.sin_len). + - Improved the client's handling of an "@ERROR" from a daemon so that + it does not complain about an unexpectedly closed socket (since we + really did expect the socket to close). - * Fixed a compatibility problem interacting with older rsync - versions that might send us an empty suffix without telling us - about the backup-dir. + - If the daemon can't open the log-file specified in rsyncd.conf, fall + back to using syslog (and log an appropriate warning). This is + better than what was typically a totally silent failure (since a + daemon is not usually run with the --no-detach option that was + necessary to see the error on stderr). - * 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. + - The man pages now consistently refer to an rsync daemon as a "daemon" + to distinguish it from a server in a non-daemon transfer. - * Fixed the ability to request an empty backup suffix when - sending files to an rsync daemon. + - Made a small change to the rrsync script (restricted rsync -- in the + support dir) to make a read-only server reject all --remove-* options + when sending files (to future-proof it against the possibility of + other similar options being added at some point). INTERNAL: - * Most of the I/O is now buffered, which results in a pretty - large speedup when running under MS Windows. (Craig Barratt) + - Rsync now calls setlocale(LC_CTYPE, "") to enable isprint() to better + discern which filename characters need to be escaped in messages. - * Optimizations to the name-handling/comparing code have made - some significant reductions in user-CPU time for large file - sets. + - Improved the naming of the log-file open/reopen/close functions. - * Some variable-type cleanup that makes the code more consistent. + - Removed some protocol compatibility code that was only needed to help + someone running a pre-release of 2.6.4. - * Reduced memory requirements of hard link preservation. - (J.W. Schultz) + BUILD CHANGES: - * Implemented a new algorithm for hard-link handling that speeds - up the code significantly. (J.W. Schultz and Wayne Davison) + - Fixed a bug in the SUPPORT{,_HARD}_LINKS defines which prevented + rsync from being built without symlink or hard-link support. - * 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. + - You can use --disable-locale to turn off any use of setlocale(). + + - Configure now disables the use of mkstemp() under HP-UX (since they + refuse to fix its broken handling of large files). + + - Configure now explicitly checks for the lseek64() function so that + the code can use HAVE_LSEEK64 instead of inferring lseek64()'s + presence based on the presence of the off64_t type. + + - Some minor enhancements to the test scripts. - * 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 (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. - - * Device numbers are now sent as separate major/minor values - with 32-bit accuracy for each one (protocol 28). Previously - hard-link device data was sent as a single 64-bit number, and - 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. Note that optimizations in the binary - protocol often sends the device data using fewer bytes than - before, even though more precision is now available. - - * Some cleanup of the exclude/include structures and its code - made things clearer, simpler, and more efficient. + - Added a few new diffs to the patches dir, including a patch that + enables the optional copying of extended attributes.
