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. BUG FIXES: - - Fixed a major bug in the sorting of the filenames when --relative - is used for some sources (probably just "/", but don't depend on - that). This fix ensures that we ask for the right file-list item - when requesting changes from the sender. + - 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. - - Rsync now checks the return value of the close() function to - better report disk-full problems on an NFS file system. + - 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. - - Restored the old daemon-server behavior of logging error messages - rather than returning them to the user. (A better long-term fix - will be sought in the future.) + - Fixed a case where the generator might try to tweak the write + permissions of a read-only directory in list-only mode. - - An obscure uninitialized-variable bug was fixed in the uid/gid - code. (This bug probably had no ill effects.) + - 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. - - Got rid of the configure check for sys/sysctl.h (it wasn't used - and was causing a problem on some systems). Also improved the - broken-largefile-locking test to try to avoid failure due to an - NFS build-dir. + - Fixed the accidental disabling of --backup during the --delete-after + processing. - - Fixed a compile problem on systems that don't define - AI_NUMERICHOST. + - Restored the ability to use the --address option in client mode (in + addition to its use in daemon mode). - - Fixed a compile problem in the popt source for compilers that - don't support __attribute__. + - 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. - INTERNAL: + - 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 "!". - - Improved the testsuite's "merge" test to work on OSF1. + - Avoid a timeout in the generator when the sender/receiver aren't + handling the generator's checksum output quickly enough. - - Two new diffs were added to the patches dir. + - Fixed the ommission of some directories in the delete processing when + --relative (-R) was combined with a source path that had a trailing + slash. - -NEWS for rsync 2.6.1 (26 Apr 2004) -Protocol: 28 (changed) -Changes since 2.6.0: + - Make sure that --max-size doesn't affect a device or a symlink. - SECURITY FIXES: + - 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.) - - Paths sent to an rsync daemon are more thoroughly sanitized when - chroot is not used. If you're running a non-read-only rsync - daemon with chroot disabled, *please upgrade*, ESPECIALLY if the - user privs you run rsync under is anything above "nobody". + - 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). + + - 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. + + - If --stats is specified with --delete-after, ensure that all the + "deleting" messages are output before the statistics. + + - Improved one "if" in the deletion code that was only checking errno + for ENOTEMPTY when it should have also been checking for EEXIST. ENHANCEMENTS: - - Lower memory use, more optimal transfer of data over the socket, - and lower CPU usage (see the INTERNAL section for details). + - 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). - - The RSYNC_PROXY environment variable can now contain a - "USER:PASS@" prefix before the "HOST:PORT" information. - (Bardur Arantsson) + - 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. - - 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. + - 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. - - The configure script now accepts --with-rsyncd-conf=PATH to - override the default value of the /etc/rsyncd.conf file. + - 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.) - - Added a couple extra diffs in the "patches" dir, removed the ones - that got applied, and rebuilt the rest. + - 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). - - Documentation changes now attempt to describe some often mis- - understood features more clearly. + - 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). - BUG FIXES: + - The man pages now consistently refer to an rsync daemon as a "daemon" + to distinguish it from a server in a non-daemon transfer. - - 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. - - - 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 - per-directory's .cvsignore file once again only affect that one - directory (not all following directories too). The items are also - now properly word-split and parsed without any +/- prefix parsing. - - - 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 remapped mount of the - original filesystem could get discovered in a subdir 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). - - - Path-specifying options to a daemon should now work the same with - or without chroot turned on. Previously, such a option (such as - --link-dest) would get its absolute path munged into a relative - one if chroot was not on, making that setting fairly useless. - Rsync now transforms the path into one that is based on the - module's base dir when chroot is not enabled. - - - Fixed compilation problem on Tru64 Unix (having to do with - sockaddr.sa_len and sockaddr.sin_len). - - - Fixed a compatibility problem interacting with older rsync - versions that might send us an empty --suffix value without - telling us that --backup-dir was specified. - - - 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. - - - 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 cleanup of the variable types make 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 (which mainly affected hard-link messages and - verbose --stats output). - - - Improved the internal uid/gid code to be more portable and a - little more optimized. - - - The device numbers sent when using --devices are now sent as - separate major/minor values with 32-bit accuracy (protocol 28). - Previously, the 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 (with both ends of the - connection are using protocol 28). Note that optimizations in the - binary protocol for sending the device numbers often results in - fewer bytes being used than before, even though more precision is - now available. - - - Some cleanup of the exclude/include structures and its code made - things clearer (internally), simpler, and more efficient. - - - 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. (Note that the - batch code is still considered to be experimental.) + - Added a few new diffs to the patches dir, including a patch that + enables the optional copying of extended attributes.
