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're processed. + - Fixed a case where the generator might try to tweak the write + permissions of a read-only directory in list-only mode. - BUG FIXES: + - 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. - * When -x (--one-file-system) is combined with -L (--copy-links) - or --copy-unsafe-links, no symlinked files are skipped, even - if the referant file is on a different filesystem. - - * The --link-dest code now works properly for a non-root user - when the UIDs of the source and destination differ and -o was - specified, and when the group of the source can't be used on - the destination and -g was specified. (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. + - Fixed the accidental disabling of --backup during the --delete-after + processing. - INTERNAL: + - Restored the ability to use the --address option in client mode (in + addition to its use in daemon mode). - * Most of the I/O is now buffered, which results in a pretty - large speedup when running under MS Windows. (Craig Barratt) + - 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. - * Optimizations to the name-handling/comparing code have made - some significant reductions in user-CPU time for large file - sets. (Wayne Davison) + - When --existing skips a directory with extra verbosity, refer to it + as a "directory", not a "file". - * Some variable-type cleanup that makes the code more consistent. - (Wayne Davison) + - 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. - * Reduced memory requirements of hard link preservation. - (J.W. Schultz) + - Fixed a bug where hard-linking a group of files might fail if the + generator hasn't created a needed destination directory yet. - * Implemented a new algorithm for hard-link handling that speeds - up the code significantly. (J.W. Schultz and Wayne Davison) + - 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. - * 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 + - 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. - * Got rid of support for protocol versions 17 and 18 (which are - both over 6 years old). (Wayne Davison) + - Fixed a compatibility problem when using --cvs-ignore (-C) and + sending files to an older rsync without using --delete. - * More optimal data transmission for --hard-links (protocol 28). + - Make sure that a "- !" or "+ !" include/exclude pattern does not + trigger the list-clearing action that is reserved for "!". - * More optimal data transmission for --checksum (protocol 28). + - Avoid a timeout in the generator when the sender/receiver aren't + handling the generator's checksum output quickly enough. - * Less memory is used when --checksum is 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. - * Less memory is used in the file list (a per-file savings). + - Make sure that --max-size doesn't affect a device or a symlink. - * 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) + - 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.) - * 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) + - 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). - * 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. + - 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. - * 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). + - If --stats is specified with --delete-after, ensure that all the + "deleting" messages are output before the statistics. - * 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 2.5.7: + - Improved one "if" in the deletion code that was only checking errno + for ENOTEMPTY when it should have also been checking for EEXIST. ENHANCEMENTS: - * "ssh" is now the default remote shell for rsync. If you want to - change this, configure like this: "./configure --with-rsh=rsh". - - * Added --files-from, --no-relative, --no-implied-dirs, and --from0. - Note that --from0 affects the line-ending character for all the - files read by the --*-from options. (Wayne Davison) - - * Length of csum2 is now per-file starting with protocol version - 27. (J.W. Schultz) - - * Per-file dynamic block size is now sqrt(file length). The - per-file checksum size is determined according to an algorithm - provided by Donovan Baarda which reduces the probability of rsync - algorithm corrupting data and falling back using the whole md4 - checksums. (J.W. Schultz, Donovan Baarda) - - * The --stats option no longer includes the (debug) malloc summary - unless the verbose option was specified at least twice. - - * Added a new error/warning code for when files vanish from the - sending side. Made vanished source files not interfere with the - file-deletion pass when --delete-after was specified. - - * Various trailing-info sections are now preceded by a newline. - - BUG FIXES: - - * Fixed several exclude/include matching bugs when using wild-cards. - This has a several user-visible effects, all of which make the - matching more consistent and intuitive. This should hopefully not - cause anyone problems since it makes the matching work more like - what people are expecting. (Wayne Davison) - - - A pattern with a "**" no longer causes a "*" to match slashes. - For example, with "/*/foo/**", "foo" must be 2 levels deep. - [If your string has BOTH "*" and "**" wildcards, changing the - "*" wildcards to "**" will provide the old behavior in all - versions.] - - - "**/foo" now matches at the base of the transfer (like /foo - does). [Use "/**/foo" to get the old behavior in all versions.] - - - A non-anchored wildcard term floats to match beyond the base of - the transfer. E.g. "CVS/R*" matches at the end of the path, - just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*" - to get the old behavior in all versions.] - - - Including a "**" in the match term causes it to be matched - against the entire path, not just the name portion, even if - there aren't any interior slashes in the term. E.g. "foo**bar" - would exclude "/path/foo-bar" (just like before) as well as - "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the - old behavior in all versions.] - - * The exclude list specified in the daemon's config file is now - properly applied to the pulled items no matter how deep the - user's file-args are in the source tree. (Wayne Davison) - - * For protocol version >= 27, mdfour_tail() is called when the - block size (including checksum_seed) is a multiple of 64. - Previously it was not called, giving the wrong MD4 checksum. - (Craig Barratt) + - 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). - * For protocol version >= 27, a 64 bit bit counter is used in - mdfour.c as required by the RFC. Previously only a 32 bit bit - counter was used, causing incorrect MD4 file checksums for - file sizes >= 512MB - 4. (Craig Barratt) + - 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. - * Fixed a crash bug when interacting with older rsync versions and - multiple files of the same name are destined for the same dir. - (Wayne Davison) + - 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. - * Keep tmp names from overflowing MAXPATHLEN. + - 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.) - * Make --link-dest honor the absence of -p, -o, and -g. + - 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). - * Made rsync treat a trailing slash in the destination in a more - consistent manner. + - 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). - * Fixed file I/O error detection. (John Van Essen) + - 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 bogus "malformed address {hostname}" message in rsyncd log - when checking IP address against hostnames from "hosts allow" - and "hosts deny" parameters in config file. + - 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). - * Print heap statistics when verbose >= 2 instead of when >= 1. - - * Fixed a compression (-z) bug when syncing a mostly-matching file - that contains already-compressed data. (Yasuoka Masahiko and - Wayne Davison) - - * Fixed a bug in the --backup code that could cause deleted files - to not get backed up. - - * When the backup code makes new directories, create them with mode - 0700 instead of 0755 (since the directory permissions in the - backup tree are not yet copied from the main tree). - - * Call setgroups() in a more portable manner. + INTERNAL: - * Improved file-related error messages to better indicate exactly - what pathname failed. (Wayne Davison) + - Rsync now calls setlocale(LC_CTYPE, "") to enable isprint() to better + discern which filename characters need to be escaped in messages. - * Fixed some bugs in the handling of --delete and --exclude when - using the --relative (-R) option. (Wayne Davison) + - Improved the naming of the log-file open/reopen/close functions. - * Fixed bug that prevented regular files from replacing - special files and caused a directory in --link-dest or - --compare-dest to block the creation of a file with the - same path. A directory still cannot be replaced by a - regular file unless --delete specified. (J.W. Schultz) + - Removed some protocol compatibility code that was only needed to help + someone running a pre-release of 2.6.4. - * Detect and report when open or opendir succeed but read and - readdir fail caused by network filesystem issues and truncated - files. (David Norwood, Michael Brown, J.W. Schultz) + BUILD CHANGES: - * Added a fix that should give ssh time to restore the tty settings - if the user presses Ctrl-C at an ssh password prompt. + - Fixed a bug in the SUPPORT{,_HARD}_LINKS defines which prevented + rsync from being built without symlink or hard-link support. - INTERNAL: + - You can use --disable-locale to turn off any use of setlocale(). - * Eliminated vestigial support for old versions that we stopped - supporting. (J.W. Schultz) + - Configure now disables the use of mkstemp() under HP-UX (since they + refuse to fix its broken handling of large files). - * Simplified some of the option-parsing code. (Wayne Davison) + - 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 cleanup made to the exclude code, as well as some new - defines added to enhance readability. (Wayne Davison) + - Some minor enhancements to the test scripts. - * Changed the protocol-version code so that it can interact at a - lower protocol level than the maximum supported by both sides. - Added an undocumented option, --protocol=N, to force the value - we advertise to the other side (primarily for testing purposes). - (Wayne Davison) + - Added a few new diffs to the patches dir, including a patch that + enables the optional copying of extended attributes.
