BUG FIXES: - * 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). + - Fixed a crash bug when a single-use rsync daemon (via remote shell) was + run without specifying a --config=FILE option. - * 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. + - Fixed a crash when backing up a directory that has a default ACL. - * 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 a bug in the handling of xattr values that could cause rsync to + not think that a file's extended attributes are up-to-date. - * 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 working of --fake-super with --link-dest and --xattrs. - * Fixed the "refuse options" setting in the rsyncd.conf file. + - Fixed a hang when combining --dry-run with --remove-source-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 both). + - Fixed a bug with --iconv's handling of files that cannot be converted: + a failed name can no longer cause a transfer failure. - 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. (Wayne Davison) + - Fixed the building of the rounding.h file on systems that need custom + CPPFLAGS to be used. Also improved the error reporting if the building + of rounding.h fails. - * Some variable-type cleanup that makes the code more consistent. - (Wayne Davison) + - Fixed the use of the --protect-args (-s) option when talking to a daemon. - * Reduced memory requirements of hard link preservation. - (J.W. Schultz) + - Fixed the --ignore-existing option's protection of files on the receiver + that are non-regular files on the sender (e.g. if a symlink or a dir on + the sender is trying to replace a file on the receiver). The reverse + protection (protecting a dir/symlink/device from being replaced by a + file) was already working. - * Implemented a new algorithm for hard-link handling that speeds - up the code significantly. (J.W. Schultz and Wayne Davison) + - Fixed an assert failure if --hard-links is combined with an option that + can skip a file in a set of hard-linked files (i.e. --ignore-existing, + --append, etc.), without skipping all the files in the set. - * 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. + - Avoid setting the modify time on a directory that already has the right + modify time set. This avoids tweaking the dir's ctime. - * 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) + - Improved the daemon-exclude handling to do a better job of applying the + exclude rules to path entries. It also sends the user an error just as + if the files were actually missing (instead of silently ignoring the + user's args), and avoids sending the user the filter-action messages + for these non-user-initiated rules. - * More optimal data transmission for --hard-links (protocol 28). + - Fixed some glitches with the dry-run code's missing-directory + handling, including a problem when combined with --fuzzy. - * More optimal data transmission for --checksum (protocol 28). + - Fixed some glitches with the skipped-directory handling. - * Less memory is used when --checksum is specified. + - Fixed the 'T'-flag itemizing of symlinks when --time isn't preserved. - * Less memory is used in the file list (a per-file savings). + - Fixed a glitch in the itemizing of permissions with the -E option. - * 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) + - The --append option's restricting of transfers to those that add data no + longer prevents the updating of non-content changes to otherwise up-to- + date files (i.e. those with the same content but differing permissions, + ownership, xattrs, etc.). - * 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) + - Don't allow --fake-super to be specified with -XX (double --xattrs) + because the options conflict. If a daemon has "fake super" enabled, + it automatically downgrades a -XX request to -X. - * 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. + - Fixed a couple bugs in the parsing of daemon-config excludes that could + make a floating exclude rule get treated as matching an absolute path. - * 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). + - A daemon doesn't try to auto-refuse the "iconv" option if iconv-support + wasn't compiled in to the daemon (avoiding a warning in the logs). - * Improved the internal uid/gid code to be more portable and - a little more optimized. + - Fixed the inclusion of per-dir merge files from implied dirs. - -NEWS for rsync 2.6.0 (1 Jan 2004) -Protocol: 27 (changed) -Changes since 2.5.7: + - Fixed the support/rrsync script to work with the latest options that + rsync sends (including its flag-specifying use of -e to the server). 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. + - Added the --old-dirs (--old-d) option to make it easier for a user to + ask for file-listings with older rsync versions (this is easier than + having to type "-r --exclude='/*/*'" manually). - 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) - - * 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 getting an error while asking an older rsync daemon for a file + listing, rsync will try to notice if the error is a rejection of the + --dirs (-d) option and let the user know how to work around the issue. - * 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) + - Added a few more --no-OPTION overrides. - * Keep tmp names from overflowing MAXPATHLEN. + - Improved the documentation of the --append option. - * Make --link-dest honor the absence of -p, -o, and -g. + - Improved the documentation of the filter/exclude/include daemon + parameters. - * Made rsync treat a trailing slash in the destination in a more - consistent manner. - - * Fixed file I/O error detection. (John Van Essen) - - * 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. - - * 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) + - Fixed a couple minor bugs in the included popt library (ones which I + sent to the official popt project for inclusion in the 1.14 release). - * Fixed some bugs in the handling of --delete and --exclude when - using the --relative (-R) option. (Wayne Davison) + - Fixed a stat() call that should have been do_stat() so that the proper + normal/64-bit stat() function gets called. (Was in an area that should + not have caused problems, though.) - * 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) + - Changed the file-glob code to do a directory scan without using the + "glob" and "glob.h". This lets us do the globbing with less memory + churn, and also avoid adding daemon-excluded items to the returned + args. - * 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) + DEVELOPER RELATED: - * Added a fix that should give ssh time to restore the tty settings - if the user presses Ctrl-C at an ssh password prompt. + - The configure script tries to get the user's compiler to not warn about + unused function parameters if the build is not including one or more of + the ACL/xattrs/iconv features. - INTERNAL: + - The configure script now has better checks for figuring out if the + included popt code should be used or not. - * Eliminated vestigial support for old versions that we stopped - supporting. (J.W. Schultz) + - Fixed two testsuite glitches: avoid a failure if someone's "cd" command + outputs the current directory when cd-ing to a relative path, and made + the itemized test query how rsync was built to determine if it should + expect hard-linked symlinks or not. - * Simplified some of the option-parsing code. (Wayne Davison) + - Updated the testsuite to verify that various bug fixes remain fixed. - * Some cleanup made to the exclude code, as well as some new - defines added to enhance readability. (Wayne Davison) + - The RPM spec file was updated to have: (1) comments for how to use the + rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file. - * 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) + - Updated the build scripts to work with a revised FTP directory + structure.
