Also improved the error reporting if the building + of rounding.h fails. - * 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. + - Fixed the use of the --protect-args (-s) option when talking to a daemon. - * 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 --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. - * 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 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. - * Fixed a byte-order problem in --batch-mode on big-endian - machines. (Jay Fenlason) + - Avoid setting the modify time on a directory that already has the right + modify time set. This avoids tweaking the dir's ctime. - * Fixed configure bug when running "./configure --disable-ipv6". + - 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. - * Fixed "make test" bug when build dir is not the source dir. + - Fixed some glitches with the dry-run code's missing-directory + handling, including a problem when combined with --fuzzy. - * 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. + - Fixed some glitches with the skipped-directory handling. - * 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 the 'T'-flag itemizing of symlinks when --time isn't preserved. - * 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 a glitch in the itemizing of permissions with the -E option. - * Fixed the "refuse options" setting in the rsyncd.conf file. + - 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.). - * 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. + - 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. - * 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). + - 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. + + - 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). + + - Fixed the inclusion of per-dir merge files from implied dirs. + + - 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: - * Fixed compilation problem on Tru64 Unix (having to do with - sockaddr.sa_len and sockaddr.sin_len). + - 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). - * Fixed a compatibility problem interacting with older rsync - versions that might send us an empty suffix without telling us - about the backup-dir. + - 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. - * 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. + - Added a few more --no-OPTION overrides. - * Fixed the ability to request an empty backup suffix when - sending files to an rsync daemon. + - Improved the documentation of the --append option. + + - Improved the documentation of the filter/exclude/include daemon + parameters. 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. - - * Some variable-type cleanup that makes the code more consistent. - - * Reduced memory requirements of hard link preservation. - (J.W. Schultz) - - * Implemented a new algorithm for hard-link handling that speeds - up the code significantly. (J.W. Schultz and Wayne Davison) - - * 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. - - * 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. + - 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 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.) + + - 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. + + DEVELOPER RELATED: + + - 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. + + - The configure script now has better checks for figuring out if the + included popt code should be used or not. + + - 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. + + - Updated the testsuite to verify that various bug fixes remain fixed. + + - 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. + + - Updated the build scripts to work with a revised FTP directory + structure.
