Only affects a daemon if it allows uploads and does not refuse + the --compress option. - * The RSYNC_PROXY environment variable can now contain a - "USER:PASS@" prefix before the "HOST:PORT" information. - (Bardur Arantsson) + BUG FIXES: - * 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. + - The setting of flist->high in clean_flist() was wrong for an empty list. + This could cause flist_find() to crash in certain rare circumstances + (e.g. if just the right directory setup was around when --fuzzy was + combined with --link-dest). - * The configure script now accepts --with-rsyncd-conf=PATH - to override the default value of the /etc/rsyncd.conf file. + - The outputting of hard-linked files when verbosity was > 1 was not right: + without -i it would output the name of each hard-linked file as though + it had been changed (it now outputs a "is hard linked" message for the + file); with -i it would output all dots for the unchanged attributes of + a hard-link (it now changes those dots to spaces, as is done for other + totally unchanged items). - * Added a couple extra diffs in the "patches" dir, removed the - ones that got applied, and rebuilt the rest. + - When backing up a changed symlink or device, get rid of any old backup + item so that we don't get an "already exists" error. - BUG FIXES: + - A couple places that were comparing a local and a remote modification- + time were not honoring the --modify-window option. - * 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 really old, minor bug that could cause rsync to warn about being + unable to mkdir() a path that ends in "/." because it just created the + directory (required --relative, --no-implied-dirs, a source path that + ended in either a trailing slash or a trailing "/.", and a non-existing + destination dir to tickle the bug in a recent version). + + - If the user specifies a remote-host for both the source and destination, + we now output a syntax error rather than trying to open the destination + hostspec as a filename. + + ENHANCEMENTS: - * 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. + - Made the "max verbosity" setting in the rsyncd.conf file settable on a + per-module basis (which now matches the documentation). - * Fixed a byte-order problem in --batch-mode on big-endian - machines. (Jay Fenlason) + - The support/rrsync script has been upgraded to verify the args of options + that take them (instead of rejecting any such options). The script was + also changed to try to be more secure and to fix a problem in the parsing + of a pull operation that has multiple sources. - * Fixed configure bug when running "./configure --disable-ipv6". + - Upgraded the zlib code from 1.1.4 to 1.2.2 (plus the security fix + mentioned above). - * Fixed "make test" bug when build dir is not the source dir. + BUILD CHANGES: - * 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. - - * 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 an option (such as - --link-dest) would get munged into relative path if chroot was not - on, making the option fairly useless. Rsync now transforms the - path into one that is based on the module's root dir, just as if - chroot were 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. - - 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. + - Made configure define NOBODY_USER (currently hard-wired to "nobody") and + NOBODY_GROUP (set to either "nobody" or "nogroup" depending on what we + find in the /etc/group file). - * 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. Note that optimizations - in the binary protocol often sends the device data using fewer - bytes than before, even though more precision is now available. + - Added a test to the test suite, itemized.test, that tests the output of + -i (log-format w/%i) and some double-verbose messages. - * Some cleanup of the exclude/include structures and its code - made things clearer, simpler, and more efficient.
