(Note: both sides must be running 2.6.3 for this to + work -- older receivers always keep the file, and older senders + don't tell the receiver that the file was not read correctly.) - BUG FIXES: + - If a file gets resent in a single transfer and the --backup option + is enabled, rsync no longer performs a duplicate backup (losing the + original file in the process). - * 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 an age-old crash problem with --read-batch on a local copy + (rsync was improperly assuming --whole-file for the local copy). - * 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. + - Files specified in the daemon's "exclude" or "exclude from" config + items are now excluded from being uploaded (assuming that the module + allows uploading at all) in addition to the old download exclusion. - * 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. + - Got rid of a potential hang in the receiver when near the end of a + phase. - * Fixed a byte-order problem in --batch-mode on big-endian - machines. (Jay Fenlason) + - When using --backup without a --backup-dir, rsync no longer preserves + the modify time on directories. This avoids confusing NFS. - * Fixed configure bug when running "./configure --disable-ipv6". + - When --copy-links (-L) is specified, we now output a separate error + for a symlink that has no referent instead of claiming that a file + "vanished". - * Fixed "make test" bug when build dir is not the source dir. + - Error messages from the daemon server's option-parsing (such as + refused options) now get sent back to the client (the server used + to just exit because the socket wasn't in the right state to send + the message). - * 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. + - Most errors that occur during a daemon transfer are now returned to + the user in addition to being logged (some messages are intended to + be daemon-only). - * 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 daemon authentication code when using one of the + batch-processing options. - * 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. + - We try to work around some buggy IPv6 implementations that fail to + implement IPV6_V6ONLY. This should fix the "address in use" error + that some daemons get when running on an OS with a buggy IPv6 + implementation. Also, if the new code gets this error, we might + suggest that the user specify --ipv4 or --ipv6 (if we think it will + help). - * Fixed the "refuse options" setting in the rsyncd.conf file. + ENHANCEMENTS: - * 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. + - Added --keep-dirlinks (-K), which allows you to symlink a directory + onto another partition on the receiving side and have rsync treat it + as matching a normal directory from the sender. - * 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). + - Added the "write only" option to the daemon's config file. - * Fixed compilation problem on Tru64 Unix (having to do with - sockaddr.sa_len and sockaddr.sin_len). + - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) + and documented all these options in the man page. - * Fixed a compatibility problem interacting with older rsync - versions that might send us an empty suffix without telling us - about the backup-dir. + - Improved the handling of the --bwlimit option so that it's less + bursty, more accurate, and works properly over a larger range of + values. - * 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. + - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and + SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address. - * Fixed the ability to request an empty backup suffix when - sending files to an rsync daemon. + - Added the --checksum-seed=N option for advanced users. 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. + - Some cleanup in the exclude code has saved some per-exclude memory + and made the code easier to maintain. + + - Improved the argv-overflow checking for a remote command that has + a lot of args. + + - Use rsyserr() in the various places that were still calling + rprintf() with strerror() as an arg. + + - If an rsync daemon is listening on multiple sockets (to handle both + IPv4 and IPv6 to a single port), we now close all the unneeded file + handles after we accept a connection (we used to close just one of + them). + + - Optimized away a loop in hash_search(). + + BUILD CHANGES: + + - Added a "gen" target to rebuild most of the generated files, + including configure, config.h.in, the man pages, and proto.h. + + - If "make proto" doesn't find some changes in the prototypes, the + proto.h file is left untouched (its time-stamp used to always be + updated). + + - The variable $STRIP (that is optionally set by the install-strip + target's rule) was changed to $INSTALL_STRIP because some systems + have $STRIP set in the environment. + + - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined. + + DEVELOPER RELATED: + + - The scripts in the testsuite dir were cleaned up a bit. + + - Some new diffs were added to the patches dir, and some accepted + ones were removed. +
