This fix ensures that we ask for the right file-list item - when requesting changes from the sender. + - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3 + was only treating it as a special token in an rsync include/exclude + file). - - Rsync now checks the return value of the close() function to - better report disk-full problems on an NFS file system. + - Avoid a mkdir warning when removing a directory in the destination + that already exists in the --backup-dir. - - Restored the old daemon-server behavior of logging error messages - rather than returning them to the user. (A better long-term fix - will be sought in the future.) + - An OS that has a binary mode for its files (such as cygwin0 needed + setmode(fd, O_BINARY) called on the temp-file we opened with + mkstemp(). (Fix picked up from the cygwin package.) - - An obscure uninitialized-variable bug was fixed in the uid/gid - code. (This bug probably had no ill effects.) + - Fixed a potential hang when verbosity is high, the client side is + the sender, and the file-list is large. - - Got rid of the configure check for sys/sysctl.h (it wasn't used - and was causing a problem on some systems). + - We now check if the OS doesn't support using mknod() for creating + FIFOs and sockets, and compile-in using mkfifo() and socket() when + necessary. - ENHANCEMENTS: + - Fixed an off-by-one error in the handling of --max-delete=N. + + - One place in the code wasn't checking if fork() failed. - - Two new diffs were added to the patches dir. + - The "ignore nonreadable" daemon parameter no longer affects symlinks + that are being copied, even if they point nowhere. - -NEWS for rsync 2.6.1 (26 Apr 2004) -Protocol: 28 (changed) -Changes since 2.6.0: + - If the OS does not have lchown() and its chown() tries to set the + referent of a symlink (as it should), we no longer try to set the + user and group of a symlink. - SECURITY FIXES: + - The generator now properly runs the hard-link loop and the dir-time + rewriting loop after we're sure that the redo phase is complete. - - Paths sent to an rsync daemon are more thoroughly sanitized when - chroot is not used. If you're running a non-read-only rsync - daemon with chroot disabled, *please upgrade*, ESPECIALLY if the - user privs you run rsync under is anything above "nobody". + - When --backup was specified with --partial-dir=DIR, don't try to + backup a file in DIR when DIR is relative. ENHANCEMENTS: - - Lower memory use, more optimal transfer of data over the socket, - and lower CPU usage (see the INTERNAL section for details). + - Rsync now supports popt's option aliases, which means that you can + use /etc/popt and/or ~/.popt to create your own option aliases. - - The RSYNC_PROXY environment variable can now contain a - "USER:PASS@" prefix before the "HOST:PORT" information. - (Bardur Arantsson) + - Added the --copy-dest option, which works like --link-dest except + that it includes copies of identical files. - - 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. + - Added support for specifying multiple --compare-dest, --copy-dest, or + --link-dest options, but only of a single type. (Promoted from the + patches dir and enhanced.) - - The configure script now accepts --with-rsyncd-conf=PATH to - override the default value of the /etc/rsyncd.conf file. + - Added the --max-size option. (Promoted from the patches dir.) - - Added a couple extra diffs in the "patches" dir, removed the ones - that got applied, and rebuilt the rest. + - The daemon-mode options were separated from the normal rsync options + so that they can't be mixed together. This makes it impossible to + start a daemon that had improper default option values that could + cause problems (such as a hang or an abort) when a client connects. - - Documentation changes now attempt to describe some often mis- - understood features more clearly. + - The --bwlimit option may now be used in combination with --daemon + to specify a default value for the daemon side and also a value + that cannot be exceeded by a user-specified --bwlimit option. - BUG FIXES: + - Added the "port" parameter to the rsyncd.conf file. (Promoted from + the patches dir.) + + - In _exit_cleanup(): when we are exiting with a partially-received + file, we now flush any data in the write-cache before closing the + partial file. + + - The --inplace support was enhanced to work with --compare-dest, + --link-dest, and (the new) --copy-dest options. - - 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 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 a byte-order problem in --batch-mode on big-endian machines. - (Jay Fenlason) - - - Fixed configure bug when running "./configure --disable-ipv6". - - - Fixed "make test" bug when build dir is not the source dir. - - - When using --cvs-exclude, the exclude items we get from a - per-directory's .cvsignore file once again only affect that one - directory (not all following directories too). The items are also - now properly word-split and parsed without any +/- prefix parsing. - - - 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 a option (such as - --link-dest) would get its absolute path munged into a relative - one if chroot was not on, making that setting fairly useless. - Rsync now transforms the path into one that is based on the - module's base dir when chroot is not 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. + - Added the --dirs option for an easier way to copy directories + without recursion. + + - Added the --list-only option which is mainly a way for the client to + put the server into listing mode without needing to resort to any + option kluges (e.g. the age-old use of "-r --exclude="/*/*" for a + non-recursive listing). + + - Added support/atomic-rsync -- a perl script that will transfer some + files using rsync, and then move the updated files into place all at + once at the end of the transfer. Only works when pulling, and uses + --link-dest. 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 cleanup of the variable types make 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 (which mainly affected hard-link messages and - verbose --stats output). - - - Improved the internal uid/gid code to be more portable and a - little more optimized. - - - 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 (with both ends of the - connection are using protocol 28). Note that optimizations in the - binary protocol for sending the device numbers often results in - fewer bytes being used than before, even though more precision is - now available. - - - Some cleanup of the exclude/include structures and its code made - things clearer (internally), simpler, and more efficient. - - - 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. (Note that the - batch code is still considered to be experimental.) + - Added better checking of the checksum header values that come over + the socket. + + - Improved the type of some variables for consistency and proper size. + + BUILD CHANGES: + + - Handle an operating system that use mkdev() in place of makedev().
