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. + - The --dry-run option (-n) now mentions changes in directories (w/-v). + It also now includes the normal uptodate output information for -vv. - * Fixed a byte-order problem in --batch-mode on big-endian - machines. (Jay Fenlason) + - Avoid a mkdir warning when removing a directory in the destination + that already exists in the --backup-dir. - * Fixed configure bug when running "./configure --disable-ipv6". + - 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 derived from the cygwin's rsync package.) - * Fixed "make test" bug when build dir is not the source dir. + - Fixed a potential hang when verbosity is high, the client side is + the sender, and the file-list is large. - * 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). + - 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. - * 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 an off-by-one error in the handling of --max-delete=N. - * 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. + - One place in the code wasn't checking if fork() failed. - * Fixed the "refuse options" setting in the rsyncd.conf file. + - The "ignore nonreadable" daemon parameter no longer affects symlinks + that are being copied, even if they point nowhere. - * 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 remaped - mount of the original filesystem could get discovered on a - disk we should be ignoring. + - 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. - * 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). + - 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. - * Fixed compilation problem on Tru64 Unix (having to do with - sockaddr.sa_len and sockaddr.sin_len). + - When --backup was specified with --partial-dir=DIR (where DIR is a + relative path), the backup code was erroneously trying to backup a + file that was put into the partial-dir. - * Fixed a compatibility problem interacting with older rsync - versions that might send us an empty suffix without telling us - about the backup-dir. + - One call to flush_write_file() was not being checked for an error. - * 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. - - INTERNAL: + - The --no-relative option was not being sent from the client to a + server sender. - * Most of the I/O is now buffered, which results in a pretty - large speedup when running under MS Windows. (Craig Barratt) + - If an rsync daemon specified "dont compress = ..." for a file and the + client tried to specify --compress, the libz code was not handling a + compression level of 0 properly. This could cause a transfer failure + if the block-size for a file was large enough (i.e. rsync might have + exited with an error for large files). - * 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) + ENHANCEMENTS: - * More optimal data transmission for --hard-links (protocol 28). + - Rsync now supports popt's option aliases, which means that you can + use /etc/popt and/or ~/.popt to create your own option aliases. + + - Added the --delete-during (--del) option which will delete files + from on the receiving side incrementally as each directory in the + transfer is being processed (which makes it more efficient than the + default, before-the-transfer behavior of --delete). Note that the + --del option is implemented as an internally-defined popt alias, so + an rsync daemon that refuses "delete" (which, for safety's sake, + really matches "delete*") will still refuse all delete options. + + - Added the --copy-dest option, which works like --link-dest except + that it includes copies of identical files. + + - 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.) + + - Added the --max-size option. (Promoted from the patches dir.) + + - 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. + + - The --bwlimit option may now be used in combination with --daemon + to specify both a default value for the daemon side and a value + that cannot be exceeded by a user-specified --bwlimit option. + + - Added the "port" parameter to the rsyncd.conf file. (Promoted from + the patches dir.) Also added "address". + + - 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. + + - Added the --dirs (-d) 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). This option is used automatically when a + modern rsync speaks to a modern daemon, but may also be specified + manually if you want to force the use of the --list-only option over + a remote-shell connection. + + - Added the --omit-dir-times (-O) option which will avoid updating the + modified time for directories when --times was specified. This + option will avoid an extra pass through the file-list at the end of + the transfer (to tweak all the directory times), which can result in + an appreciable speedup for a really large transfer. + + - Added the --filter (-f) option and its helper option, -F. Filter + rules are an extension to the existing include/exclude handling + that also supports nested filter files as well as per-directory + filter files (like .cvsignore, but with full filter-rule parsing). + This new option was chosen in order to ensure that all existing + include/exclude processing remained 100% compatible with older + versions. + + - Added the --delay-updates option that puts all updated files into + a temporary directory (by default ".~tmp~", but settable via the + --partial-dir=DIR option) until the end of the transfer. This + makes the updates a little more atomic for a large transfer. + + - If rsync is put into the background, any output from --progress is + reduced. + + SUPPORT FILES: + + - 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 and a parallel hierarchy of files to effect its update. + + - Added support/mnt-excl that takes the /proc/mounts file and + translates it into a set of excludes that will exclude all mount + points (even mapped mounts to the same disk). The excludes are made + relative to the specified source dir and properly anchored. + + - Added support/savetransfer.c -- a C program that can make a copy of + all the data that flows over the wire. This lets you test for data + corruption (by saving the data on both the sending side and the + receiving side) or provides a way to help debug a protocol error. + + - Added support/rrsync -- my version of Joe Smith's restricted rsync + perl script. This helps to ensure that only certain rsync commands + can be run by an ssh invocation. - * More optimal data transmission for --checksum (protocol 28). + INTERNAL: - * Less memory is used when --checksum is specified. + - Added better checking of the checksum-header values that come over + the socket. - * Less memory is used in the file list (a per-file savings). + - Merged the various delete-file functions into a single function so + that it is easier to maintain. - * 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. + - Improved the type of some variables (particularly blocksize vars) for + consistency and proper size. - * 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) + - Got rid of the uint64 type (which we didn't need). - * 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). + BUILD CHANGES: - * 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. + - Handle an operating system that use mkdev() in place of makedev(). - * Improved the internal uid/gid code to be more portable and - a little more optimized. + - Improved configure to better handle cross-compiling.
