(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.) - - - Fixed an age-old crash problem with --read-batch on a local copy - (rsync was improperly assuming --whole-file for the local copy). - - - Files specified in the daemon's "exclude" or "exclude from" config - items are now excluded from being uploaded (if the module is not - read-only) in addition to the old download exclusion. - - - When using --backup without a --backup-dir, rsync no longer preserves - the modify time on directories. This avoids confusing NFS. - - - Fixed a bug in the daemon authentication code when using one of the - batch-processing options. - - ENHANCEMENTS: - - - Added the "write only" option to the daemon's config file. - - - Added the --checksum-seed=N option for advanced users. - - - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) - and documented all these options in the man page. - - INTERNAL: - - - Some cleanup in the exclude code has saved some per-exclude memory - and made the code easier to maintain. - - - Use rsyserr() in the various places that were still calling - rprintf() with strerror() as an arg. + NOTABLE CHANGE IN BEHAVIOR: - BUILD CHANGES: - - - Added a "gen" target to rebuild most of the various generated - files, including configure, config.h.in, the man pages, and - proto.h. - - - The timestamp of the proto.h file is unaltered by "make proto" - if the contents don't change. - - DEVELOPER RELATED: - - - The scripts in the testsuite dir were cleaned up a bit. - - -NEWS for rsync 2.6.2 (30 Apr 2004) -Protocol: 28 (unchanged) -Changes since 2.6.1: + - The handling of implied directories when using --relative has changed + to send them as directories (e.g. no implied dir is ever sent as a + symlink). This avoids unexpected behavior and should not adversely + affect most people. If you're one of those rare people who relied + upon having an implied dir be duplicated as a symlink, either specify + --keep-dirlinks or --no-implied-dirs. BUG FIXES: - - Fixed a major bug in the sorting of the filenames when --relative - is used for some sources (just sources such as "/" and "/*" were - affected). This fix ensures that we ask for the right file-list - item when requesting changes from the sender. - - - Rsync now checks the return value of the close() function to - better report disk-full problems on an NFS file system. + - Fixed the output of -ii when combined with one of the --*-dest options: + it now itemizes all the items, not just the changed ones. - - 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.) + - Made the output of all file types consistent when using a --*-dest + option. Prior versions used to output too many creation events for + matching items. - - An obscure uninitialized-variable bug was fixed in the uid/gid - code. (This bug probably had no ill effects.) + - The code that waits for a child pid now handles being interrupted by a + signal. This fixes a problem with the pre-xfer exec function not being + able to get the exit status from the script. - BUILD CHANGES: + - A negated filter rule (with a '!' modifier) no longer loses the negation + when sending the filter rules to the remote rsync. - - Got rid of the configure check for sys/sysctl.h (it wasn't used - and was causing a problem on some systems). Also improved the - broken-largefile-locking test to try to avoid failure due to an - NFS build-dir. + - Fixed a problem with the --out-format (aka --log-format) option %f: it + would output superfluous directory information for a non-daemon rsync. - - Fixed a compile problem on systems that don't define - AI_NUMERICHOST. + - Fixed a problem with -vv (double --verbose) and --stats when "pushing" + files (which includes local copies). Version 2.6.9 would complete the + copy, but exit with an error when the receiver output its memory stats. - - Fixed a compile problem in the popt source for compilers that - don't support __attribute__. + - If --password-file is used on a non-daemon transfer, rsync now complains + and exits. This should help users figure out that they can't use this + option to control a remote shell's password prompt. - DEVELOPER RELATED: + - Make sure that directory permissions of a newly-created destination + directory are handled right when --perms is left off. - - Improved the testsuite's "merge" test to work on OSF1. + - The itemized output of a newly-created destination directory is now + output as a creation event, not a change event. - - Two new diffs were added to the patches dir. + - Improved --hard-link so that more corner cases are handled correctly + when combined with options such as --link-dest and/or --ignore-existing. - -NEWS for rsync 2.6.1 (26 Apr 2004) -Protocol: 28 (changed) -Changes since 2.6.0: + - The --append option no longer updates a file that has the same size. - SECURITY FIXES: + - Fixed a bug when combining --backup and --backup-dir with --inplace: + any missing backup directories are now created. - - 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". + - Fixed a bug when using --backup and --inplace with --whole-file or + --read-batch: backup files are actually created now. - ENHANCEMENTS: + - Starting up an extra copy of an rsync daemon does not delete the pidfile + for the running daemon -- if the pidfile exists, the extra program will + exit with an error. - - Lower memory use, more optimal transfer of data over the socket, - and lower CPU usage (see the INTERNAL section for details). + - The daemon pidfile is checked and created sooner in the startup sequence. - - The RSYNC_PROXY environment variable can now contain a - "USER:PASS@" prefix before the "HOST:PORT" information. - (Bardur Arantsson) - - - 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. - - - Documentation changes now attempt to describe some often mis- - understood features more clearly. + ENHANCEMENTS: - BUG FIXES: + - A new incremental-recursion algorithm is now used when rsync is talking + to another 3.x version. This starts the transfer going more quickly + (before all the files have been found), and requires much less memory. + See the --recursive option in the manpage for some restrictions. + + - Saved memory in the non-incremental-recursion algorithm for typical + option values (usually saving from 21-29 bytes per file). + + - The default --delete algorithm is now --delete-during when talking to a + 3.x rsync. This is a faster scan than using --delete-before (which is + the default when talking to older rsync versions), and is compatible with + the new incremental recursion mode. + + - Rsync now allows multiple remote-source args to be specified rather than + having to rely on a special space-splitting side-effect of the remote- + shell. Additional remote args must specify the same host or have an + empty hostname, as seen here: :file1 ::module/file2. This means that + local use of brace expansion now works: rsync -av host:path/{f1,f2} . + + - Added the --delete-delay option, which is a more efficient way to delete + files at the end of the transfer without needing a separate delete pass. + + - Added the --acls (-A) option to preserve Access Control Lists. This is + an improved version of the prior patch that was available, and it even + supports OS X ACLs. (If you need to have backward compatibility with + old, patched versions of rsync, apply the acls.diff file from the patches + dir.) + + - Added the --xattrs (-X) option to preserver extended attributes. This is + an improved version of the prior patch that was available. (If you need + to have backward compatibility with old, patched versions of rsync, apply + the xattrs.diff file from the patches dir.) + + - Added the --fake-super option that allows a non-super user to preserve + all attributes of a file by using a special extended-attribute idiom. + There is also an analogous "fake super" option for an rsync daemon. + + - Added the --iconv option, which allows rsync to convert filenames from + one character-set to another during the transfer. The default is to make + this feature available as long as your system has iconv_open(). If + compilation fails, specify --disable-iconv to configure, and then + rebuild. If you want rsync to perform character-set conversions by + default, you can specify --enable-iconv=CONVERT_STRING with the default + value for the --iconv option that you wish to use. For example, + --enable-iconv=. is a good choice. See the rsync manpage for an + explanation of the --iconv option's settings. + + - Added the --skip-compress=LIST option to override of the default list of + file suffixes that will not be compressed when using --compress. + + - The daemon's default for "dont compress" was extended to include: + *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg + The matching routine was also optimized to run more quickly. - - 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 --max-delete option now outputs a warning if it skipped any file + deletions, including a count of how many deletions were skipped. (Older + versions just silently stopped deleting things.) - - 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. + - You may specify --max-delete=0 to a 3.0.0 client to request that it warn + about extraneous files without deleting anything. If you're not sure + what version the client is, you can use the less-obvious --max-delete=-1, + as both old and new versions will treat that as the same request (though + older versions don't warn). - - 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) - - - 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 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. + - The --hard-link option now uses less memory on both the sending and + receiving side for all protocol versions. For protocol 30, the use of a + hashtable on the sending side allows us to more efficiently convey to the + receiver what files are linked together. This reduces the amount of data + sent over the socket by a considerable margin (rather than adding more + data), and limits the in-memory storage of the device+inode information + to just the sending side for the new protocol 30, or to the receiving + side when speaking an older protocol (note that older rsync versions kept + the device+inode information on both sides). - INTERNAL: + - The filter rules now support a perishable ("p") modifier that marks rules + that should not have an effect in a directory that is being deleted. e.g. + -f '-p .svn/' would only affect "live" .svn directories. - - Most of the I/O is now buffered, which results in a pretty large - speedup when running under MS Windows. (Craig Barratt) + - If we get an error setting the time on a symlink, we don't complain about + it anymore (since some operating systems don't support that, and it's not + that important). - - Optimizations to the name-handling/comparing code have made some - significant reductions in user-CPU time for large file sets. + - Protocol 30 now uses MD5 checksums instead of MD4. - - Some cleanup of the variable types make the code more consistent. + - If a daemon module's "path" value is not an absolute pathname, the code + now makes it absolute internally (making it work properly). - - Reduced memory requirements of hard link preservation. - (J.W. Schultz) + - Changed the --append option to not checksum the existing data in the + destination file, which speeds up file appending. - - Implemented a new algorithm for hard-link handling that speeds up - the code significantly. (J.W. Schultz and Wayne Davison) + - Added the --append-verify option, which works like the older --append + option (verifying the existing data in the destination file). For + compatibility with older rsync versions, any use of --append that is + talking protocol 29 or older will revert to the --append-verify method. - - 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. + - Documented and extended the support for the RSYNC_CONNECT_PROG variable + that can be used to enhance the client side of a daemon connection. - - 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) + - Added the --protect-args (-s) option, that tells rsync to send most of + the command-line args at the start of the transfer rather than as args + to the remote-shell command. This protects them from space-splitting, + and only interprets basic wildcard special shell characters (*?[). - - More optimal data transmission for --hard-links (protocol 28). + - Improved the dashes and double-quotes in the nroff manpage output. - - More optimal data transmission for --checksum (protocol 28). + - We now support a lot more --no-OPTION override options. - - Less memory is used when --checksum is specified. + INTERNAL: - - Less memory is used in the file list (a per-file savings). + - The file-list sorting algorithm now uses a sort that keeps any same- + named items in the same order as they were specified. This allows + rsync to always ensure that the first of the duplicates is the one + that will be included in the copy. The new sort was also faster + than the glibc version of qsort() and mergesort() in my testing. - - 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. + - Rsync now supports the transfer of 64-bit timestamps (time_t values). - - 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) + - Fixed a build problem with older (2.x) versions of gcc. - - 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). + - Added some isType() functions that make dealing with signed characters + easier without forcing variables via casts. - - Improved the internal uid/gid code to be more portable and a - little more optimized. + - Changed strcat/strcpy/sprintf function calls to use safer versions. - - 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. + - Upgraded the included popt version to 1.10.2 and improved its use of + string-handling functions. - - Some cleanup of the exclude/include structures and its code made - things clearer (internally), simpler, and more efficient. + - Added missing prototypes for compatibility functions from the lib dir. - - 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.) + - Configure determines if iconv() has a const arg, allowing us to avoid a + compiler warning. - BUILD CHANGES: + - Made the sending of some numbers more efficient for protocol 30. - - The configure script now accepts --with-rsyncd-conf=PATH to - override the default value of the /etc/rsyncd.conf file. + - Make sure that a daemon process doesn't mind if the client was weird and + omitted the --server option. - - Fixed configure bug when running "./configure --disable-ipv6". + - Improved the use of "const" on pointers. - - Fixed compilation problem on Tru64 Unix (having to do with - sockaddr.sa_len and sockaddr.sin_len). + - Improved J.W.'s pool_alloc routines to add a way of freeing older + sections of a pool's memory. DEVELOPER RELATED: - - Fixed "make test" bug when build dir is not the source dir. + - Rsync is now licensed under the GPLv3 or later. - - Added a couple extra diffs in the "patches" dir, removed the ones - that got applied, and rebuilt the rest. + - When running the tests, we now put our per-test temp dirs into a sub- + directory named testtmp (which is created, if missing). This allows + someone to symlink the testtmp directory to another filesystem (which is + useful if the build dir's filesystem does not support ACLs and xattrs, + and another file system does). + - Rsync now has a way of handling protocol-version changes during the + development of a new protocol version. This exchange of sub-version + info does not interfere with the {MIN,MAX}_PROTOCOL_VERSION checking + in older versions (since we'd quickly exceed the MAX_PROTOCOL_VERSION + if we incremented the main PROTOCOL_VERSION value for every minor + change during development).
