(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. - - - Improved the handling of the --bwlimit option so that it's less - bursty, more accurate, and works properly over a larger range of - values. + NOTABLE CHANGES IN BEHAVIOR: - INTERNAL: + - Added the 'c'-flag to the itemizing of non-regular files so that the + itemized output doesn't get hidden if there were no attribute changes, + and also so that the itemizing of a --copy-links run will distinguish + between copying an identical non-regular file and the creation of a + revised version with a new value (e.g. a changed symlink referent, a + new device number, etc.). - - Some cleanup in the exclude code has saved some per-exclude memory - and made the code easier to maintain. + BUG FIXES: - - Use rsyserr() in the various places that were still calling - rprintf() with strerror() as an arg. + - Fixed a crash bug when a single-use rsync daemon (via remote shell) was + run without specifying a --config=FILE option. - BUILD CHANGES: + - Fixed a crash when backing up a directory that has a default ACL. - - Added a "gen" target to rebuild most of the various generated - files, including configure, config.h.in, the man pages, and - proto.h. + - Fixed a bug in the handling of xattr values that could cause rsync to + not think that a file's extended attributes are up-to-date. - - The timestamp of the proto.h file is unaltered by "make proto" - if the contents don't change. + - Fixed the working of --fake-super with --link-dest and --xattrs. - DEVELOPER RELATED: + - Fixed a hang when combining --dry-run with --remove-source-files. - - The scripts in the testsuite dir were cleaned up a bit. + - Fixed a bug with --iconv's handling of files that cannot be converted: + a failed name can no longer cause a transfer failure. - -NEWS for rsync 2.6.2 (30 Apr 2004) -Protocol: 28 (unchanged) -Changes since 2.6.1: + - Fixed the building of the rounding.h file on systems that need custom + CPPFLAGS to be used. Also improved the error reporting if the building + of rounding.h fails. - BUG FIXES: + - Fixed the use of the --protect-args (-s) option when talking to a daemon. - - 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. + - Fixed the --ignore-existing option's protection of files on the receiver + that are non-regular files on the sender (e.g. if a symlink or a dir on + the sender is trying to replace a file on the receiver). The reverse + protection (protecting a dir/symlink/device from being replaced by a + file) was already working. - - Rsync now checks the return value of the close() function to - better report disk-full problems on an NFS file system. + - Fixed an assert failure if --hard-links is combined with an option that + can skip a file in a set of hard-linked files (i.e. --ignore-existing, + --append, etc.), without skipping all the files in the set. - - 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.) + - Avoid setting the modify time on a directory that already has the right + modify time set. This avoids tweaking the dir's ctime. - - An obscure uninitialized-variable bug was fixed in the uid/gid - code. (This bug probably had no ill effects.) + - Improved the daemon-exclude handling to do a better job of applying the + exclude rules to path entries. It also sends the user an error just as + if the files were actually missing (instead of silently ignoring the + user's args), and avoids sending the user the filter-action messages + for these non-user-initiated rules. - BUILD CHANGES: + - Fixed some glitches with the dry-run code's missing-directory + handling, including a problem when combined with --fuzzy. - - 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 some glitches with the skipped-directory handling. - - Fixed a compile problem on systems that don't define - AI_NUMERICHOST. + - Fixed the 'T'-flag itemizing of symlinks when --time isn't preserved. - - Fixed a compile problem in the popt source for compilers that - don't support __attribute__. + - Fixed a glitch in the itemizing of permissions with the -E option. - DEVELOPER RELATED: + - The --append option's restricting of transfers to those that add data no + longer prevents the updating of non-content changes to otherwise up-to- + date files (i.e. those with the same content but differing permissions, + ownership, xattrs, etc.). - - Improved the testsuite's "merge" test to work on OSF1. + - Don't allow --fake-super to be specified with -XX (double --xattrs) + because the options conflict. If a daemon has "fake super" enabled, + it automatically downgrades a -XX request to -X. - - Two new diffs were added to the patches dir. + - Fixed a couple bugs in the parsing of daemon-config excludes that could + make a floating exclude rule get treated as matching an absolute path. - -NEWS for rsync 2.6.1 (26 Apr 2004) -Protocol: 28 (changed) -Changes since 2.6.0: + - A daemon doesn't try to auto-refuse the "iconv" option if iconv-support + wasn't compiled in to the daemon (avoiding a warning in the logs). - SECURITY FIXES: + - Fixed the inclusion of per-dir merge files from implied dirs. - - 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 the support/rrsync script to work with the latest options that + rsync sends (including its flag-specifying use of -e to the server). ENHANCEMENTS: - - Lower memory use, more optimal transfer of data over the socket, - and lower CPU usage (see the INTERNAL section for details). + - Added the --old-dirs (--old-d) option to make it easier for a user to + ask for file-listings with older rsync versions (this is easier than + having to type "-r --exclude='/*/*'" manually). - - The RSYNC_PROXY environment variable can now contain a - "USER:PASS@" prefix before the "HOST:PORT" information. - (Bardur Arantsson) + - When getting an error while asking an older rsync daemon for a file + listing, rsync will try to notice if the error is a rejection of the + --dirs (-d) option and let the user know how to work around the issue. - - 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 a few more --no-OPTION overrides. - - Documentation changes now attempt to describe some often mis- - understood features more clearly. + - Improved the documentation of the --append option. - BUG FIXES: - - - 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) - - - 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. + - Improved the documentation of the filter/exclude/include daemon + parameters. 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). + - Fixed a couple minor bugs in the included popt library (ones which I + sent to the official popt project for inclusion in the 1.14 release). - - Less memory is used when --checksum is specified. + - Fixed a stat() call that should have been do_stat() so that the proper + normal/64-bit stat() function gets called. (Was in an area that should + not have caused problems, though.) - - Less memory is used in the file list (a per-file savings). + - Changed the file-glob code to do a directory scan without using the + "glob" and "glob.h". This lets us do the globbing with less memory + churn, and also avoid adding daemon-excluded items to the returned + args. - - 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.) - - BUILD CHANGES: - - - The configure script now accepts --with-rsyncd-conf=PATH to - override the default value of the /etc/rsyncd.conf file. + DEVELOPER RELATED: - - Fixed configure bug when running "./configure --disable-ipv6". + - The configure script tries to get the user's compiler to not warn about + unused function parameters if the build is not including one or more of + the ACL/xattrs/iconv features. - - Fixed compilation problem on Tru64 Unix (having to do with - sockaddr.sa_len and sockaddr.sin_len). + - The configure script now has better checks for figuring out if the + included popt code should be used or not. - DEVELOPER RELATED: + - Fixed two testsuite glitches: avoid a failure if someone's "cd" command + outputs the current directory when cd-ing to a relative path, and made + the itemized test query how rsync was built to determine if it should + expect hard-linked symlinks or not. - - Fixed "make test" bug when build dir is not the source dir. + - Updated the testsuite to verify that various bug fixes remain fixed. - - Added a couple extra diffs in the "patches" dir, removed the ones - that got applied, and rebuilt the rest. + - The RPM spec file was updated to have: (1) comments for how to use the + rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file. + - Updated the build scripts to work with a revised FTP directory + structure.
