If you're one of those rare people who relied upon having an - implied dir be duplicated as a symlink, you should specify the transfer - of the symlink and the transfer of the referent directory as separate - args. (See also --keep-dirlinks and --no-implied-dirs.) - - - Requesting a remote file list without specifying -r (--recursive) now - sends the -d (--dirs) option to the remote rsync rather than sending -r - along with an extra exclude of /*/*. If the remote rsync does not - understand the -d option (i.e. it is 2.6.3 or older), you will need to - either turn off -d (--no-d), or specify -r --exclude='/*/*' manually. +NEWS for rsync 3.0.1 (UNRELEASED) +Protocol: 30 (unchanged) +Changes since 3.0.0: BUG FIXES: - - Fixed the output of -ii when combined with one of the --*-dest options: - it now itemizes all the items, not just the changed ones. + - Fixed a crash bug when a single-use rsync daemon (via remote shell) was + run without specifying a --config=FILE option. - - 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. + - Fixed a crash when backing up a directory that has a default ACL. - - 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. + - 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. - - A negated filter rule (with a '!' modifier) no longer loses the negation - when sending the filter rules to the remote rsync. + - Fixed the working of --fake-super with --link-dest and --xattrs. - - 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 hang when combining --dry-run with --remove-source-files. - - 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 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. - - 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. + - Fixed the use of the --protect-args (-s) option when talking to a daemon. - - Make sure that directory permissions of a newly-created destination - directory are handled right when --perms is left off. + - 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. - - The itemized output of a newly-created destination directory is now - output as a creation event, not a change event. + - Fixed an assert failure if --hard-links is combined with an option that + can cause a file in a set of hard-linked files to be skipped (i.e. if + --append, --ignore-existing, etc. affects one or more files in a hard- + linked set of files, but not all of them). - - Improved --hard-link so that more corner cases are handled correctly - when combined with options such as --link-dest and/or --ignore-existing. + - Avoid setting the time on a directory that already has the modify time + that we're setting. This avoids tweaking the dir's ctime. - - The --append option no longer updates a file that has the same size. + - Improved the daemon-exclude handling to do a better job of excluding + a wider range of path entries. It also sends the user an error about + "missing" files instead of silently ignoring them. - - Fixed a bug when combining --backup and --backup-dir with --inplace: - any missing backup directories are now created. + - Fixed some glitches with the dry-run code's missing-directory + handling, including a problem when combined with --fuzzy. - - Fixed a bug when using --backup and --inplace with --whole-file or - --read-batch: backup files are actually created now. + - Fixed some glitches with the skipped-directory handling. - - 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. + - Fixed the 'T'-flag itemizing of symlinks when --time isn't preserved. - - The daemon pidfile is checked and created sooner in the startup sequence. + - Fixed a glitch in the itemizing of permissions with the -E option. - - If a daemon module's "path" value is not an absolute pathname, the code - now makes it absolute internally (making it work properly). + - 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. symlink referent, device + numbers). - ENHANCEMENTS: + - 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.). - - 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. - - - Lowered memory use 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 --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 (*?[). - - - 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 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. - - - 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.) - - - 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). - - - 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). - - - 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. - - - 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). - - - Protocol 30 now uses MD5 checksums instead of MD4. - - - Changed the --append option to not checksum the existing data in the - destination file, which speeds up file appending. - - - 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. - - - Documented and extended the support for the RSYNC_CONNECT_PROG variable - that can be used to enhance the client side of a daemon connection. - - - Improved the dashes and double-quotes in the nroff manpage output. - - - We now support a lot more --no-OPTION override options. + - Don't allow --fake-super to be specified with -XX (double --xattrs) + because they conflict. If a daemon has "fake super" enabled, it + automatically downgrades a -XX request to -X. - INTERNAL: + - 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). - - 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. + - Fixed the support/rrsync script to work with the latest options that + rsync sends (including its flag-specifying use of -e to the server). - - Rsync now supports the transfer of 64-bit timestamps (time_t values). + ENHANCEMENTS: - - Fixed a build problem with older (2.x) versions of gcc. + - 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. - - Added some isType() functions that make dealing with signed characters - easier without forcing variables via casts. + - Added a few more --no-OPTION overrides. - - Changed strcat/strcpy/sprintf function calls to use safer versions. + - Improved the documentation of the --append option. - - Upgraded the included popt version to 1.10.2 and improved its use of - string-handling functions. + - Improved the documentation of the filter/exclude/include daemon + parameters. - - Added missing prototypes for compatibility functions from the lib dir. + INTERNAL: - - Configure determines if iconv() has a const arg, allowing us to avoid a - compiler warning. + - 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). - - Made the sending of some numbers more efficient for protocol 30. + - 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.) - - Make sure that a daemon process doesn't mind if the client was weird and - omitted the --server option. + - 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. - - Improved the use of "const" on pointers. + DEVELOPER RELATED: - - Improved J.W.'s pool_alloc routines to add a way of freeing older - sections of a pool's memory. + - 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. - DEVELOPER RELATED: + - The configure script now has better checks for figuring out if the + included popt should be used or not. + + - 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. - - Rsync is now licensed under the GPLv3 or later. - - - 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 causes any out-of-sync - versions to speak an older protocol rather than fail in a cryptic manner. - This addition makes it safe to deploy a pre-release version that may - interact with the public. This new exchange of sub-version info does not - interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which - does not have enough range to allow the main protocol number to be - incremented for every minor tweak in that happens during development). + - Updated the build scripts to work with a revised FTP directory + structure.
