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. +NEWS for rsync 3.1.0 (UNRELEASED) +Protocol: 30 (unchanged) +Changes since 3.0.4: 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. - - - 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. - - - 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. - - - A negated filter rule (with a '!' modifier) no longer loses the negation - when sending the filter rules to the remote rsync. - - - 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 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. - - - 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. - - - Make sure that directory permissions of a newly-created destination - directory are handled right when --perms is left off. - - - The itemized output of a newly-created destination directory is now - output as a creation event, not a change event. - - - Improved --hard-link so that more corner cases are handled correctly - when combined with options such as --link-dest and/or --ignore-existing. - - - The --append option no longer updates a file that has the same size. - - - Fixed a bug when combining --backup and --backup-dir with --inplace: - any missing backup directories are now created. - - - Fixed a bug when using --backup and --inplace with --whole-file or - --read-batch: backup files are actually created now. - - - 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. - - - The daemon pidfile is checked and created sooner in the startup sequence. + - Changed the way --progress overwrites its prior output in order to make + it nearly impossible for the progress to get overwritten by an error. ENHANCEMENTS: - - 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. - - - 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. - - - If a daemon module's "path" value is not an absolute pathname, the code - now makes it absolute internally (making it work properly). - - - 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. - - - 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 (*?[). - - - Improved the dashes and double-quotes in the nroff manpage output. - - - We now support a lot more --no-OPTION override options. - - INTERNAL: - - - 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. - - - Rsync now supports the transfer of 64-bit timestamps (time_t values). - - - Fixed a build problem with older (2.x) versions of gcc. - - - Added some isType() functions that make dealing with signed characters - easier without forcing variables via casts. - - - Changed strcat/strcpy/sprintf function calls to use safer versions. - - - Upgraded the included popt version to 1.10.2 and improved its use of - string-handling functions. - - - Added missing prototypes for compatibility functions from the lib dir. - - - Configure determines if iconv() has a const arg, allowing us to avoid a - compiler warning. - - - Made the sending of some numbers more efficient for protocol 30. - - - Make sure that a daemon process doesn't mind if the client was weird and - omitted the --server option. + - Added the --remote-option=OPT (-M OPT) command-line option that is useful + for things like sending a remote --log-file=FILE or --fake-super option. - - Improved the use of "const" on pointers. + - Added the --info=FLAGS and --debug=FLAGS options to allow finer-grained + control over what is output. Added an extra type of --progress output + using --info=progress2. - - Improved J.W.'s pool_alloc routines to add a way of freeing older - sections of a pool's memory. + - Added the "%C" escape to the log-output handling, which will output the + MD5 checksum of any transferred file, or all files if --checksum was + specified (when protocol 30 or above is in effect). DEVELOPER RELATED: - - Rsync is now licensed under the GPLv3 or later. + - Added more conditional debug output. - - 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). + - Really big numbers are now output using our own big-num routine rather + than casting them to a double and using a %.0f conversion. - - 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). + - The pool_alloc library has received some minor improvements in alignment + handling.
