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 now sends the negation option when sending the filter rules. + - Fixed a problem with the --out-format (aka --log-format) option: 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. + + - Improved --hard-link so that more corner cases are handled correctly + when combined with options such as --link-dest and/or --ignore-existing. + ENHANCEMENTS: - - You may specify --max-delete=0 to a 3.0.0 client as long as the - receiving side is at least version 3.0.0. This means that you - can pull from an older rsync with this option, but pushing to an - older rsync will generate an error. *Be careful to never specify - a 0 value to older rsync client, or it will be silently ignored.* + - A new incremental-recursion algorithm is now used when rsync is talking + to another 3.0.0 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. + + - 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. + + - 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. (If you need + to have backward compatibility with old, patched versions, the new + acls.diff patch that will add that.) + + - 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, the new + xattrs.diff patch that will add that.) + + - 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 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 man page 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 --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 any files that it wants to delete without deleting anything. If + you're not sure what version the client is, you can use the less-obvious + --max-delete=-1, as old and new versions will both 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). + + - A lot more --no-OPTION override options are now supported. 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. @@ -32,11 +119,25 @@ Changes since 2.6.9: - Added missing prototypes for compatibility functions from the lib dir. - - Figure out if the iconv() function has a const arg to avoid a compiler - warning. + - 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. - Improved the use of "const" on pointers. + - Improved J.W.'s pool_alloc routines to add a way of freeing older + sections of a pool's memory. + DEVELOPER RELATED: - - ... + - Rsync is now licensed under the GPLv3 or later. + + - Rsync now has a way of handling protocol-version changes during the + development of a new protocol version.
