Prior versions used to output too many creation events for + matching items. - - An OS that has a binary mode for its files (such as cygwin0 needed - setmode(fd, O_BINARY) called on the temp-file we opened with - mkstemp(). (Fix picked up from the cygwin package.) + - 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 potential hang when verbosity is high, the client side is - the sender, and the file-list is large. + - A negated filter rule now sends the negation option when sending the + filter rules. - - We now check if the OS doesn't support using mknod() for creating - FIFOs and sockets, and compile-in using mkfifo() and socket() when - necessary. + - Fixed a problem with the --out-format (aka --log-format) option: it + would output superfluous directory information for a non-daemon rsync. - - Fixed an off-by-one error in the handling of --max-delete=N. + - 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. - - One place in the code wasn't checking if fork() failed. + - 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. - - The "ignore nonreadable" daemon parameter no longer affects symlinks - that are being copied, even if they point nowhere. - - - If the OS does not have lchown() and its chown() tries to set the - referent of a symlink (as it should), we no longer try to set the - user and group of a symlink. + - Make sure that directory permissions of a newly-created destination + directory are handled right when --perms is left off. ENHANCEMENTS: - - Rsync now supports popt's option aliases, which means that you can - use /etc/popt and/or ~/.popt to create your own option aliases. + - 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. + + - 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 sure to never specify a 0 value to an older rsync client, + or it will be silently ignored.* + + - 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. - - Added the --copy-dest option, which works like --link-dest except - that it includes copies of identical files. + - Upgraded the included popt version to 1.10.2 and improved its use of + string-handling functions. - - Added support for specifying multiple --compare-dest, --copy-dest, or - --link-dest options, but only of a single type. (Promoted from the - patches dir and enhanced.) + - Added missing prototypes for compatibility functions from the lib dir. - - Added the --max-size option. (Promoted from the patches dir.) + - Configure determines if iconv() has a const arg, allowing us to avoid a + compiler warning. - - The daemon-mode options were separated from the normal rsync options - so that they can't be mixed together. This makes it impossible to - start a daemon that had improper default option values that could - cause problems (such as a hang or an abort) when a client connects. + - Made the sending of some numbers more efficient for protocol 30. - - The --bwlimit option may now be used in combination with --daemon - to specify a default value for the daemon side and also a value - that cannot be exceeded by a user-specified --bwlimit option. + - Make sure that a daemon process doesn't mind if the client was weird and + omitted the --server option. - - Added the "port" parameter to the rsyncd.conf file. (Promoted from - the patches dir.) + - Improved the use of "const" on pointers. - - In _exit_cleanup(): when we are exiting with a partially-received - file, we now flush any data in the write-cache before closing the - partial file. + - Improved J.W.'s pool_alloc routines to add a way of freeing older + sections of a pool's memory. - BUILD CHANGES: + DEVELOPER RELATED: - - Handle an operating system that use mkdev() in place of makedev(). + - 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 (which would be the case if every minor change made + to the protocol in CVS incremented the main PROTOCOL_VERSION value).
