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. BUG FIXES: - - Fixed a bug in the exclude code where an anchored exclude without any - wildcards fails to match an absolute source arg, but only when --relative - is in effect. + - 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. - - Improved the I/O code for the generator to fix a potential hang when the - receiver gets an EOF on the socket but the generator's select() call - never indicates that the socket is writable for it to be notified about - the EOF. (This can happen when using stunnel). + - 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. ENHANCEMENTS: - - The support/rsyncstats script has an improved line-parsing regex that is - easier to read and also allows it to parse syslog-generated lines. + - 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). - - A new script, support/file-attr-restore, can be used to restore the - attributes of a fileset (the permissions, ownership, and group info) - taken from the cached output of a "find ARG... -ls" command. + - 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. + + - 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: - - A new patch was added: log-file.diff. This contains an early version of - a future option, --log-file=FILE, that will allow any rsync to log its - actions to a file (something that only a daemon supports at present). + - 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 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).
