-rsync changes since last release
+NEWS for rsync 3.0.0 (UNRELEASED)
+Protocol: 30 (changed)
+Changes since 2.6.9:
- ENHANCEMENTS:
-
- * The --delete-after option now implies --delete. (Wayne Davison)
-
- * The --suffix option can now be used with --backup-dir. (Michael
- Zimmerman)
-
- * Combining "::" syntax with the -rsh/-e option now uses the
- specified remote-shell as a transport to talk to a (newly-spawned)
- server-daemon. This allows someone to use daemon features, such
- as modules, over a secure protocol, such as ssh. (JD Paul)
-
- * The rsync:// syntax for daemon connections is now accepted in the
- destination field.
-
- * If the file name given to --include-from or --exclude-from is "-",
- rsync will read from standard input. (J.W. Schultz)
-
- * New option --link-dest which is like --compare-dest except that
- unchanged files are hard-linked in to the destination directory.
- (J.W. Schultz)
-
- * Don't report an error if an excluded file disappears during an
- rsync run. (Eugene Chupriyanov and Bo Kersey)
-
- * Added .svn to --cvs-exclude list to support subversion. (Jon
- Middleton)
+ BUG FIXES:
- * Properly support IPv6 addresses in the rsyncd.conf "hosts allow"
- and "hosts deny" fields. (Hideaki Yoshifuji)
+ - Fixed the output of -ii when combined with one of the --*-dest options:
+ it now itemizes all the items, not just the changed ones.
- * Changed exclude file handling to permit DOS or MAC style line
- terminations. (J.W. Schultz)
+ - 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.
- * Ignore errors from chmod when -p/-a/--preserve-perms is not set.
- (Dave Dykstra)
+ - 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.
- BUG FIXES:
-
- * Fix "forward name lookup failed" errors on AIX 4.3.3. (John
- L. Allen, Martin Pool)
+ - A negated filter rule now sends the negation option when sending the
+ filter rules.
- * Generate each file's rolling-checksum data as we send it, not
- in a separate (memory-eating) pass before hand. This prevents
- timeout errors on really large files. (Stefan Nehlsen)
+ - Fixed a problem with the --out-format (aka --log-format) option: it
+ would output superfluous directory information for a non-daemon rsync.
- * Fix compilation on Tru64. (Albert Chin, Zoong Pham)
+ - 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.
- * Better handling of some client-server errors. (Martin Pool)
+ - 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 a crash that would occur when sending a list of files that
- contains a duplicate name (if it sorts to the end of the file
- list) and using --delete. (Wayne Davison)
+ - Make sure that directory permissions of a newly-created destination
+ directory are handled right when --perms is left off.
- * Fixed the file-name duplicate-removal code when dealing with multiple
- dups in a row. (Wayne Davison)
+ ENHANCEMENTS:
- * Fixed a bug that caused rsync to lose the exit status of its child
- processes and sometimes return an exit code of 0 instead of showing
- an error. (David R. Staples, Dave Dykstra)
+ - 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).
- * Fixed bug in --copy-unsafe-links that caused it to be completely
- broken. (Dave Dykstra)
+ INTERNAL:
- * Prevent infinite recursion in cleanup code under certain circumstances.
- (Sviatoslav Sviridov and Marc Espie)
+ - Rsync now supports the transfer of 64-bit timestamps (time_t values).
- * Fixed a bug that prevented rsync from creating intervening directories
- when --relative-paths/-R is set. (Craig Barratt)
+ - Fixed a build problem with older (2.x) versions of gcc.
- * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara)
+ - Added some isType() functions that make dealing with signed characters
+ easier without forcing variables via casts.
- * Prevent some hangs at the end of a run on Cygwin. (Anthony Heading)
+ - Upgraded the included popt version to 1.10.2 and improved its use of
+ string-handling functions.
- INTERNAL:
+ - Added missing prototypes for compatibility functions from the lib dir.
- * Many code cleanups and improved internal documentation. (Martin
- Pool, Nelson Beebe)
+ - Configure determines if iconv() has a const arg, allowing us to avoid a
+ compiler warning.
- * Portability fixes. (Dave Dykstra and Wayne Davison)
+ - Made the sending of some numbers more efficient for protocol 30.
- * More test cases. (Martin Pool)
+ - Make sure that a daemon process doesn't mind if the client was weird and
+ omitted the --server option.
- * Some test-case fixes. (Brian Poole, Wayne Davison)
+ - Improved the use of "const" on pointers.
- * Updated included popt to the latest vendor drop, version 1.6.4.
- (Jos Backus)
+ DEVELOPER RELATED:
- * Updated config.guess and config.sub to latest versions; this
- means rsync should build on more platforms. (Paul Green)
+ - 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).
