+NEWS for rsync 3.1.0 (UNRELEASED)
+Protocol: 31 (changed)
+Changes since 3.0.4:
+
+ OUTPUT CHANGES:
+
+ - Output numbers in 3-digit groups by default (e.g. 1,234,567). See the
+ --human-readable option for a way to turn it off. See also the daemon's
+ "log format" parameter and related command-line options (including
+ --out-format) for a modifier that can be used to request digit-grouping
+ or human-readable output in log escapes. (Note that log output is
+ unchanged by default.)
+
+ - The --list-only option is now affected by the --human-readable setting.
+ It will display digit groupings by default, and unit suffixes if higher
+ levels of readability are requested. Also, the column width for the size
+ output has increased from 11 to 14 characters when human readability is
+ enabled. Use --no-h to get the old-style output and column size.
+
+ - The output of the --progress option has changed: the string "xfer" was
+ shortened to "xfr", and the string "to-check" was shortened to "to-chk",
+ both designed to make room for the (by default) wider display of file
+ size numbers without making the total line-length longer. Also, when
+ incremental recursion is enabled, the string "ir-chk" will be used
+ instead of "to-chk" up until the incremental-recursion scan is done,
+ letting you know that the value to check and the total value will still
+ be increasing as new files are found.
+
+ - Enhanced the --stats output: 1) to mention how many files were created
+ (protocol >= 28), 2) to mention how many files were deleted (a new line
+ for protocol 31, but only output when --delete is in effect), and 3) to
+ follow the file-count, created-count, and deleted-count with a subcount
+ list that shows the counts by type. The wording of the transferred count
+ has also changed so that it is clearer that it is only a count of regular
+ files.
- ENHANCEMENTS:
+ BUG FIXES:
- * Lower memory use and more optimal transfer of data over
- the socket (see the INTERNAL section for details).
+ - Changed the way --progress overwrites its prior output in order to make
+ it nearly impossible for the progress to get overwritten by an error.
- * The RSYNC_PROXY environment variable can now contain a
- "USER:PASS@" prefix before the "HOST:PORT" information.
- (Bardur Arantsson)
+ - Fixed some rare bugs in --iconv processing that might cause a multibyte
+ character to get translated incorrectly.
- * The --progress output now mentions how far along in the
- transfer we are, including both a count of files transferred
- and a percentage of the total file-count that we've processed.
- It also shows better current-rate-of-transfer and remaining-
- transfer-time values.
+ - Improved the propagation of abnormal-exit error messages. This should
+ help the client side to receive errors from the server when it is exiting
+ abnormally, and should also avoid dying with an "connection unexpectedly
+ closed" exit when the closed connection is really expected.
- * The configure script now accepts --with-rsyncd-conf=PATH
- to override the default value of the /etc/rsyncd.conf file.
+ ENHANCEMENTS:
- * Added a couple extra diffs in the "patches" dir, removed the
- ones that got applied, and rebuilt the rest.
+ - 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.
- BUG FIXES:
+ - 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.
- * When -x (--one-file-system) is combined with -L (--copy-links)
- or --copy-unsafe-links, no symlinked files are skipped, even
- if the referant file is on a different filesystem.
+ - The --msgs2stderr option can help with debugging rsync by allowing the
+ debug messages to get output to stderr rather than travel via the socket
+ protocol.
- * The --link-dest code now works properly for a non-root user
- when (1) the UIDs of the source and destination differ and -o
- was specified, or (2) when the group of the source can't be
- used on the destination and -g was specified.
+ - Added the --delete-missing-args and --ignore-missing-args options to
+ either delete or ignore user-specified files on the receiver that are
+ missing on the sender (normally the absence of user-specified files
+ generates an error).
- * Fixed a bug in the handling of -H (hard-links) that might
- cause the expanded PATH/NAME value of the current item to
- get overwritten (due to an expanded-name caching bug).
-
- * We now reset the "new data has been sent" flag at the start
- of each file we send. This makes sure that an interrupted
- transfer with the --partial option set doesn't keep a shorter
- temp file than the current basis file when no new data has been
- transfered over the wire for that file.
+ - Added a "T" (terabyte) category to the --human-readable size suffixes.
- * Fixed a byte-order problem in --batch-mode on big-endian
- machines. (Jay Fenlason)
+ - Added the --usermap/--groupmap/--chown options for manipulating file
+ ownership during the copy.
- * Fixed configure bug when running "./configure --disable-ipv6".
+ - 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).
- * Fixed "make test" bug when build dir is not the source dir.
+ - Added the "reverse lookup" parameter to the rsync daemon config file to
+ allow reverse-DNS lookups to be disabled.
- * When using --cvs-exclude, the exclude items we get from a
- directory's .cvsignore file once again only affect that one
- directory (and not all following directories too).
+ - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can
+ be disabled via "forward lookup" parameter (defaults to enabled).
- * When specifying the USER@HOST: prefix for a file, the USER
- part can now contain an '@', if needed (i.e. the last '@'
- is used to find the HOST, not the first).
+ - Added a way for more than one group to be specified in the daemon's
+ config file, including a way to specify that you want all of the
+ specified user's groups without having to name them. Also changed the
+ daemon to complain about an inability to set explicitly-specified uid/gid
+ values, even when not run by a super-user.
- * Fixed some bugs in the handling of group IDs for non-root
- users: (1) It properly handles a group that the sender didn't
- have a name for (it would previously skip changing the group
- on any files in that group). (2) If --numeric-ids is used,
- rsync no longer attempts to set groups that the user doesn't
- have the permission to set.
+ - Added per-user authorization options and group-authorization support to
+ the daemon's "auth users" parameter.
- * Fixed the "refuse options" setting in the rsyncd.conf file.
+ - Added a way to reference environment variables in a daemon's config file
+ (using %VAR% references).
- * Improved the -x (--one-file-system) flag's handling of any
- mount-point directories we encounter. It is both more optimal
- (in that it no longer does a useless scan of the contents of
- the mount-point dirs) and also fixes a bug where a remaped
- mount of the original filesystem could get discovered on a
- disk we should be ignoring.
+ - When replacing a non-dir with a symlink/hard-link/device/special-file,
+ the update should now be done in an atomic manner.
- * Rsync no longer discards a double-slash at the start of a filename
- when trying to open the file. It also no longer constructs names
- that start with a double slash (unless the user supplied them).
+ - Fixed a free of the wrong pointer in uncache_tmp_xattrs() (which only
+ sometimes affects an --xattr transfer when --backup is used).
- * Fixed compilation problem on Tru64 Unix (having to do with
- sockaddr.sa_len and sockaddr.sin_len).
+ - When backing up a file, try to hard-link the file into place so that the
+ upcoming replacement of the destination file will be atomic.
- * Fixed a compatibility problem interacting with older rsync
- versions that might send us an empty suffix without telling us
- about the backup-dir.
+ - Added the ability to synchronize nano-second modified times.
- * The "hosts allow" option for a daemon-over-remote-shell
- process now has improved support for IPv6 addresses and a fix
- for systems that have a length field in their socket structs.
+ - Added a few more default suffixes for the "dont compress" settings.
- INTERNAL:
-
- * Most of the I/O is now buffered, which results in a pretty
- large speedup when running under MS Windows. (Craig Barratt)
+ - Added the checking of the RSYNC_PROTECT_ARGS environment variable to allow
+ the default for the --protect-args command-line option to be overridden.
- * Optimizations to the name-handling/comparing code have made
- some significant reductions in user-CPU time for large file
- sets.
+ - Added some Solaris xattr code.
- * Some variable-type cleanup that makes the code more consistent.
+ EXTRAS:
- * Reduced memory requirements of hard link preservation.
- (J.W. Schultz)
+ - Added an "instant-rsyncd" script to the support directory, which makes
+ it easy to configure a simple rsync daemon in the current directory.
- * Implemented a new algorithm for hard-link handling that speeds
- up the code significantly. (J.W. Schultz and Wayne Davison)
+ - Added the "mapfrom" and "mapto" scripts to the support directory, which
+ makes it easier to do user/group mapping in a local transfer based on
+ passwd/group files from another machine.
- * The --hard-link option now uses the first existing file in the
- group of linked files as the basis for the transfer. This
- prevents the sub-optimal transfer of a file's data when a new
- hardlink is added on the sending side and it sorts alphabetically
- earlier in the list than the files that are already present on the
- receiving side.
+ INTERNAL:
- * Dropped support for protocol versions less than 20
- (2.3.0 released 15 Mar 1999) and activated warnings for
- protocols less than 25 (2.5.0 released 23 Aug 2001)
- (Wayne Davison and J.W. Schultz, severally)
+ - The I/O code was rewritten to be simpler and do bigger buffered reads
+ over the socket. The I/O between the receiver and the generator was
+ changed to be standard multiplexed-I/O (like that over the socket).
- * More optimal data transmission for --hard-links (protocol 28).
+ - The sender tries to use any dead time while the generator is looking for
+ files to transfer in order to do sender-side directory scanning in a more
+ parallel manner.
- * More optimal data transmission for --checksum (protocol 28).
+ - A daemon can now inform a client about a daemon-configured timeout value
+ so that the client can assist in the keep-alive activity (protocol 31).
- * Less memory is used when --checksum is specified.
+ - The filter code received some refactoring to make it more extendable, to
+ read better, and do better sanity checking.
- * Less memory is used in the file list (a per-file savings).
+ - Really big numbers are now output using our own big-num routine rather
+ than casting them to a double and using a %.0f conversion.
- * The generator is now better about not modifying the file list
- during the transfer in order to avoid a copy-on-write memory
- bifurcation (on systems where fork() uses shared memory).
- Previously, rsync's shared memory would slowly become unshared,
- resulting in real memory usage nearly doubling on the receiving
- side by the end of the transfer. Now, as long as permissions
- are being preserved, the shared memory should remain that way
- for the entire transfer.
+ - The pool_alloc library has received some minor improvements in alignment
+ handling.
- * Changed hardlink info and file_struct + strings to use
- allocation pools. This reduces memory use for large
- filesets and permits freeing memory to the OS. (J.W. Schultz)
+ - Added init_stat_x() function to avoid duplication of acl/xattr init code.
- * The 2 pipes used between the receiver and generator processes
- (which are forked on the same machine) were reduced to 1 pipe
- and the protocol improved so that (1) it is now impossible to
- have the "redo" pipe fill up and hang rsync, and (2) trailing
- messages from the receiver don't get lost on their way through
- the generator over to the sender (the latter mainly affected
- hard-link messages and verbose --stats output).
+ DEVELOPER RELATED:
- * The reading & writing of the file-list in batch-mode is now
- handled by the same code that sends & receives the list over
- the wire. This makes it much easier to maintain.
+ - Added more conditional debug output.
- * Improved the internal uid/gid code to be more portable and
- a little more optimized.
+ - Changed configure.in to configure.ac.
