+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.
BUG FIXES:
- * The --link-dest code now works properly for a non-root user
- when the UIDs of the source and destination differ and -u was
- specified, and when the group of the source can't be used on
- the destination and -g was specified. (Wayne Davison)
-
- * 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).
- (Wayne Davison)
-
- * Keep per-file track of the sending of literal data with
- --partial so that an interrupted transfer doesn't keep a
- shorter temp file when no new data has been transfered over
- the wire.
-
- * Fixed a byte-order problem in --batch-mode on big-endian
- machines. (Jay Fenlason)
-
- INTERNAL:
-
- * Most of the I/O is now buffered, which results in a pretty
- large speedup when running under MS Windows. (Craig Barratt)
-
- * Optimizations to the name-handling/comparing code have made
- some significant reductions in user CPU time for large file
- sets. (Wayne Davison)
-
- * Some variable-type cleanup that makes the code more consistent.
- (Wayne Davison)
+ - Changed the way --progress overwrites its prior output in order to make
+ it nearly impossible for the progress to get overwritten by an error.
- * Reduced memory requirements of hard link preservation.
- (J.W. Schultz)
+ - Fixed some rare bugs in --iconv processing that might cause a multibyte
+ character to get translated incorrectly.
- * Got rid of support for protocol versions 17 and 18 (which are
- both over 6 years old).
-
- * More optimal data transmission for --hard-links (protocol 28).
-
- * More optimal data transmission for --checksum (protocol 28).
-
- * Less memory used for holding --checksum data.

-NEWS for rsync 2.6.0 (1 Jan 2004)
-Protocol: 27 (changed)
-Changes since 2.5.7:
+ - 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.
ENHANCEMENTS:
- * "ssh" is now the default remote shell for rsync. If you want to
- change this, configure like this: "./configure --with-rsh=rsh".
-
- * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
- Note that --from0 affects the line-ending character for all the
- files read by the --*-from options. (Wayne Davison)
+ - 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.
- * Length of csum2 is now per-file starting with protocol version
- 27. (J.W. Schultz)
+ - 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.
- * Per-file dynamic block size is now sqrt(file length). The
- per-file checksum size is determined according to an algorithm
- provided by Donovan Baarda which reduces the probability of rsync
- algorithm corrupting data and falling back using the whole md4
- checksums. (J.W. Schultz, Donovan Baarda)
+ - 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 --stats option no longer includes the (debug) malloc summary
- unless the verbose option was specified at least twice.
+ - 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).
- * Added a new error/warning code for when files vanish from the
- sending side. Made vanished source files not interfere with the
- file-deletion pass when --delete-after was specified.
+ - Added a "T" (terabyte) category to the --human-readable size suffixes.
- * Various trailing-info sections are now preceded by a newline.
+ - Added the --usermap/--groupmap/--chown options for manipulating file
+ ownership during the copy.
- BUG FIXES:
+ - 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 several exclude/include matching bugs when using wild-cards.
- This has a several user-visible effects, all of which make the
- matching more consistent and intuitive. This should hopefully not
- cause anyone problems since it makes the matching work more like
- what people are expecting. (Wayne Davison)
+ - Added the "reverse lookup" parameter to the rsync daemon config file to
+ allow reverse-DNS lookups to be disabled.
- - A pattern with a "**" no longer causes a "*" to match slashes.
- For example, with "/*/foo/**", "foo" must be 2 levels deep.
- [If your string has BOTH "*" and "**" wildcards, changing the
- "*" wildcards to "**" will provide the old behavior in all
- versions.]
+ - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can
+ be disabled via "forward lookup" parameter (defaults to enabled).
- - "**/foo" now matches at the base of the transfer (like /foo
- does). [Use "/**/foo" to get the old behavior in all versions.]
+ - 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.
- - A non-anchored wildcard term floats to match beyond the base of
- the transfer. E.g. "CVS/R*" matches at the end of the path,
- just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
- to get the old behavior in all versions.]
+ - Added per-user authorization options and group-authorization support to
+ the daemon's "auth users" parameter.
- - Including a "**" in the match term causes it to be matched
- against the entire path, not just the name portion, even if
- there aren't any interior slashes in the term. E.g. "foo**bar"
- would exclude "/path/foo-bar" (just like before) as well as
- "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
- old behavior in all versions.]
+ - Added a way to reference environment variables in a daemon's config file
+ (using %VAR% references).
- * The exclude list specified in the daemon's config file is now
- properly applied to the pulled items no matter how deep the
- user's file-args are in the source tree. (Wayne Davison)
+ - When replacing a non-dir with a symlink/hard-link/device/special-file,
+ the update should now be done in an atomic manner.
- * For protocol version >= 27, mdfour_tail() is called when the
- block size (including checksum_seed) is a multiple of 64.
- Previously it was not called, giving the wrong MD4 checksum.
- (Craig Barratt)
+ - Avoid re-sending xattr info for hard-linked files w/the same xattrs
+ (protocol 31).
- * For protocol version >= 27, a 64 bit bit counter is used in
- mdfour.c as required by the RFC. Previously only a 32 bit bit
- counter was used, causing incorrect MD4 file checksums for
- file sizes >= 512MB - 4. (Craig Barratt)
+ - 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 crash bug when interacting with older rsync versions and
- multiple files of the same name are destined for the same dir.
- (Wayne Davison)
+ - Added the ability to synchronize nano-second modified times.
- * Keep tmp names from overflowing MAXPATHLEN.
+ - Added a few more default suffixes for the "dont compress" settings.
- * Make --link-dest honor the absence of -p, -o, and -g.
+ - Added the checking of the RSYNC_PROTECT_ARGS environment variable to allow
+ the default for the --protect-args command-line option to be overridden.
- * Made rsync treat a trailing slash in the destination in a more
- consistent manner.
+ - Added some Solaris xattr code.
- * Fixed file I/O error detection. (John Van Essen)
+ EXTRAS:
- * Fixed bogus "malformed address {hostname}" message in rsyncd log
- when checking IP address against hostnames from "hosts allow"
- and "hosts deny" parameters in config file.
+ - Added an "instant-rsyncd" script to the support directory, which makes
+ it easy to configure a simple rsync daemon in the current directory.
- * Print heap statistics when verbose >= 2 instead of when >= 1.
+ - 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.
- * Fixed a compression (-z) bug when syncing a mostly-matching file
- that contains already-compressed data. (Yasuoka Masahiko and
- Wayne Davison)
-
- * Fixed a bug in the --backup code that could cause deleted files
- to not get backed up.
-
- * When the backup code makes new directories, create them with mode
- 0700 instead of 0755 (since the directory permissions in the
- backup tree are not yet copied from the main tree).
-
- * Call setgroups() in a more portable manner.
+ INTERNAL:
- * Improved file-related error messages to better indicate exactly
- what pathname failed. (Wayne Davison)
+ - 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).
- * Fixed some bugs in the handling of --delete and --exclude when
- using the --relative (-R) option. (Wayne Davison)
+ - 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.
- * Fixed bug that prevented regular files from replacing
- special files and caused a directory in --link-dest or
- --compare-dest to block the creation of a file with the
- same path. A directory still cannot be replaced by a
- regular file unless --delete specified. (J.W. Schultz)
+ - 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).
- * Detect and report when open or opendir succeed but read and
- readdir fail caused by network filesystem issues and truncated
- files. (David Norwood, Michael Brown, J.W. Schultz)
+ - The filter code received some refactoring to make it more extendable, to
+ read better, and do better sanity checking.
- * Added a fix that should give ssh time to restore the tty settings
- if the user presses Ctrl-C at an ssh password prompt.
+ - Really big numbers are now output using our own big-num routine rather
+ than casting them to a double and using a %.0f conversion.
- INTERNAL:
+ - The pool_alloc library has received some minor improvements in alignment
+ handling.
- * Eliminated vestigial support for old versions that we stopped
- supporting. (J.W. Schultz)
+ - Added init_stat_x() function to avoid duplication of acl/xattr init code.
- * Simplified some of the option-parsing code. (Wayne Davison)
+ DEVELOPER RELATED:
- * Some cleanup made to the exclude code, as well as some new
- defines added to enhance readability. (Wayne Davison)
+ - Added more conditional debug output.
- * Changed the protocol-version code so that it can interact at a
- lower protocol level than the maximum supported by both sides.
- Added an undocumented option, --protocol=N, to force the value
- we advertise to the other side (primarily for testing purposes).
- (Wayne Davison)
+ - Changed configure.in to configure.ac.
