-rsync changes since last release
+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:
+
+ - Changed the way --progress overwrites its prior output in order to make
+ it nearly impossible for the progress to get overwritten by an error.
+
+ - Fixed some rare bugs in --iconv processing that might cause a multibyte
+ character to get translated incorrectly.
+
+ - 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:
- * The --delete-after option now implies --delete. (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.
- * The --suffix option can now be used with --backup-dir. (Michael
- Zimmerman)
+ - 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.
- * 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 --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 rsync:// syntax for daemon connections is now accepted in the
- destination field.
+ - 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).
- * If the file name given to --include-from or --exclude-from is "-",
- rsync will read from standard input. (J.W. Schultz)
+ - Added a "T" (terabyte) category to the --human-readable size suffixes.
- * New option --link-dest which is like --compare-dest except that
- unchanged files are hard-linked in to the destination directory.
- (J.W. Schultz)
+ - Added the --usermap/--groupmap/--chown options for manipulating file
+ ownership during the copy.
- * Don't report an error if an excluded file disappears during an
- rsync run. (Eugene Chupriyanov and Bo Kersey)
+ - 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).
- * Added .svn to --cvs-exclude list to support subversion. (Jon
- Middleton)
+ - Added the "reverse lookup" parameter to the rsync daemon config file to
+ allow reverse-DNS lookups to be disabled.
- * Properly support IPv6 addresses in the rsyncd.conf "hosts allow"
- and "hosts deny" fields. (Hideaki Yoshifuji)
+ - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can
+ be disabled via "forward lookup" parameter (defaults to enabled).
- * Set the default value of --modify-window to 1 on Cygwin. (Lapo
- Luchini)
+ - 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.
- * Open config files in text mode when O_TEXT is defined. This helps
- on Cygwin when the config files are on a filesystem that are mounted
- in binary mode. (Ville Herva)
+ - Added per-user authorization options and group-authorization support to
+ the daemon's "auth users" parameter.
- * Ignore errors from chmod when -p/-a/--preserve-perms is not set.
- (Dave Dykstra)
+ - Added a way to reference environment variables in a daemon's config file
+ (using %VAR% references).
- BUG FIXES:
-
- * Fix "forward name lookup failed" errors on AIX 4.3.3. (John
- L. Allen, Martin Pool)
+ - When replacing a non-dir with a symlink/hard-link/device/special-file,
+ the update should now be done in an atomic manner.
- * 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 free of the wrong pointer in uncache_tmp_xattrs() (which only
+ sometimes affects an --xattr transfer when --backup is used).
- * Fix compilation on Tru64. (Albert Chin, Zoong Pham)
+ - 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.
- * Better handling of some client-server errors. (Martin Pool)
+ - Added the ability to synchronize nano-second modified times.
- * 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)
+ - Added a few more default suffixes for the "dont compress" settings.
- * Fixed the file-name duplicate-removal code when dealing with multiple
- dups in a row. (Wayne Davison)
+ - Added the checking of the RSYNC_PROTECT_ARGS environment variable to allow
+ the default for the --protect-args command-line option to be overridden.
- * 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)
+ - Added some Solaris xattr code.
- * Fixed bug in --copy-unsafe-links that caused it to be completely
- broken. (Dave Dykstra)
+ EXTRAS:
- * Prevent infinite recursion in cleanup code under certain circumstances.
- (Sviatoslav Sviridov and Marc Espie)
+ - Added an "instant-rsyncd" script to the support directory, which makes
+ it easy to configure a simple rsync daemon in the current directory.
- * Fixed a bug that prevented rsync from creating intervening directories
- when --relative-paths/-R is set. (Craig Barratt)
+ - 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.
INTERNAL:
- * Many code cleanups and improved internal documentation. (Martin
- Pool, Nelson Beebe)
+ - 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).
+
+ - 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.
+
+ - 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).
+
+ - The filter code received some refactoring to make it more extendable, to
+ read better, and do better sanity checking.
+
+ - Really big numbers are now output using our own big-num routine rather
+ than casting them to a double and using a %.0f conversion.
- * Portability fixes. (Dave Dykstra and Wayne Davison)
+ - The pool_alloc library has received some minor improvements in alignment
+ handling.
- * More test cases. (Martin Pool)
+ - Added init_stat_x() function to avoid duplication of acl/xattr init code.
- * Some test-case fixes. (Brian Poole, Wayne Davison)
+ DEVELOPER RELATED:
- * Updated included popt to the latest vendor drop, version 1.6.4.
- (Jos Backus)
+ - Added more conditional debug output.
- * Updated config.guess and config.sub to latest versions; this
- means rsync should build on more platforms. (Paul Green)
+ - Changed configure.in to configure.ac.
