+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.) When some level of human-readable output is
+ enabled, the column width for the file size in the --list-only output
+ is increased.
+
+ - 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 (new 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 broken down by type.
BUG FIXES:
- - An rsync daemon that is receiving files with "use chroot = no" no longer
- sanitizes the symlink target strings. This means that each symlink's
- value will now be accepted (and thus returned) with its symlink info
- intact. Also, in order to keep things safe, all arg paths and any
- dereferenced symlinks (e.g. via --copy-links or --keep-dirlinks) are
- manually verified to ensure that no symlinks try to escape past the top
- of the module's path. These changes make a non-chroot daemon behave the
- same way as a chroot daemon with regard to symlinks, and also avoids a
- potential problem where a pre-existing symlink could have escaped the
- module's hierarchy.
-
- - Fixed a overzealous sanitizing bug in the handling of the --*-dest
- options (--link-dest, --copy-dest, and --compare-dest): if the copy's
- destination dir is deeper than the top of the module's path, these
- options now accept a safe number of ../ (parent-dir) references (since
- these options are relative to the destination dir). The old code
- incorrectly chopped off all "../" prefixes for these options, no matter
- how deep the destination directory was in the module's hierarchy.
-
- - Fixed a bug where a deferred info/error/log message could get sent
- directly to the sender instead of being handled by rwrite() in the
- generator. This fixes an "unexpected tag 3" fatal error, and should
- also fix a potential problem where a deferred info/error message from
- the receiver might bypass the log file and get sent only to the client
- process. (These problems could only affect an rsync daemon that was
- receiving files.)
-
- - Make sure that the --link-dest option can still do its job even when -I
- or --size-only is specified.
-
- - The daemon now calls more timezone-using functions prior to doing a
- chroot. This should help some C libraries to generate proper timestamps
- from inside a chrooted daemon (and to not try to access /etc/timezone
- over and over again).
-
- - Fixed a bug in the handling of an absolute --partial-dir=ABS_PATH option:
- it now deletes an alternate basis file from the partial-dir that was used
- to successfully update a destination file.
+ - Fixed a bug in incremental recursion transfers where an I/O error might
+ not get noticed in time for the receiving side to disable deletions
+ (requires protocol 31).
+
+ - Changed the way --progress overwrites its prior output in order to make
+ it nearly impossible for the progress to get overwritten by an error.
+
+ - An absolute-path filter rule (i.e. with a '/' modifier) no longer loses
+ its modifier when sending the filter rules to the remote rsync.
+
+ - Fixed some rare bugs in --iconv processing that might cause a multibyte
+ character to get translated incorrectly.
+
+ - Improved 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:
- - Added the --log-file=FILE option that can be used to tell any rsync to
- output what it is doing to a log file. This works with a client rsync, a
- non-daemon server rsync (see the man page for instructions), and also
- allows the overriding of the rsyncd.conf setting when starting a daemon.
+ - 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.
- DEVELOPER RELATED:
+ - 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.
+
+ - 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.
+
+ - 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 "T" (terabyte) category to the --human-readable size suffixes.
+
+ - Added the --usermap/--groupmap/--chown options for manipulating file
+ ownership during the copy.
+
+ - 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 the "reverse lookup" parameter to the rsync daemon config file to
+ allow reverse-DNS lookups to be disabled.
+
+ - 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.
+
+ - Added a way to reference environment variables in a daemon's config file
+ (using %VAR% references).
- - The acls.diff and xattrs.diff patches have received a bunch of work to
- make them much closer to being acceptable in the main distribution.
+ - When replacing a non-dir with a symlink/hard-link/device/special-file,
+ the update should now be done in an atomic manner.
- - Updated config.guess and config.sub to their 2006-02-23 version.
+ - Fixed a free of the wrong pointer in uncache_tmp_xattrs() (which only
+ sometimes affects an --xattr transfer when --backup is used).
+
+ - 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.
+
+ - Added the ability to synchronize nano-second modified times.
+
+ - Added a few more default suffixes for the "dont compress" settings.
+
+ - Added some Solaris xattr code.
+
+ EXTRAS:
+
+ - Added an "instant-rsyncd" script to the support directory, which makes
+ it easy to configure a simple rsync daemon in the current directory.
+
+ - 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:
+
+ - 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.
+
+ - The pool_alloc library has received some minor improvements in alignment
+ handling.
+
+ - Added init_stat_x() function to avoid duplication of acl/xattr init code.
+
+ DEVELOPER RELATED:
- - Updated various files to include the latest FSF address and to have
- consistent opening comments.
+ - Added more conditional debug output.
