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:
- 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.
ENHANCEMENTS:
- 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.
- 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).
- When replacing a non-dir with a symlink/hard-link/device/special-file,
the update should now be done in an atomic manner.
- 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:
- Added more conditional debug output.
