NEWS for rsync 3.2.0 (UNRELEASED)
|
|
Protocol: 31 (unchanged)
|
|
Changes since 3.1.3:
|
|
|
|
BUG FIXES:
|
|
|
|
- Avoid a potential out-of-bounds read in daemon mode if argc can be made
|
|
to become 0.
|
|
|
|
- Fix the default list of skip-compress files for non-daemon transfers.
|
|
|
|
- Fix xattr filter rules losing an 'x' attribute in a non-local transfer.
|
|
|
|
- Avoid an error when a check for a potential fuzzy file happens to
|
|
reference a directory.
|
|
|
|
- Make the atomic-rsync helper script have a more consistent error-exit.
|
|
|
|
- Make sure that a signal handler calls _exit() instead of exit().
|
|
|
|
- Various zlib fixes, including security fixes for CVE-2016-9843,
|
|
CVE-2016-9842, CVE-2016-9841, and CVE-2016-9840.
|
|
|
|
- Fixed an issue with --remove-source-files not removing a source symlink
|
|
when combined with --copy-links.
|
|
|
|
- Fixed a bug where the daemon would fail to write early fatal error
|
|
messages to the client, such as refused or unknown command-line options.
|
|
|
|
- Fixed the block-size validation logic when dealing with older protocols.
|
|
|
|
- Some rrsync fixes and enhancements to handle the latest options.
|
|
|
|
- Fixed a crash in the --iconv code.
|
|
|
|
- Fixed a bug in the writing of the batch.sh file (w/--write-batch) when
|
|
the source & destination args were not last on the command-line.
|
|
|
|
ENHANCEMENTS:
|
|
|
|
- Various checksum enhancements, including the optional use of openssl's
|
|
MD4 & MD5 checksum algorithms, some x86_64 optimizations for the rolling
|
|
checksum, some x86_64 optimizations for the (non-openssl) MD5 checksum,
|
|
the addition of xxhash checksum support, and a negotiation heuristic that
|
|
ensures that it is easier to add new checksum algorithms in the future.
|
|
Currently the x86_64 optimizations require the use of the --enable-simd
|
|
flag to configure, but they will probably be enabled by default in the
|
|
near future. The environment variable RSYNC_CHECKSUM_LIST can be used
|
|
to customize the preference order of the negotiation.
|
|
|
|
- Various compression enhancements, including a negotiation heuristic that
|
|
tries to pick the best compression option supported by both sides. The
|
|
environment variable RSYNC_COMPRESS_LIST can be used to customize the
|
|
preference order of the heuristic (which will be more useful when new
|
|
compression options are added).
|
|
|
|
- Added the --atimes option based on the long-standing patch (just with
|
|
some fixes that the patch has been needing).
|
|
|
|
- Added --open-noatime option to open files using O_NOATIME.
|
|
|
|
- Added the --write-devices option based on the long-standing patch.
|
|
|
|
- Added openssl support to the rsync-ssl script via its renamed helper
|
|
script, rsync-ssl-rsh. Both bash scripts are now installed by default
|
|
(removing the install-ssl-client make target). Rsync was also enhanced
|
|
to set the RSYNC_PORT environment variable when running a daemon-over-rsh
|
|
script. Its value is the user-specified port number (set via --port or an
|
|
rsync:// URL) or 0 if the user didn't override the port.
|
|
|
|
- Added negated matching to the daemon's "refuse options" setting by using
|
|
match strings that start with a "!" (such as "!compress*").
|
|
|
|
- Added status output in response to a signal (via both SIGINFO & SIGVTALRM).
|
|
|
|
- Added a --copy-as=USER option to give some extra security to root-run
|
|
rsync commands into/from untrusted directories (such as backups and
|
|
restores).
|
|
|
|
- When resuming the transfer of a file in the --partial-dir, rsync will now
|
|
update that partial file in-place instead of creating yet another tmp
|
|
file copy. This requires both sender & receiver to be at least v3.2.0.
|
|
|
|
- Added support for RSYNC_SHELL & RSYNC_NO_XFER_EXEC environment variables
|
|
that affect the pre-xfer exec and post-xfer exec rsync daemon options.
|
|
|
|
- Fixed a problem with the --link-dest|--copy-dest code when --xattrs was
|
|
specified along with multiple alternate-destination directories (it could
|
|
possibly choose a bad file match while trying to find a better xattr
|
|
match).
|
|
|
|
- Various manpage improvements.
|
|
|
|
DEVELOPER RELATED:
|
|
|
|
- Silenced some annoying warnings about major()|minor() due to the autoconf
|
|
include-file check not being smart enough.
|
|
|
|
- Improved some configure checks to work better with strict C99 compilers.
|
|
|
|
- The --debug=FOO options are no longer auto-forwarded to the server side,
|
|
allowing more control over what is output & the ability to request debug
|
|
data from divergent rsync versions.
|
|
|
|
- Some perl scripts were recoded into awk and python3.
|
|
|
|
- Some defines in byteorder.h were changed into static inline functions
|
|
that will help to ensure that the args don't get evaluated multiple times
|
|
on "careful alignment" hosts.
|
|
|
|
- Some code typos were fixed (as pointed out by a Fossies run).
