1 # NEWS for rsync 3.2.0 (UNRELEASED)
3 Protocol: 31 (unchanged)
5 ## Changes since 3.1.3:
9 - Avoid a potential out-of-bounds read in daemon mode if argc can be made to
12 - Fix the default list of skip-compress files for non-daemon transfers.
14 - Fix xattr filter rules losing an 'x' attribute in a non-local transfer.
16 - Avoid an error when a check for a potential fuzzy file happens to reference
19 - Make the atomic-rsync helper script have a more consistent error-exit.
21 - Make sure that a signal handler calls `_exit()` instead of exit().
23 - Various zlib fixes, including security fixes for CVE-2016-9843,
24 CVE-2016-9842, CVE-2016-9841, and CVE-2016-9840.
26 - Fixed an issue with `--remove-source-files` not removing a source symlink
27 when combined with `--copy-links`.
29 - Fixed a bug where the daemon would fail to write early fatal error messages
30 to the client, such as refused or unknown command-line options.
32 - Fixed the block-size validation logic when dealing with older protocols.
34 - Some rrsync fixes and enhancements to handle the latest options.
36 - Fixed a crash in the `--iconv` code.
38 - Fixed a bug in the writing of the batch.sh file (w/--write-batch) when the
39 source & destination args were not last on the command-line.
43 - Various checksum enhancements, including the optional use of openssl's MD4 &
44 MD5 checksum algorithms, some x86-64 optimizations for the rolling checksum,
45 some x86-64 optimizations for the (non-openssl) MD5 checksum, the addition
46 of xxhash checksum support, and a negotiation heuristic that ensures that it
47 is easier to add new checksum algorithms in the future. Currently the
48 x86-64 optimizations require the use of the `--enable-simd` flag to
49 configure, but they will probably be enabled by default in the near future.
50 The environment variable `RSYNC_CHECKSUM_LIST` can be used to customize the
51 preference order of the negotiation.
53 - Various compression enhancements, including a negotiation heuristic that
54 tries to pick the best compression option supported by both sides. The
55 environment variable `RSYNC_COMPRESS_LIST` can be used to customize the
56 preference order of the heuristic (which will be more useful when new
57 compression options are added).
59 - Added the `--atimes` option based on the long-standing patch (just with some
60 fixes that the patch has been needing).
62 - Added `--open-noatime` option to open files using `O_NOATIME`.
64 - Added the `--write-devices` option based on the long-standing patch.
66 - Added openssl support to the rsync-ssl script via its renamed helper script,
67 rsync-ssl-rsh. Both bash scripts are now installed by default (removing the
68 install-ssl-client make target). Rsync was also enhanced to set the
69 `RSYNC_PORT` environment variable when running a daemon-over-rsh script. Its
70 value is the user-specified port number (set via `--port` or an rsync://
71 URL) or 0 if the user didn't override the port.
73 - Added negated matching to the daemon's `refuse options` setting by using
74 match strings that start with a `!` (such as `!compress*`).
76 - Added status output in response to a signal (via both SIGINFO & SIGVTALRM).
78 - Added a `--copy-as=USER` option to give some extra security to root-run
79 rsync commands into/from untrusted directories (such as backups and
82 - When resuming the transfer of a file in the `--partial-dir`, rsync will now
83 update that partial file in-place instead of creating yet another tmp file
84 copy. This requires both sender & receiver to be at least v3.2.0.
86 - Added support for `RSYNC_SHELL` & `RSYNC_NO_XFER_EXEC` environment variables
87 that affect the pre-xfer exec and post-xfer exec rsync daemon options.
89 - Fixed a problem with the `--link-dest`|`--copy-dest` code when `--xattrs`
90 was specified along with multiple alternate-destination directories (it
91 could possibly choose a bad file match while trying to find a better xattr
94 - Various manpage improvements.
96 ### DEVELOPER RELATED:
98 - Silenced some annoying warnings about major()|minor() due to the autoconf
99 include-file check not being smart enough.
101 - Improved some configure checks to work better with strict C99 compilers.
103 - The `--debug=FOO` options are no longer auto-forwarded to the server side,
104 allowing more control over what is output & the ability to request debug
105 data from divergent rsync versions.
107 - Some perl scripts were recoded into awk and python3.
109 - Some defines in byteorder.h were changed into static inline functions that
110 will help to ensure that the args don't get evaluated multiple times on
111 `careful alignment` hosts.
113 - Some code typos were fixed (as pointed out by a Fossies run).
