Protocol: 30 (changed)
Changes since 2.6.9:
- NOTABLE CHANGE IN BEHAVIOR:
+ NOTABLE CHANGES IN BEHAVIOR:
- - The handling of implied directories when using --relative has changed
- to send them as directories (e.g. no implied dir is ever sent as a
- symlink). This avoids unexpected behavior and should not adversely
- affect most people. If you're one of those rare people who relied
- upon having an implied dir be duplicated as a symlink, either specify
- --keep-dirlinks or --no-implied-dirs.
+ - The handling of implied directories when using --relative has changed to
+ send them as directories (e.g. no implied dir is ever sent as a symlink).
+ This avoids unexpected behavior and should not adversely affect most
+ people. If you're one of those rare individuals who relied upon having
+ an implied dir be duplicated as a symlink, you should specify the
+ transfer of the symlink and the transfer of the referent directory as
+ separate args. (See also --keep-dirlinks and --no-implied-dirs.)
+
+ - Requesting a remote file list without specifying -r (--recursive) now
+ sends the -d (--dirs) option to the remote rsync rather than sending -r
+ along with an extra exclude of /*/*. If the remote rsync does not
+ understand the -d option (i.e. it is 2.6.3 or older), you will need to
+ either turn off -d (--no-d), or specify -r --exclude='/*/*' manually.
+
+ - In --dry-run mode, the last line of the verbose summary text is output
+ with a "(DRY RUN)" suffix to help remind you that no updates were made.
BUG FIXES:
it now itemizes all the items, not just the changed ones.
- Made the output of all file types consistent when using a --*-dest
- option. Prior versions used to output too many creation events for
+ option. Prior versions would output too many creation events for
matching items.
- The code that waits for a child pid now handles being interrupted by a
signal. This fixes a problem with the pre-xfer exec function not being
able to get the exit status from the script.
- - A negated filter rule (with a '!' modifier) no longer loses the negation
- when sending the filter rules to the remote rsync.
+ - A negated filter rule (i.e. with a '!' modifier) no longer loses the

- Fixed a problem with the --out-format (aka --log-format) option %f: it
- would output superfluous directory information for a non-daemon rsync.
+ no longer outputs superfluous directory info for a non-daemon rsync.
- Fixed a problem with -vv (double --verbose) and --stats when "pushing"
files (which includes local copies). Version 2.6.9 would complete the
- Fixed a bug when using --backup and --inplace with --whole-file or
--read-batch: backup files are actually created now.
- - Starting up an extra copy of an rsync daemon does not delete the pidfile
- for the running daemon -- if the pidfile exists, the extra program will
- exit with an error.
+ - Starting up an extra copy of an rsync daemon will not clobber the pidfile
+ for the running daemon -- if the pidfile exists, the new daemon will exit
+ with an error.
- The daemon pidfile is checked and created sooner in the startup sequence.
+ - If a daemon module's "path" value is not an absolute pathname, the code
+ now makes it absolute internally (making it work properly).
+
+ - Ensure that a temporary file always has owner-write permission while we
+ are writing to it. This avoids problems with some network filesystems.
+
+ - Any errors output about password-file reading no longer cause an error at
+ the end of the run about a partial transfer.
+
ENHANCEMENTS:
- A new incremental-recursion algorithm is now used when rsync is talking
(before all the files have been found), and requires much less memory.
See the --recursive option in the manpage for some restrictions.
- - Saved memory in the non-incremental-recursion algorithm for typical
+ - Lowered memory use in the non-incremental-recursion algorithm for typical
option values (usually saving from 21-29 bytes per file).
- The default --delete algorithm is now --delete-during when talking to a
- Rsync now allows multiple remote-source args to be specified rather than
having to rely on a special space-splitting side-effect of the remote-
- shell. Additional remote args must specify the same host or have an
- empty hostname, as seen here: :file1 ::module/file2. This means that
- local use of brace expansion now works: rsync -av host:path/{f1,f2} .
+ shell. Additional remote args must specify the same host or an empty one
+ (e.g. empty: :file1 or ::module/file2). This means that local use of
+ brace expansion now works: rsync -av host:dir/{f1,f2} .
+
+ - Added the --protect-args (-s) option, that tells rsync to send most of
+ the command-line args at the start of the transfer rather than as args
+ to the remote-shell command. This protects them from space-splitting,
+ and only interprets basic wildcard special shell characters (*?[).
- Added the --delete-delay option, which is a more efficient way to delete
files at the end of the transfer without needing a separate delete pass.
- Added the --acls (-A) option to preserve Access Control Lists. This is
an improved version of the prior patch that was available, and it even
- supports OS X ACLs. (If you need to have backward compatibility with
- old, patched versions of rsync, apply the acls.diff file from the patches
- dir.)
+ supports OS X ACLs. If you need to have backward compatibility with old,
+ acl-patched versions of rsync, apply the acls.diff file from the patches
+ dir.
- Added the --xattrs (-X) option to preserver extended attributes. This is
- an improved version of the prior patch that was available. (If you need
- to have backward compatibility with old, patched versions of rsync, apply
- the xattrs.diff file from the patches dir.)
+ an improved version of the prior patch that was available, and it even
+ supports OS X xattrs (which includes their resource fork data). If you
+ need to have backward compatibility with old, xattr-patched versions of
+ rsync, apply the xattrs.diff file from the patches dir.
- Added the --fake-super option that allows a non-super user to preserve
all attributes of a file by using a special extended-attribute idiom.
+ It even supports the storing of foreign ACL data on your backup server.
There is also an analogous "fake super" option for an rsync daemon.
- Added the --iconv option, which allows rsync to convert filenames from
rebuild. If you want rsync to perform character-set conversions by
default, you can specify --enable-iconv=CONVERT_STRING with the default
value for the --iconv option that you wish to use. For example,
- --enable-iconv=. is a good choice. See the rsync manpage for an
+ "--enable-iconv=." is a good choice. See the rsync manpage for an
explanation of the --iconv option's settings.
- - Added the --skip-compress=LIST option to override of the default list of
+ - Added the --skip-compress=LIST option to override the default list of
file suffixes that will not be compressed when using --compress.
- The daemon's default for "dont compress" was extended to include:
- Protocol 30 now uses MD5 checksums instead of MD4.
- - If a daemon module's "path" value is not an absolute pathname, the code
- now makes it absolute internally (making it work properly).
-
- Changed the --append option to not checksum the existing data in the
destination file, which speeds up file appending.
- Documented and extended the support for the RSYNC_CONNECT_PROG variable
that can be used to enhance the client side of a daemon connection.
- - Added the --protect-args (-s) option, that tells rsync to send most of
- the command-line args at the start of the transfer rather than as args
- to the remote-shell command. This protects them from space-splitting,
- and only interprets basic wildcard special shell characters (*?[).
-
- Improved the dashes and double-quotes in the nroff manpage output.
- We now support a lot more --no-OPTION override options.
- Improved J.W.'s pool_alloc routines to add a way of freeing older
sections of a pool's memory.
+ - The getaddrinfo.c compatibility code in the "lib" dir was replaced with
+ some new code (derived from samba, derived from PostgreSQL) that has a
+ better license than the old code.

+ versions to speak an older protocol rather than fail in a cryptic manner.
+ This addition makes it safe to deploy a pre-release version that may
+ interact with the public. This new exchange of sub-version info does not
+ interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which
+ does not have enough range to allow the main protocol number to be
+ incremented for every minor tweak in that happens during development).
