Protocol: 29 (unchanged)
Changes since 2.6.6:
+ OUTPUT CHANGES:
+
+ - The letter 'D' in the itemized output was being used for both devices
+ (character or block) as well as other special files (such as fifos and
+ named sockets). This has changed to separate non-device special files
+ under the 'S' designation (e.g. "cS+++++++ path/fifo"). See also the
+ "--specials" option, below.
+
+ - The way rsync escapes unreadable characters has changed. First, rsync
+ now has support for recognizing valid multibyte character sequences in
+ your current locale, allowing it to escape fewer characters than before
+ for a locale such as UTF-8. Second, it now uses an escape idiom of
+ "\#123", which is the literal string "\#" followed by exactly 3 octal
+ digits. Rsync no longer doubles a backslash character in a filename
+ (e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only
+ escapes a backslash that is followed by a hash-sign and 3 digits (0-9)
+ (e.g. it will output "foo\#134#789" when copying "foo\#789"). See also
+ the --8-bit-output (-8) option, mentioned below.
+
+ Script writers: the local rsync is the one that outputs escaped names,
+ so if you need to support unescaping of filenames for older rsyncs, I'd
+ suggest that you parse the output of "rsync --version" and only use the
+ old unescaping rules for 2.6.5 and 2.6.6.
+
BUG FIXES:
- Fixed a really old bug that caused --checksum (-c) to checksum all the
files encountered during the delete scan (ouch).
+ - Fixed a potential hang in a remote generator: when the receiver gets a
+ read-error on the socket, it now signals the generator about this so that
+ the generator does not try to send any of the terminating error messages
+ to the client (avoiding a potential hang in some setups).
+
- Made hard-links work with symlinks and devices again.
+ - If the sender gets an early EOF reading a source file, we propagate this
+ error to the receiver so that it can discard the file and try requesting
+ it again (which is the existing behavior for other kinds of read errors).
+
- If a device-file/special-file changes permissions, rsync now updates the
permissions without recreating the file.
the exit status properly and generate a better error.
- Fixed some glitches in the double-verbose output when using --copy-dest,
- --link-dest, or --compare-dest.
+ --link-dest, or --compare-dest. Also improved how the verbose output
+ handles hard-links (within the transfer) that had an up-to-date alternate
+ "dest" file, and copied files (via --copy-dest).
- Fixed the matching of the dont-compress items (e.g. *.gz) against files
that have a path component containing a slash.
reject a ".." dir if it would be sent as a relative dir.
- If a non-directory is in the way of a directory and rsync is run with
- --dry-run and --delete, rsync no longer complains about not being
- able to opendir() the not-yet present directory.
+ --dry-run and --delete, rsync no longer complains about not being able
+ to opendir() the not-yet present directory.
- ENHANCEMENTS:
+ - When --list-only is used and a non-existent local destination dir was
+ also specified as a destination, rsync no longer generates a warning
+ about being unable to create the missing directory.
+
+ - Fixed some problems with --relative --no-implied-dirs when the
+ destination directory did not yet exist: we can now create a symlink or
+ device when it is the first thing in the missing dir, and --fuzzy no
+ longer complains about being unable to open the missing dir.
+
+ - Fixed a bug where the --copy-links option would not affect implied
+ directories without --copy-unsafe-links (see --relative).
+
+ - Got rid of the need for --force to be used in some circumstances with
+ --delete-after (making it consistent with --delete-before/-during).
+
+ - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this
+ when a file is too large (rsync handles the write error).
- - Added the --specials option to tell rsync to copy special files (and does
- not require root). The --devices option now affects just character and
- block devices (which now matches the documentation). The -D option still
- requests both --devices and --specials, and -a still infers -D.
+ - Fixed a bug in the debug output (-vvvvv) that could mention the wrong
+ checksum for the current file offset.
- - Added the --append option that makes rsync append data onto files
- that are longer on the source than the destination (this includes new
- files).
+ - Rsync no longer allows a single directory to be copied over a non-
+ directory destination arg.
+

+ are longer on the source than the destination (this includes new files).
- Added the --min-size=SIZE option to exclude small files from the
transfer.
- Added the --compress-level option to allow you to set how aggressive
rsync's compression should be (this option implies --compress).
- - Enhanced the parsing of the SIZE value for --min-size and --max-size
- to allow easy entry of multiples of 1000 (instead of just multiples
- of 1024) and off-by-one values too (e.g. --max-size=8mb-1).

+ and off-by-one values too (e.g. --max-size=8mb-1).
+
+ - Added the --8-bit-output (-8) option, which tells rsync to avoid escaping
+ high-bit characters that it thinks are unreadable in the current locale.
- - The options --human-readable (-h) and --si change the output of the
- --stats and the end-of-run summary to be easier to read.
+ - The new option --human-readable (-h) changes the output of --progress,
+ --stats, and the end-of-run summary to be easier to read. If repeated,
+ the units become powers of 1024 instead of powers of 1000. (The old
+ meaning of -h, as a shorthand for --help, still works as long as you
+ just use it on its own, as in "rsync -h".)
- If lutimes() and/or lchmod() are around, use them to allow the
preservation of attributes on symlinks.
- - The --link-dest option now affects symlinks and devices (when
- possible).

- - Improved the output of hard-linked and copied files when using
- --link-dest, --copy-dest, or --compare-dest.
-
- - Added two config items to the rsyncd.conf parsing: "pre-xfer exec"
- and "post-xfer exec". These allow a command to be specified on a
- per-module basis that will be run before and/or after a daemon-mode
- transfer. (See the manpage for a list of the environment variables
- that are set with information about the transfer.)

- When using the --relative option, you can now insert a dot dir in
the source path to indicate where the replication of the source dirs
replicate the "baz/dir" part of the source path (note: a trailing
dot dir is unaffected unless it also has a trailing slash).
- - Added some new --no-FOO options that make it easier to override
- unwanted implied or default options. For example, "-a --no-o" (aka
- "--archive --no-owner") can be used to turn off the preservation of
- file ownership that is implied by -a.

+ be changed from the source permissions. E.g. --chmod=g+w,o-rwx
- - Added the --chmod=MODE option that allows the destination permissions
- to be changed from the source permissions. E.g. --chmod=g+w,o-rwx
+ - Added the "incoming chmod" and "outgoing chmod" daemon options that allow
+ a module to specify what permissions changes should be applied to all
+ files copied to and from the daemon.
- - Allow the --temp-dir option to be specified when starting a daemon,
- which sets the default temporary directory for incoming files.

- - If --delete is combined with --dirs without --recursive, rsync will
- now delete in any directory whose content is being synchronized.

- - If --backup is combined with --delete without --backup-dir (and
- without --delete-excluded), we add a "protect" filter-rule to ensure
- that files with the backup suffix are not deleted.

- The file-count stats that are output by --progress were improved to
better indicate what the numbers mean. For instance, the output:
to be transferred, and we still need to check 8383 more files out of
a total of 9999.
- - The include/exclude code now allows a dir/*** directive (with 3
- trailing stars) to match both the dir itself as well as all the
- content below the dir (dir/** would not match the dir).
+ - The include/exclude code now allows a dir/*** directive (with 3 trailing

+
+ - Added the --prune-empty-dirs (-m) option that makes the receiving rsync
+ discard empty chains of directories from the file-list. This makes it
+ easier to selectively copy files from a source hierarchy and end up with
+ just the directories needed to hold the resulting files.
- If the --itemize-changes (-i) option is repeated, rsync now includes
- unchanged files in the itemized output (similar to -vv, but without
- all the other verbose messages that can get in the way). Of course,
- the client must be version 2.6.7 for this to work, but the remote
- rsync only needs to be 2.6.7 if you're pushing files.

+ client must be version 2.6.7 for this to work, but the remote rsync only
+ needs to be 2.6.7 if you're pushing files.
+
+ - Added the --specials option to tell rsync to copy non-device special
+ files (which rsync now attempts even as a normal user). The --devices
+ option now requests the copying of just devices (character and block).
+ The -D option still requests both (e.g. --devices and --specials), -a
+ still implies -D, and non-root users still get a silent downgrade that
+ omits device copying.
- - Added the --super option to make the receiver always attempt super-
- user activities. This is useful for systems that allow things such
- as devices to be created or ownership to be set without being UID 0,
- and is also useful for someone who wants to ensure that errors will
- be output if the receiving rsync isn't being run as root.

- - Some minor documentation improvements.
+ - Added the --sockopts option for those few who want to customize the TCP
+ options used to contact a daemon rsync.
- - Updated some diffs in the patches dir.
+ - Added a way for the --temp-dir option to be combined with a partial-dir
+ setting that lets rsync avoid non-atomic updates (for those times when
+ --temp-dir is not being used because space is tight).
+
+ - A new support script, files-to-excludes, will transform a list of files
+ into a set of include/exclude directives that will copy those files.
+
+ - A new option, --executability (-E) can be used to preserve just the
+ execute bit on files, for those times when using the --perms option is
+ not desired.
+
+ - The daemon now logs each connection and also each module-list request
+ that it receives.
+
+ - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
+ (permission bits, e.g. "rwxr-xrwt").
+
+ - The --dry-run option no longer forces the enabling of --verbose.
+
+ - The --remove-sent-files option now does a better job of incrementally
+ removing the sent files on the sending side (older versions tended to
+ clump up all the removals at the end).
+
+ - A daemon now supersedes its minimal SIGCHLD handler with the standard
+ PID-remembering version after forking. This ensures that the generator
+ can get the child-exit status from the receiver.
+
+ - Use of the --bwlimit option no longer interferes with the remote rsync
+ sending error messages about invalid/refused options.
+
+ - Rsync no longer returns a usage error when used with one local source arg
+ and no destination: this now implies the --list-only option, just like
+ the comparable situation with a remote source arg.
+
+ - Added the --copy-dirlinks option, a more limited version of --copy-links.
+
+ - Various documentation improvements, including: a better synopsis, some
+ improved examples, a better discussion of the presence and absence of
+ --perms (including how it interacts with the new --executability and
+ --chmod options), an extended discussion of --temp-dir, an improved
+ discussion of --partial-dir, a better description of rsync's pattern
+ matching characters, an improved --no-implied-dirs section, and the
+ documenting of what the --stats option outputs.
+
+ - Various new and updated diffs in the patches dir, including: acls.diff,
+ xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
INTERNAL:
+ - We now use sigaction() and sigprocmask() if possible, and fall back on
+ signal() if not. Using sigprocmask() ensures that rsync enables all the
+ signals that it needs, just in case it was started in a masked state.
+
- Some buffer sizes were expanded a bit, particularly on systems where
MAXPATHLEN is overly small (e.g. cygwin).
- Reduced the amount of stack memory needed for each level of directory
recursion by nearly MAXPATHLEN bytes.
- - The wildmatch function was extended to allow an array of strings to
- be supplied as the string to match. This allows the exclude code to
- do less string copying.

- Got rid of the safe_fname() function (and all the myriad calls) and
- replaced it with a new function in the log.c code that filters all
- the output going to the terminal.

- Unified the f_name() and the f_name_to() functions.
+ - Improved the hash-table code the sender uses to handle checksums to make
+ it use slightly less memory and run just a little faster.
+
DEVELOPER RELATED:
+ - The diffs in the patches dir now require "patch -p1 <DIFF" instead of
+ the previous -p0. Also, the version included in the release tar now
+ affect generated files (e.g. configure, rsync.1, proto.h, etc.), so
+ it is no longer necessary to run autoconf and/or yodl unless you're
+ applying a patch that was checked out from CVS.
+
- Several diffs in the patches dir now use the proper --enable-FOO
configure option instead of --with-FOO to turn on the inclusion of
the newly patched feature.
+ - There is a new script, "prepare-source" than can be used to update the
+ various generated files (proto.h, configure, etc.) even before configure
+ has created the Makefile (this is mainly useful when patching the source
+ with a patch that doesn't affect generated files).
+
+ - The testsuite now sets HOME so that it won't be affected by a file such
+ as ~/.popt.
