OUTPUT CHANGES:
- - The itemized output now uses 'S' for a special file instead of
- clumping them together with the 'D' for devices. The number of
- characters is also different (to remove an unused field).
+ - 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
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.
--dry-run and --delete, rsync no longer complains about not being able
to opendir() the not-yet present directory.
+ - 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 (see --relative) without --copy-unsafe-links.
+
- Got rid of the need for --force to be used in some circumstances with
--delete-after (making it consistent with --delete-before/-during).
- ENHANCEMENTS:
+ - 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 implies -D.
+ ENHANCEMENTS:
- Added the --append option that makes rsync append data onto files that
are longer on the source than the destination (this includes new files).
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).
- - The options --human-readable (-h) and --si change the output of the
- --stats and the end-of-run summary to be easier to read.
+ - 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 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
+ the man page 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
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 --super option to make the receiver always attempt super- user
+ - 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
execute bit on files, for those times when using the --perms option is
not desired.
- - Some minor documentation improvements.
+ - 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.
- - Updated some diffs in the patches dir.
+ - 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 to handle the request. 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.
+
+ - The sender's hash table for checksum information was improved to make it
+ more efficient when updating really large files (starting from around
+ 2.5GB, but most visibly for much larger files). This prevents the hash
+ table from getting overloaded, which saves CPU time (and real time) at
+ the expense of a little extra memory (and it actually saves memory for
+ normal sized files).
+
+ - 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).
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.
- - The testsuite now sets HOME so that it won't be affecting by a file
- such as ~/.popt.
+ - 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.
