+NEWS for rsync 2.6.7 (UNRELEASED)
+Protocol: 29 (unchanged)
+Changes since 2.6.6:
- ENHANCEMENTS:
-
- * Lower memory use and more optimal transfer of data over
- the socket (see the INTERNAL section for details).
-
- * The RSYNC_PROXY environment variable can now contain a
- "USER:PASS@" prefix before the "HOST:PORT" information.
- (Bardur Arantsson)
-
- * The --progress output now mentions how far along in the
- transfer we are, including both a count of files transferred
- and a percentage of the total file-count that we've processed.
- It also shows better current-rate-of-transfer and remaining-
- transfer-time values.
-
- * The configure script now accepts --with-rsyncd-conf=PATH
- to override the default value of the /etc/rsyncd.conf file.
+ BUG FIXES:
- * Added a couple extra diffs in the "patches" dir, removed the
- ones that got applied, and rebuilt the rest.
+ - Fixed a really old bug that caused --checksum (-c) to checksum all the
+ files encountered during the delete scan (ouch).
- BUG FIXES:
+ - Made hard-links work with symlinks and devices again.
- * When -x (--one-file-system) is combined with -L (--copy-links)
- or --copy-unsafe-links, no symlinked files are skipped, even
- if the referent file is on a different filesystem.
+ - If a device-file/special-file changes permissions, rsync now updates the
+ permissions without recreating the file.
- * The --link-dest code now works properly for a non-root user
- when (1) the UIDs of the source and destination differ and -o
- was specified, or (2) when the group of the source can't be
- used on the destination and -g was specified.
+ - If the user specifies a remote-host for both the source and destination,
+ we now output a syntax error rather than trying to open the destination
+ hostspec as a filename.
- * Fixed a bug in the handling of -H (hard-links) that might
- cause the expanded PATH/NAME value of the current item to
- get overwritten (due to an expanded-name caching bug).
-
- * We now reset the "new data has been sent" flag at the start
- of each file we send. This makes sure that an interrupted
- transfer with the --partial option set doesn't keep a shorter
- temp file than the current basis file when no new data has been
- transfered over the wire for that file.
+ - When --inplace creates a new destination file, rsync now creates it with
+ permissions 0600 instead of 0000 -- this makes restarting possible when
+ the transfer gets interrupted in the middle of sending a new file.
- * Fixed a byte-order problem in --batch-mode on big-endian
- machines. (Jay Fenlason)
+ - Reject the combination of --inplace and --sparse since the sparse-output
+ algorithm doesn't work when overwriting existing data.
- * Fixed configure bug when running "./configure --disable-ipv6".
+ - Fixed the directory name in the error that is output when pop_dir()
+ fails.
- * Fixed "make test" bug when build dir is not the source dir.
+ - Really fixed the parsing of a "!" entry in .cvsignore files this time.
- * When using --cvs-exclude, the exclude items we get from a
- directory's .cvsignore file once again only affect that one
- directory (and not all following directories too). The
- items are also now properly word-split and parsed without
- any +/- prefix munging.
+ - If the generator gets a stat() error on a file, output it (this used to
+ require at least -vv for the error to be seen).
- * When specifying the USER@HOST: prefix for a file, the USER
- part can now contain an '@', if needed (i.e. the last '@'
- is used to find the HOST, not the first).
+ - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
+ the exit status properly and generate a better error.
- * Fixed some bugs in the handling of group IDs for non-root
- users: (1) It properly handles a group that the sender didn't
- have a name for (it would previously skip changing the group
- on any files in that group). (2) If --numeric-ids is used,
- rsync no longer attempts to set groups that the user doesn't
- have the permission to set.
+ - Fixed some glitches in the double-verbose output when using --copy-dest,
+ --link-dest, or --compare-dest.
- * Fixed the "refuse options" setting in the rsyncd.conf file.
+ ENHANCEMENTS:
- * Improved the -x (--one-file-system) flag's handling of any
- mount-point directories we encounter. It is both more optimal
- (in that it no longer does a useless scan of the contents of
- the mount-point dirs) and also fixes a bug where a remapped
- mount of the original filesystem could get discovered in a
- subdir we should be ignoring.
+ - 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 discards a double-slash at the start of a filename
- when trying to open the file. It also no longer constructs names
- that start with a double slash (unless the user supplied them).
+ - Added the --min-size=SIZE option to exclude small files from the
+ transfer.
- * Fixed compilation problem on Tru64 Unix (having to do with
- sockaddr.sa_len and sockaddr.sin_len).
+ - Added the --compress-level option to allow you to set how aggressive
+ rsync's compression should be (this option implies --compress).
- * Fixed a compatibility problem interacting with older rsync
- versions that might send us an empty suffix without telling us
- about the backup-dir.
+ - 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).
- * The "hosts allow" option for a daemon-over-remote-shell
- process now has improved support for IPv6 addresses and a fix
- for systems that have a length field in their socket structs.
+ - The options --human-readable (-h) and --si change the output of the
+ --stats and the end-of-run summary to be easier to read.
- * Fixed the ability to request an empty backup suffix when
- sending files to an rsync daemon.
+ - If lutimes() and/or lchmod() are around, use them to allow the
+ preservation of attributes on symlinks.
- INTERNAL:
+ - The --link-dest option now affects symlinks and devices (when
+ possible).
- * Most of the I/O is now buffered, which results in a pretty
- large speedup when running under MS Windows. (Craig Barratt)
+ - Improved the output of hard-linked and copied files when using
+ --link-dest, --copy-dest, or --compare-dest.
- * Optimizations to the name-handling/comparing code have made
- some significant reductions in user-CPU time for large file
- sets.
+ - 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.)
- * Some variable-type cleanup that makes the code more consistent.
+ - 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
+ should start. For example, if you specify a source path of
+ rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only
+ replicate the "baz/dir" part of the source path (note: a trailing
+ dot dir is unaffected unless it also has a trailing slash).
- * Reduced memory requirements of hard link preservation.
- (J.W. Schultz)
+ - 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.
- * Implemented a new algorithm for hard-link handling that speeds
- up the code significantly. (J.W. Schultz and Wayne Davison)
+ - Added the --chmod=MODE option that allows the destination permissions
+ to be changed from the source permissions. E.g. --chmod=g+w,o-rwx
- * The --hard-link option now uses the first existing file in the
- group of linked files as the basis for the transfer. This
- prevents the sub-optimal transfer of a file's data when a new
- hardlink is added on the sending side and it sorts alphabetically
- earlier in the list than the files that are already present on the
- receiving side.
+ - Allow the --temp-dir option to be specified when starting a daemon,
+ which sets the default temporary directory for incoming files.
- * Dropped support for protocol versions less than 20
- (2.3.0 released 15 Mar 1999) and activated warnings for
- protocols less than 25 (2.5.0 released 23 Aug 2001)
- (Wayne Davison and J.W. Schultz, severally)
+ - If --delete is combined with --dirs without --recursive, rsync will
+ now delete in any directory whose content is being synchronized.
- * More optimal data transmission for --hard-links (protocol 28).
+ - The file-count stats that are output by --progress were improved to
+ better indicate what the numbers mean. For instance, the output:
+ "(xfer#5, to-check=8383/9999)" indicates that this was transferred
+ file #5, and we still need to check 8383 files out of 9999 total.
- * More optimal data transmission for --checksum (protocol 28).
+ - Some minor documentation improvements.
- * Less memory is used when --checksum is specified.
+ - Updated some diffs in the patches dir.
- * Less memory is used in the file list (a per-file savings).
+ INTERNAL:
- * The generator is now better about not modifying the file list
- during the transfer in order to avoid a copy-on-write memory
- bifurcation (on systems where fork() uses shared memory).
- Previously, rsync's shared memory would slowly become unshared,
- resulting in real memory usage nearly doubling on the receiving
- side by the end of the transfer. Now, as long as permissions
- are being preserved, the shared memory should remain that way
- for the entire transfer.
+ - Some buffer sizes were expanded a bit, particularly on systems where
+ MAXPATHLEN is overly small (e.g. cygwin).
- * Changed hardlink info and file_struct + strings to use
- allocation pools. This reduces memory use for large file-
- sets and permits freeing memory to the OS. (J.W. Schultz)
+ - If io_printf() tries to format more data than fits in the buffer, exit
+ with an error instead of transmitting a truncated buffer.
- * The 2 pipes used between the receiver and generator processes
- (which are forked on the same machine) were reduced to 1 pipe
- and the protocol improved so that (1) it is now impossible to
- have the "redo" pipe fill up and hang rsync, and (2) trailing
- messages from the receiver don't get lost on their way through
- the generator over to the sender (the latter mainly affected
- hard-link messages and verbose --stats output).
+ - If a va_copy macro is defined, lib/snprintf.c will use it when defining
+ the VA_COPY macro.
- * The reading & writing of the file-list in batch-mode is now
- handled by the same code that sends & receives the list over
- the wire. This makes it much easier to maintain.
+ - Reduced the amount of stack memory needed for each level of directory
+ recursion by nearly MAXPATHLEN bytes.
- * Improved the internal uid/gid code to be more portable and
- a little more optimized.
+ DEVELOPER RELATED:
- * The device numbers sent when using --devices are now sent as
- separate major/minor values with 32-bit accuracy (protocol 28).
- Previously, the copied devices were sent as a single 32-bit
- number. This will make inter-operation of 64-bit binaries more
- compatible with their 32-bit brethren. Note that optimizations
- in the binary protocol often sends the device data using fewer
- bytes than before, even though more precision is now available.
+ - 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.
- * Some cleanup of the exclude/include structures and its code
- made things clearer, simpler, and more efficient.
