+NEWS for rsync 2.6.4 (UNRELEASED)
+Protocol: 29 (changed)
+Changes since 2.6.3:
- ENHANCEMENTS:
+ OUTPUT CHANGES:
- * Lower memory use and more optimal transfer of data over
- the socket (see the INTERNAL section for details).
+ - When rsync deletes a directory and outputs a verbose message about
+ it, it now appends a trailing slash to the name instead of (only
+ sometimes) outputting a preceding "directory " string.
- * The RSYNC_PROXY environment variable can now contain a
- "USER:PASS@" prefix before the "HOST:PORT" information.
- (Bardur Arantsson)
+ - The --stats output will contain file-list time-statistics if both
+ sides are 2.6.4, or if the local side is 2.6.4 and the files are
+ being pushed (since the stats come from the sending side).
+
+ BUG FIXES:
- * 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.
+ - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3
+ was only treating it as a special token in an rsync include/exclude
+ file).
- * The configure script now accepts --with-rsyncd-conf=PATH
- to override the default value of the /etc/rsyncd.conf file.
+ - The --dry-run option (-n) now mentions changes in directories (w/-v).
+ It also now includes the normal uptodate output information for -vv.
- * Added a couple extra diffs in the "patches" dir, removed the
- ones that got applied, and rebuilt the rest.
+ - Avoid a mkdir warning when removing a directory in the destination
+ that already exists in the --backup-dir.
- BUG FIXES:
+ - An OS that has a binary mode for its files (such as cygwin0 needed
+ setmode(fd, O_BINARY) called on the temp-file we opened with
+ mkstemp(). (Fix derived from the cygwin's rsync package.)
- * 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.
-
- * 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.
-
- * 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.
-
- * Fixed a byte-order problem in --batch-mode on big-endian
- machines. (Jay Fenlason)
-
- * Fixed configure bug when running "./configure --disable-ipv6".
-
- * Fixed "make test" bug when build dir is not the source dir.
-
- * 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.
-
- * 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).
-
- * 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 the "refuse options" setting in the rsyncd.conf file.
-
- * 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.
-
- * 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).
-
- * Path-specifying options to a daemon should now work the same with
- or without chroot turned on. Previously, such a option (such as
- --link-dest) would get its absolute path munged into a relative
- one if chroot was not on, making that setting fairly useless.
- Rsync now transforms the path into one that is based on the
- module's base dir when chroot is not enabled.
-
- * Fixed compilation problem on Tru64 Unix (having to do with
- sockaddr.sa_len and sockaddr.sin_len).
-
- * Fixed a compatibility problem interacting with older rsync
- versions that might send us an empty --suffix value without
- telling us that --backup-dir was specified.
-
- * 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.
-
- * Fixed the ability to request an empty backup --suffix when
- sending files to an rsync daemon.
+ - Fixed a potential hang when verbosity is high, the client side is
+ the sender, and the file-list is large.
- INTERNAL:
+ - We now check if the OS doesn't support using mknod() for creating
+ FIFOs and sockets, and compile-in using mkfifo() and socket() when
+ necessary.
+
+ - Fixed an off-by-one error in the handling of --max-delete=N.
- * Most of the I/O is now buffered, which results in a pretty
- large speedup when running under MS Windows. (Craig Barratt)
+ - One place in the code wasn't checking if fork() failed.
- * Optimizations to the name-handling/comparing code have made
- some significant reductions in user-CPU time for large file
- sets.
+ - The "ignore nonreadable" daemon parameter no longer affects symlinks
+ that are being copied, even if they point nowhere.
- * Some variable-type cleanup that makes the code more consistent.
+ - If the OS does not have lchown() and its chown() tries to set the
+ referent of a symlink (as it should), we no longer try to set the
+ user and group of a symlink.
- * Reduced memory requirements of hard link preservation.
- (J.W. Schultz)
+ - The generator now properly runs the hard-link loop and the dir-time
+ rewriting loop after we're sure that the redo phase is complete.
- * Implemented a new algorithm for hard-link handling that speeds
- up the code significantly. (J.W. Schultz and Wayne Davison)
+ - When --backup was specified with --partial-dir=DIR (where DIR is a
+ relative path), the backup code was erroneously trying to backup a
+ file that was put into the partial-dir.
- * 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.
+ - One call to flush_write_file() was not being checked for an error.
- * 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)
+ - The --no-relative option was not being sent from the client to a
+ server sender.
- * More optimal data transmission for --hard-links (protocol 28).
+ - If an rsync daemon specified "dont compress = ..." for a file and the
+ client tried to specify --compress, the libz code was not handling a
+ compression level of 0 properly. This could cause a transfer failure
+ if the block-size for a file was large enough (i.e. rsync might have
+ exited with an error for large files).
- * More optimal data transmission for --checksum (protocol 28).
+ - If a daemon can't open the specified log file (i.e. syslog is not
+ being used), die without crashing. We also try to output an error
+ about the failure (which will only be seen if --no-detach was
+ specified).
+
+ ENHANCEMENTS:
+
+ - Rsync now supports popt's option aliases, which means that you can
+ use /etc/popt and/or ~/.popt to create your own option aliases.
+
+ - Added the --delete-during (--del) option which will delete files
+ from on the receiving side incrementally as each directory in the
+ transfer is being processed (which makes it more efficient than the
+ default, before-the-transfer behavior of --delete). Note that the
+ --del option is implemented as an internally-defined popt alias, so
+ an rsync daemon that refuses "delete" (which, for safety's sake,
+ really matches "delete*") will still refuse all delete options. The
+ default behavior is also explicitly selectable via --delete-before.
+
+ - Added the --copy-dest option, which works like --link-dest except
+ that it includes copies of identical files.
+
+ - Added support for specifying multiple --compare-dest, --copy-dest, or
+ --link-dest options, but only of a single type. (Promoted from the
+ patches dir and enhanced.)
+
+ - Added the --max-size option. (Promoted from the patches dir.)
+
+ - The daemon-mode options were separated from the normal rsync options
+ so that they can't be mixed together. This makes it impossible to
+ start a daemon that had improper default option values that could
+ cause problems (such as a hang or an abort) when a client connects.
+
+ - The --bwlimit option may now be used in combination with --daemon
+ to specify both a default value for the daemon side and a value
+ that cannot be exceeded by a user-specified --bwlimit option.
+
+ - Added the "port" parameter to the rsyncd.conf file. (Promoted from
+ the patches dir.) Also added "address".
+
+ - In _exit_cleanup(): when we are exiting with a partially-received
+ file, we now flush any data in the write-cache before closing the
+ partial file.
+
+ - The --inplace support was enhanced to work with --compare-dest,
+ --link-dest, and (the new) --copy-dest options.
+
+ - Added the --dirs (-d) option for an easier way to copy directories
+ without recursion.
+
+ - Added the --list-only option which is mainly a way for the client to
+ put the server into listing mode without needing to resort to any
+ option kluges (e.g. the age-old use of "-r --exclude="/*/*" for a
+ non-recursive listing). This option is used automatically when a
+ modern rsync speaks to a modern daemon, but may also be specified
+ manually if you want to force the use of the --list-only option over
+ a remote-shell connection.
+
+ - Added the --omit-dir-times (-O) option which will avoid updating the
+ modified time for directories when --times was specified. This
+ option will avoid an extra pass through the file-list at the end of
+ the transfer (to tweak all the directory times), which can result in
+ an appreciable speedup for a really large transfer.
+
+ - Added the --filter (-f) option and its helper option, -F. Filter
+ rules are an extension to the existing include/exclude handling
+ that also supports nested filter files as well as per-directory
+ filter files (like .cvsignore, but with full filter-rule parsing).
+ This new option was chosen in order to ensure that all existing
+ include/exclude processing remained 100% compatible with older
+ versions.
+
+ - Added the --delay-updates option that puts all updated files into
+ a temporary directory (by default ".~tmp~", but settable via the
+ --partial-dir=DIR option) until the end of the transfer. This
+ makes the updates a little more atomic for a large transfer.
+
+ - If rsync is put into the background, any output from --progress is
+ reduced.
+
+ - Documented the "max verbosity" setting for rsyncd.conf. (This
+ setting was added a couple releases ago, but left undocumented.)
+
+ SUPPORT FILES:
+
+ - Added support/atomic-rsync -- a perl script that will transfer some
+ files using rsync, and then move the updated files into place all at
+ once at the end of the transfer. Only works when pulling, and uses
+ --link-dest and a parallel hierarchy of files to effect its update.
+
+ - Added support/mnt-excl that takes the /proc/mounts file and
+ translates it into a set of excludes that will exclude all mount
+ points (even mapped mounts to the same disk). The excludes are made
+ relative to the specified source dir and properly anchored.
+
+ - Added support/savetransfer.c -- a C program that can make a copy of
+ all the data that flows over the wire. This lets you test for data
+ corruption (by saving the data on both the sending side and the
+ receiving side) or provides a way to help debug a protocol error.
+
+ - Added support/rrsync -- my version of Joe Smith's restricted rsync
+ perl script. This helps to ensure that only certain rsync commands
+ can be run by an ssh invocation.
+
+ - Improved the option descriptions in the --help text.
+
+ INTERNAL:
- * Less memory is used when --checksum is specified.
+ - Added better checking of the checksum-header values that come over
+ the socket.
- * Less memory is used in the file list (a per-file savings).
+ - Merged the various delete-file functions into a single function so
+ that it is easier to maintain.
- * 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.
+ - Improved the type of some variables (particularly blocksize vars) for
+ consistency and proper size.
- * 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)
+ - Got rid of the uint64 type (which we didn't need).
- * 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).
+ - Use a slightly more compatible set of core #include directives.
- * 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.
+ - Defined int32 in a way that ensures that the build dies if we can't
+ find a variable with at least 32 bits.
- * Improved the internal uid/gid code to be more portable and
- a little more optimized.
+ BUILD CHANGES:
- * 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.
+ - Handle an operating system that use mkdev() in place of makedev().
- * Some cleanup of the exclude/include structures and its code
- made things clearer, simpler, and more efficient.
+ - Improved configure to better handle cross-compiling.
