+NEWS for rsync 2.6.4 (UNRELEASED)
+Protocol: 29 (changed)
+Changes since 2.6.3:
- 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're processed.
+ OUTPUT CHANGES:
- * The configure script now accepts --with-rsyncd-conf=PATH
- to override the default value of the /etc/rsyncd.conf file.
+ - 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 --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:
- * When -x (--one-file-system) is combined with -L (--copy-links)
- or --copy-unsafe-links, no symlinked files are skipped, even
- if the referant file is on a different filesystem.
-
- * The --link-dest code now works properly for a non-root user
- when the UIDs of the source and destination differ and -o was
- specified, and when the group of the source can't be used on
- the destination and -g was specified. (Wayne Davison)
-
- * 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).
- (Wayne Davison)
-
- * 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. (Wayne Davison)
-
- * Fixed a byte-order problem in --batch-mode on big-endian
- machines. (Jay Fenlason)
-
- * Fixed configure bug when running "./configure --disable-ipv6".
- (Wayne Davison)
-
- * 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).
-
- * When transferring a file that has group 0 with -g specified
- (typically via -a) and not enough privs to retain the group,
- rsync no longer complains about "chown" failing.
-
- * 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.
+ - 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).
- * Fixed the "refuse options" setting in the 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.
- * 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 both).
+ - Avoid a mkdir warning when removing a directory in the destination
+ that already exists in the --backup-dir.
- INTERNAL:
-
- * Most of the I/O is now buffered, which results in a pretty
- large speedup when running under MS Windows. (Craig Barratt)
-
- * Optimizations to the name-handling/comparing code have made
- some significant reductions in user-CPU time for large file
- sets. (Wayne Davison)
-
- * Some variable-type cleanup that makes the code more consistent.
- (Wayne Davison)
-
- * Reduced memory requirements of hard link preservation.
- (J.W. Schultz)
-
- * Implemented a new algorithm for hard-link handling that speeds
- up the code significantly. (J.W. Schultz and Wayne Davison)
-
- * 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.
+ - 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.)
- * 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)
+ - Fixed a potential hang when verbosity is high, the client side is
+ the sender, and the file-list is large.
- * More optimal data transmission for --hard-links (protocol 28).
+ - 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.
- * More optimal data transmission for --checksum (protocol 28).
+ - Fixed an off-by-one error in the handling of --max-delete=N.
- * Less memory is used when --checksum is specified.
+ - One place in the code wasn't checking if fork() failed.
- * Less memory is used in the file list (a per-file savings).
+ - The "ignore nonreadable" daemon parameter no longer affects symlinks
+ that are being copied, even if they point nowhere.
- * Changed hardlink info and file_struct + strings to use
- allocation pools. This reduces memory use for large
- filesets and permits freeing memory to the OS. (J.W. Schultz)
+ - 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.
- * 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). (Wayne Davison)
+ - 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.
- * 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.
+ - 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.
- * Optimized the -x (--one-file-system) flag's handling of any
- mount-point directories we encounter (it no longer scans the
- contents of the mount-point dirs, just to throw away the data).
+ - One call to flush_write_file() was not being checked for an error.
- * Improved the internal uid/gid code to be more portable and
- a little more optimized.
+ - The --no-relative option was not being sent from the client to a
+ server sender.

-NEWS for rsync 2.6.0 (1 Jan 2004)
-Protocol: 27 (changed)
-Changes since 2.5.7:
+ - 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).
ENHANCEMENTS:
- * "ssh" is now the default remote shell for rsync. If you want to
- change this, configure like this: "./configure --with-rsh=rsh".
-
- * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
- Note that --from0 affects the line-ending character for all the
- files read by the --*-from options. (Wayne Davison)
-
- * Length of csum2 is now per-file starting with protocol version
- 27. (J.W. Schultz)
-
- * Per-file dynamic block size is now sqrt(file length). The
- per-file checksum size is determined according to an algorithm
- provided by Donovan Baarda which reduces the probability of rsync
- algorithm corrupting data and falling back using the whole md4
- checksums. (J.W. Schultz, Donovan Baarda)
-
- * The --stats option no longer includes the (debug) malloc summary
- unless the verbose option was specified at least twice.
-
- * Added a new error/warning code for when files vanish from the
- sending side. Made vanished source files not interfere with the
- file-deletion pass when --delete-after was specified.
-
- * Various trailing-info sections are now preceded by a newline.
+ - 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.
+
+ - 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.
+
+ 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.
- BUG FIXES:
-
- * Fixed several exclude/include matching bugs when using wild-cards.
- This has a several user-visible effects, all of which make the
- matching more consistent and intuitive. This should hopefully not
- cause anyone problems since it makes the matching work more like
- what people are expecting. (Wayne Davison)
-
- - A pattern with a "**" no longer causes a "*" to match slashes.
- For example, with "/*/foo/**", "foo" must be 2 levels deep.
- [If your string has BOTH "*" and "**" wildcards, changing the
- "*" wildcards to "**" will provide the old behavior in all
- versions.]
-
- - "**/foo" now matches at the base of the transfer (like /foo
- does). [Use "/**/foo" to get the old behavior in all versions.]
-
- - A non-anchored wildcard term floats to match beyond the base of
- the transfer. E.g. "CVS/R*" matches at the end of the path,
- just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
- to get the old behavior in all versions.]
-
- - Including a "**" in the match term causes it to be matched
- against the entire path, not just the name portion, even if
- there aren't any interior slashes in the term. E.g. "foo**bar"
- would exclude "/path/foo-bar" (just like before) as well as
- "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
- old behavior in all versions.]
-
- * The exclude list specified in the daemon's config file is now
- properly applied to the pulled items no matter how deep the
- user's file-args are in the source tree. (Wayne Davison)
-
- * For protocol version >= 27, mdfour_tail() is called when the
- block size (including checksum_seed) is a multiple of 64.
- Previously it was not called, giving the wrong MD4 checksum.
- (Craig Barratt)
-
- * For protocol version >= 27, a 64 bit bit counter is used in
- mdfour.c as required by the RFC. Previously only a 32 bit bit
- counter was used, causing incorrect MD4 file checksums for
- file sizes >= 512MB - 4. (Craig Barratt)
-
- * Fixed a crash bug when interacting with older rsync versions and
- multiple files of the same name are destined for the same dir.
- (Wayne Davison)
-
- * Keep tmp names from overflowing MAXPATHLEN.
-
- * Make --link-dest honor the absence of -p, -o, and -g.
-
- * Made rsync treat a trailing slash in the destination in a more
- consistent manner.
-
- * Fixed file I/O error detection. (John Van Essen)
-
- * Fixed bogus "malformed address {hostname}" message in rsyncd log
- when checking IP address against hostnames from "hosts allow"
- and "hosts deny" parameters in config file.
-
- * Print heap statistics when verbose >= 2 instead of when >= 1.
-
- * Fixed a compression (-z) bug when syncing a mostly-matching file
- that contains already-compressed data. (Yasuoka Masahiko and
- Wayne Davison)
-
- * Fixed a bug in the --backup code that could cause deleted files
- to not get backed up.
-
- * When the backup code makes new directories, create them with mode
- 0700 instead of 0755 (since the directory permissions in the
- backup tree are not yet copied from the main tree).
-
- * Call setgroups() in a more portable manner.
-
- * Improved file-related error messages to better indicate exactly
- what pathname failed. (Wayne Davison)
-
- * Fixed some bugs in the handling of --delete and --exclude when
- using the --relative (-R) option. (Wayne Davison)
-
- * Fixed bug that prevented regular files from replacing
- special files and caused a directory in --link-dest or
- --compare-dest to block the creation of a file with the
- same path. A directory still cannot be replaced by a
- regular file unless --delete specified. (J.W. Schultz)
+ INTERNAL:
- * Detect and report when open or opendir succeed but read and
- readdir fail caused by network filesystem issues and truncated
- files. (David Norwood, Michael Brown, J.W. Schultz)
+ - Added better checking of the checksum-header values that come over
+ the socket.
- * Added a fix that should give ssh time to restore the tty settings
- if the user presses Ctrl-C at an ssh password prompt.
+ - Merged the various delete-file functions into a single function so
+ that it is easier to maintain.
- INTERNAL:
+ - Improved the type of some variables (particularly blocksize vars) for
+ consistency and proper size.
- * Eliminated vestigial support for old versions that we stopped
- supporting. (J.W. Schultz)
+ - Got rid of the uint64 type (which we didn't need).
- * Simplified some of the option-parsing code. (Wayne Davison)
+ BUILD CHANGES:
- * Some cleanup made to the exclude code, as well as some new
- defines added to enhance readability. (Wayne Davison)
+ - Handle an operating system that use mkdev() in place of makedev().
- * Changed the protocol-version code so that it can interact at a
- lower protocol level than the maximum supported by both sides.
- Added an undocumented option, --protocol=N, to force the value
- we advertise to the other side (primarily for testing purposes).
- (Wayne Davison)
+ - Improved configure to better handle cross-compiling.
