+NEWS for rsync 2.6.4 (UNRELEASED)
+Protocol: 29 (changed)
+Changes since 2.6.3:
+
+ OUTPUT CHANGES:
+
+ - 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).
+ (Requires protocol 29 for a pull.)
+
+ - The "%o" (operation) log-format escape now has a third value (besides
+ "send" and "recv"): "del." (with trailing dot to make it 4 chars).
+ This changes the way deletions are logged in the daemon's log file.
+
+ - When the --log-format option is combined with --verbose, rsync now
+ avoids outputting the name of the file twice in most circumstances.
+ As long as the --log-format item does not refer to any post-transfer
+ items (such as %b or %c), the --log-format message is output prior to
+ the transfer with --verbose being the equivalent of a --log-format of
+ '%n%L' (which outputs the name and any symlink info). If the log
+ output must occur after the transfer to be complete, the only time
+ the name is also output prior to the transfer is when --progress was
+ specified (so that the name will precede the progress stats, and the
+ full --log-format output will come after).
+
BUG FIXES:
- - Fixed a crash bug that might appear when --delete was used and
- multiple source directories were specified.
-
- - The --backup code no longer attempts to create some directories
- over and over again (generating warnings along the way).
-
- - Fixed a bug in the reading of the secrets file (by the daemon) and
- the password file (by the client): the files no longer need to be
- terminated by a newline for their content to be read in.
-
- - If a file has a read error on the sending side, the receiver will
- no longer keep the resulting file unless the --partial option was
- specified.
-
- - Fixed an age-old crash problem with --read-batch on a local copy
- (rsync was improperly assuming --whole-file for the local copy).
-
- - Files specified in the daemon's "exclude" or "exclude from" config
- items are now excluded from being uploaded (if the module is not
- read-only) as well as downloaded.
-
- - When using --backup without a --backup-dir, rsync no longer preserves
- the modify time on directories. This avoids confusing NFS.
-
- - Fixed a bug in the daemon authentication code when using one of the
- batch-processing options.
-
- ENHANCEMENTS:
+ - 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).
- - Added the "write only" option to the daemon's config file.
+ - The combination of --verbose and --dry-run now mentions the full list
+ of changes that would be output without --dry-run.
- - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
- and documented all these options in the man page.
+ - Avoid a mkdir warning when removing a directory in the destination
+ that already exists in the --backup-dir.
- INTERNAL:
+ - An OS that has a binary mode for its files (such as cygwin) needed
+ setmode(fd, O_BINARY) called on the temp-file we opened with
+ mkstemp(). (Fix derived from the cygwin's 2.6.3 rsync package.)
- - Some cleanup in the exclude code has saved some memory and made
- things easier to maintain.
+ - Fixed a potential hang when verbosity is high, the client side is
+ the sender, and the file-list is large.
- - Use rsyserr() in the various places that were still calling
- rprintf() with strerror() as an arg.
+ - 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.
- BUILD CHANGES:
+ - Fixed an off-by-one error in the handling of --max-delete=N.
- - Added a "gen" target to rebuild most of the various generated
- files, including configure, config.h.in, the man pages, and
- proto.h.
+ - One place in the code wasn't checking if fork() failed.
- - The timestamp of the proto.h file is unaltered by "make proto"
- if the contents don't change.
+ - The "ignore nonreadable" daemon parameter used to erroneously affect
+ symlinks that pointed to a non-existent file. This has been fixed.
- DEVELOPER RELATED:
+ - If the OS does not have lchown() and a chown() of a symlink will
+ affect the referent of a symlink (as it should), we no longer try
+ to set the user and group of a symlink.
- - The scripts in the testsuite dir were cleaned up a bit.
+ - 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.
-NEWS for rsync 2.6.2 (30 Apr 2004)
-Protocol: 28 (unchanged)
-Changes since 2.6.1:
-
- BUG FIXES:
+ - 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.
- - Fixed a major bug in the sorting of the filenames when --relative
- is used for some sources (just sources such as "/" and "/*" were
- affected). This fix ensures that we ask for the right file-list
- item when requesting changes from the sender.
+ - One call to flush_write_file() was not being checked for an error.
- - Rsync now checks the return value of the close() function to
- better report disk-full problems on an NFS file system.
-
- - Restored the old daemon-server behavior of logging error messages
- rather than returning them to the user. (A better long-term fix
- will be sought in the future.)
-
- - An obscure uninitialized-variable bug was fixed in the uid/gid
- code. (This bug probably had no ill effects.)
-
- BUILD CHANGES:
+ - The --no-relative option was not being sent from the client to a
+ server sender.
- - Got rid of the configure check for sys/sysctl.h (it wasn't used
- and was causing a problem on some systems). Also improved the
- broken-largefile-locking test to try to avoid failure due to an
- NFS build-dir.
+ - 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 (e.g. rsync might have
+ exited with an error for large files).
- - Fixed a compile problem on systems that don't define
- AI_NUMERICHOST.
+ - Fixed a bug that would sometimes surface when using --compress and
+ sending a file with a block-size larger than 64K (either manually
+ specified, or computed due to the file being really large). Prior
+ versions of rsync would sometimes fail to decompress the data
+ properly, and thus the transferred file would fail its verification.
- - Fixed a compile problem in the popt source for compilers that
- don't support __attribute__.
+ - If a daemon can't open the specified log file (i.e. syslog is not
+ being used), die without crashing. We also output an error about
+ the failure on stderr (which will only be seen if --no-detach was
+ specified).
- DEVELOPER RELATED:
+ - A local transfer no longer duplicates all its include/exclude options
+ (since the forked process already has a copy of the exclude list,
+ there's no need to send them a set of duplicates).
- - Improved the testsuite's "merge" test to work on OSF1.
-
- - Two new diffs were added to the patches dir.

-NEWS for rsync 2.6.1 (26 Apr 2004)
-Protocol: 28 (changed)
-Changes since 2.6.0:
-
- SECURITY FIXES:
-
- - Paths sent to an rsync daemon are more thoroughly sanitized when
- chroot is not used. If you're running a non-read-only rsync
- daemon with chroot disabled, *please upgrade*, ESPECIALLY if the
- user privs you run rsync under is anything above "nobody".
+ - When --progress is specified, the output of items that the generator
+ is creating (e.g. dirs, symlinks) is now integrated into the progress
+ output without overlapping it. (Requires protocol 29.)
ENHANCEMENTS:
- - Lower memory use, more optimal transfer of data over the socket,
- and lower CPU usage (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.
-
- - Documentation changes now attempt to describe some often mis-
- understood features more clearly.
-
- 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
- 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)
-
- - When using --cvs-exclude, the exclude items we get from a
- per-directory's .cvsignore file once again only affect that one
- directory (not all following directories too). The items are also
- now properly word-split and parsed without any +/- prefix parsing.
-
- - 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 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.
+ - 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 the receiving side incrementally as each directory in the
+ transfer is being processed. This makes it more efficient than the
+ default, before-the-transfer behavior, which is now available as
+ --delete-before (and is still the default --delete-WHEN option that
+ will be chosen if --delete or --delete-excluded is specified without
+ a --delete-WHEN choice). All the --del* options infer --delete, so
+ an rsync daemon that refuses "delete" will still refuse to allow any
+ file-deleting options.
+
+ - All the --delete-WHEN options are now more memory efficient:
+ Previously an entire duplicate set of file-list objects was created
+ on the receiving side for the entire destination hierarchy. The new
+ algorithm only creates one directory of objects at a time (for files
+ inside the transfer).
+
+ - Added support for specifying multiple --compare-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 when a client connects (e.g. a hang or an abort).
+
+ - 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". A command-line option
+ will take precedence over a config-file option, as expected.
+
+ - 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 and
+ --link-dest. (Requires protocol 29.)
+
+ - 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
+ internal option kluges (e.g. the age-old use of "-r --exclude="/*/*"
+ for a non-recursive listing). This option is used automatically
+ (behind the scenes) 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. (Promoted from
+ the patches dir.)
+
+ - 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. Protocol 29 is needed for full filter-rule support, but
+ backward-compatible rules work with earlier protocol versions.
+ (Promoted from the patches dir and enhanced.)
+
+ - 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.)
+
+ - The sender and the generator now double-check the file-list index
+ they are given, and refuse to try to do a file transfer on a
+ non-file index (since that would indicate that something had gone
+ very wrong).
+
+ - Added the --itemize-changes (-i) option, which is a way to output a
+ more detailed list of what files changed in any way and how they
+ changed. The effect is the same as specifying a --log-format of
+ "%i %n%L" (see the rsyncd.conf manpage). Works with --dry-run too.
+
+ - Added the --fuzzy option, which attempts to find a basis file for a
+ file that is being created from scratch. The current algorithm
+ only looks in the destination directory for the created file, but
+ it does attempt to find a match based on size/mod-time (in case the
+ file was renamed with no other changes) as well as based on a fuzzy
+ name-matching algorithm. This option requires protocol 29 because
+ it needs the new file-sorting order. (Promoted from patches dir
+ and enhanced.)
+
+ - Added the --remove-sent-files option, which lets you move files
+ between systems.
+
+ - When building under windows, the default for --daemon is now to
+ avoid detaching, requiring the new --detach option to force rsync
+ to detach.
+
+ - Improved the option descriptions in the --help text.
+
+ SUPPORT FILES:
+
+ - Added atomic-rsync to the support dir: 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 mnt-excl to the support dir: a perl script 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 savetransfer.c to the support dir: 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 rrsync to the support dir: this is 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.
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.
+ - Added better checking of the checksum-header values that come over
+ the socket.
- - Some cleanup of the variable types make the code more consistent.
+ - Merged a variety of file-deleting functions into a single function so
+ that it is easier to maintain.
- - Reduced memory requirements of hard link preservation.
- (J.W. Schultz)
+ - Improved the type of some variables (particularly blocksize vars) for
+ consistency and proper size.
- - Implemented a new algorithm for hard-link handling that speeds up
- the code significantly. (J.W. Schultz and Wayne Davison)
+ - Got rid of the uint64 type (which we didn't need).
- - 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.
+ - Use a slightly more compatible set of core #include directives.
- - 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)
+ - Defined int32 in a way that ensures that the build dies if we can't
+ find a variable with at least 32 bits.
- - More optimal data transmission for --hard-links (protocol 28).
+ - The daemon's "read only" config item now sets an internal read_only
+ variable that makes extra sure that no write/delete calls on the
+ read-only side can succeed.
- - More optimal data transmission for --checksum (protocol 28).
+ PROTOCOL DIFFERENCES FOR VERSION 29:
- - Less memory is used when --checksum is specified.
+ - A 16-bit flag-word is transmitted after every file-list index. This
+ indicates what is changing between the sender and the receiver. The
+ generator now transmits an index and a flag-word to indicate when
+ dirs and symlinks have changed (instead of producing a message),
+ which makes the outputting of the information more consistent and
+ less prone to screen corruption (because either the receiver or the
+ sender is now outputting all the file-change info).
- - Less memory is used in the file list (a per-file savings).
+ - If --inplace is specified, the generator flags any transfer that is
+ using an alternate basis file so that the sender can use the entire
+ file in the rsync algorithm (unlike a normal --inplace update).
- - 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.
+ - The sending of exclude names is done using filter-rule syntax. This
+ means that all names have a prefixed rule indicator, even excludes
+ (which used to be sent as a bare pattern, when possible). The -C
+ option will include the per-dir .cvsignore merge file in the list of
+ filter rules so it is positioned correctly (unlike in some older
+ transfer scenarios).
- - 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)
+ - Rsync sorts the filename list in a different way: it sorts the subdir
+ names after the non-subdir names for each dir's contents, and it
+ always puts a dir's contents immediately after the dir's name in the
+ list. (Previously an item named "foo.txt" would sort in between
+ directory "foo/" and "foo/bar".)
- - 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 (which mainly affected hard-link messages and
- verbose --stats output).
+ - When talking to a protocol 29 rsync daemon, a list-only request
+ is able to note this before the options are sent over the wire and
+ the new --list-only option is included in the options.
- - Improved the internal uid/gid code to be more portable and a
- little more optimized.
+ - When the --stats bytes are sent over the wire (or stored in a batch),
+ they now include two elapsed-time values: one for how long it took to
+ build the file-list, and one for how long it took to send it over the
+ wire (each expressed in thousandths of a second).
- - 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 (with both ends of the
- connection are using protocol 28). Note that optimizations in the
- binary protocol for sending the device numbers often results in
- fewer bytes being used than before, even though more precision is
- now available.
+ - When --delete-excluded is specified with some filter excludes, a
+ client sender will now initiate a send of the filter rules to the
+ receiver (older protocols used to omit the sending of excludes in
+ this situation since there were no receiver-specific rules that
+ survived --delete-excluded back then). Note that, as with all the
+ filter-list sending, only items that are significant to the other
+ side will actually be sent over the wire, so the filter-rule list
+ is often empty in this scenario.
- - Some cleanup of the exclude/include structures and its code made
- things clearer (internally), simpler, and more efficient.
-
- - 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. (Note that the
- batch code is still considered to be experimental.)
+ - A protocol-29 batch file includes a bit for the setting of the --dirs
+ option. Also, the shell script created by --write-batch will use the
+ --filter option instead of --exclude-from to capture any filter rules.
BUILD CHANGES:
- - The configure script now accepts --with-rsyncd-conf=PATH to
- override the default value of the /etc/rsyncd.conf file.
-
- - Fixed configure bug when running "./configure --disable-ipv6".
-
- - Fixed compilation problem on Tru64 Unix (having to do with
- sockaddr.sa_len and sockaddr.sin_len).
-
- DEVELOPER RELATED:
-
- - Fixed "make test" bug when build dir is not the source dir.
-
- - Added a couple extra diffs in the "patches" dir, removed the ones
- that got applied, and rebuilt the rest.
+ - Handle an operating system that use mkdev() in place of makedev().
+ - Improved configure to better handle cross-compiling.
