+NEWS for rsync 2.6.7 (UNRELEASED)
+Protocol: 29 (unchanged)
+Changes since 2.6.6:
BUG FIXES:
- - 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.
+ - Fixed a really old bug that caused --checksum (-c) to checksum all the
+ files encountered during the delete scan (ouch).
- - Rsync now checks the return value of the close() function to
- better report disk-full problems on an NFS file system.
+ - Made hard-links work with symlinks and devices again.
- - 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.)
+ - If a device-file/special-file changes permissions, rsync now updates the
+ permissions without recreating the file.
- - An obscure uninitialized-variable bug was fixed in the uid/gid
- code. (This bug probably had no ill effects.)
+ - 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.
- - 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.
+ - 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 compile problem on systems that don't define
- AI_NUMERICHOST.
+ - Reject the combination of --inplace and --sparse since the sparse-output
+ algorithm doesn't work when overwriting existing data.
- - Fixed a compile problem in the popt source for compilers that
- don't support __attribute__.
+ - Fixed the directory name in the error that is output when pop_dir()
+ fails.
- INTERNAL:
-
- - Improved the testsuite's "merge" test to work on OSF1.
+ - Really fixed the parsing of a "!" entry in .cvsignore files this time.
- - Two new diffs were added to the patches dir.
+ - 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).

-NEWS for rsync 2.6.1 (26 Apr 2004)
-Protocol: 28 (changed)
-Changes since 2.6.0:
+ - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
+ the exit status properly and generate a better error.
- SECURITY FIXES:
+ - Fixed some glitches in the double-verbose output when using --copy-dest,
+ --link-dest, or --compare-dest.
- - 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".
+ - Fixed the matching of the dont-compress items (e.g. *.gz) against files
+ that have a path component containing a slash.
ENHANCEMENTS:
- - Lower memory use, more optimal transfer of data over the socket,
- and lower CPU usage (see the INTERNAL section for details).
+ - Added the --append option that makes rsync append data onto files
+ that are longer on the source than the destination (this includes new
+ files).
- - The RSYNC_PROXY environment variable can now contain a
- "USER:PASS@" prefix before the "HOST:PORT" information.
- (Bardur Arantsson)
+ - Added the --min-size=SIZE option to exclude small files from the
+ transfer.
- - 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.
+ - Added the --compress-level option to allow you to set how aggressive
+ rsync's compression should be (this option implies --compress).
- - The configure script now accepts --with-rsyncd-conf=PATH to
- override the default value of the /etc/rsyncd.conf file.
+ - 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).
- - Added a couple extra diffs in the "patches" dir, removed the ones
- that got applied, and rebuilt the rest.
+ - The options --human-readable (-h) and --si change the output of the
+ --stats and the end-of-run summary to be easier to read.
- - Documentation changes now attempt to describe some often mis-
- understood features more clearly.
+ - If lutimes() and/or lchmod() are around, use them to allow the
+ preservation of attributes on symlinks.
- BUG FIXES:
+ - 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 information about the transfer.)
+
+ - 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).
+
+ - 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.
+
+ - Added the --chmod=MODE option that allows the destination permissions
+ to be changed from the source permissions. E.g. --chmod=g+w,o-rwx
+
+ - Allow the --temp-dir option to be specified when starting a daemon,
+ which sets the default temporary directory for incoming files.
+
+ - If --delete is combined with --dirs without --recursive, rsync will
+ now delete in any directory whose content is being synchronized.
- - 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
- 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 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.
+ - If --backup is combined with --delete without --backup-dir (and
+ without --delete-excluded), we add a "protect" filter-rule to ensure
+ that files with the backup suffix are not deleted.
+
+ - 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 the fifth file
+ to be transferred, and we still need to check 8383 more files out of
+ a total of 9999.
+
+ - Some minor documentation improvements.
+
+ - Updated some diffs in the patches 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.
-
- - Some cleanup of the variable types make the code more consistent.
-
- - 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.
-
- - 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)
-
- - More optimal data transmission for --hard-links (protocol 28).
-
- - More optimal data transmission for --checksum (protocol 28).
-
- - Less memory is used when --checksum is specified.
-
- - Less memory is used in the file list (a per-file savings).
-
- - 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.
-
- - 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)
-
- - 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).
-
- - Improved the internal uid/gid code to be more portable and a
- little more optimized.
-
- - 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.
-
- - 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.)
+ - Some buffer sizes were expanded a bit, particularly on systems where
+ MAXPATHLEN is overly small (e.g. cygwin).
+
+ - If io_printf() tries to format more data than fits in the buffer, exit
+ with an error instead of transmitting a truncated buffer.
+
+ - If a va_copy macro is defined, lib/snprintf.c will use it when defining
+ the VA_COPY macro.
+
+ - Reduced the amount of stack memory needed for each level of directory
+ recursion by nearly MAXPATHLEN bytes.
+
+ DEVELOPER RELATED:
+
+ - 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.
