+NEWS for rsync 3.0.1 (UNRELEASED)
+Protocol: 30 (unchanged)
+Changes since 3.0.0:
- SECURITY FIXES:
+ BUG 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".
+ - Fixed a crash bug when a single-use rsync daemon (via remote shell) was
+ run without specifying a --config=FILE option.
- ENHANCEMENTS:
+ - Fixed a crash when backing up a directory that has a default ACL.
- - Lower memory use, more optimal transfer of data over the socket,
- and lower CPU usage (see the INTERNAL section for details).
+ - Fixed a bug in the handling of xattr values that could cause rsync to
+ not think that a file's extended attributes are up-to-date.
- - The RSYNC_PROXY environment variable can now contain a
- "USER:PASS@" prefix before the "HOST:PORT" information.
- (Bardur Arantsson)
+ - Fixed the working of --fake-super with --link-dest and --xattrs.
- - 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.
+ - Fixed a hang when combining --dry-run with --remove-source-files.
- - The configure script now accepts --with-rsyncd-conf=PATH to
- override the default value of the /etc/rsyncd.conf file.
+ - Fixed the building of the rounding.h file on systems that need custom
+ CPPFLAGS to be used. Also improved the error reporting if the building
+ of rounding.h fails.
- - Added a couple extra diffs in the "patches" dir, removed the ones
- that got applied, and rebuilt the rest.
+ - Fixed the use of the --protect-args (-s) option when talking to a daemon.
- - Documentation changes now attempt to describe some often mis-
- understood features more clearly.
+ - Fixed the --ignore-existing option's protection of files on the receiver
+ that are non-regular files on the sender (e.g. if a symlink or a dir on
+ the sender is trying to replace a file on the receiver). The reverse
+ protection (protecting a dir/symlink/device from being replaced by a
+ file) was already working.
- BUG FIXES:
+ - Fixed an assert failure if --hard-links is combined with an option that
+ can cause a file in a set of hard-linked files to be skipped (i.e. if
+ --append, --ignore-existing, etc. affects one or more files in a hard-
+ linked set of files, but not all of them).
+
+ - Avoid setting the time on a directory that already has the modify time
+ that we're setting. This avoids tweaking the dir's ctime.
+
+ - Fixed the 'T'-flag itemizing of symlinks when --time isn't preserved.
+
+ - Fixed a glitch in the itemizing of permissions with the -E option.
+
+ - Added the 'c'-flag to the itemizing of non-regular files so that the
+ itemized output doesn't get hidden if there were no attribute changes,
+ and also so that the itemizing of a --copy-links run will distinguish
+ between copying an identical non-regular file and the creation of a
+ revised version with a new value (e.g. symlink referent, device
+ numbers).
+
+ - The --append option's restricting of transfers to those that add data no
+ longer prevents the updating of non-content changes to otherwise up-to-
+ date files (i.e. those with the same content but differing permissions,
+ ownership, xattrs, etc.).
+
+ - Don't allow --fake-super to be specified with -XX (double --xattrs)
+ because they conflict. If a daemon has "fake super" enabled, it
+ automatically downgrades a -XX request to -X.
+
+ - A daemon doesn't try to auto-refuse the "iconv" option if iconv-support
+ wasn't compiled in to the daemon (avoiding a warning in the logs).
- - 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.
+ - Fixed the support/rrsync script to work with the latest options that
+ rsync sends (including its flag-specifying use of -e to the server).
+
+ ENHANCEMENTS:
+
+ - When getting an error while asking an older rsync daemon for a file
+ listing, rsync will try to notice if the error is a rejection of the
+ --dirs (-d) option and let the user know how to work around the issue.
+
+ - Added a few more --no-OPTION overrides.
+
+ - Improved the documentation of the --append option.
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.)
+ - Fixed a couple minor bugs in the included popt library (ones which I
+ sent to the official popt project for inclusion in the 1.14 release).
+
+ - Fixed a stat() call that should have been do_stat() so that the proper
+ normal/64-bit stat() function gets called. (Was in an area that should
+ not have caused problems, though.)
+
+ DEVELOPER RELATED:
+
+ - The configure script tries to get the user's compiler to not warn about
+ unused function parameters if the build is not including one or more of
+ the ACL/xattrs/iconv features.
+
+ - The configure script now has better checks for figuring out if the
+ included popt should be used or not.
+
+ - Updated the build scripts to work with a revised FTP directory
+ structure.
