+NEWS for rsync 2.6.3 (UNRELEASED)
+Protocol: 28 (unchanged)
+Changes since 2.6.2:
- ENHANCEMENTS:
+ BUG FIXES:
- * Lower memory use and more optimal transfer of data over
- the socket (see the INTERNAL section for details).
+ - Fixed a crash bug that might appear when --delete was used and
+ multiple source directories were specified.
- * The RSYNC_PROXY environment variable can now contain a
- "USER:PASS@" prefix before the "HOST:PORT" information.
- (Bardur Arantsson)
+ - Fixed the 32-bit truncation of the file length when generating the
+ checksums.
- * 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.
+ - The --backup code no longer attempts to create some directories
+ over and over again (generating warnings along the way).
- * The configure script now accepts --with-rsyncd-conf=PATH
- to override the default value of the /etc/rsyncd.conf file.
+ - 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.
- * Added a couple extra diffs in the "patches" dir, removed the
- ones that got applied, and rebuilt the rest.
+ - 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. (Note: both sides must be running 2.6.3 for this to
+ work -- older receivers always keep the file, and older senders
+ don't tell the receiver that the file was not read correctly.)
- BUG FIXES:
+ - If a file gets resent in a single transfer and the --backup option
+ is enabled, rsync no longer performs a duplicate backup (losing the
+ original file in the process).
- * 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.
+ - Fixed an age-old crash problem with --read-batch on a local copy
+ (rsync was improperly assuming --whole-file for the local copy).
- * 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.
+ - Files specified in the daemon's "exclude" or "exclude from" config
+ items are now excluded from being uploaded (assuming that the module
+ allows uploading at all) in addition to the old download exclusion.
- * 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.
+ - Got rid of a potential hang in the receiver when near the end of a
+ phase.
- * Fixed a byte-order problem in --batch-mode on big-endian
- machines. (Jay Fenlason)
+ - When using --backup without a --backup-dir, rsync no longer preserves
+ the modify time on directories. This avoids confusing NFS.
- * Fixed configure bug when running "./configure --disable-ipv6".
+ - When --copy-links (-L) is specified, we now output a separate error
+ for a symlink that has no referent instead of claiming that a file
+ "vanished".
- * Fixed "make test" bug when build dir is not the source dir.
+ - Error messages from the daemon server's option-parsing (such as
+ refused options) now get sent back to the client (the server used
+ to just exit because the socket wasn't in the right state to send
+ the message).
- * 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).
+ - Most errors that occur during a daemon transfer are now returned to
+ the user in addition to being logged (some messages are intended to
+ be daemon-only).
- * 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 a bug in the daemon authentication code when using one of the
+ batch-processing options.
- * 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.
+ - We try to work around some buggy IPv6 implementations that fail to
+ implement IPV6_V6ONLY. This should fix the "address in use" error
+ that some daemons get when running on an OS with a buggy IPv6
+ implementation. Also, if the new code gets this error, we might
+ suggest that the user specify --ipv4 or --ipv6 (if we think it will
+ help).
- * Fixed the "refuse options" setting in the rsyncd.conf file.
+ ENHANCEMENTS:
- * 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 remaped
- mount of the original filesystem could get discovered on a
- disk we should be ignoring.
+ - Added --keep-dirlinks (-K), which allows you to symlink a directory
+ onto another partition on the receiving side and have rsync treat it
+ as matching a normal directory from the sender.
- * 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).
+ - Added the "write only" option to the daemon's config file.
- * Fixed compilation problem on Tru64 Unix (having to do with
- sockaddr.sa_len and sockaddr.sin_len).
+ - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
+ and documented all these options in the man page.
- * Fixed a compatibility problem interacting with older rsync
- versions that might send us an empty suffix without telling us
- about the backup-dir.
+ - Improved the handling of the --bwlimit option so that it's less
+ bursty, more accurate, and works properly over a larger range of
+ values.
- * 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.
+ - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and
+ SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address.
- INTERNAL:
+ - Added the --checksum-seed=N option for advanced users.
- * Most of the I/O is now buffered, which results in a pretty
- large speedup when running under MS Windows. (Craig Barratt)
+ - Batch writing/reading has a brand-new implementation that is simpler,
+ fixes a few weird problems with the old code (such as no longer
+ sprinkling the batch files into different dirs or even onto different
+ systems), and is much less intrusive into the code (making it easier
+ to maintain for the future). The new code generates just one data
+ file instead of three, which makes it possible to read the batch via
+ stdin. Also, the old requirement of using the same fixed checksum-
+ seed for all batch processing has been removed. (Chris Shoemaker)
- * Optimizations to the name-handling/comparing code have made
- some significant reductions in user-CPU time for large file
- sets.
+ INTERNAL:
- * Some variable-type cleanup that makes the code more consistent.
+ - Some cleanup in the exclude code has saved some per-exclude memory
+ and made the code easier to maintain.
- * Reduced memory requirements of hard link preservation.
- (J.W. Schultz)
+ - Improved the argv-overflow checking for a remote command that has
+ a lot of args.
- * Implemented a new algorithm for hard-link handling that speeds
- up the code significantly. (J.W. Schultz and Wayne Davison)
+ - Use rsyserr() in the various places that were still calling
+ rprintf() with strerror() as an arg.
- * 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.
+ - If an rsync daemon is listening on multiple sockets (to handle both
+ IPv4 and IPv6 to a single port), we now close all the unneeded file
+ handles after we accept a connection (we used to close just one of
+ them).
- * 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)
+ - Optimized away a loop in hash_search().
- * More optimal data transmission for --hard-links (protocol 28).
+ BUILD CHANGES:
- * More optimal data transmission for --checksum (protocol 28).
+ - Added a "gen" target to rebuild most of the generated files,
+ including configure, config.h.in, the man pages, and proto.h.
- * Less memory is used when --checksum is specified.
+ - If "make proto" doesn't find some changes in the prototypes, the
+ proto.h file is left untouched (its time-stamp used to always be
+ updated).
- * Less memory is used in the file list (a per-file savings).
+ - The variable $STRIP (that is optionally set by the install-strip
+ target's rule) was changed to $INSTALL_STRIP because some systems
+ have $STRIP set in the environment.
- * 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.
+ - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined.
- * 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)
+ DEVELOPER RELATED:
- * 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).
+ - The scripts in the testsuite dir were cleaned up a bit.
- * 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.
+ - Some new diffs were added to the patches dir, and some accepted
+ ones were removed.
- * Improved the internal uid/gid code to be more portable and
- a little more optimized.
