+NEWS for rsync 2.6.5 (UNRELEASED)
+Protocol: 29 (unchanged)
+Changes since 2.6.4:
+
+ OUTPUT CHANGES:
+
+ - Non-printable chars in filenames are now output using backslash-
+ escaped characters rather than '?'s. Any non-printable character is
+ output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash
+ is now output as "\\". Rsync also uses your locale setting, which
+ can make it treat fewer high-bit characters as non-printable.
+
+ - If rsync received an empty file list when pulling files, it would
+ output a "nothing to do" message and exit with a 0 (success) exit
+ status, even if the remote rsync returned an error (it did not do
+ this under the same conditions when pushing files). This was changed
+ to make the pulling behavior the same as the pushing behavior: we
+ now do the normal end-of-run outputting (depending on options) and
+ exit with the appropriate exit status.
+
+ BUG FIXES:
+
+ - A crash bug was fixed when a daemon had its "path" set to "/", did
+ not have chroot enabled, and used some anchored excludes in the
+ rsyncd.conf file.
+
+ - Fixed a bug in the transfer of a single file when -H is specified
+ that might have caused an infinite loop or perhaps a crash.
+
+ - Fixed a case where the generator might try to tweak the write
+ permissions of a read-only directory in list-only mode.
+
+ - If --compare-dest or --link-dest uses a locally-copied file as the
+ basis for an updated version, log this better when --verbose or -i
+ is in effect.
+
+ - Fixed the accidental disabling of --backup during the --delete-after
+ processing.
+
+ - Restored the ability to use the --address option in client mode (in
+ addition to its use in daemon mode).
+
+ - Make sure that some temporary progress information from the delete
+ processing does not get left on the screen when it is followed by a
+ newline.
+
+ - When --existing skips a directory with extra verbosity, refer to it
+ as a "directory", not a "file".
+
+ - When transferring a single file to a different-named file, any
+ generator messages that are source-file related no longer refer to
+ the file by the destination filename.
+
+ - Fixed a bug where hard-linking a group of files might fail if the
+ generator hasn't created a needed destination directory yet.
+
+ - Fixed a bug where a hard-linked group of files that is newly-linked
+ to a file in a --link-dest dir doesn't link the files from the rest
+ of the cluster.
+
+ - When deleting files with the --one-file-system (-x) option set, rsync
+ no longer tries to remove files from inside a mount-point on the
+ receiving side.
+
+ - Fixed a compatibility problem when using --cvs-ignore (-C) and
+ sending files to an older rsync without using --delete.
+
+ - Make sure that a "- !" or "+ !" include/exclude pattern does not
+ trigger the list-clearing action that is reserved for "!".
+
+ - Avoid a timeout in the generator when the sender/receiver aren't
+ handling the generator's checksum output quickly enough.
+
+ - Fixed the ommission of some directories in the delete processing when
+ --relative (-R) was combined with a source path that had a trailing
+ slash.
+
+ - Make sure that --max-size doesn't affect a device or a symlink.
+
+ - Make sure that a system with a really small MAXPATHLEN does not cause
+ the buffers in readfd_unbuffered() to be too small to receive normal
+ messages. (This mainly affected Cygwin.)
+
+ - If a source filename ends with "..", treat it as if "../" had been
+ specified (so that we don't copy files to the parent dir of the
+ destination).
+
+ - If --delete is combined with a file-listing rsync command (i.e. no
+ transfer is happening), avoid outputting a warning that we couldn't
+ delete anything.
+
+ - If --stats is specified with --delete-after, ensure that all the
+ "deleting" messages are output before the statistics.
+
+ - Improved one "if" in the deletion code that was only checking errno
+ for ENOTEMPTY when it should have also been checking for EEXIST.
ENHANCEMENTS:
- * Lower memory use and more optimal transfer of data over
- the socket (see the INTERNAL section for details).
+ - Added the --only-write-batch=FILE option that may be used (instead
+ of --write-batch=FILE) to create a batch file without doing any
+ actual updating of the destination. This allows you to divert all
+ the file-updating data away from a slow data link (as long as you
+ are pushing the data to the remote server when creating the batch).
- * The RSYNC_PROXY environment variable can now contain a
- "USER:PASS@" prefix before the "HOST:PORT" information.
- (Bardur Arantsson)
+ - When the generator is taking a long time to fill up its output buffer
+ (e.g. if the transferred files are few, small, or missing), it now
+ periodically flushes the output buffer so that the sender/receiver
+ can get started on the files sooner rather than later.
- * 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.
+ - Improved the keep-alive code to handle a long silence between the
+ sender and the receiver that can occur when the sender is receiving
+ the checksum data for a large file.
- * The configure script now accepts --with-rsyncd-conf=PATH
- to override the default value of the /etc/rsyncd.conf file.
+ - Improved the auth-errors that are logged by the daemon to include
+ some information on why the authorization failed (wrong user,
+ password mismatch, etc.). (The client-visible message is unchanged.)
- * Added a couple extra diffs in the "patches" dir, removed the
- ones that got applied, and rebuilt the rest.
+ - Improved the client's handling of an "@ERROR" from a daemon so that
+ it does not complain about an unexpectedly closed socket (since we
+ really did expect the socket to close).
- BUG FIXES:
+ - If the daemon can't open the log-file specified in rsyncd.conf, fall
+ back to using syslog (and log an appropriate warning). This is
+ better than what was typically a totally silent failure (since a
+ daemon is not usually run with the --no-detach option that was
+ necessary to see the error on stderr).
- * 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
- directory's .cvsignore file once again only affect that one
- directory (and not all following directories too). The
- items are also now properly word-split and parsed without
- any +/- prefix munging.
-
- * 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.
+ - The man pages now consistently refer to an rsync daemon as a "daemon"
+ to distinguish it from a server in a non-daemon transfer.
+
+ - Made a small change to the rrsync script (restricted rsync -- in the
+ support dir) to make a read-only server reject all --remove-* options
+ when sending files (to future-proof it against the possibility of
+ other similar options being added at some point).
INTERNAL:
- * Most of the I/O is now buffered, which results in a pretty
- large speedup when running under MS Windows. (Craig Barratt)
+ - Rsync now calls setlocale(LC_CTYPE, "") to enable isprint() to better
+ discern which filename characters need to be escaped in messages.
- * Optimizations to the name-handling/comparing code have made
- some significant reductions in user-CPU time for large file
- sets.
+ - Improved the naming of the log-file open/reopen/close functions.
- * Some variable-type cleanup that makes the code more consistent.
+ - Removed some protocol compatibility code that was only needed to help
+ someone running a pre-release of 2.6.4.
- * Reduced memory requirements of hard link preservation.
- (J.W. Schultz)
+ BUILD CHANGES:
- * Implemented a new algorithm for hard-link handling that speeds
- up the code significantly. (J.W. Schultz and Wayne Davison)
+ - Fixed a bug in the SUPPORT{,_HARD}_LINKS defines which prevented
+ rsync from being built without symlink or hard-link support.
- * 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.
+ - You can use --disable-locale to turn off any use of setlocale().
+
+ - Configure now disables the use of mkstemp() under HP-UX (since they
+ refuse to fix its broken handling of large files).
+
+ - Configure now explicitly checks for the lseek64() function so that
+ the code can use HAVE_LSEEK64 instead of inferring lseek64()'s
+ presence based on the presence of the off64_t type.
+
+ - Some minor enhancements to the test scripts.
- * 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 (the latter mainly affected
- hard-link messages and verbose --stats output).
-
- * 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.
-
- * 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. Note that optimizations
- in the binary protocol often sends the device data using fewer
- bytes than before, even though more precision is now available.
-
- * Some cleanup of the exclude/include structures and its code
- made things clearer, simpler, and more efficient.
+ - Added a few new diffs to the patches dir, including a patch that
+ enables the optional copying of extended attributes.
