+NEWS for rsync 2.6.5 (UNRELEASED)
+Protocol: 29 (unchanged)
+Changes since 2.6.4:
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.
+ - 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.
- - 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.)
+ - If rsync received an empty file list when pulling files, it would
+ output an "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.
- - The "%o" (operation) log format 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.
-
BUG FIXES:
- - 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).
+ - 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.
- - The combination of --verbose and --dry-run now mentions the full list
- of changes that would be output without --dry-run.
+ - 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.
- - Avoid a mkdir warning when removing a directory in the destination
- that already exists in the --backup-dir.
+ - Fixed a case where the generator might try to tweak the write
+ permissions of a read-only directory in list-only mode.
- - 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.)
+ - 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 a potential hang when verbosity is high, the client side is
- the sender, and the file-list is large.
+ - Fixed the accidental disabling of --backup during the --delete-after
+ processing.
- - 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.
+ - Restored the ability to use the --address option in client mode (in
+ addition to its use in daemon mode).
- - Fixed an off-by-one error in the handling of --max-delete=N.
+ - 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.
- - One place in the code wasn't checking if fork() failed.
+ - When --existing skips a directory with extra verbosity, don't refer
+ to it as a "file".
- - The "ignore nonreadable" daemon parameter used to erroneously affect
- symlinks that pointed to a non-existent file. This has been fixed.
+ - 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.
- - 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.
+ - Fixed a bug where hard-linking a group of files might fail if the
+ generator hasn't created the destination directory yet.
- - 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.
+ - 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 --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.
+ - 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.
- - One call to flush_write_file() was not being checked for an error.
+ - Fixed a compatibility problem when using --cvs-ignore (-C) and
+ sending files to an older rsync without using --delete.
- - The --no-relative option was not being sent from the client to a
- server sender.
-
- - 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 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 to decompress the data
- properly, and thus the transferred file would fail its verification.
-
- - 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).
-
- - 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).
-
- - 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.)
+ - Fixed the ommission of some directories in the delete processing when
+ --relative (-R) was combined with a source path that had a trailing
+ slash.
ENHANCEMENTS:
- - 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 on 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 (that 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.
-
- - Added the --copy-dest option, which works like --link-dest except
- that it includes copies of identical files.
-
- - Added support for specifying multiple --compare-dest, --copy-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,
- --link-dest, and (the new) --copy-dest options. (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:
-
- - Added better checking of the checksum-header values that come over
- the socket.
-
- - Merged a variety of file-deleting functions into a single function so
- that it is easier to maintain.
+ - 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).
- - Improved the type of some variables (particularly blocksize vars) for
- consistency and proper size.
+ - 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.
- - Got rid of the uint64 type (which we didn't need).
+ - 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.)
- - Use a slightly more compatible set of core #include directives.
+ - 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).
- - Defined int32 in a way that ensures that the build dies if we can't
- find a variable with at least 32 bits.
+ - If the daemon can't open the log-file specified in rsyncd.conf, fall
+ back to using syslog. This is better than a (typically) totally
+ silent failure (since a daemon is not usually run with --no-detach).
- - 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.
+ - The man pages now consistently refer to an rsync daemon as a "daemon"
+ to distinguish it from a server in a non-daemon transfer.
- PROTOCOL DIFFERENCES FOR VERSION 29:
-
- - 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, which makes the outputting of the
- information more consistent and less prone to screen corruption (it
- resorts to the old-style outputting of generator-created change-
- messages for older protocol versions).
-
- - 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 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).
-
- - 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".)
-
- - 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.
+ INTERNAL:
- - 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).
+ - Rsync now calls setlocale(LC_CTYPE, "").
- - 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.
+ BUILD CHANGES:
- - 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.
+ - Fixed a bug in the SUPPORT{,_HARD}_LINKS defines which prevented
+ rsync from being built without symlink or hard-link support.
- BUILD CHANGES:
+ - You can use --disable-locale to turn off any use of setlocale().
- - Handle an operating system that use mkdev() in place of makedev().
+ - Configure now disables the use of mkstemp() under HP-UX (since they
+ refuse to fix its broken handling of large files).
- - Improved configure to better handle cross-compiling.
+ - 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.
