+NEWS for rsync 2.6.7 (UNRELEASED)
Protocol: 29 (unchanged)
-Changes since 2.6.4:
+Changes since 2.6.6:
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
- should make it treat fewer high-bit characters as non-printable, as
- appropriate.
+ - The letter 'D' in the itemized output was being used for both devices
+ (character or block) as well as other special files (such as fifos and
+ named sockets). This has changed to separate non-device special files
+ under the 'S' designation (e.g. "cS+++++++ path/fifo"). See also the
+ "--specials" option, below.
+
+ - The way rsync escapes unreadable characters has changed. First, rsync
+ now has support for recognizing valid multibyte character sequences in
+ your current locale, allowing it to escape fewer characters than before
+ for a locale such as UTF-8. Second, it now uses an escape idiom of
+ "\#123", which is the literal string "\#" followed by exactly 3 octal
+ digits. Rsync no longer doubles a backslash character in a filename
+ (e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only
+ escapes a backslash that is followed by a hash-sign and 3 digits (0-9)
+ (e.g. it will output "foo\#134#789" when copying "foo\#789"). See also
+ the --8-bit-output (-8) option, mentioned below.
+
+ Script writers: the local rsync is the one that outputs escaped names,
+ so if you need to support unescaping of filenames for older rsyncs, I'd
+ suggest that you parse the output of "rsync --version" and only use the
+ old unescaping rules for 2.6.5 and 2.6.6.
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 really old bug that caused --checksum (-c) to checksum all the
+ files encountered during the delete scan (ouch).
+
+ - Fixed a potential hang in a remote generator: when the receiver gets a
+ read-error on the socket, it now signals the generator about this so that
+ the generator does not try to send any of the terminating error messages
+ to the client (avoiding a potential hang in some setups).
+
+ - Made hard-links work with symlinks and devices again.
+
+ - If the sender gets an early EOF reading a source file, we propagate this
+ error to the receiver so that it can discard the file and try requesting
+ it again (which is the existing behavior for other kinds of read errors).
+
+ - If a device-file/special-file changes permissions, rsync now updates the
+ permissions without recreating the 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.
+ - 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.
- - Fixed a case where the generator might try to tweak the write
- permissions of a read-only directory in list-only mode.
+ - 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.
- - 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.
+ - Reject the combination of --inplace and --sparse since the sparse-output
+ algorithm doesn't work when overwriting existing data.
- - Fixed the accidental disabling of --backup during the --delete-after
- processing.
+ - Fixed the directory name in the error that is output when pop_dir()
+ fails.
- - Restored the ability to use the --address option in client mode (in
- addition to its use in daemon mode).
+ - Really fixed the parsing of a "!" entry in .cvsignore files this time.
- - 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.
+ - 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).
- - When --existing skips a directory with extra verbosity, don't refer
- to it as a "file".
+ - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
+ the exit status properly and generate a better error.
- - 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 some glitches in the double-verbose output when using --copy-dest,
+ --link-dest, or --compare-dest. Also improved how the verbose output
+ handles hard-links (within the transfer) that had an up-to-date alternate
+ "dest" file, and copied files (via --copy-dest).
- - Fixed a bug where hard-linking a group of files might fail if the
- generator hasn't created the destination directory yet.
+ - Fixed the matching of the dont-compress items (e.g. *.gz) against files
+ that have a path component containing a slash.
- - 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.
+ - If code reading a filter/exclude file an EINTR error, rsync now clears
+ the error flag on the file handle so it can keep on reading.
- - 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.
+ - If --relative is active, the sending side cleans up trailing "/" or "/."
+ suffixes to avoid triggering a bug in older rsync versions. Also, we now
+ reject a ".." dir if it would be sent as a relative dir.
- - Fixed a compatibility problem when using --cvs-ignore (-C) and
- sending files to an older rsync without using --delete.
+ - If a non-directory is in the way of a directory and rsync is run with
+ --dry-run and --delete, rsync no longer complains about not being able
+ to opendir() the not-yet present directory.
+
+ - When --list-only is used and a non-existent local destination dir was
+ also specified as a destination, rsync no longer generates a warning
+ about being unable to create the missing directory.
+
+ - Fixed some problems with --relative --no-implied-dirs when the
+ destination directory did not yet exist: we can now create a symlink or
+ device when it is the first thing in the missing dir, and --fuzzy no
+ longer complains about being unable to open the missing dir.
+
+ - Got rid of the need for --force to be used in some circumstances with
+ --delete-after (making it consistent with --delete-before/-during).
+
+ - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this
+ when a file is too large (rsync handles the write error).
ENHANCEMENTS:
- - 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).
+ - Added the --append option that makes rsync append data onto files that
+ are longer on the source than the destination (this includes new files).
+
+ - Added the --min-size=SIZE option to exclude small files from the
+ transfer.
+
+ - Added the --compress-level option to allow you to set how aggressive
+ rsync's compression should be (this option implies --compress).
+
+ - 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 the --8-bit-output (-8) option, which tells rsync to avoid escaping
+ high-bit characters that it thinks are unreadable in the current locale.
+
+ - The new option --human-readable (-h) changes the output of --progress,
+ --stats, and the end-of-run summary to be easier to read. If repeated,
+ the units become powers of 1024 instead of powers of 1000. (The old
+ meaning of -h, as a shorthand for --help, still works as long as you
+ just use it on its own, as in "rsync -h".)
+
+ - If lutimes() and/or lchmod() are around, use them to allow the
+ preservation of attributes on symlinks.
+
+ - The --link-dest option now affects symlinks and devices (when possible).
+
+ - 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 man page 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
+
+ - Added the "incoming chmod" and "outgoing chmod" daemon options that allow
+ a module to specify what permissions changes should be applied to all
+ files copied to and from the daemon.
+
+ - 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 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.
+ - 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.
- - 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.)
+ - 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.
- - 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).
+ - The include/exclude code now allows a dir/*** directive (with 3 trailing
+ stars) to match both the dir itself as well as all the content below the
+ dir (dir/** would not match the dir).
- - 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).
+ - Added the --prune-empty-dirs (-m) option that makes the receiving rsync
+ discard empty chains of directories from the file-list. This makes it
+ easier to selectively copy files from a source hierarchy and end up with
+ just the directories needed to hold the resulting files.
+
+ - If the --itemize-changes (-i) option is repeated, rsync now includes
+ unchanged files in the itemized output (similar to -vv, but without all
+ the other verbose messages that can get in the way). Of course, the
+ client must be version 2.6.7 for this to work, but the remote rsync only
+ needs to be 2.6.7 if you're pushing files.
+
+ - Added the --specials option to tell rsync to copy non-device special
+ files (which rsync now attempts even as a normal user). The --devices
+ option now requests the copying of just devices (character and block).
+ The -D option still requests both (e.g. --devices and --specials), -a
+ still implies -D, and non-root users still get a silent downgrade that
+ omits device copying.
+
+ - Added the --super option to make the receiver always attempt super-user
+ activities. This is useful for systems that allow things such as devices
+ to be created or ownership to be set without being UID 0, and is also
+ useful for someone who wants to ensure that errors will be output if the
+ receiving rsync isn't being run as root.
+
+ - Added the --sockopts option for those few who want to customize the TCP
+ options used to contact a daemon rsync.
+
+ - Added a way for the --temp-dir option to be combined with a partial-dir
+ setting that lets rsync avoid non-atomic updates (for those times when
+ --temp-dir is not being used because space is tight).
+
+ - A new support script, files-to-excludes, will transform a list of files
+ into a set of include/exclude directives that will copy those files.
+
+ - A new option, --executability (-E) can be used to preserve just the
+ execute bit on files, for those times when using the --perms option is
+ not desired.
+
+ - The daemon now logs each connection and also each module-list request
+ that it receives.
+
+ - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
+ (permission bits, e.g. "rwxr-xrwt").
+
+ - The --dry-run option no longer forces the enabling of --verbose.
+
+ - The --remove-sent-files option now does a better job of incrementally
+ removing the sent files on the sending side (older versions tended to
+ clump up all the removals at the end).
+
+ - A daemon now supersedes its minimal SIGCHLD handler with the standard
+ PID-remembering version after forking to handle the request. This
+ ensures that the generator can get the child-exit status from the
+ receiver.
+
+ - Use of the --bwlimit option no longer interferes with the remote rsync
+ sending error messages about invalid/refused options.
+
+ - Rsync no longer returns a usage error when used with one local source arg
+ and no destination: this now implies the --list-only option, just like
+ the comparable situation with a remote source arg.
+
+ - Various documentation improvements, including: a better synopsis, some
+ improved examples, a better discussion of the presence and absence of
+ --perms (including how it interacts with the new --executability and
+ --chmod options), an extended discussion of --temp-dir, an improved
+ discussion of --partial-dir, a better description of rsync's pattern
+ matching characters, and the documenting of what the various items in
+ the --stats output mean.
+
+ - Various new and updated diffs in the patches dir, including: acls.diff,
+ xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
INTERNAL:
- - Rsync now calls setlocale(LC_CTYPE, "").
+ - We now use sigaction() and sigprocmask() if possible, and fall back on
+ signal() if not. Using sigprocmask() ensures that rsync enables all the
+ signals that it needs, just in case it was started in a masked state.
+
+ - 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.
+
+ - The wildmatch function was extended to allow an array of strings to be
+ supplied as the string to match. This allows the exclude code to do less
+ string copying.
+
+ - Got rid of the safe_fname() function (and all the myriad calls) and
+ replaced it with a new function in the log.c code that filters all the
+ output going to the terminal.
+
+ - Unified the f_name() and the f_name_to() functions.
- BUILD CHANGES:
+ DEVELOPER RELATED:
- - Fixed a bug in the SUPPORT{,_HARD}_LINKS defines which prevented
- rsync from being built without symlink or hard-link support.
+ - The diffs in the patches dir now require "patch -p1 <DIFF" instead of
+ the previous -p0. Also, the version included in the release tar now
+ affect generated files (e.g. configure, rsync.1, proto.h, etc.), so
+ it is no longer necessary to run autoconf and/or yodl unless you're
+ applying a patch that was checked out from CVS.
- - You can use --disable-locale to turn off any use of setlocale().
+ - 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.
- - Configure now disables the use of mkstemp() under HP-UX (since they
- refuse to fix its broken handling of large files).
+ - There is a new script, "prepare-source" than can be used to update the
+ various generated files (proto.h, configure, etc.) even before configure
+ has created the Makefile (this is mainly useful when patching the source
+ with a patch that doesn't affect generated 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.
+ - The testsuite now sets HOME so that it won't be affected by a file such
+ as ~/.popt.
