+NEWS for rsync 2.6.7 (UNRELEASED)
+Protocol: 29 (unchanged)
+Changes since 2.6.6:
+
+ OUTPUT CHANGES:
+
+ - 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.
- ENHANCEMENTS:
+ BUG FIXES:
- * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
- Note that --from0 affects the line-ending character for all the
- --*-from options. (Wayne Davison)
+ - Fixed a really old bug that caused --checksum (-c) to checksum all the
+ files encountered during the delete scan (ouch).
- * Length of csum2 is now per-file starting with protocol verison
- 27. (J.W. Schultz)
+ - 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).
- * Per-file dynamic block size is now sqrt(file length).
- The per-file checksum size is determined according
- to an algorythm provided by Donovan Baarda which
- reduces the probability of rsync algorithm
- corrupting data and falling back using the whole md4
- checksums. (J.W. Schultz, Donovan Baarda)
+ - Made hard-links work with symlinks and devices again.
- * The --stats option no longer includes the (debug) malloc summary
- unless the verbose option was specified at least twice.
+ - 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).
- BUG FIXES:
+ - If a device-file/special-file changes permissions, rsync now updates the
+ permissions without recreating the file.
- * For protocol version >= 27, mdfour_tail() is called when the
- block size (including checksum_seed) is a multiple of 64.
- Previously it was not called, giving the wrong MD4 checksum.
- (Craig Barratt)
-
- * For protocol version >= 27, a 64 bit bit counter is used in
- mdfour.c as required by the RFC. Previously only a 32 bit bit
- counter was used, causing incorrect MD4 file checksums for
- file sizes >= 512MB - 4. (Craig Barratt)
+ - 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 crash bug when interacting with older rsync versions and
- multiple files of the same name are destined for the same dir.
- (Wayne Davison)
+ - 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.
- * Keep tmp names from overflowing MAXPATHLEN.
+ - Reject the combination of --inplace and --sparse since the sparse-output
+ algorithm doesn't work when overwriting existing data.
- * Make --link-dest honor the absence of -p, -o, and -g.
+ - Fixed the directory name in the error that is output when pop_dir()
+ fails.
- * Made rsync treat a trailing slash in the destination in a more
- consistent manner.
+ - Really fixed the parsing of a "!" entry in .cvsignore files this time.
- * Fixed some exclude/include matching bugs when using wild-cards.
- For instance, "**/foo" now matches at the root, "CVS/R*" now
- matches beyond the root, and "foo**bar" is matched against the
- path, not just the trailing name. (Wayne Davison)
+ - 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).
+ - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
+ the exit status properly and generate a better error.
- INTERNAL:
+ - 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 the matching of the dont-compress items (e.g. *.gz) against files
+ that have a path component containing a slash.
+
+ - 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.
+
+ - 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.
- * Eliminated vestigial support for old versions that we stopped
- supporting. (J.W. Schultz)
+ - 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.
- * Simplified some of the option-parsing code. (Wayne Davison)
+ - 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.
-NEWS for rsync version 2.5.6, aka the dwd-between-jobs release
-Protocol: 26 (unchanged)
-Changes since version 2.5.5:
+ - Fixed a bug where the --copy-links option would not affect implied
+ directories without --copy-unsafe-links (see --relative).
+
+ - 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).
+
+ - Fixed a bug in the debug output (-vvvvv) that could mention the wrong
+ checksum for the current file offset.
+
+ - Rsync no longer allows a single directory to be copied over a non-
+ directory destination arg.
ENHANCEMENTS:
- * The --delete-after option now implies --delete. (Wayne Davison)
+ - 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.
- * The --suffix option can now be used with --backup-dir. (Michael
- Zimmerman)
+ - 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).
- * Combining "::" syntax with the -rsh/-e option now uses the
- specified remote-shell as a transport to talk to a (newly-spawned)
- server-daemon. This allows someone to use daemon features, such
- as modules, over a secure protocol, such as ssh. (JD Paul)
+ - 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 rsync:// syntax for daemon connections is now accepted in the
- destination field.
+ - 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 the file name given to --include-from or --exclude-from is "-",
- rsync will read from standard input. (J.W. Schultz)
+ - If lutimes() and/or lchmod() are around, use them to allow the
+ preservation of attributes on symlinks.
- * New option --link-dest which is like --compare-dest except that
- unchanged files are hard-linked in to the destination directory.
- (J.W. Schultz)
+ - The --link-dest option now affects symlinks and devices (when possible).
- * Don't report an error if an excluded file disappears during an
- rsync run. (Eugene Chupriyanov and Bo Kersey)
+ - 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.)
- * Added .svn to --cvs-exclude list to support subversion. (Jon
- Middleton)
+ - 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).
- * Properly support IPv6 addresses in the rsyncd.conf "hosts allow"
- and "hosts deny" fields. (Hideaki Yoshifuji)
+ - 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.
- * Changed exclude file handling to permit DOS or MAC style line
- terminations. (J.W. Schultz)
+ - Added the --chmod=MODE option that allows the destination permissions to
+ be changed from the source permissions. E.g. --chmod=g+w,o-rwx
- * Ignore errors from chmod when -p/-a/--preserve-perms is not set.
- (Dave Dykstra)
+ - 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.
- BUG FIXES:
+ - 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.
- * Fix "forward name lookup failed" errors on AIX 4.3.3. (John
- L. Allen, Martin Pool)
+ - 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.
- * Generate each file's rolling-checksum data as we send it, not
- in a separate (memory-eating) pass before hand. This prevents
- timeout errors on really large files. (Stefan Nehlsen)
+ - 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.
- * Fix compilation on Tru64. (Albert Chin, Zoong Pham)
+ - 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).
- * Better handling of some client-server errors. (Martin Pool)
+ - 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.
- * Fixed a crash that would occur when sending a list of files that
- contains a duplicate name (if it sorts to the end of the file
- list) and using --delete. (Wayne Davison)
+ - 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.
- * Fixed the file-name duplicate-removal code when dealing with multiple
- dups in a row. (Wayne Davison)
+ - 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.
- * Fixed a bug that caused rsync to lose the exit status of its child
- processes and sometimes return an exit code of 0 instead of showing
- an error. (David R. Staples, Dave Dykstra)
+ - 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.
- * Fixed bug in --copy-unsafe-links that caused it to be completely
- broken. (Dave Dykstra)
+ - Added the --sockopts option for those few who want to customize the TCP
+ options used to contact a daemon rsync.
- * Prevent infinite recursion in cleanup code under certain circumstances.
- (Sviatoslav Sviridov and Marc Espie)
+ - 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).
- * Fixed a bug that prevented rsync from creating intervening directories
- when --relative-paths/-R is set. (Craig Barratt)
+ - 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.
- * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara)
+ - 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. 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.
+
+ - Added the --copy-dirlinks option, a more limited version of --copy-links.
+
+ - 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, an improved --no-implied-dirs section, and the
+ documenting of what the --stats option outputs.
+
+ - Various new and updated diffs in the patches dir, including: acls.diff,
+ xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
INTERNAL:
- * Many code cleanups and improved internal documentation. (Martin
- Pool, Nelson Beebe)
+ - 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.
+
+ - Improved the hash-table code the sender uses to handle checksums to make
+ it use slightly less memory and run just a little faster.
- * Portability fixes. (Dave Dykstra and Wayne Davison)
+ DEVELOPER RELATED:
- * More test cases. (Martin Pool)
+ - 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.
- * Some test-case fixes. (Brian Poole, Wayne Davison)
+ - 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.
- * Updated included popt to the latest vendor drop, version 1.6.4.
- (Jos Backus)
+ - 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).
- * Updated config.guess and config.sub to latest versions; this
- means rsync should build on more platforms. (Paul Green)
+ - The testsuite now sets HOME so that it won't be affected by a file such
+ as ~/.popt.
