+NEWS for rsync 2.6.7 (UNRELEASED)
+Protocol: 29 (unchanged)
+Changes since 2.6.6:
+
+ OUTPUT CHANGES:
+
+ - The itemized output now uses 'S' for a special file instead of
+ clumping them together with the 'D' for devices. The number of
+ characters is also different (to remove an unused field).
+
+ - 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 (-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:
- * The RSYNC_PROXY environment variable can now contain a
- "USER:PASS@" prefix before the "HOST:PORT" information.
- (Bardur Arantsson)
+ - Fixed a really old bug that caused --checksum (-c) to checksum all the
+ files encountered during the delete scan (ouch).
- BUG FIXES:
+ - 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).
- * The --link-dest code now works properly for a non-root user
- when the UIDs of the source and destination differ and -u was
- specified, and when the group of the source can't be used on
- the destination and -g was specified. (Wayne Davison)
-
- * 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).
- (Wayne Davison)
-
- * Keep per-file track of the sending of literal data with
- --partial so that an interrupted transfer doesn't keep a
- shorter temp file when no new data has been transfered over
- the wire.
+ - Made hard-links work with symlinks and devices again.
- INTERNAL:
+ - 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).
- * Most of the I/O is now buffered, which results in a pretty
- large speedup when running under MS Windows. (Craig Barratt)
+ - If a device-file/special-file changes permissions, rsync now updates the
+ permissions without recreating the file.
- * Optimizations to the name-handling/comparing code have made
- some significant reductions in user CPU time for large file
- sets. (Wayne Davison)
+ - 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.
- * Some variable-type cleanup that makes the code more consistent.
- (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.

-NEWS for rsync 2.6.0 (1 Jan 2004)
-Protocol: 27 (changed)
-Changes since 2.5.7:
+ - Reject the combination of --inplace and --sparse since the sparse-output
+ algorithm doesn't work when overwriting existing data.
- ENHANCEMENTS:
+ - Fixed the directory name in the error that is output when pop_dir()
+ fails.
- * "ssh" is now the default remote shell for rsync. If you want to
- change this, configure like this: "./configure --with-rsh=rsh".
+ - Really fixed the parsing of a "!" entry in .cvsignore files this time.
- * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
- Note that --from0 affects the line-ending character for all the
- files read by the --*-from options. (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).
- * Length of csum2 is now per-file starting with protocol version
- 27. (J.W. Schultz)
+ - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
+ the exit status properly and generate a better error.
- * Per-file dynamic block size is now sqrt(file length). The
- per-file checksum size is determined according to an algorithm
- 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)
+ - Fixed some glitches in the double-verbose output when using --copy-dest,
+ --link-dest, or --compare-dest.
- * The --stats option no longer includes the (debug) malloc summary
- unless the verbose option was specified at least twice.
+ - Fixed the matching of the dont-compress items (e.g. *.gz) against files
+ that have a path component containing a slash.
- * Added a new error/warning code for when files vanish from the
- sending side. Made vanished source files not interfere with the
- file-deletion pass when --delete-after was specified.
+ - 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.
- * Various trailing-info sections are now preceded by a newline.
+ - 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.
- BUG FIXES:
+ - 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.
+
+ - Got rid of the need for --force to be used in some circumstances with
+ --delete-after (making it consistent with --delete-before/-during).
+
+ ENHANCEMENTS:
+
+ - Added the --specials option to tell rsync to copy special files (and does
+ not require root). The --devices option now affects just character and
+ block devices (which now matches the documentation). The -D option still
+ requests both --devices and --specials, and -a still implies -D.
+
+ - 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).
- * Fixed several exclude/include matching bugs when using wild-cards.
- This has a several user-visible effects, all of which make the
- matching more consistent and intuitive. This should hopefully not
- cause anyone problems since it makes the matching work more like
- what people are expecting. (Wayne Davison)
+ - 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).
- - A pattern with a "**" no longer causes a "*" to match slashes.
- For example, with "/*/foo/**", "foo" must be 2 levels deep.
- [If your string has BOTH "*" and "**" wildcards, changing the
- "*" wildcards to "**" will provide the old behavior in all
- versions.]
+ - Added the --8-bit (-8) option, which tells rsync to avoid escaping high-
+ bit characters that it thinks are unreadable in the current locale.
- - "**/foo" now matches at the base of the transfer (like /foo
- does). [Use "/**/foo" to get the old behavior in all versions.]
+ - The new options --human-readable (-h) and --si change the output of the
+ --stats and the end-of-run summary to be easier to read.
- - A non-anchored wildcard term floats to match beyond the base of
- the transfer. E.g. "CVS/R*" matches at the end of the path,
- just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
- to get the old behavior in all versions.]
+ - If lutimes() and/or lchmod() are around, use them to allow the
+ preservation of attributes on symlinks.
- - Including a "**" in the match term causes it to be matched
- against the entire path, not just the name portion, even if
- there aren't any interior slashes in the term. E.g. "foo**bar"
- would exclude "/path/foo-bar" (just like before) as well as
- "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
- old behavior in all versions.]
+ - The --link-dest option now affects symlinks and devices (when possible).
- * The exclude list specified in the daemon's config file is now
- properly applied to the pulled items no matter how deep the
- user's file-args are in the source tree. (Wayne Davison)
+ - Improved the output of hard-linked and copied files when using
+ --link-dest, --copy-dest, or --compare-dest.
- * 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)
+ - 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 manpage for a list of the environment variables that are set with
+ information about the transfer.)
- * 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)
+ - 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).
- * 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)
+ - 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.
- * Keep tmp names from overflowing MAXPATHLEN.
+ - Added the --chmod=MODE option that allows the destination permissions to
+ be changed from the source permissions. E.g. --chmod=g+w,o-rwx
- * Make --link-dest honor the absence of -p, -o, and -g.
+ - 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.
- * Made rsync treat a trailing slash in the destination in a more
- consistent manner.
+ - Allow the --temp-dir option to be specified when starting a daemon, which
+ sets the default temporary directory for incoming files.
- * Fixed file I/O error detection. (John Van Essen)
+ - If --delete is combined with --dirs without --recursive, rsync will now
+ delete in any directory whose content is being synchronized.
- * Fixed bogus "malformed address {hostname}" message in rsyncd log
- when checking IP address against hostnames from "hosts allow"
- and "hosts deny" parameters in config file.
+ - 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.
- * Print heap statistics when verbose >= 2 instead of when >= 1.
+ - 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.
- * Fixed a compression (-z) bug when syncing a mostly-matching file
- that contains already-compressed data. (Yasuoka Masahiko and
- Wayne Davison)
+ - 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).
- * Fixed a bug in the --backup code that could cause deleted files
- to not get backed up.
+ - 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.
- * When the backup code makes new directories, create them with mode
- 0700 instead of 0755 (since the directory permissions in the
- backup tree are not yet copied from the main tree).
+ - 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.
- * Call setgroups() in a more portable manner.
+ - 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.
- * Improved file-related error messages to better indicate exactly
- what pathname failed. (Wayne Davison)
+ - Added the --sockopts option for those few who want to customize the TCP
+ options used to contact a daemon rsync.
- * Fixed some bugs in the handling of --delete and --exclude when
- using the --relative (-R) option. (Wayne Davison)
+ - 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 bug that prevented regular files from replacing
- special files and caused a directory in --link-dest or
- --compare-dest to block the creation of a file with the
- same path. A directory still cannot be replaced by a
- regular file unless --delete specified. (J.W. Schultz)
+ - 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.
- * Detect and report when open or opendir succeed but read and
- readdir fail caused by network filesystem issues and truncated
- files. (David Norwood, Michael Brown, J.W. Schultz)
+ - 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.
- * Added a fix that should give ssh time to restore the tty settings
- if the user presses Ctrl-C at an ssh password prompt.
+ - The daemon now logs each module-list request it receives.
+
+ - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
+ (permission bits, e.g. "rwxr-xrwt").
+
+ - Some minor documentation improvements.
+
+ - Updated some diffs in the patches dir.
INTERNAL:
- * Eliminated vestigial support for old versions that we stopped
- supporting. (J.W. Schultz)
+ - 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.
+
+ DEVELOPER RELATED:
+
+ - 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.
- * Simplified some of the option-parsing code. (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.
- * Some cleanup made to the exclude code, as well as some new
- defines added to enhance readability. (Wayne Davison)
+ - 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).
- * Changed the protocol-version code so that it can interact at a
- lower protocol level than the maximum supported by both sides.
- Added an undocumented option, --protocol=N, to force the value
- we advertise to the other side (primarily for testing purposes).
- (Wayne Davison)
+ - The testsuite now sets HOME so that it won't be affected by a file such
+ as ~/.popt.
