-NEWS for rsync version 2.6.0
-Protocol: 27 (changed)
-Changes since version 2.5.7:
+NEWS for rsync 2.6.4 (UNRELEASED)
+Protocol: 29 (changed)
+Changes since 2.6.3:
- ENHANCEMENTS:
-
- * 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)
-
- * Length of csum2 is now per-file starting with protocol verison
- 27. (J.W. Schultz)
-
- * 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)
-
- * The --stats option no longer includes the (debug) malloc summary
- unless the verbose option was specified at least twice.
-
- * 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.
-
- BUG FIXES:
-
- * 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)
-
- - A pattern with a "**" no longer causes a "*" to match slashes.
- For example, with "/*/foo/**", "foo" must be 2 levels deep.
-
- - "**/foo" now matches at the base of the transfer (i.e. /foo).
+ OUTPUT CHANGES:
- - An 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.
+ - 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.
- - 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" (for instance).
-
- * 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)
-
- * 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)
+ - 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).
- * 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)
-
- * 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)
-
- * Keep tmp names from overflowing MAXPATHLEN.
-
- * Make --link-dest honor the absence of -p, -o, and -g.
-
- * Made rsync treat a trailing slash in the destination in a more
- consistent manner.
-
- * Fixed file I/O error detection. (John Van Essen)
-
- * Fixed a compression (-z) bug when syncing a mostly-matching file
- that contains already-compressed data. (Yasuoka Masahiko and
- Wayne Davison)
-
- * Fixed a bug in the --backup code that could cause deleted files
- to not get backed up.
+ BUG FIXES:
- * Call setgroups() in a more portable manner.
+ - 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).
- * Improved file-related error messages to better indicate exactly
- what pathname failed. (Wayne Davison)
+ - The --dry-run option (-n) now mentions changes in directories (w/-v).
+ It also now includes the normal uptodate output information for -vv.
- * Fixed some bugs in the handling of --delete and --exclude when
- using the --relative (-R) option. (Wayne Davison)
+ - Avoid a mkdir warning when removing a directory in the destination
+ that already exists in the --backup-dir.
- * 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)
+ - An OS that has a binary mode for its files (such as cygwin0 needed
+ setmode(fd, O_BINARY) called on the temp-file we opened with
+ mkstemp(). (Fix derived from the cygwin's rsync package.)
- * Detect and report when open or opendir succeed but read and
- readdir fail caused by network filesystems issues and truncated
- files. (David Norwood, Michael Brown, J.W. Schultz)
+ - Fixed a potential hang when verbosity is high, the client side is
+ the sender, and the file-list is large.
- INTERNAL:
+ - 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.
- * Eliminated vestigial support for old versions that we stopped
- supporting. (J.W. Schultz)
+ - Fixed an off-by-one error in the handling of --max-delete=N.
- * Simplified some of the option-parsing code. (Wayne Davison)
+ - One place in the code wasn't checking if fork() failed.
- * Some cleanup made to the exclude code, as well as some new
- defines added to enhance readability. (Wayne Davison)
+ - The "ignore nonreadable" daemon parameter no longer affects symlinks
+ that are being copied, even if they point nowhere.
- * 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)
+ - If the OS does not have lchown() and its chown() tries to set the
+ referent of a symlink (as it should), we no longer try to set the
+ user and group of a symlink.
+ - 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.
-NEWS for rsync version 2.5.7:
-Protocol: 26 (unchanged)
-Changes since version 2.5.6:
+ - 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.
- SECURITY:
+ - One call to flush_write_file() was not being checked for an error.
- * Fix buffer handling bugs. (Andrew Tridgell, Martin Pool, Paul
- Russell, Andrea Barisani)
+ - 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 (i.e. rsync might have
+ exited with an error for large files).
-NEWS for rsync version 2.5.6, aka the dwd-between-jobs release
-Protocol: 26 (unchanged)
-Changes since version 2.5.5:
+ - If a daemon can't open the specified log file (i.e. syslog is not
+ being used), die without crashing. We also try to output an error
+ about the failure (which will only be seen if --no-detach was
+ specified).
ENHANCEMENTS:
- * The --delete-after option now implies --delete. (Wayne Davison)
+ - 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 (which makes it more efficient than the
+ default, before-the-transfer behavior of --delete). Note that the
+ --del option is implemented as an internally-defined popt alias, so
+ an rsync daemon that refuses "delete" (which, for safety's sake,
+ really matches "delete*") will still refuse all delete options. The
+ default behavior is also explicitly selectable via --delete-before.
+
+ - 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 (such as a hang or an abort) when a client connects.
+
+ - 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".
+
+ - 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.
+
+ - 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
+ option kluges (e.g. the age-old use of "-r --exclude="/*/*" for a
+ non-recursive listing). This option is used automatically 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.
+
+ - 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.
+
+ - 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.)
+
+ SUPPORT FILES:
+
+ - Added support/atomic-rsync -- 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 support/mnt-excl 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 support/savetransfer.c -- 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 support/rrsync -- 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.
+
+ - Improved the option descriptions in the --help text.
- * The --suffix option can now be used with --backup-dir. (Michael
- Zimmerman)
-
- * 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)
-
- * The rsync:// syntax for daemon connections is now accepted in the
- destination field.
-
- * If the file name given to --include-from or --exclude-from is "-",
- rsync will read from standard input. (J.W. Schultz)
-
- * New option --link-dest which is like --compare-dest except that
- unchanged files are hard-linked in to the destination directory.
- (J.W. Schultz)
-
- * Don't report an error if an excluded file disappears during an
- rsync run. (Eugene Chupriyanov and Bo Kersey)
-
- * Added .svn to --cvs-exclude list to support subversion. (Jon
- Middleton)
-
- * Properly support IPv6 addresses in the rsyncd.conf "hosts allow"
- and "hosts deny" fields. (Hideaki Yoshifuji)
-
- * Changed exclude file handling to permit DOS or MAC style line
- terminations. (J.W. Schultz)
-
- * Ignore errors from chmod when -p/-a/--preserve-perms is not set.
- (Dave Dykstra)
-
- BUG FIXES:
-
- * Fix "forward name lookup failed" errors on AIX 4.3.3. (John
- L. Allen, Martin Pool)
-
- * 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)
-
- * Fix compilation on Tru64. (Albert Chin, Zoong Pham)
-
- * Better handling of some client-server errors. (Martin Pool)
-
- * 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)
-
- * Fixed the file-name duplicate-removal code when dealing with multiple
- dups in a row. (Wayne Davison)
-
- * 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)
-
- * Fixed bug in --copy-unsafe-links that caused it to be completely
- broken. (Dave Dykstra)
-
- * Prevent infinite recursion in cleanup code under certain circumstances.
- (Sviatoslav Sviridov and Marc Espie)
+ INTERNAL:
- * Fixed a bug that prevented rsync from creating intervening directories
- when --relative-paths/-R is set. (Craig Barratt)
+ - Added better checking of the checksum-header values that come over
+ the socket.
- * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara)
+ - Merged the various delete-file functions into a single function so
+ that it is easier to maintain.
- INTERNAL:
+ - Improved the type of some variables (particularly blocksize vars) for
+ consistency and proper size.
- * Many code cleanups and improved internal documentation. (Martin
- Pool, Nelson Beebe)
+ - Got rid of the uint64 type (which we didn't need).
- * Portability fixes. (Dave Dykstra and Wayne Davison)
+ - Use a slightly more compatible set of core #include directives.
- * More test cases. (Martin Pool)
+ - Defined int32 in a way that ensures that the build dies if we can't
+ find a variable with at least 32 bits.
- * Some test-case fixes. (Brian Poole, Wayne Davison)
+ BUILD CHANGES:
- * Updated included popt to the latest vendor drop, version 1.6.4.
- (Jos Backus)
+ - Handle an operating system that use mkdev() in place of makedev().
- * Updated config.guess and config.sub to latest versions; this
- means rsync should build on more platforms. (Paul Green)
+ - Improved configure to better handle cross-compiling.
