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. - * 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) + - 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. - - A pattern with a "**" no longer causes a "*" to match slashes. - For example, with "/*/foo/**", "foo" must be 2 levels deep. + - 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. - - "**/foo" now matches at the base of the transfer (i.e. /foo). + - Reject the combination of --inplace and --sparse since the sparse-output + algorithm doesn't work when overwriting existing data. - - 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. + - Fixed the directory name in the error that is output when pop_dir() + fails. - - 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). + - Really fixed the parsing of a "!" entry in .cvsignore files this time. - * 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) + - 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). - * 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 waitpid() fails or the child rsync didn't exit cleanly, we now handle + the exit status properly and generate a better error. - * 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) + - 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). - * Keep tmp names from overflowing MAXPATHLEN. + - Fixed the matching of the dont-compress items (e.g. *.gz) against files + that have a path component containing a slash. - * Make --link-dest honor the absence of -p, -o, and -g. + - 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. - * Made rsync treat a trailing slash in the destination in a more - consistent manner. + - 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 file I/O error detection. (John Van Essen) + - 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. - * Fixed a compression (-z) bug when syncing a mostly-matching file - that contains already-compressed data. (Yasuoka Masahiko and - 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 a bug in the --backup code that could cause deleted files - to not get backed up. + - 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. - * Call setgroups() in a more portable manner. + - Fixed a bug where the --copy-links option would not affect implied + directories without --copy-unsafe-links (see --relative). - * Improved file-related error messages to better indicate exactly - what pathname failed. (Wayne Davison) + - Got rid of the need for --force to be used in some circumstances with + --delete-after (making it consistent with --delete-before/-during). - * Fixed some bugs in the handling of --delete and --exclude when - using the --relative (-R) option. (Wayne Davison) + - 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 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) + - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it + was not properly padded with trailing '=' chars. This only affects a + user that need to use a password-authenticated proxy for an outgoing + daemon-rsync connection. - * 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 bug in the debug output (-vvvvv) that could mention the wrong + checksum for the current file offset. - INTERNAL: + - Rsync no longer allows a single directory to be copied over a non- + directory destination arg. - * Eliminated vestigial support for old versions that we stopped - supporting. (J.W. Schultz) + ENHANCEMENTS: - * Simplified some of the option-parsing code. (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. - * Some cleanup made to the exclude code, as well as some new - defines added to enhance readability. (Wayne Davison) + - 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). - * 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) + - 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".) -NEWS for rsync version 2.5.6, aka the dwd-between-jobs release -Protocol: 26 (unchanged) -Changes since version 2.5.5: + - If lutimes() and/or lchmod() are around, use them to allow the + preservation of attributes on symlinks. - ENHANCEMENTS: + - The --link-dest option now affects symlinks and devices (when possible). - * The --delete-after option now implies --delete. (Wayne Davison) + - 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.) - * The --suffix option can now be used with --backup-dir. (Michael - Zimmerman) + - 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). - * 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 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. - * The rsync:// syntax for daemon connections is now accepted in the - destination field. + - Added the --chmod=MODE option that allows the destination permissions to + be changed from the source permissions. E.g. --chmod=g+w,o-rwx - * If the file name given to --include-from or --exclude-from is "-", - rsync will read from standard input. (J.W. Schultz) + - 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. - * New option --link-dest which is like --compare-dest except that - unchanged files are hard-linked in to the destination directory. - (J.W. Schultz) + - Allow the --temp-dir option to be specified when starting a daemon, which + sets the default temporary directory for incoming files. - * Don't report an error if an excluded file disappears during an - rsync run. (Eugene Chupriyanov and Bo Kersey) + - If --delete is combined with --dirs without --recursive, rsync will now + delete in any directory whose content is being synchronized. - * Added .svn to --cvs-exclude list to support subversion. (Jon - Middleton) + - 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. - * Properly support IPv6 addresses in the rsyncd.conf "hosts allow" - and "hosts deny" fields. (Hideaki Yoshifuji) + - 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. - * Changed exclude file handling to permit DOS or MAC style line - terminations. (J.W. Schultz) + - 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). - * Ignore errors from chmod when -p/-a/--preserve-perms is not set. - (Dave Dykstra) + - 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. - BUG FIXES: + - 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. - * Fix "forward name lookup failed" errors on AIX 4.3.3. (John - L. Allen, Martin Pool) + - 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. - * 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) + - 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. - * Fix compilation on Tru64. (Albert Chin, Zoong Pham) + - Added the --sockopts option for those few who want to customize the TCP + options used to contact a daemon rsync. - * Better handling of some client-server errors. (Martin Pool) + - 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 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) + - 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. - * Fixed the file-name duplicate-removal code when dealing with multiple - dups in a row. (Wayne Davison) + - 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. - * 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) + - New log-format options: %M (modtime), %U (uid), %G (gid), and %B + (permission bits, e.g. "rwxr-xrwt"). - * Fixed bug in --copy-unsafe-links that caused it to be completely - broken. (Dave Dykstra) + - 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). - * Prevent infinite recursion in cleanup code under certain circumstances. - (Sviatoslav Sviridov and Marc Espie) + - 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. - * Fixed a bug that prevented rsync from creating intervening directories - when --relative-paths/-R is set. (Craig Barratt) + - 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. - * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara) + - 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
