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: - - Fixed a crash bug that might appear when --delete was used and - multiple source directories were specified. + - Fixed a really old bug that caused --checksum (-c) to checksum all the + files encountered during the delete scan (ouch). - - The --backup code no longer attempts to create some directories - over and over again (generating warnings along the way). + - 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). - - Fixed a bug in the reading of the secrets file (by the daemon) and - the password file (by the client): the files no longer need to be - terminated by a newline for their content to be read in. + - Made hard-links work with symlinks and devices again. - - If a file has a read error on the sending side, the receiver will - no longer keep the resulting file unless the --partial option was - specified. (Note: both sides must be running 2.6.3 for this to - work -- older receivers always keep the file, and older senders - don't tell the receiver that the file was not read correctly.) + - 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). - - Fixed an age-old crash problem with --read-batch on a local copy - (rsync was improperly assuming --whole-file for the local copy). + - If a device-file/special-file changes permissions, rsync now updates the + permissions without recreating the file. - - Files specified in the daemon's "exclude" or "exclude from" config - items are now excluded from being uploaded (if the module is not - read-only) in addition to the old download exclusion. + - 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. - - When using --backup without a --backup-dir, rsync no longer preserves - the modify time on directories. This avoids confusing NFS. + - 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. - - Fixed a bug in the daemon authentication code when using one of the - batch-processing options. + - 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. - - Added the "write only" option to the daemon's config file. + - Really fixed the parsing of a "!" entry in .cvsignore files this time. - - Added the --checksum-seed=N option for advanced users. + - 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). - - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) - and documented all these options in the man page. + - If waitpid() fails or the child rsync didn't exit cleanly, we now handle + the exit status properly and generate a better error. - - Improved the handling of the --bwlimit option so that it's less - bursty, more accurate, and works properly over a larger range of - values. + - 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). - INTERNAL: + - Fixed the matching of the dont-compress items (e.g. *.gz) against files + that have a path component containing a slash. - - Some cleanup in the exclude code has saved some per-exclude memory - and made the code easier to maintain. + - 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. - - Use rsyserr() in the various places that were still calling - rprintf() with strerror() as an arg. + - 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. - BUILD CHANGES: + - 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. - - Added a "gen" target to rebuild most of the various generated - files, including configure, config.h.in, the man pages, and - proto.h. + - 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. - - The timestamp of the proto.h file is unaltered by "make proto" - if the contents don't change. + - 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. - DEVELOPER RELATED: + - Fixed a bug where the --copy-links option would not affect implied + directories without --copy-unsafe-links (see --relative). - - The scripts in the testsuite dir were cleaned up a bit. + - Got rid of the need for --force to be used in some circumstances with + --delete-after (making it consistent with --delete-before/-during). - -NEWS for rsync 2.6.2 (30 Apr 2004) -Protocol: 28 (unchanged) -Changes since 2.6.1: + - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this + when a file is too large (rsync handles the write error). - BUG FIXES: + - 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. - - Fixed a major bug in the sorting of the filenames when --relative - is used for some sources (just sources such as "/" and "/*" were - affected). This fix ensures that we ask for the right file-list - item when requesting changes from the sender. + - Fixed a bug in the debug output (-vvvvv) that could mention the wrong + checksum for the current file offset. - - Rsync now checks the return value of the close() function to - better report disk-full problems on an NFS file system. + - Rsync no longer allows a single directory to be copied over a non- + directory destination arg. - - Restored the old daemon-server behavior of logging error messages - rather than returning them to the user. (A better long-term fix - will be sought in the future.) + ENHANCEMENTS: - - An obscure uninitialized-variable bug was fixed in the uid/gid - code. (This bug probably had no ill effects.) + - 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. - BUILD CHANGES: + - 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). - - Got rid of the configure check for sys/sysctl.h (it wasn't used - and was causing a problem on some systems). Also improved the - broken-largefile-locking test to try to avoid failure due to an - NFS build-dir. + - 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. - - Fixed a compile problem on systems that don't define - AI_NUMERICHOST. + - 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".) - - Fixed a compile problem in the popt source for compilers that - don't support __attribute__. + - If lutimes() and/or lchmod() are around, use them to allow the + preservation of attributes on symlinks. - DEVELOPER RELATED: + - The --link-dest option now affects symlinks and devices (when possible). - - Improved the testsuite's "merge" test to work on OSF1. + - 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.) - - Two new diffs were added to the patches dir. + - 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). - -NEWS for rsync 2.6.1 (26 Apr 2004) -Protocol: 28 (changed) -Changes since 2.6.0: + - 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. - SECURITY FIXES: + - Added the --chmod=MODE option that allows the destination permissions to + be changed from the source permissions. E.g. --chmod=g+w,o-rwx - - Paths sent to an rsync daemon are more thoroughly sanitized when - chroot is not used. If you're running a non-read-only rsync - daemon with chroot disabled, *please upgrade*, ESPECIALLY if the - user privs you run rsync under is anything above "nobody". + - 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. - ENHANCEMENTS: + - Allow the --temp-dir option to be specified when starting a daemon, which + sets the default temporary directory for incoming files. - - Lower memory use, more optimal transfer of data over the socket, - and lower CPU usage (see the INTERNAL section for details). + - If --delete is combined with --dirs without --recursive, rsync will now + delete in any directory whose content is being synchronized. - - The RSYNC_PROXY environment variable can now contain a - "USER:PASS@" prefix before the "HOST:PORT" information. - (Bardur Arantsson) + - 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. - - The --progress output now mentions how far along in the transfer - we are, including both a count of files transferred and a - percentage of the total file-count that we've processed. It also - shows better current-rate-of-transfer and remaining-transfer-time - values. + - 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. - - Documentation changes now attempt to describe some often mis- - understood features more clearly. + - 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). - BUG FIXES: - - - When -x (--one-file-system) is combined with -L (--copy-links) or - --copy-unsafe-links, no symlinked files are skipped, even if the - referent file is on a different filesystem. - - - The --link-dest code now works properly for a non-root user when - (1) the UIDs of the source and destination differ and -o was - specified, or (2) when the group of the source can't be used on - the destination and -g was specified. - - - 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). - - - We now reset the "new data has been sent" flag at the start of - each file we send. This makes sure that an interrupted transfer - with the --partial option set doesn't keep a shorter temp file - than the current basis file when no new data has been transfered - over the wire for that file. - - - Fixed a byte-order problem in --batch-mode on big-endian machines. - (Jay Fenlason) - - - When using --cvs-exclude, the exclude items we get from a - per-directory's .cvsignore file once again only affect that one - directory (not all following directories too). The items are also - now properly word-split and parsed without any +/- prefix parsing. - - - When specifying the USER@HOST: prefix for a file, the USER part - can now contain an '@', if needed (i.e. the last '@' is used to - find the HOST, not the first). - - - Fixed some bugs in the handling of group IDs for non-root users: - (1) It properly handles a group that the sender didn't have a name - for (it would previously skip changing the group on any files in - that group). (2) If --numeric-ids is used, rsync no longer - attempts to set groups that the user doesn't have the permission - to set. - - - Fixed the "refuse options" setting in the rsyncd.conf file. - - - Improved the -x (--one-file-system) flag's handling of any mount- - point directories we encounter. It is both more optimal (in that - it no longer does a useless scan of the contents of the mount- - point dirs) and also fixes a bug where a remapped mount of the - original filesystem could get discovered in a subdir we should be - ignoring. - - - Rsync no longer discards a double-slash at the start of a filename - when trying to open the file. It also no longer constructs names - that start with a double slash (unless the user supplied them). - - - Path-specifying options to a daemon should now work the same with - or without chroot turned on. Previously, such a option (such as - --link-dest) would get its absolute path munged into a relative - one if chroot was not on, making that setting fairly useless. - Rsync now transforms the path into one that is based on the - module's base dir when chroot is not enabled. - - - Fixed a compatibility problem interacting with older rsync - versions that might send us an empty --suffix value without - telling us that --backup-dir was specified. - - - The "hosts allow" option for a daemon-over-remote-shell process - now has improved support for IPv6 addresses and a fix for systems - that have a length field in their socket structs. - - - Fixed the ability to request an empty backup --suffix when sending - files to an rsync daemon. - - INTERNAL: + - 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. - - Most of the I/O is now buffered, which results in a pretty large - speedup when running under MS Windows. (Craig Barratt) + - 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. - - Optimizations to the name-handling/comparing code have made some - significant reductions in user-CPU time for large file sets. + - 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. - - Some cleanup of the variable types make the code more consistent. + - 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. - - Reduced memory requirements of hard link preservation. - (J.W. Schultz) + - Added the --sockopts option for those few who want to customize the TCP + options used to contact a daemon rsync. - - Implemented a new algorithm for hard-link handling that speeds up - the code significantly. (J.W. Schultz and 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). - - The --hard-link option now uses the first existing file in the - group of linked files as the basis for the transfer. This - prevents the sub-optimal transfer of a file's data when a new - hardlink is added on the sending side and it sorts alphabetically - earlier in the list than the files that are already present on the - receiving side. + - 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. - - Dropped support for protocol versions less than 20 (2.3.0 released - 15 Mar 1999) and activated warnings for protocols less than 25 - (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz, - severally) + - 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. - - More optimal data transmission for --hard-links (protocol 28). + - New log-format options: %M (modtime), %U (uid), %G (gid), and %B + (permission bits, e.g. "rwxr-xrwt"). - - More optimal data transmission for --checksum (protocol 28). + - 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). - - Less memory is used when --checksum is specified. + - 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. - - Less memory is used in the file list (a per-file savings). + - 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. - - The generator is now better about not modifying the file list - during the transfer in order to avoid a copy-on-write memory - bifurcation (on systems where fork() uses shared memory). - Previously, rsync's shared memory would slowly become unshared, - resulting in real memory usage nearly doubling on the receiving - side by the end of the transfer. Now, as long as permissions - are being preserved, the shared memory should remain that way - for the entire transfer. + - Various new and updated diffs in the patches dir, including: acls.diff, + xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff. - - Changed hardlink info and file_struct + strings to use allocation - pools. This reduces memory use for large file-sets and permits - freeing memory to the OS. (J.W. Schultz) + INTERNAL: - - The 2 pipes used between the receiver and generator processes - (which are forked on the same machine) were reduced to 1 pipe and - the protocol improved so that (1) it is now impossible to have the - "redo" pipe fill up and hang rsync, and (2) trailing messages from - the receiver don't get lost on their way through the generator - over to the sender (which mainly affected hard-link messages and - verbose --stats output). + - 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. - - Improved the internal uid/gid code to be more portable and a - little more optimized. + - Some buffer sizes were expanded a bit, particularly on systems where + MAXPATHLEN is overly small (e.g. cygwin). - - The device numbers sent when using --devices are now sent as - separate major/minor values with 32-bit accuracy (protocol 28). - Previously, the copied devices were sent as a single 32-bit - number. This will make inter-operation of 64-bit binaries more - compatible with their 32-bit brethren (with both ends of the - connection are using protocol 28). Note that optimizations in the - binary protocol for sending the device numbers often results in - fewer bytes being used than before, even though more precision is - now available. + - If io_printf() tries to format more data than fits in the buffer, exit + with an error instead of transmitting a truncated buffer. - - Some cleanup of the exclude/include structures and its code made - things clearer (internally), simpler, and more efficient. + - If a va_copy macro is defined, lib/snprintf.c will use it when defining + the VA_COPY macro. - - The reading & writing of the file-list in batch-mode is now - handled by the same code that sends & receives the list over the - wire. This makes it much easier to maintain. (Note that the - batch code is still considered to be experimental.) + - Reduced the amount of stack memory needed for each level of directory + recursion by nearly MAXPATHLEN bytes. - BUILD CHANGES: + - 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. - - The configure script now accepts --with-rsyncd-conf=PATH to - override the default value of the /etc/rsyncd.conf file. + - 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. - - Fixed configure bug when running "./configure --disable-ipv6". + - Unified the f_name() and the f_name_to() functions. - - Fixed compilation problem on Tru64 Unix (having to do with - sockaddr.sa_len and sockaddr.sin_len). + - Improved the hash-table code the sender uses to handle checksums to make + it use slightly less memory and run just a little faster. DEVELOPER RELATED: - - Fixed "make test" bug when build dir is not the source dir. + - The diffs in the patches dir now require "patch -p1
