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-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. +NEWS for rsync 3.0.0 (UNRELEASED) +Protocol: 30 (changed) +Changes since 2.6.9: BUG FIXES: - - Fixed a really old bug that caused --checksum (-c) to checksum all the - files encountered during the delete scan (ouch). + - Fixed the output of -ii when combined with one of the --*-dest options: + it now itemizes all the items, not just the changed ones. - - 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). + - Made the output of all file types consistent when using a --*-dest + option. Prior versions used to output too many creation events for + matching items. - - Made hard-links work with symlinks and devices again. + - The code that waits for a child pid now handles being interrupted by a + signal. This fixes a problem with the pre-xfer exec function not being + able to get the exit status from the script. - - 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). + - A negated filter rule now sends the negation option when sending the + filter rules. - - If a device-file/special-file changes permissions, rsync now updates the - permissions without recreating the file. + - Fixed a problem with the --out-format (aka --log-format) option: it + would output superfluous directory information for a non-daemon rsync. - - 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 problem with -vv (double --verbose) and --stats when "pushing" + files (which includes local copies). Version 2.6.9 would complete the + copy, but exit with an error when the receiver output its memory stats. - - 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. + - If --password-file is used on a non-daemon transfer, rsync now complains + and exits. This should help users figure out that they can't use this + option to control a remote shell's password prompt. - - Reject the combination of --inplace and --sparse since the sparse-output - algorithm doesn't work when overwriting existing data. - - - Fixed the directory name in the error that is output when pop_dir() - fails. - - - Really fixed the parsing of a "!" entry in .cvsignore files this time. - - - 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. - - - Fixed some glitches in the double-verbose output when using --copy-dest, - --link-dest, or --compare-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. - - - 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). + - Make sure that directory permissions of a newly-created destination + directory are handled right when --perms is left off. 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). - - - 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). - - - 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 options --human-readable (-h) and --si change the output of the - --stats and the end-of-run summary to be easier to read. - - - If lutimes() and/or lchmod() are around, use them to allow the - preservation of attributes on symlinks. - - - The --link-dest option now affects symlinks and devices (when possible). - - - Improved the output of hard-linked and copied files when using - --link-dest, --copy-dest, or --compare-dest. - - - 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.) - - - 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). - - - 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. - - - Added the --chmod=MODE option that allows the destination permissions to - be changed from the source permissions. E.g. --chmod=g+w,o-rwx - - - 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. - - - 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. - - - 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 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. - - - 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). - - - 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. - - - 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. - - - 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. - - - Added the --sockopts option for those few who want to customize the TCP - options used to contact a daemon rsync. - - - 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). - - - 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. - - - 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 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. + - A new incremental-recursion algorithm is now used when rsync is talking + to another 3.0.0 version. This starts the transfer going more quickly + (before all the files have been found), and requires much less memory. + See the --recursive option in the manpage for some restrictions. + + - The default --delete algorithm is now --delete-during when talking to a + 3.x rsync. This is a faster scan than using --delete-before (which is + the default when talking to older rsync versions), and is compatible with + the new incremental recursion mode. + + - Added the --delete-delay option, which is a more efficient way to delete + files at the end of the transfer without needing a separate delete pass. + + - Added the --acls (-A) option to preserve Access Control Lists. This is + an improved version of the prior patch that was available. (If you need + to have backward compatibility with old, patched versions, the new + acls.diff patch that will add that.) + + - Added the --xattrs (-X) option to preserver extended attributes. This is + an improved version of the prior patch that was available. (If you need + to have backward compatibility with old, patched versions, the new + xattrs.diff patch that will add that.) + + - Added the --fake-super option that allows a non-super user to preserve + all attributes of a file by using a special extended-attribute idiom. + There is also an analogous "fake super" option for an rsync daemon. + + - You may specify --max-delete=0 to a 3.0.0 client as long as the receiving + side is at least version 3.0.0. This means that you can pull from an + older rsync with this option, but pushing to an older rsync will generate + an error. *Be sure to never specify a 0 value to an older rsync client, + or it will be silently ignored.* + + - The --hard-link option now uses less memory on both the sending and + receiving side for all protocol versions. For protocol 30, the use of a + hashtable on the sending side allows us to more efficiently convey to the + receiver what files are linked together. This reduces the amount of data + sent over the socket by a considerable margin (rather than adding more + data), and limits the in-memory storage of the device+inode information + to just the sending side for the new protocol 30, or to the receiving + side when speaking an older protocol (note that older rsync versions kept + the device+inode information on both sides). INTERNAL: - - 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). + - Rsync now supports the transfer of 64-bit timestamps (time_t values). - - If io_printf() tries to format more data than fits in the buffer, exit - with an error instead of transmitting a truncated buffer. + - Fixed a build problem with older (2.x) versions of gcc. - - If a va_copy macro is defined, lib/snprintf.c will use it when defining - the VA_COPY macro. + - Added some isType() functions that make dealing with signed characters + easier without forcing variables via casts. - - Reduced the amount of stack memory needed for each level of directory - recursion by nearly MAXPATHLEN bytes. + - Upgraded the included popt version to 1.10.2 and improved its use of + string-handling functions. - - 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. + - Added missing prototypes for compatibility functions from the lib dir. - - 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. + - Configure determines if iconv() has a const arg, allowing us to avoid a + compiler warning. - - Unified the f_name() and the f_name_to() functions. + - Made the sending of some numbers more efficient for protocol 30. - DEVELOPER RELATED: + - Make sure that a daemon process doesn't mind if the client was weird and + omitted the --server option. - - The diffs in the patches dir now require "patch -p1
