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 really old bug that caused --checksum (-c) to checksum all the + files encountered during the delete scan (ouch). + + - 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 hard-links work with symlinks and devices again. + - 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). + - If a device-file/special-file changes permissions, rsync now updates the permissions without recreating the file. @@ -31,44 +67,205 @@ Changes since 2.6.6: - 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. 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). + + - 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. + + - 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 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. + + - Fixed a bug where the --copy-links option would not affect implied + directories (see --relative) without --copy-unsafe-links. + + - Got rid of the need for --force to be used in some circumstances with + --delete-after (making it consistent with --delete-before/-during). + + - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this + when a file is too large (rsync handles the write error). + ENHANCEMENTS: - - 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 --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 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".) - If lutimes() and/or lchmod() are around, use them to allow the preservation of attributes on symlinks. - - 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. + - The --link-dest option now affects symlinks and devices (when possible). + + - 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.) - 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 would only + 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 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. - - 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 --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. - - Some minor documentation improvements. + - 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. - - Updated some diffs in the patches dir. + - 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 --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. + + - 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 connection and also each module-list request + that it receives. + + - New log-format options: %M (modtime), %U (uid), %G (gid), and %B + (permission bits, e.g. "rwxr-xrwt"). + + - 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). + + - A daemon now supersedes its minimal SIGCHLD handler with the standard + PID-remembering version after forking to handle the request. 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. + + - Added the --copy-dirlinks option, a more limited version of --copy-links. + + - The sender's hash table for checksum information was improved to make it + more efficient when updating really large files (starting from around + 2.5GB, but most visibly for much larger files). This prevents the hash + table from getting overloaded, which saves CPU time (and real time) at + the expense of a little extra memory (and it actually saves memory for + normal sized files). + + - 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. + + - Various new and updated diffs in the patches dir, including: acls.diff, + xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff. 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). @@ -78,9 +275,35 @@ Changes since 2.6.6: - 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.
