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 (-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. +Changes since 2.6.7: BUG FIXES: - - Fixed a really old bug that caused --checksum (-c) to checksum all the - files encountered during the delete scan (ouch). + - Fixed a bug in the exclude code where an anchored exclude without any + wildcards fails to match an absolute source arg, but only when --relative + is in effect. - - 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). + - Improved the I/O code for the generator to fix a potential hang when the + receiver gets an EOF on the socket but the generator's select() call + never indicates that the socket is writable for it to be notified about + the EOF. (This can happen when using stunnel). - - Made hard-links work with symlinks and devices again. + - Fixed a problem with the file-reading code where a failed read (such as + that caused by a bad sector) would not advance the file's read-position + beyond the failed read's data. - - 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 a logging bug where the "log file" directive was not being honored + in a single-use daemon (one spawned by a remote-shell connection or by + init). - - If a device-file/special-file changes permissions, rsync now updates the - permissions without recreating the file. + - If rsync cannot honor the --delete option, we output an error and exit + instead of silently ignoring the option. - - 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 bug in the --link-dest code that prevented special files (such as + fifos) from being linked. - - 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. - - - 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). + - The ability to hard-link symlinks and special files is now determined at + configure time instead of at runtime. This fixes a bug with --link-dest + creating a hard-link to a symlink's referent on a BSD system. 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 (-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 + - In daemon mode, if rsync fails to bind to the requested port, the + error(s) returned by socket() and/or bind() are now logged. - - 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. + - When we output a fatal error, we now output the version of rsync in the + message. - - Allow the --temp-dir option to be specified when starting a daemon, which - sets the default temporary directory for incoming files. + - The rsyncstats script in "support" has an improved line-parsing regex + that is easier to read and also makes it to parse syslog-generated lines. - - 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. - - 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). - - - 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. + - A new script in "support": file-attr-restore, can be used to restore the + attributes of a file-set (the permissions, ownership, and group info) + taken from the cached output of a "find ARG... -ls" command.
