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 2.6.8: BUG FIXES: - - Fixed a really old bug that caused --checksum (-c) to checksum all the - files encountered during the delete scan (ouch). + - If rsync is interrupted via a handled signal (such as SIGINT), it will + once again clean-up its temp file from the destination dir. - - 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 an overzealous sanitizing bug in the handling of the --link-dest, + --copy-dest, and --compare-dest options to a daemon without chroot: if + the copy's destination dir is deeper than the top of the module's path, + these options now accept a safe number of parent-dir (../) references + (since these options are relative to the destination dir). The old code + incorrectly chopped off all "../" prefixes for these options, no matter + how deep the destination directory was in the module's hierarchy. - - Made hard-links work with symlinks and devices again. + - Fixed a bug where a deferred info/error/log message could get sent + directly to the sender instead of being handled by rwrite() in the + generator. This fixes an "unexpected tag 3" fatal error, and should + also fix a potential problem where a deferred info/error message from + the receiver might bypass the log file and get sent only to the client + process. (These problems could only affect an rsync daemon that was + receiving files.) - - 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 bug where using --dry-run with a --*-dest option with a path + relative to a directory that does not yet exist: the affected option + gets its proper path value so that the output of the dry-run is right. - - If a device-file/special-file changes permissions, rsync now updates the - permissions without recreating the file. + - Fixed a bug in the %f logfile escape when receiving files: the + destination path is now included in the output (e.g. you can now tell + when a user specifies a subdir inside a module). - - 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. + - If the receiving side fails to create a directory, it will now skip + trying to update everything that is inside that directory. - - 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 --link-dest is specified with --checksum but without --times, rsync + will now allow a hard-link to be created to a matching link-dest file + even when the file's modify-time doesn't match the server's file. - - Reject the combination of --inplace and --sparse since the sparse-output - algorithm doesn't work when overwriting existing data. + - The daemon now calls more timezone-using functions prior to doing a + chroot. This should help some C libraries to generate proper timestamps + from inside a chrooted daemon (and to not try to access /etc/timezone + over and over again). - - Fixed the directory name in the error that is output when pop_dir() - fails. + - Fixed a bug in the handling of an absolute --partial-dir=ABS_PATH option: + it now deletes an alternate basis file from the partial-dir that was used + to successfully update a destination file. - - Really fixed the parsing of a "!" entry in .cvsignore files this time. + - Fixed a bug in the handling of --delete-excluded when using a per-dir + merge file: the merge file is now honored on the receiving side, and + only its unqualified include/exclude commands are ignored (just as is + done for global include/excludes). - - 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). + - Fixed a recent bug where --delete was not working when transferring from + the root (/) of the filesystem with --relative enabled. - - 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 recent bug where an --exclude='*' could affect the root (/) of + the filesystem with --relative enabled. - - Fixed some glitches in the double-verbose output when using --copy-dest, - --link-dest, or --compare-dest. + - When --inplace creates a file, it is now created with owner read/write + permissions (0600) instead of no permissions at all. This avoids a + problem continuing a transfer that was interrupted (since --inplace + will not update a file that has no write permissions). - - Fixed the matching of the dont-compress items (e.g. *.gz) against files - that have a path component containing a slash. + - If either --remove-source-files or --remove-sent-files is enabled and we + are unable to remove the source file, rsync now outputs an error. - - 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). + - Fixed a bug in the daemon's "incoming chmod" rule: newly-created + directories no longer get the 'F' (file) rules applied to them. 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 - - - 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. - - 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. + - Added the --log-file=FILE and --log-file-format=FORMAT options. These + can be used to tell any rsync to output what it is doing to a log file. + They work with a client rsync, a non-daemon server rsync (see the man + page for instructions), and also allows the overriding of rsyncd.conf + settings when starting a daemon. + + - The --log-format option was renamed to be --out-format to avoid confusing + it with affecting the log-file output. (The old option remains as an + alias for the new to preserve backward compatibility.) + + - Made "log file" and "syslog facility" settable on a per-module basis in + the daemon's config file. + + - Added the --remove-source-files option as a replacement for the (now + deprecated) --remove-sent-files option. This new option removes all + non-dirs from the source directories, even if the file was already + up-to-date. This fixes a problem where interrupting an rsync that + was using --remove-sent-files and restarting it could leave behind + a file that the earlier rsync synchronized, but didn't get to remove. + (The deprecated --remove-sent-files is still understood for now, and + still behaves in the same way as before.) + + - Added a new environment variable to the pre-/post-xfer exec commands (in + the daemon's config file): RSYNC_PID. This value will be the same in + both the pre- and post-xfer commands, so it can be used if the pre-xfer + command wants to cache some arg/request info for the post-xfer command.
