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) - - * Fixed configure bug when running "./configure --disable-ipv6". - - * Fixed "make test" bug when build dir is not the source dir. - - * When using --cvs-exclude, the exclude items we get from a - directory's .cvsignore file once again only affect that one - directory (and not all following directories too). - - * When transferring a file that has group 0 with -g specified - (typically via -a) and not enough privs to retain the group, - rsync no longer complains about "chown" failing. - - * 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. + - An rsync daemon that is receiving files with "use chroot = no" no longer + sanitizes the symlink target strings. This means that each symlink's + value will now be accepted (and thus returned) with its symlink info + intact. Also, in order to keep things safe, any option that tells a + non-chroot daemon to treat some symlinks as their referent (such as + --copy-links or --keep-dirlinks) now manually checks the symlink chain + to ensure that the symlinks do not try to escape past the top of the + module's path. Both these changes make a non-chroot daemon behave the + same as a chroot daemon with regard to symlinks, and also avoids a + potential problem where a pre-existing symlink could have escaped the + module's hierarchy. + + - Fixed a overzealous sanitizing bug in the handling of the --*-dest + options (--link-dest, --copy-dest, and --compare-dest): 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. + + - 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.) + + - Make sure that the --link-dest option can still do its job even when -I + or --size-only is specified. + + - 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 "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 remaped - mount of the original filesystem could get discovered on a - disk 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). - - * Fixed compilation problem on Tru64 Unix (having to do with - sockaddr.sa_len and sockaddr.sin_len). - - INTERNAL: - - * Most of the I/O is now buffered, which results in a pretty - large speedup when running under MS Windows. (Craig Barratt) - - * Optimizations to the name-handling/comparing code have made - some significant reductions in user-CPU time for large file - sets. - - * Some variable-type cleanup that makes the code more consistent. - - * Reduced memory requirements of hard link preservation. - (J.W. Schultz) - - * Implemented a new algorithm for hard-link handling that speeds - up the code significantly. (J.W. Schultz and Wayne Davison) - - * 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. - - * 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) - - * More optimal data transmission for --hard-links (protocol 28). - - * More optimal data transmission for --checksum (protocol 28). - - * Less memory is used when --checksum is specified. + ENHANCEMENTS: - * Less memory is used in the file list (a per-file savings). + - ... - * Changed hardlink info and file_struct + strings to use - allocation pools. This reduces memory use for large - filesets and permits freeing memory to the OS. (J.W. Schultz) + DEVELOPER RELATED: - * 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 (the latter mainly affected - hard-link messages and verbose --stats output). + - The acls.diff and xattrs.diff patches have received a bunch of work to + make them much closer to being acceptable in the main distribution. - * 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. + - Updated config.guess and config.sub to their 2006-02-23 version. - * Improved the internal uid/gid code to be more portable and - a little more optimized. + - Updated various files to include the latest FSF address and to have + consistent opening comments.
