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 the output of all file types consistent when using a --*-dest + option. Prior versions used to output too many creation events for + matching items. - - 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.) + - 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. - - 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. + - A negated filter rule now sends the negation option when sending the + filter rules. - - 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). + - Fixed a problem with the --out-format (aka --log-format) option: it + would output superfluous directory information for a non-daemon rsync. - - If the receiving side fails to create a directory, it will now skip - trying to update everything that is inside that directory. + - 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. - - 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. + - 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. - - 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). + - Make sure that directory permissions of a newly-created destination + directory are handled right when --perms is left off. - - 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. + ENHANCEMENTS: - - 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). + - 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). - - Fixed a recent bug where --delete was not working when transferring from - the root (/) of the filesystem with --relative enabled. + INTERNAL: - - Fixed a recent bug where an --exclude='*' could affect the root (/) of - the filesystem with --relative enabled. + - Rsync now supports the transfer of 64-bit timestamps (time_t values). - - 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 a build problem with older (2.x) versions of gcc. - - 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. + - Added some isType() functions that make dealing with signed characters + easier without forcing variables via casts. - - Fixed a bug in the daemon's "incoming chmod" rule: newly-created - directories no longer get the 'F' (file) rules applied to them. + - Upgraded the included popt version to 1.10.2 and improved its use of + string-handling functions. - - Fixed an infinite loop bug when a filter rule was rejected due to being - overly long. + - Added missing prototypes for compatibility functions from the lib dir. - ENHANCEMENTS: + - Configure determines if iconv() has a const arg, allowing us to avoid a + compiler warning. - - 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. - - INTERNAL: + - Made the sending of some numbers more efficient for protocol 30. - - Did a code audit using IBM's code checker program and made several - changes, including: replacing most of the strcpy() and sprintf() calls - with strlcpy(), snprintf(), and memcpy(); adding a 0-value to an enum - that had been intermingling a literal 0 with the defined enum values. + - Make sure that a daemon process doesn't mind if the client was weird and + omitted the --server option. - - Fixed a potential bug in f_name_cmp() when both the args are a - top-level "." dir (which doesn't happen in normal operations). - - - Changed exit_cleanup() so that it can never return instead of exit. - The old code might return if it found the exit_cleanup() function - was being called recursively. The new code segments the exit code - so that any recursive calls move on to the next step of the exit - processing. + - Improved the use of "const" on pointers. DEVELOPER RELATED: - - 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 rsync.yo and rsyncd.conf.yo files have been updated to work - better with the latest yodl 2.x releases. - - - Updated config.guess and config.sub to their 2006-02-23 version. - - - Updated various files to include the latest FSF address and to have - consistent opening comments. + - Rsync now has a way of handling protocol-version changes during the + development of a new protocol version. This exchange of sub-version + info does not interfere with the {MIN,MAX}_PROTOCOL_VERSION checking + in older versions (which would be the case if every minor change made + to the protocol in CVS incremented the main PROTOCOL_VERSION value).
