Any non-printable character is - output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash - is now output as "\\". Rsync also uses your locale setting, which - can make it treat fewer high-bit characters as non-printable. - - - If rsync received an empty file list when pulling files, it would - output a "nothing to do" message and exit with a 0 (success) exit - status, even if the remote rsync returned an error (it did not do - this under the same conditions when pushing files). This was changed - to make the pulling behavior the same as the pushing behavior: we - now do the normal end-of-run outputting (depending on options) and - exit with the appropriate exit status. +NEWS for rsync 3.0.0 (UNRELEASED) +Protocol: 30 (changed) +Changes since 2.6.9: BUG FIXES: - - A crash bug was fixed when a daemon had its "path" set to "/", did - not have chroot enabled, and used some anchored excludes in the - rsyncd.conf file. + - Fixed the output of -ii when combined with one of the --*-dest options: + it now itemizes all the items, not just the changed ones. - - Fixed a bug in the transfer of a single file when -H is specified - that might have caused an infinite loop or perhaps a crash. + - 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 case where the generator might try to tweak the write - permissions of a read-only directory in list-only mode. + - 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. - - If --compare-dest or --link-dest uses a locally-copied file as the - basis for an updated version, log this better when --verbose or -i - is in effect. + - A negated filter rule now sends the negation option when sending the + filter rules. - - Fixed the accidental disabling of --backup during the --delete-after - processing. + - Fixed a problem with the --out-format (aka --log-format) option: it + would output superfluous directory information for a non-daemon rsync. - - Restored the ability to use the --address option in client mode (in - addition to its use in daemon mode). + - 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. - - Make sure that some temporary progress information from the delete - processing does not get left on the screen when it is followed by a - newline. + - 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. - - When --existing skips a directory with extra verbosity, refer to it - as a "directory", not a "file". - - - When transferring a single file to a different-named file, any - generator messages that are source-file related no longer refer to - the file by the destination filename. - - - Fixed a bug where hard-linking a group of files might fail if the - generator hasn't created a needed destination directory yet. - - - Fixed a bug where a hard-linked group of files that is newly-linked - to a file in a --link-dest dir doesn't link the files from the rest - of the cluster. - - - When deleting files with the --one-file-system (-x) option set, rsync - no longer tries to remove files from inside a mount-point on the - receiving side. - - - Fixed a compatibility problem when using --cvs-ignore (-C) and - sending files to an older rsync without using --delete. - - - Make sure that a "- !" or "+ !" include/exclude pattern does not - trigger the list-clearing action that is reserved for "!". - - - Avoid a timeout in the generator when the sender/receiver aren't - handling the generator's checksum output quickly enough. - - - Fixed the ommission of some directories in the delete processing when - --relative (-R) was combined with a source path that had a trailing - slash. - - - Make sure that --max-size doesn't affect a device or a symlink. - - - Make sure that a system with a really small MAXPATHLEN does not cause - the buffers in readfd_unbuffered() to be too small to receive normal - messages. (This mainly affected Cygwin.) - - - If a source filename ends with "..", treat it as if "../" had been - specified (so that we don't copy files to the parent dir of the - destination). - - - If --delete is combined with a file-listing rsync command (i.e. no - transfer is happening), avoid outputting a warning that we couldn't - delete anything. - - - If --stats is specified with --delete-after, ensure that all the - "deleting" messages are output before the statistics. - - - Improved one "if" in the deletion code that was only checking errno - for ENOTEMPTY when it should have also been checking for EEXIST. + - Make sure that directory permissions of a newly-created destination + directory are handled right when --perms is left off. ENHANCEMENTS: - - Added the --only-write-batch=FILE option that may be used (instead - of --write-batch=FILE) to create a batch file without doing any - actual updating of the destination. This allows you to divert all - the file-updating data away from a slow data link (as long as you - are pushing the data to the remote server when creating the batch). - - - When the generator is taking a long time to fill up its output buffer - (e.g. if the transferred files are few, small, or missing), it now - periodically flushes the output buffer so that the sender/receiver - can get started on the files sooner rather than later. - - - Improved the keep-alive code to handle a long silence between the - sender and the receiver that can occur when the sender is receiving - the checksum data for a large file. - - - Improved the auth-errors that are logged by the daemon to include - some information on why the authorization failed (wrong user, - password mismatch, etc.). (The client-visible message is unchanged.) - - - Improved the client's handling of an "@ERROR" from a daemon so that - it does not complain about an unexpectedly closed socket (since we - really did expect the socket to close). - - - If the daemon can't open the log-file specified in rsyncd.conf, fall - back to using syslog (and log an appropriate warning). This is - better than what was typically a totally silent failure (since a - daemon is not usually run with the --no-detach option that was - necessary to see the error on stderr). - - - The man pages now consistently refer to an rsync daemon as a "daemon" - to distinguish it from a server in a non-daemon transfer. - - - Made a small change to the rrsync script (restricted rsync -- in the - support dir) to make a read-only server reject all --remove-* options - when sending files (to future-proof it against the possibility of - other similar options being added at some point). + - 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). INTERNAL: - - Rsync now calls setlocale(LC_CTYPE, "") to enable isprint() to better - discern which filename characters need to be escaped in messages. + - Rsync now supports the transfer of 64-bit timestamps (time_t values). + + - Fixed a build problem with older (2.x) versions of gcc. - - Improved the naming of the log-file open/reopen/close functions. + - Added some isType() functions that make dealing with signed characters + easier without forcing variables via casts. - - Removed some protocol compatibility code that was only needed to help - someone running a pre-release of 2.6.4. + - Upgraded the included popt version to 1.10.2 and improved its use of + string-handling functions. - BUILD CHANGES: + - Added missing prototypes for compatibility functions from the lib dir. - - Fixed a bug in the SUPPORT{,_HARD}_LINKS defines which prevented - rsync from being built without symlink or hard-link support. + - Configure determines if iconv() has a const arg, allowing us to avoid a + compiler warning. - - You can use --disable-locale to turn off any use of setlocale(). + - Made the sending of some numbers more efficient for protocol 30. - - Configure now disables the use of mkstemp() under HP-UX (since they - refuse to fix its broken handling of large files). + - Make sure that a daemon process doesn't mind if the client was weird and + omitted the --server option. - - Configure now explicitly checks for the lseek64() function so that - the code can use HAVE_LSEEK64 instead of inferring lseek64()'s - presence based on the presence of the off64_t type. + - Improved the use of "const" on pointers. - - Some minor enhancements to the test scripts. + DEVELOPER RELATED: - - Added a few new diffs to the patches dir, including a patch that - enables the optional copying of extended attributes. + - 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).
