Prior versions used to output too many creation events for + matching items. - - Fixed a bug in the reading of the secrets file (by the daemon) and - the password file (by the client): the files no longer need to be - terminated by a newline for their content to be read in. + - 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 a file has a read error on the sending side, the receiver will - no longer keep the resulting file unless the --partial option was - specified. (Note: both sides must be running 2.6.3 for this to - work -- older receivers always keep the file, and older senders - don't tell the receiver that the file was not read correctly.) + - A negated filter rule now sends the negation option when sending the + filter rules. - - Fixed an age-old crash problem with --read-batch on a local copy - (rsync was improperly assuming --whole-file for the local copy). + - Fixed a problem with the --out-format (aka --log-format) option: it + would output superfluous directory information for a non-daemon rsync. - - Files specified in the daemon's "exclude" or "exclude from" config - items are now excluded from being uploaded (assuming that the module - allows uploading at all) in addition to the old download exclusion. + - 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. - - When using --backup without a --backup-dir, rsync no longer preserves - the modify time on directories. This avoids confusing NFS. + - 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. - - Fixed a bug in the daemon authentication code when using one of the - batch-processing options. + - Make sure that directory permissions of a newly-created destination + directory are handled right when --perms is left off. + + - Improved --hard-link so that more corner cases are handled correctly + when combined with options such as --link-dest and/or --ignore-existing. ENHANCEMENTS: - - Added the "write only" option to the daemon's config file. + - 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. + + - Added the --iconv option, which allows rsync to convert filenames from + one character-set to another during the transfer. The default is to make + this feature available as long as your system has iconv_open(). If + compilation fails, specify --disable-iconv to configure and rebuild. If + you want rsync to perform character-set conversions by default, you can + specify --enable-iconv=CONVERT_STRING with the default value for the + --iconv option that you wish to use. For example, --enable-iconv=. is a + good choice. See the rsync man page for an explanation of the --iconv + option's settings. + + - Added the --skip-compress=LIST option to override of the default list of + file suffixes that will not be compressed when using --compress. + + - The --max-delete option now outputs a warning if it skipped any file + deletions, including a count of how many deletions were skipped. (Older + versions just silently stopped deleting things.) + + - You may specify --max-delete=0 to a 3.0.0 client to request that it warn + about any files that it wants to delete without deleting anything. If + you're not sure what version the client is, you can use the less-obvious + --max-delete=-1, as old and new versions will both treat that as the + same request (though older versions don't warn). + + - 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). + + - A lot more --no-OPTION override options are now supported. - - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) - and documented all these options in the man page. + INTERNAL: - - Improved the handling of the --bwlimit option so that it's less - bursty, more accurate, and works properly over a larger range of - values. + - The file-list sorting algorithm now uses a sort that keeps any same- + named items in the same order as they were specified. This allows + rsync to always ensure that the first of the duplicates is the one + that will be included in the copy. The new sort was also faster + than the glibc version of qsort() and mergesort() in my testing. - - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and - SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address. + - Rsync now supports the transfer of 64-bit timestamps (time_t values). - - Added the --checksum-seed=N option for advanced users. + - Fixed a build problem with older (2.x) versions of gcc. - INTERNAL: + - Added some isType() functions that make dealing with signed characters + easier without forcing variables via casts. + + - Upgraded the included popt version to 1.10.2 and improved its use of + string-handling functions. + + - Added missing prototypes for compatibility functions from the lib dir. - - Some cleanup in the exclude code has saved some per-exclude memory - and made the code easier to maintain. + - Configure determines if iconv() has a const arg, allowing us to avoid a + compiler warning. - - Use rsyserr() in the various places that were still calling - rprintf() with strerror() as an arg. + - Made the sending of some numbers more efficient for protocol 30. - BUILD CHANGES: + - Make sure that a daemon process doesn't mind if the client was weird and + omitted the --server option. - - Added a "gen" target to rebuild most of the generated files, - including configure, config.h.in, the man pages, and proto.h. + - Improved the use of "const" on pointers. - - If "make proto" doesn't find some changes in the prototypes, the - proto.h file is left untouched (its timestamp used to be updated). + - Improved J.W.'s pool_alloc routines to add a way of freeing older + sections of a pool's memory. DEVELOPER RELATED: - - The scripts in the testsuite dir were cleaned up a bit. + - Rsync is now licensed under the GPLv3 or later. + - 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).
