NEWS for rsync 2.6.3 (UNRELEASED) Protocol: 28 (unchanged) Changes since 2.6.2: OUTPUT CHANGES: - For anyone who is parsing rsync's verbose output using a script, please note that the 2-line footer now uses the term "sent" instead of "wrote" and "received" instead of "read". If you are not parsing the numeric values out of this footer, your script would probably be better off using the empty line prior to the footer as the indicator that the verbose output is over. - The --stats option was similarly affected to change "written" to "sent" and "read" to "received". BUG FIXES: - Fixed a crash bug that might appear when --delete was used and multiple source directories were specified. - Fixed the 32-bit truncation of the file length when generating the checksums. - The --backup code no longer attempts to create some directories over and over again (generating warnings along the way). - 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. - If a file has a read error on the sending side or the reconstructed data doesn't match the expected checksum (perhaps due to the basis file changing during the transfer), the receiver will no longer retain the resulting file unless the --partial option was specified. (Note: for the read-error detection to work, neither side can be older than 2.6.3 -- older receivers will always retain the file, and older senders don't tell the receiver that the file had a read error.) - If a file gets resent in a single transfer and the --backup option is enabled, rsync no longer performs a duplicate backup (losing the original file in the process). - Fixed an age-old crash problem with --read-batch on a local copy (rsync was improperly assuming --whole-file for the local copy). - 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. - Got rid of a potential hang in the receiver when near the end of a phase. - When using --backup without a --backup-dir, rsync no longer preserves the modify time on directories. This avoids confusing NFS. - When --copy-links (-L) is specified, we now output a separate error for a symlink that has no referent instead of claiming that a file "vanished". - Error messages from the daemon server's option-parsing (such as refused options) now get sent back to the client (the server used to just exit because the socket wasn't in the right state to send the message). - Most errors that occur during a daemon transfer are now returned to the user in addition to being logged (some messages are intended to be daemon-only). - Fixed a bug in the daemon authentication code when using one of the batch-processing options. - We try to work around some buggy IPv6 implementations that fail to implement IPV6_V6ONLY. This should fix the "address in use" error that some daemons get when running on an OS with a buggy IPv6 implementation. Also, if the new code gets this error, we might suggest that the user specify --ipv4 or --ipv6 (if we think it will help). - When the remote rsync dies, make a better effort to recover any error messages it may have sent instead of just dying with a write error trying to send data over the socket. - When using --delete and a --backup-dir that contains files that are hard-linked to their destination equivalents, rsync now makes sure that removed files really get removed (works around a really weird rename() behavior). - Avoid a bogus run-time complaint about a lack of 64-bit integers when the int64 type is defined as an off_t and it actually has 64-bits. ENHANCEMENTS: - Added the --partial-dir=DIR option that lets you specify where to (temporarily) put a partially transferred file (instead of over- writing the destination file). E.g. --partial-dir=.rsync-partial - Added --keep-dirlinks (-K), which allows you to symlink a directory onto another partition on the receiving side and have rsync treat it as matching a normal directory from the sender. - Added the --inplace option that tells rsync to write each destination file without using a temporary file. The matching of existing data in the destination file can be severely limited by this, but there are also cases where this is more efficient (such as appending data). Use only when needed (see the man page for more details). - Added the "write only" option to the daemon's config file. - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) and documented all these options in the man page. - 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 rsync daemon-over-ssh code now looks for SSH_CONNECTION and SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address. - Added the --checksum-seed=N option for advanced users. - Batch writing/reading has a brand-new implementation that is simpler, fixes a few weird problems with the old code (such as no longer sprinkling the batch files into different dirs or even onto different systems), and is much less intrusive into the code (making it easier to maintain for the future). The new code generates just one data file instead of three, which makes it possible to read the batch via stdin. Also, the old requirement of using the same fixed checksum- seed for all batch processing has been removed. - If an rsync daemon has a module set with "list = no" (which hides its presence in the list of available modules), a user that fails to authenticate gets the same "unknown module" error that they would get if the module were actually unknown (while still logging the real error to the daemon's log file). This prevents fishing for modules names. INTERNAL: - Some cleanup in the exclude code has saved some per-exclude memory and made the code easier to maintain. - Improved the argv-overflow checking for a remote command that has a lot of args. - Use rsyserr() in the various places that were still calling rprintf() with strerror() as an arg. - If an rsync daemon is listening on multiple sockets (to handle both IPv4 and IPv6 to a single port), we now close all the unneeded file handles after we accept a connection (we used to close just one of them). - Optimized the handling of larger block sizes (rsync used to slow to a crawl if the block size got too large). Also cap the block size. - Optimized away a loop in hash_search(). - Make sure that a filename that contains a newline gets mentioned with each newline transformed into a question mark (which makes parsing the verbose output via script more dependable). BUILD CHANGES: - Added a "gen" target to rebuild most of the generated files, including configure, config.h.in, the man pages, and proto.h. - If "make proto" doesn't find some changes in the prototypes, the proto.h file is left untouched (its time-stamp used to always be updated). - The variable $STRIP (that is optionally set by the install-strip target's rule) was changed to $INSTALL_STRIP because some systems have $STRIP set in the environment. - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined. DEVELOPER RELATED: - The scripts in the testsuite dir were cleaned up a bit. - Some new diffs were added to the patches dir, and some accepted ones were removed.
