If + you are not parsing the numeric values out of this footer, a script + should be better off using the empty line prior to the footer as the + indicator that the verbose output is over. + + - The output from the --stats option was similarly affected to change + "written" to "sent" and "read" to "received". + + - Made sure that a filename that contains a newline gets mentioned with + each newline transformed into a question mark (which makes sure that + a filename can't span multiple lines nor cause an empty line to be + output). + 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). @@ -14,11 +33,18 @@ Changes since 2.6.2: 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, the receiver will - no longer keep the resulting file unless the --partial option was - specified.

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". + + - The --copy-links (-L) option no longer has the side-effect of telling + the receiving side to follow symlinks. See the --keep-dirlinks + option (mentioned below) for a way to specify that behavior. + + - 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 before dying (the local rsync used to just + die with a socket-write error). + + - 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. + + - Added a configure check for open64() without mkstemp64() so that we + can avoid using mkstemp() when such a combination is encountered. + This bypasses a problem writing out large temp files on OSes such as + AIX and HP-UX. + ENHANCEMENTS: - - The new option --keep-dirlinks (-K) allows you to symlink a directory - onto another patition on the receiving side and have rsync treat it + - 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).

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 for 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. @@ -53,26 +133,65 @@ Changes since 2.6.2: - 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 module + names. + + - The daemon's "refuse options" config item now allows you to match + option names using wildcards and/or the single-letter option 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(). + 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 timestamp used to be updated). + 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.
