(Wayne Davison) + - Please note that the 2-line footer (output when verbose) 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, a script + would 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". - * Length of csum2 is now per-file starting with protocol verison - 27. (J.W. Schultz) + - Rsync ensures that a filename that contains a newline gets mentioned + with each newline transformed into a question mark (which prevents a + filename from causing an empty line to be output). - * Per-file dynamic block size is now sqrt(file length). - The per-file checksum size is determined according - to an algorythm provided by Donovan Baarda which - reduces the probability of rsync algorithm - corrupting data and falling back using the whole md4 - checksums. (J.W. Schultz, Donovan Baarda) + BUG FIXES: - * The --stats option no longer includes the (debug) malloc summary - unless the verbose option was specified at least twice. + - Fixed a crash bug that might appear when --delete was used and + multiple source directories were specified. - BUG FIXES: + - Fixed the 32-bit truncation of the file length when generating the + checksums. - * For protocol version >= 27, mdfour_tail() is called when the - block size (including checksum_seed) is a multiple of 64. - Previously it was not called, giving the wrong MD4 checksum. - (Craig Barratt) - - * For protocol version >= 27, a 64 bit bit counter is used in - mdfour.c as required by the RFC. Previously only a 32 bit bit - counter was used, causing incorrect MD4 file checksums for - file sizes >= 512MB - 4. (Craig Barratt) + - The --backup code no longer attempts to create some directories + over and over again (generating warnings along the way). - * Fixed a crash bug when interacting with older rsync versions and - multiple files of the same name are destined for the same dir. - (Wayne Davison) + - 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. - * Keep tmp names from overflowing MAXPATHLEN. + - 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.) - * Make --link-dest honor the absence of -p, -o, and -g. + - If a file gets resent in a single transfer and the --backup option + is enabled, rsync no longer performs a duplicate backup (it used to + overwrite the original file in the backup area). - * Made rsync treat a trailing slash in the destination in a more - consistent manner. + - 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 some exclude/include matching bugs when using wild-cards. - For instance, "**/foo" now matches at the root, "CVS/R*" now - matches beyond the root, and "foo**bar" is matched against the - path, not just the trailing name. (Wayne Davison) + - 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. - INTERNAL: + - 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. - * Eliminated vestigial support for old versions that we stopped - supporting. (J.W. Schultz) + - 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). - * Simplified some of the option-parsing code. (Wayne Davison) + - 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). -NEWS for rsync version 2.5.6, aka the dwd-between-jobs release -Protocol: 26 (unchanged) -Changes since version 2.5.5: + - 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. + + - Fixed an age-old crash problem with --read-batch on a local copy + (rsync was improperly assuming --whole-file for the local copy). + + - When --dry-run (-n) is used and the destination directory does not + exist, rsync now produces a correct report of files that would be + sent instead of dying with a chdir() error. ENHANCEMENTS: - * The --delete-after option now implies --delete. (Wayne Davison) + - 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 - * The --suffix option can now be used with --backup-dir. (Michael - Zimmerman) + - 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. - * Combining "::" syntax with the -rsh/-e option now uses the - specified remote-shell as a transport to talk to a (newly-spawned) - server-daemon. This allows someone to use daemon features, such - as modules, over a secure protocol, such as ssh. (JD Paul) + - 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). - * The rsync:// syntax for daemon connections is now accepted in the - destination field. + - Added the "write only" option for the daemon's config file. - * If the file name given to --include-from or --exclude-from is "-", - rsync will read from standard input. (J.W. Schultz) + - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) + and documented all these options in the man page. - * New option --link-dest which is like --compare-dest except that - unchanged files are hard-linked in to the destination directory. - (J.W. Schultz) + - Improved the handling of the --bwlimit option so that it's less + bursty, more accurate, and works properly over a larger range of + values. - * Don't report an error if an excluded file disappears during an - rsync run. (Eugene Chupriyanov and Bo Kersey) + - 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 .svn to --cvs-exclude list to support subversion. (Jon - Middleton) + - Added the --checksum-seed=N option for advanced users. - * Properly support IPv6 addresses in the rsyncd.conf "hosts allow" - and "hosts deny" fields. (Hideaki Yoshifuji) + - 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 over a remote shell. Also, the old requirement of forcing the + same fixed checksum-seed for all batch processing has been removed. - * Changed exclude file handling to permit DOS or MAC style line - terminations. (J.W. Schultz) + - 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. - * Ignore errors from chmod when -p/-a/--preserve-perms is not set. - (Dave Dykstra) + - The daemon's "refuse options" config item now allows you to match + option names using wildcards and/or the single-letter option names. - BUG FIXES: + - The finished file now gets its permissions and modified-time updated + before it gets moved into place. - * Fix "forward name lookup failed" errors on AIX 4.3.3. (John - L. Allen, Martin Pool) + - Lots of documentation improvements in the exclude/include sections. - * Generate each file's rolling-checksum data as we send it, not - in a separate (memory-eating) pass before hand. This prevents - timeout errors on really large files. (Stefan Nehlsen) + INTERNAL: - * Fix compilation on Tru64. (Albert Chin, Zoong Pham) + - Some cleanup in the exclude code has saved some per-exclude memory + and made the code easier to maintain. - * Better handling of some client-server errors. (Martin Pool) + - Improved the argv-overflow checking for a remote command that has a + lot of args. - * Fixed a crash that would occur when sending a list of files that - contains a duplicate name (if it sorts to the end of the file - list) and using --delete. (Wayne Davison) + - Use rsyserr() in the various places that were still calling rprintf() + with strerror() as an arg. - * Fixed the file-name duplicate-removal code when dealing with multiple - dups in a row. (Wayne Davison) + - 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). - * Fixed a bug that caused rsync to lose the exit status of its child - processes and sometimes return an exit code of 0 instead of showing - an error. (David R. Staples, Dave Dykstra) + - Optimized the handling of larger block sizes (rsync used to slow to a + crawl if the block size got too large). - * Fixed bug in --copy-unsafe-links that caused it to be completely - broken. (Dave Dykstra) + - Optimized away a loop in hash_search(). - * Prevent infinite recursion in cleanup code under certain circumstances. - (Sviatoslav Sviridov and Marc Espie) + - Some improvements to the sanitize_path() and clean_fname() functions + makes them more efficient and produce better results (while still + being compatible with the file-name cleaning that gets done on both + sides when sending the file-list). - * Fixed a bug that prevented rsync from creating intervening directories - when --relative-paths/-R is set. (Craig Barratt) + - Got rid of alloc_sanitize_path() after adding a destination-buffer + arg to sanitize_path() made it possible to put all the former's + functionality into the latter. - * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara) + BUILD CHANGES: - INTERNAL: + - 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). - * Many code cleanups and improved internal documentation. (Martin - Pool, Nelson Beebe) + - 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. - * Portability fixes. (Dave Dykstra and Wayne Davison) + - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined. - * More test cases. (Martin Pool) + DEVELOPER RELATED: - * Some test-case fixes. (Brian Poole, Wayne Davison) + - The scripts in the testsuite dir were cleaned up a bit and a few + new tests added. - * Updated included popt to the latest vendor drop, version 1.6.4. - (Jos Backus) + - Some new diffs were added to the patches dir, and some accepted + ones were removed. - * Updated config.guess and config.sub to latest versions; this - means rsync should build on more platforms.
