(Wayne Davison) - - * Fixed a bug in the handling of -H (hard-links) that might - cause the expanded PATH/NAME value of the current item to - get overwritten (due to an expanded-name caching bug). - (Wayne Davison) - - * Keep per-file track of the sending of literal data with - --partial so that an interrupted transfer doesn't keep a - shorter temp file when no new data has been transfered over - the wire. (Wayne Davison) - - * Fixed a byte-order problem in --batch-mode on big-endian - machines. (Jay Fenlason) - - * Fixed configure bug when running "./configure --disable-ipv6". - (Wayne Davison) + - Fixed a crash bug that might appear when --delete was used and + multiple source directories were specified. - * Fixed "make test" bug when build dir is not the source dir. + - Fixed the 32-bit truncation of the file length when generating the + checksums. - * When using --cvs-exclude, the exclude items we get from a - directory's .cvsignore file once again only affect that one - directory (and not all following directories too). + - The --backup code no longer attempts to create some directories + over and over again (generating warnings along the way). - INTERNAL: - - * Most of the I/O is now buffered, which results in a pretty - large speedup when running under MS Windows. (Craig Barratt) + - 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. - * Optimizations to the name-handling/comparing code have made - some significant reductions in user-CPU time for large file - sets. (Wayne Davison) + - 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.) - * Some variable-type cleanup that makes the code more consistent. - (Wayne Davison) + - 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). - * Reduced memory requirements of hard link preservation. - (J.W. Schultz) + - Fixed an age-old crash problem with --read-batch on a local copy + (rsync was improperly assuming --whole-file for the local copy). - * Implemented a new algorithm for hard-link handling that speeds - up the code significantly. (J.W. Schultz and Wayne Davison) + - 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 support for protocol versions 17 and 18 (which are - both over 6 years old). (Wayne Davison) + - Got rid of a potential hang in the receiver when near the end of a + phase. - * More optimal data transmission for --hard-links (protocol 28). + - When using --backup without a --backup-dir, rsync no longer preserves + the modify time on directories. This avoids confusing NFS. - * More optimal data transmission for --checksum (protocol 28). + - 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". - * Less memory used for holding --checksum data. + - 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). - * Less memory used per-file in the file list. + - 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). - * The 2 pipes used between the receiver and generator processes - (which are forked on the same machine) were reduced to 1 pipe and - the protocol improved so that (1) it is now impossible to have the - "redo" pipe fill up and hang rsync, and (2) trailing messages from - the receiver don't get lost on their way to through generator over - to the sender. (Wayne Davison) + - Fixed a bug in the daemon authentication code when using one of the + batch-processing options. - -NEWS for rsync 2.6.0 (1 Jan 2004) -Protocol: 27 (changed) -Changes since 2.5.7: + - 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). ENHANCEMENTS: - * "ssh" is now the default remote shell for rsync. If you want to - change this, configure like this: "./configure --with-rsh=rsh". - - * Added --files-from, --no-relative, --no-implied-dirs, and --from0. - Note that --from0 affects the line-ending character for all the - files read by the --*-from options. (Wayne Davison) - - * Length of csum2 is now per-file starting with protocol version - 27. (J.W. Schultz) + - 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. - * Per-file dynamic block size is now sqrt(file length). The - per-file checksum size is determined according to an algorithm - 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) + - Added the "write only" option to the daemon's config file. - * The --stats option no longer includes the (debug) malloc summary - unless the verbose option was specified at least twice. + - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) + and documented all these options in the man page. - * Added a new error/warning code for when files vanish from the - sending side. Made vanished source files not interfere with the - file-deletion pass when --delete-after was specified. - - * Various trailing-info sections are now preceded by a newline. - - BUG FIXES: + - Improved the handling of the --bwlimit option so that it's less + bursty, more accurate, and works properly over a larger range of + values. - * Fixed several exclude/include matching bugs when using wild-cards. - This has a several user-visible effects, all of which make the - matching more consistent and intuitive. This should hopefully not - cause anyone problems since it makes the matching work more like - what people are expecting. (Wayne Davison) + - 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. - - A pattern with a "**" no longer causes a "*" to match slashes. - For example, with "/*/foo/**", "foo" must be 2 levels deep. - [If your string has BOTH "*" and "**" wildcards, changing the - "*" wildcards to "**" will provide the old behavior in all - versions.] + - Added the --checksum-seed=N option for advanced users. - - "**/foo" now matches at the base of the transfer (like /foo - does). [Use "/**/foo" to get the old behavior in all versions.] + - 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. (Chris Shoemaker) - - A non-anchored wildcard term floats to match beyond the base of - the transfer. E.g. "CVS/R*" matches at the end of the path, - just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*" - to get the old behavior in all versions.] - - - Including a "**" in the match term causes it to be matched - against the entire path, not just the name portion, even if - there aren't any interior slashes in the term. E.g. "foo**bar" - would exclude "/path/foo-bar" (just like before) as well as - "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the - old behavior in all versions.] - - * The exclude list specified in the daemon's config file is now - properly applied to the pulled items no matter how deep the - user's file-args are in the source tree. (Wayne Davison) - - * 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) - - * 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) - - * Keep tmp names from overflowing MAXPATHLEN. - - * Make --link-dest honor the absence of -p, -o, and -g. - - * Made rsync treat a trailing slash in the destination in a more - consistent manner. - - * Fixed file I/O error detection. (John Van Essen) - - * Fixed bogus "malformed address {hostname}" message in rsyncd log - when checking IP address against hostnames from "hosts allow" - and "hosts deny" parameters in config file. - - * Print heap statistics when verbose >= 2 instead of when >= 1. + INTERNAL: - * Fixed a compression (-z) bug when syncing a mostly-matching file - that contains already-compressed data. (Yasuoka Masahiko and - Wayne Davison) + - Some cleanup in the exclude code has saved some per-exclude memory + and made the code easier to maintain. - * Fixed a bug in the --backup code that could cause deleted files - to not get backed up. + - Improved the argv-overflow checking for a remote command that has + a lot of args. - * When the backup code makes new directories, create them with mode - 0700 instead of 0755 (since the directory permissions in the - backup tree are not yet copied from the main tree). + - Use rsyserr() in the various places that were still calling + rprintf() with strerror() as an arg. - * Call setgroups() in a more portable manner. + - 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). - * Improved file-related error messages to better indicate exactly - what pathname failed. (Wayne Davison) + - Optimized away a loop in hash_search(). - * Fixed some bugs in the handling of --delete and --exclude when - using the --relative (-R) option. (Wayne Davison) + BUILD CHANGES: - * Fixed bug that prevented regular files from replacing - special files and caused a directory in --link-dest or - --compare-dest to block the creation of a file with the - same path. A directory still cannot be replaced by a - regular file unless --delete specified. (J.W. Schultz) + - Added a "gen" target to rebuild most of the generated files, + including configure, config.h.in, the man pages, and proto.h. - * Detect and report when open or opendir succeed but read and - readdir fail caused by network filesystem issues and truncated - files. (David Norwood, Michael Brown, J.W. Schultz) + - 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). - * Added a fix that should give ssh time to restore the tty settings - if the user presses Ctrl-C at an ssh password prompt. + - 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. - INTERNAL: + - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined. - * Eliminated vestigial support for old versions that we stopped - supporting. (J.W. Schultz) + DEVELOPER RELATED: - * Simplified some of the option-parsing code. (Wayne Davison) + - The scripts in the testsuite dir were cleaned up a bit. - * Some cleanup made to the exclude code, as well as some new - defines added to enhance readability. (Wayne Davison) + - Some new diffs were added to the patches dir, and some accepted + ones were removed. - * Changed the protocol-version code so that it can interact at a - lower protocol level than the maximum supported by both sides. - Added an undocumented option, --protocol=N, to force the value - we advertise to the other side (primarily for testing purposes). - (Wayne Davison)
