(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 "make test" bug when build dir is not the source dir. - - INTERNAL: - - * Most of the I/O is now buffered, which results in a pretty - large speedup when running under MS Windows. (Craig Barratt) - - * Optimizations to the name-handling/comparing code have made - some significant reductions in user-CPU time for large file - sets. (Wayne Davison) - - * Some variable-type cleanup that makes the code more consistent. - (Wayne Davison) - - * Reduced memory requirements of hard link preservation. - (J.W. Schultz) - - * Implemented a new algorithm for hard-link handling that speeds - up the code significantly. (J.W. Schultz and Wayne Davison) - - * Got rid of support for protocol versions 17 and 18 (which are - both over 6 years old). (Wayne Davison) - - * More optimal data transmission for --hard-links (protocol 28). - - * More optimal data transmission for --checksum (protocol 28). - - * Less memory used for holding --checksum data. - - * Less memory used per-file in the file list. - - * 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) - - -NEWS for rsync 2.6.0 (1 Jan 2004) -Protocol: 27 (changed) -Changes since 2.5.7: + - Changed the way --progress overwrites its prior output in order to make + it nearly impossible for the progress to get overwritten by an error. 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) - - * 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) - - * The --stats option no longer includes the (debug) malloc summary - unless the verbose option was specified at least twice. - - * 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: - - * 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) - - - 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.] - - - "**/foo" now matches at the base of the transfer (like /foo - does). [Use "/**/foo" to get the old behavior in all versions.] - - - 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. + - Added the --remote-option=OPT (-M OPT) command-line option that is useful + for things like sending a remote --log-file=FILE or --fake-super option. - * Fixed a compression (-z) bug when syncing a mostly-matching file - that contains already-compressed data. (Yasuoka Masahiko and - Wayne Davison) + - Added the --info=FLAGS and --debug=FLAGS options to allow finer-grained + control over what is output. Added an extra type of --progress output + using --info=progress2. - * Fixed a bug in the --backup code that could cause deleted files - to not get backed up. + - Output numbers in 3-digit groups by default (e.g. 1,234,567). (See the + --human-readable option for a way to turn it off.) - * 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). + - Added a "T" (terabyte) category to the --human-readable size suffixes. - * Call setgroups() in a more portable manner. + - Enhanced the --stats output: 1) to mention how many files were created + (protocol >= 28), 2) to mention how many files were deleted (new for + protocol 31), and 3) to follow the file-count, created-count, and + deleted-count with a break-out list of each count by type. - * Improved file-related error messages to better indicate exactly - what pathname failed. (Wayne Davison) + - Added the --usermap/--groupmap/--chown options for manipulating file + ownership during the copy. - * Fixed some bugs in the handling of --delete and --exclude when - using the --relative (-R) option. (Wayne Davison) + - Added the "%C" escape to the log-output handling, which will output the + MD5 checksum of any transferred file, or all files if --checksum was + specified (when protocol 30 or above is in effect). - * 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) + EXTRAS: - * 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) + - Added an "instant-rsyncd" script to the support directory, which makes + it easy to configure a simple rsync daemon in the current directory. - * Added a fix that should give ssh time to restore the tty settings - if the user presses Ctrl-C at an ssh password prompt. + - Added the "mapfrom" and "mapto" scripts to the support directory, which + makes it easier to do user/group mapping in a local transfer based on + passwd/group files from another machine. - INTERNAL: + DEVELOPER RELATED: - * Eliminated vestigial support for old versions that we stopped - supporting. (J.W. Schultz) + - Added more conditional debug output. - * Simplified some of the option-parsing code. (Wayne Davison) + - Really big numbers are now output using our own big-num routine rather + than casting them to a double and using a %.0f conversion. - * Some cleanup made to the exclude code, as well as some new - defines added to enhance readability. (Wayne Davison) + - The pool_alloc library has received some minor improvements in alignment + handling. - * 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) + - Added init_stat_x() function to avoid duplication of acl/xattr init code.
