(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) - - * We now reset the "new data has been sent" flag at the start - of each file we send. This makes sure that an interrupted - transfer with the --partial option set doesn't keep a shorter - temp file than the current basis file when no new data has been - transfered over the wire for that file. (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. - - * 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). - - * When transferring a file that has group 0 with -g specified - (typically via -a) and not enough privs to retain the group, - rsync no longer complains about "chown" failing. - - * When specifying the USER@HOST: prefix for a file, the USER - part can now contain an '@', if needed (i.e. the last '@' - is used to find the HOST, not the first). - - * Fixed some bugs in the handling of group IDs for non-root - users: (1) It properly handles a group that the sender didn't - have a name for (it would previously skip changing the group - on any files in that group). (2) If --numeric-ids is used, - rsync no longer attempts to set groups that the user doesn't - have the permission to set. - - 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) - - * The --hard-link option now uses the first existing file in the - group of linked files as the basis for the transfer. This - prevents the sub-optimal transfer of a file's data when a new - hardlink is added on the sending side and it sorts alphabetically - earlier in the list than the files that are already present on the - receiving side. - - * Got rid of support for protocol versions 17 and 18 (which are - both over 6 years old). (Wayne Davison) + - Fixed a really old bug that caused --checksum (-c) to checksum all the + files encountered during the delete scan (ouch). - * More optimal data transmission for --hard-links (protocol 28). + - Made hard-links work with symlinks and devices again. - * More optimal data transmission for --checksum (protocol 28). + - If a device-file/special-file changes permissions, rsync now updates the + permissions without recreating the file. - * Less memory is used when --checksum is specified. + - If the user specifies a remote-host for both the source and destination, + we now output a syntax error rather than trying to open the destination + hostspec as a filename. - * Less memory is used in the file list (a per-file savings). + - When --inplace creates a new destination file, rsync now creates it with + permissions 0600 instead of 0000 -- this makes restarting possible when + the transfer gets interrupted in the middle of sending a new file. - * Changed hardlink info and file_struct + strings to use - allocation pools. This reduces memory use for large - filesets and permits freeing memory to the OS. (J.W. Schultz) + - Reject the combination of --inplace and --sparse since the sparse-output + algorithm doesn't work when overwriting existing data. - * 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 through - the generator over to the sender (the latter mainly affected - hard-link messages). (Wayne Davison) + - Fixed the directory name in the error that is output when pop_dir() + fails. - * The reading & writing of the file list in batch-mode is now - handled by the same code that sends & receives the list over - the wire. This makes it much easier to maintain. + - Really fixed the parsing of a "!" entry in .cvsignore files this time. - * Optimized the -x (--one-file-system) flag's handling of any - mount-point directories we encounter (it no longer scans the - contents of the mount-point dirs, just to throw away the data). + - If the generator gets a stat() error on a file, output it (this used to + require at least -vv for the error to be seen). - * Improved the internal uid/gid code to be more portable and - a little more optimized. + - If waitpid() fails or the child rsync didn't exit cleanly, we now handle + the exit status properly and generate a better error. - -NEWS for rsync 2.6.0 (1 Jan 2004) -Protocol: 27 (changed) -Changes since 2.5.7: + - Fixed some glitches in the double-verbose output when using --copy-dest, + --link-dest, or --compare-dest. ENHANCEMENTS: - * "ssh" is now the default remote shell for rsync. If you want to - change this, configure like this: "./configure --with-rsh=rsh". + - Added the --append option that makes rsync append data onto files + that are longer on the source than the destination (this includes new + files). - * 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) + - Added the --min-size=SIZE option to exclude small files from the + transfer. - * Length of csum2 is now per-file starting with protocol version - 27. (J.W. Schultz) + - Added the --compress-level option to allow you to set how aggressive + rsync's compression should be (this option implies --compress). - * 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) + - Enhanced the parsing of the SIZE value for --min-size and --max-size + to allow easy entry of multiples of 1000 (instead of just multiples + of 1024) and off-by-one values too (e.g. --max-size=8mb-1). - * The --stats option no longer includes the (debug) malloc summary - unless the verbose option was specified at least twice. + - The options --human-readable (-h) and --si change the output of the + --stats and the end-of-run summary to be easier to read. - * 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. + - If lutimes() and/or lchmod() are around, use them to allow the + preservation of attributes on symlinks. - * Various trailing-info sections are now preceded by a newline. + - The --link-dest option now affects symlinks and devices (when + possible). - 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) + - Improved the output of hard-linked and copied files when using + --link-dest, --copy-dest, or --compare-dest. - * 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) + - Added two config items to the rsyncd.conf parsing: "pre-xfer exec" + and "post-xfer exec". These allow a command to be specified on a + per-module basis that will be run before and/or after a daemon-mode + transfer. (See the manpage for a list of the environment variables + that are set with information about the transfer.) - * 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) + - When using the --relative option, you can now insert a dot dir in + the source path to indicate where the replication of the source dirs + should start. For example, if you specify a source path of + rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only + replicate the "baz/dir" part of the source path (note: a trailing + dot dir is unaffected unless it also has a trailing slash). - * 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) + - Added some new --no-FOO options that make it easier to override + unwanted implied or default options. For example, "-a --no-o" (aka + "--archive --no-owner") can be used to turn off the preservation of + file ownership that is implied by -a. - * Keep tmp names from overflowing MAXPATHLEN. + - Added the --chmod=MODE option that allows the destination permissions + to be changed from the source permissions. E.g. --chmod=g+w,o-rwx - * Make --link-dest honor the absence of -p, -o, and -g. + - Allow the --temp-dir option to be specified when starting a daemon, + which sets the default temporary directory for incoming files. - * Made rsync treat a trailing slash in the destination in a more - consistent manner. + - If --delete is combined with --dirs without --recursive, rsync will + now delete in any directory whose content is being synchronized. - * Fixed file I/O error detection. (John Van Essen) + - If --backup is combined with --delete without --backup-dir (and + without --delete-excluded), we add a protect filter-rule to ensure + that files with the backup suffix are not deleted. - * 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. + - The file-count stats that are output by --progress were improved to + better indicate what the numbers mean. For instance, the output: + "(xfer#5, to-check=8383/9999)" indicates that this was transferred + file #5, and we still need to check 8383 files out of 9999 total. - * Print heap statistics when verbose >= 2 instead of when >= 1. + - Some minor documentation improvements. - * Fixed a compression (-z) bug when syncing a mostly-matching file - that contains already-compressed data. (Yasuoka Masahiko and - Wayne Davison) + - Updated some diffs in the patches dir. - * Fixed a bug in the --backup code that could cause deleted files - to not get backed up. - - * 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). - - * Call setgroups() in a more portable manner. - - * Improved file-related error messages to better indicate exactly - what pathname failed. (Wayne Davison) - - * Fixed some bugs in the handling of --delete and --exclude when - using the --relative (-R) option. (Wayne Davison) - - * 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) + INTERNAL: - * 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) + - Some buffer sizes were expanded a bit, particularly on systems where + MAXPATHLEN is overly small (e.g. cygwin). - * Added a fix that should give ssh time to restore the tty settings - if the user presses Ctrl-C at an ssh password prompt. + - If io_printf() tries to format more data than fits in the buffer, exit + with an error instead of transmitting a truncated buffer. - INTERNAL: + - If a va_copy macro is defined, lib/snprintf.c will use it when defining + the VA_COPY macro. - * Eliminated vestigial support for old versions that we stopped - supporting. (J.W. Schultz) + - Reduced the amount of stack memory needed for each level of directory + recursion by nearly MAXPATHLEN bytes. - * Simplified some of the option-parsing code. (Wayne Davison) + DEVELOPER RELATED: - * Some cleanup made to the exclude code, as well as some new - defines added to enhance readability. (Wayne Davison) + - Several diffs in the patches dir now use the proper --enable-FOO + configure option instead of --with-FOO to turn on the inclusion of + the newly patched feature. - * 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)
