If you want to - change this, configure like this: "./configure --with-rsh=rsh". + - The itemized output now uses 'S' for a special file instead of + clumping them together with the 'D' for devices. The number of + characters is also different (to remove an unused field). - * 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) + BUG FIXES: - * Length of csum2 is now per-file starting with protocol version - 27. (J.W. Schultz) + - Fixed a really old bug that caused --checksum (-c) to checksum all the + files encountered during the delete scan (ouch). - * 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) + - Made hard-links work with symlinks and devices again. - * The --stats option no longer includes the (debug) malloc summary - unless the verbose option was specified at least twice. + - If a device-file/special-file changes permissions, rsync now updates the + permissions without recreating the file. - * 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 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. - * Various trailing-info sections are now preceded by a newline. + - 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. - BUG FIXES: + - Reject the combination of --inplace and --sparse since the sparse-output + algorithm doesn't work when overwriting existing data. + + - Fixed the directory name in the error that is output when pop_dir() + fails. + + - Really fixed the parsing of a "!" entry in .cvsignore files this time. + + - 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). - * 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) + - If waitpid() fails or the child rsync didn't exit cleanly, we now handle + the exit status properly and generate a better error. - - A pattern with a "**" no longer causes a "*" to match slashes. - For example, with "/*/foo/**", "foo" must be 2 levels deep. + - Fixed some glitches in the double-verbose output when using --copy-dest, + --link-dest, or --compare-dest. - - "**/foo" now matches at the base of the transfer (i.e. /foo). + - Fixed the matching of the dont-compress items (e.g. *.gz) against files + that have a path component containing a slash. + + - If code reading a filter/exclude file an EINTR error, rsync now clears + the error flag on the file handle so it can keep on reading. + + - If --relative is active, the sending side cleans up trailing "/" or "/." + suffixes to avoid triggering a bug in older rsync versions. Also, we now + reject a ".." dir if it would be sent as a relative dir. + + - If a non-directory is in the way of a directory and rsync is run with + --dry-run and --delete, rsync no longer complains about not being + able to opendir() the not-yet present directory. + + - Got rid of the need for --force to be used in some circumstances with + --delete-after (making it consistent with --delete-before/-during). + + ENHANCEMENTS: - - An 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. + - Added the --specials option to tell rsync to copy special files (and does + not require root). The --devices option now affects just character and + block devices (which now matches the documentation). The -D option still + requests both --devices and --specials, and -a still implies -D. - - 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). + - Added the --append option that makes rsync append data onto files + that are longer on the source than the destination (this includes new + files). - * 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) + - Added the --min-size=SIZE option to exclude small files from the + transfer. - * 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 the --compress-level option to allow you to set how aggressive + rsync's compression should be (this option implies --compress). - * 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) + - 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). - * 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) + - The options --human-readable (-h) and --si change the output of the + --stats and the end-of-run summary to be easier to read. - * Keep tmp names from overflowing MAXPATHLEN. + - If lutimes() and/or lchmod() are around, use them to allow the + preservation of attributes on symlinks. - * Make --link-dest honor the absence of -p, -o, and -g. + - The --link-dest option now affects symlinks and devices (when + possible). - * Made rsync treat a trailing slash in the destination in a more - consistent manner. + - Improved the output of hard-linked and copied files when using + --link-dest, --copy-dest, or --compare-dest. - * Fixed file I/O error detection. (John Van Essen) + - 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.) - * 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. + - 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). - * Print heap statistics when verbose >= 2 instead of when >= 1. + - 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. - * Fixed a compression (-z) bug when syncing a mostly-matching file - that contains already-compressed data. (Yasuoka Masahiko and - Wayne Davison) + - Added the --chmod=MODE option that allows the destination permissions + to be changed from the source permissions. E.g. --chmod=g+w,o-rwx - * Fixed a bug in the --backup code that could cause deleted files - to not get backed up. + - Added the "incoming chmod" daemon option to allow a module to specify + what permissions changes should be applied to all files copied to the + daemon. - * 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). + - Allow the --temp-dir option to be specified when starting a daemon, + which sets the default temporary directory for incoming files. - * Call setgroups() in a more portable manner. + - If --delete is combined with --dirs without --recursive, rsync will + now delete in any directory whose content is being synchronized. - * Improved file-related error messages to better indicate exactly - what pathname failed. (Wayne Davison) + - 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 some bugs in the handling of --delete and --exclude when - using the --relative (-R) option. (Wayne Davison) + - 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 the fifth file + to be transferred, and we still need to check 8383 more files out of + a total of 9999. - * 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) + - The include/exclude code now allows a dir/*** directive (with 3 + trailing stars) to match both the dir itself as well as all the + content below the dir (dir/** would not match the dir). - * Detect and report when open or opendir succeed but read and - readdir fail caused by network filesystems issues and truncated - files. (David Norwood, Michael Brown, J.W. Schultz) + - Added the --prune-empty-dirs (-m) option that makes the receiving + rsync discard empty chains of directories from the file-list. This + makes it easier to selectively copy files from a source hierarchy and + end up with just the directories needed to hold the resulting files. - * 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 the --itemize-changes (-i) option is repeated, rsync now includes + unchanged files in the itemized output (similar to -vv, but without + all the other verbose messages that can get in the way). Of course, + the client must be version 2.6.7 for this to work, but the remote + rsync only needs to be 2.6.7 if you're pushing files. + + - Added the --super option to make the receiver always attempt super- + user activities. This is useful for systems that allow things such + as devices to be created or ownership to be set without being UID 0, + and is also useful for someone who wants to ensure that errors will + be output if the receiving rsync isn't being run as root. + + - Added the --sockopts option for those few who want to customize the + TCP options used to contact a daemon rsync. + + - Added a way for the --temp-dir option to be combined with a partial-dir + setting that lets rsync avoid non-atomic updates (for those times when + --temp-dir is not being used because space is tight). + + - Some minor documentation improvements. + + - Updated some diffs in the patches dir. INTERNAL: - * Eliminated vestigial support for old versions that we stopped - supporting. (J.W. Schultz) + - Some buffer sizes were expanded a bit, particularly on systems where + MAXPATHLEN is overly small (e.g. cygwin). + + - If io_printf() tries to format more data than fits in the buffer, exit + with an error instead of transmitting a truncated buffer. + + - If a va_copy macro is defined, lib/snprintf.c will use it when defining + the VA_COPY macro. + + - Reduced the amount of stack memory needed for each level of directory + recursion by nearly MAXPATHLEN bytes. + + - The wildmatch function was extended to allow an array of strings to + be supplied as the string to match. This allows the exclude code to + do less string copying. + + - Got rid of the safe_fname() function (and all the myriad calls) and + replaced it with a new function in the log.c code that filters all + the output going to the terminal. + + - Unified the f_name() and the f_name_to() functions. - * 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) + - The testsuite now sets HOME so that it won't be affecting by a file + such as ~/.popt.
