While the widely-publicized security problem in zlib 1.2.2 did - not affect rsync, another security problem surfaced that affects rsync's - zlib 1.1.4. + - The handling of implied directories when using --relative has changed + to send them as directories (e.g. no implied dir is ever sent as a + symlink). This avoids unexpected behavior and should not adversely + affect most people. If you're one of those rare people who relied + upon having an implied dir be duplicated as a symlink, either specify + --keep-dirlinks or --no-implied-dirs. BUG FIXES: - - The setting of flist->high in clean_flist() was wrong for an empty list. - This could cause flist_find() to crash in certain rare circumstances - (e.g. if just the right directory setup was around when --fuzzy was - combined with --link-dest). + - Fixed the output of -ii when combined with one of the --*-dest options: + it now itemizes all the items, not just the changed ones. - - The outputting of hard-linked files when verbosity was > 1 was not right: - without -i it would output the name of each hard-linked file as though - it had been changed (it now outputs a "is hard linked" message for the - file); with -i it would output all dots for the unchanged attributes of - a hard-link (it now changes those dots to spaces, as is done for other - totally unchanged items). + - Made the output of all file types consistent when using a --*-dest + option. Prior versions used to output too many creation events for + matching items. - - When backing up a changed symlink or device, get rid of any old backup - item so that we don't get an "already exists" error. + - The code that waits for a child pid now handles being interrupted by a + signal. This fixes a problem with the pre-xfer exec function not being + able to get the exit status from the script. - - A couple places that were comparing a local and a remote modification- - time were not honoring the --modify-window option. + - A negated filter rule (with a '!' modifier) no longer loses the negation + when sending the filter rules to the remote rsync. - - Fixed a really old, minor bug that could cause rsync to warn about being - unable to mkdir() a path that ends in "/." because it just created the - directory (required --relative, --no-implied-dirs, a source path that - ended in either a trailing slash or a trailing "/.", and a non-existing - destination dir to tickle the bug in a recent version). + - Fixed a problem with the --out-format (aka --log-format) option %f: it + would output superfluous directory information for a non-daemon rsync. - - 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. + - Fixed a problem with -vv (double --verbose) and --stats when "pushing" + files (which includes local copies). Version 2.6.9 would complete the + copy, but exit with an error when the receiver output its memory stats. - - Rsync now outputs a targeted error if both the source and destination - path appear to be a remote filespecs rather than treating the dest as - a very strange local path and (most likely) generating an error about - non-existent directories. + - If --password-file is used on a non-daemon transfer, rsync now complains + and exits. This should help users figure out that they can't use this + option to control a remote shell's password prompt. + + - Make sure that directory permissions of a newly-created destination + directory are handled right when --perms is left off. + + - The itemized output of a newly-created destination directory is now + output as a creation event, not a change event. + + - Improved --hard-link so that more corner cases are handled correctly + when combined with options such as --link-dest and/or --ignore-existing. + + - The --append option no longer updates a file that has the same size. + + - Fixed a bug when combining --backup and --backup-dir with --inplace: + any missing backup directories are now created. + + - Fixed a bug when using --backup and --inplace with --whole-file or + --read-batch: backup files are actually created now. + + - Starting up an extra copy of an rsync daemon does not delete the pidfile + for the running daemon -- if the pidfile exists, the extra program will + exit with an error. + + - The daemon pidfile is checked and created sooner in the startup sequence. ENHANCEMENTS: - - Added the --append option that makes rsync append data onto files - that are longer on the source than the destination (this includes new - files). + - A new incremental-recursion algorithm is now used when rsync is talking + to another 3.x version. This starts the transfer going more quickly + (before all the files have been found), and requires much less memory. + See the --recursive option in the manpage for some restrictions. + + - Saved memory in the non-incremental-recursion algorithm for typical + option values (usually saving from 21-29 bytes per file). + + - The default --delete algorithm is now --delete-during when talking to a + 3.x rsync. This is a faster scan than using --delete-before (which is + the default when talking to older rsync versions), and is compatible with + the new incremental recursion mode. + + - Rsync now allows multiple remote-source args to be specified rather than + having to rely on a special space-splitting side-effect of the remote- + shell. Additional remote args must specify the same host or have an + empty hostname, as seen here: :file1 ::module/file2. This means that + local use of brace expansion now works: rsync -av host:path/{f1,f2} . + + - Added the --delete-delay option, which is a more efficient way to delete + files at the end of the transfer without needing a separate delete pass. + + - Added the --acls (-A) option to preserve Access Control Lists. This is + an improved version of the prior patch that was available, and it even + supports OS X ACLs. (If you need to have backward compatibility with + old, patched versions of rsync, apply the acls.diff file from the patches + dir.) + + - Added the --xattrs (-X) option to preserver extended attributes. This is + an improved version of the prior patch that was available. (If you need + to have backward compatibility with old, patched versions of rsync, apply + the xattrs.diff file from the patches dir.) + + - Added the --fake-super option that allows a non-super user to preserve + all attributes of a file by using a special extended-attribute idiom. + There is also an analogous "fake super" option for an rsync daemon. + + - Added the --iconv option, which allows rsync to convert filenames from + one character-set to another during the transfer. The default is to make + this feature available as long as your system has iconv_open(). If + compilation fails, specify --disable-iconv to configure, and then + rebuild. If you want rsync to perform character-set conversions by + default, you can specify --enable-iconv=CONVERT_STRING with the default + value for the --iconv option that you wish to use. For example, + --enable-iconv=. is a good choice. See the rsync manpage for an + explanation of the --iconv option's settings. + + - Added the --skip-compress=LIST option to override of the default list of + file suffixes that will not be compressed when using --compress. + + - The daemon's default for "dont compress" was extended to include: + *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg + The matching routine was also optimized to run more quickly. + + - The --max-delete option now outputs a warning if it skipped any file + deletions, including a count of how many deletions were skipped. (Older + versions just silently stopped deleting things.) + + - You may specify --max-delete=0 to a 3.0.0 client to request that it warn + about extraneous files without deleting anything. If you're not sure + what version the client is, you can use the less-obvious --max-delete=-1, + as both old and new versions will treat that as the same request (though + older versions don't warn). + + - The --hard-link option now uses less memory on both the sending and + receiving side for all protocol versions. For protocol 30, the use of a + hashtable on the sending side allows us to more efficiently convey to the + receiver what files are linked together. This reduces the amount of data + sent over the socket by a considerable margin (rather than adding more + data), and limits the in-memory storage of the device+inode information + to just the sending side for the new protocol 30, or to the receiving + side when speaking an older protocol (note that older rsync versions kept + the device+inode information on both sides). + + - The filter rules now support a perishable ("p") modifier that marks rules + that should not have an effect in a directory that is being deleted. e.g. + -f '-p .svn/' would only affect "live" .svn directories. + + - If we get an error setting the time on a symlink, we don't complain about + it anymore (since some operating systems don't support that, and it's not + that important). + + - Protocol 30 now uses MD5 checksums instead of MD4. + + - If a daemon module's "path" value is not an absolute pathname, the code + now makes it absolute internally (making it work properly). + + - Changed the --append option to not checksum the existing data in the + destination file, which speeds up file appending. + + - Added the --append-verify option, which works like the older --append + option (verifying the existing data in the destination file). For + compatibility with older rsync versions, any use of --append that is + talking protocol 29 or older will revert to the --append-verify method. + + - Documented and extended the support for the RSYNC_CONNECT_PROG variable + that can be used to enhance the client side of a daemon connection. + + - Added the --protect-args (-s) option, that tells rsync to send most of + the command-line args at the start of the transfer rather than as args + to the remote-shell command. This protects them from space-splitting, + and only interprets basic wildcard special shell characters (*?[). + + - Improved the dashes and double-quotes in the nroff manpage output. + + - We now support a lot more --no-OPTION override options. + + INTERNAL: + + - The file-list sorting algorithm now uses a sort that keeps any same- + named items in the same order as they were specified. This allows + rsync to always ensure that the first of the duplicates is the one + that will be included in the copy. The new sort was also faster + than the glibc version of qsort() and mergesort() in my testing. + + - Rsync now supports the transfer of 64-bit timestamps (time_t values). + + - Fixed a build problem with older (2.x) versions of gcc. + + - Added some isType() functions that make dealing with signed characters + easier without forcing variables via casts. + + - Changed strcat/strcpy/sprintf function calls to use safer versions. + + - Upgraded the included popt version to 1.10.2 and improved its use of + string-handling functions. - - The configure script now checks for lutimes() and lchmod() so that - rsync can make use of them to update attributes of symlinks (on - systems that support this). + - Added missing prototypes for compatibility functions from the lib dir. - - Made the "max verbosity" setting in the rsyncd.conf file settable on a - per-module basis (which now matches the documentation). + - Configure determines if iconv() has a const arg, allowing us to avoid a + compiler warning. - - 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. + - Made the sending of some numbers more efficient for protocol 30. - - The support/rrsync script has been upgraded to verify the args of options - that take args (instead of rejecting any such options). The script was - also changed to try to be more secure and to fix a problem in the parsing - of a pull operation that has multiple sources. + - Make sure that a daemon process doesn't mind if the client was weird and + omitted the --server option. - - Improved the documentation that explains the difference between a - normal daemon transfer and a daemon-over remote-shell transfer. + - Improved the use of "const" on pointers. - - Some of the diffs supplied in the patches dir were fixed and/or - improved. + - Improved J.W.'s pool_alloc routines to add a way of freeing older + sections of a pool's memory. - BUILD CHANGES: + DEVELOPER RELATED: - - Made configure define NOBODY_USER (currently hard-wired to "nobody") and - NOBODY_GROUP (set to either "nobody" or "nogroup" depending on what we - find in the /etc/group file). + - Rsync is now licensed under the GPLv3 or later. - - Added a test to the test suite, itemized.test, that tests the output of - -i (log-format w/%i) and some double-verbose messages. + - When running the tests, we now put our per-test temp dirs into a sub- + directory named testtmp (which is created, if missing). This allows + someone to symlink the testtmp directory to another filesystem (which is + useful if the build dir's filesystem does not support ACLs and xattrs, + and another file system does). + - Rsync now has a way of handling protocol-version changes during the + development of a new protocol version. This exchange of sub-version + info does not interfere with the {MIN,MAX}_PROTOCOL_VERSION checking + in older versions (since we'd quickly exceed the MAX_PROTOCOL_VERSION + if we incremented the main PROTOCOL_VERSION value for every minor + change during development).
