See the - --human-readable option for a way to turn it off. See also the daemon's - "log format" parameter and related command-line options (including - --out-format) for a modifier that can be used to request digit-grouping - or human-readable output in log escapes. (Note that log output is - unchanged by default.) + - Make sure that all transferred files use only path names from inside the + transfer. This makes it impossible for a malicious sender to try to make + the receiver use an unsafe destination path for a transferred file, such + as a just-sent symlink. - - The --list-only option is now affected by the --human-readable setting. - It will display digit groupings by default, and unit suffixes if higher - levels of readability are requested. Also, the column width for the size - output has increased from 11 to 14 characters when human readability is - enabled. Use --no-h to get the old-style output and column size. - - - The output of the --progress option has changed: the string "xfer" was - shortened to "xfr", and the string "to-check" was shortened to "to-chk", - both designed to make room for the (by default) wider display of file - size numbers without making the total line-length longer. Also, when - incremental recursion is enabled, the string "ir-chk" will be used - instead of "to-chk" up until the incremental-recursion scan is done, - letting you know that the value to check and the total value will still - be increasing as new files are found. - - - Enhanced the --stats output: 1) to mention how many files were created - (protocol >= 28), 2) to mention how many files were deleted (a new line - for protocol 31, but only output when --delete is in effect), and 3) to - follow the file-count, created-count, and deleted-count with a subcount - list that shows the counts by type. The wording of the transferred count - has also changed so that it is clearer that it is only a count of regular - files. - BUG FIXES: - - Fixed a bug in the iconv code when EINVAL or EILSEQ is returned with a - full output buffer. + - Change the checksum seed order in the per-block checksums. This prevents + someone from trying to create checksum blocks that match in sum but not + content. + - Fixed a with the per-dir filter files (using -FF) that could trigger an + assert failure. + - Only skip set_modtime() on a transferred file if the time is exactly + right. + - Don't create an empty backup dir for a transferred file that doesn't + exist yet. + - Fixed a bug where --link-dest and --xattrs could cause rsync to exit if + a filename had a matching dir of the same name in the alt-dest area. + - Allow more than 32 group IDs per user in the daemon's gid=LIST config. + - Fix the logging of %b & %c via --log-file (daemon logging was already + correct, as was --out-format='%b/%c'). + - Fix erroneous acceptance of --info=5 & --debug=5 (an empty flag name is + not valid). - - Fixed some rare bugs in --iconv processing that might cause a multibyte - character to get translated incorrectly. - - - Fixed a bogus "vanished file" error if some files were specified with - "./" prefixes and others were not. - - - Fixed a bug in --sparse where an extra gap could get inserted after a - partial write. - - - Changed the way --progress overwrites its prior output in order to make - it nearly impossible for the progress to get overwritten by an error. - - - Improved the propagation of abnormal-exit error messages. This should - help the client side to receive errors from the server when it is exiting - abnormally, and should also avoid dying with an "connection unexpectedly - closed" exit when the closed connection is really expected. - - - The sender now checks each file it plans to remove to ensure that it - hasn't changed from the first stat's info. This helps to avoid losing - file data when the user is not using the option in a safe manner. - - - Fixed a data-duplication bug in the compress option that made compression - less efficient. This improves protocol 31 onward, while behaving in a - compatible (buggy) manner with older rsync protocols. - - - When creating a temp-file, rsync is now a bit smarter about it dot-char - choices, which can fix a problem on OS X with names that start with "..". - - - Rsync now sets a cleanup flag for --inplace and --append transfers that - will flush the write buffer if the transfer aborts. This ensures that - more received data gets written out to the disk on an aborted transfer - (which is quite helpful on a slow, flaky connection). - - - The reads that map_ptr() now does are aligned on 1K boundaries. This - helps some filesystems and/or files that don't like unaligned reads. - - - Fix an issue in the msleep() function if time jumps backwards. - - - Fix daemon-server module-name splitting bug where an arg would get split - even if --protect-args was used. - ENHANCEMENTS: - - 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. + - Added "(DRY RUN)" info to the --debug=exit output line. + - Use usleep() for our msleep() function if it is available. + - Added a few extra long-option names to rrsync script, which will make + BackupPC happier. + - Made configure choose to use linux xattrs on netbsd (rather than not + supporting xattrs). + - Added -wo (write-only) option to rrsync support script. + - Misc. manpage tweaks. - - 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. - - - The --msgs2stderr option can help with debugging rsync by allowing the - debug messages to get output to stderr rather than travel via the socket - protocol. - - - Added the --delete-missing-args and --ignore-missing-args options to - either delete or ignore user-specified files on the receiver that are - missing on the sender (normally the absence of user-specified files - generates an error). - - - Added a "T" (terabyte) category to the --human-readable size suffixes. - - - Added the --usermap/--groupmap/--chown options for manipulating file - ownership during the copy. - - - 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). - - - Added the "reverse lookup" parameter to the rsync daemon config file to - allow reverse-DNS lookups to be disabled. - - - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can - be disabled via "forward lookup" parameter (defaults to enabled). - - - Added a way for more than one group to be specified in the daemon's - config file, including a way to specify that you want all of the - specified user's groups without having to name them. Also changed the - daemon to complain about an inability to set explicitly-specified uid/gid - values, even when not run by a super-user. - - - The daemon now tries to send the user the error messages from the - pre-xfer exec script when it fails. - - - Improved the use of alt-dest options into an existing hierarchy of files: - If a match is found in an alt-dir, it takes precedence over an existing - file. (We'll need to wait for a future version before attribute-changes - on otherwise unchanged files are safe when using an existing hierarchy.) - - - Added per-user authorization options and group-authorization support to - the daemon's "auth users" parameter. - - - Added a way to reference environment variables in a daemon's config file - (using %VAR% references). - - - When replacing a non-dir with a symlink/hard-link/device/special-file, - the update should now be done in an atomic manner. - - - Avoid re-sending xattr info for hard-linked files w/the same xattrs - (protocol 31). - - - The backup code was improved to use better logic maintaining the backup - directory hierarchy. Also, when a file is being backed up, rsync tries - to hard-link it into place so that the upcoming replacement of the - destination file will be atomic (for the normal, non-inplace logic). - - - Added the ability to synchronize nano-second modified times. - - - Added a few more default suffixes for the "dont compress" settings. - - - Added the checking of the RSYNC_PROTECT_ARGS environment variable to allow - the default for the --protect-args command-line option to be overridden. - - - Added the --preallocate command-line option. - - - Allow --password-file=- to read the password from stdin (filename "-"). - - - Rsync now comes packaged with an rsync-ssl helper script that can be - used to contact a remote rsync daemon using a piped-stunnel command. - It also includes an stunnel config file to run the server side to - support ssl daemon connections. See the packaging/lsb/rsync.spec - file for one way to package the resulting files. (Suggestions for - how to make this even easier to install & use are welcomed.) - - - Improved the speed of some --inplace updates when there are lots of - identical checksum blocks that end up being unusable. - - - Added the --outbuf=N|L|B option for choosing the output buffering. - - - Repeating the --fuzzy option now causes the code to look for fuzzy - matches inside alt-dest directories too. - - - The --chmod option now supports numeric modes, e.g. --chmod=644,D755 - - - Added some Solaris xattr code. - - - Made an rsync daemon (the listening process) exit with a 0 status when - it was signaled to die. This helps launchd. - - - Improved the RSYNC_* environment variables for the pre-xfer exec script: - when a daemon is sent multiple request args, they are now joined into a - single return value (separated by spaces) so that the RSYNC_REQUEST - environment variable is accurate for any "pre-xfer exec". The values in - RSYNC_ARG# vars are no longer truncated at the "." arg (prior to the - request dirs/files), so that all the requested values are also listed - (separately) in RSYNC_ARG# variables. - - EXTRAS: - - - Added an "instant-rsyncd" script to the support directory, which makes - it easy to configure a simple rsync daemon in the current directory. - - - 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. - - - There's a new, improved version of the lsh script in the support dir: - it's written in perl and supports -u without resorting to using sudo - (when run as root). The old shell version is now named lsh.sh. - - - There is a helper script named rsync-slash-strip in the support directory - for anyone that wants to change the way rsync handles args with trailing - slashes. (e.g. arg/ would get stripped to arg while arg/. would turn into - arg/). - - INTERNAL: - - - The I/O code was rewritten to be simpler and do bigger buffered reads - over the socket. The I/O between the receiver and the generator was - changed to be standard multiplexed-I/O (like that over the socket). - - - The sender tries to use any dead time while the generator is looking for - files to transfer in order to do sender-side directory scanning in a more - parallel manner. - - - A daemon can now inform a client about a daemon-configured timeout value - so that the client can assist in the keep-alive activity (protocol 31). - - - The filter code received some refactoring to make it more extendible, to - read better, and do better sanity checking. - - - Really big numbers are now output using our own big-num routine rather - than casting them to a double and using a %.0f conversion. - - - The pool_alloc library has received some minor improvements in alignment - handling. - - - Added init_stat_x() function to avoid duplication of acl/xattr init code. - - - The included zlib was upgraded from 1.2.3 to 1.2.8. - - - Rsync can now be compiled to use an unmodified zlib library instead of - the tweaked one that is included with rsync. This will eventually - become the default, at which point we'll start the countdown to removing - the included zlib. Until then, feel free to configure using: - - ./configure --with-included-zlib=no - DEVELOPER RELATED: - - Added more conditional debug output. - - - Fixed some build issues for android and minix. + - Fixed a bug with the Makefile's use of INSTALL_STRIP. + - Improve a test in the suite that could get an erroneous timestamp error. + - Tweaks for newer versions of git in the packaging tools. + - Improved the m4 generation rules and some autoconf idioms.
