NEWS for rsync 3.1.0 (28 Sep 2013)NEWS for rsync 3.1.2 (21 Dec 2015)
Protocol: 31 (changed)Protocol: 31 (unchanged)
Changes since 3.0.9:Changes since 3.1.1:
   
  OUTPUT CHANGES:  SECURITY FIXES:
   
    - Output numbers in 3-digit groups by default (e.g. 1,234,567).  See the    - Make sure that all transferred files use only path names from inside the
      --human-readable option for a way to turn it off.  See also the daemon's      transfer.  This makes it impossible for a malicious sender to try to make
      "log format" parameter and related command-line options (including      the receiver use an unsafe destination path for a transferred file, such
      --out-format) for a modifier that can be used to request digit-grouping      as a just-sent symlink.
      or human-readable output in log escapes. (Note that log output is 
      unchanged by default.) 
   
     - 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:    BUG FIXES:
   
    - Fixed a bug in the iconv code when EINVAL or EILSEQ is returned with a    - Change the checksum seed order in the per-block checksums.  This prevents
      full output buffer.      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:    ENHANCEMENTS:
   
    - Added the --remote-option=OPT (-M OPT) command-line option that is useful    - Added "(DRY RUN)" info to the --debug=exit output line.
      for things like sending a remote --log-file=FILE or --fake-super option.    - 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:    DEVELOPER RELATED:
   
    - Added more conditional debug output.    - Fixed a bug with the Makefile's use of INSTALL_STRIP.
    - Improve a test in the suite that could get an erroneous timestamp error.
    - Fixed some build issues for android and minix.    - Tweaks for newer versions of git in the packaging tools.
     - Improved the m4 generation rules and some autoconf idioms.
