NEWS for rsync 3.0.8 (26 Mar 2011)
Protocol: 30 (unchanged)
Changes since 3.0.7:

  BUG FIXES:

    - Fixed two buffer-overflow issues: one where a directory path that is
      exactly MAXPATHLEN was not handled correctly, and one handling a
      --backup-dir that is extra extra large.

    - Fixed a data-corruption issue when preserving hard-links without
      preserving file ownership, and doing deletions either before or during
      the transfer (CVE-2011-1097).  This fixes some assert errors in the
      hard-linking code, and some potential failed checksums (via -c) that
      should have matched.

    - Fixed a potential crash when an rsync daemon has a filter/exclude list
      and the transfer is using ACLs or xattrs.

    - Fixed a hang if a really large file is being processed by an rsync that
      can't handle 64-bit numbers.  Rsync will now complain about the file
      being too big and skip it.

    - For devices and special files, we now avoid gathering useless ACL and/or
      xattr information for files that aren't being copied.  (The un-copied
      files are still put into the file list, but there's no need to gather
      data that is not going to be used.)  This ensures that if the user uses
      --no-D, that rsync can't possibly complain about being unable to gather
      extended information from special files that are in the file list (but
      not in the transfer).

    - Properly handle requesting remote filenames that start with a dash.  This
      avoids a potential error where a filename could be interpreted as a
      (usually invalid) option.

    - Fixed a bug in the comparing of upper-case letters in file suffixes for
      --skip-compress.

    - If an rsync daemon has a module configured without a path setting, rsync
      will now disallow access to that module.

    - If the destination arg is an empty string, it will be treated as a
      reference to the current directory (as 2.x used to do).

    - If rsync was compiled with a newer time-setting function (such as
      lutimes), rsync will fall-back to an older function (such as utimes) on a
      system where the newer function is not around.  This helps to make the
      rsync binary more portable in mixed-OS-release situations.

    - Fixed a batch-file writing bug that would not write out the full set of
      compatibility flags that the transfer was using.  This fixes a potential
      protocol problem for a batch file that contains a sender-side I/O error:
      it would have been sent in a way that the batch-reader wasn't expecting.

    - Some improvements to the hard-linking code to ensure that device-number
      hashing is working right, and to supply more information if the hard-link
      code fails.

    - The --inplace code was improved to not search for an impossible checksum
      position.  The quadruple-verbose chunk[N] message will now mention when
      an inplace chunk was handled by a seek rather than a read+write.

    - Improved ACL mask handling, e.g. for Solaris.

    - Fixed a bug that prevented --numeric-ids from disabling the translation
      of user/group IDs for ACLs.

    - Fixed an issue where an xattr and/or ACL transfer that used an alt-dest
      option (e.g. --link-dest) could output an error trying to itemize the
      changes against the alt-dest directory's xattr/ACL info but was instead
      trying to access the not-yet-existing new destination directory.

    - Improved xattr system-error messages to mention the full path to the
      file.

    - The --link-dest checking for identical symlinks now avoids considering
      attribute differences that cannot be changed on the receiver.

    - Avoid trying to read/write xattrs on certain file types for certain OSes.
      Improved configure to set NO_SYMLINK_XATTRS, NO_DEVICE_XATTRS, and/or
      NO_SPECIAL_XATTRS defines in config.h.

    - Improved the unsafe-symlink errors messages.

    - Fixed a bug setting xattrs on new files that aren't user writable.

    - Avoid re-setting xattrs on a hard-linked file w/the same xattrs.

    - Fixed a bug with --fake-super when copying files and dirs that aren't
      user writable.

    - Fixed a bug where a sparse file could have its last sparse block turned
      into a real block when rsync sets the file size (requires ftruncate).

    - If a temp-file name is too long, rsync now avoids truncating the name in
      the middle of adjacent high-bit characters.  This prevents a potential
      filename error if the filesystem doesn't allow a name to contain an
      invalid multi-byte sequence.

    - If a muli-protocol socket connection fails (i.e., when contacting a
      daemon), we now report all the failures, not just the last one.  This
      avoids losing a relevant error (e.g. an IPv4 connection-refused error)
      that happened before the final error (e.g. an IPv6 protocol-not-supported
      error).

    - Generate a transfer error if we try to call chown with a -1 for a uid or
      a gid (which is not settable).

    - Fixed the working of --force when used with --one-file-system.

    - Fix the popt arg parsing so that an option that doesn't take an arg will
      reject an attempt to supply one (can configure --with-included-popt if
      your system's popt library doesn't yet have this fix).

    - A couple minor option tweaks to the support/rrsync script, and also some
      regex changes that make vim highlighting happier.

    - Fixed some issues in the support/mnt-excl script.

    - Various manpage improvements.

  ENHANCEMENTS:

    - Added ".hg/" to the default cvs excludes (see -C & --cvs-exclude).

  DEVELOPER RELATED:

    - Use lchmod() whenever it is available (not just on symlinks).

    - A couple fixes to the socketpair_tcp() routine.

    - Updated the helper scripts in the packaging subdirectory.

    - Renamed configure.in to configure.ac.

    - Fixed configure's checking for iconv routines for newer OS X versions.

    - Fixed the testsuite/xattrs.test script on OS X.
