[augeas-devel] ANNOUNCE: Augeas 0.4.1

I am pleased to announce the release of Augeas 0.4.1; if I were into
codenames this would be the 'Juggling Chainsaws' release.

The two main changes in this release are:
      * when part of the tree corresponding to an entire file is
        removed, the underlying file will be deleted (or moved to
        a .augsave file) when the tree is saved. IOW, when you
        'rm /files/etc/hosts' in augtool and then save, /etc/hosts will
        be removed from the file system
      * the path expression interpreter had a good number of bugs fixed,
        and the grammar for it has been expanded quite a bit:
              * additional boolean operators 'or' and 'and', and
                operators '>', '>=', '<', '<=' for comparing numbers
              * function label() to get the label of the context node,
                e.g. /foo/*[label() != '#comment'] gets all non comment
                nodes under /foo
              * function count() to count the number of nodes in a node
                set, e.g. /foo/*[count(bar) = 0] gets all nodes
                under /foo that don't have a child bar
              * function position() to get the postion of the context
                node, e.g. /foo/*[position() < last() ] selects all
                children of /foo except for the last one

Tarball:          http://augeas.net/download/augeas-0.4.1.tar.gz
GPG signature[1]: http://augeas.net/download/augeas-0.4.1.tar.gz.sig

RPM's for Fedora and EPEL are making their way through the build systems
and will be available shortly from the usual repos.

Detailed news:

  - Remove files when their entire subtree under /files is deleted
  - Various bug fixes and syntax enhancements for path expressions
    (see tests/xpath.tests for details)
  - Evaluate path expressions with multiple predicates correctly
  - Fix incorrect setting of /augeas/events/saved
  - Major cleanup of matching during get; drastically improves
    performance for very large (on the order of 10k lines) config files
  - Small performance improvement in the typechecker
  - Reject invalid character sets like [x-u] during typecheck
  - Build with compile warnings set to 'maximum' instead of 'error', so
    that builds on platforms with broken headers will work out of the box
  - Lens changes/additions
    * Util.stdexcl now excludes .augsave and .augnew files
    * Logrotate: allow 'yearly' schedule, spaces around braces
    * Ntp: fix so that it processes ntp.conf on Fedora 10
    * Services: lens for /etc/services (Raphael Pinson)
    * Xorg: new lens and tests (Raphael Pinson)


[1] To verify the signature, first download both the .sig file and the
corresponding tarball. Then, run a command like this:

  gpg --verify augeas-0.4.1.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver keys.gnupg.net --recv-keys FC6E8A22

and rerun the `gpg --verify' command.
