Rack-robustness 1.1.0

Hi all!

rack-robustness 1.1.0 is out, it provides the rescue/ensure clause of
your
rack stack.

== CHANGELOG

1.1.0 / 2013-04-16

  • Fixed catching of non standard errors (e.g. SecurityError)

  • Global headers are now correctly overrided by specific per-exception
    headers

  • Renamed #on as #rescue for better capturing semantics of on
    blocks
    (now an alias).

  • Added last resort exception handling if an error occurs during
    exception
    handling itself.
    In no_catch_all mode, the exception is simply reraised; otherwise a
    default 500 error
    is returned with a safe message.

  • Added a shortcut form for #rescue clauses allowing values directly,
    e.g.,

      use Rack::Robustness do |g|
    g.rescue(SecurityError, 403)
  end

  • Added suppport for ensure clause(s), always called after rescue
    blocks

  • Rack’s env is now available in all error handling blocks, e.g.,

      use Rack::Robustness do |g|
    g.status{|ex| ... env ... }
    g.body  {|ex| ... env ... }
    g.rescue(SecurityError){|ex| ... env ... }
    g.ensure{|ex| ... env ... }
  end

  • Similarly, Rack::Robustness now internally uses instances of
    Rack::Request and Rack::Response; request and response are available
    in
    all blocks. The specific Response
    object to use can be built using the response DSL method, e.g.,

      use Rack::Robustness do |g|
    g.response{|ex| MyOwnRackResponse.new }
  end

  • Rack::Robustness may now be subclassed as an alternative to inline
    use,
    e.g.

      class Shield < Rack::Robustness
    self.body  {|ex| ... }
    self.rescue(SecurityError){|ex| ... }
    ...
  end

  # in Rack-based configuration
  use Shield

Have a nice day!
