RubyForge: Rainbows!: File Release Notes and Changelog

Notes:
Release Name: 2.0.0

Notes:
Rainbows! is an HTTP server for sleepy Rack applications.  It is based on
Unicorn, but designed to handle applications that expect long
request/response times and/or slow clients.

* http://rainbows.rubyforge.org/
* rainbows-talk@rubyforge.org
* git://git.bogomips.org/rainbows.git

Changes:

This release is targeted at the minority of web applications
that deal heavily with uploads.

Thanks to Unicorn 3.x, we now support HTTP keepalive for
requests with bodies as long as the application consumes them.
Unicorn 3.x also allows disabling the rewindability requirement
of "rack.input" (in violation of the Rack 1.x spec).

The global client_body_max_size may also be applied per-endpoint
using the Rainbows::MaxBody middleware described in:

  http://rainbows.rubyforge.org/Rainbows/MaxBody.html

    tests: depend on Unicorn 3.0.0
    
    Unicorn 3.0.0 is final and released, so we will use it in our
    tests

    simpler keepalive check for synchronous models
    
    Unicorn 3.x includes HttpParser#next? which will reset the
    parser for keepalive requests without extra steps.

    max_body: rewrite wrappers to be safer
    
    To avoid denial-of-service attacks, the wrappers need to
    intercept requests *before* they hit the memory allocator, so we
    need to reimplement the read(all) and gets cases to use
    smaller buffers whenever the application does not specify one.

    max_body: do not enable for RevThread* models
    
    Those already use CapInput, just like the rest of the evented
    Rainbows! world.

    upgrade to Kgio 2.x and Unicorn 3.x
    
    Kgio 2.0.0 has a superior API and less likely to conflict or
    blow up with other applications.  Unicorn 3.x requires Kgio 2.x,
    too.

    test_isolate: depend on newer Unicorn
    
    It allows disabling rewindable input and contains
    simpler code for upload processing.

    reimplement client_max_body_size handlers
    
    This allows the client_max_body_size implementation to not rely
    on Unicorn::TeeInput internals, allowing it to be used with
    Unicorn::StreamInput (or any other (nearly)
    Rack::Lint-compatible input object).

    avoid Errno::EAGAIN, harder
    
    Errno::EAGAIN is still a problem under Ruby 1.9.2, so try harder
    to avoid it and use kgio methods.  Even when 1.9.3 is available,
    kgio will still be faster as exceptions are slower than normal
    return values.

    avoid Kgio::WaitReadable/WaitWritable constants
    
    The underlying symbolic names are easier to type and
    recommended.

    process_client: fix attempted keepalive on HTTP 0.9
    
    The long-term goal is to make the Unicorn API more terse when
    handling keepalive.

    Rainbows! 1.0.0 - internal cleanups
    
    This release is merely a milestone in our evolving internal API.
    Use of kgio may result in performance improvements under Ruby
    1.9.2 with non-blocking I/O-intensive workloads.
    
    The only bugfix is that SIGHUP reloads restores defaults on
    unset settings.  A similar fix is included in Unicorn 2.0.0
    as well.

    tests: avoid race conditions on reload tests
    
    We need to ensure the old worker is really dead before sending
    requests after reloading.

    t0018: wait for old worker to be reaped
    
    On busy machines, old workers may not shutdown quickly
    enough and may still be processing requests.

    rev+event_machine: small cleanups with new parser API
    
    These allow for small reductions in the amount of variables
    we have to manage, more changes coming with later Unicorns.

    HUP reload restores defaults on unset settings
    
    For consistency, changed settings are reset back to
    their default values if they are removed or commented
    out from the config file.
