RubyForge: Rainbows!: File Release Notes and Changelog

Notes:
Release Name: 3.4.0

Notes:
Rainbows 3.4.0 - minor updates and fixes

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://bogomips.org/rainbows.git

Changes:

SIGQUIT (graceful shutdown) now drops idle keepalive clients for
the concurrency models where maintaining an idle client is
relatively inexpensive: Coolio, CoolioThreadPool,
CoolioThreadSpawn, Epoll, EventMachine, XEpoll,
XEpollThreadPool, XEpollThreadSpawn.

Kgio.autopush now works properly for all multi-threaded
concurrency models (if you're using :tcp_nopush).

    use and recommend sleepy_penguin 3.0.1
    
    It's better under 1.9.3 (sleepy_penguin 3.0.1 was bogus)

    t0044: increase test reliability

    try_defer: enable documentation
    
    It should hopefully give this more visibility even though it's
    an internal feature.

    xepoll_thread_pool/client: improve autopush support
    
    We need to trigger a recv() to uncork the response.
    This won't affect fairness (much) since all recv()s
    are non-blocking and a successful header parse will
    put us in the back of the queue.

    .gitignore: add tags/TAGS files
    
    Some folks use them.

    add tests for Kgio autopush on Linux
    
    We can support it fully for a subset of concurrency models where
    we have full control over buffering and HTTP/1.1 keepalive
    clients.

    add test for SIGQUIT disconnect
    
    This will only be supported for certain concurency models, but
    it's probably good enough.

    event_machine: disconnect idle clients at on SIGQUIT
    
    Since it's cheap to maintain keepalive clients with EM, we need
    a way of disconnecting them in a timely fashion on rare SIGQUIT
    events.

    client: use kgio_write across the board
    
    This should enable Kgio "autopush" support for ThreadSpawn,
    ThreadPool, XEpollThreadSpawn, and XEpollThreadPool.
    
    (still needs tests)

    coolio* + *epoll*: drop keepalive clients on SIGQUIT
    
    In concurrency models long keepalive times are cheap (and thus
    more likely to be used), this allows Rainbows! to gracefully
    shut down more quickly.

    epoll/xepoll: more consistent client implementations
    
    There's less logic in the server this way and easier
    to potentially share code this way.

    doc: recommend io_splice 4.1.1 or later
    
    io_splice 4.1.1 works around issues with socket
    buffers filling up pipe buffers on blocking splice.
    
    See http://lkml.org/lkml/2009/1/13/478 for a better
    explanation.
