RubyForge: Rainbows!: File Release Notes and Changelog

Notes:
Release Name: 0.91.0

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.  For Rack applications not
heavily bound by slow external network dependencies, consider Unicorn
instead as it simpler and easier to debug.

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

Changes:

Unicorn 0.97.0 has a bunch of internal cleanups and small fixes
and this is mainly to resync with those changes.

keepalive_timeout now defaults to 5 seconds (from 2 seconds
previous).  This should help out clients on slower connections.

Some small fixes and cleanups:

* Rainbows::Fiber::IO objects may leak if a rare app uses them
  explicitly with FiberSpawn/FiberPool-only (not RevFiberSpawn)

* quiet down ENOTCONN handling, there's nothing we can do about
  this error so we won't fill our logs with it.

    let Unicorn.builder parse switches in config.ru
    
    Less code for us is better

    keepalive_timeout defaults to 5 seconds
    
    The previous 2 second default was not enough for folks on slow
    connections where our OS socket buffers would've masked the time
    it took to write out larger responses.

    ev_core: avoid needless String#dup
    
    Just create an empty string instead and let Unicorn::HttpParser
    allocate it internally to whatever size is needed.

    don't bother supporting platforms without FD_CLOEXEC
    
    No point in having extra code around for platforms we
    don't care about.

    revactor: cleanups to avoid instance_eval
    
    instance_variable_{set,get} are faster, but equally ugly

    TCPSocket#peeraddr may raise ENOTCONN
    
    Since we deal with untrusted/non-local clients, those clients
    may disconnect at inopportune times and leave us with ENOTCONN
    when we try to call getpeername(2)

    avoid leaks if app uses Rainbows::Fiber::IO
    
    For the very rare apps out there using Rainbows::Fiber::IO, the
    FiberSpawn and FiberPool (but not RevFiberSpawn) models could
    leak memory if the app-created Rainbows::Fiber::IO objects
    were dereferenced without being removed from the RD/WR hashes.

    revactor/tee_input: sync w/ Unicorn::TeeInput struct-ification
    
    commit a5f4d11cdb9465b1ffa2892b3d84ee53b8962930 in unicorn.git
    switched all ivars to struct members for ease-of-hacking and
    object size.

    switch to Unicorn.builder, depend on Unicorn 0.97.0+
    
    The Unicorn.builder helper will help us avoid namespace
    conflicts inside config.ru, allowing us to pass tests.
    
    While we're at it, port some tests over from the latest
    unicorn.git for dealing with bad configs.

    test-lib: make FIFO start check an after_fork hook
    
    enabling ready_pipe in Unicorn 0.96.0 breaks this.

    test-lib: remove needless fd closing
    
    too dangerous with the ready_pipe feature in Unicorn 0.96+

    gemspec: bump dependency on Unicorn to avoid leak
    
    The HTTP parser in Unicorn <= 0.96.0 did not use the Ruby API
    correctly.  While this bug did not affect Unicorn itself,
    Rainbows! allocates a new Unicorn::HttpParser object for every
    client connection and Unicorn did not properly setup the parser
    object to be freed.

    use Hash#compare_by_identity for performance
    
    When available (Ruby 1.9), we can use Hash#compare_by_identity
    to improve performance.
