Rainbows! 0.91.0 - Unicorn resync

Rainbows! is an HTTP server for sleepy Rack applications. It is based
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.


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.

Zbatery is an HTTP server for Rack applications on systems that either
do not support fork(), or have no memory (nor need) to run the
master/worker model. It is based on Rainbows! (which is based on
Unicorn (which is based on Mongrel)) and inherits parts of each.
Zbatery supports your choice of all the thread/fiber/event/actor-based
concurrency models and Rack middleware that Rainbows! supports (or will
ever support) in a single process.

This release resyncs against the latest features/cleanups
in Unicorn 0.97.0 and Rainbows! 0.91.0
