| | = Unicorn: UNIX + LAN/localhost-only fork of Mongrel
Only run this behind a full-HTTP-request-buffering reverse proxy if
you're serving slow clients. That said, nginx is the only reverse
proxy we know of that meets this requirement.
== Features
* process management: Unicorn will reap and restart workers that
die because of broken apps and there is no need to manage
multiple processes yourself.
* does not care if your application is thread-safe or not, workers
all run within their own isolated address space and only serve one
client at a time...
* able to listen on multiple interfaces, including UNIX sockets,
each worker process can also bind to a private port via the
after_fork hook for easy debugging.
* supports all Rack applications
* nginx-style binary re-execution without losing connections.
You can upgrade unicorn, your entire application, libraries
and even your Ruby interpreter as long as unicorn is
installed in the same path.
* before_fork and after_fork hooks in case your application
has special needs when dealing with forked processes.
* builtin log rotation via USR1 signal
* Ruby 1.9-compatible (at least the test cases all pass :>)
== License
Unicorn is copyright 2009 Eric Wong and contributors.
It is based on Mongrel:
Mongrel is copyright 2007 Zed A. Shaw and contributors. It is licensed
under the Ruby license and the GPL2. See the include LICENSE file for
details.
== Install
The library consists of a C extension so you'll need a C compiler or at
least a friend who can build it for you.
Finally, the source includes a setup.rb for those who hate RubyGems.
You can get the source via git via the following locations:
git://git.bogomips.org/unicorn.git
http://git.bogomips.org/unicorn.git
== Usage
Unicorn will look for the config.ru file used by rackup in APP_ROOT.
Optionally, it can use a config file specified by the --config-file/-c
command-line switch.
Unicorn should be capable of running all Rack applications. Since this
is a preforking webserver, you do not have to worry about thread-safety
of your application or libraries. However, your Rack application may use
threads internally (and should even be able to continue running threads
after the request is complete).
== Contact
Newsgroup and mailing list coming, or it'll be a part of the Mongrel project...
Email Eric Wong at normalperson@yhbt.net for now.
