Unicorn 0.92.0

Unicorn is a Rack HTTP server for Unix and fast clients

Small fixes and documentation are the focus of this release.

James Golick reported and helped me track down a bug that caused
SIGHUP to drop the default listener (0.0.0.0:8080) if and only
if listeners were completely unspecified in both the
command-line and Unicorn config file. The Unicorn config file
remains the recommended option for specifying listeners as it
allows fine-tuning of the :backlog, :rcvbuf, :sndbuf,
:tcp_nopush, and :tcp_nodelay options.

There are some documentation (and resulting website)
improvements. setup.rb users will notice the new section 1
manpages for unicorn and unicorn_rails, Rubygems users
will have to install manpages manually or use the website.

Edit: That’s not entirely true, I screwed up the package but
you can get them from http://unicorn.bogomips.org/unicorn.1
and http://unicorn.bogomips.org/unicorn_rails.1

The HTTP parser got a 3rd-party code review which resulted in
some cleanups and one insignificant bugfix as a result.

Additionally, the HTTP parser compiles, runs and passes unit
tests under Rubinius. The pure-Ruby parts still do not work yet
and we currently lack the resources/interest to pursue this
further but help will be gladly accepted.

The website now has an Atom feed for new release announcements.
Those unfamiliar with Atom or HTTP may finger [email protected]
for the latest announcements.
