Rainbows! 0.2.0
This release adds preliminary Rev support for network
concurrency under Ruby 1.8 and Ruby 1.9. There are caveats to
this model and reading the RDoc for Rainbows::Rev is
recommended.
Rainbows::AppPool Rack middleware is now available to limit
application concurrency on a per-process basis independently of
network concurrency. See the RDoc for this class for further
details.
Per-client timeouts have been removed, see
http://mid.gmane.org/
20091013062602.GA13128@dcvr.yhbt.net
for the reasoning.
Rack environment changes:
* "rack.multithread" is now only true for models with "Thread"
in their name. Enabling thread-safe (but not reentrant) code
may actually be harmful for Revactor.
* "rainbows.model" is now exposed so the application can easily
figure out which network concurrency model is in use.
Bugfixes include better shutdown and error handling for all
existing models, OpenBSD compatibility for the per-process
heartbeat (same as found in unicorn v0.93.3).
