Rainbows! is a 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/](http://rainbows.rubyforge.org/) - removed\_email\_address@domain.invalid - git://git.bogomips.org/rainbows.git Changes: Client shutdowns/errors when streaming “rack.input” into the Rack application are quieter now. Rev and EventMachine workers now shutdown correctly when the master dies. Worker processes now fail gracefully if log reopening fails. ThreadSpawn and ThreadPool models now load Unicorn classes in a thread-safe way. There’s also an experimental RevThreadSpawn concurrency model which may be heavily reworked in the future… Eric W. (31): Threaded models have trouble with late loading under 1.9 cleanup worker heartbeat and master deathwatch tests: allow use of alternative sha1 implementations rev/event\_machine: simplify keepalive checking a bit tests: [sha1.ru](http://sha1.ru) now handles empty bodies rev: split out further into separate files for reuse rev: DeferredResponse is independent of parser state remove unnecessary class variable ev\_core: cleanup handling of APP constant rev: DeferredResponse: always attach to main loop initial cut of the RevThreadSpawn model rev\_thread\_spawn/revactor: fix TeeInput for short reads rev\_thread\_spawn: make 1.9 TeeInput performance tolerable tests: add executable permissions to t0102 tests: extra check to avoid race in reopen logs test rev\_thread\_spawn: 16K chunked reads work better tests: ensure proper accounting of worker\_connections tests: heartbeat-timeout: simplify and avoid possible race tests: ensure we process “START” from FIFO when starting http\_response: don’t “rescue nil” for body.close cleanup error handling pieces tests: more stringent tests for error handling revactor/tee\_input: unnecessary error handling gracefully exit workers if reopening logs fails revactor/tee\_input: raise ClientDisconnect on EOFError bump versions since we depend on Unicorn::ClientShutdown FAQ: updates for Rails and SSL-using sites revactor/tee\_input: share error handling with superclass RevThreadSpawn is still experimental Revert “Threaded models have trouble with late loading under 1.9” Rakefile: add raa\_update task
