=== 0.5.0 / 2009-11-05 10:27 UTC We depend on the just-released Unicorn 0.94.0 for the fixed trailer handling. As with `unicorn', the `rainbows' executable now sets and respects ENV["RACK_ENV"]. Also small fixes and cleanups including better FreeBSD 7.2 compatibility and less likely to over-aggressively kill slow/idle workers when a very low timeout is set. Eric Wong (20): rev: split out heartbeat class bump Unicorn dependency to (consistently) pass tests tests: avoid single backquote in echo event_machine: avoid slurping when proxying tests: make timeout tests reliable under 1.9 thread_pool: comment for potential SMP issue under 1.9 Allow 'use "model"' as a string as well as symbol Rev model is the only user of deferred_bodies ev_core: use Tempfile instead of Unicorn::Util::tmpio ev_core: ensure quit is triggered on all errors rainbows: set and use process-wide ENV["RACK_ENV"] http_server: add one second to any requested timeout thread_pool: update fchmod heartbeat every second t0004: tighten up timeout test ev_core: remove Tempfile usage once again cleanup: remove unused t????.ru test files tests: staggered trailer upload test ensure RACK_ENV is inherited from the parent env t0100: more precise `expr` usage === 0.4.0 / 2009-10-27 08:44 UTC Basic single-threaded EventMachine support is now included. It supports async_synatra[1] via the "async.callback" Rack environment[2]. For EventMachine, we rely on the updated attach/watch API in EventMachine 0.12.10. As Revactor 0.1.5 is now available, our Revactor support now depends on it as it adds the ability to listen on UNIX domain sockets. Of course, all dependencies (besides Unicorn and Rack) are soft and only loaded if your configured concurrency model requires it. For developers/QA folks, the integration tests are completely revamped for easier maintenance when new concurrency models are introduced and should also produce TAP-compliant output. The test suite remains highly parallelizable using GNU make. There are immediate plans to expand support for both Rev and EventMachine to support use with threaded application dispatch. Eric Wong (41): rev: remove Revactor-specific workaround README: change ordering of concurrency model listing tests: more correct HTTP/0.9 test test-lib: avoid stalling due to bad FIFO handling rev: fix static file responses under HTTP/0.9 add news bodies to site NEWS.atom.xml tests: avoid needlessly remaking "rainbows" initial EventMachine support tests: hopefully fix stalls in input trailer tests tests: avoid race condition in reopen logs test tests: prefer "RUBY" to lowercased "ruby" tests: common setup and wait_start functions tests: add a TAP producer shell library tests: port all existing tests to TAP library tests: remove symlinks and small files, use Make t9000: bail if run with an unsupported/pointless model tests: allow "make $model" to run tests for that model rev: spell ECONNABORTED correctly rev/evma: move common code for event models into ev_core ev_core: do not drop deferred bodies on graceful quits eventmachine: get basic tests working rev: do not File.expand_path on result of body.to_path eventmachine 0.12.8 passes all tests tests: make large file memory tests more reliable eventmachine: require EM 0.12.10 update gem dependencies in comments/local.mk.sample rev: enforce Rev::VERSION >= 0.3.0 eventmachine: add async_sinatra support tests: only load Revactor tests under 1.9.1 tests: gracefully exit if EventMachine is not available tests: error out if socat + curl aren't reachable thread*: fix MRI 1.8.6 compatibility local.mk.sample: cleanups and minor reorg eventmachine: remove unnecessary ivar assignment eventmachine: document our support of "async_synatra" doc: Update TODO and README tests: generate all dependencies atomically app_pool: update RDoc test-lib: DWIM handling of temp UNIX sockets revactor: require 0.1.5, remove 0.1.4 workarounds gemspec: bump up Unicorn dep version to 0.93.4 [1] http://github.com/raggi/async_sinatra [2] this is not 100% Rack::Lint compatible, but we'll let it slide since there are already folks depending on the async_sinatra gem === 0.3.0 / 2009-10-19 18:21 UTC The major feature of this release is the new DeferredResponse middleware for the Rev-based concurrency model. It should be transparently compatible with non-Rev models, as well. As a pleasant side effect, this change also allows large files to be streamed to the client with Rev as the socket becomes writable instead of slurping the entire file into an IO::Buffer first. Bugfixes to graceful shutdowns support for all concurrency models. The Rev-based model also gets a working heartbeat mechanism (oops!) and fixed HTTP/1.1 pipelining support. Eric Wong (38): app_pool: note it being currently broken with Revactor Revactor tests can sleep more easily tests: sleep.ru handles "Expect: 100-continue" Fix graceful shutdown handling of Thread* models harder DRY setting of rack.multithread test-lib: dbgcat adds headers with key name use timeout correctly to join threads on SIGQUIT Rev: simplification to error handling tests: sleep.ru slurps rack.input stream refactor graceful shutdowns again, harder tests: introduce require_for_model function tests: add unbuffered tee(1)-like helper tests: rack.input trailer tests for all models tests: fix issues with non-portable shell constructs tests: fix random_blob dependency tests: factor out a common parser error "library" tests: DRY setting of the "model" environment var tests: DRY Ruby requires based on model test-lib: quiet down pipefail error message tests: DRY require tests for Rev/Revactor rev: handle fully-buffered, pipelined requests rev: avoid stack overflow through pipelining tests: common basic HTTP tests for all models tests: rack.input hammer concurrency testing tests: for log reopening for all concurrency models http_response: filter out X-Rainbows-* headers rev: fix heartbeat timeouts revactor: switch to a 1 second heartbeat rev: async response bodies with DevFdResponse middleware tests: more reliable error checking tests: DWIM FIFO creation tests: predictable and simpler tempfile management rev: AsyncResponse => DeferredResponse API cleanup rev: update documentation for this model TUNING: update documentation notes TODO: update with new items local.mk.sample: sync with BDFL's version Rainbows! 0.3.0 === 0.2.0 / 2009-10-15 08:01 UTC 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). Eric Wong (54): add SIGNALS doc to RDoc SIGNALS: add Rainbows!-specific notes doc: better "Rainbows!"

Process-wide timeout handling for the ThreadSpawn concurrency model should now work properly. Small cleanups everywhere.
