=== 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!" RDoc examples and linkage tests: generate random_blob once for all tests tests: move trash files to their own trash/ directory t0000: basic test includes keepalive + pipelining tests: simplify temporary file management tests: add dbgcat() utility method fchmod heartbeat flips between 0/1 tests: add revactor pipelining/keepalive test thread_spawn: trap EAGAIN on accept_nonblock thread_spawn: more robust loop thread_spawn: non-blocking accept() shouldn't EINTR tests: enable pipefail shell option if possible README for test suite tests: TEST_OPTS => SH_TEST_OPTS tests: update TRACER examples in makefile tests: create a bad exit code by default thread_spawn: clean up nuking of timed-out threads factor out common listen loop error handling graceful exit on trap TypeError from IO.select expand and share init_worker_process revactor: break on EBADF in the accepting actors revactor: cleanups and remove redundancy No need to be halving timeout, already done for us revactor: graceful death of keepalive clients revactor: continue fchmod beat in graceful exit cleanup thread models, threads no longer time out revactor: fix graceful shutdown timeouts Fix graceful shutdowns for threaded models SIGINT/SIGTERM shuts down instantly in workers tests: check for common exceptions with "Error" DEPLOY: update with notes on DoS potential tests: add reopen logs test for revactor vs Unicorn: use diagrams for concurrency models vs Unicorn: fix wording to be consistent with diagrams vs Unicorn: fix copy+paste errors and grammar fail README: alter reply conventions for the mailing list preliminary Rev support local.mk.sample: use ksh93 as default $(SHELL) rack.multithread is only true for Thread* models Rev: general module documentation + caveats Rev: fix error handling for parser errors t3003: set executable bit documentation updates (mostly on network models) rack: expose "rainbows.model" in Rack environment tests: enforce rack.multithread and rainbows.model README: update URLs README: update with Rev model caveats Add Rainbows::AppPool Rack middleware t4003: chmod +x local.mk.sample: use rev 0.3.1 instead README: link to AppPool and extra note about Rev model Rainbows! 0.2.0 === 0.1.1 / 2009-10-06 03:51 UTC Fixed Ruby 1.8 support (and all 1.9 systems without Revactor). Process-wide timeout handling for the ThreadSpawn concurrency model should now work properly. Small cleanups everywhere.
