| | | | | | | | | | | | | | | Return value of EXEC_TAG() is saved by "int state". Instead of "int", use "enum ruby_tag_type". First EXEC_TAG() value should be 0, so that define TAG_NONE (= 0) and use it. Some code used "status" instead of "state". To make them clear, rename them to state. We can change variable name from "state" to "tag_state", but this ticket doesn't contain it. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59155 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* improve handling of timer thread shutdownnormal2015-08-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Shutting down the timer thread now always closes pipes to free FDs. In fact, we close the write ends of the pipes is done in the main RubyVM to signal the timer thread shutdown. To effectively close pipes, we implement userspace locks via atomics to force the pipe closing thread to wait on any signal handlers which may be waking up. While we're at it, improve robustness during resource exhaustion and allow it to limp along non-fatally if restarting a timer thread fails.
