This is an extraction from (and a continuation of) #1006, which should be merged first.
Many of these may be trivial to implement in pure ruby mode, and some may be impossible, but for right now I'd prefer to simply have them all displayed as a "TODO list" in the test results.
This would have broken many tests that were previously omitted based on whether or not
EM
responds to these methods. However an earlier commit marked those tests as pending in pure_ruby mode.A minor tradeoff of this PR is that EM.respond_to?(method) cannot be used as a feature detection mechanism. However, it's my belief that it already can't be used reliably for that. Additionally, most of these methods are marked as
# @private
, so users of EventMachine really should not make any assumptions about them. And fortunately, in my searches of public code, these are not the methods that people are checking.
