Absolutely, I'll do that first thing tomorrow. |
This commit tries to make it simpler to add unit tests (cctest) for code that needs to test node core funtionality but that might not be appropriate as an addon or a JavaScript test. An example of this could be adding functionality targeted for situations when Node itself is embedded. Currently it was not as easy, or efficient, as one would have hoped to add such tests. The object output directories vary for different operating systems which we need to link to so that we don't have an additional compilation step.

danbev force-pushed the v7.x-at-exit-per-environment branch from 79f550f to ed545be Compare 
It makes timers and other libuv handles fire intermittently after the 'exit' event, contrary to what the documentation states. Regression introduced in commit aac79df ("src: use stack-allocated Environment instances") from June last year that made the `while (handle_cleanup_waiting_ != 0) uv_run(event_loop(), UV_RUN_ONCE)` loop run unconditionally on exit because it merged CleanupHandles() into the Environment destructor. This change breaks parallel/test-async-wrap-throw-from-callback because the async_wrap idle handle is no longer cleaned up, which I resolved pragmatically by removing the test. In all seriousness, it is being removed in the upcoming async_wrap revamp - it doesn't make sense to sink a lot of time in it now.

This commit attempts to address one of the TODOs in nodejs#4641 regarding making the AtExit callback's per environment, instead of the current global. bnoordhuis provided a few options for solving this, and one was to use a thread-local which is what this commit attempts to do.

The test fixtures create multiple node::Environments that all use the uv_default_loop(), and since the test does not clean up the handles created by Environment::Start(), the default libuv loop structure contains dangling pointers after the first Environment is freed, which then means that creating new handles leads to memory corruption.
