HTTPParser reuse causes confusing contexts.

[RobinQu]

Failing test case: https://github.com/RobinQu/async-zone/blob/master/test/http_test.js#L70

My guess:

• request callback is bound to HTTPParser
• HTTPParser's init hook is only called the first time it's created and not called after reuse.
• the context bound to that HTTPParser is not changed since the creation, thus all async callbacks associated to HTTPParser are run in an incorrect zone.

Run with DEBUG

HTTPParser's init hook is only called the first time it's created and not called after reuse.

I can confirm this. See also nodejs/node#5573, my guess is that the PR won't land, but the issue will be fixed when AsyncWrap gets finalized.

I also gave your code a 30 sec look. I think it's correct, but I would suggest that you use uid and Map (cleanup in destroy) instead of handle and WeakMap. It's much more performant and in the future the handle will only be available from init.

@AndreasMadsen Thanks for your review.

I found asyncwrap API in both 4.5LTS and 6.5 current, so I thought it was already finalized.

And then, I came across the nodejs/node-eps#18 you referenced and was surprised that there are so many upcoming changes.

[AndreasMadsen]

Yes, there is alot going on. Developing an API like AsyncWrap is a time consuming process and we can't simply create an API and hope for the best. The proposed API (eps) is the results from what we have learned from the current implementation, which have purposely been kept unofficial such that we could change it.

[RobinQu]

@AndreasMadsen Understood. Looking forward to the next release so that we can make Zone a really working infrastructure that powers transactional scenarios like web server, data persistence etc.
