Upstream: fixed running posted requests (ticket #788).
Previously, the upstream resolve handler always called
ngx_http_run_posted_requests() to run posted requests after processing the
resolver response. However, if the handler was called directly from the
ngx_resolve_name() function (for example, if the resolver response was cached),
running posted requests from the handler could lead to the following errors:
- If the request was scheduled for termination, it could actually be terminated
in the resolve handler. Upper stack frames could reference the freed request
object in this case.
- If a significant number of requests were posted, and for each of them the
resolve handler was called directly from the ngx_resolve_name() function,
posted requests could be run recursively and lead to stack overflow.
Now ngx_http_run_posted_requests() is only called from asynchronously invoked
resolve handlers.
