3 years agoFix incorrect handling of module runtime and environment pointers.
Philipp Stephani [Fri, 27 Nov 2020 18:08:55 +0000 (19:08 +0100)]
Fix incorrect handling of module runtime and environment pointers.

We used to store module runtime and environment pointers in the static
lists Vmodule_runtimes and Vmodule_environments.  However, this is
incorrect because these objects have to be kept per-thread.  With this
naive approach, interleaving module function calls in separate threads
leads to environments being removed in the wrong order, which in turn
can cause local module values to be incorrectly garbage-collected.

Instead, turn Vmodule_runtimes and Vmodule_environments into
hashtables keyed by the thread objects.  The fix is relatively
localized and should therefore be safe enough for the release branch.

Module assertions now have to walk the pointer list for the current
thread, which is more correct since they now only find environments
for the current thread.

Also add a unit test that exemplifies the problem.  It interleaves two
module calls in two threads so that the first call ends while the
second one is still active.  Without this change, this test triggers
an assertion failure.
