Although TsHashTable and the according API are supposed to easily make a HashTable thread-safe, they do not; for instance, there can be race conditions between finding and updating entries. We therefore avoid the usage of TsHashTable in favor of a HashTable with our own mutex management. The patch has been provided by krakjoe@php.net; I only did some minor fixes and tweaks.

If there are no objections, I'll merge this on 2019-07-08 (so it makes it into PHP 7.4.0alpha3) |
