OCSP cache doesn’t have a means of clearing all cache invalidation check intervals

[aral]

Use case

While running unit tests that use the OCSP cache, the Node process does not exits due to active handles (the cache expiry intervals)

Suggested fix

Add a method that clears the cache and cache expiry interval checks. e.g.,

Cache.prototype.clear = function clear() {
  var cacheIds = Object.keys(this.cache);
  cacheIds.forEach(function (cacheId) {
    clearInterval(this.cache[cacheId].timer);
  })
  this.cache.length = 0;
};

Workaround

In your app, clear the intervals manually. e.g., in my app:

const ocspCache = new ocsp.Cache()
// …
const cacheIds = Object.keys(ocspCache.cache)
cacheIds.forEach(cacheId => {
  clearInterval(ocspCache.cache[cacheId].timer)
})
