Async wrap providers tested: - crypto.randomBytes - crypto.pbkdf2 - fs event wrap - fsreqwrap access - fsreqwrap readFile - getaddrinforeq wrap - getnameinforeq wrap - pipe connect wrap - query wrap - pipewrap - processwrap - shutdown wrap - tcpwrap - udpwrap - send wrap - detailed signal wrap - statwatcher - timerwrap via setTimeout - timerwrap via setInterval - for Immediate - http parser request - http parser response - connection via ssl server - tls wrap - write wrap - ttywrap via readstream - ttywrap via wriream - zctx via zlib binding deflate Embedder API: - async-event tests - one test looks at the happy paths - another ensures that in cases of events emitted in an order that doesn't make sense, the order is enforced by async hooks throwing a meaningful error - embedder enforcement tests are split up since async hook stack corruption now the process - therefore we launch a child and check for error output of the offending code Additional tests: - tests that show that we can enable/disable hooks inside their lifetime events - tests that verify the graph of resources triggering the creation of other resources Test Helpers: - init-hooks: - returns one collector instance - when created an async hook is created and the lifetime events are registered to call the appropriate collector functions - the collector also exposes `enable` and `disable` functions which call through to the async hook - hook checks: - checks invocations of life time hooks against the actual invocations that were collected - in some cases like `destroy` a min/max range of invocations can be supplied since in these cases the exact number is non-deterministic - verify graph: - verifies the triggerIds of specific async resources are as expected, i.e. the creation of resources was triggered by the resource we expect - includes a printGraph function to generate easily readable test input for verify graph - both functions prune TickObjects to create less brittle and easier to understand tests PR-URL: https://github.com/nodejs/node/pull/12892 Ref: https://github.com/nodejs/node/pull/11883 Ref: https://github.com/nodejs/node/pull/8531 Reviewed-By: Andreas Madsen <amwebdk@gmail.com> Reviewed-By: Anna Henningsen <anna@addaleax.net> Reviewed-By: Sam Roberts <vieuxtech@gmail.com> Reviewed-By: Matteo Collina <matteo.collina@gmail.com> Reviewed-By: Refael Ackermann <refack@gmail.com> Reviewed-By: James M Snell <jasnell@gmail.com> Reviewed-By: Jeremiah Senkpiel <fishrock123@rocketmail.com>
