Jakob Ackermann	2d1c84ea2e	[misc] fix collection of open sockets ... ``` > require('http').globalAgent.sockets { 'HOST:PORT:': [{ ... }, { ... }] } ``` - `new URL('http://HOST:PORT:')` throws -> test suite `open_sockets` - gauges were not cleaned up after no agents were present for a given key. This lead to continuous emission of the previous connection count for a given hostname, following the completion of all requests. -> test suite `when all requests complete`	2020-11-06 15:16:14 +00:00

Eric Mc Sween	2f35db4087	Fix startup crash ... Version 3.2.0 crashes on startup because it calls buildPromKey() without arguments. To avoid this kind of obvious bug to happen again, I added some basic acceptance tests.	2020-09-17 10:30:25 -04:00
