This is the result of a general audit of how we fork threads, with a detour into how we're using mutable state especially in websocket codepaths, making more robust to async exceptions and exceptions resulting from bugs. Some highlights: - use a wrapper around 'immortal' so threads that die due to bugs are restarted, and log the error - use 'withAsync' some places - use bracket a few places where we might break invariants - log some codepaths that represent bugs - export UnstructuredLog for ad hoc logging (the alternative is we continue not logging useful stuff) I had to timebox this. There are a few TODOs I didn't want to address. And we'll wait until this is merged to attempt #3705 for Control.Concurrent.Extended |
