I just had a weird bug, and even though it's fixed, I don't understand what's going on: The bug was that I had written an event handler with reg-event-fx, and only returned a :dispatch key, no :db. The thing is: it worked fine, so I guess I tried it and found that it's not necessary to type the extra :db a few times. But now I registered a global event handler, and suddenly things were going wrong, since the effects db was nil. I suppose there's a mechanism that copies the db if the effects db isnt there at the end of the chain? Is that something well known?

I’m running into an Eval timed out! error message when trying to sub some but not all of my subscriptions. Seems to be the ones with a lot of data, also seems to be associated with the error (which appears in nrepl buffer) WARN - Max payload length 4m, get: 4322857 , which i think is a websocket-related warning? Kind of stumped by this one. I’ve tried the easy stuff like lein clean and restart repl, but no luck. This started happening recently too…
