Errors with Hubot 2.19

[bryanrossUK]

Hi,

With hubot-2.19 with redis-brain-v0.0.4 and I get the following errors when I try to use hubot-eavesdrop-2.2.1. Any ideas on how to fix this?

I ran into the same thing. I'll make a PR that might be able to help.

👍

[acrewdson]

Strangely, I'm no longer seeing this -- I wonder if some other dep got updated that might have fixed the underlying issue? @liquidstate can you still reproduce the problem?

[bryanrossUK]

Apologies for taking so long to test this, but I'm still getting the same problem.

Each incoming message on the channel generates the following error:

Trying to use hubot when you hear cat respond with woof generates the following error:

@liquidstate to clarify, you reproduced the problem using my fork (commit be3673a)?

[bryanrossUK]

Sorry @acrewdson - didn't spot the fork. Many thanks for your help, much appreciated!

With the fork, i'm happy to report that it works! Not 100% bug free though I'm afraid!

With a fresh install and an empty brain with your fork I get the following error on all incoming messages:

hubot_1  | [Thu Jan 11 2018 22:59:29 GMT+0000 (UTC)] ERROR TypeError: Cannot read property 'sort' of null

However, once I create an action, such as when you hear dog respond with woof I get two notifications in the channel from the bot. Eg:

bryan:  testbot when you hear dog respond with woof
testbot: I am now listening for dog.
testbot: I am now listening for dog.

And, when I trigger that action, I get four responses from the bot. Eg:

bryan: nice dog
testbot: woof
testbot: woof
testbot: woof
testbot: woof

If I create further actions, then I get the same two confirmations and four responses when the action is triggered.

After creating an action, I no longer receive the same error as before on every message to the channel though. My guess is that this block of code doesn't deal well with an empty array?

    tasks = eavesDropper.all()
    tasks.sort (a,b) ->
      return if a.order >= b.order then 1 else -1

@liquidstate thanks for testing. I'll take another look. All signs point to some tricky race conditions that are not going to be easily fixed, since I didn't see any of what you describe last time I tested this -- but I also saw other weirdnesses that pointed to non-deterministic stuff going on. So I can't say I'm too surprised you found weird behavior, too. Will get back to you.
