Urbit: Chat-cli crashes on faulty text

[rabsef-bicrym]

After a heavy day of chatting, I left for a while and came back to the error below. It appears dojo is still functional, I can reach other ships through hi, but I am not seeing any incoming chats nor do I see new chats I post to channels appear in the record after entering them in prompt

error in %chat-cli

%chat-cli-kicked

[Fang-]

(In the future, use triple-` for multi-line codeblocks. (; )

This looks like it's crashing here, which has been reported in the past, and is some weird text conversion edge case. I got it too. I suspect the offending message was in urbit-help, meaning everyone subscribed to it got affected too.

For some reason chat-cli doesn't have %kick handling, so it doesn't automagically recover from this. I'll go and put that in, and try and see if I can get a hotfix OTA in to fix this.

In the past, I've been able to run :chat-cli %connect to fix the "no new messages in chat-cli" state. For some reason, this doesn't seem to work now. Will investigate.

[Fang-]

The "no %kick handling" part of this is resolved as per #2128.

[mocknotes]

cli spit out a bunch of error messages after the following message:

landscape:

As reported above cli no longer shows incoming messages, however I can still send and receive messages in landscape.

[Fang-]

Oops. #2147 should fix the subscribe failed part of this. If that had worked correctly, chat-cli would still crash, but then proceed to function normally.

For now, you can run :chat-cli %connect from dojo to reconnect it, so that it starts printing new messages again.

Just hit a 'weird-text' crash when joining ~/~dopzod/urbit-help. I was still able to join successfully, though. Not sure which text is implicated by the crash.

@belisarius222 this suggests you are running an older version of chat-cli. b35129e5 replaced the %weird-text crashes with a less noisy fallback message:

https://github.com/urbit/urbit/blob/18e396cf5383531f9ccdefc3090587f200268649/pkg/arvo/app/chat-cli.hoon#L1346-L1352

I saw you breached, and know we updated the pill very recently, so wonder how you got to be running outdated chat-cli...
