Automatically add a testcase via a comment

[hellow554]

Just like @rustbot can be pinged, why not using the same with @rust-lang-glacier-bot?

I would suggest something like this:

---

Hey, I found a mcve for this ICE. With this mcve it works.

fn main() { panic!() }

@rust-lang-glacier-bot add ICE https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=34dc5c9d1e14ff10ff8be22be265e7ef

---

Then the bot can try the playgroundand see if it ICEs and automatically adds it.

If we don't want an automatism, something like @rust-lang-glacier-bot +r can be used, similar to @bors.

What do you think?

[hellow554]

Also it should be possible to update an ice, but using update ICE <playgroundlink?

So, we have to serve and manage glacier-bot like rustbot(triagebot)? If so, I'm not sure but it may be a burden to the members (particularly infra team).

[hellow554]

Can you explain the "serve and manage" part a little bit more? I never developed a github bot, nor looked I at the source of rustbot/triagebot/bors. I do not know how much effort it is to develop such bot.

But we can aggree, that it will be a burden to somebody. But it will be increase the awareness and the usefulness of this repository. Nobody needs to open a PR anymore, nobody needs to approve it (well, if we go for the +r method, then somebody must approve it, but centril of jonas are around everywhere ^^)

It's up to you to decide wether it's worth the effort to develop (and maintain (?)) such a bot.

I would be happy to accept a patch that includes this functionality into triagebot, but I don't think we need a separate bot for this.

[hellow554]

Should this issue be transfered to the https://github.com/rust-lang/triagebot/ repo then?

[Mark-Simulacrum]

I would imagine that tracking it here makes more sense, but feel free to reopen there if needed.

Sounds good, I agree with that!

rust-lang/triagebot#526 landed, so this should probably be closed?

[Mark-Simulacrum]

We should test it out first :)

[LeSeulArtichaut]

Should we have a dummy ICE PR? Or do we want to wait until we have an ICE with MCVE ready?

[JohnTitor]

I tried in rust-lang/rust#72554 and we should have enabled glacier command in the rust-lang/rust at first... And the current command is tricky for me, we should also document this in the wiki.

[JohnTitor]

Hm, I tried with rust-lang/rust#72554 (comment) but there is no response for about an hour.
