(Skipping news because this is an easter egg)

@ZeroIntensity Hmm... But isn't the CSV format legit, so in my (very bad) opinion it still need news?

[ZeroIntensity]

Oh, hm. I guess we could add an entry for only CSV. I'll leave the decision to @dpdani.

Yes, please add news for CSV format

[johnzhou721]

Yep, agreed with the NEWS part. But might it make the Easter Egg too obvious? Since people can just look at the PR through news. I think we might be able to split up the PRs into CSV and BSV and skip news on the latter, but it might be too much work.

We're not trying to hide or obsfucate; just not to advertise.

Sure, resolve.

I hate to be the not-funny one here but, while I think it's ok to have the CSV format, I would honestly prefer that we don't slip secret formats in this PR. The #119535 easter egg had a separate issue and PR and I would honestly prefer that for this one.

I think there's not much point duplicating the issue now, but splitting into two PRs can make sense.

@picnixz if you really think it's best, I can do the split.

[picnixz]

Yeah no need for two issues, but I would really like two separate PRs. For people reading commits, it's easier to spot the easter egg and it also makes reverting easier (if needed). It also allows us to make a funnier commit message. However, if @1st1 or any other codeowner is ok with adding the easter egg in this PR, I won't oppose their decision.

EDIT: I pinged the wrong code owner

[dpdani]

I'll split the PR now

[dpdani]

Split done.

The CSV format is here and the news entry is already ok.
Bananas in #137486

[AA-Turner]

As far as I can tell there are no existing tests for this, #133284 has some for build_task_table() and build_async_tree(), but not for display_awaited_by_tasks_table().

[dpdani]

Yeah, I saw it didn't have tests before and didn't think it would be necessary to add them here.
It was just a bunch of prints before, now there's a bit more logic, but still not a lot to test for, IMHO.

What do you think?

[dpdani]

Ah ok, you enabled auto-merge, I guess it's ok 👍

Thank you!
