1507860 - Use attrs throughout taskgraph.

Status: RESOLVED FIXED

(Firefox Build System :: Task Configuration, task)

Description

[Tom Prince [:tomprince]]

attrs is now vendored in tree, but much of the code pre-dates it. We should migrate as much as is sensible to use attrs.

[Gregory Szorc [:gps]]

I strongly approve: attrs is terrific.

This moves most of the low-hanging fruit to use attrs.

I'm guessing this change is behind my mysterious try push failures at [1] and [2] (error message: "AttributeError: 'frozenset' object has no attribute 'add'"). Is this expected?

It is due to this change, and isn't expected. I've backed out, and relanded with a fix.

Thanks! I've verified that the new version doesn't have the same problem.

The leave-open keyword is there and there is no activity for 6 months.
:tomprince, maybe it's time to close this bug?

There's likely still work to be done here, but we're also talking about deprecating 3.6 and/or vendoring the dataclasses backport. So I'm going to resolve for now and we can file a new bug when / if the need arises.. though this will likely never be prioritized.
