1507860 - Use attrs throughout taskgraph.

Status: ASSIGNED

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.
