chore(deps): bump attrs from 21.2.0 to 21.4.0

[dependabot]

Bumps attrs from 21.2.0 to 21.4.0.

Release notes

Sourced from attrs's releases.

21.4.0

This is a quick bug fix release for a regression that causes coverage report fail under certain circumstances.

Full Changelog

Changes

• Fixed the test suite on PyPy3.8 where cloudpickle does not work. #892
• Fixed coverage report for projects that use attrs and don't set a --source. #895, #896

21.3.0

This is a big release in the history of attrs and finishes an arc that took way too long and also delayed this very overdue release. But it's done: import attrs that has been talked about for years[^issue], but fell victim to “just this one more thing” has finally landed.

From now on, modern attrs code looks like this:

from attrs import define
@​define
class HelloWorld:
modern: bool = True

The define/field APIs have been around for over a year and were very popular, now the rest of the package followed suit. I'm very excited that attrs remains relevant and keeps evolving over now more than half a decade. If you're curious about some of the background, the docs now contain a short explanation and history lesson. As long as our users keep pushing us, we will keep pushing forward class generation in Python!

Big thanks to my GitHub Sponsors, Tidelift subscribers, and Ko-fi buyers that help me mustering the motivation for such long-running project!

---

Since the release took so long, there's more highlights than we can enumerate here, we'd just like to point out a breaking change in the new APIs: converters now run on setting attributes by default. If this is causing problems to you, you can disable that behavior by setting @define(on_setattr=[]).

[^issue]: I have an issue from 2018 that I wanted to "come back the moment this lands".

Full Changelog

Backward-incompatible Changes

• When using @define, converters are now run by default when setting an attribute on an instance -- additionally to validators. I.e. the new default is on_setattr=[attrs.setters.convert, attrs.setters.validate].

  This is unfortunately a breaking change, but it was an oversight, impossible to raise a DeprecationWarning about, and it's better to fix it now while the APIs are very fresh with few users. #835, #886

• import attrs has finally landed! As of this release, you can finally import attrs using its proper name.

  Not all names from the attr namespace have been transferred; most notably attr.s and attr.ib are missing. See attrs.define and attrs.field if you haven't seen our next-generation APIs yet. A more elaborate explanation can be found On The Core API Names

  This feature is at least for one release provisional. We don't plan on changing anything, but such a big change is unlikely to go perfectly on the first strike.

  The API docs have been mostly updated, but it will be an ongoing effort to change everything to the new APIs. Please note that we have not moved -- or even removed -- anything from attr!
