gh-73487: Convert ``_decimal`` to use Argument Clinic (part 1) by skirpichev · Pull Request #137606 · python/cpython · GitHub

Issue: decimal: Use Argument Clinic #73487

Is the help(decimal) output identical before and after the PR?

I appreciate suggestion on how to make it easier to review.

It looks worse than it actually is, only ~400 lines diff in _decimal.c and ~190 lines of docstring-only changes in _decimal/docstrings.h. You could maybe split up the Decimal methods into a few groups to reduce the size of the PR, but no obvious such groupings spring to mind.

It looks worse than it actually is

As I said, it's more or less a mechanical change. No changes in signatures, docstrings are copied from docstrings.h (though, AC enforces to have PEP summary line, most decimal docstrings don't follow this - that changed). There should be a minor speedup from using METH_FASTCALL (see issue thread for examples, I'll do benchmarks later, maybe add news). I'm planning to use also METH_METHOD where possible, but in a separate patch.

no obvious such groupings spring to mind.

Different types, then method functions? I don't see how to make such split uniform.

Do you think it's now too hard to review?

Yes. I'm happy to look at the changes, just in a future PR instead of this one.

This reverts commit 354d8db.

I would appreciate if #137624 can be merged first.

Now merged.

Serhiy also suggested (in #137685 (comment)) that AC conversions don't need NEWS entries, perhaps remove from this PR?

A

This reverts commit 98b0e38.

Now merged.

Thanks, I fixed errors. BTW, tool should display them all.

Removed. I fine with this, though PR affects performance and - thus - has user-visible changes.

If this affects performance, you can mention methods that have become significantly faster.

Why not rename dec to self?

Initially I did this, see reversion per reviewer request: 8b757da

I think that in long term it is better to change few more lines, but get rid of the self converter unless it is absolutely necessary (if we need a behavior different from default). But this is just nitpicks.

Restored.

If this affects performance, you can mention methods that have become significantly faster.

It's a long list, every function that previously used METH_VARARGS is affected. I can restore news again, does it make sense?

I can restore news again, does it make sense?

If it does not mention Argument Clinic and other implementation details.

Technically, LGTM.

But since there were objections to this conversion from the author and a former developer, we need approval from several core developers who have worked on the decimal module for many years.

This reverts commit 8b757da.

Ok, I asked @vstinner and @picnixz for review.

Raymond removed request for review, I hope this doesn't mean he is -1 on this.

LGTM. I like moving docstrings closer to function implementation, it helps to keep both consistent and up to date! The code is also easier to read. Hopefully, it may be even faster ;-)

Same opinion as Victor.

Merged. Thank you!

Thanks for reviews!
