Needs whatsnew note.

This has the benefit of looking a lot like the SparseDataframe._combine_frame implementation. With luck we can de-duplicate those at some point.

Likely to be a perf hit for non-td64 dtypes. One option would be to use dispatch_to_series more selectively, but that gets complicated in a hurry.

I think long-term the perf solution is going to be to dispatch to EA ops instead of Series ops, as discussed briefly in #22614, but that is a ways away.

  • closes #22537
  • tests added / passed
  • passes git diff upstream/master -u -- "*.py" | flake8 --diff

Hello @jbrockmendel! Thanks for updating the PR.

Looks like Series/DataFrame have some different behavior for bool ops... will look into this.

There are a handful of dispatch functions scattered about this module. In a follow-up I'd like to collect them in one place.

In preperation for PeriodArray / DatetimeArray / TimedeltaArray.

Index.shift has a different meaning from ExtensionArray.shift.

- Index.shift pointwise shifts each element by some amount
- ExtensionArray.shift shits the *position* of each value in the array
  padding the end with NA

This is going to get confusing. This PR tries to avoid some of that by
internally using a new `_tshift` method (time-shift) when we want to do pointwise
shifting of each value. Places that know they want that behavior (like in the
datetimelike ops) should use that.

* Use ._tshift internally for datetimelike ops

In preperation for PeriodArray / DatetimeArray / TimedeltaArray.

Index.shift has a different meaning from ExtensionArray.shift.

- Index.shift pointwise shifts each element by some amount
- ExtensionArray.shift shits the *position* of each value in the array
  padding the end with NA

This is going to get confusing. This PR tries to avoid some of that by
internally using a new `_tshift` method (time-shift) when we want to do pointwise
shifting of each value. Places that know they want that behavior (like in the
datetimelike ops) should use that.

* Use ._tshift internally for datetimelike ops

In preperation for PeriodArray / DatetimeArray / TimedeltaArray.

Index.shift has a different meaning from ExtensionArray.shift.

- Index.shift pointwise shifts each element by some amount
- ExtensionArray.shift shits the *position* of each value in the array
  padding the end with NA

This is going to get confusing. This PR tries to avoid some of that by
internally using a new `_tshift` method (time-shift) when we want to do pointwise
shifting of each value. Places that know they want that behavior (like in the
datetimelike ops) should use that.

* Use ._tshift internally for datetimelike ops

In preperation for PeriodArray / DatetimeArray / TimedeltaArray.

Index.shift has a different meaning from ExtensionArray.shift.

- Index.shift pointwise shifts each element by some amount
- ExtensionArray.shift shits the *position* of each value in the array
  padding the end with NA

This is going to get confusing. This PR tries to avoid some of that by
internally using a new `_tshift` method (time-shift) when we want to do pointwise
shifting of each value. Places that know they want that behavior (like in the
datetimelike ops) should use that.
