DEPR: remove previously-deprecated get_value, set_value #27377

Deprecated in 0.21.0

i would blow most/all of the _get_value and _set_value test away

im not sure we have other tests for _get_value/_set_value, which are still used internally

Any thought to migrating it to test_interals then? I can see the value of separating these out from other tests at the very least

jorisvandenbossche · 2019-07-13T14:18:20Z

Note I have nothing against this PR itself, but I don't think we should be removing things after the RC.

jbrockmendel · 2019-07-13T17:02:31Z

that makes sense, will move note to the 0.26.0 file

jbrockmendel · 2019-07-13T17:03:38Z

(or, since there is no 0.26.0 file yet, will wait until there is)

Looks like these two methods are used in tests scattered across a handful of files. Getting a better organization for indexing tests is worthwhile, but is a pretty big task

TomAugspurger · 2019-07-19T16:32:08Z

Are we just pretending like we're doing 0.26.0 for now, and moving to 1.0 if we decide we're ready? I think that makes the most sense.

That's the impression I got from [dont remember, but I'm 80% sure it wasn't a dream]

WillAyd · 2019-07-19T16:39:35Z

Just added the milestone - can change name as required

jreback

so are you sure we cannot simply remove entirely get_value and set_value? where exactly are these used outside of tests?

I see I think only

pandas/core//indexing.py:        self.obj._set_value(*key, takeable=self._takeable)

which could be use iat/at

@jbrockmendel

ok I guess this is not trivial to remove. However, this does need rationalization (e.g. the name is not inline with any other indexers, even internally that we have). So this should be addressed at some point; these routines likely are not great at handling for example non-basic dtypes as these never got love and have been externally replaced by iat/at.

So if we don't have an issue can you create one.thanks.

jreback · 2019-07-21T00:02:49Z

@jbrockmendel if you can't tell, I really really dislike doing these private version of public methods just so we can deprecate them, rather than actually fix things. This is just a propagation of technical debt and really hurting the project (just a bit of venting, you are certainly addressing lots of this prior techinical debt).

Definitely agreed on getting rid of the private versions before long. I've been looking at indexing methods and hoping to get some real simplification done before long.

Updated to also remove the deprecated methods from SparseSeries, SparseDataFrame.

It looks like iat and at dispatch to _get_value/_set_value. After this I'd like to do a follow-up to move the contents of _get_value/_set_value to iat/at and get rid of _get_value/_set_value altogether.
