This is a massive breaking change for users, we need to have a deprecation period where the old syntax still works but a deprecation message is displayed. Check out https://docs.astropy.org/en/stable/api/astropy.utils.decorators.deprecated.html#astropy.utils.decorators.deprecated

There should be two changelog entries, one under MAST and one under Gemeni.

This is a massive breaking change for users, we need to have a deprecation period where the old syntax still works but a deprecation message is displayed. Check out https://docs.astropy.org/en/stable/api/astropy.utils.decorators.deprecated.html#astropy.utils.decorators.deprecated

Would it be a good idea to assign the old name of the class to the new name
e.g ObservationsClass = GeminiObservationsClass()
and display a deprecated message saying ObservationsClass is deprecated. Use GeminiObservationsClass instead

You can use this PR as an example for renaming and deprecating a class: astropy/astropy#9445

Nice! Thanks @bsipocz

ceb8 · 2020-11-11T18:18:10Z

@olyoberdorf You probably want to take a look at this too.

olyoberdorf · 2020-11-11T18:40:43Z

Gemini is very new, but the deprecation work would be essentially identical to what's needed for MAST. So you may as well do both. Also, thanks for working on my module :)

bsipocz

Overall this looks good to me, and I only have some minor comments, one of them needs input from @ceb8.

However, the documentation should also be updated before we merge this.

this is nitpicking, so I only point out to show better practice: changelog should point out what has changed, and what the new solution is. No need to mention the module name in the changelog as the section above already contains that information. The backticks are to highlight the class names when rendered for the documentation.

Suggested change

- Renamed and deprecated Observations and ObservationsClass in GEMINI module. [#1885]

- Renamed and deprecated ``Observations`` and ``ObservationsClass`` to ``GeminiObservations`` and ``GeminiObservationsClass`` . [#1885]

I think we don't recommend wildchar imports, so removing the old class names from the namespace is probably safe.

bsipocz · 2020-11-14T22:57:21Z

Oh, and as I see there are some conflicts due to a PR that has been merged in the meantime, so this will need a rebase at some point (better to do it once you've done the docs updates, too).

Also, note to maintainers that travis is gone, and I have to fix the CI before we can reasonably merge anything.

ceb8 · 2020-11-16T17:22:18Z

@bsipocz Which of your comments did you need my input on?

Also thanks for remembering the documentation! Super important!

bsipocz · 2021-04-20T01:12:51Z

This needs a rebase due to conflicts. I may try to get to it before release to make sure the deprecations end up in the release.

Hello @tinumide! Thanks for updating this PR. We checked the lines you've touched for PEP 8 issues, and found:

~~Good news, I see the docs build error on this branch locally, too. Bad news, I don't see the reason, the same build passes.~~ See inline comment for the fix.

The deprecation of the instances in a way that the warning is not raised at module import time is I suppose the last outstanding issue, but there I don't yet have a solution.

bsipocz · 2021-07-02T03:39:01Z

And I spotted one more issue, if you do an import the deprecation warnings should not show. I only have an ugly workaround for the class instance and I'm not sure how I could force it to emit a deprecation when used, but not when the module is imported.

This line is causing the warning. I guess the brute force way is to silence the warning just for this line...?

Yes, the issue is that if I put a filter in __init__.py, then we rightly don't get the warning at module import time. However, then we don't get it at all for any usage of Observations, and that's what probably users used the most as the docs is full of Observations.xzy().

bsipocz · 2021-07-03T00:43:03Z

I'm sorry, but this has to wait for the next release, I just can't find a way to have all our cases covered, to make sure all users who use the old names to see the warning, but those using the new one don't.

bsipocz · 2022-03-18T04:23:23Z

Heads up @ceb8 @jaymedina @tomdonaldson @olyoberdorf: I would like to go ahead with this sooner rather than later. Would you be still on board? Basically we already followed the same logic with the new class in mast, calling it e.g. MastMissions.

It is understood that we'll need long deprecation period, for both modules so for a while all the users will experience is a deprecation warning at the time of import.

As I see the last comments in here, this got stalled with some issues around getting the right warning in all situations. Besides fixing that, do you see any blockers with the proposed idea?

olyoberdorf · 2022-03-18T04:44:54Z

Hi Brigitta, Yeah still on board. I don’t recall any other problems. I’m on vacation but I am back this weekend.
