The docs describe LibModel.items() to

Iterate over (key, value) pairs that this object contains. Computed fields are not included.

This is the case for Item.items(), but Album.items() gives all the Items associated with the Album.

LibModel.items() is actually defined in Model.items(), and overwritten in the Album class.

So I'm wondering what the intended behavior is :)

I know I have used Album.items() as it currently is in the past (and it seems to me a sensibly named function). Just now I tried to use it in the sense defined in the docs and ran into this problem (although I want computed fields so not using it any more). In the docs sense I guess the items() mimics dict.items(), but does create some confusion with Items :D

You've hit the nail on the head. It's an unfortunate naming collision—one that exists mainly for historical reasons. Namely, the Item and Album objects predate dbcore; we refactored the latter out of the core beets library to bring a little more abstraction and modularity. So the Album.items() method is very old and special-purpose, while the new(er) Model.items() is generic.

So yes, it's not a great situation, but it's not clear what we should do instead. Perhaps rename Album.items() to something else someday?

While unfortunate; this seems like a change that would break many third-party plugins. In my opinion, we should avoid renaming .items() (unless there's a stronger reason than being somewhat confusing). Maybe extending the Album.items() docstring to point this out would help to alleviate the issue?

Yep I think just documenting the conflict would be good. Doesn't seem like it's been too much of an issue in the past.

Would you be able to make a quick PR for this?

    Refactor query utilities

    We now use somewhat more general query constructors in `dbcore`,
    avoiding the need for somewhat special-purpose `duplicates` methods on
    the model objects.

    Remove `match_querystring` in `responses`

    Quoth the responses documentation:

    Not sure how recent this is, unfortunately---but probably 0.17.0, since
    that's the version where `match_querystring` was deprecated.

commit f71e503
Author: Adrian Sampson <[email protected]>
Date:   Wed Aug 17 16:05:33 2022 -0700

    Change the prefix for exact match queries

    PR beetbox#4251 added exact match queries, which are great, but it was
    subsequently pointed out that the `~` query prefix was already in use:
    beetbox#4251 (comment)

    So this changes the prefix from `~` to `=~`. A little longer, but
    hopefully it makes the relationship to the similarly-new `=` prefix obvious.
