we may consider a different setting here (e.g. readonly
)

I generally prefer the attribute matching the parameter name.
We can have a property
@property
def readonly(self): return self.mode == "r"
Edit: which I see you have down below.

Thanks folks for the reviews here! |
Previously, opening a store in
w
mode, had a side effect (Store.clear
). That was leading to unexpected behavior when apath
argument was also supplied. This refactor takes the following approach:keepsStore.mode
but allows this to be onlyStoreAccessMode = Literal["r", "w"]
Store.mode
withStore.read_only
StorePath.open(..., mode: AccessModeLiteral)
where side effects can be applied at the path levelbuilds on #2430
closes #2359
