Baseline is not updated automatically if there are new errors or warnings

[the-glu]

Description

The baseline file doesn't seems to be updated where there are no errors (witch is probably fine), but also when there are warnings.

I would expect it to be updated in the later case, it seems strange that removed errors are not recorded if there are warning that can be ignored (especially since the exit code is 0, since my failOnWarnings is set to False)

the intent is for the number of baselined errors to go down as you update old code without you having to manually update the baseline file. if new errors are introduced, it's likely unintentional which is why you have to explicitly run --writebaseline. see here for more info about the intended usage of the baseline file.

or perhaps i'm misunderstanding your issue? if so, could you provide the exact steps to reproduce the issue along with the expected behavior vs the actual behavior

[the-glu]

Yes, I do agree for the case of new errors that make sense, however my issue is mostly about new warnings with failOnWarnings set to false, where I would expect it to update the baseline (with removed errors only, not with new warnings).

[DetachHead]

i see. i guess it makes sense to do this when failOnWarnings is false

as a workaround you can set the rules to hint instead of warning, but that will prevent them from appearing when you run basedpyright in the CLI
