[3.10] bpo-43853: Expand test suite for SQLite UDF's (GH-27642) by erlend-aasland · Pull Request #31030 · python/cpython

GH-27613 (bpo 44839) was not backported, so exceptions differ between main and older versions. See 28de39f.

@gvanrossum I'm planning to merge this (a backport of #27642 which you previously merged after my review). The only non-test changes fix a missed error check for PyFloat_AsDouble, so this should be fine in the bugfix branches.

+1. If adding tests never caused us to fix any bugs we’d be doing it wrong. :-)

Sorry, @erlend-aasland and @JelleZijlstra, I could not cleanly backport this to 3.9 due to a conflict.
Please backport using cherry_picker on command line.
cherry_picker ba457fe6f8e50ad3ef3ceffb75dee96629a42ad7 3.9

Thanks; I'll fix the 3.9 backport.
