[New-bugs-announce] [issue43752] Fetching an empty value from date column crashes on SQLite.

[Mariusz Felisiak]

New submission from Mariusz Felisiak <felisiak.mariusz at gmail.com>:

We noticed a regression in Python3.10.0a7 (it works properly in Python3.10.0a6) when running Django's test suite. `convert_date()`[1] is called and crashes when fetching an empty value from `date` column on SQLite:

File "python3.10/lib/sqlite3/dbapi2.py", line 64, in convert_date
    return datetime.date(*map(int, val.split(b"-")))
ValueError: invalid literal for int() with base 10: b''

I will bisect a regression and submit PR.
