[New-bugs-announce] [issue31740] refleaks when calling sqlite3.Connection.__init__() more than once

[Oren Milman]

New submission from Oren Milman <orenmn at gmail.com>:

The following code causes refleaks:
import sqlite3
connection = sqlite3.Connection.__new__(sqlite3.Connection)
connection.__init__('foo')
connection.__init__('foo')

This is because pysqlite_connection_init() (in Modules/_sqlite/connection.c)
doesn't decref (if needed) before assigning to various fields of `self`.

I would open a PR to fix this soon.
