Hello,
Bug report
Consider the following code snippet:
$ cat /tmp/test.py
import sqlite3
class SqliteConnection(sqlite3.Connection):
def __init__(self, *args, **kwargs):
print(args)
print(kwargs)
super(SqliteConnection, self).__init__(*args, **kwargs)
db_path = '/tmp/foo.db'
sqlite3.connect(db_path, factory=SqliteConnection)And the execution:
$ python3.10 /tmp/test.py
('/tmp/foo.db',)
{'factory': <class '__main__.SqliteConnection'>}
$ python3.11 /tmp/test.py
('/tmp/foo.db', 5.0, 0, '', 1, <class '__main__.SqliteConnection'>, 128, 0)
{}The default values of sqlite3.connect's arguments are passed to the factory in
Python3.11, which was not the case in Python3.10. This means that code like
this will fail:
$ cat /tmp/failure.py
import sqlite3
class SqliteConnection(sqlite3.Connection):
def __init__(self, *args, **kwargs):
kwargs['timeout'] = 42
super(SqliteConnection, self).__init__(*args, **kwargs)
db_path = '/tmp/foo.db'
sqlite3.connect(db_path, factory=SqliteConnection)$ python3.10 /tmp/failure.py
$
$ python3.11 /tmp/failure.py
Traceback (most recent call last):
File "/tmp/failure.py", line 11, in <module>
sqlite3.connect(db_path, factory=SqliteConnection)
File "/tmp/failure.py", line 7, in __init__
super(SqliteConnection, self).__init__(*args, **kwargs)
TypeError: Connection() takes at most 8 arguments (9 given)Your environment
This behaviour appeared in 185ecdc and affects
Python 3.11 and later.
It was mentioned in #93044 (see the
second bullet point in the reporter's message) but has not been fixed.
