[issue3312] bugs in _sqlite module
|
|
New submission from STINNER Victor <haypo[at]users.sourceforge.net>:
(A) module_register_adapter() doesn't check microprotocols_add()
result, whereas it can fails (eg. dict setitem error).
Example: "import _sqlite3; _sqlite3.register_adapter({}, None)" =>
should raise a TypeError (unhashable type: 'dict').
(B) Connection.set_isolation_level() tries to create the
string "BEGIN "+isolation_level and the store it as PyString in
begin_statement. But if the result can not be converted to string,
Python crashs. Example:
>>> import _sqlite3
>>> c=_sqlite3.Connection("a")
>>> c.isolation_level = u"\xe9"
Erreur de segmentation (core dumped)
Attached patch fix the two bugs.
