[New-bugs-announce] [issue7670] _sqlite3: Block *all* operations on a closed Connection object

[STINNER Victor]

New submission from STINNER Victor <victor.stinner at haypocalc.com>:

Add call to pysqlite_check_connection() on the follow methods:

 * create_function()
 * create_aggregate()
 * set_authorizer()
 * set_progress_handler()
 * __call__()

Eg. fix the following segfault:

   c = Connection("test")
   c.close()
   c.set_authorizer(func)

The patch includes unit tests to test all methods on a closed connection.

sqlite3 already raises an error for some operations on a closed socket (eg. connection.commit()), but not on all operations.
