Good night everybody!.
Working on the Python3.0 support for bsddb I see that "Py_FindMethod"
was just removed in Python last beta.
Most uses of "Py_FindMethod" can be resolved as (as far as I know):
1. Delete the getattr routine.
2. Put a "0" in the getattr slot in the type object.
3. Use the "methods" slot. [*]
This is not documented anywhere, so I needed to "diff" modules between
2.6 and 3.0 trees :-(
But I have some code I don't know how to "upgrade". Can you possibly
help me?
The full sourcecode:
"""
static PyObject*
DBEnv_getattr(DBEnvObject* self, char *name)
{
~ if (!strcmp(name, "db_home")) {
~ const char *home = NULL;
~ CHECK_ENV_NOT_CLOSED(self);
#if (DBVER >= 42)
~ self->db_env->get_home(self->db_env, &home);
#else
~ home=self->db_env->db_home;
#endif
~ if (home == NULL) {
~ RETURN_NONE();
~ }
~ return PyBytes_FromString(home);
~ }
~ return Py_FindMethod(DBEnv_methods, (PyObject* )self, name);
}
"""
What can I do?.
Moreover, is this "Py_FindMethod" removal strategy valid for old Python
releases?. I need to support Python 2.3 and up.
[*] Using this change, the code doesn't work :-(. Compiling under
Python2.6 I get a lot of errors: "AttributeError: 'DB' object has no
attribute 'XXX'."
Example of "diff" I'm doing:
1. Delete the "DBSequence_getattr" routine.
2. Change the DBSequence_Type as:

"""
What am I doing wrong?.
Thanks in advance.
PS: Four hours of hard working and bsddb "almost" compiles under
Python3.0b2!.
