This PR fixes the issue when importlib is being used with named arguments outlined in the #694.
Following cases are found:
importlib.import_module("foo", "bar.baz")
results incall_args = ["foo", "bar.baz"]
andcall_keywords = {}
importlib.import_module("foo", package="bar.baz")
results incall_args = ["foo"]
andcall_keywords = {"package": "bar.baz"}
importlib.import_module(name="foo", package="bar.baz")
results incall_args = []
andcall_keywords = {"name": "foo", "package": "bar.baz"}
The simplest approach is to use
context.call_args_count
and if the call_args_count is larger than 0, callcall_args[0]
which will choosefoo
. If call_args_count is equal to 0 then we need to choosename
from the call_keywords.I haven't found previous tests covering the blacklisting importlib functionality so if anyone more fluent in the codebase could point me in the direction of where this should be tested I can add the test cases for this functionality.
