Hi, It looks to me that the import system of Python will ignore invalid directories and cache the result in memory.
For example, the following code: paste here: https://bpaste.net/show/b144deb42620 #!/usr/bin/env python3 import sysimport osimport shutil sys.path.append("./test")shutil.rmtree("./test", ignore_errors=True) try: import fooexcept ImportError: os.mkdir("./test") with open("./test/foo.py", "w") as f: f.write("print(3)") import foo the second import foo will fail even though it's there. This is because when doing the first import foo, the directory .test doesn't exist, and Python ignores that directory forever. I am interested in the c side implementation of this "ignoring" part. Any body help me to pinpoint the exact c source location? Thanks. -- 吾輩は猫である。ホームーページはhttps://introo.me <http://introo.me>。
