[Python-Dev] Updates to PEP 471, the os.scandir() proposal (original) (raw)

Only exposing what the OS provides for free will make the API too difficult to use in the common case. But is there a nice way to expand the API that will allow the user who is trying to avoid extra expense know what information is already available?

Even if the initial version doesn't have a way to check what information is there for free, ensuring there is a clean way to add this in the future would be really nice.

We could easily add ".had_type" and ".had_lstat" properties (not sure on the names), that would be true if the is_X information and lstat information was fetched, respectively. Basically both would always be True on Windows, but on POSIX only had_type would be True d_type is present and != DT_UNKNOWN.

I don't feel this is actually necessary, but it's not hard to add.

Thoughts?
