[Python-Dev] Remaining decisions on PEP 471 -- os.scandir() (original) (raw)

Sorry, I don't remember who but someone proposed to add the followsymlinks parameter in scandir() directly. If the parameter is added to methods, there is no such issue.

Yeah, I think having the DirEntry methods do different things depending on how scandir() was called is a really bad idea. It seems you're agreeing with this?

Again: remove any garantee about the cache in the definitions of methods, instead copy the doc from os.path and os. Add a global remark saying that most methods don't need any syscall in general, except for symlinks (with followsymlinks=True).

I'm not sure I follow this -- surely it has to be documented that the values of DirEntry.is_X() and DirEntry.stat() are cached per entry, in contrast to os.path.isX()/os.stat()?

I don't mind a global remark about not needing syscalls, but I do think it makes sense to make it explicit -- that is_X() almost never need syscalls, whereas stat() does only on POSIX but is free on Windows (except for symlinks).
