[New-bugs-announce] [issue17899] os.listdir() leaks FDs if invoked on FD pointing to a non-directory

[Evgeny Kapun]

New submission from Evgeny Kapun:

When called with a file descriptor as an argument, os.listdir() duplicates it to pass to fdopendir(3). If this call fails, the new file descriptor is not closed, which leads to file descriptor leak.
