What

Filesystem failures are now sorted into two groups instead of one: the existing out-of-space and handle-exhaustion codes, and a new set of permission codes, so callers can tell "cannot write here" from "disk is full".

Details
  • The new set covers EACCES, EPERM, and EROFS.
Evidence

new Set(["EACCES", "EPERM", "EROFS"])

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
