This PR decides to explicitly diverge the LiteBox core file system semantics from POSIX. It is part of the longer-term plan to move away from the
OFlagsand use a more broader-applicable abstraction there anyways. Roughly, POSIX requires thatopenofO_WRONLYor such on a directory should return anEISDIR. However, this is a shim-level concern, and the core should not be concerned with this sort of semantics. Thus, I've moved this decision into the shim.
