[Lldb-commits] [PATCH] Move ConnectionFileDescriptor to posix-subfolder in preparation for implementing on Windows

[Zachary Turner]

Good question.  Logically it seems a little too high level for Host to me.
Conceptually speaking, CFD is just a wrapper around one of any number of
host primitives.  For example, it's a wrapper around a file, or a socket,
or a pipe, etc.  It just allows you to treat all those things using the
same interface.  Host seems more appropriate for providing lower-level
primitives.  It's kind of a grey area here though, because the
implementation of CFD uses select(), which doesn't lend itself to a nice
port on Windows, basically the whole thing has to be re-written.

I brainstormed ways of lowering a select-like abstraction into Host so that
CFD could just be implemented without any platform specific stuff, but it's
not that easy since the semantics have some subtle differences that make it
difficult to present a generic interface.
