Is there a recommended strategy to get do_fetch to invalidate on directory
path changes in paths pointed to by file:// URLs in SRC_URI?
Example:
SRC_URI += "file://src;subdir=${S}"
A file at src/foo/bar/baz is recognized just fine. But then a directory
change to something like src/foo/bar2/baz is not recognized and does not
invalidate any tasks in subsequent builds.
Use case is a recipe that has a fair bit of metadata that is not even
remotely amenable to the typical flat layout expected of a set of patches.
..Ch:W..
P.S. I attempted to do this with an event handler that was run when
bb.event.RecipePreFinalise is is fired. It would compare directory trees
and set do_fetch[nostamp] = "1" to invalidate the fetcher task. But I got
really spotty behavior. It seems like event handlers are cached like tasks.
