def __init__(self, files): (source)

Parameters
files:`Set[str]`	Undocumented

def init_under_package_root(self, file): (source)

overrides mypy.fscache.FileSystemCache.init_under_package_root

Is this path an __init__.py under a package root?

This is used to detect packages that don't contain __init__.py files, which is needed to support Bazel. The function should only be called for non-existing files.

It will return True if it refers to a __init__.py file that Bazel would create, so that at runtime Python would think the directory containing it is a package. For this to work you must pass one or more package roots using the --package-root flag.

As an exceptional case, any directory that is a package root itself will not be considered to contain a __init__.py file. This is different from the rules Bazel itself applies, but is necessary for mypy to properly distinguish packages from other directories.

See https://docs.bazel.build/versions/master/be/python.html, where this behavior is described under legacy_create_init.
