Thanks, that actually works for one of the cases we have (there are
others that use globs which cannot be solved quite that simply, but for
now I'm just listing files explicitly instead).
However, I'm not sure that "globs aren't supported". The commit I
referenced clearly tried to make that work (better), it also "works" in
the sense of unpacking the expected things when building from scratch -
there's even
def test_local_wildcard(self):
tree = self.fetchUnpack(['file://a', 'file://dir/*'])
self.assertEqual(tree, ['a', 'dir/c', 'dir/d', 'dir/subdir/e'])
in bitbake/lib/bb/tests/fetch.py. And the two upstream recipes
connman-gnome_0.7.bb and matchbox-desktop_2.2.bb both use that exact
pattern.
So either
- this is a plain bug in the signature computation,
- documentation lacks a big fat warning that using globs in file://
should be avoided unless one has a fetish for tracking down bugs due to
confused sstate, or
- all code that makes glob patterns work should be ripped out so that it
is indeed not supported, thus eliminating this footgun.
