In t7450 we check that both verify_path() and fsck catch malformed
.gitmodules entries in trees. However, we don't check that we catch
filesystem-equivalent forms of these (e.g., ".GITMOD~1" on Windows).
Our name-matching functions are exercised well in t0060, but there's
nothing to test that we correctly call the matching functions from the
actual fsck and verify_path() code.
So instead of testing just .gitmodules, let's repeat our tests for a few
basic cases. We don't need to be exhaustive here (t0060 handles that),
but just make sure we hit one name of each type.
Besides pushing the tests into a function that takes the path as a
parameter, we'll need to do a few things:
- adjust the directory name to accommodate the tests running multiple
times
- set core.protecthfs for index checks. Fsck always protects all types
by default, but we want to be able to exercise the HFS routines on
every system. Note that core.protectntfs is already the default
these days, but it doesn't hurt to explicitly label our need for it.
- we'll also take the filename ("gitmodules") as a parameter. All
calls use the same name for now, but a future patch will extend this
to handle other .gitfoo files. Note that our fake-content symlink
destination is somewhat .gitmodules specific. But it isn't necessary
for other files (which don't do a content check). And it happens to
be a valid attribute and ignore file anyway.
