t6301: new tests of for-each-ref error handling
Add tests that for-each-ref correctly reports broken loose reference files and references that point at missing objects. In fact, two of these tests fail, because (1) NULL_SHA1 is not recognized as an invalid reference value, and (2) for-each-ref doesn't respect REF_ISBROKEN. Fixes to come. Note that when for-each-ref is run with a --format option that doesn't require the object to be looked up, then we should still notice if a loose reference file is corrupt or contains NULL_SHA1, but we don't notice if it points at a missing object because we don't do an object lookup. This is OK. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>
