We have two overlapping tests for checking the behavior of "ls-remote --symref" when filtering output. The first test checks that using "--heads" will omit the symref for HEAD (since we don't print anything about HEAD at all), but still prints other symrefs. This has been marked as expecting failure since it was added in99c08d4eb2(ls-remote: add support for showing symrefs, 2016-01-19). That's because back then, we only had the v0 protocol, and it only reported on the HEAD symref, not others. But these days we have v2, which does exactly what the test wants. It would even have started unexpectedly passing when we switched to v2 by default, except thatb2f73b70b2(t5512: compensate for v0 only sending HEAD symrefs, 2019-02-25) over-zealously marked it to run only in v0 mode. So let's run it with both protocol versions, and adjust the expected output for each. It passes in v2 without modification. In v0 mode, we'll drop the extra symref, but this is still testing something useful: it ensures that we do omit HEAD. The test after this checks "--heads" again, this time using the expected v0 output. That's now redundant. It also checks that limiting with a pattern like "refs/heads/*" works similarly, but that's redundant with a test earlier in the script which limits by HEAD (again, back then the "HEAD" test was less interesting because there were no other symrefs to omit, but in a modern v2 world, there are). So we can just delete that second test entirely. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
