t1450-fsck.sh does not have a test that checks fsck's behavior when a packfile is invalid. It does have a test for when an object in a packfile is invalid, but in that test, the packfile itself is valid. Add such a test. Signed-off-by: Jonathan Tan <jonathantanmy@xxxxxxxxxx> --- I think the existing packfile corruption test (t5303) is good enough that we would notice such things, but just in case we want to test fsck specifically, here's a patch. --- t/t1450-fsck.sh | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/t/t1450-fsck.sh b/t/t1450-fsck.sh index bb89e1a5d..4087150db 100755 --- a/t/t1450-fsck.sh +++ b/t/t1450-fsck.sh @@ -608,6 +608,22 @@ test_expect_success 'fsck errors in packed objects' ' ! grep corrupt out ' +test_expect_success 'fsck fails on corrupt packfile' ' + hsh=$(git commit-tree -m mycommit HEAD^{tree}) && + pack=$(echo $hsh | git pack-objects .git/objects/pack/pack) && + + # Corrupt the first byte of the first object.
