From 9ad2d5ea71d1470c2fd68b76c36b2ced3612cde3 Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Tue, 30 Mar 2021 13:11:03 +0000 Subject: sparse-index: loose integration with cache_tree_verify() The cache_tree_verify() method is run when GIT_TEST_CHECK_CACHE_TREE is enabled, which it is by default in the test suite. The logic must be adjusted for the presence of these directory entries. For now, leave the test as a simple check for whether the directory entry is sparse. Do not go any further until needed. This allows us to re-enable GIT_TEST_CHECK_CACHE_TREE in t1092-sparse-checkout-compatibility.sh. Further, p2000-sparse-operations.sh uses the test suite and hence this is enabled for all tests. We need to integrate with it before we run our performance tests with a sparse-index.
