From 17925e0602983b1a1dbdd418c2fc2c70ca5faf5b Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Tue, 1 Mar 2022 19:48:29 +0000 Subject: t5318: extract helpers to lib-commit-graph.sh The graph_git_behavior helper is useful for testing that certain Git commands behave the same when using the commit-graph and when not using the commit-graph. Extract it to a new lib-commit-graph.sh file for use in new test scripts that will split out from t5318. While doing this extraction, also extract graph_read_expect and the logic for priming the test_oid_cache.
