[PATCH 1/1] ci: add optional test variables

From: Derrick Stolee <dstolee@microsoft.com>

The commit-graph and multi-pack-index features introduce optional data structures that are not required for normal Git operations. It is important to run the normal test suite without them enabled, but it is helpful to also run the test suite using them.

Our continuous integration scripts include a second test stage that runs with optional GIT_TEST_* variables enabled. Add the following two variables to that stage:

  GIT_TEST_COMMIT_GRAPH
  GIT_TEST_MULTI_PACK_INDEX

This will slow down the operation, as we build a commit-graph file after every 'git commit' operation and build a multi-pack-index during every 'git repack' operation. However, it is important that future changes are compatible with these features.
