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. Signed-off-by: Derrick Stolee <dstolee@microsoft.com>

Our CI scripts include a step to run the test suite with certain optional variables enabled. Now that all branches should build and have tests succeed with GIT_TEST_COMMIT_GRAPH and GIT_TEST_MULTI_PACK_INDEX enabled, add those variables to that stage.
Note: the GIT_TEST_MULTI_PACK_INDEX variable has not merged all the way down, so will be ignored if this series is merged faster than that one. However, it is safe to make these changes orthogonally as all (known) test breaks with GIT_TEST_MULTI_PACK_INDEX=1 are fixed in the topic that introduces the variable.
I also created a build definition on Azure Pipelines that runs the test suite with different subsets of the test variables, split by the following types:
These builds are found at [1]. There are benefits to testing the variables all together but also separately. I didn't want to create new stages in the CI scripts to avoid consuming extra resources.
This series is based on js/vsts-ci to avoid conflicts with that series, but is not necessarily a hard dependence.
Thanks,
