There are many tests that validate whether 'git pack-objects' works as expected. Instead of duplicating these tests, add a new test environment variable, GIT_TEST_PACK_PATH_WALK, that implies --path-walk by default when specified. This was useful in testing the implementation of the --path-walk implementation, helping to find tests that are overly specific to the default object walk. These include: - t0411-clone-from-partial.sh : One test fetches from a repo that does not have the boundary objects. This causes the path-based walk to fail. Disable the variable for this test. - t5306-pack-nobase.sh : Similar to t0411, one test fetches from a repo without a boundary object. - t5310-pack-bitmaps.sh : One test compares the case when packing with bitmaps to the case when packing without them. Since we disable the test variable when writing bitmaps, this causes a difference in the object list (the --path-walk option adds an extra object). Specify --no-path-walk in both processes for the comparison. Another test checks for a specific delta base, but when computing dynamically without using bitmaps, the base object it too small to be considered in the delta calculations so no base is used. - t5316-pack-delta-depth.sh : This script cares about certain delta choices and their chain lengths. The --path-walk option changes how these chains are selected, and thus changes the results of this test. - t5322-pack-objects-sparse.sh : This demonstrates the effectiveness of the --sparse option and how it combines with --path-walk. - t5332-multi-pack-reuse.sh : This test verifies that the preferred pack is used for delta reuse when possible. The --path-walk option is not currently aware of the preferred pack at all, so finds a different delta base. - t7406-submodule-update.sh : When using the variable, the --depth option collides with the --path-walk feature, resulting in a warning message. Disable the variable so this warning does not appear. I want to call out one specific test change that is only temporary: - t5530-upload-pack-error.sh : One test cares specifically about an "unable to read" error message. Since the current implementation performs delta calculations within the path-walk API callback, a different "unable to get size" error message appears. When this is changed in a future refactoring, this test change can be reverted. Similar to GIT_TEST_NAME_HASH_VERSION, we do not add this option to the linux-TEST-vars CI build as that's already an overloaded build.
