The final leg of SHA-256 transition. * bc/sha-256-part-3: (39 commits) t: remove test_oid_init in tests docs: add documentation for extensions.objectFormat ci: run tests with SHA-256 t: make SHA1 prerequisite depend on default hash t: allow testing different hash algorithms via environment t: add test_oid option to select hash algorithm repository: enable SHA-256 support by default setup: add support for reading extensions.objectformat bundle: add new version for use with SHA-256 builtin/verify-pack: implement an --object-format option http-fetch: set up git directory before parsing pack hashes t0410: mark test with SHA1 prerequisite t5308: make test work with SHA-256 t9700: make hash size independent t9500: ensure that algorithm info is preserved in config t9350: make hash size independent t9301: make hash size independent t9300: use $ZERO_OID instead of hard-coded object ID t9300: abstract away SHA-1-specific constants t8011: make hash size independent ...
