t/unit-tests: implement clar specific oid helper functions

2025-02-25T18:31:22Z

`get_oid_arbitrary_hex()` and `init_hash_algo()` are both required for oid-related tests to run without errors. In the current implementation, both functions are defined and declared in the `t/unit-tests/lib-oid.{c,h}` which is utilized by oid-related tests in the homegrown unit tests structure. Adapt functions in lib-oid.{c,h} to use clar. Both these functions become available for oid-related test files implemented using the clar testing framework, which requires them. This will be used by subsequent commits. Mentored-by: Patrick Steinhardt Signed-off-by: Seyi Kuforiji Signed-off-by: Junio C Hamano

t: port helper/test-oid-array.c to unit-tests/t-oid-array.c

2024-09-02T03:43:38Z

helper/test-oid-array.c along with t0064-oid-array.sh test the oid-array.h API, which provides storage and processing efficiency over large lists of object identifiers. Migrate them to the unit testing framework for better runtime performance and efficiency. As we don't initialize a repository in these tests, the hash algo that functions like oid_array_lookup() use is not initialized, therefore call repo_set_hash_algo() to initialize it. And init_hash_algo():lib-oid.c can aid in this process, so make it public.

t/: migrate helper/test-oidtree.c to unit-tests/t-oidtree.c

2024-06-12T20:33:20Z

helper/test-oidtree.c along with t0069-oidtree.sh test the oidtree.h library, which is a wrapper around crit-bit tree. Migrate them to the unit testing framework for better debugging and runtime performance. Along with the migration, add an extra check for oidtree_each() test, which showcases how multiple expected matches can be given to check_each() helper. To achieve this, introduce a new library called 'lib-oid.h' exclusively for the unit tests to use. It currently mainly includes utility to generate object_id from an arbitrary hex string (i.e. '12a' -> '12a0000000000000000000000000000000000000'). This also handles the hash algo selection based on GIT_TEST_DEFAULT_HASH. This library will also be helpful when we port other unit tests such as oid-array, oidset etc. Helped-by: Junio C Hamano Mentored-by: Christian Couder Mentored-by: Kaartic Sivaraam Signed-off-by: Ghanshyam Thakkar [jc: small fixlets squashed in] Signed-off-by: Junio C Hamano
