Patrick Steinhardt 983e627d 2017-06-13T11:38:59 tests: odb: use correct OID length The `search_object` function takes the OID length as one of its parameters, where its maximum length is `GIT_OID_HEXSZ`. The `exists` function of the fake backend used `GIT_OID_RAWSZ` though, leading to only the first half of the OID being used when finding the correct object.
Patrick Steinhardt c4cbb3b1 2017-06-13T11:38:14 tests: odb: have the fake backend detect ambiguous prefixes In order to be able to test the ODB prefix functions, we need to be able to detect ambiguous prefixes in case multiple objects with the same prefix exist in the fake ODB. Extend `search_object` to detect ambiguous queries and have callers return its error code instead of always returning `GIT_ENOTFOUND`.
Patrick Steinhardt 6e010bb1 2017-06-12T15:43:56 tests: odb: allow passing fake objects to the fake backend Right now, the fake backend is quite restrained in the way how it works: we pass it an OID which it is to return later as well as an error code we want it to return. While this is sufficient for existing tests, we can make the fake backend a little bit more generic in order to allow us testing for additional scenarios. To do so, we change the backend to not accept an error code and OID which it is to return for queries, but instead a simple array of OIDs with their respective blob contents. On each query, the fake backend simply iterates through this array and returns the first matching object.
Patrick Steinhardt 2add34d0 2017-06-12T14:53:46 tests: odb: move fake backend into its own file The fake backend used by the test suite `odb::backend::nonrefreshing` is useful to have some low-level tests for the ODB layer. As such, we move the implementation into its own `backend_helpers` module.
