In the `midx.c` file, there are multiple usages of `the_repository` and `the_hash_algo` within static functions of the file. Some of the usages can be simply swapped out with the available `repository` struct. While some of them can be swapped out by passing the repository to the required functions.
This leaves out only some other usages of `the_repository` and `the_hash_algo` in the file in non-static functions, which we'll tackle in upcoming commits.
