From ab6f79d8df7c7799ed38229eb56811fda36853ae Mon Sep 17 00:00:00 2001 From: shejialuo Date: Thu, 8 Aug 2024 19:27:17 +0800 Subject: refs: set up ref consistency check infrastructure The "struct ref_store" is the base class which contains the "be" pointer which provides backend-specific functions whose interfaces are defined in the "ref_storage_be". We could reuse this polymorphism to define only one interface. For every backend, we need to provide its own function pointer. The interfaces defined in the `ref_storage_be` are carefully structured in semantic. It's organized as the five parts: 1. The name and the initialization interfaces. 2. The ref transaction interfaces. 3. The ref internal interfaces (pack, rename and copy). 4. The ref filesystem interfaces. 5. The reflog related interfaces. To keep consistent with the git-fsck(1), add a new interface named "fsck_refs_fn" to the end of "ref_storage_be". This semantic cannot be grouped into any above five categories. Explicitly add blank line to make it different from others. Last, implement placeholder functions for each ref backends.
