From cbd53a2193d11e83b5bad2c3514bd1603074bc36 Mon Sep 17 00:00:00 2001 From: Stefan Beller Date: Tue, 15 May 2018 16:42:15 -0700 Subject: object-store: move object access functions to object-store.h This should make these functions easier to find and cache.h less overwhelming to read. In particular, this moves: - read_object_file - oid_object_info - write_object_file As a result, most of the codebase needs to #include object-store.h. In this patch the #include is only added to files that would fail to compile otherwise. It would be better to #include wherever identifiers from the header are used. That can happen later when we have better tooling for it.
