From d7992421e1a0e3ea5f836d8906e0f8b197fb6c1e Mon Sep 17 00:00:00 2001 From: Matheus Tavares Date: Wed, 15 Jan 2020 23:39:55 -0300 Subject: [PATCH] submodule-config: add skip_if_read option to repo_read_gitmodules() Currently, submodule-config.c doesn't have an externally accessible function to read gitmodules only if it wasn't already read. But this exact behavior is internally implemented by gitmodules_read_check(), to perform a lazy load. Let's merge this function with repo_read_gitmodules() adding a 'skip_if_read' which allows both internal and external callers to access this functionality. This simplifies a little the code. The added option will also be used in the following patch.
