From ea3f7e598c8f1171f0bd02da777dc526cdb8424d Mon Sep 17 00:00:00 2001 From: Michael Forney Date: Tue, 23 Jun 2020 13:56:58 -0700 Subject: [PATCH 1/2] revision: use repository from rev_info when parsing commits This is needed when repo_init_revisions() is called with a repository that is not the_repository to ensure appropriate repository is used in repo_parse_commit_internal(). If the wrong repository is used, a fatal error is the commit-graph machinery occurs: fatal: invalid commit position. commit-graph is likely corrupt Since revision.c was the only user of the parse_commit_gently compatibility define, remove it from commit.h.

However, prepare_submodule_summary() initializes the rev_info with the_repository, so we end up parsing the commit in the wrong repository. This results in a fatal error in parse_commit_in_graph(), since the passed item does not belong to the repository's commit graph.
