From 24876ebf68baf90075dad5ca3acba8a305f308d4 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Wed, 28 Feb 2024 09:44:09 +0000 Subject: commit-reach(repo_in_merge_bases_many): report missing commits Some functions in Git's source code follow the convention that returning a negative value indicates a fatal error, e.g. repository corruption. Let's use this convention in `repo_in_merge_bases()` to report when one of the specified commits is missing (i.e. when `repo_parse_commit()` reports an error). Also adjust the callers of `repo_in_merge_bases()` to handle such negative return values. Note: As of this patch, errors are returned only if any of the specified merge heads is missing. Over the course of the next patches, missing commits will also be reported by the `paint_down_to_common()` function, which is called by `repo_in_merge_bases_many()`, and those errors will be properly propagated back to the caller at that stage.
