From 155986b49b52b9b5910edc0fd56ba46f0f1bed22 Mon Sep 17 00:00:00 2001 From: Kristoffer Haugsbakk Date: Thu, 25 Sep 2025 19:07:36 +0200 Subject: format-patch: handle range-diff on notes correctly for single patches (The two next paragraphs are taken from the previous commit.) git-format-patch(1) supports Git notes by showing them beneath the patch/commit message, similar to git-log(1). The command also supports showing those same notes ref names in the range diff output. Note *the same* ref names; any Git notes options or configuration variables need to be handed off to the range-diff machinery. This works correctly in the case when the range diff is on the cover letter. But it does not work correctly when the output is a single patch with an embedded range diff. Concretely, git-format-patch(1) needs to pass `--[no-]notes` options on to the range-diff subprocess in `range-diff.c`. Range diffs for single- commit series are handled in `log-tree.c`. But `log-tree.c` had no access to any `log_arg` variable before we added it to `rev_info` in the previous commit. Use that new struct member to fix this inconsistency.
