From 2e0d30d928dbb8899ebae749ceeb257e634d57f7 Mon Sep 17 00:00:00 2001 From: Kristoffer Haugsbakk Date: Tue, 19 Sep 2023 22:26:50 +0200 Subject: [PATCH] range-diff: treat notes like `log` MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently, `range-diff` shows the default notes if no notes-related arguments are given. This is also how `log` behaves. But unlike `range-diff`, `log` does *not* show the default notes if `--notes=` are given. In other words, this: git log --notes=custom is equivalent to this: git log --no-notes --notes=custom While: git range-diff --notes=custom acts like this: git log --notes --notes-custom This can’t be how the user expects `range-diff` to behave given that the man page for `range-diff` under `--[no-]notes[=]` says: > This flag is passed to the `git log` program (see git-log(1)) that > generates the patches. This behavior also affects `format-patch` since it uses `range-diff` for the cover letter. Unlike `log`, though, `format-patch` is not supposed to show the default notes if no notes-related arguments are given.[1] But this promise is broken when the range-diff happens to have something to say about the changes to the default notes, since that will be shown in the cover letter. Remedy this by introducing `--show-notes-by-default` that `range-diff` can use to tell the `log` subprocess what to do. § Authors • Fix by Johannes • Tests by Kristoffer † 1: See e.g. 66b2ed09c2 (Fix "log" family not to be too agressive about showing notes, 2010-01-20).
