Subject: [PATCH v4 1/1] range-diff: treat notes like `log`
Date: Tue, 19 Sep 2023 20:05:32 +0200 [thread overview]
Message-ID: <244e102cc4693bb6291e03cffea6df05cdb29df3.1695144790.git.code@khaugsbakk.name> (raw)
In-Reply-To: <cover.1695144790.git.code@khaugsbakk.name>
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=<custom>` 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[=<ref>]` 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.
§ Root cause
8cf51561d1e (range-diff: fix a crash in parsing git-log output,
2020-04-15) added `--notes` in order to deal with a side-effect of
`--pretty=medium`:
> To fix this explicitly set the output format of the internally executed
> `git log` with `--pretty=medium`. Because that cancels `--notes`, add
> explicitly `--notes` at the end.
§ 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).
