Subject: [PATCH 1/3] rebase: introduce --reschedule-failed-exec
Date: Mon, 10 Dec 2018 11:04:58 -0800 (PST) [thread overview]
Message-ID: <05d8792d12e692eeefa0021e8686b7211a055593.1544468695.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.90.git.gitgitgadget@gmail.com>
From: Johannes Schindelin <johannes.schindelin@gmx.de>
A common use case for the `--exec` option is to verify that each commit
in a topic branch compiles cleanly, via `git rebase -x make <base>`.
However, when an `exec` in such a rebase fails, it is not re-scheduled,
which in this instance is not particularly helpful.
Let's offer a flag to reschedule failed `exec` commands.
Based on an idea by Paul Morelle.
