Subject: [PATCH v2 2/2] [GSOC] cherry-pick: use better advice message
Date: Tue, 03 Aug 2021 01:16:22 +0000	[thread overview]
Message-ID: <5279bca7a794bd66681d420147e193d2b5415860.1627953383.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1010.v2.git.1627953383.gitgitgadget@gmail.com>

From: ZheNing Hu <adlternative@gmail.com>

In the past, git cherry-pick would print such advice when
there was a conflict:

hint: after resolving the conflicts, mark the corrected paths
hint: with 'git add <paths>' or 'git rm <paths>'
hint: and commit the result with 'git commit'

But in fact, when we want to cherry-pick multiple commits,
we should not use "git commit" after resolving conflicts, which
will make Git generate some errors. We should recommend users to
use `git cherry-pick --continue`, `git cherry-pick --abort`, just
like git rebase does.

This is the improved advice:

hint: Resolve all conflicts manually, mark them as resolved with
hint: "git add/rm <conflicted_files>", then run
hint: "git cherry-pick --continue".
hint: You can instead skip this commit: run "git cherry-pick --skip".
hint: To abort and get back to the state before "git cherry-pick",
hint: run "git cherry-pick --abort".
