Subject: [PATCH RFC v2 10/19] rebase -i: Do not die in do_pick
Date: Wed, 2 Jul 2014 19:48:02 +0200 [thread overview]
Message-ID: <50ca26dbebbc291af5110770665c283375345bbd.1404323078.git.bafain@gmail.com> (raw)
In-Reply-To: <cover.1404323078.git.bafain@gmail.com>
Since `do_pick` might be executed in a sub-shell (a modified author
environment for instance), calling `die` in `do_pick` has no effect
but exiting the sub-shell with a failure exit status. The
git-rebase--interactive script is not terminated. Moreover, if
`do_pick` is called while a squash or fixup is in effect,
`die_with_patch` will discard `$squash_msg` as commit message.
Lastly, after a `die` in `do_pick` `do_next` has no chance to
reschedule tasks that failed before changes could be applied.
Indicate an error in `do_pick` using return statements and properly
kill the script at the call sites. Although possible in principle,
the issued error messages are no more indicating whether `do_pick`
failed while applying or while committing the changes. This reduces
code complexity at the call site and does not matter from a user's
point of view because a glance at the index reveals whether there are
conflicts or not and in-depth troubleshooting is still possible using
the `--verbose` option.
Remove the commit message title argument from `do_pick`'s interface,
which has become unused.
