Subject: [PATCH 06/29] bisect: libify `exit_if_skipped_commits` to `error_if_skipped*` and its dependents
Date: Mon, 20 Jan 2020 15:37:37 +0100 [thread overview]
Message-ID: <20200120143800.900-7-mirucam@gmail.com> (raw)
In-Reply-To: <20200120143800.900-1-mirucam@gmail.com>
From: Pranit Bauva <pranit.bauva@gmail.com>
Since we want to get rid of git-bisect.sh it would be necessary to
convert those exit() calls to return statements so that errors can be
reported.
Emulate try catch in C by converting `exit(<positive-value>)` to
`return <negative-value>`. Follow POSIX conventions to return
<negative-value> to indicate error.
Modify `cmd_bisect_helper()` to handle these negative returns.
Turn `exit()` to `return` calls in `exit_if_skipped_commits()` and rename
the method to `error_if_skipped_commits()`.
Handle this return in dependant function `bisect_next_all()`.
