Subject: [PATCH 09/18] chainlint.pl: don't require `&` background command to end with `&&`
Date: Thu, 01 Sep 2022 00:29:47 +0000 [thread overview]
Message-ID: <86a718bfa5585c826fc98f8844a52faabb45fa55.1661992197.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1322.git.git.1661992197.gitgitgadget@gmail.com>
From: Eric Sunshine <sunshine@sunshineco.com>
The exit status of the `&` asynchronous operator which starts a command
in the background is unconditionally zero, and the few places in the
test scripts which launch commands asynchronously are not interested in
the exit status of the `&` operator (though they often capture the
background command's PID). As such, there is little value in complaining
about broken &&-chain for a command launched in the background, and
doing so would only make busy-work for test authors. Therefore, take
this special case into account when checking for &&-chain breakage.
