Subject: [PATCH v10 11/14] convert: make apply_filter() adhere to standard Git error handling
Date: Sat, 8 Oct 2016 13:25:27 +0200 [thread overview]
Message-ID: <20161008112530.15506-12-larsxschneider@gmail.com> (raw)
In-Reply-To: <20161008112530.15506-1-larsxschneider@gmail.com>
From: Lars Schneider <larsxschneider@gmail.com>
apply_filter() returns a boolean that tells the caller if it
"did convert or did not convert". The variable `ret` was used throughout
the function to track errors whereas `1` denoted success and `0`
failure. This is unusual for the Git source where `0` denotes success.
Rename the variable and flip its value to make the function easier
readable for Git developers.
