Subject: [PATCH v2 26/27] attr: push the bare repo check into read_attr()
Date: Mon, 23 Jan 2017 12:35:24 -0800 [thread overview]
Message-ID: <20170123203525.185058-27-bmwill@google.com> (raw)
In-Reply-To: <20170123203525.185058-1-bmwill@google.com>
Push the bare repository check into the 'read_attr()' function. This
avoids needing to have extra logic which creates an empty stack frame
when inside a bare repo as a similar bit of logic already exists in the
'read_attr()' function.
