[PATCH 04/24] convert.c: remove an implicit dependency on the_index

From
Nguyễn Thái Ngọc Duy <pclouds@gmail.com>
Date
Aug 13, 2018, 16:14 UTC
Message-ID
<20180813161441.16824-5-pclouds@gmail.com>
In-Reply-To
<20180813161441.16824-1-pclouds@gmail.com>

Make the convert API take an index_state instead of assuming the_index in convert.c. All external call sites are converted blindly to keep the patch simple and retain current behavior. Individual call sites may receive further updates to use the right index instead of the_index.
