[PATCH v3 06/53] bundle: convert to struct object_id

From
brian m. carlson <sandals@crustytoothpaste.net>
Date
May 6, 2017, 22:09 UTC
Message-ID
<20170506221038.296722-7-sandals@crustytoothpaste.net>
In-Reply-To
<20170506221038.296722-1-sandals@crustytoothpaste.net>

Convert the bundle code, plus the sole external user of struct ref_list_entry, to use struct object_id. Include cache.h from within bundle.h to provide the definition. Convert some of the hash parsing code to use parse_oid_hex to avoid needing to hard-code constant values.
