[PATCH v3 40/53] http-push: convert process_ls_object and descendants to object_id

From
brian m. carlson <sandals@crustytoothpaste.net>
Date
May 6, 2017, 22:10 UTC
Message-ID
<20170506221038.296722-41-sandals@crustytoothpaste.net>
In-Reply-To
<20170506221038.296722-1-sandals@crustytoothpaste.net>

Rename one function to reflect that it now uses struct object_id. This conversion is a prerequisite for converting parse_object.

Note that while the use of a buffer that is exactly forty bytes long looks questionable, get_oid_hex reads exactly the right number of bytes and does not require the data to be NUL-terminated.
