From 61e2a70ff26f83f761fa36e0cc16996878d8dd59 Mon Sep 17 00:00:00 2001 From: "brian m. carlson" Date: Sat, 22 Feb 2020 20:17:29 +0000 Subject: hex: add functions to parse hex object IDs in any algorithm There are some places where we need to parse a hex object ID in any algorithm without knowing beforehand which algorithm is in use. An example is when parsing fast-import marks. Add a get_oid_hex_any to parse an object ID and return the algorithm it belongs to, and additionally add parse_oid_hex_any which is the equivalent change for parse_oid_hex. If the object is not parseable, we return GIT_HASH_UNKNOWN.
