From 19fc5e84a70e0dc6d6b3a279fa549b4e522ee33b Mon Sep 17 00:00:00 2001 From: Jonathan Tan Date: Wed, 21 Jun 2017 17:40:18 -0700 Subject: [PATCH] sha1_file: rename LOOKUP_UNKNOWN_OBJECT The LOOKUP_UNKNOWN_OBJECT flag was introduced in commit 46f0344 ("sha1_file: support reading from a loose object of unknown type", 2015-05-03) in order to support a feature in cat-file subsequently introduced in commit 39e4ae3 ("cat-file: teach cat-file a '--allow-unknown-type' option", 2015-05-03). Despite its name and location in cache.h, this flag is used neither in read_sha1_file_extended() nor in any of the lookup functions, but used only in sha1_object_info_extended(). Therefore rename this flag to OBJECT_INFO_ALLOW_UNKNOWN_TYPE, taking the name of the cat-file flag that invokes this feature, and move it closer to the declaration of sha1_object_info_extended(). Also add documentation for this flag. OBJECT_INFO_ALLOW_UNKNOWN_TYPE is defined to 2, not 1, to avoid conflicting with LOOKUP_REPLACE_OBJECT. Avoidance of this conflict is necessary because sha1_object_info_extended() supports both flags.
