From 31f5256c82a36edea3ea2f91e5171e3472878915 Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Tue, 28 May 2019 08:19:07 -0700 Subject: [PATCH] sha1-file: split OBJECT_INFO_FOR_PREFETCH The OBJECT_INFO_FOR_PREFETCH bitflag was added to sha1-file.c in 0f4a4fb1 (sha1-file: support OBJECT_INFO_FOR_PREFETCH, 2019-03-29) and is used to prevent the fetch_objects() method when enabled. However, there is a problem with the current use. The definition of OBJECT_INFO_FOR_PREFETCH is given by adding 32 to OBJECT_INFO_QUICK. This is clearly stated above the definition (in a comment) that this is so OBJECT_INFO_FOR_PREFETCH implies OBJECT_INFO_QUICK. The problem is that using "flag & OBJECT_INFO_FOR_PREFETCH" means that OBJECT_INFO_QUICK also implies OBJECT_INFO_FOR_PREFETCH. Split out the single bit from OBJECT_INFO_FOR_PREFETCH into a new OBJECT_INFO_SKIP_FETCH_OBJECT as the single bit and keep OBJECT_INFO_FOR_PREFETCH as the union of two flags. This allows a clearer use of flag checking while also keeping the implication of OBJECT_INFO_QUICK.
