From 9553aa0f6c844085b3fbf05da5440dd7096dd764 Mon Sep 17 00:00:00 2001 From: Victoria Dye Date: Mon, 8 Aug 2022 19:07:51 +0000 Subject: cache.h: create 'index_name_pos_sparse()' Add 'index_name_pos_sparse()', which behaves the same as 'index_name_pos()', except that it does not expand a sparse index to search for an entry inside a sparse directory. 'index_entry_exists()' was originally implemented in 20ec2d034c (reset: make sparse-aware (except --mixed), 2021-11-29) as an alternative to 'index_name_pos()' to allow callers to search for an index entry without expanding a sparse index. However, that particular use case only required knowing whether the requested entry existed, so 'index_entry_exists()' does not return the index positioning information provided by 'index_name_pos()'. This patch implements 'index_name_pos_sparse()' to accommodate callers that need the positioning information of 'index_name_pos()', but do not want to expand the index.
