From de372b1b46d91ffdcd6eb6e324cb8b586c99c539 Mon Sep 17 00:00:00 2001 From: Eric Sunshine Date: Tue, 17 Sep 2013 03:06:17 -0400 Subject: [PATCH] dir: revert work-around for retired dangerous behavior directory_exists_in_index_icase() dangerously assumed that it could access one character beyond the end of its directory argument, and that that character would unconditionally be '/'. 2eac2a4c (ls-files -k: a directory only can be killed if the index has a non-directory, 2013-08-15) added a caller which did not respect this undocumented assumption, and 680be044 (dir.c::test_one_path(): work around directory_exists_in_index_icase() breakage, 2013-08-23) added a work-around which temporarily appends a '/' before invoking directory_exists_in_index_icase(). Since the dangerous behavior of directory_exists_in_index_icase() has been eliminated, the work-around is now redundant, so retire it (but not the tests added by the same commit).
