From ed4958477b28a1dd28597e40094e9a202a870379 Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Fri, 24 Sep 2021 15:39:05 +0000 Subject: [PATCH] dir: fix pattern matching on dirs Within match_pathname(), one successful matching category happens when the pattern is equal to its non-wildcard prefix. At this point, we have checked that the input 'pathname' matches the pattern up to the prefix length, and then we subtraced that length from both 'patternlen' and 'namelen'. In the case of a directory match, this prefix match should be sufficient. However, the success condition only cared about _exact_ equality here. Instead, we should allow any path that agrees on this prefix in the case of PATTERN_FLAG_MUSTBEDIR. This case was not tested before because of the way unpack_trees() would match a parent directory before visiting the contained paths. This approach is changing, so we must change this comparison.
