From ec7fc0b1a46c5a352532ea3f29c5663752fd8ac6 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 25 Nov 2009 02:56:54 -0800 Subject: [PATCH] builtin-apply.c: pay attention to -p when determining the name The patch structure has def_name component that is used to validate the sanity of a "diff --git" patch by checking pathnames that appear on the patch header lines for consistency. The git_header_name() function is used to compute this out of "diff --git a/... b/..." line, but the code always stripped one level of prefix (i.e. "a/" and "b/"), without paying attention to -p option. Code in find_name() function that parses other lines in the patch header (e.g. "--- a/..." and "+++ b/..." lines) however did strip the correct number of leading paths prefixes, and the sanity check between these computed values failed. Teach git_header_name() to honor -p option like find_name() function does. Found and reported by Steven J. Murdoch who also wrote tests.
