From 0f64bfa9567f697d6152ef9ea937d4b573029a08 Mon Sep 17 00:00:00 2001 From: Clemens Buchacher Date: Mon, 1 Aug 2011 23:19:58 +0200 Subject: ls-files: fix pathspec display on error The following sequence of commands reveals an issue with error reporting of relative paths: $ mkdir sub $ cd sub $ git ls-files --error-unmatch ../bbbbb error: pathspec 'b' did not match any file(s) known to git. $ git commit --error-unmatch ../bbbbb error: pathspec 'b' did not match any file(s) known to git. This bug is visible only if the normalized path (i.e., the relative path from the repository root) is longer than the prefix. Otherwise, the code skips over the normalized path and reads from an unused memory location which still contains a leftover of the original command line argument. So instead, use the existing facilities to deal with relative paths correctly. Also fix inconsistency between "checkout" and "commit", e.g. $ cd Documentation $ git checkout nosuch.txt error: pathspec 'Documentation/nosuch.txt' did not match... $ git commit nosuch.txt error: pathspec 'nosuch.txt' did not match... by propagating the prefix down the codepath that reports the error.
