From 1f27522d8c651db5d254d352377051d7071edcdc Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C4=90o=C3=A0n=20Tr=E1=BA=A7n=20C=C3=B4ng=20Danh?= Date: Wed, 25 Mar 2020 22:06:14 +0700 Subject: [PATCH] t4061: use POSIX compliant regex(7) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit BRE interprets `+` literally, and `\+` is undefined for POSIX BRE, from: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html#tag_09_03_02 > The interpretation of an ordinary character preceded > by an unescaped ( '\\' ) is undefined, except for: > - The characters ')', '(', '{', and '}' > - The digits 1 to 9 inclusive > - A character inside a bracket expression This test is failing with busybox sed, the default sed of Alpine Linux We have 2 options here: - Using literal `+` because BRE will interpret it as-is, or - Using character class `[+]` to defend against a sed that expects ERE ERE-expected sed is theoretical at this point, but we haven't found it, yet. And, we may run into other problems with that sed. Let's go with first option and fix it later if that sed could be found.
