From 76001de031a562a0f350daae381196fa44576eb3 Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Wed, 22 Sep 2021 08:43:20 +0900 Subject: [PATCH] Fix places in TestLib.pm in need of adaptation to the output of Msys perl MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Contrary to the output of native perl, Msys perl generates outputs with CRLFs characters. There are already places in the TAP code where CRLFs (\r\n) are automatically converted to LF (\n) on Msys, but we missed a couple of places when running commands and using their output for comparison, that would lead to failures. This problem has been found thanks to the test added in 5adb067 using TestLib::command_checks_all(), but after a closer look more code paths were missing a filter. This is backpatched all the way down to prevent any surprises if a new test is introduced in stable branches.
