From 43dc41e453b5a41e7d336b2b947eacedad2811d0 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Fri, 20 Feb 2015 09:52:07 +0000 Subject: [PATCH] Help debugging with MSys2 by optionally executing bash with strace MSys2's strace facility is very useful for debugging... With this patch, the bash will be executed through strace if the environment variable GIT_STRACE_COMMANDS is set, which comes in real handy when investigating issues in the test suite.
