From 0e90673957f12adc1a84b13d3dfff02151e4a7a8 Mon Sep 17 00:00:00 2001 From: René Scharfe Date: Sun, 30 Oct 2022 12:51:14 +0100 Subject: use child_process members "args" and "env" directly MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Build argument list and environment of child processes by using struct child_process and populating its members "args" and "env" directly instead of maintaining separate strvecs and letting run_command_v_opt() and friends populate these members. This is simpler, shorter and slightly more efficient.
