[PATCH v2 08/12] use child_process members "args" and "env" directly

From
René Scharfe <l.s.r@web.de>
Date
Oct 30, 2022, 11:51 UTC
Message-ID
<97566ec6-ad18-a53a-ed1f-2148706fbd25@web.de>
In-Reply-To
<ea061164-b36b-485c-963f-8c13e813a47e@web.de>

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.
