From 850d2fec53ee188bab9e458f77906041ac7f1904 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Mon, 22 Feb 2016 17:44:21 -0500 Subject: convert manual allocations to argv_array There are many manual argv allocations that predate the argv_array API. Switching to that API brings a few advantages: 1. We no longer have to manually compute the correct final array size (so it's one less thing we can screw up). 2. In many cases we had to make a separate pass to count, then allocate, then fill in the array. Now we can do it in one pass, making the code shorter and easier to follow. 3. argv_array handles memory ownership for us, making it more obvious when things should be free()d and and when not. Most of these cases are pretty straightforward. In some, we switch from "run_command_v" to "run_command" which lets us directly use the argv_array embedded in "struct child_process".

It automatically checks the array-size multiplication for overflow. 2. It always uses sizeof(*array) for the element-size, so that it can never go out of sync with the declared type of the array.
