From c9e04d905edb5487c43b03304704e8d1248f9ac0 Mon Sep 17 00:00:00 2001 From: Thomas Gummerer Date: Mon, 31 Jan 2022 13:30:47 +0000 Subject: fetch --prune: exit with error if pruning fails When pruning refs fails, we print an error to stderr, but still exit 0 from 'git fetch'. Since this is a genuine error, fetch should be exiting with some non-zero exit code. Make it so. The --prune option was introduced in f360d844de ("builtin-fetch: add --prune option", 2009-11-10). Unfortunately it's unclear from that commit whether ignoring the exit code was an oversight or intentional, but it feels like an oversight.
