From db102c67efe9cfd4367a9110c8f97ceff5afcbe3 Mon Sep 17 00:00:00 2001 From: Mark Ulrich Date: Wed, 6 Feb 2019 08:36:51 -0600 Subject: libalpm: prevent 301 redirect loop from hanging the process If a mirror responds with a 301 redirect to itself, it will create an infinite redirect loop. This will cause pacman to hang, unresponsive to even a SIGINT. The result is pacman being unable to sync or download any package from a particular repo if its current mirror is stuck in a redirect loop. Setting libcurl's MAXREDIRS option effectively prevents a redirect loop from hanging the process.
