Re: [pacman-dev] [PATCHv2] libalpm: prevent 301 redirect loop from hanging the process

On 7/2/19 12:36 am, Mark Ulrich wrote:

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.
