From adc95f436b55dde320e9be9e38e7f4b48df4cdc5 Mon Sep 17 00:00:00 2001 From: Allan McRae Date: Tue, 9 May 2017 11:35:06 +1000 Subject: Do not continuously try to open an invalid database If you manage to download a bad database (e.g. an html file when behind a proxy or with a badly configured webserver), pacman makes sure you know about it. Here is some example output: error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format error: could not open file /var/lib/pacman/sync/extra.db: Unrecognized archive format I don't know how many times that gets printed because it goes beyond my scrollback buffer. Flag a database that we can "open" and "fstat" but not read from as invalid to avoid this.
