From a95fbf2aec91796d872c1d3db3c1c7d6f6243340 Mon Sep 17 00:00:00 2001 From: Veronika Kabatova Date: Wed, 14 Feb 2018 14:34:28 +0100 Subject: Implement list filtering Sometimes, multiple projects reside at the same mailing list. So far, Patchwork only allowed a single project per mailing list, which made it impossible for these projects to use Patchwork (unless they did some dirty hacks). Add a new property `subject_match` to projects and implement filtering on (list_id, subject_match) match instead of solely list_id. Instance admin can specify a regex on a per-project basis when the project is created.
