From 2893ed3c36ff95f548df44071fa2fb3bdd27cbf5 Mon Sep 17 00:00:00 2001 From: merakor Date: Mon, 31 Aug 2020 21:19:22 +0000 Subject: cpt-lib: repository and source revamp. See log. Many additions and changes here, - added support for Mercurial sources - added support for Mercurial repositories - adapted git source changes from kiss - Changed rsync repository behaviour: A new file has been added to rsync repositories: .rsync_root This file points to the repository root. If the directory that .rsync_root points also has an '.rsync' file, this will be accepted as the root directory and the rsync operation will take place on the root. This ensures that we can have repository exchanges on a single rsync call, while still allowing for partial repositories.
