From 797acc24457e34c29332d9f1be5bd19e84aab111 Mon Sep 17 00:00:00 2001 From: Matthew Barnes Date: Tue, 2 Mar 2010 15:00:01 -0500 Subject: Drop support for migrating from Evolution < 2.0. There's too much ancient, crufty code there that we can't realistically support anymore. A workaround for those poor users still on 1.x is to upgrade to some 2.x release first, then upgrade again to 3.x. An error dialog explaining this will be shown at startup. --- modules/calendar/e-task-shell-migrate.c | 495 +------------------------------- 1 file changed, 2 insertions(+), 493 deletions(-) (limited to 'modules/calendar/e-task-shell-migrate.c') diff --git a/modules/calendar/e-task-shell-migrate.c b/modules/calendar/e-task-shell-migrate.c index 3c3210b472..9fe9870c73 100644 --- a/modules/calendar/e-task-shell-migrate.c +++ b/modules/calendar/e-task-shell-migrate.c @@ -37,8 +37,6 @@ #include #include -#include "e-util/e-bconf-map.h" -#include "e-util/e-folder-map.h" #include "e-util/e-util-private.h" #include "calendar/gui/calendar-config.h" #include "calendar/gui/calendar-config-keys.h" @@ -47,396 +45,6 @@ #define WEBCAL_BASE_URI "webcal://" #define PERSONAL_RELATIVE_URI "system" -static e_gconf_map_t calendar_tasks_map[] = { - /* /Calendar/Tasks */ - { "HideCompletedTasks", "calendar/tasks/hide_completed", E_GCONF_MAP_BOOL }, - { "HideCompletedTasksUnits", "calendar/tasks/hide_completed_units", E_GCONF_MAP_STRING }, - { "HideCompletedTasksValue", "calendar/tasks/hide_completed_value", E_GCONF_MAP_INT }, - { NULL }, -};
