* Upgrade xorm to v1.2.2 (#16663) Backport #16663 Fix #16683 * Upgrade xorm to v1.2.2 * Change the Engine interface to match xorm v1.2.2 * Add test to ensure that dumping of login sources remains correct (#16847) #16831 has occurred because of a missed regression. This PR adds a simple test to try to prevent this occuring again. Signed-off-by: Andrew Thornton <art27@cantab.net> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>
