Security changes audit

Starting from version 2.5 Genesis has an audit for security changes. No REST or UI provided. A special table is created in Genesis schema with the following content (MySQL syntax):

CREATE TABLE `permission_changes` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `roleName` varchar(64) DEFAULT NULL,
  `projectName` varchar(128) DEFAULT NULL,
  `confName` varchar(128) DEFAULT NULL,
  `projectId` int(11) DEFAULT NULL,
  `confId` int(11) DEFAULT NULL,
  `changeType` int(11) NOT NULL,
  `payloadType` int(11) NOT NULL, 
  `changedItem` varchar(255) NOT NULL,
  `changedAt` datetime NOT NULL,
  `changedBy` varchar(128) NOT NULL,
  PRIMARY KEY (`id`)
)

Examples

Find all additions to a system role 'ROLE_GENESIS_ADMIN':

select changedItem, changedAt, changedBy from permission_changes where roleName = 'ROLE_GENESIS_ADMIN' and changeType = 0; 

Find all changes in predefined roles:

select roleName, changeType, changedItem, changedAt, changedBy from permission_changes where roleName is not null

Find all changes in specified project with id = 1 (without configuration):

select roleName, changeType, changedItem, changedAt, changedBy from permission_changes where roleName is not null and projectId = 1

Find only user changes in specified project with id = 1 (without configuration):

select roleName, changeType, changedItem, changedAt, changedBy from permission_changes where roleName is not null and projectId = 1 and payloadType = 0

Find all changes in specified configuration (conf. id = 1, project id = 1):

select changeType, changedItem, changedAt, changedBy from permission_changes where projectId = 1 and confId = 1
