refs #7489 - new database versioning scheme which is based upon the Ghost version, and so easier to reason about - massive refactor of all the version related code Summary of changes: * ✨ new error: DatabaseNotSeeded * 🎨 change versioning module - versioning is based on Ghost Version * 🎨 change bootUp file - add big picture description - version error get's trigger from versioning module * 🎨 default setting for database version is null - very important change: this is caused by the big picture - see bootUp description - the database version get's set by the seed script later - db version is by default null - 1. population happens (we ensure that this has finished, by checking if each table exists) - 2. seeds happening (we ensure that seeds happend if database version is set to X.X) * 🎨 temporary change for population logic - set database version after population happens - ensure population of default settings happend before - both: get's removed in next iteration * 🎨 adapt tests && mark TODO's * 🎨 err instance checking

* @TODO:

* - 2. call is check if db is seeded
|
|

|
|
* These are the calls Ghost will make to find out if the db is in OK state!
|
|
* These check's will have nothing to do with the migration module!
|
|
* Ghost will not touch the migration module at all.
|
|
*
|
|
* Example code:
|
|
* models.Settings.findOne({key: 'databasePopulated'})
|
|
* If not, throw error and tell user what to do (ghost db-init)!
|
|
*
|
|
* versioning.getDatabaseVersion() - not sure about that yet.
|
|
* This will read the database version of the settings table!
|
|
* If not, throw error and tell user what to do (ghost db-seed)!

|
|
