`Settings.populateDefaults()` is run before migrations during Ghost's startup. This can cause problems when new settings table columns are added (and populated in `default-settings.json`) because `populateDefaults()` was using the model layer which assumes that those columns are available, resulting in `ER_BAD_FIELD_ERROR: Unknown column` type errors.
- query the database for the available `settings` table columns
- switch to using raw knex queries without Bookshelf for insertions so that we're in control of the columns that are added
- use `_.pick` to skip any properties in `default-settings.json` that do not match to an available column - those columns will be added and populated by later migrations
- moving away from using the model to insert settings has the side-effect of not emitting `settings.added/edited` and `settings.x.added/edited` events, this should be fine because `populateDefaults()` is called before anything else is set up and listening
- added a call to `populateDefaults()` in our knex-migrator "before migration" hook so that we have consistent db state across both startup initialised migrations and manually triggered knex migrations
- All var declarations are now const or let as per ES6
- All comma-separated lists / chained declarations are now one declaration per line
- This is for clarity/readability but also made running the var-to-const/let switch smoother
- ESLint rules updated to match
How this was done:
- npm install -g jscodeshift
- git clone https://github.com/cpojer/js-codemod.git
- git clone git@github.com:TryGhost/Ghost.git shallow-ghost
- cd shallow-ghost
- jscodeshift -t ../js-codemod/transforms/unchain-variables.js . -v=2
- jscodeshift -t ../js-codemod/transforms/no-vars.js . -v=2
- yarn
- yarn test
- yarn lint / fix various lint errors (almost all indent) by opening files and saving in vscode
- grunt test-regression
- sorted!

- required a reordering of Ghost's bootstrap file, because:
- we have to ensure that no database queries are executed within Ghost during the migrations
- make 3 sections: check if db needs initialisation, bootstrap Ghost with minimal components (db/models, express apps, load settings+theme)
- create a new `migrator` utility, which tells you which state your db is in and offers an API to execute knex-migrator based on this state
- ensure we still detect an incompatible db: you connect your 2.0 blog with a 0.11 database
- enable maintenance mode if migrations are missing
- if the migration have failed, knex-migrator roll auto rollback
- you can automatically switch to 1.0 again
- added socket communication for the CLI
no issue
- adapt major changes of knex-migrator v3
- adapt migration scripts, simplify and add `down` (rollback) hook if possible
- clear Ghost cache after init hook (because of `knex-migrator migrate --init`)
- ensure db migrations work with the CLI
- updated troubleshooting guide (https://docs.ghost.org/v1/docs/troubleshooting#section-task-execute-is-not-a-function)
**For development only: Please ensure you run `npm i -g knex-migrator@latest` to update your global installation to v3. We always prefer the local installation, but v3 has modified and added binaries.**
refs #7489
- as we are now using a different migration approach (knex-migrator), we don't need to remember the database version anymore
- it was once used to check the state of a database and based on it we decided to migrate or not
- with knex-migrator everything depends on the migration table entries and the current ghost version you are on
- on current master the leftover usage is to add the db version when exporting the database, which can be replaced by reading the ghost version
- removing this solves also an interesting migration case with knex-migrator:
- you are on 1.0
- you update to 1.1, but 1.1 has no migrations
- the db version would remain in 1.0
- because the db version was only updated when knex migrator executed a migration
refs #7489
The require path for the db backup was wrong. The before hook could not execute db backup.
Furthermore, i have replaced the logging in the backup script.
