d51e25888d Resolved ember-simple-auth deprecations
no issue

- many "The automatic session initialization is deprecated" were shown in test output due to an old method of initializing the session service
- switched to explicit session setup in the application route's `beforeModel` hook

9c3ddf4b2b Added additional error reporting and context to Sentry
refs https://github.com/TryGhost/Team/issues/1121

- adds error reporting for `notifications.showAlert()` in addition to `notifications.showAPIError()` because the former is used for some handled errors but will still show the undesired red error bar
- adds `shown_to_user` tag to all reported errors. Only errors that result in the red error bar will be reported with the tag as `true`, there may still be cases where we display errors outside of the red error bar but those wouldn't make it to Sentry either, we'll need a full audit of Admin source to find those situations and handle the reporting manually
- adds `ghost` context to errors that are shown in the red bar
  - `ghost_error_code` - code returned from the API or passed manually through the `notifications.showAPIError()` options argument. Will be filled in once the error message has been audited+approved
  - `displayed_message` - the full error message displayed to the user. Admin combines multiple attributes from the error details so it's useful to see what we actually show
  - `full_error` - the actual API error response or a client-side generated error object
  - `source` - whether the red bar came from `.showAlert()` or `.showAPIError()`, useful for tracking down where errors originated

b63a396423 Added handling for forceUpgrade state (#2116)
no issue

- Lapsed trials and subscriptions will set the site's hosting config to `forceUpgrade` in which case a Ghost(Pro) site does not have a valid subscription or trial
- In this state we need to redirect all routes for all staff users to `/#/pro` to ensure the subscription can be put back into an active state
- This commit tackles
    - Route update on startup on the application route level
    - Catching and redirecting all transition (utils routes)
    - Fetching the owner user to pass this information to the Ghost(Pro) app for better communication to non-owner staff users
    - Allowing non-owner users in the force upgrade state to transition to the `/#/pro` route

d878466215 Added grammarly tag to all Sentry exceptions
no issue

- Grammarly is a suspect in some reported editor errors but it's usage hasn't been available inside of Sentry to know for sure
- when the grammarly extension is present it adds a `data-gr-ext-installed` data attribute to the `body` element, we now use that to add a `grammarly: true/false` tag to error reports so we can more easily track down the cause of editor bugs

06e63d371c 🎨 Added ability to upload a feature image by drag and dropping an image file
refs https://github.com/TryGhost/Team/issues/884

Drop-to-upload functionality was lost in the first version of the new feature image uploader inside the main editor area, this adds it back in.

- fixed dropzone flickering issue by switching the event listeners to the capture rather than bubble phase so we can indicate a drag is occurring on the body without each individual drag/drop handler needing to know about it
- moved the event handler init/cleanup to the `ui` service
- moved the event handler init call to the application service as it no longer requires auth to have occurred for access to the labs flag setting
- removed the `featureImgDragDrop` labs flag

876c2b6cdd Added first pass at feature image drag+drop uploading
refs https://github.com/TryGhost/Team/issues/884

- added dropzone and drop handling to feature image component

c646e78fff Made session.user a synchronous property rather than a promise
no issue

Having `session.user` return a promise made dealing with it in components difficult because you always had to remember it returned a promise rather than a model and had to handle the async behaviour. It also meant that you couldn't use any current user properties directly inside getters which made refactors to Glimmer/Octane idioms harder to reason about.

`session.user` was a cached computed property so it really made no sense for it to be a promise - it was loaded on first access and then always returned instantly but with a fulfilled promise rather than the  underlying model.

Refactoring to a synchronous property that is loaded as part of the authentication flows (we load the current user to check that we're logged in - we may as well make use of that!) means one less thing to be aware of/remember and provides a nicer migration process to Glimmer components. As part of the refactor, the auth flows and pre-load of required data across other services was also simplified to make it easier to find and follow.

- refactored app setup and `session.user`
  - added `session.populateUser()` that fetches a user model from the current user endpoint and sets it on `session.user`
  - removed knowledge of app setup from the `cookie` authenticator and moved it into = `session.postAuthPreparation()`, this means we have the same post-authentication setup no matter which authenticator is used so we have more consistent behaviour in tests which don't use the `cookie` authenticator
  - switched `session` service to native class syntax to get the expected `super()` behaviour
  - updated `handleAuthentication()` so it populate's `session.user` and performs post-auth setup before transitioning (handles sign-in after app load)
  - updated `application` route to remove duplicated knowledge of app preload behaviour that now lives in `session.postAuthPreparation()` (handles already-authed app load)
  - removed out-of-date attempt at pre-loading data from setup controller as that's now handled automatically via `session.handleAuthentication`
- updated app code to not treat `session.user` as a promise
  - predominant usage was router `beforeModel` hooks that transitioned users without valid permissions, this sets us up for an easier removal of the `current-user-settings` mixin in the future

5b2194d5e8 Added Sentry error tracking for unhandled exceptions and API errors
refs https://github.com/TryGhost/Team/issues/723

- if the `/site/` API returns a `sentry_dsn` then we configure Sentry for error reporting as soon as we've loaded the initial unauthenticated data
- once we're authenticated and we have the full Ghost version available, override the Sentry event processor to use the full release
- updated `notifications.showAlert()` which is our fallback for API errors that shows the red banner at the top - these are the errors we're most interested in getting visibility for and reducing

cf7a763199 Removed usage of deprecated EmberSimpleAuth mixins (#1910)
refs https://github.com/TryGhost/Admin/pull/1901

Ember has deprecated mixins in preparation for 4.0 and `ember-simple-auth` has now done the same in 3.1.0.

- removed all imports of Ember Simple Auth mixins
- moved authenticated and invalidated handling from application route to session service
- moved server-notification loading from application route to session service
- updated `AuthenticatedRoute` to use the session service directly rather than authenticated route mixin
- added `UnauthenticatedRoute` that incorporates the behaviour from our overridden `UnauthenticatedRouteMixin` and switches to using the session service directly

- adds a "What's new" menu item next to the user popup menu
- adds an indicator to the user menu button and what's new menu item if there are unseen changelog entries
- closing the changelog modal will update the "last seen date", clearing both indicators

457a8e2955 🎨 Added auto-login to private site when viewing site preview in admin (#1286)
closes https://github.com/TryGhost/Ghost/issues/10995

- when first loading the site preview, if private mode is enabled submit the login form in the background to get the cookie before loading the iframe
- refactors post-authentication preloading to ensure it occurs before post-authentication route hooks are called
- adds `showSuccess` attribute to `<GhTaskButton>` so that when set to `false` it can stay in the running state after "success" to avoid state change flashes whilst waiting for a transition

  - updates the title each time the router service emits a route changed event
  - `ui.updateDocumentTitle()` can now be called directly from components rather than the confusing `this.send('updateDocumentTitle')` bubbling behaviour
- refactored the `titleToken` implementation to use the now-formalised `RouteInfo`'s `metadata` field (https://github.com/emberjs/rfcs/blob/master/text/0398-RouteInfo-Metadata.md#appendix-a)

352c4af1d7 Refactored usage of .get('property') with es5 getters
no issue
- ran [es5-getter-ember-codemod](https://github.com/rondale-sc/es5-getter-ember-codemod)
- [es5 getters RFC](https://github.com/emberjs/rfcs/blob/master/text/0281-es5-getters.md)
- updates the majority of `object.get('property')` with `object.property` with exceptions:
  - `.get('nested.property')` - it's not possible to determine if this is relying on "safe" path chaining for when `nested` doesn't exist
  - `.get('config.x')` and `.get('settings.x')` - both our `config` and `settings` services are proxy objects which do not support es5 getters
- this PR is not exhaustive, there are still a number of places where `.get('service.foo')` and similar could be replaced but it gets us a long way there in a quick and automated fashion

3e5a62309f Use Admin API v2 with session auth (#1046)
refs #9865
- removed all `oauth2` and token-based ESA auth
- added new `cookie` authenticator which handles session creation
- updated the session store to extend from the `ephemeral` in-memory store and to restore by fetching the currently logged in user and using the success/failure state to indicate authentication state
  - ESA automatically calls this `.restore()` method on app boot
  - the `session` service caches the current-user query so there's no unnecessary requests being made for the "logged in" state
- removed the now-unnecessary token refresh and logout routines from the `application` route
- removed the now-unnecessary token refresh routines from the `ajax` service
- removed `access_token` query param from iframe file downloaders
- changed Ember Data adapters and `ghost-paths` to use the `/ghost/api/v2/admin/` namespace

ae759d39ea Fixed multiple 401s caused by token revocation requests
no issue
- disabled Ember Simple Auth's default token revocation
    - we trigger session invalidation on a 401 which means our token isn't valid so the revoke requests will also fail
- renamed application route's `invalidateSession` to `logout` in order to distinguish it from any ESA methods
    - added the token revocation requests to this action, we can be fairly sure at this point that the current tokens will be valid so the requests will succeed
- added check to `ajax.handleResponse` so that we don't invalidate the session for requests to external services
- removed pointless assertion from the ajax integration test

refs https://github.com/TryGhost/Ghost/issues/5071

Upgrade messages are now shown on the About screen rather than as alerts. Notifications that are marked as `top` or `custom` are still shown as alerts to allow for certain upgrade messages to be given more visibility.

  - add a `message` property that contains an upgrade notification if any exists
  - add a `handleUpgradeNotification` method that accepts a Notification model instance and extracts the `notification.message` property into a html safe string for use in templates
- when loading server notifications during app boot, pass notifications that aren't marked as `top` or `custom` to the new `handleUpgradeNotification` method

0853b57244 🐛 prevent session sync issues with multiple tabs/refreshes (#772)
refs https://github.com/TryGhost/Ghost/issues/8616

- only refresh tokens on boot if we last refreshed more than 24hrs ago - this should prevent rapidly changing access/refresh tokens when opening new admin tabs or refreshing whilst other tabs are open
- fix token refresh test which was testing it's own behaviour instead of the applications 🙈

This may not be the full solution to the session issues but it closes one potential culprit and should at least reduce token churn which can only help track down the real cause.

cb59388c5b 💄🐷 sort-imports eslint rule (#712)
no issue

- adds `eslint-plugin-sort-imports-es6-autofix` dependency
  - implements ESLint's base `sort-imports` rule but has a distinction in that `import {foo} from 'bar';` is considered `multiple` rather than `single`
  - fixes ESLint's autofix behaviour so `eslint --fix` will actually fix the sort order
- updates all unordered import rules by using `eslint --fix`

With the increased number of `import` statements since Ember+ecosystem started moving towards es6 modules I've found it frustrating at times trying to search through randomly ordered import statements. Recently I've been sorting imports manually when I've added new code or touched old code so I thought I'd add an ESLint rule to codify it.

c3b49b45cf 🎨 synchronous settings service
no issue
- adds `settings` service that acts as a proxy to the singular settings model with methods to fetch and reload, also prevents accidentally loading only some settings types which has caused problems in the past
- updates app boot, signin, and signup processes to fetch settings ensuring that any part of the app can grab settings synchronously if needed
- removes `timeZone` service, it's no longer needed as we can grab `settings.activeTimezone` directly
- replaces all store queries for the settings model with appropriate `settings` methods
- refactors `apps/*` routes/controllers, they had become a little convoluted with the way they were dealing with settings and the new service helped to clean that up

6c317054c1 Fetch config from endpoint rather than meta tags (#368)
refs TryGhost/Ghost#7628 (issue), refs TryGhost/Ghost#7631 (required)

- update `config` service to fetch from public configuration endpoint
- add `beforeModel` to `application` route to fetch config and pause further processing until the request is complete
- remove `<meta name="env-*">` tags from generated `default.hbs` and internal testing `index.html`
- add mirage config to simulate configuration endpoint and helper to simulate enabled oauth config
- update `ghost-oauth2` torii provider to use auth server URL from server-provided config
