The mailgun domain is used by the mailgun API to construct the URL for
the API. e.g for a domain of "mg.example.com" the URL for the API
messages would look like:
https://api.mailgun.net/v3/mg.example.com/messages
One weird thing about the mailgun API is that if the path does not map
to an API endpoint, then instead of a 404, we get a 200, with a body of
"Mailgun Magnificent API".
The `mailgun-js` library which we use, expects a JSON response, and will
return a body of undefined if it does not get one.
This all resulted in us trying to read the property `id` of an undefined
`body` variable. The fix here is to reject the containing Promise, if
there is no body. So that the default error handling will kick in.

- Bumping version as this is now the latest stable API.
- The change might cause this particular side effect (acceptable for major version): if a member requests a login URL when the instance is on 3.x version and site owner upgrades do 4.x before member authenticates through login link, the login will fail and the member will have to request a new login URL.

- if an accent colour is set in site settings, output a `--accent-color` CSS variable in a `<style>` tag through `{{ghost_head}}`

In order to loop over all posts, we currently need to pass a visibility="all" flag to a foreach as default for all items in current `visibility` helper is set to `public`. For a post, this behaviour is unintuitive, and inconsistent with the API. Instead, the default visibility should be "all" for the posts. The update allows themes to get all posts directly without passing in visibility -
```
{{#get "posts"}}
{{#foreach posts}}
//Loops over all posts, not just `public`
{{/foreach}}
{{/get}}
```

- The code in serializePostModel was broken and always defaulted to 'v3'! It refered to non-existent `model.get('api_version')` there's no such field in posts model! Changed the implementation so that the API version is passed in as a parameter to the method instead
- The style of providing "defaults" everywhere creates a need for future maintenance when we bump the version e.g in Ghost v5. Maybe reworking these methods to require a passed version and throwing an error instead would be more maintainable long-term?

The slack setting in 1.x did not have a `username` property. When
updating from 1.x, the migration to move the slack setting from a JSON
blob to two individual settings, would assume that the setting in the
database would have a value for the `username` property. This resulted
in errors on SQLite "sqlite does not support inserting default values."
The fix here is to add defaults when reading from the database, meaning
that we will _never_ attempt to insert `undefined`

* Moved paid subscription events population migration
This migration relies on the members_stripe_customers and
members_stripe_customer_subscriptions tables having no orphaned records
in order for it to correcly generate its data.
The migration to clean up orphaned records in those tables has not been
implemented yet, moving this migration free's up the "14" slot
* Removed orphaned stripe data from SQLite3
SQLite databases do not handle removing orphaned stripe records after a
member has been deleted. Our migration to populate the paid subscription
events relies on each customer and subscription being associated with a
member.

The migrations in 3.1.0 which added email permissions did not add those

This migration ensures that the email related permissions are added to

- Theme preview was not showing the same behaviour as a real theme because nulls were being encoded and decoded incorrectly causing nulls/empty strings to be treasted as truthy values
- Swap from using split to using proper query param parsing so that the code is more robust
- this still creates empty strings and the string 'null' so added a small function to decode these back to real nulls
- moved to its own file ready to be split out - there needs to be a bigger picture plan for this
- added unit tests to cover the known issues + some potential breakages from converting the header string to a query param object

- The original commit adding this intended to add transactions, following the pattern of always forcing a transaction when we use bookshelf-relations
- (We use bookshelf-relations here because integrations have api-keys and webhooks associated wtih them and we upsert as one)
- These add and edit methods were inadvertently added to the wrong argument object/section of bookshelf (really fucking easily done, one day we will fix bookshelf so its easier to work with)
- Bottom line: these methods have never been called
- I tried moving them to the right section, but this created test failures throughout our acceptance tests:
- Error: Transaction query already complete, run with DEBUG=knex:tx for more info
- This is likely because we need to account for integrations being used as part of the auth step in the before part of tests
- In terms of yak-shaving, fixing these tests is one step too far right now. I think not having this code here at all is a better state than having it look like it works when it doesn't

Currently, if the last4 value for a customer is empty, we end up showing `null` in theme where the card details are shown. The fix updates the last4 to return a masked value of **** instead of null if it's empty, ensuring themes using the last4 values don't have a `null` value shown to the user.

The current `{{price}}` helper only works with `amount` to convert it into right value but doesn't allow any formatting with currency etc, leaving most of the work to theme. We want to be able to output well formatted prices. E.g. the API returns 5000 for 5 EUR but we want to output €5.
The updated {{price}} helper can take a plan object or plan amount currency and use them to output a well formatted price. It works with JS's built in Intl.NumberFormat behaviour to return output in different formats, also allowing theme devs to override formatting with options.
Examples:
With Plan object => `{{price plan}} → "€5"`
With Plan object and custom number format => `{{price plan numberFormat="long"}} → "€5.00"`
Output only currency symbol => `{{price currency='EUR'}} → "€"`

The initial implementation was just to get us going with the dashboard
but the requirements have changed now, rather than updating the code we
allow to pass the `limit` options so the Admin can choose how many
events to display.
- There is now one true way to start Ghost - you create a server, and then call start with an express app
- We may well expand this again to improve testing pathways in future, but it will be done with a bit more clarity about expectations
- moved logging variable outside of the try-catch block, so it doesn't need a 2nd require
- I was considering having config,logging etc shared components required in a function together, but it's less readable
- Having a try-catch for loading shared components before main boot is also confusing

- having the logging require here means that workers wanting to use the db are unable to do so without requiring logging as a side-effect
- `connection.loggingHook` does not appear to be widely used for anything outside of specific debugging scenarios when using MySQL so it should be safe to disable until a proper fix is found for workers+logging leaking file descriptors
refs https://github.com/TryGhost/Ghost/issues/12496
By requiring the models layer the shared logging util was being required as a side-effect causing the open file descriptors problem to continue. Removing logging from the models layer isn't feasible due to deep require chains spreading across the codebase, it's much quicker to remove the need for models in the analytics job.
- models layer was only needed because it's used by the session service
- updated analytics job to create it's own instance of `EmailAnalyticsService` rather than the default instance in order to pass in custom dependencies
- pass in custom `logging` object that uses `parentPort.postMessage` as a way of writing log output

- In the old boot the server wasn't started til we were ready
- In new boot, we start the server immediately and send the old started event
- Then, when we are ready to accept some traffic, we send a ready event
- At the moment, ready isn't quite sent at the right time:
- It _should_ be when we're ready to serve real traffic, not just send 503s
- This is after the URL generation has finished
- But this requires more refactoring work :(
- So for now we send when everything else is ready
- This really needs some tests
- Notify is a more familiar name e.g. systemd has the sd_notify system which this is similar to
- We're actually announcing the server started, it's not actually ready for traffic (will serve 503s)
- use theme.ready for loading themes instead of server.start and properly clean this up
- remove server.start and server.stop as they are no longer used (only server.start was used, and only for themes)
- we're moving away from the pattern of using global events like this as they are hard to reason about
- This commit removes the old boot process and any files that are no longer needed as a result
- Remove the duplicate event for triggering inactive themes to load
- Tidied up a few other bits
- moved the DB init back into the boot file so everything is colocated - want it to be EASY to reason about whats happening
- added some more debug, and made the method signatures all the same
- expanded on comments to make it clear what the intentions are here, as there's a lot more work to do
no issue
- previously for SQLite tests we were pointing to a DB file within the
content/data folder, which would be stored on the filesystem
- by pointing this file to be under `/tmp`, the file is stored in memory
and should be a lot quicker to access
- this works great for me! - 2x faster test suite for SQLite
- however, Windows doesn't have a `/tmp` folder so we need to rewrite that
part to replace with `os.tmpdir()`
- With the new boot finalised it's clearer to see where this needs to go
- Update comments to add more clarity around what's happening and why
- Cleaned up the version require, as this was prep for maybe using version via config, which won't work in MigratorConfig
- We currently have 2 boot systems in the codebase, until now the tests were still running against the old one
- Regression tests using the forceStart + subdir flag no longer work. These need reworking, but this _should_ be easier later

* Updated members_status_events table
By replacing the `status` column with a `from_status` and `to_status`
column, we are able to track the changes between multiple statuses
easier, and accumulate the data. e.g. the delta of paid members in a
given time range is the sum of the `to_status` columns set to 'paid'
minus the sum of the `from_status` columns set to 'paid' within that
time range
* Updated MEGA to handle addition of 'comped' status
With the addition of the 'comped' status, we need to ensure that MEGA
will still send emails to the correct recipients. I've opted to use an
"inverse" filter, as that is the intention of the free/paid split in
MEGA - as far as MEGA is concerned, "free" is the opposite of "paid"
* Updated customQuery for MemberStatusEvent
With the `status` column replaced with `from_status` and `to_status`
this allows us to fix and update the customQuery to correctly accumulate
the data into deltas over time, broken down by day.
* Populated members_status_events table
As the table will be used to generate deltas, we need to backfill the
data so that existing sites will be able to sum up the deltas and
calculate correct data.
The assumptions used in backfilling is that a Member's current status,
is their only status.

Previously, {{content}} helper was updated use default or custom template to show a CTA when trying to use helper without access to content.
While the change was expected to not affect any existing themes as `{{content}}` helper is not supposed to be used on member sites without `access` check, we found quite a few themes use a pattern of using `content.hbs` with `{{content}}` helper inside them as default, which causes infinite loop in how content helper works in certain cases.
Whilst this followed the pattern of the other helpers using a partial with the same name, there are 2 key differences:
- this partial template pattern is being introduced way after the inception of themes with a fairly generic name “content”
- this partial template isn’t used to render the helper all the time - just the CTA part under certain circumstances.
This change updates the template name to `content-cta.hbs` to which makes it less likely to clash, and makes more sense as to what it is.

Background:
- Ghosts existing boot process is split across multiple files, has affordances for outdated ways of running Ghost and is generally non-linear making it nigh-impossible to follow
- The web of dependencies that are loaded on boot are also impossible to unpick, which makes it really hard to decouple Ghost
- With 4.0 we want to introduce a new, linear, simpler, clearer way to boot up Ghost to unlock decoupling Ghost into much smaller pieces
This commit:
- adds a new ghost.js file which switches between boot mode with `node index` or `node index old` so that if we find bugs we can work around them this week
- Note: the old boot process will go away very soon, but ghost.js will remain as the interface between the command to start Ghost and the application code
- reworks the database migration process into a standalone utility, so that the DB is handled as one simple step of the boot process, decoupled from everything else
- is missing tests for this new db utility
- leaves a lot of work to do around loading core code, services, express apps in a sensible order, as work to fix this would start to break the old boot process
- doesn't use the new maintenance app because we aren't restarting the server here, instead we have the concept of a "core app" that starts in maintenance mode - need to think about how apps will be decoupled in the near future
