- Same reason as in refed commit, ltdc:
- Traditionally all of Ghost's public-facing text was written in British English
- We're changing that to US English because that's more common
- US English should also be used in code e.g. properties are called color not colour
- This stops the mounting of the admin and frontend from being buried deep in express initialisation
- Instead it's explicit, which makes two things almost possible:
1. we can potentially boot the frontend or backend independently
2. we can pass services and settings loaded during boot into the frontend
- This needs more work, but we can start to group all the frontend code together
- Meanwhile we also need to rip apart the routing and url services to decouple the frontend from the backend fully
- BABY STEPS!
- The router bootstrap is no longer allowed to fetch it's own settings, but rather is passed them
- This moves the call to the site routes.js file, which isn't much better but it's a start
- The goal is to always pass these in from the boot process, or from the bridge reloader
- this was skipped on boot, but then called in the test utilities, but only on restart 🙈
- this means that yarn test:acceptance (i.e. running all tests) works, but if you try to run just test/api-acceptance/themes_spec.js it would fail because that uses a fresh boot not a restart/reload
- I've changed this as keeping the test using the real boot, rather than the made-up acceptance-utils tasks as much as possible is way better
- At the moment the bootstrap.start method asks the settings service for its settings
- This couples the routing and settings services together - when maybe we want to use a different method to generate settings
- By passing the settings to the routing service at the right time, we open up possibilities for refactoring
- At the moment the bootstrap.start method asks the settings service for its settings
- This couples the routing and settings services together - when maybe we want to use a different method to generate settings
- By passing the settings to the routing service at the right time, we open up possibilities for refactoring
- config now exposes a few helpful methods: getSubdir, getSiteUrl, and getAdminUrl
- we can use these directly, instead of needing url-utils
- switching this inside of the boot process allows us to move the loading of url-utils into `initCore` which happens after the server has started and the database is ready
- this moves 100ms of loading time to later in the process
- also simplifies the initial loading
- Cleaned up some of the comments
- Added proper method signatures where appropriate
- Split initDynamicRouting out from initServices, to make that clearer to read

- As per comment on the top of boot.js:
// IMPORTANT: The only global requires here should be overrides + debug so we can monitor timings with DEBUG=ghost:boot* node ghost
- Referenced change broke the rule above and would have caused all sorts of boot problems.
refs https://github.com/TryGhost/Team/issues/754
- This is a minor cleanup. There should be no logic in the boot.js file other than calling services to "initialize themselves"
no issue
The only pieces of Ghost-Ignition used in Ghost were debug and
logging. Both of these modules have been superceded by the Framework
monorepo, and all usages of Ignition have now been removed, replaced
with @tryghost/debug and @tryghost/logging.

- Webhook listener was still kicking in when the limit for "customIntegrations" was in place. This is due to parallel initialization that was done previously and sometimes limit service initialized before webhooks but sometimes it didn't!
- Moving it to be initialized before any othe service ensures the race conditon doesnt happen anymore
- Note: added a forced error to show that this was previously happening at the wrong time
- i18n is required by ghost-server to log server start messages, and so gets initialised as part of the ghost-server load
- moving this into the right place means we can see how long it takes in the debug logs
- previously the debug log lines for i18n showed 0/1ms, which is not correct as this contains a sync file load operation!
- we should consider if we want to have i18n be a requirement for ghost server, or if we want static messages
- We only require a single value from urlUtils, the url for the site
- Move that logic back to the boot file makes it much more explict
- Will help if we want to refactor how urlUtils works, or when we want to move ghost-server out of core
refs 829e8ed010
- i18n is used everywhere but only requires shared or external packages, therefore it's a good candidate for living in shared
- this reduces invalid requires across frontend and server, and lets us use it everywhere until we come up with a better option
- Having these as destructured from the same package is hindering refactoring now
- Events should really only ever be used server-side
- i18n should be a shared module for now so it can be used everywhere until we figure out something better
- Having them seperate also allows us to lint them properly

- continuing the work of splitting up the theme service into logical components
Themes Service
- The serverside theme service now serves just the API and boot
- It loads the theme and passes it to the theme-engine via the bridge
This achieves the bare minimum goal of removing all the cross requires between server and frontend around themes
There is still a lot more to do to achieve an ideal architecture here as laid out in ae86254972
- Modules in /shared are supposed to be standalone modules that can be required by the server or frontend
- As the server shouldn't require the frontend, and vice versa, shared modules should require neither
- Otherwise it just becomes a crutch for allowing cross-depenencies, and will create circular dependencies
The Bridge
- The bridge file is not meant to be a crutch sat allowing cross-dependencies, but rather a new component that manages the flow of data
- That data flows from the server/boot process TO the frontend, and should not flow in the other direction
- The management of that flow of data is necessarily hacky at the moment, but over time the architecture here should get clearer and better
- Still, for the time being it will need to handle requiring across components until that architecture matures
- Therefore, it should live in core root, not in core/shared
refs: bf0823c9a2
- Added a new bridge class that lives in shared. This should eventually be responsible for all cross-communication between the frontend and the server
- Having all the gnarly shared bits in one place should help us refactor more easily
- For now it also reduces requires between the core/server and core/frontend folders that are meant to be separate
- All calls to getApiVersion have also been renamed to getFrontendApiVersion, as this is different to the "default" API version
- Slowly getting to the point where frontend/services/themes can be moved to server/services/themes :)

- We have default API versions littered all over the codebase. When we updated to Ghost v4 we realised just how many and how much of a pain in the ass this is to manage.
- This creates a config value we can use. It's in overrides for the time being because we usually default to that until there is a usecase for it being overridable. If there is one, cool, change it!
- The main motivation for adding this now and only using it in boot and urlUtils is as part of work to decouple the theme service into logical compontents, because the engines system inside of themes has its own default, and this is one cause of tight coupling
- Expectation is that we'll slowly roll out use of the new default, hopefully without requiring config in any additional places (e.g. passing the version in from the boot file)
refs: https://github.com/TryGhost/Team/issues/558
- we can't use our logging lib to log a config error, because logging requires config to work
- we have to use console, as there's nothing else available at this point
- we can't even use notify to tell CLI a bad thing happened here, because that also requires config and logging
- there is no precedent or ref material for the code 999
- it's just meant to be a clearly different code to -1/1/2/3 we've used elsewhere
- it signifies that things went so wrong we weren't even able to handle the error gracefully with logging
refs: https://github.com/TryGhost/Team/issues/510
- added and wired up the new limit service, which is a lazy-loaded service
- this handles the case that there are host limits set in config, and wraps all the logic needed for detecting exceeded limits & throwing limit errors
- expects limits to be set in config under `host_settings.limits`
- supported limits are managed in the limit service, outside of core

- The bump does not effect scheduled post as URL with authentication token is generated during runtime for DefaultScheduler.
- This needs to be checked for SchedulerAdapter implementations which use persistant storage
- Continuing cleanup and clarification of the boot process
- By locating requires and inits more closely together its easier to see what happens where and to get timings
- Improved consistency of the debug begin/end statements
- Added "Step" comments to the main process
- Inlined the mountGhost function, for readability and consistency with the other steps
- 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
- This is simplest and most readable IMO
refs dd715b33dc
- this is the last event that is used to trigger part of the standard boot process
- events make the code harder to read/reason about
- the urlservice is one of the most core and critical components in Ghost, possibly the biggest consumer of time and memory
- we want to have the work it is doing front and center so that we can improve it
refs b1a98b0b67
- note: I already replaced server.start with themes.ready in the above commit
- events make the code harder to read/reason about
- long term it would be nice to have a concept of hooks for services, but for now explicit is clearer
- 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)
- 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
- 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
- Note those tests work fine if they were the first tests run, it is only the case of trying to restart the server with a subdirectory after starting without that doesn't work
- Currently the new boot process breaks the loading of inactive themes because the theme loader event isn't wired until after the server.start event is fired
- This is a WIP fix, there needs to be some bigger refactoring of the boot process once the old process is gone
refs 0b79abf5b2
- in the referenced commit, we refactored the boot code to simplify it
- one of the required files was not updated with the change, so the path
was wrong
- this wouldn't have been easily visible from local testing because it's
based upon a config flag that isn't on by default
- this commit updates the path to the file
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
