Revert "We have had errors reported due to migrations breaking and are reverting"
This reverts commit 8b46f14744.

It corrects the reason for the revert:

We rely on SafeMigrate existing cause we call it from migrations,
Zeitwerk will autoload it.

Instead of previous pattern we explicitly bypass all the hacks in
production mode.

We need to disable SafeMigrate cause it is not thread safe.

A thread safe implementation is possible but not worth the effort,
we catch the issues in dev and test.

DEV: avoid loading module in production 2020-04-09 13:54:18 +10:00

DEV: only enable SafeMigrate in development and test
SafeMigrate outputs text when we detect attempts to unsafely drop tables
and columns

It is unfortunately not thread safe

This is not needed in production as we would have already caught it by then
in our test suite.

Daniel Waterworth bca126f3f5 REFACTOR: Move the multisite middleware to the front

Robin Ward 27641f21e4 Migrate `discourse-common` from es6 -> js 2020-03-23 15:05:58 -04:00
Gerhard Schlager 8022e51179 FIX: Failed to restore backups from versions without translation overrides
Rails calls I18n.translate during initialization and by default translation overrides are used. Database migrations would fail if the system tried to migrate from an old version that didn't have the `translation_overrides` table with all its columns yet.

This makes restoring really old backups work again. Running `DISABLE_TRANSLATION_OVERRIDES=1 rake db:migrate` will allow you to upgrade such an old database as well.

Support for transpiling `.js` files (#9160)
* Remove some `.es6` from comments where it does not matter

* Use a post processor for transpilation

This will allow us to eventually use the directory structure to
transpile rather than the extension.

* FIX: Some errors and clean up in confirm-new-email

It would throw an error if the webauthn element wasn't present.
Also I changed things so that no-module is not explicitly
referenced.

* Remove `no-module`

Instead we allow a magic comment: `// discourse-skip-module` to prevent
the asset pipeline from creating a module.

* DEV: Enable babel transpilation based on directory

If it's in `app/assets/javascripts/dicourse` it will be transpiled
even without the `.es6` extension.

* REFACTOR: Remove Tilt/ES6ModuleTranspiler

FIX: Patch ActiveRecord SchemaCache for safe concurrency support
A single SchemaCache instance is maintained by the connection pool, and made available via a schema_cache method on each connection. When the SchemaCache instance is fetched from the pool, its internal connection reference is updated to equal the requesting connection. However, since there is only one instance of SchemaCache, this internal connection reference is updated everywhere, and can ultimately result in multiple threads accessing the same database connection. In Discourse, this could result in Sidekiq jobs getting 'stuck' in database connections.

This patch modifies SchemaCache so that it caches the internal connection on a per-thread basis

PERF: avoid shelling to get hostname aggressively
Previously we had many places in the app that called `hostname` to get
hostname of a server. This commit replaces the pattern in 2 ways

1. We cache the result in `Discourse.os_hostname` so it is only ever called once

2. We prefer to use Socket.gethostname which avoids making a shell command

This improves performance as we are not spawning hostname processes throughout
the app lifetime

Daniel Waterworth 55a1394342 DEV: pluck_first
Doing .pluck(:column).first is a very common pattern in Discourse and in
most cases, a limit cause isn't being added. Instead of adding a limit
clause to all these callsites, this commit adds two new methods to
ActiveRecord::Relation:

pluck_first, equivalent to limit(1).pluck(*columns).first

and pluck_first! which, like other finder methods, raises an exception
when no record is found

Redis gem is manipulating Redis config https://github.com/redis/redis-rb/blob/master/lib/redis/client.rb#L95
therefore we cannot pass the frozen config object.

Pass of the copy of the object is protecting original config

Ruby patterns to require files.

FEATURE: SKIP_DB_AND_REDIS env var (#7756)
Sometimes we would like to create a base image without any DB access, this
assists in creating custom base images with custom plugins that already
includes `public/assets`

Following this change set you can run:

```
SPROCKETS_CONCURRENT=1 DONT_PRECOMPILE_CSS=1 SKIP_DB_AND_REDIS=1 RAILS_ENV=production bin/rake assets:precompile
```

Then it is straight forward to create a base image without needing a DB or
Redis.
