Previously we would need to launch unicorn separately this achieves
the same goal by making 2 modifications:
1. If -u is supplied ember-cli binary will launch and monitor ember cli and unicorn
2. We suppress 200 requests to keep console clean (we may consider moving to development rails logs)
Also cleans out output a bit by supplying silent flags to yarn.
The auto restart logic was sending a USR2 to the parent process without checking what the parent process actually was. In some situations, it might not be the `bin/unicorn` supervisor.
This commit switches to use a global variable for the supervisor PID. This will be much less prone to unexpected behavior.
Using `bundle exec` will slow down server startup by at least 0.5s. `bin/unicorn` has built-in handling of bundler dependencies, so it is better to launch `bin/rails s` or `bin/unicorn` directly.
We were having issues in development mode where the JS code had errors due to a bad cache. When starting a server in development mode in bin/unicorn we now get the git sha of the discourse HEAD and get a git sha of all plugins, and store them in a file. If the sha has changed then we delete tmp/cache to refresh the assets cache.
Well all this does is amends a commit comment cause I was over eager and
pushed previous commit.
This is the comment I wanted....
This allows `pkill -USR2 -f 'ruby bin/unicorn'` to restart current unicorn
It is handy if you want to bind a keyboard shortcut for unicorn restarts
in dev.
By doing so you can avoid finding the terminal, hitting ctrl-c and then
hitting up, enter, heading back to browser.
It saves time.
Automate stuff, you will not regret it...
In dev mode sending USR2 to the unicorn master supervisor process will
restart unicorn.
This allows a simple script like this to restart unicorn in dev:
```
#!/usr/bin/env bash
kill -s USR2 `ps aux | grep ruby\ bin\/unicorn | grep -v grep | awk '{print $2}'`
```
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
This commit also cleans up a bunch of pointless noise each time we boot app
- narrative was loading i18n cause redefinition of consts
- discourse.rb was loaded twice as was auth
- bin/unicorn now does all the smart things and boots unicron in dev
- bin/rails s will boot unicorn with no params
- remove bin/puma which only causes confusion
