This change expands the matcher added in 02bebb7e91 to include plugin `settings.yml` files as requiring a server restart when they change.
The `Listen.to(only: ...)` filter only matches against filenames (as opposed to full paths) so we can't add a matcher against `plugins/.*/config/settings.yml` to make it explicit.
site_settings.yml is read when the server starts, but isn't re-read if it changes. (Eg, adding a new setting, or changing the configuration of an existing setting.)
This change includes site_settings.yml as a file that requires a server restart when it changes. This behaviour obeys the AUTO_RESTART environment variable.
The Listen gem watches recursively, which has a cost per-file on Linux (via rb-inotify). This commit skips a bunch of unnecessary directories to reduce the startup cost.
Since ad6c028484
in the zeitwork repo which was introduced to discourse/discourse in PR #20253,
the `autoloads` attribute on the loader has been marked `internal`, which means
that it errors if we try to access it directly.
Instead we should access it via the "mangled" version so it is clear
we're accessing an internal property, which is `__autoloads`.
Without this, any time a ruby file is saved the
000-development_reload_warnings.rb initializer will error.
Also:
* Remove an unused method (#fill_email)
* Replace a method that was used just once (#generate_username) with `SecureRandom.alphanumeric`
* Remove an obsolete dev puma `tmp/restart` file logic
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.
This commit adds a listener on (almost) all `.rb` files in the repository. When a change occurs, it checks whether Zeitwerk is responsible for autoloading it. If not, a warning will be printed to the console and the server will be automatically restarted. Optionally, you can pass the `AUTO_RESTART=0` environment variable to prevent auto-restart.
