Added a new seperate service for only redirecting to SearXNG instances.
Note that plain "searx" redirects will use both SearX and SearXNG
instances for those who don't have a preference between the two.
Closes#23
This adds a straightforward way of preserving Farside's redirecting
behavior in the user's browser history. That way if an instance becomes
unavailable between the 5 min scans, the user can opt to navigate back
one page and be taken to a new instance.
This is accomplished using a single line of JS, and could potentially
work as the default behavior of Farside (with the current default
behavior requiring a path prefix instead). This should be revisited down
the road when more people are using this service.
Rather than enforcing a 200 status code, the instance query is deemed a
success if the status code is <400. Various services return 200-399
status codes that don't necessarily indicate an error, but may have to
do with how the instance was configured.
The FARSIDE_NO_ROUTER variable wasn't terribly useful after refactoring
the app to include the update routine internally (rather than available
externally as an elixir script).
Now the only supported environment variable is FARSIDE_TEST, which is
still useful for tests and quick validation of functionality.
Rather than requiring a traditional crontab install, the app now
leverages quantum-core (link below) to schedule the instance update/sync
task every 5 minutes. Some updates as a result:
- The new job is scheduled at runtime in server.ex.
- The update.exs script was refactored to be compiled along with the
rest of the app as instances.ex.
- Scheduler and Server modules were added for creating and executing
the new update task
- All shell scripts were removed, as they are no longer needed
https://github.com/quantum-elixir/quantum-core
Setting the aforementioned env var skips creation of the app router,
which is useful for running update.exs when the main app is already
running (otherwise there's a port conflict).
The name of the project is being refactored from Privacy Revolver to
Farside. The reasoning behind this is:
1. A shorter name is easier to remember
2. It can stand for "FOSS alternative redirecting service" (which I know
doesn't encapsulate all letters from "farside", but it's close enough).
This commit also includes improvements to the update script for
determining how far along the script is.
