FARSIDE_CRON allows turning on/off the scheduled instance availability
check that occurs every 5 minutes by setting the variable to 1 (on) or 0
(off). The default behavior is "on".
This introduces a simple way of compiling Farside to a somewhat portable,
standalone binary. The resulting binary isn't completely portable since it
depends on the C runtime of the host system. As a result, it's advised to use
systems with older library versions when compiling for true portability.

This removes the dependency on Redis for core app functionality. Rather
than using the key/value store provided by Redis, Farside now uses a
key/val store provided by [cubdb](https://github.com/lucaong/cubdb) for
identical functionality but without reliance on a non-Elixir service.
This solution was chosen instead of ets, because storing instance data
in memory leads to a period of broken functionality whenever the app
restarts and hasn't re-populated instance data yet. It was also chosen
instead of dets, because the documentation for dets was pretty hard to
understand at first glance.
Tests and the CI build were updated to reflect the removed dependency on
Redis.
New environment variable `FARSIDE_DATA_DIR` can be used to point to a
directory where the instance data can be stored by cubdb.

Connection values (such as redis server port and the port to run farside
on) as well as the services json file to use can now be set via
environment variables:
FARSIDE_PORT sets the port for Farside to run on
FARSIDE_REDIS_PORT sets the redis server port for Farside to use
FARSIDE_SERVICES_JSON sets the services json file for Farside to use
This partially addresses the move towards de-listing Cloudflare
instances by default by allowing different services json files to be
used with different redis servers.
See #43
The demo table doesn't include all available services that are supported by
Farside, and likely shouldn't anyways since it already clutters up the readme a
bit. The existing demos should give a good enough idea of how Farside works and
how to use it.
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.
