Although the current list of queries is only 2 elements ("time" and
"weather"), this allows searches for Whoogle and Searx to be slightly
more random, and potentially avoid any issues with their parent engine
rate limiting them.
* Create nightly update workflow for instances
A nightly GitHub Actions CI workflow has been added to fetch new
instances of supported services within Farside.
Currently only Searx is supported, but obviously others could be added
if there are similarly easy ways to fetch and filter instances
programmatically.
services.json has also been updated with the initial results of the
workflow script.
* Set headers for every HTTPoison request
This serves as a workaround for bot blocking via filtron.
* Expand filtering of searx instances
New filter enforces:
- No Cloudflare
- Good TLS config
- Good HTTP header config
- Vanilla instances or forks
- Instances with 100% search success
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).
Introduces a new db key "<service>-previous" to track which instance was
last selected for a particular service. This allows for filtering the
list of available instances to exclude the instance that was last
picked, to ensure a (slightly) more even distribution of traffic.
There's still the possiblity of the following scenario, however:
:service instances > 2
/:service request #1 -> instance #1
/:service request #2 -> instance #2
/:service request #3 -> instance #1
/:service request #4 -> instance #2
where there are many ignored instances for a particular service. One
possible solution would be to implement the "<service>-previous" value
to be a list, rather than a single value, and push to that list until
only one element is left in the original "instance" array after
filtering, and then delete the "<service>-previous" key.
This introduces a number of new changes:
- Services are now inserted into redis with a prefix prepended to the
key name. This allows for easier filtering to get only live instances.
- The home page now uses an eex template for displaying all live
instances for every service, determined by the last update
- A "last_updated" field was added
- farside.ex was added to contain all functionality related to querying
for instances (WIP)
- Other improvements
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.
Not sure if this is the Elixir-y way to do this, but seems more logical
than hardcoding values such as redis connection.
Also went through and improved how string formatting was performed
throughout the app. Rather than "combining" <> "strings" this way, I'm
now just doing "#${variable}#{formatting}", which looks a lot cleaner.
