Overview

USSR

Ultimate Score Server for RealistikOsu (well not just us but it makes the acronym work.) Also I wonder how long this name will last.

What is this?

NOTE: ALL OF THIS APPLIES TO THE PLANNED FINISHED PRODUCT. THIS IS NOT YET FINISHED, SO NOT EVERYTHING MENTIONED IS PRESENT

The primary objective of the USSR is to serve as an almost drag and drop replacement for Ripple's LETS as a score server. This means for existing server owners:

Usage of the usual Ripple database schema.
Full usage of the Ripple Redis API (pubsubs, keys etc).
Full support of the Ripple JSON API.

All of this while also MASSIVELY improving upon LETS in the following areas:

Massive performance gains
Significantly more efficient with the database and other resources
Modern asynchronous Python architecture

Comments

Recalculation based pubsubs

Expands the recalculation capabilities, offering a redis api for access.

Adds the pubsubs: ussr:recalculate_user - Performs a PP and accuracy recalculation. ussr:recalculate_user_full - Recalculates the users pp, acc, max combo, total score and ranked score.

Refactor osu!direct
With direct being one of the first systems being implemented, it has fallen behind the standard for the score server. A new refactor would ideally consider:

Being split into more reusable functions and/or classes.

Have bancho mirroring be optional (within the config)

[Optional] Support account pools with a sort of load balancer between each.

Raw mirror support (302)

Stop pp cap from restricting on non-submitted scores

Originally intentional but turned out to be victim of abuse cases. In the future would like to make it submit a webhook, but for now removing it is the best action.

Remove ScoreV2 as a rankable mod.

Since the rewrite (or even earlier), score V2 has been allowed on the leaderboards. This is a major oversight due to its radical changes to the scoring system, which are incompatible with all other mods. This causes major discrepancies within score leaderboards.

Re-enable convert performance points
The newest rosu-pp version (0.6.0) introduces convert support. This means that convert pp can be reasonably re-added into USSR.

Note:

Requires testing on whether rosu-pp accepts integer mode enums.

Rewrite Leaderboards

Current leaderboards system is rather unflexible and honestly a giant mess. It may work phenomenally in prod (as experienced) but the code aspect could see some nice improvement. I believe a system similar to Acachesuki would be perfect.

restrict_user banning users instead

This is an issue observed on the RealistikOsu deployment of USSR and can be seen within PP cap bans. The intended behaviour is for the user to be restricted (privilege value of 2), granting them limited access to the server. Instead, they are completely banned by (likely) USSR.

Inconsistent total PP calculations

Users are ranomly experiencing random large quantities of PP being added or substracted from their total on score submit (ranging between 50 and 300). This occurs on total pp recalc.

Need more info.

A collection of minor (mainly annotation based) fixes

These changes do not affect program logic (outside of a single binary change), but rather focus on fixing most of the typing issues within the project and covering some possibilities where unexpected values may result in difficult to debug scenarios.

Make USSR Stateless

This PR aims to make USSR completely stateless, utilising Redis for its caching. This is part of our goal to containerise the RealistikOsu software stack.
