Ava Affine 568e6a3163 Internal event state tracking and Pub/Sub model
Internal state tracking:
This commit introduces the concept of internal events. The thought here
is that bingobot will track its current state not by variables set from
incoming discord event data but rather from a cache of internal events that
represent digested and simplified observations made and actions taken by
internal code. Currently the events that are defined include the following:

- UserActive Events:
  These events are intended to be generated when a user is noticed to have
  been sitting in a voice chat for more than 10 minutes, however they can be
  generated in response to anything that signifies that a user has been active

- Challenge Events:
  These events signify that a user has been challenged. They are intended to
  act as a primitive form of restraint from using bot features. It is intended
  that these are made only as a response to a successful vote.

- Restore Events:
  These events signify that a user has been restored to non-challenged status.
  It is intended that this only happens in response to a successful vote.

- Vote Events:
  These events serve as the primary means of consensus building, and represent the
  state of a single active ongoing or finished vote.

Currently the events are cached for 10 days and then discarded, but future work will
add an on disk document storage for old events should any functionality desire it.

This internal event cache is intended to be the authoritative source of truth for
information about user permissions, vote results, and any additional future
functionality that relies on shared state. It is accessed through a GetMatchingEvents
function that accepts both an event type and a map of optional metadata filters.
See state_test.go for examples of this functionality. In addition to the cache
search function there is also a Publisher/Subscriber setting elaborated on below.

Pub/Sub system:
This commit also introduces a Pub/Sub system for other internal packages and
feature modules to recieve live events and continually process updates from our
code as opposed to just handling discord events.

- PublishEvent()
  In this specific implementation anyone may become a Publisher by calling
  PublishEvent() on any structure that implements the Event interface. This
  provides for modules being able to define their own event types (so long as
  they also extend the central enum of EventType in state.go).

- SubscribeWithHistory()
  This returns a channel to the caller that returns copies of any event matching
  the input event type. This channel will be prepopulated with up to 256 most
  recent events already in the cache. Future work will make this number configurable.
  Each event published will be sent down all relevant channels at publish time.

- Subscribe()
  This returns a channel to the caller, as SubscribeWithHistory also does,
  with the sole caveat that there are no historical "old" cached events
  prepopulating the channel.

Finally, this commit also contains tests

bingobot

Getting started

To make it easy for you to get started with GitLab, here's a list of recommended next steps.

Already a pro? Just edit this README.md and make it your own. Want to make it easy? Use the template at the bottom!

Add your files

cd existing_repo
git remote add origin https://gitlab.com/whom/bingobot.git
git branch -M main
git push -uf origin main

Integrate with your tools

Collaborate with your team

Test and Deploy

Use the built-in continuous integration in GitLab.


Editing this README

When you're ready to make this README your own, just edit this file and use the handy template below (or feel free to structure it however you want - this is just a starting point!). Thanks to makeareadme.com for this template.

Suggestions for a good README

Every project is different, so consider which of these sections apply to yours. The sections used in the template are suggestions for most open source projects. Also keep in mind that while a README can be too long and detailed, too long is better than too short. If you think your README is too long, consider utilizing another form of documentation rather than cutting out information.

Name

Choose a self-explaining name for your project.

Description

Let people know what your project can do specifically. Provide context and add a link to any reference visitors might be unfamiliar with. A list of Features or a Background subsection can also be added here. If there are alternatives to your project, this is a good place to list differentiating factors.

Badges

On some READMEs, you may see small images that convey metadata, such as whether or not all the tests are passing for the project. You can use Shields to add some to your README. Many services also have instructions for adding a badge.

Visuals

Depending on what you are making, it can be a good idea to include screenshots or even a video (you'll frequently see GIFs rather than actual videos). Tools like ttygif can help, but check out Asciinema for a more sophisticated method.

Installation

Within a particular ecosystem, there may be a common way of installing things, such as using Yarn, NuGet, or Homebrew. However, consider the possibility that whoever is reading your README is a novice and would like more guidance. Listing specific steps helps remove ambiguity and gets people to using your project as quickly as possible. If it only runs in a specific context like a particular programming language version or operating system or has dependencies that have to be installed manually, also add a Requirements subsection.

Usage

Use examples liberally, and show the expected output if you can. It's helpful to have inline the smallest example of usage that you can demonstrate, while providing links to more sophisticated examples if they are too long to reasonably include in the README.

Support

Tell people where they can go to for help. It can be any combination of an issue tracker, a chat room, an email address, etc.

Roadmap

If you have ideas for releases in the future, it is a good idea to list them in the README.

Contributing

State if you are open to contributions and what your requirements are for accepting them.

For people who want to make changes to your project, it's helpful to have some documentation on how to get started. Perhaps there is a script that they should run or some environment variables that they need to set. Make these steps explicit. These instructions could also be useful to your future self.

You can also document commands to lint the code or run tests. These steps help to ensure high code quality and reduce the likelihood that the changes inadvertently break something. Having instructions for running tests is especially helpful if it requires external setup, such as starting a Selenium server for testing in a browser.

Authors and acknowledgment

Show your appreciation to those who have contributed to the project.

License

For open source projects, say how it is licensed.

Project status

If you have run out of energy or time for your project, put a note at the top of the README saying that development has slowed down or stopped completely. Someone may choose to fork your project or volunteer to step in as a maintainer or owner, allowing your project to keep going. You can also make an explicit request for maintainers.
