GSoC 2022

Placeholder for tasks that could be undertaken in this year's GSoC.

Ideas (extracted from the "dev" ML):

  1. Redesign and modularize the "ml" package
    -> main goal: enable multi-thread usage.
  2. Abstract the linear algebra utilities
    -> main goal: allow switching to alternative implementations.
  3. Redesign and modularize the "random" package
    -> main goal: general support of low-discrepancy sequences.
  4. Refactor and modularize the "special" package
    -> main goals: ensure accuracy and performance and better API,
    add other functions.

Other suggestions welcome, as well as

  • delineating additional and/or intermediate goals,
  • signalling potential pitfalls and/or alternative approaches to the intended goal(s).
Difficulty: Minor
Project size: ~350 hour (large)

James Server

Adopt Pulsar as the messaging technology backing the distributed James server

https://www.mail-archive.com/server-dev@james.apache.org/msg71462.html

A good long term objective for the PMC is to drop RabbitMQ in
favor of pulsar (third parties could package their own components using
RabbitMQ if they wishes...)

This means:

  • Solve the bugs that were found during the Pulsar MailQueue review
  • Pulsar MailQueue need to allow listing blobs in order to be
    deduplication friendly.
  • Provide an event bus based on Pulsar
  • Provide a task manager based on Pulsar
  • Package a distributed server backed by pulsar, deprecate then replace
    the current one.
  • (optionally) support mail queue priorities

While contributions would of course be welcomed on this topic, we could
offer it as part of GSOC 2022, and we could co-mentor it with mentors of
the Pulsar community (see [3])

Would such a plan gain traction around here ?
