Python-Os

bro claims he wants to learn about os but programs in python

Reason for doing this

This is my second time going through OStep, yet I can't quite seem to get my fundamentals down. Must be reason for unemployability. booboo. Will add design decisions in the future once I get a formal idea of how to model this and how far I wish to go.

Todo:

• Implement I/O simulation

• Implement MLFQ Scheduler

• Implement Lottery scheduler

• Implement Completely Fair Scheduler (CFS)

  • Potentially implement own red-black tree
  • Potentially incorporate priority

• Implement basic File System with JSON storage

  • Separate out file system and storage manager class,
    • This is for potentially exploring RAID, SSD, disk, WAL, etc.

• Build memory management model

  • Explore malloc heap allocation policies
    • More elaborate schemes, eg: Buddy fit
  • Build per-process memory allocator model
    • Basic (base and bound)
    • Segmentation
    • Paging

• Improve logging for monitoring of various components

  • Note: Stretch goals because I presently have no intentions of incorporating external dependencies into this model yet.
  • But ideally I wish to be able to isolate logging not only by levels but by components as well.
