Brian #1: Correcting Documentation for a Deployed Python Package

  • "A clever way to release new documentation without releasing a new package that might confuse your user base.”
  • Upload changes to pypi without bumping the version by using post release version numbers: 0.3.2 => 0.3.2.post1
  • Prevent documentation issues by using restview --long-description before uploading. (or use md and really any md converter)

  • Schemas validation, template engine, sessions and many more features were written from scratch to provide great performance along with an elegant async interface.
  • Vibora also take advantage of multiple CPU cores by default thanks to the multi-processed architecture. Uvloop and other C speed-ups are used when available.

  • Deployment has its own HTTP app server
  • Docs need help
