Some neat things came alongside the migration: + * All libraries that define the __version__ attribute can be accessed with “libname.__version__” (like adafruit_bme680.__version__) which hopefully helps with support and debugging. This wasn’t true beforehand if the library was installed from PyPI via pip. + * Problem matchers are fixed for the CIs, so the CI should give clearer, more recognizable responses when failing, which should alleviate some of the parsing reviewers and submitters have to do currently. + * Requirements now have a single home in requirement.txt instead of two places like before. Optional dependencies used only in examples or optional features (like pillow) can now be put in the new optional_requirements.txt. These can be downloaded using “pip install libname[optional]” + * e.g, pip install adafruit_bme680[optional] + * Pure python wheels (built distribution) are uploaded to PyPI which should cut down on install times, since packages won’t need to be built from source distributions after downloading. Source distributions are still uploaded for redundancy. + * Submitted PR for Adafruit IO updates + * Fixed the adabot reporting errors + * Submitted draft of fix for circuitpython.org Library Infrastructure issues list, now pending a few more additions and getting it to pass the CI +* This week + * @neradoc raised a good point that the current version string that gets replaced isn’t PEP 440 compliant, so a patch to the libraries would help with manual and editable installs of the repository via pip + * Finalize the Library Infrastructures fix + * Host the CircuitPython Day sprint! Come join and hack away at issues! + + +## 38:00 In The Weeds +38:37 @foamyguy - On-Device Testing: +* Self-hosted github actions runners. Can use Raspberry Pi or other computer as an actions runner to run some of the tasks inside of our actions workflows. I was successful in setting up a PoC that uses this to retrieve memory measurements from a connected microcontroller and report them in the actions output. Mine was on a single repo, but if I understand correctly it’s possible to set them up at the organization or enterprise levels within Github. + * Pros: + * Fairly easy to set up + * Infrastructure already exists + * Very versatile. Actions can do almost anything so we could evolve the types of on-device measurement and testing we perform without having extra work on the infrastructure + * Cons: + * Github recommends to only use self-hosted runners for private repos because PRs can modify the actions workflows and trigger arbitrary code to run on the runners. Maybe we already do, or could restrict actions to only run automatically for approved / existing contributors and require approval to run for new contributors? + + * Custom infrastructure as a “go between” for actions tasks and our on device test runners. One idea is a web server that provides endpoints for HTTP requests to trigger the specific measurements and tests that we want to run. Runners connect to the server via websockets or long-polling and wait for jobs to carry out. + * Pros: + * Can be more restricted than actions so that arbitrary code execution won’t be possible + * Cons: + * Have to create, maintain, and possibly host the infrastructure. +59:19 @fede2 + * The Open Source Security Foundation (OpenSSF) has a tool called Scorecard, that reviews the security practices of a “repo” with basic things like reviews, 2FA, dependency pinning. Is it worth it to start working on a Scorecard for the Circuitpython repo? +Note: CircuitPython has a current score of 5.5 +Adafruit has an average of 4.3, and uses scorecard on 4.68% of their repos + * Pros: + * Improve security practices of the organization, teach security practices to collaborators. + * Removes or makes it hard for attacks to get into the code. + * This repo already uses lots of good security practices, this will make them more visible. + * Good security practices learning guides might come out of this. + * Cons: + * Version pinning takes time to get used to, but should not make it harder to test new versions of dependencies. + * It’s a gradual process that takes non-dev time from core devs. + * Best Practices Badge is a “dependency” of scorecard, so I’ll have to work on this as well. + + +## 01:11:07 Wrap-Up +Next meeting is 22 August 2022, as usual.
