On this Friday night, I decided to give my mini Python to pseudo-Michelson compiler ¹ a little polish. I remembered leaving it working flawlessly, so that it’d be easy to get back grinding at it anytime I so desired to. Using the Python AST module as a compiler frontend, I was sure it’d be pretty stable, unlike Marshall code, purposely left undocumented ².

So I gave my code a go, and somehow, my integration test wasn’t working anymore! What could possibly have gone wrong. I noticed I was using the Python 3.8 interpreter and that I had only tested my code on Python 3.7. Could this update contain breaking changes with respect to my code? I figured if this had been the case, then surely it’d be in the AST module. I compared the bytecode output I was getting with the one my test expected and surprisingly, it was not the same! It wasn’t pushing my constants onto the stack when assigning them to variables. A little more digging, with the help of Python’s new breakpoint(), until I noticed that my condition on ast.Num, to push a number on the stack, had been replaced by ast.Constant… Hence the weird bug I was noticing. A little Googling to find that indeed:

By default, npm install -g tries to write a root-writable directory and greets you with:

Django-autocomplete-light 3.5.0 was released, including backward compatibility breaks.

Django-autocomplete-light 3.4.0 introduced a regression in locale loading, it has been reported by Phil Gyford, thank you !

This release re-enables Python 2 and Django 1.11 support, even though it doesn’t pass all tests because tests rely on dicts being ordered by default which came in Python 3

Also, this release exits from using Django’s vendored select2, and vendors select2 itself with a submodule again, this is to benefit from upstream bugfixes faster

A Delegative Democracy implementation made in BlackLoop HackerSpace for Les Indignés back in the days I used to squatt hackerspaces in-between gigs (now running my own). It’s a bit old but probably still valid, given the complexity is handled in SQL with a WITH RECURSIVE query. Anyway, hope this will inspire you ! Have a great week

Pretty nice alternative docstring syntax for argument description and much more !

Dynamic Environment is when your pipeline creates a branchname.example.com deployment, for integration tests or manual review.

Gitlab in autodevops mode and with Kubernetes lets you enjoy this kind of stuff by just starting projects from their template images. Note that YourLabs offers consulting if you need help to setup/maintain your baremetal K8S or GitLab instance to do this kind of thing. (Please forgive horrible sound recording in our demo)

This article however, demonstrates how to acheive dynamic environments for integration testing and reviews with the product team with just docker-compose and nginx-proxy.
