#pubgrub — Public Fediverse posts

I'm trying to understand / implement dependency resolving using the pubgrub algorithm (to use in my buildsystem nitto). But I keep running into bugs; The newset one:

Suppose we have the following state:
```
root 1.0.0 -> foo ^1.0.0, bar ^1.0.0
foo 1.1.0 -> bar ^2.0.0
foo 1.0.0 -> n/a
bar 1.0.0 -> n/a
bar 1.1.0 -> n/a
bar 2.0.0 -> n/a
```

Now after avoiding a conflict and by choosing to not select `foo 1.1.0` and deriving `not foo 1.1.0` from `{foo 1.1.0, not bar ^2.0.0}`, it derives `foo ^1.0.0` from `{root 1.0.0, not foo ^1.0.0}` even tho it is already an derivation term in the assignments! Aparentily it relates `not foo ^1.0.0` as as overlapping, and wants to add it again to the partial solution...

@Abhi_Ram chuckling. I crave wings, beer and nachos after my #hikes. Like to think of it as a congratulatory #ABitOfKindness for my body, post #hike. #PubGrub

As @getajobmike said, lots of great improvements in Bundler 2.4 but for me no longer having some of the most confusing output about dependency resolution blockers is a gigantic improvement, especially for less experienced folks who could feel paralyzed by the previous output on resolution failure. https://bundler.io/blog/2023/01/31/bundler-v2-4.html

Thanks to David Rodríguez, @jhawthorn, and @nex3 for their incredibly helpful work.

When I returned to the UK, gammon, egg & chips was one of the first #pubgrub dishes that I had to hunt down. I adore it and it is stupidly easy to cook at home once you have the timings sorted!
