bors-ng VS cache

You can further protect main branch by using a rollup approach (see Bors for an example) where the pre-merge tests are run against the combination of those PRs currently proposed for merging, which limits the possibility that two PRs look OK but together break something.

Completely independent implementations of the same underlying concept, one of which was written pretty much just for the rust project, and the other was written as a more general tool and service.

Merge commit (via bors) because I hate squash merges.

Maybe the author does not know that there's https://bors.tech which is a publicly available Bors instance. There's absolutely no operational cost involved except for the initial setup.

Or images. On pages like https://bors.tech and https://foodpartners.us the "bloat" is all images. The images are bigger than they were in the 1990's because they look better, even if you don't think they communicate more "information" people may still want them.

According to the README, it bisects. It doesn't matter much for me, though - the batches in our case were never big.

Sounds like they settled on the bors model of a batching merge queue. Gitlab's merge trains instead speculatively run all of the merges at once which gives more precise data at a higher cost and longer time, if your number of parallel runners is limited.

There's https://github.com/actions/cache though?

Use Cache Actions: GitHub Actions provides cache actions that simplify caching implementation. The @actions/cache JavaScript library is a popular choice for managing caching in workflows. It offers flexible options for storing and retrieving cache artifacts based on keys, scopes, and paths.

GitHub maintain a set of repos called actions. One of which is called cache.

By utilizing the actions/cache action action, we implemented a strategy to store and retrieve dependencies, preventing redundant installations.

I do think it's good practice to enable caching, such that your script doesn't hit RubyGems / pip / npm / etc every time it runs.

That way at least the automation activity stays entirely within the GitHub / Azure network.

It looks like you can do that for Ruby by adding this:

You could try to find some point in the process where you can set up Actions caches with actions/cache, otherwise Container customization for Self-Hosted Runners is currently in Beta.

I would configure Github Actions cache so Docker doesn't have to compile all layers from scratch every time

In the copied example, npm caching is done via actions/cache@v2 action. But we can simplify our workflow by dropping this step and using built-in functionality for caching
