@Andriy Knysh (Cloud Posse) I have 5 PRs incoming to tackle the recent flakiness. It's partly due to the harden-runners, but also other things like windows defender scanning every file we unpack from the cache. Turning that off for cache unpacking reduces time from 5-10m to 1m.

Here's the first PR in the series. github.com/cloudposse/atmos/pull/3037

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/3039/changes (small one)

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/3040 since we run on spot instances, and run quite a lot of jobs, there's some % that get interrupted simply by infrastructure issues. This is introduces a job that runs when workflows complete and inspects why they failed; if it is related to losing connections to the github control plane, instances getting shutdown, etc, it will retrigger them automatically.

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/3022 finally ready after 20+ rounds of fixing races and shuffling tests. This increases overall stability.

@Andriy Knysh (Cloud Posse) small one: github.com/cloudposse/atmos/pull/3050/changes

@Andriy Knysh (Cloud Posse) since our release drafter keeps failing due to exceeding the release notes size, this introduces OpenAI summarization using a new mage target.

https://github.com/cloudposse/atmos/pull/3045

@Andriy Knysh (Cloud Posse) this introduces runtime process metrics, terraform plan/apply stats, and output in atmos so we can track and sent to atmos pro, when enabled. I collaborated on this PR so I cannot approve.

github.com/cloudposse/atmos/pull/2926

@Andriy Knysh (Cloud Posse) this addresses one of the windows flakes we've been seeing
github.com/cloudposse/atmos/pull/3057

@Andriy Knysh (Cloud Posse) this converts a shell step to a mage target with tests. We have the aggregate jobs that wait for the success of the shards so we can require them to pass. There was a flake in waiting for the conclusion, which isn't always immediately available after the shards complete.

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/3041

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/3038

@Andriy Knysh (Cloud Posse) this has a 3-4x speed up in GH cache operations on windows by using the d:\ drive instead of c:\ ; e.g. cache restores taking 1.5 min instead of 6 minutes.

@Andriy Knysh (Cloud Posse) cut a release once these merge today, if you happen to be around. github.com/cloudposse/atmos/milestone/3

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/3024

@Andriy Knysh (Cloud Posse) this fixes a bug where concurrent website deploys would result in a corrupt deployment. This is something that started happening due to more rapid merges due to merge queues.

@Andriy Knysh (Cloud Posse) more defensive logic for flakes

Hey folks, these 2 are ready 🙌 :

github.com/cloudposse/atmos/pull/3084 🐇 is ignoring me 😢

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/3077 warm our build caches

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/3069 this extends our version tracker to support arbitrary YAML files in addition to the JSON files already supported. Also it allows the version to be preprocessed prior to writing.

@Andriy Knysh (Cloud Posse) since we've already solved all the race conditions in our tests and ensured they pass with shuffled order, it was pretty easy to now massively parallelize all our tests. Code rabbit cannot approve though since it modifies more than 150 files; however all the changes are more or less the same: adds t.Parallel everywhere. The only exceptions are where we update the mage files to increase parallelism to use it.

wow, I missed that you merged my helm prs, thank you guys! sorry that it took so long, was distracted with other tasks 🎉

@Andriy Knysh (Cloud Posse) more flakes github.com/cloudposse/atmos/pull/3158

Heyy folks. I have another feature ready for feedback 👉️ github.com/cloudposse/atmos/pull/3119
Keen on your thoughts!

@Andriy Knysh (Cloud Posse) here's a PR stack that refactors all of our tests to use a GitHub facade. Plus, adds support for GHES.

This is to reduce flakes, and speed up tests.

It works by creating a gitmirror and emulating the GitHub API in front of it for the calls we need. In order to use it, we needed to support custom GitHub endpoints, hence we went ahead and added GHES support and use that to point it at the local mock http started by the test runner.

Review in order. Approve in order. Then merge as a stack.
