| # We need to avoid running concurrent tests using the same commit SHA and | |
| # writing to the same image-repository. If we do not then we could see false | |
| # positive test results if one of them doesn't actually push cache layers. We | |
| # address this problem by: | |
| # | |
| # 1. Ensuring tests which run in parallel either use separate image repositories | |
| # or different Git commit SHAs. We also need to take care to ensure that | |
| # builds on `main` are accessible as cached layers for PR images. | |
| # 2. Utilizing concurrency groups to avoid having multiple instances of this | |
| # workflow run in parallel when triggered on the same commit SHA. | |
| # 3. Deleting the `cache-sha-*` tags to ensure our running workflow produced | |
| # those images. Ideally, we'd delete these before the tests run but attempting | |
| # to delete images from non-existing packages causes failures so this works | |
| # well enough. | |
| # | |
| # I also considered revising the action to avoid pushing images entirely. | |
| # Doing this may be challenging in otherways as pushing the image is a | |
| # requirement for getting the digests in some contexts: | |
