NTD folks. Good stuff Brandon. Thank you. 00:37:32 Ramkumar Chinchani: olareg is the only registry that is happy currently? 00:38:10 Ramkumar Chinchani: is there a priority list for these tests? ecosystem tooling may work just fine even with some failing tests. 00:38:31 Tianon: I had some minor patches to https://pkg.go.dev/cuelabs.dev/go/oci/ociregistry/ocimem that had it happy for a while, but then Brandon kept adding more tests and broke it again in ways that were harder to fix 😂 00:39:22 Ramkumar Chinchani: Worry is we are focusing only on the server side. What if clients break when we fix the registry this way. 00:40:06 Ramkumar Chinchani: zot has client tests, so we will know soon enough 00:40:24 Ramkumar Chinchani: all of the above 00:41:36 Ramkumar Chinchani: baby steps 00:44:56 Jory Burson: Get it together Jeff 00:45:04 Jory Burson: jk 00:50:06 Brandon Mitchell: uses: sudo-bmitch/distribution-spec@pr-conformance-v2 00:51:01 Tianon: Replying to "uses: sudo-bmitch/di..."
