Only return one image ID, and hopefully a more precise one, from pulling. #2202
Conversation

Ephemeral COPR build failed. @containers/packit-build please check. |

Interesting. Do you think this would also fix the expected-layer-diffid error that I'm seeing in #24280? |
|
Completely unrelated, please file that separately. |
|
I would if I could reproduce it. I'll keep trying tomorrow. |

In containers/podman#24287 I have confirmed that we now no longer output two IDs, and the test seems to be passing. This is ready for review. |

There was a problem hiding this comment.
Should be nil, to make it clearer to future maintainers.

If we can't find the image we have just pulled by digest, the image was probably already removed, and returning candidate.Value could only possibly point at a _different_ image with the same tag. Instead, fail immediately. Signed-off-by: Miloslav Trmač <mitr@redhat.com>
There's no benefit in returning multiple matches; we ideally want to return exactly the image we pulled, but even if that were hard, returning multiple guesses is not what the user asked for. Signed-off-by: Miloslav Trmač <mitr@redhat.com>
... because we now never return more than one. Should not change behavior. Signed-off-by: Miloslav Trmač <mitr@redhat.com>
- Use the image's repo, not just the digest, to be more precise when zstd:chunked ambiguities are involved - Remove the multi-platform lookup code, it is never used Signed-off-by: Miloslav Trmač <mitr@redhat.com>

This should fix containers/storage#2130 (comment) .
Untested at this point.Reading the code makes it tempting to keep refactoring and improving, but to keep the scope reasonable, I have just added FIXMEs.
