Hi Eric, Thanks for the call yesterday.
Similar to other cases we covered yesterday, and unlike stated above, the translation of the alias in "snap get system" to "snap get core" is actually made inside the daemon, so there shouldn't be any difference in results, whether via the command line or via the API. The following excerpt is a plain copy & paste from my terminal just now: [niemeyer@nomad ../snapcore/snapd]% sudo curl -s --unix-socket /run/snapd.socket http:/v2/snaps/system/conf | sha1sum d3f0bde1349f24893cc64573a6706f0065abb505 - [niemeyer@nomad ../snapcore/snapd]% sudo curl -s --unix-socket /run/snapd.socket http:/v2/snaps/core/conf | sha1sum d3f0bde1349f24893cc64573a6706f0065abb505 We share the values you raised, and we try hard not to make incompatible changes, whether in a minor or not (releasing breaking changes often is a pain, even if clearly labeled as such). An example where we've failed to do that, though, is the result of the /v2/interfaces API. It will indeed return an alias where before it would not, so this is a potential breaking change that we should have been more careful about, and per the conversation yesterday we'll be happy to revert if it becomes necessary. Ironically, precisely because we share the values of respect for greater API stability, we won't revert this change unless it is necessary, because our most recent stable release now presents that behavior already, and it's out there for a while. So reverting the change means modifying the behavior in a stable release, and that needs to be carefully considered among the other options. That's why in our call yesterday I explicitly asked what is the current impact of that change, and you said the issue is under control and reverting it won't bring a direct benefit to you. That's again confirmed above. So unless we receive further feedback indicating the pros of reverting outweigh the cons, my recommendation is for the change to remain in. As always, we remain available for further discussing this specific issue, the concept of API stability in general, and testing approaches to mitigate such issues in the future. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1791814 Title: [2.35.1] /v2/interfaces returns "system" instead of "core" as owning snap of core interface slots To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1791814/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
