-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Andrew has a patch up today that allows simplestreams to keep searching if it hasn't found what it wanted in a given stream: https://code.launchpad.net/~axwalk/juju-core/lp1233924-simplestreams-getmetadata-fallback/+merge/188758
There are 2 thoughts on this, so I wanted to bring it up for discussion. We came to this because the Azure provider was adding the "daily" stream to the search path. Which meant that we would find the daily stream, parse it, not find anything and then stop. Without falling back to the releases stream which has the actual entries we are looking for. (We "solved" this by just removing the daily stream, which was also for other reasons.) I believe the current behavior is for people that set up their own images. Then when we ask for "precise" we will see the one they set up (say in their private-bucket, or at a custom imagemetadata-url). If they don't set up a "saucy" image, then when asked for one, rather than giving them a *stock* saucy we just give them nothing. I can understand a bit the idea of "if I ask for something incorrectly, don't give me something I don't want". But I think most users would actually be served best with fallbacks enabled. So if you set up a custom "precise" image, we'll use it when asked, but if you ask for anything else, you still get the stock images. I can see a user wanting the existing behavior (I'd rather it fail early than start something that isn't actually what I want). But I don't think it should be our default behavior. I feel strongly enough that I think we can just land his patch and then file a bug about "if users want this, we can do it in this way". Thoughts, concerns?
