What version of Go are you using (go version)?
go version go1.8 darwin/amd64

What operating system and processor architecture are you using?
macOS Sierra

What did you do?
dep init on a project that depends on the master branch of Kubernetes' Go Client.
(Latest commit as of writing this issue)

What did you expect to see?
For it to install the Kubernetes Go Client and its dependencies.

What did you see instead?

solve error: No versions of k8s.io/client-go met constraints:

Specifically the second line:

master: Could not introduce k8s.io/client-go@master, as it requires package github.com/emicklei/go-restful/swagger from github.com/emicklei/go-restful, but in version master that package is missing.

It is indeed true that go-restful has removed the package swagger, but I expect for it to try the other versions too or at least the latest tagged release/version.

Retrying dep init makes it say it cached the library and so it succeeds for some reason.

Thanks for the detailed issue report 🎉 ! There are a few things going on here.

Specifically the second line:

master: Could not introduce k8s.io/client-go@master, as it requires package github.com/emicklei/go-restful/swagger from github.com/emicklei/go-restful, but in version master that package is missing.

It is indeed true that go-restful has removed the package swagger, but I expect for it to try the other versions too or at least the latest tagged release/version.

Ordinarily, it would; failure at that point should trigger guided backjumping, causing the solver to go back and (eventually) start trying different versions of go-restful, then make it back to k8s.io/client-go, at which point it would work. However...

Retrying dep init makes it say it cached the library and so it succeeds for some reason.

This is the key here. There are still occasionally some issues when the solver triggers a bunch of initial clones (which happens on a lot when you first run the tool); some seem to fail, time out, or something in a way that we don't correctly catch. On a subsequent run, once those heavy clones are already done, things are generally much smoother.

That's not saying it's OK, of course - and we're working on it 😄 . I'm in the process right now (sdboyer/gps#196) of refactoring a lot of how the source management is handled in a way that could eliminate problems like this. Even if it doesn't directly, though, we'll have much tighter control and more ability to figure out what actually IS going on.

In the meantime, though, it would be helpful to get more output for this problem. Could you rm -rf $GOPATH/pkg/dep, then run dep init -v? I suspect that what's happening is non-deterministic (due to dependencies on goroutine scheduling and network interaction), so it's unlikely that exactly this same issue would recur. But a) if it does, it's likely a different problem, and b) even if it doesn't, the fuller trace would be helpful for understanding the context of what you've already reported.

Following what you said and resetting the vendoring, lock, and manifest before running dep init -v does reproduce the problem. Here are the logs with some of the package somewhat censored, those are indicated by surrounding *s.

Rerunning it doesn't seem to solve the issue like I thought it did. But when I resetted my repo to the state where I had my manifest and lock, the first dep ensure -update would fail and the second one succeeds. However if I then resetted my vendoring and $GOPATH/pkg/dep again, it would keep failing the second time too. However a third time seemed to be the charm then. This is odd. Below are the logs. It perhaps has to do with some goroutines because the resolution seems random.

Ahhhh, I think I know why this is happening!

I'm pretty sure that there are errors happening on the calls made to retrieve the lists of available versions for a given dependency (SourceManager.ListVersions()). That's why we see this:

(10)  ← backtrack: no more versions of github.com/emicklei/go-restful to try

Even though there are obviously more versions of that dependency that could be tried. The problem is, while errors resulting from calls to ListVersions() do cause the solver to abort appropriately, they're stored in such a way that they don't actually get reported properly in results. Thus, we see these misleading errors that tell us there are no more versions to try, when the actual problem is that we failed to retrieve the rest of the list.

Fixing the reporting problem shouldn't be too hard. I suspect that the underlying problem will end up being solved by the aforementioned sdboyer/gps#196.

Sweet, it isn't that big of a deal as it resolves itself after a while. The tool already is miles better than the other existing ones in terms of consistency.

oh, this one should be closed out, the underlying issues here should now be mostly addressed.
