dep double clones goconvey

[sullimander]

When converting to using glide to dep with a repo that uses goconvey for testing, dep appears to be cloning goconvey incorrectly. I created an example repo here: https://github.com/skisulli/dep-issue.

What version of Go (go version) and dep (git describe --tags) are you using?

$ go version
go version go1.8.3 darwin/amd64

$ git describe --tags
v0.1.0-224-g88277ad

What dep command did you run?

I replaced the real absolute paths with $GOPATH in the output.

$ dep init -v
Importing configuration from glide. These are only initial constraints, and are further refined during the solve process.

What did you expect to see?

I expected my tests to pass as they did when ran with a vendor directory built with glide.

$ make test
go test -v `go list ./... | grep -v /vendor/`
=== RUN   TestMain

  The test doesn't matter for this example ✔

What did you see instead?

My tests failed. When looking into the error, the issue seems to stem from dep cloning github.com/smartystreets/goconvey into two places, /vendor/github.com/smartystreets/goconvey and /vendor/github.com/smartystreets/goconvey/convey.

hi @skisulli - thanks for the issue!

Looks like we do have a bug here, but it's in the glide importer. Sorta, at least. Constraints must be declared on a project root, and github.com/smartystreets/goconvey/convey is not a root - github.com/smartystreets/goconvey is. The glide importer should check to make sure of that, and take some corrective action (perhaps, slicing it down to the root).

What really sucks is that I apparently forgot about getting the validation in to make sure that we only allow project roots in Gopkg.toml, before doing any other work. That would be #697, I think. We may only be able to make that a warning now, to preserve the backwards-compatibility guarantee 😢

[sullimander]

@sdboyer thanks for the update. I was able to get it working by switching the constraint in the Gopkg.toml to be github.com/smartystreets/goconvey.

We ran into the same problem with the glide importer at gophercon. I have a fix locally that I just need to add tests for and then submit the PR.

[vincentbernat]

Hey @carolynvs! Could you share the fix? Maybe someone would write the tests for you.

[carolynvs]

Oops, this was fixed in #898 and I forgot to close this issue. Are you still running into this problem on the latest build of dep?

[vincentbernat]

No, I didn't test! It works fine now. Thanks!
