Unable to generate glide.lock when testImport is being used

[HelloGrayson]

I'm trying to move my libs test deps out of import and into testImport, so that my lib doesn't impose constraints on my users test dependencies.

I've updated my glide.yaml to move the test deps into testImport:

package: github.com/yarpc/yarpc-go

import:
- package: golang.org/x/net
  version: master
  subpackages:
  - context
  - context/ctxhttp
- package: github.com/thriftrw/thriftrw-go
  version: ~0.1
- package: github.com/uber/tchannel-go
  version: ^1.0.9

testImport:
- package: github.com/stretchr/testify
  version: master
  subpackages:
  - assert
  - require
- package: github.com/golang/mock
  version: master
  subpackages:
  - gomock
- package: github.com/crossdock/crossdock-go
  version: master

But when I run glide up I get the error Failed to generate lock file: Generating lock produced conflicting versions of github.com/golang/mock. import (), testImport (master):

yarpc/yarpc-go - [move-test-deps] » rm -rf vendor

The version of glide at hand is 0.12.0:

$ glide --version
glide version 0.12.0-dev

And there is a branch to reproduce this here, just run this:

$ git clone [email protected]:yarpc/yarpc-go.git
$ git co move-test-deps
$ glide up

Is there a way to dump more info about the error?

[aeneasr]

I can confirm this. I am using the latest master (because no easy way to install binaries on windows).

Neither of these two above yaml files produce an error for me with the current release of glide (0.12.3); however, I ran into a very similar problem. I'm not sure if this is the entire problem or not, but I think what is happening is that:

1. Top-level glide.yaml indicates that pkg-A and pkg-B are testImport
2. During glide update, glide notices that pkg-B has a Godeps.json that depends on pkg-A
3. Glide loads pkg-A as an import even though it came in via a testImport Godeps
4. Conflict if pkg-B -> pkg-A (import) is a different version from pkg-A (testImport).

I think common packages are almost certain to cause this problem; my conflict was on go-diff, which is a dep of testify, and my workaround was to move go-diff from a testImport to an import in my glide.yaml since import package versions trump testImport package versions.

[glibsm]

Ran into the same problem.
Can confirm that moving to regular import works (@novas0x2a solution)

[mwf]

I ran into the same problem.

It's interesting.
After moving testImport to import and making glide up I moved the dependencies back to testImport. Then ran glide up again, and it ran without errors!

[stevenroose]

I think the best solution easiest workaround is to don't have a version constraint on your test dependencies.

[aeneasr]

I think the best solution is to don't have a version constraint on your test dependencies.

I strongly disagree

[stevenroose]

@arekkas well, "best solution" might have been a bad expression of what I meant. Let me rephrase to "easiest workaround".

[hoshsadiq]

Not having a version constraint doesn't work either:

package: company/team/myapp
testImport:
- package: github.com/imdario/mergo

resulting in the following error
