Cannot vendor github.com/lib/pq

[stub42]

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

go version go1.8.3 linux/amd64

What dep command did you run?

In a hello world example:

package main

import (
	"fmt"
	_ "github.com/lib/pq"
)

func main() {
	fmt.Println("vim-go")
}

I ran:

dep init -v

What did you expect to see?

github.com/lib/pq vendored like any other dependency

What did you see instead?

A confusing failure. Not a git repository, but enough of a git repository to see the remote branches?

Cleaning out $GOPATH (removing $GOPATH/pkg and everything in $GOPATH/src that isn't mine) got it working. Something being used as a cache in here must have been bogus.

[darkowlzz]

Thanks for reporting. I think we had similar issues before dep v0.1.0, which was fixed before the release.
@stub42 can you check your version of dep? (git describe --tags in $GOPATH/src/github.com/golang/dep directory)

[stub42]

I have been testing trunk, so probably 77df563 .

govendor and 'go get' where the other tools that might have pulled things in.

[kron4eg]

Same go file, with current dep master g4bfa359

@stub42 probably you use git submodules, inside docker maybe. I saw such case when .git inside container gets detached from it's main database.

[stub42]

No submodules or containers involved. Per #790 (comment) vendoring with dep worked again after I cleared out $GOPATH/pkg, so I'm assuming something non-standard ended up in here (like an empty directory where dep expected a git repo). Any evidence has been destroyed, so maybe just close this issue unless recovery can be done (ignore or remove the broken local copy and use the remote repo).

[sdboyer]

yeah, this is most likely a case of failure to terminate subprocesses gracefully on interrupt. it's a known issue - we just went for a lowest-common-denominator that would work cross platform, but it's too harsh, using os.Process.Kill(), which doesn't give e.g. git a chance to clean up after itself.
