What version of Go are you using (go version)?

$ go version
go version go1.12 darwin/amd64

Does this issue reproduce with the latest release?

Yes.

What did you do?

go mod vendor

What did you expect to see?

Process finishing / retrying.

What did you see instead?

Program randomly gets stuck on version selection. Checking the process tree reveals it to be waiting for git ls-remote. This happens on private repos to which access is configured via insteadOf https to ssh rewrite in .gitconfig and on public repos (e.g. spf13/pflag).

Can you give us the exact repro steps ?

Can you send a SIGQUIT (Ctrl + \) to the process when it gets stuck and post a goroutine trace ?

Not really any steps involved, it just stops doing anything most of the time for me - very likely waiting for git ls-remote to do anything.

This trace is from a mod init - but it runs into the same issue.

Even I'm facing the same issue. Below is the SIGQUIT logs. This happened when I'm trying to move from dep to go modules. Tried removing Gopkg.toml and lock but didn't help much.

@rajuGT, that doesn't look like the same issue — the goroutine dump you've provided seems to be waiting on a locked file (perhaps one held by a different go command?), not on a git ls-remote subprocess.

@schittler, does this still reproduce for you on Go 1.13.3?

If so, does git ls-remote produce the same behavior when you invoke it directly from the command line? Is there a pattern to which servers the git command hangs against?

I suspect that this is either a git bug or a problem with the git server you're connecting to, but without more detail it's hard to be sure.

I don't use this exact setup anymore, so I can't say. My suspicion is that it was related to our work network and git not detecting a hung connection.

@ylallemant had the same problem through, maybe he can weigh in on this issue.

Timed out in state WaitingForInfo. Closing.

(I am just a bot, though. Please speak up if this is a mistake or you have the requested information.)
