go get creating strange git messages in bash. Any ideas what causes this ?

[Joe Blue]

hey all,

Does anyone know why "go get" causes the follow weird git messages ? This does NOT happen with al git repos i have found.

a simple example:

````

x-MacBook-Pro:pkg apple$ go get github.com/pkg/sftp

x-MacBook-Pro:pkg apple$ go get -u -v github.com/pkg/sftp

github.com/pkg/sftp (download)

# cd /Users/apple/workspace/go/src/github.com/pkg/sftp; git pull --ff-only

    git pull <remote> <branch>

package github.com/pkg/sftp: exit status 1

x-MacBook-Pro:pkg apple$ 

````

a bigger example.

go get -u -v github.com/spf13/hugo

x-MacBook-Pro:godev apple$ go version

You have a few repos that aren't on a branch, so git can't pull and fast forward. You can checkout master in those repos, or delete them altogether and the next `go get` will fetch the current master branch.

[Joe Blue]

thanks James

You lost me here.

go get always pulls from master though ?

Where's here? O can try to provide more detail if you let me know what you're not following. If you go into each repo that's not working and checkout master, "go get -u" will work again.

Yes, "go get" clones the master branch if there is no local copy, and runs `git pull --ff-only` if the repo exists and the -u flag is provided (as you see in the log).

 

[Joe Blue]

thanks again.

your explanation about go get helped. 

SO i looked at the offending repo. Its not my repo, just someones on github

 github.com/pkg/sftp

What i cant work out is WHY this repo outputs weird git messages, and others dont.

Its not blocking me working, but i am just wanting to know. I am OC (Obsessive Compulsive) i guess :)

Maybe i shoudl just move on, but if you or others know why that repo does what it does would be great to understand.

Your *local* copy is in detached head state. I.e. you manually or some
vendoring script checked out something else than master at head. To fix
it you need to checkout master as said.

Others (your local copies) were not touched.

Get a book on git, e.g. "Git Essentials" ISBN 978-1-78528-790-9 or some
other out of 20+ written.

You will - just read a decent book bedtime.

This is NOT the offending repo, github.com/kr/fs is.

Do 'git checkout master' here
then 'git pull --ff-only'

thanks,

it was a dependency of the repo. Makes sense.

thanks.
