Julia: LibGit2 push() has no effect

Created on 22 Feb 2017 · 20Comments · Source: JuliaLang/julia

I can't seem to push on 0.5 nor 0.6. Everything up to the push works fine.

I've also tried manually passing the remote url and setting force=true but they both return 0 and do nothing.

Reproducing:

libgit2 needs docs

The behaviour of CLI git is determined by the push.default config option. If we're going to change behaviour, I would prefer that we follow that.

Do you have GitHub 2FA set up, and have you confirmed that origin is a valid remote name in the cloned repo?

ararslan on 22 Feb 2017

I do not have 2FA on my GitHub account, and origin is a valid remote. Pushing from the command line after ending the Julia session works fine, so I know that the commit is definitely not an issue.

christopher-dG on 22 Feb 2017

Welp, I'm out of ideas then. I'm inclined to call this a bug.

ararslan on 22 Feb 2017

I'm having the exact same problem, not 2FA, push exits with a 0, push works from the command line. I thought I was just being an idiot so it's good to see it's not just me.

bramtayl on 22 Feb 2017

Apparently you need to manually specify at least 1 refspec, e.g.

LibGit2.push(repo, refspecs=["refs/heads/master"])

will push the master branch.

This whole interface probably needs redesigning as part of #19839, but in the meantime we should at least document this.

simonbyrne on 13 Mar 2017

I'm not familiar with code, but couldn't making refspecs=["refs/heads/master"] be the default be at least a short term fix?

bramtayl on 13 Mar 2017

I think a better solution would be for it to default to the current branch. Thoughts? I can make a PR for that + documentation.

That's a good idea. Is there a simple way to pass that value somewhere and have it do the work of figuring out how to behave, or do I need to do that myself?

christopher-dG on 13 Mar 2017

I don't think so, unfortunately (or at least, I couldn't find it).

simonbyrne on 13 Mar 2017

Oh well, I'll see what I can come up with.

christopher-dG on 13 Mar 2017

I think I can fix this tonight or at least make it more convenient.

Did https://github.com/JuliaLang/julia/pull/21227 fix this?

kshyatt on 31 Mar 2017

You can add information about the push refspecs in two other ways: by setting
an option in the repository's GitConfig (with push.default as the key) or
by calling add_push!. Otherwise you will need to explicitly specify
a push refspec in the call to push for it to have any effect, like so:
LibGit2.push(repo, refspecs=["refs/heads/master"]).

So as I understand it, I should be able to write LibGit2.push(repo) if push.default is set, but this is not working for me. I'm on the latest master as of this morning.

Afterwards, I tried using the add_push! method which worked.

Am I doing the first method incorrectly?

christopher-dG on 3 Apr 2017

Well, I'm glad my code works...

You might try setting a GitConfig variable push.default for the GitRepo itself?

No luck 😞

christopher-dG on 3 Apr 2017

Weird. I'll see if I can figure this out but if you want to open a PR to fix the docs go ahead.

kshyatt on 3 Apr 2017

Also, do you think this has been resolved sufficiently to close?

kshyatt on 4 Apr 2017

Definitely, any further discussion on how to make it better/more user friendly is unrelated to my 'this doesn't work!!!!' complaint :smile:

christopher-dG on 4 Apr 2017

Great, glad I managed to help.
