git push fails and throws three errors

[Laurin Brinkmann]

We are using Team Foundation Server 2013 Update 3 as our Git Server and SourceTree to manage our Repositories with Git Flow.

Two of our (14) developers cannot push changes from their local /develop-branch to origin. Both get this error log:

Now I've done some research and testing and this is what I've found out:

• Yesterday only one of the two devs could not push. Today the second dev could not push anymore (He did push yesterday though.)
• Both can still push to other remote branches, like shared-feature-branches. So far it is only happing when they try to push to origin/develop.
• They can still push to origin/develop using Git via Visual Studio 2013.
• I could not find any reference to the error message: 'fatal: protocol error: bad line length character: ent-'. There were different parameters, not 'ent-'.
• I have tried to extend the [http] postBuffer

Do you have any idea how to solve this problem?

I am glad this post did help you. Neither did I find a better solution yet. But today I have learned that after pushing (/resolving the problem) from Visual Studio, you are able to push from SourceTree again. Strangely, it seems to be a temporary issue.

I had this exact problem and never did find a solution. Except, until I ran across your question and saw that while you couldn't push from SourceTree (I couldn't push from console either), you *could* push from Visual Studio - which I hadn't thought to try. I tried, and it worked! Thank you.

I think your problem is with TFS doing something in a non-standard way, try asking on a MS forum.

Another thing that might be worth looking at is the core.autocrlf setting in the people's .gitconfig files. If the one/two people have a different setting than the rest, this might be connected. (As far as I know, this is the only client-side setting that could be relevant.)
