In my experience, working with a Git repository hosted by Gitlab, Github, or Gitorious has generally been issue free and enjoyable. Recently, however, three members of my team ran across the same cryptic RPC error when trying to push changes to a remote repository on Gitlab:
error: RPC failed; result=22, HTTP code = 411
In two cases, developers were trying to push new framework libraries (they were moderately sized, 2-9 MB). In the third case, a designer was trying to push a large batch of image assets. In all cases, the problem was caused by using the HTTPS protocol with a server configuration that disallowed individual files larger than 1 MB.
After some basic investigation (thanks Stack Overflow!), we found that using the SSH protocol with Git solved the problem. This type of issue could trip up a new user of Git, so I am going to use this post to briefly describe the problem and summarize the pros/cons of using HTTPS vs. SSH protocols to talk to remote repositories.
