Hi there,
Since I contributed updated formulae for Go (Homebrew/homebrew-core#9304 and Homebrew/homebrew-core#9305), various brew commands (including, sadly, brew doctor) fail with Error: stack level too deep. I've run brew update twice, I've tried re-running the installation script. It seems that the problem occurs when homebrew-core is not checked out on the master branch:

$ brew doctor
Error: stack level too deep

$ cd /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core
$ git status
On branch go-1.7.5
Your branch is up-to-date with 'tsuna/go-1.7.5'.
nothing to commit, working tree clean
$ git checkout master
Switched to branch 'master'
Your branch is up-to-date with 'origin/master'.

This fixes it. I'm not sure why being on that branch (the state of which you can find here: https://github.com/tsuna/homebrew-core/tree/go-1.7.5) would cause this stack overflow error. How can I troubleshoot this further?

Not that I care much anyway, since I don't intend to stay on that branch as the changes have merged upstream anyway, but I found this error very confusing and not easy to root cause, and I'm puzzled as to why this would make various brew commands fail like that.

HOMEBREW_VERSION: >1.1.0 (no git repository)

This is concerning. Make sure you've committed everything to all your branches and run brew update-reset.

I don't have any local changes that haven't merged upstream, so I ran brew update-reset and after that when I checkout the branch go-1.7.5 in homebrew-core I still have the same error when running brew outdated --debug.

What about the master branch? What's the diff on go-1.7.5?

As I mentioned earlier, it works fine on the master branch. I also provided a link above to the contents of my go-1.7.5 branch, which was automagically created by brew bump-formula-pr when sending the PR Homebrew/homebrew-core#9304. I had forgotten about it and stayed on that branch since then, which recently started to cause this weird error. It took me quite some time to realize that I was on that branch and that switching back to master would fix the problem, so I decided to file this issue to get some advice on why this could be happening, as it looked fishy and could maybe help someone else down the road if they run into the same situation.

This is still pretty weird and concerning. Have you always seen no git repository here?

What does brew tap output (or brew tap --debug if it throws an exception)? Thanks!

@MikeMcQuaid I've just experienced the same issue, most probably due to having contributed the formula bento4 a few days ago.

I ran brew update-reset and it solved the problem.

My question is: is that a required step after contributing a formula (i.e. something that contributors need to do), and if so, couldn't this be somewhat automated? Or is it just a bug?

Here's my info before running brew update-reset:

$ brew upgrade
Error: stack level too deep

$ brew doctor
Please note that these warnings are just used to help the Homebrew maintainers

working fine: please don't worry and just ignore them. Thanks!

It sounds like a bug. If you can create a reproducible set of commands after running brew update-reset: please open a new issue and we'll look at fixing it, thanks.

I'm not sure how to recreate / reproduce it without actually contributing or updating a formula. But I'll keep this in mind next time opening a PR.
