Thanks, Would you mind re-basing this on master to pick up the build fixes? Also, update the CHANGELOG.md with this: |

Looking at the documentation
The node should only return a value of Primary. Any other value indicates that the node is part of a nonoperational component. This occurs in cases of multiple membership changes that result in a loss of quorum or in cases of split-brain situations.
I think we should change this block to be an else. Anything that doesn't match "Primary" should return 0.

CC @rtreffer, what do you think?

It looks like the rebase you did was not fast-forward. This caused all of the upstream changes to be added to this PR. I would recommend resetting your fork and using "For and Branch Workflow" to avoid funky git history. |
"strings" needs to be added to the import list. |
Done. |
