💛 - Coveralls

[ligangty]

Generally LGTM except a simple param hint.

@ligangty Do you know why the rpm-build checks were stuck? I see it also happened on your #361, not sure how to rebuild, it seems unable to merge.

[yma955]

@ligangty I tried to rerun, failed due to Coveralls 422 problem, unable to merge from my side.

[ligangty]

@yma955 that's weird. I've tried a PR #363 but it does not meet this issue. Can you rebase and have a try?

[yma955]

@ligangty pass after rebase, thanks!
