Diff-cover becomes un-responsive when comparing with upstream/master

[vibhore-gupta]

Thanks for the wonderful tool. Although, i have a situation to report here.

When i use --compare-branch flag and provides an upstream branch like upstream/master, diff-cover becomes un-responsive.

I am using a dotnet Core Solution with over 200 projects in it. Full scenario with detailed steps are as following:

1. Developer creates a developer fork from the upstream repo like(user/project).
2. Creates a local branch in the developer fork. Make the code changes and runs the coverage tool (dotcover in this case)
3. Feed the coverage file in Cobertura format to diff-cover and compare it with the upstream/master.(Before running this , it was made sure the local branch is rebased with upstream/master)
   diff-cover {path-to-the-cobertura-coverage-file} --fail-under=20 --compare-branch=upstream/master

Diff-cover freezes and doesn't respond.

Please suggest if there is anything wrong with my steps and is there a fix that i can do to make this run. Thanks

Hmm, I dont think there is anything wrong with your steps. I have not heard of diff cover working on a massive monorepo before. Especially not one cloned locally.

I dont have a great answer for you but I suspect diff cover is doing something inefficient but I dont have a great sense on what specifically would be the issue
