[labours] overflow encountered in ulong_scalars

[senden9]

Hi!

I tried hercules on a quite big private repository of our company. It seems that something in labours overflows. The repository use LFS if that matters.

CLI Output

$ ./hercules.linux_amd64 git@github.com:ORG/REPONAME.git repo-cache
[...]

$ ./hercules.linux_amd64 --burndown --granularity 2 --sampling 2 --pb repo-cache/ > baukasten_burndown.pb

$ ls -lh baukasten_burndown.pb

$ cat baukasten_burndown.pb | labours -f pb -m burndown-project

During handling of the above exception, another exception occurred:

Thanks for testing.

Is it possible to send me the YAML file (no --pb) to the email from my GitHub profile? There should be nothing private inside except the repo name, which you can edit by hand.

The current workaround is obviously to increase granularity and sampling until it stops to overflow.

Thanks! Mail is out.

With labours -m burndown-project --resample M < baukasten_burndown.yaml it is working without a problem.
