GitVersion package

GitVersion.Tool

GitVersion version

6.0.2

Operating system

Linux

What are you seeing?

This is for

      git status
      dotnet gitversion /version
      dotnet gitversion $(Build.SourcesDirectory) /output buildserver /nofetch

on Azure DevOps pipelines (git status only added for testing and because some old issue mentioned that the index might be the culprit).

I am seeing a "pause" in the log - and it always happens for the current PRs branch (pull/2271/merge) End and the Begin of the actual branch I created comparing to develop (GitFlow). Below are two runs, as you can see it seems to wait for 3 minutes for no reason at all.

This also already happened for 6.0.0, I was testing 6.0.2 to see if there would be a difference.

I scrolled all "Took: " and I found one sore thumb:

2024-08-13T07:39:19.2643763Z INFO [24-08-13 7:39:19:26] -< End: Fetching the base versions for version calculation... (Took: 197,524.02ms) >-

However, that would never add up because no other Took: ever exceeded low 100s of ms, most of them were single digit.

INFO [24-08-13 7:36:00:97] -< Begin: Normalizing git directory for branch 'refs/pull/2271/merge' >-
  INFO [24-08-13 7:36:01:00] One remote found (origin -> 'https://someazdourlredacted/myrepo').
  INFO [24-08-13 7:36:01:00] Skipping fetching, if GitVersion does not calculate your version as expected you might need to allow fetching or use dynamic repositories
  INFO [24-08-13 7:36:01:01] Creating local branch pull/2271/merge pointing at d4d958b
and then a lot more Creating local branch

What is expected?

Of couse not seeing the pause.

Steps to Reproduce

Not sure if that reproduces outside of our project.

Output log or link to your CI build (if appropriate).

I think it's a logging issue, we need to add more logs for the Finding merge base between

It'd be really nice to know where those three minutes went (maybe it is some out of whack branch or something)

I'm also having this issue as well, it's very strange.
