What is expected?

should not throw exception and should work as expected ^^

Steps to Reproduce

dotnet tool install GitVersion.Tool --version 6.* --create-manifest-if-needed
dotnet tool restore
dotnet dotnet-gitversion /config $ConfigFilePath /output buildserver

RepositoryFixture Test

No response

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

We need a Git Repository to check with, please provide some steps to reproduce as the exception is not enough for investigation

[ulluoink]

i am of course not allowed to share oine of our repositories.

it happens everytime we execute the given commands (see above) in each repository we use.

it happens since yesterday when 6.0.3 was published and since the step is using 6.0.3

what more info do you need?

As you can see from the stack trace, the problem occurs in LibGit2Sharp. The stack trace is:

1. EncodingMarshaler.cs:120
2. Signature.cs:22
3. Proxy.cs:289

Which indicates that there's a commit with an author name so large it can't be unmarshalled from its native pointer into a C# System.String. I would consider this a bug in LibGit2Sharp, as it shouldn't crash on anything that doesn't crash libgit2 itself, but I can see why such a large author name isn't expected and therefore not handled more gracefully.

@ulluoink, I would recommend that you go through the commits and inspect what author name may be the culprit here. Perhaps you can ignore the bad commits so GitVersion doesn't try to instantiate them through LibGit2Sharp, or amend them with Git itself so they become instantiable. Either way, this is a problem outside the scope of GitVersion and either has to be fixed in the repository itself or in LibGit2Sharp.
