Description

In https://github.com/open-component-model/open-component-model/blob/d134f52155dcc1f25829cd1fff01cac5bd7aa5a6/bindings/go/helm/repository/resource/resource_repository.go#L118 we added a helper method that walks the downloaded dir and tars a helm chart and prov file.

This should actually be doable with filesystem.GetBlobFromPath (https://github.com/open-component-model/open-component-model/blob/1062fdf73fd4724133ca0fe0c81b5a9e58ff1f39/bindings/go/blob/filesystem/blob_from_path.go#L52)

After testing for several hours, we decided to do this at a later stage.
The problem seems to be that GetBlobFromPath works async with Pipes, but our tarReader that later accesses the blob, cannot handle this correctly.

Done Criteria

• Provide a way to sync-read from GetBlobFromPath or fix the tar-reader to be able to handle the direct blob
• Code has been reviewed by other team members
• Analysis of existing tests (Unit and Integration)
• Unit Tests created for new code or existing Unit Tests updated
• Integration Test Suite updated (includes deletion of existing unnecessary Integration Test and/or creation of new ones if required)
• Enduser Documentation updated (if applicable)
• Internal technical Documentation created/updated (if applicable)
• Successful demonstration in Review
