Error: "cannot re-use a name that is still in use"

I'm using

_, err := client.InstallOrUpgradeChart(ctx, &helmclient.ChartSpec{
    ReleaseName:     chart.releaseName,
    Namespace:       chart.namespace,
    Version:         chart.version,
    ChartName:       chart.chartName,
})

to install or upgrade a chart to a new version, but am getting this error: "cannot re-use a name that is still in use"

I thought this function would upgrade the chart if the release already exists. Is there some other function or parameter that I should be using to make it upgrade if there's a newer version and the release already exists?

Okay I think I found the issue:

go-helm-client/client.go

Line 784 in 43db5e2

if r.Name == spec.ReleaseName && r.Namespace == spec.Namespace {

If Namespace is not set in ChartSpec to default to the "default" namespace, this equality will fail. I think we need to update this function to account for that.

The workaround is to always explicitly set Namespace in ChartSpec.

Actually, this doesn't work 100% of the time since sometimes r.Namespace is "default" and sometimes it's "". I think it might depend on how the chart was installed.
