helm-diff return no diff when helm chart status is failed

[tanguofu]

when a installed helm chart update failed，helm diff cannot show diffs

[tanguofu]

any hlepers here？

Facing the same issue. You can see the problem if you do helm get manifest <your release>. More likely your recent changes are there even though the status is failed, therefore the subsequent helm-diff doesn't see any diff.

This behaviour started being annoying for us. Don't know if it's even possible to do anything with it, because it's how Helm works - it writes all resource information in the secret even when the installation fails.

@tanguofu @andrewnazarov I verified that --three-way-merge added via #304 fixes this issue. Closing as resolved. Probably it will be released as part of 3.3.0. In the meantime, please build helm-diff from the latest master if you're eager to test it early. Thanks!
