tree: accept null ids in existing trees when updating#4727
Merged
Conversation
When we add entries to a treebuilder we validate them. But we validate even those that we're adding because they exist in the base tree. This disables using the normal mechanisms on these trees, even to fix them. Keep track of whether the entry we're appending comes from an existing tree and bypass the name and id validation if it's from existing data.

This would be one for backporting into a maintenance release. |

I was misreading this commit the whole time, as I first misinterpreted the from_tree parameter to mean the exact opposite thing. I think this would be a bit easier to reason about if this was instead called validate, with the value passed by callers being the inverse from what it is now.

Could you please add a small comment detailing what is so special about the tree 396c7f1? It's rather hard to reason about this test otherwise :)
