Can you go into the details of what breaks without this and why is the lazy parent not enough?

getParent used to just directly get it in https://github.com/nextcloud/server/pull/38150/files#diff-edc136e5646ea4171607db53b38833e8f6caaacc64874a0a850aa4444f0a56edL303-R309 but now always makes use of the file info which is not available for a nonexisting file.

Then wouldn’t the right fix be to check for fileinfo presence before calling getParentId on it and fallback on previous behavior if fileInfo is not there? I’m afraid there might be other side effects we missed.

Yeah might be indeed a good idea, will check that

Pushed a more generic approach but still passing the parent to the NonExistingFile to avoid an extra queries in that case.

doesn't it just move the query to the constructor call here?
As is it always does the "get parent" query even when getParentId isn't called, without this it only does the query when getParentId is called

Or get? But a word is missing there I think.

Yeah let me maybe drop that then instead and just rely on the manual get in getParent instead |

Summary
Fixes calls to getParent after #38150 when calling on NonExistingFile instances, e.g. within a BeforeNodeRenamedEvent.
Found in failing tests for moving files in text which has special handling. CI is passing with this branch again: nextcloud/text#4779
