FSProvider: dependency on hierarchical paths?

[joaomoreno]

Testing #35009

Maybe the Explorer has a requirement on hierarchical resources having hierarchical URIs...

[jrieken]

No clue, @isidorn @bpasero What defined the structure of the explorer model? The hierarchical stat model, or uri-path-math, or both?

[isidorn]

Getting children in the explorer is done by resolving the file here
Also getting the parent we usualy do stat.parent and try not to do any path smartness.
AFAIK we have no dependency on hierarchical paths, though there are probably some assumptions regarding the hierarchy hidden somewhere.

@jrieken didn't you say at one point that we expect extension authors to return URIs that follow a disk scheme, e.g. there is hierarchy reflected in the URI. In other words, we would not expect URIs such as: scheme://myserver.something/?resolve=something

Anyway, we do expect a hierarchy in all our calls to isParent where we want to find out if one path is a parent of another. So yes, this expectation drags through our system....

Well, yes and "hello, here comes reality" maybe no. One problem was that we were not able to get @joaomoreno's stats to show in the explorer and we were clueless why... So one guess was that the explorer depends on hierarchal paths. It's not clear if all providers can full-fill the requirement of such paths but it is valuable to know that we will have a hard time without them

In my example, my URIs didn't represent the hierarchy the actual underlying model had. A parent's URI was not a prefix to all its children's URIs.

Closing as question, the answer seems to be "Yes, we depend on hierarchical uris..."
