Query files using OnDirectory fails with exception

[marcus]

I'm using RavenDB 3.0.3460-Unstable with this code

using (var session = _filesStore.OpenAsyncSession())

{

var files = await session.Query().OnDirectory("/images").ToListAsync();

};

this fails with this exception http://bit.ly/1qYFVID

The following code should work:

using (var session = _filesStore.OpenAsyncSession())

{

var files = await session.Query().OnDirectory("images").ToListAsync();

};

For me, it still throws an exception. The query looks like this /fs/BrickPile/search/?query=(__directory:/images%20AND%20-__directory:/images/*)%20AND&start=0&pageSize=1024 but if I alter the query to /fs/BrickPile/search/?query=(__directory:/images%20AND%20-__directory:/images/*) and put it into the browser it returns the correct data.

This is the actual error message when I try the query directly in the browser using the first query: /fs/BrickPile/search/?query=(__directory:/images%20AND%20-__directory:/images/*)%20AND&start=0&pageSize=1024

Can anyone verify if this works, because it doesn't for me?

[Federico Lois]

I hace already fixed it in my branch as soon as Oren merge it in the truck it will be available in the next unstable.

Ok, fantastic!

[Federico Lois]

Unstable Build #3465 already has the fix for OnDirectory. 

[marcus]

Nice, that solved the problem. Another thing, if I run session.Query().OnDirectory(folder).ToListAsync(); and folder is an empty string I get all files recursive even though recursive is false by default, is this correct?

[Federico Lois]

No. Is not correct. Should return only the root. Will fix that one tomorrow first time in the morning.

Marcus,

I have been working on this: http://issues.hibernatingrhinos.com/issue/RavenDB-2673 but it is a bit more involved than expected. Will get you back as soon as I have a solution for it.
