Trying to create an empty container with Slug .scad

[rimmartin]

Hi,

cloned this project in the last hour and stood it up serving bin/solid-test for a local developer pod.
added a folder under public called scad. Then with the following code tried to make an empty container with Slug: '.scad'. No errors but when I look with browser at https://roger.localhost:8443/public/scad/ I see an empty container '7fed9310',

        solid.auth.fetch('https://roger.localhost:8443/public/scad/', {
           method: 'POST', 
           headers:{
            'Content-Type': 'text/turtle',
	    'Link': '<http://www.w3.org/ns/ldp#BasicContainer>; rel="type"',
            'Slug':  '.scad'
	   }
           }).then((res) => {return res;})
        .then((response) => {callback(null);})
        .catch(error => callback('Error: '+JSON.stringify(error)));

when I curl for '7fed9310'

 curl -k --cert ../roger-g74s.cert --key ../roger-g74s.key -G https://roger.localhost:8443/public/scad/7fed9310
Can't find file requested: data/roger.localhost/public/scad/7fed9310

it's not there. Nor '.scad' either can be found.

@rimmartin Thanks for the report. For us to determine the best way to respond to this, can you let me know if the following is an accurate summary of what you're reporting?

• You're looking to use the Slug header to inform the URI of the created container resource
• A resource is created, but not at the URI (.scad) that you specified in the Slug header
• when you try to access that created resource via curl, you can't find it

@justinwb , yes

have https://roger.localhost:8443/public/scad/
check and it exists and is pristine, no other operation or child has been attempted. Then with the Slug I try to put an empty '.scad' container in it.

The results wasn't the same any try where I blew away everything and came back with the server, user and run api again.
I made more attempts and put logs in the server code; it looks like I'm hitting an internal pod meta folder name; there looks like a uuid.v1() applied to make mine unique to get around it but this is not working; https://github.com/solid/node-solid-server/blob/master/lib/ldp.js#L534

${uuid.v1().split('-')[0]}-${filename}`))

in the recursive ensureNotExists function

Right, so, we have Slug in the spec, but it seems like the support for it is poor. We need to look into that.

[rimmartin]

A Slug: '.git' works fine Or any regular folder name. It is only if the name is the same with a period prefixed .scad into scad/

This would appear to be a pretty straightforward bug.

The Slug header comes from the ldp specification, which you can checkout here - https://www.w3.org/TR/ldp/
