always getting empty ACES

Question

always getting empty ACES

courville opened this issue 2 years ago · 14 comments

Hi, thanks a lot for sardine that I am trying to integrate into my application (nova video player).
I need to check if I can read or write on a specific url and I am trying to use:

boolean canRead = (sardine.getAcl(url).getAces().get(0).getGranted().get(0) == "read");
boolean canWrite = (sardine.getAcl(url).getAces().get(0).getGranted().get(1) == "write");

Unfortunately sardine.getAcl(url).getAces() is always empty and acl.getOwner(), acl.getGroup() are always null.
I used this following simple code (that works with sardine.list(url)):

package org.courville.sardinetest;

import com.github.sardine.*;

import java.io.IOException;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        // arguments are: user password url
        Sardine sardine = SardineFactory.begin();
        sardine.setCredentials(args[0], args[1]);
        String url = args[2];

        DavAcl acl;
        try {
            acl = sardine.getAcl(url);
            System.out.println("fromUri owner=" + acl.getOwner() + ", group=" + acl.getGroup());
            List<DavAce> aces = acl.getAces();
            boolean canRead = false;
            boolean canWrite = false;
            if (! aces.isEmpty()) {
                canRead = (aces.get(0).getGranted().get(0) == "read");
                canWrite = (aces.get(0).getGranted().get(1) == "write");
            } else {
                System.out.println("fromUri: aces empty for uri=" + url);
            }
            System.out.println("fromUri: uri=" + url + ", canWrite=" + canWrite + ", canRead=" + canRead);
        } catch (IOException e) {
            System.out.println("IOException in getAcl");
        }
        //List<DavResource> resources = sardine.list(httpUri.toString());
    }
}

which outputs:

fromUri owner=null, group=null
fromUri: aces empty for uri=https://redacted/file.txt
fromUri: uri=https://redacted/file.txt, canWrite=false, canRead=false

Is this normal or am I doing something wrong?
Thank you in advance for any hints that would help me progress.

The best thing would be to turn on logging for the http client stuff and take a look at the request/response stuff at the http level.

@lookfirst, sorry, I should have provided wire/header logs in the first place and not a sample code to reproduce, here you go:

It seems that server response is indeed empty.

Deleted my first response as I was quick to judge and didn't read the full log. My apologies.

Answer 4 · 2023-03-23T18:20:34.000Z

It looks like you're getting 404, file not found back from the server after authentication.

2023-03-23 15:17:19,666 [main] DEBUG org.apache.http.wire - http-outgoing-0 << "<D:status>HTTP/1.1 404 Not Found</D:status>[\n]"

Answer 5 · 2023-03-23T19:00:18.000Z

@lookfirst, thanks for the feedback. I checked the url and credentials and I can confirm that I can download the file from a browser.
I can also list the file with sardine.list(url) using the same program and everything works "as expected" (cf. below logs e.g. <lp1:getcontentlength>325129119</lp1:getcontentlength>). However as you spotted, it fails when doing sardine.getAcl(url) with 404 which to me is strange.

To be clear following code:

try {
            System.out.println("Let's try sardine.list(url)");
            List<DavResource> resources = sardine.list(url);
            System.out.println("Now let's try sardine.getAcl(url)");
            acl = sardine.getAcl(url);
} catch (IOException e) {
            System.out.println("IOException in getAcl");
}

Yields:

Let's try sardine.list(url)

Answer 6 · 2023-03-23T19:18:07.000Z

BTW I failed to say thanks for sardine! It has just been integrated in the open source Android nova video player https://github.com/nova-video-player/aos-AVP for webdav network share support: it is working great (just trying to get the canRead/canWrite wired in).

Answer 7 · 2023-03-23T20:17:26.000Z

I had an idea... try setting the depth:

2023-03-23 15:17:17,571 [main] DEBUG org.apache.http.headers - http-outgoing-0 >> Depth: 0

You can set it to some high number like 10 or something.

Answer 8 · 2023-03-23T20:51:55.000Z

Answer 9 · 2023-03-23T22:18:44.000Z

Ok, maybe too far, try depth: 1

=)

Answer 10 · 2023-03-24T08:55:22.000Z

OK:

http-outgoing-0 >> Depth: 0 yields: http-outgoing-0 << "<title>404 Not Found</title>
http-outgoing-0 >> Depth: 1 yields: http-outgoing-0 << "<title>404 Not Found</title>
http-outgoing-0 >> Depth: 2 yields: http-outgoing-0 << "<title>400 Bad Request</title>
http-outgoing-0 >> Depth: 3 yields: http-outgoing-0 << "<title>400 Bad Request</title>
http-outgoing-0 >> Depth: 10 yields: http-outgoing-0 << "<title>400 Bad Request</title>

Answer 11 · 2023-03-24T09:30:30.000Z

FYI I tried both on synology NAS and some other webdav server like koofr.net and same behavior.

Answer 12 · 2023-03-24T15:30:56.000Z

So the 400 bad request could be related to the DavDepthInfinity setting.

Now, what I'm thinking is that some sort of other parameter is missing from the request that the server is expecting here. What I'd do is spend some time reading the mod_webdav source code to see what happens when a PROPFIND comes in and what it expects. Looking to see where it returns 404 vs. 400 is another one.

Maybe also @gstein can help too (sorry to ping you buddy).

Answer 13 · 2023-03-30T19:33:16.000Z

Any hope on addressing the issue?

Answer 14 · 2023-03-30T23:44:52.000Z

What I'd do is spend some time reading the mod_webdav source code to see what happens when a PROPFIND comes in and what it expects. Looking to see where it returns 404 vs. 400 is another one.

That was my next suggestion. Have you done that?
