Bug with external Alfresco WebDAV (RFC-compliant) server #16471

solracsf · 2019-07-19T13:20:46Z

This is a weird bug.

I've configured a test setup including both Alfresco - they claim a RFC-compliant DAV implementation: https://docs.alfresco.com/6.0/concepts/troubleshoot-webdav.html - and Nextcloud on the same server using docker (official NC docker image, using SQLite) on Ubuntu 18.04. Connection between both is well established (there is no encryption/TLS involved on the connection).

On the initial WebDAV setup (accessing Alfresco files trough WebDAV on Nextcloud) I've uploaded two files and checked if they were well uploaded on Alfresco. No problem.

But, if i upload any new file or create any new folder trough Nextcloud, i can only see that new file/folder, and not previously uploaded files or existent folders. Files or folders are well visible on Alfresco, previous and new ones. And it reproduces any time I upload any new file OR create any new folder trough Nextcloud interface on the DAV folder.

Only this new content is visible on Nextcloud interface (or mobile apps), not previous content on the DAV (Alfresco) server.

But if i try to re-upload an existent file, NC claims it already exists and if it should be rewrite, even if the file is not visible.

The only lines write on the log files are these:

[PHP] Error: Undefined variable: response at /var/www/html/lib/private/Files/Storage/DAV.php#283
[PHP] Error: Undefined offset: 1 at /var/www/html/3rdparty/sabre/dav/lib/DAV/Xml/Element/Response.php#237
[PHP] Error: Undefined index: {DAV:}status at /var/www/html/3rdparty/sabre/dav/lib/DAV/Xml/Element/Response.php#236

If any further info is needed, I'll be glad to provide it.

The text was updated successfully, but these errors were encountered:

Mind to add the raw response from alfresco? Check #15363 (Curl Logs)

There is a gap in the code 🤔

server/lib/private/Files/Storage/DAV.php

Lines 250 to 284 in 631ae17

    
           protected function propfind($path) { 
        
           	$path = $this->cleanPath($path); 
        
           	$cachedResponse = $this->statCache->get($path); 
        
           	// we either don't know it, or we know it exists but need more details 
        
           	if (is_null($cachedResponse) || $cachedResponse === true) { 
        
           		$this->init(); 
        
           		try { 
        
           			$response = $this->client->propFind(

           			); 
        
           			$this->statCache->set($path, $response); 
        
           		} catch (ClientHttpException $e) { 
        
           			if ($e->getHttpStatus() === 404) { 
        
           				$this->statCache->clear($path . '/'); 
        
           				$this->statCache->set($path, false); 
        
           				return false; 
        
           			} 
        
           			$this->convertException($e, $path); 
        
           		} catch (\Exception $e) { 
        
           			$this->convertException($e, $path); 
        
           		} 
        
           	} else { 
        
           		$response = $cachedResponse; 
        
           	} 
        
           	return $response; 
        
           }

We have no cached response and call propfind. The response is faulty, a expection is thrown, catched and passed to convertException but there is no code to handle this kind of failure. Code reaches the last return statment without initializing $response.

server/lib/private/Files/Storage/DAV.php

Line 834 in 631ae17

    
           \OC::$server->getLogger()->logException($e, ['app' => 'files_external', 'level' => ILogger::DEBUG]);

Could you change the logging level to debug? The exception is only logged with this level.

Hi @kesselb please find Debug log here attached.

I can also provide a test server if needed.

I've also tried the patch at #15363 (comment) and no help in this specific case.

kesselb · 2019-07-23T10:23:34Z

Thanks 👍

kesselb · 2019-07-23T13:43:20Z

OK. The above response is fine. I extracte the "parse response" code into a single script: https://github.com/kesselb/nextcloud-dav

I think we need a different response from alfresco. I assume the external share is called Alfresco and resolves to http://ip_here/alfresco/webdav/Webdav. Mind to propfind http://ip_here/alfresco/webdav/Webdav/Nextcloud.mp4 and share the response?

It might be easier to add some debug code to nextcloud but don't use this on production and remove it after you reproduced the problem / triggered the exception.

Thanks 👍

<D:prop></D:prop> is the faulty part.

Correct response (with 1+ elements in props)

Faulty response (with no elements in props)

Just one more hint; if a file is MOVED into the "Alfresco" folder (WebDAV root) and then I go into that folder, it is empty (but if i just upload or COPY a new file into it, i can see that file).

For now, we've mounted our Alfresco trough davfs2 on Ubuntu and then using External Storage > Local on NC pointing to /mnt/alfresco.

in V17.0 this still fails:

There is a note in their website that states:

Moving a file or folder using WebDAV on an Ubuntu client causes loss of metadata and creates a new node reference

There is a known issue where Ubuntu creates a new nodeRef when you move a file or a folder in WebDAV, because it uses PUT and DELETE methods instead of a MOVE method. As a result, the nodeRef for the file or folder changes and any associated metadata is lost. This issue applies to all versions of Ubuntu, but does not occur when using a Windows client.

Can this be related (and fixed)?

With newer Nextcloud versions, a new exception is thrown, maybe it helps solving this:

Is this Issue still valid in NC21.0.2? If not, please close this issue. Thanks! :)
