Hi Steve and friends,

I've been getting a new fun set up errors the last couple of times I've tried to update the DB from the remote WURFL XML source. Here's the output:

Any ideas? Could this be fallout from a too-much-memory-being-used problem? It's not obvious what's happening from the errors - seems to me like it's trying to parse an empty file or something.

Hmmm, this is strange, especially because it shows that it loaded 14221 devices. Normally it would throw an exception if it could not parse the document at all. I'll see if something has been changed in the structure of the WURFL file.

Hi Steve,

Yeah I thought it was strange (but nice) that it updated the DB properly despite the errors. I just verified that the zip & xml downloaded by Tera-WURFL and the zip & xml available on sourceforge are identical so it's not a file corruption issue.

Crummy, turns out the update wasn't complete after all. Now I'm trying to find the last compatible WURFL file with tera-wurfl 2.1.4. Help?

Edit: I just reverted to the one from March 6th and had similar errors - and that one worked previously. I'm reverting the new web browsers patch and seeing if that makes a difference.

Are you using 2.1.4 from GitHub or the Tera-WURFL.com site? I would recommend grabbing the copy from https://github.com/kamermans/Tera-WURFL .

I believe it's 2.1.4 from the .com.

Reverting everything back to the previously functioning state is still giving the same errors. It's times like these...

Maybe PHP or SimpleXML or LibXML was updated. I would try the GitHub version which uses XMLReader instead of SimpleXML.

I had issues last time with XMLReader running out of memory so I had to revert to SimpleXML. I hope my host didn't make changes without notifying his clients.

Hi Marc, is there any way that you could run this script on the server that's giving you trouble? I'm trying to determine if a certain PHP version or extension is responsible for the problem.

Code: Select all

<pre>
<?php
echo "PHP ".phpversion()."\n\n";
$exts = array('xml', 'libxml', 'SimpleXML', 'XMLReader', 'mysql', 'MySQLi');
foreach($exts as $extname){
   try{
      $ext = new ReflectionExtension($extname);
      echo $ext->info();
   }catch(Exception $e){
      echo "ERROR: Extension $extname is not available\n\n";
   }
}
?>
</pre>
