Description

I saw an issue while importing forums from PunBB 1.2.10 into bbPress. This problem exists in bbPress 2.5.15 and 2.6-RC-7.

Because PunBB 1.2.10 importer isn't included with the most recent version of bbPress (2.5.15, 2.6-RC-7), I had to create a custom importer, which seems to be working fine.

However, it always stuck on the same post. I managed to find a workaround, but in order to apply a fix I had to touch the core bbPress file /admin/includes/parser.php - and I'd like to get this issue resolved in bbPress 2.6 if possible.

Here's the topic content I'm trying to import:

Ac merentur natura te vel sem te aut ante lius eorum eum eos Quasi assum te ac platea.
Numero aut tui pede praecipue!

This is the error message:

It breaks on this line of code:

$this->Internal_UpdateParamsForMissingEndTag(@$token[BBCODE_STACK_TAG]);

Value of the $token[BBCODE_STACK_TAG] array item for this particular post is:

array (size=7)
  '_tag' => string '[b]' (length=3)
  '_endtag' => string '' (length=0)
  '_name' => string 'b' (length=1)
  '_hasend' => boolean false
  '_end' => boolean false
  '_default' => boolean false
  '_params' => 
    array (size=1)
      0 => 
        array (size=2)
          'key' => string '' (length=0)
          'value' => string '' (length=0)

I resolved the issue by making two changes to the parser.php file.

First, replaced the line 1485:

$this->Internal_UpdateParamsForMissingEndTag(@$token[BBCODE_STACK_TAG]);

with the following code:

@$token[BBCODE_STACK_TAG] = $this->Internal_UpdateParamsForMissingEndTag(@$token[BBCODE_STACK_TAG]);

And then, changed Internal_UpdateParamsForMissingEndTag function definition to this:

function Internal_UpdateParamsForMissingEndTag($params) {
switch ($this->tag_marker) {
case '[': $tail_marker = ']'; break;
case '<': $tail_marker = '>'; break;
case '{': $tail_marker = '}'; break;
case '(': $tail_marker = ')'; break;
default: $tail_marker = $this->tag_marker; break;
}
$params['_endtag'] = $this->tag_marker . '/' . $params['_name'] . $tail_marker;
return $params;
}

Notice that I removed the reference sign & in front of the $params parameter and added return $params at the end of the function definition.

Could you please apply the fix in the core file or provide a different solution?

Thank you.
