<p>I've a problem with <code>schema_mysql.inc,v 1.13.2.2 2008/02/16</code>, from the 5.x-1.1 release. There in function <code>schema_mysql_inspect</code> can be found:</p>
<div class="codeblock">
<pre><span style="color: #000000"><span style="color: #0000BB"><?php<br> </span><span style="color: #FF8000">// Ignore tables not in Drupal's schema.<br> </span><span style="color: #007700">if (!isset(</span><span style="color: #0000BB">$schema</span><span style="color: #007700">[</span><span style="color: #0000BB">$r</span><span style="color: #007700">[</span><span style="color: #DD0000">'TABLE_NAME'</span><span style="color: #007700">]])) {<br> continue;<br> }<br></span><span style="color: #0000BB">?></span></span></pre></div>
<p>But this is no good. I try to port the spam module to schema and I could'nt get proper schema output with the schema inspect:</p>
<blockquote><p>warning: Invalid argument supplied for foreach() in /home/milian/projects/drupal-5.7/modules/schema/schema.module on line 25.</p></blockquote>
<p>This is because of the above mentioned part. Output here is for example:</p>
<div class="codeblock">
<pre><span style="color: #000000"><span style="color: #0000BB"><?php<br>$schema</span><span style="color: #007700">[</span><span style="color: #DD0000">'spam_filters_errors'</span><span style="color: #007700">] = array(<br> </span><span style="color: #DD0000">'fields' </span><span style="color: #007700">=> array(<br> ),<br> </span><span style="color: #DD0000">'primary key' </span><span style="color: #007700">=> array(</span><span style="color: #DD0000">'bid'</span><span style="color: #007700">),<br> </span><span style="color: #DD0000">'unique keys' </span><span style="color: #007700">=> array(<br> </span><span style="color: #DD0000">'content_hash' </span><span style="color: #007700">=> array(</span><span style="color: #DD0000">'content_hash'</span><span style="color: #007700">),<br> </span><span style="color: #DD0000">'content_id' </span><span style="color: #007700">=> array(</span><span style="color: #DD0000">'content_id'</span><span style="color: #007700">, </span><span style="color: #DD0000">'content_type'</span><span style="color: #007700">)),<br> </span><span style="color: #DD0000">'indexes' </span><span style="color: #007700">=> array(<br> </span><span style="color: #DD0000">'content_hash_2' </span><span style="color: #007700">=> array(</span><span style="color: #DD0000">'content_hash'</span><span style="color: #007700">),<br> </span><span style="color: #DD0000">'content_type' </span><span style="color: #007700">=> array(</span><span style="color: #DD0000">'content_type'</span><span style="color: #007700">),<br> </span><span style="color: #DD0000">'hostname' </span><span style="color: #007700">=> array(</span><span style="color: #DD0000">'hostname'</span><span style="color: #007700">),<br> </span><span style="color: #DD0000">'timestamp' </span><span style="color: #007700">=> array(</span><span style="color: #DD0000">'timestamp'</span><span style="color: #007700">)),<br>);<br></span><span style="color: #0000BB">?></span></span></pre></div>
<p>The fields are missing obviously. If I remove the above mentioned code from <code>schema_mysql.inc</code> it works properly! But the comment tells me, that there seem to be other issues involved.</p>
