PHP Bug Type: XSLT related
Bug description: Memory leak using registerPHPFunctions and XSLT Variable as
function parameter
Description:
------------
Using registerPHPFunctions and calling a PHP function from XSL with
first parameter an XSL Variable (instead of node, node-text, etc.)
produces a memory leak.
Also "memory_limit" directive in php.ini is ignored.
Reproduce code:
---------------
<?php
// XML Contents
$sXML = <<< EOD
<?xml version="1.0" encoding="UTF-8"?>
<root>root node</root>
EOD;
$domXML = new DOMDocument();
$domXML->loadXML($sXML);
// XSL Contents
$sXSL = <<< EOD
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:php="http://php.net/xsl">
<xsl:template match="/">
<xsl:variable name="variable"> text </xsl:variable>
<xsl:value-of select="php:functionString('trim', \$variable)" />
</xsl:template>
</xsl:stylesheet>
EOD;
$domXSL = new DOMDocument();
$domXSL->loadXML($sXSL);
// XSLT Processor
$xsltProcessor = new XSLTProcessor();
$xsltProcessor->registerPHPFunctions();
$xsltProcessor->importStyleSheet($domXSL);
while (true) {
$xsltProcessor->transformToDoc($domXML);
}
Expected result:
----------------
Nothing.
Actual result:
--------------
All server available memory is used.
