#23128 [Fbk->Opn]: PHP crashes when using <xsl:sort> in some cases

ID: 23128 User updated by: ed at avi dot ru Reported By: ed at avi dot ru -Status: Feedback +Status: Open Bug Type: XSLT related Operating System: Windows 98 PHP Version: 4.3.2RC1 New Comment: XML file (test.xml): <?xml version="1.0"?> <root> <node id="3" /> <node id="1" /> <node id="2" /> <node id="4" /> </root> XSL-template (test.xsl): <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:template match="/root"> <xsl:for-each select="node"> <xsl:sort select="@id" data-type="text" /> <xsl:value-of select="@id" /> </xsl:for-each> </xsl:template> </xsl:stylesheet> PHP script which causes the crash: <?PHP $xslt = xslt_create (); xslt_set_base ($xslt, sprintf ('file://%s/', dirname ($_SERVER['SCRIPT_FILENAME']))); print (xslt_process ($xslt, 'test.xml', 'test.xsl')); xslt_free ($xslt); ?> Previous Comments: ------------------------------------------------------------------------ [2003-04-23 03:59:22] sniper@php.net Please provide a short and self-contained example which causes the crash. ------------------------------------------------------------------------ [2003-04-10 09:35:28] ed at avi dot ru The problem remains. Òíå php doesn't crash now, but seems to hang or something like this. The page doesn't load, and the system becomes overloaded until the Apache process is killed (PHP runs as ISAPI module). ------------------------------------------------------------------------ [2003-04-09 16:49:09] sniper@php.net Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip ------------------------------------------------------------------------ [2003-04-09 06:55:03] ed at avi dot ru The realisation of sorting seems to be buggy in xslt extension. Let's suppose that we have the following xml: <?xml version="1.0"?> <root> <node id="1"></node> <node id="4"></node> <node id="2"></node> <node id="3"></node> </root> We're processing these data via xslt_process(). Here's the part of xsl file: ... <xsl:template match="/root"> <xsl:for-each select="node"> <xsl:sort select="@id" data-type="number" /> ... </xsl:for-each> </xsl:template> ... It works ok. But if we remove data-type attribute from <xsl:sort> tag or change it to "text", the PHP crashes. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=23128&edit=1
