| Summary: | 0002362: When extending a built-in class (DOMXPath), parent constructor never gets called | ||||
| Description: |
Instantiating a class that extends DOMXPath doesn't work, because the parent constructor never gets called. This happens whether or not the child class explicitly calls the parent constructor. Test case: <?php class Broken1 extends DOMXPath { } class Broken2 extends DOMXPath { public function __construct($d) { parent::__construct($d); } } $doc = new DOMDocument(); $doc->loadXml('<cake>chocolate</cake>'); $xpath = new DOMXPath($doc); $broken1 = new Broken1($doc); $broken2 = new Broken2($doc); print " \n"; print "DOMXPath: \n"; print $xpath->query('/cake')->item(0)->textContent; print "\n<hr/>\n"; print "Broken 1: \n"; print $broken1->query('/cake')->item(0)->textContent; print "\n<hr/>\n"; print "Broken 2: \n"; print $broken2->query('/cake')->item(0)->textContent; print "\n<hr/>\n"; ?> When run under Resin/Quercus 3.1.4 or 3.1.s080114, this produces the following results: /home/david/quercus/resin-3.1.s080114/webapps/ROOT/inherit-test.php:10: Warning: function '__construct' has 1 required arguments, but only 0 were provided /home/david/quercus/resin-3.1.s080114/webapps/ROOT/inherit-test.php:11: Warning: function '__construct' has 1 required arguments, but only 0 were provided DOMXPath: chocolate Broken 1: 500 Servlet Exception com.caucho.quercus.QuercusException: com.caucho.quercus.lib.dom.DOMXPath.query: null at com.caucho.quercus.env.JavaMethod.invoke(JavaMethod.java:104) at com.caucho.quercus.env.JavaInvoker.callMethod(JavaInvoker.java:604) at com.caucho.quercus.env.ObjectExtValue.callMethod(ObjectExtValue.java:602) at com.caucho.quercus.expr.MethodCallExpr.eval(MethodCallExpr.java:104) at com.caucho.quercus.expr.MethodCallExpr.eval(MethodCallExpr.java:92) at com.caucho.quercus.expr.FieldGetExpr.eval(FieldGetExpr.java:72) at com.caucho.quercus.env.JavaInvoker.evalArguments(JavaInvoker.java:415) at com.caucho.quercus.expr.FunctionExpr.evalImpl(FunctionExpr.java:170) at com.caucho.quercus.expr.FunctionExpr.eval(FunctionExpr.java:126) at com.caucho.quercus.program.ExprStatement.execute(ExprStatement.java:64) at com.caucho.quercus.program.BlockStatement.execute(BlockStatement.java:99) at com.caucho.quercus.program.QuercusProgram.execute(QuercusProgram.java:239) at com.caucho.quercus.page.InterpretedPage.execute(InterpretedPage.java:61) at com.caucho.quercus.page.QuercusPage.executeTop(QuercusPage.java:119) at com.caucho.quercus.servlet.ResinQuercusServlet.service(ResinQuercusServlet.java:146) at com.caucho.quercus.servlet.QuercusServlet.service(QuercusServlet.java:353) at javax.servlet.http.HttpServlet.service(HttpServlet.java:91) at com.caucho.server.dispatch.ServletFilterChain.doFilter(ServletFilterChain.java:103) at com.caucho.server.webapp.WebAppFilterChain.doFilter(WebAppFilterChain.java:181) at com.caucho.server.dispatch.ServletInvocation.service(ServletInvocation.java:266) at com.caucho.server.http.HttpRequest.handleRequest(HttpRequest.java:268) at com.caucho.server.port.TcpConnection.run(TcpConnection.java:603) at com.caucho.util.ThreadPool$Item.runTasks(ThreadPool.java:721) at com.caucho.util.ThreadPool$Item.run(ThreadPool.java:643) at java.lang.Thread.run(Thread.java:613) Caused by: java.lang.NullPointerException at com.caucho.quercus.lib.dom.DOMXPath.query(DOMXPath.java:99) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at com.caucho.quercus.env.JavaMethod.invoke(JavaMethod.java:97) at com.caucho.quercus.env.JavaInvoker.callMethod(JavaInvoker.java:604) at com.caucho.quercus.env.ObjectExtValue.callMethod(ObjectExtValue.java:602) at com.caucho.quercus.expr.MethodCallExpr.eval(MethodCallExpr.java:104) at com.caucho.quercus.expr.MethodCallExpr.eval(MethodCallExpr.java:92) at com.caucho.quercus.expr.FieldGetExpr.eval(FieldGetExpr.java:72) at com.caucho.quercus.env.JavaInvoker.evalArguments(JavaInvoker.java:415) at com.caucho.quercus.expr.FunctionExpr.evalImpl(FunctionExpr.java:170) at com.caucho.quercus.expr.FunctionExpr.eval(FunctionExpr.java:126) at com.caucho.quercus.program.ExprStatement.execute(ExprStatement.java:64) at com.caucho.quercus.program.BlockStatement.execute(BlockStatement.java:99) at com.caucho.quercus.program.QuercusProgram.execute(QuercusProgram.java:239) at com.caucho.quercus.page.InterpretedPage.execute(InterpretedPage.java:61) at com.caucho.quercus.page.QuercusPage.executeTop(QuercusPage.java:119) at com.caucho.quercus.servlet.ResinQuercusServlet.service(ResinQuercusServlet.java:146) at com.caucho.quercus.servlet.QuercusServlet.service(QuercusServlet.java:353) at javax.servlet.http.HttpServlet.service(HttpServlet.java:91) at com.caucho.server.dispatch.ServletFilterChain.doFilter(ServletFilterChain.java:103) at com.caucho.server.webapp.WebAppFilterChain.doFilter(WebAppFilterChain.java:181) at com.caucho.server.dispatch.ServletInvocation.service(ServletInvocation.java:266) at com.caucho.server.http.HttpRequest.handleRequest(HttpRequest.java:268) at com.caucho.server.port.TcpConnection.run(TcpConnection.java:603) at com.caucho.util.ThreadPool$Item.runTasks(ThreadPool.java:721) at com.caucho.util.ThreadPool$Item.run(ThreadPool.java:643) at java.lang.Thread.run(Thread.java:613) If you comment out the $broken1->query() line, then the same 500 error/NPE happens on the $broken2->query() line. The expected result, run against PHP 5.2.3 is: DOMXPath: chocolate <hr/> Broken 1: chocolate <hr/> Broken 2: chocolate <hr/> |
