Bug #76070 [NEW]: SoapServer::handle() catches some exceptions, but not all

From: magnar at myrtveit dot com Operating system: Windows PHP version: 7.1.15 Package: SOAP related Bug Type: Bug Bug description:SoapServer::handle() catches some exceptions, but not all Description: ------------ Sometimes exceptions are caught by SoapServer::handle(), and sometimes not. Particularly, exceptions of type Error are caught, while exceptions of type Exception are not. Consider the test script. There are two lines throwing exceptions that are commented out. By sending a request to the soap server, the file response.txt is created with the expected soap response. By uncommenting the first exception (1) and sending a request to the soap server, the file exception.txt is created with the following contents: Uncaught exception: bar By uncommenting the second exception (2) and sending a request to the soap server, the file exception.txt is not created! But the file response.txt is created with the following contents: <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Body><SOAP-ENV:Fault><faultcode>SOAP-ENV:Server</faultcode><faultstring>foo</faultstring></SOAP-ENV:Fault></SOAP-ENV:Body></SOAP-ENV:Envelope> It is surprising that the second exception never reaches the exception handler. Instead, the exception seems to be caught inside SoapServer::handle(), and the exception message is sent as a soap fault to the client. Test script: --------------- Server script, uncomment the exceptions, one after the other, to see the strange behavior: <?php set_exception_handler(function(Throwable $Exception) { file_put_contents(__DIR__.'/exception.txt', 'Uncaught exception: '.$Exception->getMessage()); }); function SoapFunction() { // throw new Exception('bar'); // (1) Invokes the exception handler // throw new Error('foo'); // (2) Does not invoke the exception handler! } $Server = new SoapServer(null, ['uri' => 'MyNamespace']); $Server->addFunction('SoapFunction'); ob_start(); $Server->handle(); file_put_contents(__DIR__.'/response.txt', ob_get_flush()); Client script, change http://www.example.com/server.php so that it points to the server script above: <?php $Client = new SoapClient(null, ['uri' => 'MyNamespace', 'location' => 'http://www.example.com/server.php']); $Client->__soapCall('SoapFunction', []); Expected result: ---------------- By uncommenting the second exception (2) and sending a request to the soap server, I would expect that the file exception.txt was created with the following contents: Uncaught exception: foo Actual result: -------------- By uncommenting the second exception (2) and sending a request to the soap server, the file response.txt is created with the following contents: <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Body><SOAP-ENV:Fault><faultcode>SOAP-ENV:Server</faultcode><faultstring>foo</faultstring></SOAP-ENV:Fault></SOAP-ENV:Body></SOAP-ENV:Envelope> -- Edit bug report at https://bugs.php.net/bug.php?id=76070&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=76070&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=76070&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=76070&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=76070&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=76070&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=76070&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=76070&r=needscript Try newer version: https://bugs.php.net/fix.php?id=76070&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=76070&r=support Expected behavior: https://bugs.php.net/fix.php?id=76070&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=76070&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=76070&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=76070&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=76070&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=76070&r=dst IIS Stability: https://bugs.php.net/fix.php?id=76070&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=76070&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=76070&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=76070&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=76070&r=mysqlcfg
