Subject: Memory leak when calling WS using wsdl
Download (untitled) / with headers
text/plain 468b
There appears to be a slow memory leak when using a .wsdl file to make SOAP calls. Sample code attached. The attached script grew from ~11MB at start to ~20MB RES size (VIRT went from 14MB to ~24MB) after running ~40,000 query loops. Confirmed this under both Ubuntu 6.06 LTS (perl 5.8.7) and Debian 4.0 STABLE (perl 5.8.8) with SOAP::Lite 0.71.07 installed from CPAN. Attached code is .pl file, .wsdl, as well as a PHP-based server which runs from the same .wsdl.
Subject: Authentication_test.php
<?php // Version 1.0 // This is a sample PHP to implement an authentication web service // our servers will call your web service to Accept or Reject connections // If code is to provide a starting point for a developer wanting to create their own // authentication rules for their streaming. // // If you modify this script or create a new one make sure you keep your SOAP messages compatible // with the definitions inside Authentication.wsdl // // If you change the WSDL definitions or SOAP structure the client may not understand how to // interact with your code // Create a soap server object based off the standard WSDL provided. $server = new soapserver("Auth.wsdl", array('encoding'=>'UTF-8')); /* function: Authenticate * Purpose: This is the method that will be called during each connection * Use one of the input parameters as a criteria to authenticate the client * * Comments: Keep the duration between entering and exiting this function to a minimum * The client cannot begin streaming until you send back a result * If an extremely long time has lapsed the web service client may also terminate the * connection * * Inputs: * (strings)account The name of the account associated with this request * This could be useful if you have multiple accounts, otherwise is will * always contain the same value. * * (strings)token This is the unique string that was passed into the Player * This can be a alpha numeric and should not be predictable * * (strings)referrer This is the referrer passed to the server, usually this is the url * to the .swf * * (strings)sourceURL This is the full URL being requested from the server * * (strings)ip This is the IP of the client connecting to the server * * Output: * (int)0 Reject Access * (int)1 Accept Access */ function Authenticate($account, $token, $referrer, $sourceurl, $ip) { // A very simple demonstration of how you can accept/reject connection on specific criteria // In this case if the token is an even number we will allow access, if the number is odd we reject if($token % 2 == 0) { $retval = "1"; } else { $retval = "0"; } return $retval; // return ACCEPT(1) or REJECT(0) } // map the SOAP operation to the appropriate PHP function above $server->addFunction("Authenticate"); // This is just some extra code to show what web service function is available if you browse this PHP if ($_SERVER["REQUEST_METHOD"] == "POST") // If this is a post from the web service client then handle soap { header("Content-Type: text/xml"); // The client calling this code expects XML content-type $server->handle(); // process the soap } else // this is probably a browser querying what function is available in this php { echo "This SOAP server can handle following functions:<br> "; $functions = $server->getFunctions(); foreach($functions as $func) { echo $func . "<br>"; } } ?>

Sorry for the duplicate entry (web UI hung so I clicked submit twice), please close this one.
Just closed the duplicate - #37040 is the original report. Martin
