#34112 [Opn->Bgs]: Memory leak when initiating COM object and then destroying it

ID: 34112 Updated by: sniper@php.net Reported By: James_Brigham at hotmail dot com -Status: Open +Status: Bogus Bug Type: COM related Operating System: Windows 2000 or Windows 2003 PHP Version: 5.0.4 New Comment: Any memory any PHP function reserves during the REQUEST (the one you start when you either run a script from command line or access it via web) it frees AFTER the script has been run. This is expected behaviour -> not bug. Previous Comments: ------------------------------------------------------------------------ [2005-08-15 18:17:50] James_Brigham at hotmail dot com I feel the answer to this problem is very vague and the true problem is being ignored and glossed over. ------------------------------------------------------------------------ [2005-08-13 01:06:24] James_Brigham at hotmail dot com Could you explain what you mean by "request is ended"? I would have thought that the request is ended by the time I received my result set. Then after I have my result set, I unset it... ------------------------------------------------------------------------ [2005-08-13 01:00:28] sniper@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php This is not something unique to COM but general 'problem' of PHP. All memory is really cleaned up after request is ended. ------------------------------------------------------------------------ [2005-08-13 00:31:12] James_Brigham at hotmail dot com if you comment out the query lines, then the memory leak seems to go away... the lines I commented out were: //$threadRecords = $wmi->ExecQuery("SELECT * FROM Win32_PerfRawData_PerfProc_Process WHERE Name = '" . $sProcName . "'"); //execute a wmi query against our com object //foreach ($threadRecords as $threadcount) //loop through the resules //{ //echo("Server:[" . $aryHost[$i] . "] Name: " . $threadcount->Name . " Count: " . $threadcount->ThreadCount . "\r\n"); //for each result output basic info to the screen //} ------------------------------------------------------------------------ [2005-08-13 00:27:39] James_Brigham at hotmail dot com As suggested, I have downloaded the latest release from: http://snaps.php.net/win32/php5-win32-latest.zip and I still see the same memory leak. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
