#43897 [NEW]: $ie not cleared on IE quit

From: csaba at alum dot mit dot edu Operating system: Win XP Pro PHP version: 5.2.5 PHP Bug Type: COM related Bug description: $ie not cleared on IE quit Description: ------------ In the code below, if the visible IE is closed, whether by script or by the user, the bug manifests itself. What will happen is that there will be a sequence of (ReadyState) 4's displayed while IE is extant. When IE is closed, "Exiting" should be printed, but what happens is that a sequence of ReadyState=0's is printed, which is a bug. The bug only happens if there are no instances of IE when the script is run. The second instance of $ie has to be 'static' Csaba Gabor from Vienna Reproduce code: --------------- <?php // IE being closed doesn't terminate script // if there are no IE instances on startup $ie = new COM("InternetExplorer.Application"); $ie->visible = true; $ie->Navigate2 ("about:blank"); $ie2 = new COM("InternetExplorer.Application"); try { while ($ie->ReadyState>=0) { print $ie->ReadyState; com_message_pump(200); } } catch (com_exception $e) {} print "Exiting"; ?> Expected result: ---------------- I expect to see a sequence of 4s until I close IE, and then I expect to see Exiting printed Actual result: -------------- A sequence of 4s is printed, but when I close IE a sequence of 0s is printed which doesn't terminate till I use the windows task manager (ctrl+alt+delete) to kill the iexplore process. (One could also use ctrl+C in the Cmd window, but that leaves a hidden IE instance, so the bug won't show itself next time around, until the IE is removed). The bug manifests itself without user actions if $ie->Quit(); is inserted right above the 'try' line If there is already an instance of IE in existence, then the bug does not happen. The bug will also show itself if the '$ie2' line is replaced with: ieStatic(); function ieStatic() { static $ie; $ie = new COM("InternetExplorer.Application"); } -- Edit bug report at http://bugs.php.net/?id=43897&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=43897&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=43897&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=43897&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=43897&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=43897&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=43897&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=43897&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=43897&r=needscript Try newer version: http://bugs.php.net/fix.php?id=43897&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=43897&r=support Expected behavior: http://bugs.php.net/fix.php?id=43897&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=43897&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=43897&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=43897&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=43897&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=43897&r=dst IIS Stability: http://bugs.php.net/fix.php?id=43897&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=43897&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=43897&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=43897&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=43897&r=mysqlcfg
