Operating system: Win XP Pro
PHP version: 5CVS-2006-07-01 (snap)
PHP Bug Type: COM related
Bug description: CLI sometimes crashes on Shell.Application
Description:
------------
Sorry I cannot reliably reproduce this but...
php-win.exe often errors, giving me one of those "would you like to report
this to Microsoft dialogs" on account of the $ox=new
COM("Shell.Application"); line. This happens in version 5.1.1 (from about
Dec. 2005) and today's 5.2 Note that it only happens:
1. with php-win.exe
2. in the php-win -a form and not the -r form
3. when the Shell.Application line is present
4. when the execScript line is present
The last two lines and the opener="me" line are not required for the bug
to be shown. They are there so that when you go to the new IE, you can
make it go away by pressing any key.
Also, despite the bug, the new IE appears and the execScript functionality
is present.
// to see the bug, have DOSKEY active, and
// call the file below (named inc.php) a few
// times from a (wrapped) command line with:
// echo ^^^<?php include('inc.php');ieStuff("<strong>Whoever</strong>");
?^^^> | php-win -a
// or
// echo ^^^<?php ieStuff("<strong>Whoever</strong>"); ?^^^> | php-win -d
auto_prepend_file=inc.php -a
Reproduce code:
---------------
<?php
function ieStuff($html) {
// Without this line, the bug does not happen
$ox = new COM("Shell.Application");
// new instance of IE
$ie = new COM("InternetExplorer.Application");
// next line creates a DOM
$ie->Navigate2("about:blank");
// allow for settling
while ($ie->ReadyState!=4) usleep(10000);
$ie->Visible = true;
// next line allows self.close()
$ie->Document->ParentWindow->opener="me";
// escape handler definition
$ie->document->parentWindow->execScript(
"document.onkeypress=function(){window.close();}");
// proof of access to IE
$ie->document->body->innerHTML = $html;
// so escape handler listens
$ie->document->body->focus(); }
?>
Expected result:
----------------
I don't expect to see any CLI error message
Actual result:
--------------
Every so often, sometimes consistently every time, I get a CLI error
dialog box on account of the Shell.Application line, which is not even
used (in the example).
The more windows you have open (IE and otherwise), the more likely the bug
is to show itself. Under 25 windows open, and it doesn't fail much. Also,
the problem tends to surface more readily if you go do your thing and then
come back to the Cmd window 10 or 20 minutes later and then try it again.
Sorry, I can't be more specific. I'm probably as unhappy reporting on an
intermittent bug as you are reading about it.
