PHP Bug Type: CGI related
Bug description: popen causes HTTP Error 502.2
Description:
------------
1. proc_open('I_dont_exist.exe') returns true. I feel it shouldn't (I'm
guessing this is because php launches cmd.exe and asks it to run
I_dont_exist.exe)
2. popen('I_dont_exist.exe') returns true if I execute the script from the
commandline using php.exe -n -f test.php (see above for what I would
expect), but if I execute it via php-cgi.exe in IIS, I get HTTP Error 502.2
- Bad Gateway (see below).
Reproduce code:
---------------
$proc = @proc_open(
'c:\\I_dont_exist1.exe'
,array( 0=>array('file','nul','r'), 1=>array('file','nul','w'),
2=>array('file','nul','w') )
,$pipes
);
if ($proc===false)
die('failed proc_open');
proc_close($proc);
echo 'proc_open ok'."<br>\r\n";
$proc = @popen('c:\\I_dont_exist2.exe','r');
if ($proc===false)
die('failed popen');
pclose($proc);
echo 'popen ok'."<br>\r\n";
Expected result:
----------------
ideally both should fail, as the target .exe doesn't exist, but not cause
the script to die
Actual result:
--------------
HTTP Error 502.2 - Bad Gateway
The specified CGI application misbehaved by not returning a complete set
of HTTP headers. The headers it did return are "'c:\I_dont_exist2.exe' is
not recognized as an internal or external command, operable program or
batch file. X-Powered-By: PHP/5.2.6 Content-type: text/html start<br>
proc_open ok<br> popen ok<br> end<br> ".
