#45376 [Opn->Bgs]: popen causes HTTP Error 502.2

ID: 45376 Updated by: jani@php.net Reported By: louis at steelbytes dot com -Status: Open +Status: Bogus Bug Type: CGI related Operating System: Vista SP1 x64 PHP Version: 5.2.6 New Comment: 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 Previous Comments: ------------------------------------------------------------------------ [2008-06-27 09:48:58] louis at steelbytes dot com 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.
