#26786 [Opn->Fbk]: with CGI, shell_exec()/backtick operator never returns

ID: 26786 Updated by: sniper@php.net Reported By: php dot chad at cropcirclesystems dot net -Status: Open +Status: Feedback Bug Type: CGI related Operating System: FreeBSD 5.1-p11 PHP Version: 4.3.4 New Comment: Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip Also, I could not access that phpinfo() page. So put your full configure line here. (or rather, cut it down to bare minimum, configure the snapshot using that cut down version and test again) Previous Comments: ------------------------------------------------------------------------ [2004-01-04 15:18:13] php dot chad at cropcirclesystems dot net Description: ------------ Using the Apache module or the CLI, everything works just fine. However, when using PHP via CGI, the backticks operator and the shell_exec() function both never return, however, they DO successfully execute the command! php blocks idle, not racing. Seems similar to #11224 in effect, but #11224 claims it was fixed in 4.0.6! Also, #11224 is on Windows using IIS! (yuck!) I've built PHP 4.3.4 via FreeBSD's port system, so it could be their problem. I have yet to test this with another operating system. My php.ini is your php.ini- recommended. My configure line is rather large, but can be seen at 'http://www.cropcirclesystems.net/phpinfo.php', although I have many optional modules, I've also tried this with FreeBSD's port's default module selections. I built using: cd /usr/ports/lang/php4; make WITHOUT_CLI=yes WITHOUT_APACHE=yes install; cp /usr/ local/etc/php.ini-recommended /usr/local/etc/php.ini Reproduce code: --------------- <?php print shell_exec('/full/path/to/some/executable'); ?> Expected result: ---------------- the stdout of the executable Actual result: -------------- indefinate waiting. The executable gets executed, though. I'd be happy to follow up with more testing/information. I'll let you know after I try the same thing on FreeBSD 4.9 and Gentoo Linux. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26786&edit=1
