Operating system: DG/UX
PHP version: 4.3.4
PHP Bug Type: Apache related
Bug description: exec(), system() and backtick give maximum execution time error with
Apache
Description:
------------
These functions work fine using the CLI but when used with Apache give a
spurious execution timeout error. I tried setting the timeout to 30000
and it still happened immediately. The problem occurs with any command
that I try to call using system(), exec() or backtick. I do not have
safe-mode enabled.
I did have a couple of porting problems with DG/UX. I had to add #include
<sys/dir.h> to main/php_scandir.h and
double expm1(double x)
{
return(exp(x));
}
before #include "php.h" in ext/standard/math.c
'./configure' '--with-ingres=/OI/ingres' '--without-mysql' '--enable-ftp'
'--enable-cli' '--enable-cgi'
'--with-apache=/usr/opt/apache/apache_1.3.29'
php.ini:
safe_mode_exec_dir = /usr/
log_errors = On
report_memleaks = Off
track_errors = On
error_log = /usr/opt/apache/www/logs/php.log
sendmail_from = [EMAIL PROTECTED]
ingres.allow_persistent = Off
ingres.default_database = divtest
ingres.default_user = devdba
Reproduce code:
---------------
<?php
print "<html>\n";
print "<h2 align='center'>Attempting to run `ls -l` </h2>\n";
$list = `ls -l`;
foreach($list as $value) {
print "$list<br>\n";
print "</html>\n";
?>
Expected result:
----------------
Attempting to run `ls -l`
