Status: No Feedback
Bug Type: Program Execution
Operating System: SUN OS
PHP Version: 4.3.10
New Comment:
Tested script from <thomas dot wetzler at siemens dot com> on php4.4.0
cli/apache2 and php4-STABLE-200507190640 on Linux server and ALL
samples worked.
Found this bug searching for a similar (maybe the same) issue related
to popen/freads calling SVN. I modified this test script and ran tests
using 4.4.0 and php4-STABLE-200507190640 with the following results:
script
------
#!/usr/local/apache2/php/bin/php
#
<?
for ($i=0; $i<10; $i++) {
$statement = "/usr/local/subversion/bin/svn help";
echo "\n\n$i***************************\n";
$handle = popen($statement, 'r');
echo "Subprozess: '$handle'; " . gettype($handle) . "\n";
$output = '';
while (!feof($handle)) {
$output .= fgets($handle);
}
echo $output;
pclose($handle);
}
?>
results

We tried out PHP Version 5. With the commandline (php.exe) it seems to
work but with the mod_php-module we get the same failure.
Because the testing of our application take a long time, it would be
good if you can find a solution for Version 4.

Description:
------------
While sequentially opening and closing several processes via popen (or
passthru, exec and '' command) php looses some processes. This takes
place if, for instance, the user presses the reload-button on a website
several times.
With the coding below, you can reproduce the failure (takes place on
commandline (php.exe) and in apache module (mod_php)).
Reproduce code:
---------------
#!/wir/webadmin/share/php4/bin/php
#
<?
for ($i=0; $i<900; $i++) {
$statement = "ls -l";
echo "\n\n$i***************************\n";
$handle = popen($statement, 'r');
echo "Subprozess: '$handle'; " . gettype($handle) . "\n";
while (!feof($handle))
{
echo fread($handle, 8192);
}
pclose($handle);
}
?>
programcall: <progname> > <resultfile>
Expected result:
----------------
Within the result-file, there should be 900 times the same result from
the system command (here ls -l command).
