vbulletin's error notice problem

[squishi]

I recently upgraded from vbulletin 3.8.4 (Patched) to 3.8.7.
On a custom page, I turned error reporting on:

PHP Code:

error_reporting(E_ALL & E_NOTICE); 


This setting used to be at "~E_NOTICE", so I never noticed the warning messages.

And there are loads of them.

I tried to fix some of the bugs, but there must be some other reason.

Take this one for example:

Notice: Undefined index: jsver in /forum/includes/class_core.php on line 1438

class_core.php:

PHP Code:

$this->registry->options['simpleversion'] = SIMPLE_VERSION . $this->registry->config['Misc']['jsver']; 


I assume this is accessing a setting that is not defined in the config.php.
I checked the config.php of a freshly downloaded vb script. The index "jsver" cannot be found in that file. So why is the script searching for it?


Out of curiosity, I turned the notices on for the forumdisplay.php and was hit with hundreds of notice messages.

Will a standard installation of vbulletin produce any notices if error_reporting is set to the appropriate value?

This is extremely shitty programming style! :down:

Most of the errors are undefined array index problems. They could be fixed very easily by not writing sloppy code.
Did you let your interns program vbulletin?

Maybe the developers can learn something from this small experiment:
copy this in a php file and run it:

PHP Code:

<?php

error_reporting(0);

echo "TEST 1:<br />";
echo "notice message [if($_GET['abcdef'])]<br /><br />";

$start  = microtime(true);
for($i = 1; $i < 100000; $i++)
{
    if($_GET['abcdef'])
    {
        //
    }
}
$end = microtime(true);

echo "RESULT 1: ".($end - $start)."<br /><br /><br />";

echo "TEST 2:<br />";
echo "@ parameter [if(@$_GET['abcdef'])]<br /><br />";

$start  = microtime(true);
for($i = 1; $i < 100000; $i++)
{
    if(@$_GET['abcdef'])
    {
        //
    }
}
$end = microtime(true);

echo "RESULT 2: ".($end - $start)."<br /><br /><br />";

echo "TEST 3:<br />";
echo "isset check [if(isset($_GET['abcdef']))]<br /><br />";

$start  = microtime(true);
for($i = 1; $i < 100000; $i++)
{
    if(isset($_GET['abcdef']))
    {
        //
    }
}
$end = microtime(true);

echo "RESULT 3: ".($end - $start)."<br /><br /><br />";

The result:

TEST 1:
notice message [if($_GET['abcdef'])]

RESULT 1: 0.071149826049805


TEST 2:
@ parameter [if(@$_GET['abcdef'])]

RESULT 2: 0.075546979904175


TEST 3:
isset check [if(isset($_GET['abcdef']))]

RESULT 3: 0.01532506942749

Sloppy programming does not pay off!
