Incompatibility with Gii's diff

[rcoelho]

framework/gii/components/TextDiff.php lines 6-8 have require_once that don't work when the extension is activated.

can you explain what you mean with don't work? I haven't seen any problems with gii and zend autoloader myself.

Sure. The code is generated without problems. But if you click in the "diff" link in Gii, there's a PHP error:
require_once(Text/Diff.php): failed to open stream: No such file or directory (/.../framework/gii/components/TextDiff.php:6)

This might be old, but I just ran into this issue. I found two possible ways to fix this issue:

1. Add the following to your main.php config file 'system.gii.components.Pear.*'. I recommend disabling the line in production if you are not going use the TextDiff class.

// autoloading model and component classes
'import'=>array(
   'application.models.*',
   'application.components.*',
   'system.gii.components.Pear.*'
),

OR

2. Copy the gii/components/Pear/Text folder directly into your components folder. This method is good if you want to override the way that the TextDiff functionality works.

I just ran into this I know this post is old would like to clarify the problem. The setting of param append = true on Yii::registerAutoloader function sets YiiBase::enableIncludePath = false which is used for Yii's autoloader. With YiiBase::enableIncludePath = false the import of gii.components.Pear.* is not found.

so to fix the issue just remove the append param from Yii::registerAutoloader and the problem is fixed.
I also changed this part of the code to match prefix
if(strpos($className, $prefix.'') !== false)
if(strpos($className, $prefix.'') === 0)
