Zend_Translate issues 'failed to open stream' warning when using a custom adapter

[g10-fred]

Issue is on line 130 of class Zend_Translate, the 'class_exists' function is attempting to autoload a custom adapter as a 'Zend_Translate_Adapter_' and issues a warning when it is not found:

PHP Warning: include_once(Zend/Translate/Adapter/Custom/Translate/Adapter.php): failed to open stream: No such file or directory in /var/www/comm-os/vendor/zf1s/zend-loader/library/Zend/Loader.php on line 134

Requires the 'autoload' parameter of the class_exists function to be set to false.

@g10-fred, no the error comes from Zend/Loader:

• https://github.com/zf1s/zf1/blob/1.13.4/packages/zend-loader/library/Zend/Loader.php#L134

You should stop using Zend_Loader and stick with the composer autoloader. The zf1s/zf1 project is intended to use composer autoloader.

@falkenhawk is it covered anywhere how to stop using Zend_Loader?

@glensc I haven't covered any instructions about moving away from Zend_Loader myself.

However here a reproduction (and/or a stacktrace) from @g10-fred would be great - why it fails, is it a combination of wrong options passed or is it triggered from the zf1 internals somewhere.

Anyway, Requires the 'autoload' parameter of the class_exists function to be set to false. this would not be a solution, as the adapter class is expected to be loaded dynamically with composer, and not preloaded somewhere. We could silence the error with @ eventually, as it is done in other places and let the script proceed instead of triggering a warning.

We have simply have a custom Zend_Translate_Adapter class and we pass the name of the class to Zend_Translate in a Controller Plugin.

Something like:
$translate = new Zend_Translate('Custom_Translate_Adapter', array(), $langLocale, $options);

Here's a stack trace:

related commit which might have caused this issue 76477fb - logic with class_exists must be changed in such cases so it does not trigger a warning, but also not throw an exception, when Zend_Loader_Autoloader is enabled 🤔
