POphp - Is php caching classes before creation?
text
Body
copied!<h1>Background Information:</h1> <p>I'm using <a href="http://symfony.com/doc/current/components/console/introduction.html" rel="nofollow">Symfony Console Component</a> to write a console application that is wrapped into a <a href="http://api.symfony.com/2.4/Symfony/Component/Console/Shell.html" rel="nofollow"><code>Shell</code></a> object. I wrote a command named <code>console:reload</code> that empties the array of commands from the <code>Application</code> object, and re-adds commands classes listed under certain directory.</p> <p>This command is run when the shell starts, so, the <code>Application</code> is loaded with the available commands. The classes being loaded are located in a special directory and should follow a simple name rule: <code><CommandName>Command.php</code>:</p> <pre><code>// Inside ReloadCommand->execute() method... $pamperoApp = $this->getApplication(); $pamperoApp->clearCommands(); $namespace = "pampero\\cli\\modules"; foreach(glob(MODULES_DIR . "/*/*Command.php") as $command) { $class = str_replace(".php", "", $namespace . "\\" . basename(dirname($command)) . "\\" . basename($command)); $this->getApplication()->add(new $class); } </code></pre> <p>The autoload provided by Symfony (Composer?) <code>ClassLoader</code> is used:</p> <pre><code>// Main entry point... loader = require_once __DIR__ . '/../vendor/autoload.php'; $loader->set('pampero', __DIR__ . '/../..'); </code></pre> <p>I read the code from <code>ClassLoader</code> class and what it does is to store file name path, so no object caching there.</p> <h1>Here's the problem:</h1> <p>I launch the app: <code>php packages.php</code>. The shell appears after <code>ReloadCommand</code> command being executed. A list of available and loaded commands are ready to be used.</p> <p>If I create a new file, let's say: <code>ExampleCommand.php</code>, and then I type: <code>console:reload</code>, the new command will indeed be added. Now, If I modify the code inside <code>ExampleCommand.php</code> and run <code>console:reload</code> again, the changes made to the class won't take effect.</p> <p>But that's not all. If I remove the example file, call <code>console:reload</code>, create the file again and run: <code>console:reload</code> the command will be added.</p> <h1>Reading:</h1> <p>I have read APC related things, and before creating new classes I have done things like:</p> <pre><code>// Prior adding commands in ReloadCommand apc_clear_cache(); apc_clear_cache('user'); apc_clear_cache('opcode'); </code></pre> <p>Without luck. I've also run <code>apc.php</code> and enabled/disabled <code>apc.enable_cli</code> option. None of those things creates the object represented by the modified file.</p> <p>So my hints and clues about the problems turns to be classes caching when a file/class is found. But how to avoid that for this special case? I don't want to restart the shell if some extra funcionality is added through classes.</p> <p>Any ideas?</p>
