Symfony2 Services循环依赖吗？
[英]Symfony2 Services Circular dependency?
问题描述
UPDATE: The problem wasn't on the server code, but on the Behat execution environment. 
更新：问题不在服务器代码上，而是在Behat执行环境上。
I'm developing a Symfony2 project, and somehow, after many months of development I've introduced a bug which crashes the entire application and outputs the following error message: 我正在开发一个Symfony2项目，以某种方式，经过几个月的开发，我引入了一个错误，该错误使整个应用程序崩溃，并输出以下错误消息：
PHP Fatal error: Maximum function nesting level of '100' reached, aborting! in /var/www/main_api/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/Container.php on line 289

I think this is because a circular dependency between services, is it possible? 我认为这是因为服务之间存在循环依赖关系，这可能吗？ If that's the case, is there a systematic way to find circular dependencies between services in Symfony? 如果是这样，是否有系统的方法可以在Symfony中找到服务之间的循环依赖关系？

At the end, it wasn't a problem in my code, but in the Behat execution environment. 最后，这不是我的代码中的问题，而是Behat执行环境中的问题。
I had to change the max nesting level with the following entry in the /etc/php5/cli/php.ini file (I'm on Debian): 我必须使用/etc/php5/cli/php.ini文件中的以下条目更改最大嵌套级别（我在Debian上）：
[XDebug]
xdebug.max_nesting_level = 1000
