As we all know Drupal 8 has lots of new stuff. One of these items is based on Dependency Injection and result in a new file stored at sites/defaults/files/php/service_container/service_container_prod.php/e7000f005xxx.php and created very early during the bootstrap of Drupal. But what is it's contents?

Who is calling my function so many times? With devel module and some probing using debug_backtrace and a nifty by ref variable it's a snap.

I sometime need to check arrays for their values dispersed around. Just dumping the array is OK when interested in a particular key or value. But what about those big info arrays from hook_token_info, hook_menu etc. This is what I did.

If you have just changed code (for example deployed a new module or moved an existing one) read http://drupal.org/documentation/rebuild

As a followup on A pinch of Symfony for D8MI? why do we need to squash?

After some more squash and push -f attempts regarding pull request for Symfony I get the hang of it.

But chx said in squash is bad as we loose history on the development process.

So how should we do this on d.o when git phase 3 lands? Those discussion seems to got to a halt.
