DDC-73: Lifecycle Events only work with undocumented @HasLifecycleCallbacks in Annonation classes

[doctrinebot]

Jira issue originally created by user nicokaiser:

When using Docblock Annotations, Lifecycle Events don't work as described here:
http://www.doctrine-project.org/documentation/manual/2_0/en/events

Functions with e.g. "@PrePersist" annonations are not called unless the class(!) has "@HasLifecycleCallbacks" annotation in its class header docblock.

This behavior should be either documented or changed (no need for the @HasLifecycleCallbacks annotation)

Working patch to trunk(r6683)

WIth this patch the foreach ran every time, but as metadata are cached, I guess that will not be a problem.

Comment created by romanb:

This should rather be fixed in the documentation instead. I think @HasLifecycleCallbacks is useful not only to save some overhead but also as a visual clue to quickly see whether a class has lifecycle callbacks without looking at all methods.

Comment created by @guilhermeblanco:

I think the opposite.

Overhead will only exist during metadata creation.
It's then irrelevant since we strongly suggest a cache mechanism at the top of metadata information.

I'm +1 to commit suggested patch.

Comment created by romanb:

Its far from irrelevant. Everything should be as fast as possible and during development you usually dont use APC/memcache as metadata cache because you would have to clear it manually after every change. Its simply not worth this absolutely minor convenience that we iterate over *all* methods of all entity classes just to look for lifecycle callbacks.

Again, this needs to be fixed in the documentation.

Comment created by romanb:

And to make it even clearer: Not even a metadata cache is the ultimate thing for performance since the unserialization is not very fast either. So please dont ever think something is irrelevant. This is php and php is pretty slow.
