Add some design time readable metadata for built-in beans of CDI-implementations.

Project: CDI Specification Issues
Issue Type: Feature Request
Reporter: Alexey Kazakov
We need such metadata for tooling.
It would be very helpful to have some metadata for beans which implement spec required
services (BeanManager, ...)
Or for any other beans which CDI implementations register programmatically and which
should be available for users.
For example Weld loads some beans from jars which don't have beans.xml but some of
those beans are available for injections.
So far we don't have any documented way to recognize such beans.

Dan Allen commented on CDI-113:
-------------------------------
I don't think that Weld loads any beans from jars which don't have beans.xml. Any
built-in bean that Weld provides is clearly documented in the CDI specification. Examples
include BeanManager, UserTransaction and a few others (security principle, validation
factory). Some may depend on the runtime environment (such as when Weld runs in a Servlet
environment). However, these cases are well specified.
It's accurate to say that extensions can load beans from jars which don't have
beans.xml. The most basic example is using the BeforeBeanDiscovery#addAnnotatedType() in
an extension method that observes this event. It's those cases when metadata is
probably useful. Granted, this would have been possible had the XML configuration schema
been approved. So perhaps the right approach is to pursue that request.

> However, these cases are well specified.
They are well
specified for runtime but not for tools.
How should tools recognize BeanManager implementations? What if there are a few classes
that implement this interface? Only particular CDI container knows what to load to provide
spec required services.
And one more problem. CDI container don't have to look in jars without beans.xml at
all. So no beans.xml no any need to scan such jars. But for tools it's not the case.
Tools have to look in all the jars in class path if they want to find all BeanManager
implementations. Otherwise they need to know all the available CDI-implementations to work
around this problem using hard-coded names/paths.

Dan Allen commented on CDI-113:
-------------------------------
I may have lost you, but why are we talking about multiple BeanManager implementations?
There is only one BeanManager implementation, and that's the one provided by the
runtime environment (JBoss AS). If you see @Inject BeanManager, you just have to assume
that it's a valid injection point based on the rules of CDI. This is a much different
case than injecting an application-defined bean.
If I'm not understanding your concern, please let me know.

Alexey Kazakov commented on CDI-113:
------------------------------------
Nothing limits CDI container to have a few implementation in class path but use the only
one (at least at once).
For runtime it's not a problem. You know that you must provide a BeanManager and you
provide it. But what if the developer added the following class in the classpath (I
don't know why he might do it):
public class MyNotUsedBeanManagerImplimentation implements BeanManager {
...
}
Runtime still works since this dead code is not used by CDI container but how tools can
know that there is some difference between those BeanManager implementations?
Agree that may be this example is too tricky. And for 99.9% there will be the only
implementation for every required service. But I just wanted to show that what is obvious
for runtime is not so for design time.
Second problem may be more important. Even if we know for sure that there is the only one
BeanManager implementation, the only one UserTransaction implementation, etc. we should
scan every jar in the class path since we don't have any marker like beans.xml to skip
not-CDI jars. It may be too long :(

This isn't 100% accurate, Weld also provides some built in beans that are Weld
specific, currently this is only the Context control beans.

How we can find actual bean classes without scanning the entire class path? So far we just

I don't think you should be making BeanManagerImpl available for injection, just
BeanManager (which all impls *must* provide). So hardcode BeanManager, not
BeanManagerImpl.

Why do you need to find actual bean classes? All that you should be making available is
the interfaces provided by the spec.
I think we need to talk about this offline as there is clearly a misunderstanding here,
which I think may stem from the way we did things in Seam 2.

Ok. If it is not interesting to look at particular implementation of built-in beans at all
and having navigation to the interfaces only is enough then JBT doesn't need any
additional metadata. Actually JBT already works in this way - JBIDE-8697.

Pete Muir commented on CDI-113:
-------------------------------
I would say it's actively wrong to have the tool look at the impl of a built in bean,
or to navigate to them. Part of the goal of a specification is to encourage people to
write portable code, encouraging them to look at implementations is not a good way to do
this!
