Re: We need some explanation ...

2006-11-07 Thread Arnaud Bailly
Hi Vincent,
The architecture is quite clear now, but there remains some questions:
 - I understand that when calling clover:instrument in any phase, this
 triggers a custom lifecycle (clover LC) that runs instrumentInternal
 and then runs the tests so that clover DB gets populated. This
 lifecycle is forked so that original sources are prevented from
 ending up in artifact. 
 - the original question was about the use of process-sources: It
 seemed to me that coverage intsrumentation should be done after all
 sources are generated. Why is this not the case for clover ?

Thx

Yes, exactly.

  sources are generated. Why is this not the case for clover ?

The clover:instrumentInternal goal is bound to the generate-sources phase
(the first phase for sources). The main reason is that any source generated
is usually already tested (the generators are usually tested) and there's
usually no need to write tests for it. Instrumenting the generated sources
would skew the coverage result. Now I agree that it's possible that there
are cases where you'd want the instrumentation to include generated sources.
This is not supported as of now. Actually nobody has asked for this use case
yet...

Thanks
-Vincent

Thanks for the (quick :-)) answer. 

I agree that generated sources are usually
tested and do not need specific tests, so instrumenting them may not
be very useful as far as branch/line coverage is concerned. I can
think however of a use case where you would need coverage of generated
code.

Imagine that your generator provides glue code between
components/classes folloving some pattern of communication and that
you want to cover with your tests the interaction between two
classes. You would need instrumentation information for generated
sources to link standard java method invocation in your classes with
something in your glue code. 

This all depends on what you are trying to cover with your
tests. All tools I am aware of gives you so-called branch or line
coverage, but there exists different coverage information that would
be often more useful to have.

 For the process-sources, its the phase used when what you're processing

 good example though...

 
 Maybe instrumentation for profiling or coverage ? I have however
 checked with the clover plugin and it uses the generate-sources
 phase.

Good day to you too,

Unfortunately, the example is nice but flawed :-( The
maven-clover-plugin is not bound anywhere to the process-sources phase

what happens if the plugin is run before another plugin that generates

But any plugin that need to do some blakc magic on the sources (AOP,

Good day to you, Arnaud,

Thanks for the correction :-) my eyes must be playing tricks on me :-P

Anyway, I'm not sure though if another goal would be bound to the same phase
as instrumentInternal. Though I haven't really disected the code to its very
core, the architecture provided in [1] seems to indicate that it is forked
to its own lifecycle (clover lifecycle). But I haven't trace that part yet
where forking happens so I'm not sure if that architectural design is still

Yes, there is a custom lifecycle, see [1]. But I do not know what really
happens with this lifecycle fork: I must confess I am still confused
by this forking stuff. 

According to the descriptor, the clover plugin
runs: generate-sources, test and integration-test phases, with goal
instrumentInternal bound to generate-sources. This implies that no
other goals from other plugins are run in this phase, so generated

Hi Arnaud,

The clover plugin is presumably one of the most complex m2 plugin. I had
some architecture diagrams to explain how it worked but I've hidden them as
the code has changed a bit and I hadn't had the time to update the diagrams.
I'll try to find some time today to update them and republish them.

Re: We need some explanation ...

2006-11-05 Thread franz see

Good day to you, David,

The generate-sources, phase is used for auto code generation. An example for
this would be the maven-modello-plugin (see [1]) which allows the creation
of Xpp3 Readers, Writers and the corresponding models. Running an XDoclet
maven goal would most probably be bound here if that goal produces source
codes.

For the process-sources, its the phase used when what you're processing
(prior to compilation) is the sources themselves. hhmm..can't think of a
good example though...

The generate-resources phase on the other hand, is like the generate-sources
phase, except that this auto generates resources (i.e. xmls, property files)
instead of codes. An example which uses that is the maven-eclipse-plugin.
the eclipse:eclipse goal which generates the .classpath and .project
resources is bound to that phase (see [2] for the released documentation and
for [3] for the staged unreleased documentation). And if you have an XDoclet
goal which produces resources such as schemas, that goal would most likely
be bound to this goal.

And as for the process-resources phase, this phase handles the
resources-related processes prior to compilation. An example of this is the
maven-resources-plugin, which filters and copies resources (see [4] for the
released documentation and for [5] for the staged unreleased documentation).
And example of a resource would be a property file. 

For more information about the lifecycle, kindly see [6]. And if you want to
suggest somethings or have some feebdacks or something, you might want to
create a jira issue in [7] under the Documentation: Introduction
component.

In relation to the eclipse plugin, only one goal (that i know of that works)
is bound to a lifecycle phase, and that's the eclipse:eclipse goal which is
bound to the generate-resources phase.

And with regards to the goals, the current plugin documentations now have
their goals documented. However, not all of these new plugin documentations
have been released yet (plugin documentations released after Oct 16, 2006
are probably the latest ones..since it was the last time [8] was updated).
But nonetheless, if you have any comments about the plugin documentation,
you can create a jira issue under that plugin ([9] for maven-eclipse-plugin,
[10] for maven-resources-pluign, etc).

And lastly, goals are plugin-specific (a plugin consists of 1 or more
goals). Phases are were a goal can bind to so that you can use a lifecycle
(sequence of phases) to execute your goals in a specific manner. 

At least, these are my notes. :-) Did I answer your question? 

Cheers,
Franz

  After the message about the documentation, I kind of felt the same
 way.  I
  like ANT because I can look at my build.xml file and see what each
 target
  will do exactly.  Maven2 is much different but it's more
 standard.  That's
  good because we all can begin to learn each goal and then know as we
 issue
  the keystroke what's going to happen and what to expect.
 
  I started moving around some of the texts on the Maven User WIKI at
  http://docs.codehaus.org/display/MAVENUSER/Home
 
  As long as my interest holds, I plan to keep working on the basic
  documentation for using Maven.  I'm interested in Appfuse now and
 they've
  moved to Maven2 and away from my old friend ANT.  This message is a
  request
  to get some answers on some goals that I'm not exactly familiar with
 yet.
  I'm using the Maven plugin for Eclipse and I figured that I would start
  with
  explanation of the lifecycle phases.
 
  Let's document through mvn compile.
 
  - Initialize
  -Generate sources
  -Process sources
  -Generate resources
  -Process resources
  -compile
 
  I understand initialize and compile.  Can someone relate the ones in
  between
  for me in relation to doing things e.g. running xdoclet, moving
 properties
  files, building schema, etc.?  The official documentation discusses
  validate, compile, and test.  I understand these, but the eclipse
 plugin
  has
  more.  We should document goals that are used the most for various
 types
  of
  projects.
 
  If this was ANT, I'd know what these goals did exactly.  Can someone
 tell
  me
  what the above goals will do when I run them in eclipse?  Also, I
 imagine
  some of them may or may not be there.  That would be worth documenting
 for
  folks on the WIKI.
 
  Thanks,
 
  David Whitehurst

 Good day to you, David,

 The generate-sources, phase is used for auto code generation. An example for
 this would be the maven-modello-plugin (see [1]) which allows the creation
 of Xpp3 Readers, Writers and the corresponding models. Running an XDoclet
 maven goal would most probably be bound here if that goal produces source
 codes.

 For the process-sources, its the phase used when what you're processing
 (prior to compilation) is the sources themselves. hhmm..can't think of a
 good example though...


Maybe instrumentation for profiling or coverage ? I have however
checked with the clover plugin and it uses the generate-sources
phase. 

My 50cents
