Subject: Enhancements to Tuscany logging and trace
I've been looking at the Tuscany "tracing-aspectj" module and have been
contemplating a few enhancements.
For those who have not run this module, the Aspect-Oriented-Programming
(AOP) based trace in Tuscany allows a Java agent (AspectJ) to run while
Tuscany is running. This special agent can detect entry and exit of
methods and other runtime conditions. The nice feature about this AOP
style programming, is that the Tuscany code does not have to be littered
with logging and tracing calls, and so the code base remains much more
readable. Additionally, the Tuscany users of logging and trace do not
need to be dependent on developers to add the tracing code to the code
base. (How many times have you run a trace and it misses the method you
are interested in? Or you thought the trace was too verbose and you
wished you could trace one method? AOP facilitates this.)
1) I would like to break out some of the logging and trace pointcuts
into the runtime configuration file (aop.xml). Currently the trace
points are compiled into the module. Users must recompile to trace other
than "* org.apache.tuscany.sca..*.*(..)" methods. It would be nice if
this were in the config file. Then users interested in just one thing,
say Java introspection, could change this to
"org.apache.tuscany.sca.interfacedef.java.impl.*Introspection*", and
this would take effect without recompiling.
2) I would like to add a few pointcuts to look at constructors.
3) I would like to make a few explicit timing pointcuts and aspects for
those who want to time certain Tuscany transactions, methods, or
constructors.
4) I would like to run these with Tomcat or WebSphere or other to ensure
they work and trace some useful things.
5) Finally, I would like to add a few user guide articles on how to use
this.
Please, if you have any ideas or comments about logging and tracing in
Tuscany, please let me know.
