Subject [jira] Commented: (COMDEV-11) Mentoring Project for Derby Test and Fix for Jayaram Subramanian
Date Fri, 05 Mar 2010 00:41:27 GMT


Kathey Marsden commented on COMDEV-11:

Mid term review for COMDEV-11 Mentoring Project for Derby Test and Fix for Jayaram Subramanian

Jayaram has been working steadily on Derby since the mentoring session began on January 4,
2010  and interacting well with the community.  He his build and test environment set up and
is working in Eclipse.  He also completed the tutorial and has started contributing to Derby.
   He has been working arduously on the test conversion for autoincrement.sql (DERBY-4509),
which has turned out to be a bigger task that first anticipated. The latest patch shows that
he is gaining a good understanding of the structure and utilities available in JUnit testing
and the patch will be ready to commit after some additonal cleanup.

As a mentor, I have not been as available as I normally like to be with mentees and have been
impressed that Jayaram has stuck with the task and the program without a great deal of support.
 I think he now understands the general flow of the patch, review cycle and learning his way
around the Derby community, product and test infrastructure.  

I believe this session, scheduled to end March 28, should continue and complete on that date,
but that the scope should be changed.  Jayaram should work on completing autoincrement.sql
but remove the other tasks for this session.  We have discussed continuing with a second three
month round of mentoring starting March 29 to convert selectivity.sql and perhaps other tasks,
but will file a separate issue for that.

>             Project:  	 Community Development 
>          Issue Type: Task
>          Components: Mentoring
>         Environment: Apache Derby
>            Reporter: Jayaram Subramanian
>            Priority: Minor
> This mentoring assignment will include test conversions to JUnit and sysinfo improvements.
Details are attached below
> Apache Project of interest: APACHE DERBY
> Benefits to Derby Community
> Getting test cases converted to Junit will help to get rid of maintaining old test cases.
> Name of the mentor: Katherine Marsden
> Expected Deliverables:
> Ramp up (3 weeks)
> Do tutorial. Set up build, test, debug environment. 2) Read up on JUnit testing, review
existing conversions.
>  JUnit conversions (4 weeks)
>  3) Convert autoincrement.sql to JUnit.  This should be a good straight
>  forward starter. I think we need a Jira for this one.
>  4) DERBY-4114.  Convert selectivity.sql This was an old test that was
>  contributed but has old Cloudscape syntax, so will require some
>  thought to convert to use Derby syntax.
>  5) DERBY-4249. Create a simple store recovery test in JUnit.  This
>  will provide a framework for converting store tests.
>  Sysinfo improvements ( 5 weeks)
>  These will improve supportability of DERBY significantly.
>  6) DERBY-4441 - Change sysinfo to print out more specific JVM information.
>  7) DERBY-1272 - log sysinfo to derby.log. Need to to nail down
>  behavior with community and deal with possible security manager
>  issues.
> Duration: Total of 12 weeks with 6 hrs/ week
> Expected Starting Date: Jan 4, 2010
> Skills and Reason for undertaking this project
> The objective of taking up this project is to apply my 2 years of a java skills contributing
to derby community and get involved in higher level of Java
> challenges.
> My recent works in Java/J2EE involved 
> 1) Development of java swing component in JEDIT beanshell environment
> 2)Migration of .Net webservices to J2EE Websphere platform 
> 3)integration of legacy system with TIBCO EMS server. 
> Overall I have 10 years of IT experience with 8 years of experience in COM, XML, XSL,
SQL Server 2000(with expertise in stored procedures, views,performance tuning,indexing skills).
This project aptly provides me to contribute and get involved and explore more avenues for
developing SQL skills in Java world.
