Hello!
Greetings.
I am trying to contribute to commons.math .
Thanks!
What would you like to work on?
I am annotating the library which can help the plugabble type
checker
which
is Checker Framework,which can help in dealing with run time
errors. I am
currently trying to build the environment and read the source code
,there
after understanding it, annotate it so that Checker
Framework(particularly
Index Checker can help in finding run time ArrayOutOfBound errors).
What is the added value of this tool wrt "SpotBugs"?
CheckerFramework is pluggable type System. It gives the restrictive
usage
to code and thus prevents errors. For example,
String op(Data in) {
return “transform: ” + in.getF();
}
String s=op(null)
It will compile,but generate NullpointerExcetption,but using
String op( @NonNull Data in{
...
}
String s=op(null) //This will result in error.
Thus it adds following values to code as per my knowledge
* Find
*bugs in programs*
** *Guarantee absence of errors
* Improves Documentation
*Aid compilers,optimizers and analysis tools
* Reduce number of run time checks.
Looks interesting...
This all I have inferred from its manual. Apart from it I am planning
to
appy for GSOC with CheckerFramework Organisation. Being new to open
source
projects ,GSOC can provide me with exposure and zeal to work on open
source.
Please note that parts of "Commons Math" are being refactored
into smaller and more focused components.
Depending on your goals, it may be worth look at them first.
Can you please provide me the link of this or where could I find
refactored
code.
They are in their respective "git" repositories:
https://git1-us-west.apache.org/repos/asf?p=commons-rng.git
https://git1-us-west.apache.org/repos/asf?p=commons-numbers.git
https://git1-us-west.apache.org/repos/asf?p=commons-statistics.git
and (mirrored) on GitHub:
https://github.com/apache/commons-rng
See also info on the component's dedicated web site:
http://commons.apache.org/rng
(and similar for the other components).

So I cloned the project and
opened it in eclipse. It downloaded all the related required jar
files,but
failed to download commons.number
So I tried to download from official page from
apache.commons.numbers
But it showed there are no official releases but it is being used
in
apache
commons.math
Indeed, "maven" will download those dependencies from this
repository:
https://repository.apache.org/content/repositories/snapshots
/org/apache/commons/
Note that "Commons Numbers" is comprised of several
modules/artefacts/JARs.
Please help me out with this ,I am new to open source
contribution.
Welcome.
Don't hesitate to ask more questions; whne you post to this list,
please add a prefix on the Subject: line that identifies the
component concerned with the message (like I've done now)
Thank You so much for help. I have only heard about unity in open
source
community,but first time felt it.
If you have any suggestions for me,please free to share.
If not done already, you could have a look at the bug-tracking
system.
The following list issues and ongoing work related to Commons Math
and
its spin-offs:
https://issues.apache.org/jira/projects/MATH
https://issues.apache.org/jira/projects/NUMBERS
https://issues.apache.org/jira/projects/RNG
https://issues.apache.org/jira/projects/STATISTICS

Gilles
