Subject Re: [DISCUSSION]: Integrating SureLogic into Hadoop
Date Fri, 07 May 2010 23:35:11 GMT
Hi Cos,

This looks great, and I'm excited to have more ways of finding these tricky
bugs. Are there any examples of bugs found already by these techniques?

The one concern I have about the proposal is with this:
> SureLogic analysis is going to be included to the test-patch process. This
said new patches are required not to raise SureLogic warnings level (similar
to the requirements about FindBugs or javac).

This is slightly worrisome since the SureLogic license is only available to
committers. For non-committers, I think this may prove to be difficult since
they won't have any local means of checking for warnings and verifying that
they've fixed them.
