Here's the next step then: - I am going to update HowToUseConcurrencyAnalysisTools wiki with the details on how contributors can get the license - it seems we are ready to add up promisses.jar to the list of our dependencies (patches are already available for HDFS and MR) Shall we have

I agree, thanks for looking into it, and this sounds entirely reasonable. I imagine a great number of the contributors are committers on some apache project or another (if not Hadoop itself) so we'll only need to make special exemptions occasionally. -Todd On Fri, May 14, 2010 at 1:19 PM, Konstan

This is good news! I found SureLogic stack useful for finding bugs. It was especially helpful in detecting synchronization issues. Good that the licensing issues are cleared out. Thanks, Cos. --Konstantin On 5/14/2010 12:59 PM, Konstantin Boudnik wrote: Here's an update from SureLogic on the li

Here's an update from SureLogic on the licensing of the software to the broader contributors community. 1) For now we should be able to use 'committers' license (the one we already have) to share with contributors on per case basis (a contributor needs to ask for it and after a considerati

This is very valid concern Todd. I am talking with SureLogic at the moment to find out if they will be willing to provide the license to all Hadoop contributors. On the other hand not including such type of validation into standard patch validation process poses a danger of code degradation as ti

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

[DISCUSSION]: Integrating SureLogic into Hadoop

2010-05-05 Thread Konstantin Boudnik
Hello. As some of you might know we have the license for great concurrency analysis software from SureLogic. SureLogic engineers gave some run for HDFS, MR, and Zookeeper code at the end of last year. The tools seem very promising and supposedly bring us the value (linked from the page below). P
