I just have a comment about the known issues. Not sure if it makes sense to invest effort into addressing these within current design, as we want to stop using custom EWS code and move as much as possible to Buildbot. The stack that EWS is currently built on is very different from anything else we use, so it's difficult to maintain. - Alexey > I am open to suggestions. > > Dan > _______________________________________________ > webkit-dev mailing list > webkit-dev@lists.webkit.org > https://lists.webkit.org/mailman/listinfo/webkit-dev
