Like all other NetBeans development teams, Profiler team has to use mercurial (hg) from February. Since the traffic and number of broken builds in main NetBeans repository is alarming, we asked our release engineering to set up separate NetBeans Profiler mercurial repository called profiler-main and continuous build. We update profiler-main once a day from main-golden. Main-golden is updated from main only if it can be built successfully and the basic set of tests passed. This way we can work on relatively stable build of NetBeans. When fixing bugs we first push changeset to profiler-main and corresponding bug is closed as FIXED in IssueZilla, than the fix is propagated to main and from main finally to main-golden. Corresponding issue is automatically updated with information about public build. If you don't want to wait for fix to be propagated to main-golden you can download NetBeans with fix from our continuous build.
