           Summary: Ideally gyp generation would not have to happen at
                    sync time.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: levin at chromium.org

0. Ideally one could use widely used tools to sync and build webkit. (This requirement is simply about making things simple and reliable.)
1. I would like to be able to switch branches in git and be able to build.
2. I would not like my sync time to increase dramatically. (Based on various measurements, gyp generation may add between 5% to 40% overhead to a sync -- although the gyp generation time is consistent, the sync time varies)
3. I have a concern that having gyp generation happen on a developers machine after sync'ing may not work due to a slightly different machine configuration or a badly tested change in the gyp generation tool, etc. 

Now there is a concern that one could do a gyp change and not check in the generated files but we could have a test that runs to verify that the checked in version matches the generated version.
