Hi all. I'm prepping for my first GHC commit, so I'm paying attention to all the details. I'm following the workflow described here http://hackage.haskell.org/trac/ghc/wiki/WorkingConventions/Git#Workflowwith... And I have a couple questions. Ultimately, I'm wondering if I'm doing something wrong or if those commands on that wiki page are either out-of-date or don't list some prerequisites. Question #1 When I run ./sync-all new The output shows lots of commits from the upstream repositories. * Is there a sync-all switch to avoid that somehow? * Is ./sync-all push going to push those? That'd be bad. Question #2 I omit dph from my working tree. Consequently, I think, sync-all in the validate tree chokes on some of the commands from that's wiki page's workflow (eg ./sync-all new). This choking prevents it from executing the command on the repos that come after dph in the list (ie the top-level GHC repo). Adding --no-dph doesn't seem to help here. Are there any known pitfalls here that I may have tripped into? Or perhaps some flags I could add to my command lines? Else, it seems that adding dph to my working repo is necessary for validation with this suggested workflow. Thank you for your time.
