As long as the behaviour you outline in [1] is consistent, then that means I should be able to use older Setup with newer setup.ini, yes? That will be useful for people who use the Time Machine. :) > * De-duplicate source archives > > Source archives which are identical[2] between x86 and x86_64 will be moved > to paths starting src/ in the release area. I'm not quite visualizing this, Do you mean there will be a new directory name 'src' that will be on the same level as 'x86' and 'x86_64' or will it be higher up the directory tree? It matters to me for the Time Machine as I'll need to be able to re-create the same directory hierarchy for each circa. It's a selectively automated process currently, but I need to know what symlink to place where. :) > Doing post-hoc de-duplication is unfortunate, but worthwhile given the > potential size saving in mirrors (see [3] et seq.), until cygport can be > taught how to make suitable source packages (which has several unresolved > issues, also discussed at [3], [4] et seq.). Will this be done en masse upon the next setup.ini build cycle, or over time as each new package is updated? Having a massive amount of "new" packages show up under a "new" directory named 'src' will be quite a lot for the mirrors to absorb all at once. For the Time Machine it might effectively be double as I have to maintain the old hierarchy as well as the new one (under the assumption that you'd apply the de-duplication retroactively). > * Migrate from setup.hint to pvr.hint in release area > > I also plan to migrate all remaining setup.hints to pvr.hints in the release > area (setup.hint in uploads have been automatically migrated since [5]). > > This should have no effect on the generated setup.ini, but enables some > complexity (some of which isn't implemented properly, see [6]) to be removed > from calm. > > [1] https://cygwin.com/ml/cygwin-apps/2017-12/msg00020.html > [2] my current implementation considers two archives identical if they have > an identical set of members, with identical contents.
