upgrade: move descriptions and selection logic in individual classes Our goal here is to get top level definition for all the format variants. Having them defined outside of the function enabled other users of that logic. They are two keys components of a format variant: 1) the name and various descriptions of its effect, 2) the code that checks if the repo is using this variant and if the config enables it. That second items make us pick a class-based approach, since different variants requires different code (even if in practice, many can reuse the same logic). Each variants define its own class that is then used like a singleton. The class-based approach also clarify the definitions part a bit since each are simple assignment in an indented block. The 'fromdefault' and 'fromconfig' are respectively replaced by a class attribute and a method to be called at the one place where "fromconfig" matters. Overall, they are many viable approach for this, but this is the one I picked.

#require test-repo

Set vars:

  $ . "$TESTDIR/helpers-testrepo.sh"
  $ CONTRIBDIR="$TESTDIR/../contrib"

Prepare repo:

  $ hg init

  $ echo this is file a > a
  $ hg add a
  $ hg commit -m first

  $ echo adding to file a >> a
  $ hg commit -m second

  $ echo adding more to file a >> a
  $ hg commit -m third

  $ hg up -r 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo merge-this >> a
  $ hg commit -m merge-able
  created new head

  $ hg up -r 2
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
