copies: do not track backward copies, only renames (issue3739) The inverse of a rename is a rename, but the inverse of a copy is not a copy. Presenting it as such -- in particular, stuffing it into the same dict as real copies -- causes bugs because other code starts believing the inverse copies are real. The only test whose output changes is test-mv-cp-st-diff.t. When a backwards status -C command is run where a copy is involved, the inverse copy (which was hitherto presented as a real copy) is no longer displayed. Keeping track of inverse copies is useful in some situations -- composability of diffs, for example, since adding "a" followed by an inverse copy "b" to "a" is equivalent to a rename "b" to "a". However, representing them would require a more complex data structure than the same dict in which real copies are also stored.

basic test for hg debugrebuildstate

  $ hg init repo
  $ cd repo

  $ touch foo bar
  $ hg ci -Am 'add foo bar'
  adding bar
  adding foo

  $ touch baz
  $ hg add baz
  $ hg rm bar

  $ hg debugrebuildstate

state dump after

  $ hg debugstate --nodates | sort
  n 644         -1 bar
  n 644         -1 foo

status

  $ hg st -A
  ! bar
  ? baz
  C foo

  $ cd ..
