#785 assigned defect

Tree modifications have uncontrolled impact on groups

Moving subtrees

For normal groups the impact is small in most cases:

  • moving one of the 2 childs at the top-level of a group
    ⇒ does also move group information
if a majority of the group is moved→ ok
if only a minority of the group is moved→ not ok

For keeled groups (see #735) the impact depends on the orientation of the group:

  • if the group was keeled to (old) brother of moved subtree
    ⇒ afterwards it's either keeled
    • to (new) brother or
    • to moved subtree itself,
    i.e. completely wrong anyway :-(
  • if the group was keeled to the moved subtree
    ⇒ no impact :-)


  • basic operation swap_assymetric() causes similar problems to those described for Moving subtrees above (did not inspect details yet)
