Hi all, I've been working on some performance optimization to connectivity in order to make it able to operate in real time in more situations (very large designs or very slow computers).
The main changes are: (1) Threading of several parts of connectivity calculation that were previously not threaded (2) Moving the calculation of "dangling ends" into the connectivity system There is one caveat regarding (2): Currently, my branch does not update the dangling state of items while they are being moved (as is current KiCad behavior). Implementing exactly that behavior in this new code is not easy, because I haven't made a mechanism to run just the dangling state tests on a small subset of items. The current branch behavior will only update the items dangling indicators after the move is complete. Since I imagine some people will really want that behavior to stick around, I will think about a way to make it so. Despite this, I still want any input / testing that people are willing to give, as this set of changes can make quite a dramatic impact on large design performance in my testing. The code is on my github in conn_performance branch: https://github.com/craftyjon/kicad/tree/conn_performance [email protected]:craftyjon/kicad.git Thanks, -Jon
