This also removes the GROUP/UNGROUP-specific undo actions.
This also fixes a bunch of undo bugs when duplicating
group members, creating pins, etc.
This also fixes some undo bugs when dividing wires etc.
This also fixes some bugs with new sch items not
being created within an entered group.
Make the VIEW* parameter const. Since PCB_TEXT does a null-check,
it's not very clear if this can ever be null (and if it is,
why don't the other VIEW_ITEMs check?), so don't make them
all references too at this time.
Also dereference a few pointers a bit earlier to make non-null
promises sooner rather than later.
Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
Currently, new global or local net labels are auto-filled with the
net name if the wire is driven by a global or local label. This
currently happens recursively within SCH_LINE. This fix moves this
to determining the driver from the connectivity graph, and removes
the determination from the SCH_LINE code where it does not belong.
Prior to this change, the schematic connectivity was updated any time a
change was made to a connectable object. Now the connectivity is only
updated when an object change actually affects the connectivity. Other
properties like line width, fill type, custom fonts, etc. will not cause
the connectivity graph to be rebuilt.
The SCH_COMMIT flag SKIP_CONNECTIVITY has been removed. All schematic
objects can test if they are connectable and if there have been changes
to any connection properties that require a connectivity rebuild.
Remove duplicate rebuild connectivity calls from editor control tool.
This was causing the tangling end test to get called four times on every
undo and redo action because the dangling end test is already called in
the connectivity graph calculation code.
Update connectivity when changing label names which fixes an unreported
connectivity bug.
Avoid O(N^2) by spatial sorting, don't run checks if the bounding boxes
don't overlap.
A second copy is ordered by type to help classes that only want to check
a few types having to walk the whole list.
Fixes:
* Various special cases around junctions on pins and dragging.
* Some rotations of endpoints resulting in a 45 degree rotate.
* Some cases where it was possible to get a line with neither
endpoint selected, and also substractive unselecting only one of two
selected endpoints unselecting both.
* Use line midpoint for sorting. Start and endpoints aren't
consistent in the order they appear on the X or Y axis. So,
we need to use the midpoint for our position for consistent
sorting when dragging groups of parallel lines where some
have the start and end reversed.
Other:
* Rename TEMP_SELECTED TO SELECTED_BY_DRAG. This is the actual meaning
of the flag, and should reduce confusion as
to when it should be used.
* Move usage of TEMP_SELECTED as an algorithmic mark to CANDIDATE
instead.
* Fix mistaken clearing of START_POINT and ENDPOINT.
* Move endpoint setting and clearing out of narrowSelection, and into
selectPoint and selectMultiple.
* Don't show dangling end warnings on new lines
