Matthias Koefferlein 9c0e94e63c WIP: Allowing extension (mixin) classes 
Needed to represent QIODeviceBase as a second base class for
QIOdevice, QFile etc. Additional base classes are supported but
in a rather limited way. They only contribute constants like enums.
No methods can be provided this way (a limitation of the method
enumeration scheme which only supports one base classe)

Matthias Koefferlein 2fee924103 Updated the solution 2021-07-15 23:39:02 +02:00
Matthias Koefferlein 2b447854f9 Enhanced matching of blackbox/pin ambiguities 
Previously: matching of blackbox pins was enforced
by using pin names for passive nets in the compare.
Problem: no match was achieved when pins are not
named or not named consistently.

In this case, it's desirable to treat them as
ambiguous.

The new solution is to let the ambiguity resolver handle
that using an extended definition of the net names:
it will take the pin name into account if an unnamed net
is attached to a pin.

In addition, net ambiguities are projected to pin
equivalence now. This also will propagate symmetry
through nested blocks (dbNetlistCompareTests:20_BusLikeConnections).

Matthias Koefferlein c24c0933bf Bugfix: blackbox mode/abstract pins 
Abstract pins are created when pins are not attached to any or only to passive nets
(passive nets are those without device terminals or subcircuit pins).

1. Such pins were treated swappable. Now named pins will not be treated
   swappable but are mapped by name. This enables blackbox models where
   the pins are labelled and must correspond to schematic pins.
2. A bug was present which lead to incorrect handling of abstract
   nets in net compare.

#730: providing a new Qt module named QtUiTools for QUiLoader class s… (#735) 
* #730: providing a new Qt module named QtUiTools for QUiLoader class support.

* Fixed a compile error on Mac

* Added QtUiTools to some more places

* Fixed a linker issue in the QtUiTools Python lib

* On occasion fixed a infinite recursion problem in the debugger

The recursion happened because by mistake I instantiated a
QApplication inside an in-application Python script. This
crashed the debugger due to infinite recursion. This is not
a real use case but to prevent similar issues, a recursion
sentinel was added.

* Removed QCoreApplication#notify from script bindings

Reasoning: "notify" made standalone scripts using QApplication and
QUiLoader virtually impossible.

Problem description:
- When a QApplication object is instantiated, e.g. in Python, the Qt binding
  will install reimplementation hooks as the object may be dynamically
  extended.
- A notify is virtual this means the *every* "notify" call in the application
  is routed through the interpreter.
- For one thing this will slow down the application
- But as "notify" is called a zillion times this has more than this side effect.
- Specifically "notify" is called from within the QWidget constructor to
  indicate a new widget. Then, if a QDialog for example is instatiated, it's
  base class constructor will call "notify" when the object isn't ready yet.
- This has another severe side effect: as the object isn't ready yet, it gets
  registered in the Python space with the wrong class and QDialog is not visible
  as such.

To mitigate these problems, the most efficient solution is to disable "notify"
in general. There is hardly any use case in a script environment (in C++,
apart from hacking the only reasonable use case is exception handling, but
this does not apply to scripts). For providing the call functionality of
"notify" you should better use "postEvent" or "sendEvent" anyway.

So farewell QCoreApplication.notify ...

* Fixed python test for QtUiTools module

* Fixed UiTools test on Qt4 - QUiLoader needs an application object

Reduce risk of DRC polygon split artefacts in deep mode (#722) 
* Fixed a segfault with simple 'klayout -v'

* is_halfmanhattan polygon predicate, confine polygon splitting to halfmanhattan

Splitting any-angle polygons for area reduction in the
deep processor creates a risk of introducing grid-snap
artefacts. Hence we avoid this.

Issue 718 (#719) 
* WIP: first part of fix - generation of hole cutlines

First problem was that hole cutlines got extended
over the whole length and sometimes lead to coincident
edges which are difficult to resolve for the polygon
cutter.

* Refined solution, fixed #718

- disabled elaborate hole insertion procedure for now as the
  performance impact has to be assessed yet and the new scheme
  will break many tests
- stricter rejection of ambiguous configurations in the polygon cutter
- fallback is boolean AND now since there is no need to re-invoke the
  polygon cutter (we can't do so as we made it more strict).
  Performance-wise we replace a merge by an AND step which may even be
  faster the output is smaller and the polygon cutter does not need
  to be re-invoked.

* Compatibility with other STLs
