The variables in the common settings struct are only updated on
save, so Python must use the ones from Pgm to get its values.
This does lead to the observation that Python's changes to the
variables do affect KiCad (they can break resolvers). So apparently
it can mess with us but we can't mess with it easily.
Also, improve the environment variable tracing infrastructure to capture
more changes.
Before this, the environment variables inside Python wouldn't reflect
the updates to them made after the interpreter was started in Pcbnew.
This will call into Python and set the variables when they are changed,
since Python can't synchronize itself when running in an embedded
interpreter.
Fixes https://gitlab.com/kicad/code/kicad/issues/5071
Always check the return value of PyRun_SimpleString() for errors when a
Python script is run and show an error message rather than fail silently.
Enable Python interpreter I/O redirection in debug builds so that script
string errors will be shown when PyRun_SimpleString() is called.
Do not call PyErr_Print() after a PyRun_SimpleString() call failure. It
doesn't do anything useful.
Do not call Py_Finalize() after a PyRun_SimpleString() call failure. It
seems to cause Pcbnew to crash.
*) Extend SWIG support deeper into the BOARD class.
*) Move swig *.i files into a directory identified for SWIG, in preparation
for a parallel universe involving Phoenix's SIP.
*) Move swig files which will be common to both eeschema and pcbnew into
common/swig.
*) Sketch out a "common" python module, and plan on dovetailing that into a
libkicad_shared.{dll,so}
*) Add common/swig/ki_exceptions.i and define a macro HANDLE_EXCEPTIONS()
which is to be applied to any function which needs C++ to python
exception translation.
*) Move the test for SWIG tool into top level CMakeLists.txt file for use
in all python modules beyond pcbnew, i.e. eeschema and common.
*) Add SWIG_MODULE_pcbnew_EXTRA_DEPS which generates a better Makefile, one
which rebuilds the swig generated *.cxx file when one of its dependencies
change.
*) Re-architect the board.i file so that it can be split into multiple *.i
files easily.
*) Make some KIWAY from python progress, in preparation for Modular KiCad
phase III.
