"Professional CMake" book suggest the following:
"Targets should build successfully with or without compiler support for precompiled headers. It
should be considered an optimization, not a requirement. In particular, do not explicitly include a
precompile header (e.g. stdafx.h) in the source code, let CMake force-include an automatically
generated precompile header on the compiler command line instead. This is more portable across
the major compilers and is likely to be easier to maintain. It will also avoid warnings being
generated from certain code checking tools like iwyu (include what you use)."
Therefore, removed the "#include <PreCompiled.h>" from sources, also
there is no need for the "#ifdef _PreComp_" anymore
* Harmonize FreeCAD with Python exception types
* Implement AbortException::getPyExceptionType() to avoid handling it in client code
* Remove catch block for plain C strings
In some circumstances, FileExceptions are constructed empty, then have a
filename assigned to them, but the error message in these scenarios is
left as the default "unknown" one, which is sometimes shown to users.
This change fixes that case to be consistent with instances that are
constructed with the filename.
add a special XMLAttributeError class to indicate an error when accessing a missing attribute
in PropertyContainer::Restore make error handling more flexible
remove QT_TRANSLATE_NOOP because of compiler warnings
mark _isReported as mutable to avoid removing const keyword from ReportException()
improve whitespaces
+ fix dangling pointers when fetching Python error text
+ initialize members in overloaded constructors of Exception class
+ implement assignment operator in sub-class
+ move to PyCXX API to simplify handling with reference counting and reading values from the dict
=========================
1. Enable automatic storing of information (function, file, line) when throwing the exception via macro:
Examples:
THROWM(Exception, "BSpline GeoId is out of bounds.")
THROWM(ValueError, "BSpline GeoId is out of bounds.")
THROW(AbortException)
Output:
a) Python Console (what()):
App.ActiveDocument.Sketch004.modifyBSplineKnotMultiplicity(16,3,0)
Traceback (most recent call last):
File "<input>", line 1, in <module>
Base.FreeCADError: FreeCAD exception thrown (BSpline GeoId is out of bounds.)
b) ReportException (report()):
Exception (Thu Apr 27 19:15:24 2017): BSpline GeoId is out of bounds. in bool Sketcher::SketchObject::modifyBSplineKnotMultiplicity(int, int, int) in src/Mod/Sketcher/App/SketchObject.cpp:4102
2. Extend the basic framework so as to allow more control over the mangling of the message introduced by the user, setting the basis to allow, where needed,
to preserve the original message while allowing full legacy behaviour.
3. Supporting FileDialog reporting as legacy
