[IronPython] How to do debugging for embedded usage

[Martin Maly]

Sorry for delayed response...

This is actually a valid bug in our codegen. The actual cause is that when we generate module-level code, we output void method and "return 1" tries to generate return code which would, on IL level, attempt to return non-void value from void function (that is in addition to the fact that we should generate syntax error in such case just like CPython does - "return statement outside of the function")

Now the reason you see it when you use RunFile and not with ExecuteFile, is just the difference between the implementations of RunFile and ExecuteFile.

Because i need to debug the embedded scripts, I changed from ExecuteFile(..) to RunFile(..), but the application will report "Common Language Runtime Detected an Invalid Program". I spent some time finding the reason. If i add statements such as "return False" "return 1" into the script, using RunFile(...) method will report the error, while executeFile works fine. The effect of using "IronPythonConsole scriptFilePath" just like using RunFile(...) method. I don't know why.

Because it it generated as a code snippet into the snippet assembly which doesn't have association with the source file and therefore the debugger cannot make the connection between the code and the source file.

I'm going to look into whether this could get changed/fixed.
