Re: [IronPython] Callstack inspection
It's most likely that inspect won't work. But we certainly don't implement sys._getframe which will be necessary to crawl the stack. In the future we're going to look at both what we can do from our side and what could be done from the CLR side to make it easier to implement this feature - in other words this may be one of those features it takes us a while to get to. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Gary Stephenson Sent: Tuesday, August 15, 2006 3:51 PM To: Discussion of IronPython Subject: [IronPython] Callstack inspection I would like to adapt the following code to IronPython, but there appears to be no inspect module available.

[IronPython] dynamic types

Re: [IronPython] Debugging support PythonEngine
We have started doing some work for improving debugging as shown by the VSIP sample (http://blogs.msdn.com/aaronmar/archive/2006/02/16/533273.aspx). However, it still needs more work for it to be production-quality. By tools support, I was referring more to VSIP sample. We dont have a concrete timeline for when we will be able to improve it further. Btw, using your sample script below, in most cases, I am able to step from Python code into C# code in IronPython.dll if I hit F11 in VS. However, when IronPython.dll calls the method Add, we step into native code for a while before actually reaching the source code for Add. This looks like something we can fix by changing the debug information we generate. After doing this fix, it would be possible to mark IronPython.dll as library code (either using DebuggerNonUserCodeAttribute or through some other scheme), and be able to step from Python code into a Python method. x = 1 y = 2 def Add(a, b): return a + b z = Add(x, y) Stepping in here takes you to IronPython.dll source code, then native code, and then the source code for Add print z From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Kristof Wagemans Sent: Saturday, August 12, 2006 1:38 AM To: 'Discussion of IronPython' Subject: Re: [IronPython] Debugging support PythonEngine Thanks for the info. Its good to hear that there will be improvement possible in this area in the future. Although, the way I interpret your explanation, its not going to be anytime soon (or even this year), because you need enhancements to the underlying platform to make this possible. Ive experimented a bit with System.Diagnostics.DebuggerNonUserCodeAttribute to see if it wasnt possible to skip stepping into IronPython code. Unfortunately, the point where I get stuck in the assembly instructions is in generated code. I dont understand this part of the code well enough to know if its possible to make the debugger skip these lines. Maybe this is why you need the changes to the platform?

However, full support will need work in all parts of the tool chain including VS. Python local variables are implemented as normal MSIL variables (except in cases like closures). Hence, VS is able to display them. Currently, the best way to debug Python functions in VS while using PythonEngine would be to enable EngineOptions.ClrDebuggingEnable, open the PY file in VS and put a breakpoint where you want. Stepping in and out of Python functions will step you through methods in IronPython.dll .

Being able to debug makes writing and using python scripts a lot easier. Inside functions I can see not only the function parameters but also the newly defined local variables. Are these different from the global variables? I would have expected that the function locals are also stored inside a dictionary. Is it possible to step into python functions without getting into assembly instructions? This is very frustrating and degrades the debugging experience a lot. This is the more important issue for me. Im not going to be using global variables frequently, but mostly functions loaded in the PythonEngine that are called from C#.

The code generated by AssemblyBuilder, TypeBuilder, etc supports PDB debug information tracking for the methods, and so you will be able to set breakpoints in the code. However, it does not guarantee a perfect debugging experience. PythonEngine.ExecuteFile will use a dictionary for storing global variables, and these will not be visible because VS does not know about the dictionary. If you use PythonEngine.CreateOptimizedModule, most global variables are implemented using CLR statics, and so VS may be able to display them for you. Global variables added using an exec statement will still not be visible. If EngineOptions.ClrDebuggingEnabled is false, we will use System.Reflection.Emit.DynamicMethod. This does not support debug information tracking at all, and you will not even be able
