The first issue is probably the same that IL offset 0 does not
have any debug information. Calling the delegate “add” steps into a
DynamicMethod which confuses VS. A workaround for now is to add this statement before
creating the PythonEngine. IronPython.Compiler.Options.GenerateDynamicMethods
= false; This disabled the use of DynamicMethods altogether and will
instead use AssemblyBuilder. This is not generally recommended or supported since
you are going to leak memory since AssemblyBuilder memory cannot be reclaimed.
However, VS seems to be better able to deal with AssemblyBuilder during stepping,
and it might be good enough for you. This is a case where we will would need to
teach the tool (VS) to handle DynamicMethods differently than it currently
does. From:

Behalf Of Kristof Wagemans It’s good to hear that it’s fixable. But, off course,
here’s the next one J. With the same little script: x = 1 y = 2 def Add(a, b): x = a + b return x z = Add(x, y) print z And the following C# code: EngineOptions options = new EngineOptions(); options.ClrDebuggingEnabled = true; PythonEngine _pe = new PythonEngine(options); delegate int Add(int a, int b); _pe.ExecuteFile(@" script path "); Add add = _pe.EvaluateAs<Add>("Add"); int var1 = add(2, 3); int var2 = add(3, 4); The following happens: (I use a release version of Ironpython (RC2). There are no debug
symbols present, so that I don’t step into the engine code.) I step into ExecuteFile (F11) and get into native code. After a few
lines of native code, I can go back to the source code view and I’m in
the Python script file. Maybe this is a similar issue as with stepping into a
function? Next, I get a delegate to the Python Add function. The first time I
step into the add delegate I get the stepping into a function problem and then
I’m inside the function. But, when I try to step into the next add
delegate this doesn’t work anymore: the line is marked in green in Visual
Studio and I remain in the C# code. The next step into command resumes on the
next line in the C# code. I can’t see a reason why it would fail with the
next add. Setting a breakpoint in the Python function stops the execution at
that point in both cases. From:

Behalf Of Shri Borde I have opened this bug - http://www.codeplex.com/WorkItem/View.aspx?ProjectName=IronPython&WorkItemId=2248
- to track the issue with stepping in. We are not emitting any line number
information for IL offset 0. |
