用functools.partial跟踪

Question

I am working on a project that uses the trace module to trace the execution of code.
When I call trace.Trace(args).run(stuff) , stuff has to be either a code object or a string.

For now, I am building the function that I will be calling with calls to functools.partial . This part works exactly as I need it to.

However, when I get to the tracing part, I am not able to execute the trace with a functools.partial object. I can't use myFuncToolsPartialObject.func.func_name(args) because I can't guarantee that the function will be imported into the local scope. I can get around this with a call to import, but would rather not, at the moment (let's call it a personal preference).

Is there a way by which I can turn the functools.partial object into a code object for a proper call to trace?

I know I can ask for myFuncToolsPartialObject.func.func_code , but I'm wouldn't know how to call it on the required arguments

Answer 1

It turns out that trace has built-in support for just this use case. trace.Trace().runfunc(funcObject, *args) does exactly this.

From the docs :

runfunc(func, *args, **kwds)
Call func with the given arguments under control of the Trace object with the current tracing parameters.

这样行吗？

trace.Trace().run((lambda :partial_stuff(args)).func_code)
