[IronPython] HostCodeHeap leakage?

[Dino Viehland]

Yep, DebugMode is the same as -X:Debug.  In general I'd suggest making this configurable somehow and only turn it on if you're actually debugging.  It's unfortunate that we can't offer both debugging & collectability but right now that's simply a limitation of the CLR and/or our lack of a separate VS debug engine which can debug Python code.

Im running using the engine from a hosting app.
We have these lines in the startup:
ScriptRuntimeSetup setup = new ScriptRuntimeSetup();
setup.DebugMode = true;

ScriptRuntime runtime = Python.CreateRuntime(setup.Options);


engine = runtime.GetEngine("py");


Is this is the same like -X:Debug?
You reckon this could be the cause?

My guess is that's code in the JIT heap that's building up but I'm not 100% certain.  How is your code being executed?  Do you have the debug option (-D or -X:Debug) enabled?  To support debug mode we need to produce uncollectible code which could be building up.

I am trying to find a memory/"performance" leak in an Ipy application.

Using WINDBG (!eeheap -loader), we noticed the that the LoaderHeap is getting bigger (150MB increase per day). From the !eeheap output it seems that the increase is due to HostCodeHeap (objects?).

As I understand these objects might be created by Ipy infra, is that right?

Is there anyway I can get more info on their content, or prevent them from growing?

Thanks
