Re: Support for sys._current_frames

I suggest this could be implemented in ThreadStateMapping like this:

(on top of that an implementation in PySystemState is straight forward)

public static PyObject _current_frames() {

@SuppressWarnings("unchecked")

Map.Entry<Thread, ThreadState>[] entries = new Map.Entry[globalThreadStates.size()];

entries = globalThreadStates.entrySet().toArray(entries);

PyObject elements[] = new PyObject[entries.length];

int pos = 0;

for (Map.Entry<Thread, ThreadState> entry: entries) {

elements[pos++] = Py.newInteger(entry.getKey().getId());

elements[pos++] = entry.getValue().frame;

}

return new PyDictionary(elements);

}

Opinions?

Betreff: [Jython-dev] Support for sys._current_frames

Hi Jython devs,

I've just updated the PyDev debugger to drop support for older Python versions and it seems I ended up breaking debugging in the current Jython version because of it...

The issue is that PyDev now requires sys._current_frames to be implemented by the interpreter (available since Python 2.5), but it seems this is not available for Jython -- this is needed so that the debugger can be faster (i.e.: it runs with untraced frames until some breakpoint is actually added -- at that point it gets the current frames and sets the tracing in them).

So, I'd like to check how feasible it'd be to have this support in Jython.

Thanks,

Fabio
