<div>I suggest this could be implemented in ThreadStateMapping like this:</div>

<div>(on top of that an implementation in PySystemState is straight forward)</div>

<div>&nbsp;</div>

<div>&nbsp;&nbsp;&nbsp; public static PyObject _current_frames() {<br/>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; @SuppressWarnings(&quot;unchecked&quot;)<br/>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Map.Entry&lt;Thread, ThreadState&gt;[] entries = new Map.Entry[globalThreadStates.size()];<br/>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; entries = globalThreadStates.entrySet().toArray(entries);<br/>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; PyObject elements[] = new PyObject[entries.length];<br/>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int pos = 0;<br/>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for (Map.Entry&lt;Thread, ThreadState&gt; entry: entries) {<br/>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; elements[pos++] = Py.newInteger(entry.getKey().getId());<br/>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; elements[pos++] = entry.getValue().frame;<br/>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<br/>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return new PyDictionary(elements);<br/>
&nbsp;&nbsp;&nbsp; }</div>

<div>&nbsp;</div>

<div class="gmail_default" style="color: rgb(0,0,0);">Hi Jython devs,</div>

<div class="gmail_default" style="color: rgb(0,0,0);">&nbsp;</div>

<div class="gmail_default" style="color: rgb(0,0,0);">I&#39;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...</div>

<div class="gmail_default" style="color: rgb(0,0,0);">&nbsp;</div>

<div class="gmail_default" style="color: rgb(0,0,0);">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).</div>

<div class="gmail_default" style="color: rgb(0,0,0);">&nbsp;</div>

<div class="gmail_default" style="color: rgb(0,0,0);">So, I&#39;d like to check how feasible it&#39;d be to have this support in Jython.</div>

<div class="gmail_default" style="color: rgb(0,0,0);">&nbsp;</div>

<div class="gmail_default" style="color: rgb(0,0,0);">Thanks,</div>
