<p class=MsoNormal>We believe we know how to implement sys.settrace (we’d
hook it at the same place we hook our recursion checks today) but we haven’t
had time to get to it yet. Currently this is scheduled in our bug database
as 1.1 feature (although that may be subject to change) but it’s good to
note that we are seeing additional demand for these APIs. This will help
us prioritize our 1.1 work better. Hopefully we’ll be able to get
this in for 1.1 so it’ll be just a short term limitation. Thanks
for the input!<o:p></o:p></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>I
have been playing around with python debugging implementation for a while ,
allthough IronPython is a great effort on Python implementation , lacking
support for some cross platform standard libraries leeds to to serious
limitation in ironpython usage versus Cpython on short and long term.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>One
of the big missing is definitively the the sys.settrace standard function used
inside bdb.py and so inherited by python debugging tools on the planet as a
python standard debugging API entry point for years. <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>The
consequence to this is that trying to support IronPython in a python portable
debugging environment will fail(see below) …. And the only reminding
platform to make debugging happen will be the Visual Studio environment
…. Even the standard pdb.py which inherits bdb.py would not be usable on
short term then.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Providing
a descent implementation of those low level sys.function as it is already
available within JPython port would definitively provide more support of
IronPython by existing python debugger’s on the planet. <o:p></o:p></span></p>

xourse sys.settrace is part of the current sys implementation but when it comes
to get executed it’s disappointing :<o:p></o:p></span></p>
