<p class=MsoNormal><span style='color:#1F497D'>Thanks for the quick responses,
Jean-Paul & Itamar.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>It looks like turning my app
into a twistd plugin seems to be the preferred method (well, quashing bugs quickly
and permanently with Unit Tests is obviously the preferred method :o) !) <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>Itamar, <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Courier New"'>>When
using twistd or trial, you can simply use the debug command-line<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Courier New"'>>option
for that (-b). Without those,<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Courier New"'>>twisted.python.failure.setDebugMode(True)
or something, I forget the exact<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Courier New"'>>invocation.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>There is a twisted.python.failure.startDebugMode(),
but it doesn’t seem to stop the reactor on exceptions (I’m not directly
using Deferred’s, so maybe that’s the reason).<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>I’m mostly using Twisted
for it’s robust Networking protocols (ok, and a bit of scheduling), and I
can’t say enough good things about how well it works.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>I also know Twisted has many
more parts to it than the small subset I’m using, but it seems
unfortunate to me that including any part of Twisted in a program means that
all exceptions are trapped –whether or not the exception has anything to
do with Twisted.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>Regular Python (sans Twisted)
doesn’t trap exceptions, but I’m sure there are many good reasons
for doing so with Twisted (you don’t have to list them – I’m
not being facetious). I just think it would be useful to be able to set a
flag somewhere to stop this behaviour. <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>I will definitely remove this
after, but adding a ‘raise’ statement to the except clause of the
RunUntilCurrent method of ReactorBase in base.py seems to do exactly what I
want. <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>…would zero percent be on the
high side for the chances of having a Twisted developer make some sort of flag
available that would turn this on? (or equivalent functionality)<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>…just askin…<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>Thanks again for your
help/advice guys,<o:p></o:p></span></p>
