<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Hello list,</span>
<o:p></o:p></p>
<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Great to see
1.0 prod. Is out :)</span> <o:p></o:p></p>
<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Anyway,
currently i'm embedding ironpython to a web application. This gives us the
ability to write extension and modules in python. One requirement is the
possibility to pass arguments from the user context to the python enviroment.
Till now i've done this by adding or setting object to the globals.
Unfortunetly this approach isn't multi user suitable since the python
enviroment is static and the same instance for all users respectivly for all
sessions. So it could happen that a passed value of session2 overrides the
passed value of session1.</span><o:p></o:p></p>
<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>My thoughts:</span>
<o:p></o:p></p>
<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>1. Each
session has it's own python enviroment: this results in higher memory usage and
needs time each time a session loads it's python enviroment</span><o:p></o:p></p>
<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>2. The
arguments are not passed directly to the enviroment but to a session dependent
object: each script has to take care what args of what session will be taken</span><o:p></o:p></p>
<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>3. ? Is
there a possibility to pass args to a "ExecuteFile" context? I mean
my hosting application call's the method "executeFile" each time a
script will be executed and the passed args should be reachable ONLY in this
execution. </span><o:p></o:p></p>
<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>What is the
best solution to handle this challenge?</span> <o:p></o:p></p>
<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Thanks for
your hint's!</span> <o:p></o:p></p>
<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Regards,
bernd </span><o:p></o:p></p>
