Hi Richard,
Thanks for your reply.
I tried code suggested by you
t = stackless.current
import traceback
traceback.print_stack(t.frame)
The above code only provides me a call stack of the thread I am actually in.
Let me elaborate my problem a little more:
- I have n no. of tasklets which I monitor from an external thread.
- The way you have suggested gives me the call stack of the external thread.
In my external thread I have a reference to all the currently running tasklets
and I want to get a call stack for each of these running tasklets.
When I try to get the call stack for any tasklet other than the current one, I
get the following exception:
<Job 107C5928 on <tavant.publisher.Publisher object at 0x10775F68>>I have given
the following console statements in my code that leads to the above error:
ALIVE True
Frame <stackless.cframe object at 0x10AEDF58>
Traceback (most recent call last):
File "..\..\..\Assets\InGame\Gameplay\Scripts\Debug\pydevd_comm.py", line
897,
in doIt
print("callstack: ",traceback.extract_stack(selectedJob.frame))
File "..\..\..\Assets\InGame\Gameplay\Scripts\lib\traceback.py", line 328, in
extract_stack
lineno = f.f_lineno
AttributeError: 'stackless.cframe' object has no attribute 'f_lineno'
print(selectedJob)
print("ALIVE", selectedJob.alive)
print("Frame", selectedJob.frame)
print("callstack: ",traceback.extract_stack(selectedJob.frame))
Note: selectedJob above is an object of a Job class and we have inherited Job
class from a stackless.tasklet.
Thanks and Regards,
Hussain Bohra

Hi All,
We are using stackless python for our application development.
We are creating many tasklets in our?application, I am developing an
application
to monitor?these tasklets.
I am able to get and display all the running tasklets in the UI. But I also
want
to?display the callstack for each tasklet. I am not able to generate a
callstack?for these tasklets.
Just FYI: We can determine callstack of running threads in Java.
Can any one please let me know?if there is a way out ?
Thanks and Regards,
Hussain Bohra
