New submission from Antoine Pitrou <[email protected]>:
In the following code, the original traceback attached to the exception thrown
into the generator is ignored:
def gen():
try:
yield
except:
raise
g = gen()
try:
1/0
except ZeroDivisionError as v:
g.throw(v)
But if you replace the last line with:
g.throw(type(v), v, v.__traceback__)
then the original traceback gets appended.
g.throw() should have fetched the __traceback__ attribute by itself.
