Thanks for clarifying this.

Me bad. Ran the tests. All four passed.

Yes I realise running bpnn is pointless in regards to STM. But it did alert me
to the --stm option.
I ran the targetdemo and the error is:
[translation:ERROR] AssertionError: cast_ptr_to_adr(gcref) is a bad idea with
STM. Consider checking config.stm in <FunctionGraph of
(pypy.rpython.memory.gc.minimark:427)MiniMarkGC.post_setup at 0x98f82d4>
How is this fixed?
As a sidenote: I would like to get to a stage where I can take simple Haskell
STM examples and transcribe them into RPython. The first being the "Hello World
of STM" : the deposit/withdrawl programme.
I am looking at the targetdemo programme. The only place that references rstm is
for i in range(LENGTH):
add_at_end_of_chained_list(glob.anchor, i)
rstm.transaction_boundary()
print "thread done"
I don't see rstm.begin_transaction() being called. Is this implicit with when a
thread starts?
In general, what sort of feedback are you looking for at this stage?
Cheers,
Andrew
A bientôt,
Armin.
