pythonic parallel context

[Ruben Moor]

Hello,

I am using the bulletin board style system with embedded python and was very excited when I noticed the recent changes.

Now I have found some things not yet working as I expected (disregarding mistakes I may have made):

Code: Select all

while pc.working():
    metypefilename = pc.upkpyobj()
    features = pc.upkobj()

leads to the error:
neuron/nrn/src/nrnpython/nrnpy_p2h.cpp:504: Object* pickle2po(char*): Assertion `po' failed.

I am trying to unpack the arguments, provided along with the submit call. The arguments are of the type string, list of strings, string

Strings and scalars should still be unpacked with upkstr and upkscalar respectively.

features = pc.upkobj()

I assume that is a transcription typo and you really were using pc.upkpyobj()
So if the args are string, list of strings, string the sequence should be
s1 = pc.upkstr()
list = pc.upkpyobj()
s2 = pc.upkstr()
I need to add some error detection at a more reasonable level.

Hello,

unfortunately upkstr() did not work for me

Code: Select all

filename = pc.upkstr()

fails with "upkstr not enough arguments".

I worked around that with

Code: Select all

h('''strdef str1, str2
str1 = po.pc.upkstr(str1)
str2 = po.pc.upkstr(str2)
''')
filename = h.str1
features = h.str2

where I used 'submit' with a hoc-stub function as first argument and two strings as arguments.
This workaround does not work anymore once I use the pythonic version of 'submit'.
