Hello everyone,
I'm trying to get my head around PyPy (hoping maybe to participate in the
PyPy sprint at EuroPython), and following the getting-started guide on the
Web site. Translating pypy with the C backend worked with no problems on my
machine, but neither the JVM nor CLI backends work. (I tried both the
pypy-dist version and the SVN trunk.)
The stacktrace for the error is:
Traceback (most recent call last):

File "C:\Src\pypy\pypy\rpython\typesystem.py", line 153, in deref
assert isinstance(ootype.typeOf(obj), ootype.OOType)
AssertionError
When I evaluate 'obj' with the pdb, I get:
(Pdb+) p obj
<* fn CryptGenRandom>
As far as I understand, the problem happens because the 'posix' module under
Win32 implements 'urandom' by calling the native CryptGetRandom function
through rffi, but there is no mapping for this call under the JVM and CLI
backends.
What would be the proper way to fix this problem? (Or maybe I'm doing
something that's not supposed to work at all at this stage of the project?)
(Looks like my question should be at least partly answered by the "OO
backends" section of the document at
http://codespeak.net/pypy/dist/pypy/doc/rffi.html but unfortunately all it
says is "XXX to be written".)
Thanks in advance for your help!
Dmitry
