pypq in RPython
by Nick Fankhauser Nov. 13, 2012

Nov. 13, 2012

Hi! I'm trying to compile one of my python applications using "translate.py". Because the application needs access to postgreSQL, it's using pypq. The application runs fine in python, and pypy as well. Using the error messages from translate.py, I made a lot of changes to my program to make it as much RPython as I can make it. But even after changing the code many, many times, I never get past the following error message. It's from pypq and I'm not sure what command in my application … [View More]triggers the error, but by looking at the pypq source, I assume it's from a pypq-"commit" command. My questions are: - Is it even possible to use pypq in RPython? - If not, is there any other postgreSQL adapter that works? - Is there example-code for connecting to a database in RPython? - Is it possible to find the command in my application that triggered the error? Thanks! This is the error message: [translation:ERROR] Error: [translation:ERROR] Traceback (most recent call last): [translation:ERROR] File "/opt/pypy_source/pypy/translator/goal/translate.py", line 303, in main [translation:ERROR] drv.proceed(goals) [translation:ERROR] File "/opt/pypy_source/pypy/translator/driver.py", line 771, in proceed [translation:ERROR] return self._execute(goals, task_skip = self._maybe_skip()) [translation:ERROR] File "/opt/pypy_source/pypy/translator/tool/taskengine.py", line 116, in _execute [translation:ERROR] res = self._do(goal, taskcallable, *args, **kwds) [translation:ERROR] File "/opt/pypy_source/pypy/translator/driver.py", line 283, in _do [translation:ERROR] res = func() [translation:ERROR] File "/opt/pypy_source/pypy/translator/driver.py", line 319, in task_annotate [translation:ERROR] s = annotator.build_types(self.entry_point, self.inputtypes) [translation:ERROR] File "/opt/pypy_source/pypy/annotation/annrpython.py", line 89, in build_types [translation:ERROR] return self.build_graph_types(flowgraph, inputcells, complete_now=complete_now) [translation:ERROR] File "/opt/pypy_source/pypy/annotation/annrpython.py", line 142, in build_graph_types [translation:ERROR] self.complete() [translation:ERROR] File "/opt/pypy_source/pypy/annotation/annrpython.py", line 195, in complete [translation:ERROR] self.processblock(graph, block) [translation:ERROR] File "/opt/pypy_source/pypy/annotation/annrpython.py", line 340, in processblock [translation:ERROR] self.flowin(graph, block) [translation:ERROR] File "/opt/pypy_source/pypy/annotation/annrpython.py", line 399, in flowin [translation:ERROR] self.consider_op(block, i) [translation:ERROR] File "/opt/pypy_source/pypy/annotation/annrpython.py", line 577, in consider_op [translation:ERROR] argcells = [self.binding(a) for a in op.args] [translation:ERROR] File "/opt/pypy_source/pypy/annotation/annrpython.py", line 238, in binding [translation:ERROR] return self.bookkeeper.immutableconstant(arg) [translation:ERROR] File "/opt/pypy_source/pypy/annotation/bookkeeper.py", line 314, in immutableconstant [translation:ERROR] return self.immutablevalue(const.value) [translation:ERROR] File "/opt/pypy_source/pypy/annotation/bookkeeper.py", line 461, in immutablevalue [translation:ERROR] result = SomePBC([self.getdesc(x)]) [translation:ERROR] File "/opt/pypy_source/pypy/annotation/bookkeeper.py", line 535, in getdesc [translation:ERROR] raise Exception("%s: %r" % (msg, pyobj)) [translation:ERROR] Exception: object with a __call__ is not RPython: <_ctypes.function.CFuncPtrFast object at 0x000000001f11b6a0> [translation:ERROR] Processing block: [translation:ERROR] block@9 is a <class 'pypy.objspace.flow.flowcontext.SpamBlock'> [translation:ERROR] in (pypq.connection:68)Connection._get_transaction_status [translation:ERROR] containing the following operations: [translation:ERROR] v0 = getattr(self_0, ('_db')) [translation:ERROR] v1 = simple_call((CFuncPtrFast PQtransactionStatus), v0) [translation:ERROR] --end-- [translation] start debugger... > /opt/pypy_source/pypy/annotation/bookkeeper.py(535)getdesc() -> raise Exception("%s: %r" % (msg, pyobj)) My program is structured like this in respect to database access: database_connection=pypq.connect('connect_string') def foo(): dbc=database_connection.cursor() dbc.execute('SELECT what,val FROM some_table') some_dict={} for w,v in dbc.fetchall(): some_dict[w]=v dbc.close() return some_dict def maincode(args): Some code, which call foo, among other functions. def target(driver,args): return maincode,None [View Less]

Any publications regarding PyPy / trace-based JIT compiler?
by Michael Sioutis Nov. 11, 2012

Nov. 11, 2012

Dear PyPy team, I am in the process of writing a paper that will target some AI conference, and I would like to ask if there are any relevant publications of yours or in general that showcase the possible advantages of trace-based JIT compilation over method-based JIT compilation or static compilation. I just want to use 2 or 3 of them as references when I explain why my implementation is more scalable and robust when compared to some C/C++/Java implementations (appart from different data … [View More]

Re: [pypy-dev] Is cffi fixed for win32?

Hi Matti, hi all, On Tue, Nov 6, 2012 at 10:54 PM, Matti Picus <matti.picus(a)gmail.com> wrote: > Are there anymore failing win32 tests for cffi, or is cffi fully supported > for windows now? There are no failure left from test_c, and running (manually) the full test suite from "cffi/testing" mostly passes now. The remaining issues don't show any serious problem. So CFFI seems to work on PyPy on Windows now :-) A bientôt, Armin.

Excessive blocking in multiprocessing?

Nov. 3, 2012

Hello, As part of an introductory course of computational neuroscience, we learned the basics of NLTK to analyze wikileaks. On my own, I tried PyPy 1.9 (under Ubuntu 12.04 64-bits) and a simple MapReduce scheme as an attempt to improve performance. There are 14266 files under "cable", adding up to 1.2GB. It can be downloaded as a 30MB compressed 7z here: http://www.dc.uba.ar/materias/incc/practicas/p2/nltk/wikis.7z The results are: $ time python test_mapreduce.py 170686 python … [View More]
