pypy translation error

Greetings, I've been working on getting pypy to build on Solaris 11 Express using gcc 4.5. I could use some help deciphering the following error I encountered during translation using "python2.6 translate.py -Ojit": [translation:ERROR] Error: [translation:ERROR] Traceback (most recent call last): [translation:ERROR] File "translate.py", line 308, in main [translation:ERROR] drv.proceed(goals) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/translator/driver.py", … [View More]line 809, in proceed [translation:ERROR] return self._execute(goals, task_skip = self._maybe_skip()) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/translator/tool/taskengine.py", line 116, in _execute [translation:ERROR] res = self._do(goal, taskcallable, *args, **kwds) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/translator/driver.py", line 286, in _do [translation:ERROR] res = func() [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/translator/driver.py", line 323, in task_annotate [translation:ERROR] s = annotator.build_types(self.entry_point, self.inputtypes) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/annotation/annrpython.py", line 103, in build_types [translation:ERROR] return self.build_graph_types(flowgraph, inputcells, complete_now=complete_now) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/annotation/annrpython.py", line 194, in build_graph_types [translation:ERROR] self.complete() [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/annotation/annrpython.py", line 250, in complete [translation:ERROR] self.processblock(graph, block) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/annotation/annrpython.py", line 448, in processblock [translation:ERROR] self.flowin(graph, block) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/annotation/annrpython.py", line 508, in flowin [translation:ERROR] self.consider_op(block.operations[i]) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/annotation/annrpython.py", line 710, in consider_op [translation:ERROR] raise_nicer_exception(op, str(graph)) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/annotation/annrpython.py", line 707, in consider_op [translation:ERROR] resultcell = consider_meth(*argcells) [translation:ERROR] File "<4151-codegen /export/home/swalker/devel/pypy/pypy/annotation/annrpython.py:745>", line 3, in consider_op_simple_call [translation:ERROR] return arg.simple_call(*args) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/annotation/unaryop.py", line 175, in simple_call [translation:ERROR] return obj.call(getbookkeeper().build_args("simple_call", args_s)) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/annotation/unaryop.py", line 696, in call [translation:ERROR] return bookkeeper.pbc_call(pbc, args) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/annotation/bookkeeper.py", line 667, in pbc_call [translation:ERROR] results.append(desc.pycall(schedule, args, s_previous_result, op)) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/annotation/description.py", line 798, in pycall [translation:ERROR] return self.funcdesc.pycall(schedule, args, s_previous_result, op) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/annotation/description.py", line 283, in pycall [translation:ERROR] result = self.specialize(inputcells, op) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/annotation/description.py", line 279, in specialize [translation:ERROR] return self.specializer(self, inputcells) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/annotation/specialize.py", line 80, in default_specialize [translation:ERROR] graph = funcdesc.cachedgraph(key, builder=builder) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/annotation/description.py", line 237, in cachedgraph [translation:ERROR] graph = self.buildgraph(alt_name, builder) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/annotation/description.py", line 200, in buildgraph [translation:ERROR] graph = translator.buildflowgraph(self.pyobj) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/translator/translator.py", line 77, in buildflowgraph [translation:ERROR] graph = space.build_flow(func) [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/objspace/flow/objspace.py", line 279, in build_flow [translation:ERROR] ec.build_flow() [translation:ERROR] File "/export/home/swalker/devel/pypy/pypy/objspace/flow/flowcontext.py", line 273, in build_flow [translation:ERROR] self.space.unwrap(e.get_w_value(self.space)))) [translation:ERROR] Exception': found an operation that always raises AttributeError: generated by a constant operation: getattr [translation:ERROR] .. v119 = simple_call(v118, fd_0) [translation:ERROR] ..

strange error in urlunparse
by Max Lavrenov Oct. 10, 2011

Hello all. I make some experiments with pypy in our twisted project and get strange error in standard urlparse.urlunparse function def urlunparse(data): """Put a parsed URL back together again. This may result in a slightly different, but equivalent URL, if the URL that was parsed originally had redundant delimiters, e.g. a ? with an empty query (the draft states that these are equivalent).""" scheme, netloc, url, params, query, fragment = data if params: url =… [View More]

Feedback about the PPA packages
by Sebastien Douche Oct. 9, 2011

Oct. 9, 2011

Hi all, I'm testing the packages and I don't notice any problems with the packaging. No complain but just a remark: the good thing with cpython packaging is you can install N versions (py2.6, py2.7...) in the same machine and it doesn't to be the case with pypy packages (am I wrong?). -- Sebastien Douche <sdouche(a)gmail.com> Twitter : @sdouche

Benchmarking PyPy performance on real-world Django app
by Igor Katson Oct. 9, 2011

Oct. 9, 2011

When I first started benchmarking one of my Django sites, http://trip-travel.ru/ (using postgres driver pypq), I was disappointed by the results. PyPy was visually much slower than cPython (I just looked at how the site loads in the browser) But today I got some incredible results, I finally made PyPy to work faster than cPython, and found out that it got faster after loading the page several hundred times with "ab" or "siege" Here a the results, of mean response time by querying the home … [View More]

Hi I would like to start thinking about PyPy 1.7 and I volunteer for being a release manager. It seems modulo few failing tests we're generally in a good shape. Things I would like to get into. * my json improvements branch * justin's memory pressure branch that will hopefully fix "leak" in tornado Anyone wants to get something else there? Cheers, fijal

My favorite pypy version is 46768: It passes its own tests + It runs Django 1.3.1 :P Igor, did you try this version by any chance?

Bugs in using `easy_install` in PyPy 1.6 on Windows
by Ram Rachum Oct. 8, 2011

Oct. 8, 2011

Hey, I remember that I had trouble using `easy_install` when I was just setting up PyPy 1.6 on my XP box. I had no time to document it at that time, but I believe my workflow was to download and run distribute_setup.py, then do `easy_install pip`, and then `pip install nose`, and it didn't work so I resorted to downloading tarballs manually and running `setup.py install`, which worked. Can you add this to the test suite? I think it's something that needs to be tested automatically before any … [View More]

Why `pypy-c.exe`?
by Ram Rachum Oct. 7, 2011

Oct. 7, 2011

Why is PyPy's executable called `pypy-c.exe` on Windows? I just renamed mine to `pypy.exe`, is that okay?

Can't pickle a numpy object?
by mike c Oct. 6, 2011

Oct. 6, 2011

Hi there, I'm new to pypy and trying it out on some numerical projects and the speed of pypy+numpy is about 4x faster than cpython+numpy. Pretty impressive! However, I want to pickle some of my numpy objects and I get the error: TypeError: can't pickle numarray objects (full error is included below) I realise that the numpy implementation in pypy is currently a proof-of-concept, and so I was wondering what I would have to change to get numarray's to be pickle-able. As simple as adding a … [View More]

Oct. 6, 2011

Hi all, I am a college student interested in contributing to PyPy. I am not too sure exactly what I would like to work on, but I would ultimately like to get involved with the core JIT code, and I would prefer to work on improving the generated code rather than working on tools like the jitviewer. I would be grateful if you guys could point me to some good first bugs, and / or suggest some projects that would be in line with my interests. A little more on myself: I contributed to a fairly … [View More]
