stuck with translation error
Hi, ran into this error, which I haven't seen before and which I can't pin down: [translation:ERROR] File "/home/wlav/pypydev/pypy/pypy/rpython/rtyper.py", line 254, in specialize_more_blocks [translation:ERROR] self.specialize_block(block) [translation:ERROR] File "/home/wlav/pypydev/pypy/pypy/rpython/rtyper.py", line 406, in specialize_block [translation:ERROR] self.translate_hl_to_ll(hop, varmapping) [translation:ERROR] File "/home/wlav/pypydev/pypy/pypy/rpython/rtyper.py", line 535, in translate_hl_to_ll [translation:ERROR] resultvar = hop.dispatch() [translation:ERROR] File "/home/wlav/pypydev/pypy/pypy/rpython/rtyper.py", line 768, in dispatch [translation:ERROR] return translate_meth(self) [translation:ERROR] File "<487-codegen /home/wlav/pypydev/pypy/pypy/rpython/rtyper.py:610>", line 4, in translate_op_simple_call [translation:ERROR] return r_arg1.rtype_simple_call(hop) [translation:ERROR] File "/home/wlav/pypydev/pypy/pypy/rpython/rpbc.py", line 723, in rtype_simple_call [translation:ERROR] return self.redispatch_call(hop, call_args=False) [translation:ERROR] File "/home/wlav/pypydev/pypy/pypy/rpython/rpbc.py", line 772, in redispatch_call [translation:ERROR] assert hop.nb_args == 1, ("arguments passed to __init__, " [translation:ERROR] AssertionError: arguments passed to __init__, but no __init__!

False)), v0, ('raw'), (False)), v2 = simple_call((type error), ('out of resources'))] which I presume is lltype.free() of which I have a few calls, but no recent changes (and I don't understand the complaint about __init__ at that point). I'm going to roll back history to see where things broke, but if the above rings a bell with someone, that could spare me some time ... Thanks!

Hm, it can also be the next operation: v2 = simple_call((type error), ('out of resources')) What is this "error" object? Some local exception class? -- Amaury Forgeot d'Arc
Hi Amaury,
[v1 = call_args((function free), ((1, ('flavor', 'track_... False)), v0, ('raw'), (False)), v2 = simple_call((type error), ('out of resources'))]
Hm, it can also be the next operation: v2 = simple_call((type error), ('out of resources'))
I was under the impression that that was a standard error, but then again that would have been for malloc(), not free(). I searched again and came up with is code in ll_thread.py: def allocate_ll_lock(): # track_allocation=False here; be careful to lltype.free() it. The # reason it is set to False is that we get it from all app-level # lock objects, as well as from the GIL, which exists at shutdown. ll_lock = lltype.malloc(TLOCKP.TO, flavor='raw', track_allocation=False) res = c_thread_lock_init(ll_lock) if rffi.cast(lltype.Signed, res) <= 0: lltype.free(ll_lock, flavor='raw', track_allocation=False) raise error("out of resources") return ll_lock which looks very much like it (the link to the exit is a raise). So I think that it isn't my code that doesn't translate. :) Beats me then, why it would bite me.
What is this "error" object? Some local exception class?
I can look again in a half an hour: I had just restarted the translation after a removing some of my recent changes. But I'll bet it's what I see here above in allocate_ll_lock. The module ll_thread.py defines: class error(Exception): pass Thanks, Wim -- WLavrijsen@lbl.gov -- +1 (510) 486 6411 -- www.lavrijsen.net
Hi,
[translation:ERROR] File "<487-codegen /home/wlav/pypydev/pypy/pypy/rpython/rtyper.py:610>", line 4, in translate_op_simple_call [translation:ERROR] return r_arg1.rtype_simple_call(hop) [translation:ERROR] File "/home/wlav/pypydev/pypy/pypy/rpython/rpbc.py", line 723, in rtype_simple_call [translation:ERROR] return self.redispatch_call(hop, call_args=False) [translation:ERROR] File "/home/wlav/pypydev/pypy/pypy/rpython/rpbc.py", line 772, in redispatch_call [translation:ERROR] assert hop.nb_args == 1, ("arguments passed to __init__, " [translation:ERROR] AssertionError: arguments passed to __init__, but no __init__!
got it, and funnily enough it even had something to do with an __init__ (but that wasn't the actual cause). I had some code to raise an exception in init if an attempt was made to instantiate an abstract C++ class. In that code, I did: except Exception, e: if e.match(self.space, self.space.w_AttributeError): whereas it should have been: except OperationError, e: if e.match(self.space, self.space.w_AttributeError): the point being that the code changes an AttributeError (failure to find a suitable method, i.e. a usable C++ constructor) into a TypeError (stating that the class is abstract). I'm actually surprised that the bad code made it past the rtyper, given that class Exception does not actually have a match() method. Either way, I don't think I deserved such a horrible error message for such a little coding mistake. :} But there's a good deal of irony here in that the code that caused the horrible error message on me is there to make an error in user code more clear.
