Suggest clarification on behaviour of the __slots__ attribute when
inheriting from classes that don't have __slots__ defined. Obviously the
superclass automatically creates __dict__, and it seems the subclass
inherits this. I presume this is expected

There are two places in multiprocessing where cPickle (gone from py3k
already) is used.
Both of them are in try .. except, so they don't break code.
Here is a patch that removes these uses.

In _PyState_AddModule(), a list of (initially) 20 elements is created,
but there is no guarantee that all elements are initialized. In
particular, it appears that element 0 is always NULL. This is bad

OK,
I think I found my problem. I was using the main interpreter state

It seems that this interpreter state is reserved for GIL functions so
one will need to create a new

I mentioned this is in a brief python-dev discussion earlier this

OK I've gone back over the patch and decided to add the encoding and

originally intended, but I think it makes
New submission from Dominic Lavoie [EMAIL PROTECTED]:
This issue is similar to issue 1229429. In the called Python method, a
regular expression fails to compile PyEval_CallMethod() returns 0.
However, the reference count is incremented by 1 which prevents the
object from being destroyed.
Amaury Forgeot d'Arc [EMAIL PROTECTED] added the comment:
No, PyTuple_SET_ITEM() steals a reference to its argument, so that
ownership is transferred to the tuple.
The reference will be released when the tuple is disposed, with
Py_DECREF(arg).
What makes you think that there is a reference

Here's the good news, with the patch applied to trunk, I'm not seeing

We should disable the tests, or have someone with better Unix expertise
examine and correct them.

Adam Olsen [EMAIL PROTECTED] added the comment:
In general I suggest replacing the lock with a new lock, rather than
trying to release the existing one. Releasing *might* work in this
case, only because it's really a semaphore underneath, but it's still
easier to think about by just replacing.
Adam Olsen [EMAIL PROTECTED] added the comment:
Looking over some of the other platforms for thread_*.h, I'm sure
replacing the lock is the right thing.

OK, I have been able to reproduce the problem with a simple test

New submission from Jukka Laurila [EMAIL PROTECTED]:
Currently Python always uses the C library malloc/realloc/free as the
underlying mechanism for requesting memory from the OS, but especially
on memory-limited platforms it is often desirable to be able to override
the allocator and to redirect
Brett Cannon [EMAIL PROTECTED] added the comment:
Is registering pointers to functions really necessary, or would defining
macros work as well? From a performance perspective I would like to
avoid having a pointer indirection step every time malloc/realloc/free
is called.
I guess my question
Adam Olsen [EMAIL PROTECTED] added the comment:
How would this allow you to free all memory? The interpreter will still
reference it, so you'd have to have called Py_Finalize already, and
promise not to call Py_Initialize afterwords. This further supposes the
process will live a long time

Adrian Petrescu [EMAIL PROTECTED] added the comment:
Just as an aside, the reason I consider this a fairly serious bug is
that the Google Charts API urls make heavy use of the '|' character,
which means if I want to have Python use it by opening the user's
browser, it won't work if they don't
