[issue5738] multiprocessing example wrong

[Ask Solem]

Ask Solem  added the comment:

Are we sure this fits the scope of multiprocessing? It's a nice feature, 
but such a long and complex example in the documentation is wrong IMHO, if 
this is something people need it should be implemented as a reusable 
solution, not as an example people copy and paste.

In hindsight; I agree - this belongs in an "addons" module someplace
outside the standard library. I'll remove it today - the one thing we
are short on though is manager examples.

[issue7272] test_multiprocessing fails consistently with 'signal 12' on FreeBSD 6.2 buildbot.

Well, there should be a skip message next to the test_multiprocessing line 
in the results.  I'm not sure whether that's the sort of thing you mean.

Unfortunately it looks like both runs (6.4 and 7.2) were prematurely 
terminated by test_curses before they even got as far as 
test_multiprocessing.  I might try running them again and hope for a 
different random test ordering.

I'm also seeing warnings about HAVE_BROKEN_POSIX_SEMAPHORES being 
redefined, in Python/thread_pthread.h;  I'll take another look at this 
next week (no access to the FreeBSD machine at the moment).

That would be great---thank you!

I'm not sure we are, just yet.  But soon... :)

[issue7353] cporting docs recommend using Include/intobject.h, which was removed in 3.1?

[Guido van Rossum]

Guido van Rossum  added the comment:

I don't think it would hurt to put it back, would it?  I think the "remove 
this in 3.1" note was made when we expected 3.1 to be happening 1.5 years 
after 3.0 rather than a few months.

Yes. But, I would remove the ugly copy_reg_str variable from cPickle as

[issue7373] Use PyModule_AddIntMacro() in Modules/gcmodule.c

[Jon Parise]

New submission from Jon Parise :

The attached patch uses PyModule_AddIntMacro() to register the gc
module's constants instead of using a local ADD_INT() macro.

[issue7373] Use PyModule_AddIntMacro() in Modules/gcmodule.c

[Jon Parise]

Jon Parise  added the comment:

That's true.  I thought it worked the same as the ADD_INT() macro I
replaced, but I see that I was wrong.

Given that, perhaps the original code is best.  I don't see a lot of
value in replacing PyModule_AddIntConstant() with PyModule_AddIntMacro()
within ADD_INT().

[issue7173] Cython compiler run crashes CPython 3.1.1 and 3.2

[Stefan Behnel]

Stefan Behnel  added the comment:

I hadn't, but it looks like the 2to3-ed Cython also runs on 3.0 now, so
I tested that, but I failed to get the procedure below to crash for me.
And that's both in 3.0 *and* 3.1.1! :-/

But I can still provoke the crash in 3.0, 3.0.1, 3.1.1 and the latest
3.2 when running the test suite normally, so it's still there, and it's
been there for a while.

At least a debug build of the latest py3k SVN rev. 76441 (3.2a0) seems
to crash reliably for the latest Cython (cython-devel, rev.
76a814a1fc57) with the attached crash patch applied. Running the
following crashes after printing the "HERE1":

python3.2 runtests.py --no-cpp --no-pyregr --no-doctest \
 --no-cpp --no-fork --no-refnanny -vv first_assignment

with the error:
"""
python3.2: Objects/unicodeobject.c:885: PyUnicodeUCS4_FromFormatV:
Assertion `obj' failed.
Aborted
"""
which occurs when it's trying to print() the dead exception. Again, no
Cython modules have been loaded up to this point, so this is still pure
Python code that crashes the interpreter.
