That's for new contributors, not for old, lapsed contributors. wink Also, it still seems to me that the ASDLGEN definition should reference something that is explicitly Python 3 and can't accidentally execute a Python 2.x interpreter (or, the AST-generation script should work in both Python 2.x and 3.x).

[issue21485] remove unnecesary .flush() calls in the asyncio subprocess code example
New submission from akira: The current code example contains [1]: print(Python failed with exit code %s: % exitcode) sys.stdout.flush() sys.stdout.buffer.flush() sys.stdout.buffer.write(stdout) sys.stdout.buffer.flush() that looks bizarre. Either a comment should be added that explains why the `.flush()` calls are necessary or they should be removed. I've attached the documentation patch that removes the calls.

Tim Peters added the comment: [haypo] What is an uninteresting sequence? What are the problem of these sequences? A sequence that would greatly surprise a user. For example, if you generate 32-bit ints from the Twister in one obvious way, there are starting places where you'll get 623 zeroes in a row. And places where you'll get 2**32-1 623 times in a row. Pick a sequence of any 623 32-bit ints, and there's a starting place that will deliver that sequence. And, indeed, a truly random sequence must also display that behavior, but it's nevertheless very surprising when you see one. It's very rare, both in a truly random sequence and in sequences derived from the Twister. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21470 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue21470] Better seeding for the random module
Tim Peters added the comment: [haypo] No user complained past years. Raymond said We've previously had this problem with MT (since resolved, where it is was landed in a very non-random zone). Do you believe he was wrong? I don't think that we should worry so much, because it looks like reading more data from /dev/urandom can be a more serious and concrete issue. Why do you say that? Most links people have found and posted here clearly say that the Linux warnings about urandom are basically nonsense. Please supply references to back up serious and concrete (or point to earlier references, if you found them convincing). I'm with Raymond on this. There is no useful theory that allows us to predict the characteristics of the produced sequences from a set of possible seeds, so limiting the set of possible seeds is potentially dangerous. The theory about equidistribution (etc) is very useful, but relies on mathematical analysis of the _entire_ period of the generator. The only way to span the entire period is to allow for all possible seeds. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21470 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue21470] Better seeding for the random module
Antoine Pitrou added the comment: There is no useful theory that allows us to predict the characteristics of the produced sequences from a set of possible seeds, so limiting the set of possible seeds is potentially dangerous. I still find it difficult to understand where is the said danger. As you point out, a sequence of zeroes is a valid random sequence, and there is no reason to believe that a sequence of zeroes is more likely with a 256 bits seed, than with a 20 kbits seed (it might as well be less likely, for all we know). We may as well bump it from 256 to 512 or 1024 bits, but 20 kbits sounds extremely unusual for a program to read from /dev/urandom at startup. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21470 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue21418] Segv during call to super_init in application embedding Python interpreter.
STINNER Victor added the comment: While embedding the Python interpreter in an application, I have encountered a crash when the built-in function 'super' is invoked with no arguments. This is not supported. When super() is invoked with no arguments, the class is retrieved (indirectly) from the current frame. In your example, there is no current frame. You can workaround this limitation by passing explicitly the class to super. The crash should be fixed: a RuntimeError is now raised. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21418 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue21470] Better seeding for the random module
Tim Peters added the comment: [pitrou] I still find it difficult to understand where is the said danger. The theoretical properties that make the Twister so attractive were all proved based on mathematical analysis of its entire period. The only way to get at the whole period is to allow for all possible seeds. If the seeds Python can use are drawn from a relatively tiny subset of the possible seeds, nothing can be said about most of the proved correct properties anymore. Maybe they still hold. Maybe they don't. In the absence of analysis (which, AFAIK, is still too difficult to do), the only way to be safe is to refrain from being so bloody clever in the interest of saving a few microseconds. As you point out, a sequence of zeroes is a valid random sequence, and there is no reason to believe that a sequence of zeroes is more likely with a 256 bits seed, than with a 20 kbits seed (it might as well be less likely, for all we know). That's the point: we don't _know_ much of anything if we restrict to a subset of possible seeds. But we DO know if all possible seeds are allowed for. Then the Twister has many nice properties, and provably so. Allowing for all possible seeds is judicious: it's an acknowledgement of our ignorance, and a statement that we're more concerned with correctness than micro-efficiency in a (typically) zero- or one-time-per-process `random` initialization cost. We may as well bump it from 256 to 512 or 1024 bits, That's as unprincipled as using 1 bit - although _likely_ to give better results ;-) but 20 kbits sounds extremely unusual for a program to read from /dev/urandom at startup. At least on my box, starting Python does not import `random`, and the seeding code isn't called at all. It's only called when `random` is imported. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21470 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue21489] Switching from -OO to -O still uses cached bytecode
New submission from Matthew Fernandez: Perhaps others wouldn't consider this a bug, but it was definitely surprising to me. When switching between optimisation levels -OO (optimise and strip docstrings) and -O (just optimise), you will find the docstrings are still stripped.

[issue21412] core dump in PyThreadState_Get when built --with-pymalloc
STINNER Victor added the comment: Victor: sure; see attached. Ok, so the error occurs when Python tries to import the _heapq dynamic module: PyModule_Create2() calls PyThreadState_Get() to retrieve to current thread, but it fails. There is a current thread because PyModule_Create2() is called indirectly by PyEval_EvalFrameExReal() (and I don't see where the GIL would be released in the call stack). It looks like a bug in PyThreadState_Get(). This function relies on _Py_atomic_load_relaxed() which is defined in Include/pyatomic.h. This file has an implementation of atomic functions for Intel processors and contains an interesting comment: ... #else /* !gcc x86 */ /* Fall back to other compilers and processors by assuming that simple volatile accesses are atomic. This is false, so people should port this. */ ... It looks like John tries Python on SPARC which may explain the issue. This is just a theory. It also looks like we had SPARC buildbots running on Solaris with system C compiler (/opt/solarisstudio12.3/bin/cc) and it was able to run tests. I don't understand the link with pymalloc. @John: Did you try to build Python 3.3?
