How about updating OrderedDict in csv and configparser to regular dict?
by INADA Naoki 31 Jan '19

31 Jan '19

Hi, csv.DictReader uses OrderedDict by default, from Python 3.6. But it doesn't make sense anymore, like namedtuple._asdict(). How about changing default dict type back to regular dict. Python is widely used for handling learge data. So I think changing default dict type to OrderedDict was performance and memory usage regression in 3.6. Additionally, configparser uses OrderedDict by default from Python 3.6 too. I am not sure about `parser['section1'] == parser['section2']` is not used yet. But we broke it once in 3.6 by changing dict to OrderedDict. Are there any issue report caused by this backward incompatibility? And I think performance and memory efficiency is not so important for configparser, unlike csv. I'm * +1 about changing csv.DictReader's default dict type * +0.5 about changing configparser's default dict type. How do you think? Regards, -- INADA Naoki <songofacandy(a)gmail.com>

Summer of Code 2019 Mentors
by Matthew Lagoe 30 Jan '19

30 Jan '19

Hi Python community folk! As we've done for the past many years, Python is hoping to participate in Google Summer of Code. This is a neat program where students write code over the (northern hemisphere) summer under the tutelage of open source mentors and get paid: we provide the project ideas, mentors and choose the students, Google provides the program framework and the money to pay students. You can read more about GSoC here: https://summerofcode.withgoogle.com/ Python participates as an "umbrella org" where many different smaller projects ("sub orgs") that use Python can take part under our banner. You can also participate separately, but for people who've never done it before and want help or for whom the paperwork is a hassle, you're welcome to join up with us and let us show you the ropes! It's really fun, and we've gotten lots of new contributors to Python-based projects over the years, taking in as many as 70+ students in a single year. Last year we only had 15, though, so we've got lots of space for new mentors and new projects. We didn't have any projects for core python last year as there were no mentors for the projects, so if anyone is interested in mentoring this year let us know asap! You can also send questions to gsoc-admins(a)python.org (or just hit reply to this email!)

[ANN] "compiler" package resurrected
by Paul Sokolovsky 30 Jan '19

30 Jan '19

Hello, I'm sorry for posting here and not to python-announce, somehow I think (perhaps naively) that it may be of interest to people who are interested in Python development. At the very least, creation of the original package is (very likely, I didn't trace up to that) was discussed on python-dev, its removal was discussed on python-dev, so why revival of it can't be noted here? Because, turns out, in old good times, there was a bytecode compiler written in Python, and even as a part of stdlib. Well, actually it's still there in the latest 2.7 release, with a proud notice: "Remove in Python3". The point is that I'm with Python since 1.5 times, and never knew about this package. I'd generally consider that to be something to be ashamed and hush of, but unfortunately I found that to be recurring pattern: people interested in playing with a Python compiler discover "by a chance" and "suddenly" that they should look no beyond the stdlib for their (usually pretty simple for starters) needs - oftentimes, after they already started on the more effortful path (I faithfully spent 2 days on trying to extract a bytecode compiler from PyPy first). With that intro, here's it - the port of Python2 compiler package (https://docs.python.org/2/library/compiler.html) to Python3: https://github.com/pfalcon/python-compiler Currently, it generates bytecode compatible with CPython3.5, and is able to compile its entire Lib/ (which includes not just stdlib modules per se, but also tests, and the real "teeth-cracking" stuff is there of course), except for test_super.py, for which current implementation's teeth are indeed too weak yet. Now that it passes the compile-stdlib test, the idea is to refactor it into something which can be easily played with and extended. We'll see how it goes. As one of the example of what's intended to be easily done with it, see thread https://mail.python.org/pipermail/python-dev/2019-January/155991.html . I started it when updating the codegen for Python3, but also shows the intended purpose - it would easy to analyze if an except handler body contains "del exc" and if not, skip generating superfluous bytecode. -- Best regards, Paul mailto:pmiscml@gmail.com

Sub-interpreters: importing numpy causes hang
by Stephan Reiter 28 Jan '19

28 Jan '19

Hi all! I am new to the list and arriving with a concrete problem that I'd like to fix myself. I am embedding Python (3.6) into my C++ application and I would like to run Python scripts isolated from each other using sub-interpreters. I am not using threads; everything is supposed to run in the application's main thread. I noticed that if I create an interpreter, switch to it and execute code that imports numpy (1.13), my application will hang. ntdll.dll!NtWaitForSingleObject() Unknown KernelBase.dll!WaitForSingleObjectEx() Unknown > python36.dll!_PyCOND_WAIT_MS(_PyCOND_T * cv=0x00000000748a67a0, _RTL_CRITICAL_SECTION * cs=0x00000000748a6778, unsigned long ms=5) Line 245 C [Inline Frame] python36.dll!PyCOND_TIMEDWAIT(_PyCOND_T *) Line 275 C python36.dll!take_gil(_ts * tstate=0x0000023251cbc260) Line 224 C python36.dll!PyEval_RestoreThread(_ts * tstate=0x0000023251cbc260) Line 370 C python36.dll!PyGILState_Ensure() Line 855 C umath.cp36-win_amd64.pyd!00007ff8c6306ab2() Unknown umath.cp36-win_amd64.pyd!00007ff8c630723c() Unknown umath.cp36-win_amd64.pyd!00007ff8c6303a1d() Unknown umath.cp36-win_amd64.pyd!00007ff8c63077c0() Unknown umath.cp36-win_amd64.pyd!00007ff8c62ff926() Unknown [Inline Frame] python36.dll!_PyObject_FastCallDict(_object *) Line 2316 C [Inline Frame] python36.dll!_PyObject_FastCallKeywords(_object *) Line 2480 C python36.dll!call_function(_object * * * pp_stack=0x00000048be5f5e40, __int64 oparg, _object * kwnames) Line 4822 C Numpy's extension umath calls PyGILState_Ensure(), which in turn calls PyEval_RestoreThread on the (auto) threadstate of the main interpreter. And that's wrong. We are already holding the GIL with the threadstate of our current sub-interpreter, so there's no need to switch. I know that the GIL API is not fully compatible with sub-interpreters, as issues #10915 and #15751 illustrate. But since I need to support calls to PyGILState_Ensure - numpy is the best example -, I am trying to improve the situation here: https://github.com/stephanreiter/cpython/commit/d9d3451b038af2820f500843b6a… That change may be naive, but it does the trick for my use case. If totally wrong, I don't mind pursuing another alley. Essentially, I'd like to ask for some guidance in how to tackle this problem while keeping the current GIL API unchanged (to avoid breaking modules). I am also wondering how I can test any changes I am proposing. Is there a test suite for interpreters, for example? Thank you very much, Stephan

Anyone else seeing a lack of caching in local docs builds?
by Nick Coghlan 28 Jan '19

28 Jan '19

Hi folks, I'm currently seeing a behaviour where every time I run "make html", all 474 source files get rebuilt. For now, I'm assuming I've messed something up with my local docs build setup, but figured I'd ask if anyone else was seeing this, in case it was actually broken at the build level (CI wouldn't pick this up, since it always builds from scratch anyway). Cheers, Nick. -- Nick Coghlan | ncoghlan(a)gmail.com | Brisbane, Australia

Source of truth for C-API
by Ivan Levkivskyi 27 Jan '19

27 Jan '19

Hi, I recently modified signatures of two functions PyNode_AddChild() and PyParser_AddToken(). These two functions are not listed in C-API docs on docs.python.org, and are not included in Python.h. However, their names look like they may be part of C-API. So there appeared a question, what is the source of truth for C-API, is there an official list? Or is it just the content of Python.h? -- Ivan

Lost sight
by Serhiy Storchaka 24 Jan '19

24 Jan '19

I have virtually completely lost the sight of my right eye (and the loss is quickly progresses) and the sight of my left eye is weak. That is why my activity as a core developer was decreased significantly at recent time. My apologies to those who are waiting for my review. I will do it slowly.

ctypes: is it intentional that id() is the only way to get the address of an object?
by Steven D'Aprano 19 Jan '19

19 Jan '19

Disclaimer: I'm not a ctypes expert, so I might have this completely wrong. If so, I apologise for the noise. The id() function is documented as returning an abstract ID number. In CPython, that happens to have been implemented as the address of the object. I understand that the only way to pass the address of an object to ctypes is to use that id. Is that intentional? As I see it, there is a conflict between two facts: - that id() returns a memory address is an implementation detail; as such users should not rely on it, as the implementation could (in principle) change without notice; - but users using ctypes have no choice but to rely on id() returning the object memory address, as of it were an offical part of the API. Implementations like PyPy which emulate ctypes, while objects don't have fixed memory locations, will surely have a problem here. I don't know how PyPy solves this. Have I misunderstood something here? -- Steve
