Adding a threadlocal to the Python interpreter
by Daniel Holth 27 May '16

27 May '16

I would like to take another stab at adding a threadlocal "str(bytes) raises an exception" to the Python interpreter, but I had a very hard time understanding both how to add a threadlocal value to either the interpreter state or the threadlocal dict that is part of that state, and then how to access the same value from both Python and CPython code. The structs were there but it was just hard to understand. Can someone explain it to me? Thanks, Daniel Holth

devinabox has moved to GitHub
by Brett Cannon 26 May '16

26 May '16

https://github.com/python/devinabox The single issue for devinabox has moved to its own issue tracker, so there's no need to worry about those issues cluttering b.p.o in the future. I have made the Python core team I created on GitHub last week have write privileges and Nick and I as admins on the repository. I have also turned on the CLA bot for the repository (FYI https://github.com/python/the-knights-who-say-ni has that bot's code). I've asked Georg, Antoine, and Benjamin to tell me what I need to do to shut off -- either by making it read-only or just deleting -- hg.python.org/devinabox. Now that the migration has seriously begun, the next repos will be the peps and devguide (slightly more complicated thanks to needing to update commands for building their online versions). There's also the benchmarks repo, but that might not get migrated if we start from scratch (see the speed@ ML about that). As for cpython, I've been asked to talk about it at the language summit where I will start a conversation about what the minimal feature set will need to be to migrate. Once we have settled on what has to be in place to migrate the cpython repo then we can start working on that TODO list.

Removing the provisional label from pathlib
by Brett Cannon 24 May '16

24 May '16

Three questions: 1. Should pathlib gain __fspath__() all the way back to 3.4? 2. Should pathlib's constructor support __fspath__() all the way back to 3.4? (separate question as os.fspath() will only be in 3.6; and if we backport I'm not looking forward to making Typeshed happy w/o os.PathLike being available only in 3.6 :/) 3. Should the docs from 3.4 and forward reflect the removal of the provisional status? (I assume yes, but wanted to double-check) And a quick thanks to Guido for removing `path` from pathlib for me already. :)

Re: [Python-Dev] [Python-checkins] cpython: Issue #26647: Python interpreter now uses 16-bit wordcode instead of bytecode.
by Brett Cannon 24 May '16

24 May '16

This probably deserves a "What's New" entry since it does break bytecode-inspecting code.

Python 3.6.0a1 is now available
by Ned Deily 24 May '16

24 May '16

On behalf of the Python development community and the Python 3.6 release team, I'm happy to announce the availability of Python 3.6.0a1. 3.6.0a1 is the first of four planned alpha releases of Python 3.6, the next major release of Python. During the alpha phase, Python 3.6 remains under heavy development: additional features will be added and existing features may be modified or deleted. Please keep in mind that this is a preview release and its use is not recommended for production environments. You can find Python 3.6.0a1 here: https://www.python.org/downloads/release/python-360a1/ The next release of Python 3.6 will be 3.6.0a2, currently scheduled for 2016-06-13. Enjoy! --Ned -- Ned Deily nad(a)python.org -- []

Why does PEP 7/8 explicitly suggest 2 spaces after a period?
by Brett Cannon 22 May '16

22 May '16

Is there a specific reason for calling out two spaces in comments after a period(I realize it's probably for consistency, but I sure don't ever think about this when I write comment)? Otherwise who actually still writes using two spaces after punctuation? :)

Adding Type[C] to PEP 484
by Guido van Rossum 21 May '16

21 May '16

I've got another proposed update to PEP 484 ready. There was previously some discussion on python-ideas (Bcc'ed for closure) and quite a bit on the typing issue tracker: https://github.com/python/typing/issues/107 I've worked all that into a patch for PEP 484: https://github.com/python/typing/pull/218 Once we're okay with that I will work on getting the implementation ready in time for Python 3.5.2. Here's the added text: Meta-types ---------- A meta-type can be used to indicate a value that is itself a class object that is a subclass of a given class. It is spelled as ``Type[C]`` where ``C`` is a class. To clarify: while ``C`` (when used as an annotation) refers to instances of class ``C``, ``Type[C]`` refers to *subclasses* of ``C``. (This is a similar distinction as between ``object`` and ``type``.) For example, suppose we have the following classes:: class User: ... # Abstract base for User classes class BasicUser(User): ... class ProUser(User): ... class TeamUser(User): ... And suppose we have a function that creates an instance of one of these classes if you pass it a class object:: def new_user(user_class): user = user_class() # (Here we could write the user object to a database) return user Without ``Type[]`` the best we could do to annotate ``new_user()`` would be:: def new_user(user_class: type) -> User: ... However using ``Type[]`` and a type variable with an upper bound we can do much better:: U = TypeVar('U', bound=User) def new_user(user_class: Type[U]) -> U: ... Now when we call ``new_user()`` with a specific subclass of ``User`` a type checker will infer the correct type of the result:: joe = new_user(BasicUser) # Inferred type is BasicUser At runtime the value corresponding to ``Type[C]`` must be an actual class object that's a subtype of ``C``, not a special form. IOW, in the above example calling e.g. ``new_user(Union[BasicUser, ProUser])`` is not allowed. There are some concerns with this feature: for example when ``new_user()`` calls ``user_class()`` this implies that all subclasses of ``User`` must support this in their constructor signature. However this is not unique to ``Type[]``: class methods have similar concerns. A type checker ought to flag violations of such assumptions, but by default constructor calls that match the constructor signature in the indicated base class (``User`` in the example above) should be allowed. A program containing a complex or extensible class hierarchy might also handle this by using a factory class method. Plain ``Type`` without brackets is equivalent to using ``type`` (the root of Python's metaclass hierarchy). This equivalence also motivates the name, ``Type``, as opposed to alternatives like ``Class`` or ``SubType``, which were proposed while this feature was under discussion; this is similar to the relationship between e.g. ``List`` and ``list``. -- --Guido van Rossum (python.org/~guido)

PyGC_Collect ignores state of `enabled`
by Łukasz Langa 20 May '16

20 May '16

Is this deliberate? Could we change it for 3.6 so PyGC_Collect does take `enabled` into account? Context: we’re experimenting with disabling the gc entirely for some workloads because it doesn’t fare too well with Copy-on-Write on Linux. What ends up happening is that disabling the gc actually drops memory usage significantly if you’re using hundreds of the same processes on one box :-) However, because of PyGC_Collect() called in Py_Finalize(), during interpreter shutdown the collection is done anyway, Linux does CoW and the memory usage spikes. Which is ironic on process shutdown. -- Lukasz Langa | Facebook Production Engineer | The Ministry of Silly Walks (+1) 650-681-7811
