That doesn't > seem too onerous to me. You can start with zero, but unless the Enum is mixed with a numeric type it will evaluate to True. Also, but there are other falsey values that a pure Enum member could have: False, None, '', etc., to name a few. However, as Barry said, writing your own is a whopping two lines of code: def __bool__(self): return bool(self._value_) With Barry and Guido's feedback this issue is closed.

Building with VS2015

I downloaded https://www.python.org/ftp/python/3.4.4/Python-3.4.4.tgz. After reading Python-3.4.4\PCbuild\readme.txt I opened pcbuild.sln and selected release/winn32 then tried a build all (F7). But that give lots of errors and missing .h files (mostly sqlite3.h). Does anyone know what I may be doing wrong or have misunderstood? Here is the output: 1>------ Build started: Project: make_versioninfo, Configuration: Release Win32 ------ 2>------ Build started: Project: kill_python, Configuration: Release Win32 ------ 3>------ Skipped Build: Project: bdist_wininst, Configuration: Release Win32 ------ 3>Project not selected to build for this solution configuration 4>------ Build started: Project: python3dll, Configuration: Release Win32 ------ 5>------ Build started: Project: xxlimited, Configuration: Release Win32 ------ 1> make_versioninfo.c 5> xxlimited.c 2> kill_python.c 4> 4> Microsoft (R) Program Maintenance Utility Version 14.00.23026.0 4> Copyright (C) Microsoft Corporation.

2.7.11 Windows Installer issues on Win2008R2
by Rader, David Jan. 15, 2016

Jan. 15, 2016

Problem 1: The .manifest information for the VC runtime dll's has been changed in the recent versions of the 2.7.x 64-bit installers for Windows. Python fails to run on a clean Win2008R2 install after running the Python installer to install "Just for me". The installation succeeds if "Install for all users" is selected. After install completes, trying to run python results in: The application has failed to start because it's side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail. The event viewer log shows: Activation context generation failed for "C:\Python27\python.exe".Error in manifest or policy file "C:\Python27\Microsoft.VC90.CRT.MANIFEST" on line 4. Component identity found in manifest does not match the identity of the component requested. Reference is Microsoft.VC90.CRT,processorArchitecture="amd64",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="9.0.21022.8". Definition is Microsoft.VC90.CRT,processorArchitecture="amd64",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="9.0.30729.1". Please use sxstrace.exe for detailed diagnosis. This means that that VC2008 SP1 dll and manifest are included in the installer, but the Python.exe is compiled against VC2008 (_not_ SP1). Replacing the installed manifest and VC90 with one pulled from an older distribution with the correct 9.0.21022.8 version enables python to run. Problem 2: The compiled DLLs in the DLLs folder incorrectly have the VC manifest included in them as well. This breaks the side-by-side look up, since the VC90 dll is not in the DLLs folder. So if you try to import socket, you get an error message like: Traceback (most recent call last): File "hub\scripts\pgc.py", line 9, in <module> import socket File "C:\Python27\lib\socket.py", line 47, in <module> import _socket ImportError: DLL load failed: The application has failed to start because its si de-by-side configuration is incorrect. Please see the application event log or u se the command-line sxstrace.exe tool for more detail. Previous versions of Python for windows have had this problem but it was corrected. It looks like it has crept back in. -- David Rader

Boolean value of an Enum member
by Ethan Furman Jan. 15, 2016

Jan. 15, 2016

When Enum was being designed one of the questions considered was where to start autonumbering: zero or one. As I remember the discussion we chose not to start with zero because we didn't want an enum member to be False by default, and having a member with value 0 be True was discordant. So the functional API starts with 1 unless overridden. In fact, according to the Enum docs: The reason for defaulting to ``1`` as the starting number and not ``0`` is that ``0`` is ``False`` in a boolean sense, but enum members all evaluate to ``True``. However, if the Enum is combined with some other type (str, int, float, etc), then most behaviour is determined by that type -- including boolean evaluation. So the empty string, 0 values, etc, will cause that Enum member to evaluate as False. So the question now is: for a standard Enum (meaning no other type besides Enum is involved) should __bool__ look to the value of the Enum member to determine True/False, or should we always be True by default and make the Enum creator add their own __bool__ if they want something different? On the one hand we have backwards compatibility, which will take a version to change. On the other hand we have a pretty basic difference in how zero/empty is handled between "pure" Enums and "mixed" Enums. On the gripping hand we have . . . Please respond with your thoughts on changing pure Enums to match mixed Enums or any experience you have had with relying on the "always True" behaviour or if you have implemented your own __bool__ to match the standard True/False meanings or if you have implemented your own __bool__ to match some other scheme entirely. -- ~Ethan~

Discussion related to memory leaks requested
by Matthew Paulson Jan. 14, 2016

Jan. 14, 2016

Hi: I've spent some time performing memory leak analysis while using Python in an embedded configuration. The pattern is: Py_Initialize(); ... run empty python source file ... Py_Finalize(); I've identified several suspect areas including dictionary maitenace in import.c:~ 414 /* Clear the modules dict. */ PyDict_Clear(modules); /* Restore the original builtins dict, to ensure that any user data gets cleared. */ dict = PyDict_Copy(interp->builtins); if (dict == NULL) PyErr_Clear(); PyDict_Clear(interp->builtins); if (PyDict_Update(interp->builtins, interp->builtins_copy)) PyErr_Clear(); Py_XDECREF(dict); /* Clear module dict copies stored in the interpreter state */ Is there someone in the group that would like to discuss this topic. There seems to be other leaks as well. I'm new to Python-dev, but willing to help or work with someone who is more familiar with these areas than I. Thanks, Matt --

PEP 509
by Jim J. Jewett Jan. 14, 2016

Jan. 14, 2016

(1) Please make it clear within the abstract what counts as a change. (1a) E.g., a second paragraph such as "Adding or removing a key, or replacing a value, counts as a change. Modifying an object in place, or replacing it with itself may not be picked up." (1b) Is there a way to force a version update? d[k]=d[k] seems like it should do that (absent the optimization to prevent it), but I confess that I can't come up with a good use case that doesn't start seeming internal to a specific optimizer. (1c) Section "Guard against changing dict during iteration" says "Sadly, the dictionary version proposed in this PEP doesn't help to detect dictionary mutation." Why not? Wouldn't that mutation involve replacing a value, which ought to trigger a version change? (2) I would like to see a .get on the guard object, so that it could be used in place of the dict lookup even from python. If this doesn't make sense (e.g., doesn't really save time since the guard has to be used from python), please mention that in the Guard Example text. (3) It would be possible to define the field as reserved in the main header, and require another header to use it even from C. (3a) This level of privacy might be overkill, but I would prefer that the decision be explicit. (3b) The change should almost certainly be hidden from the ABI / Py_LIMITED_API -jJ

Modifying the self-signed.pythontest.net certificate
by Martin Panter Jan. 13, 2016

Jan. 13, 2016

In order to fix the SSL test suite <https://bugs.python.org/issue25940>, I would like to modify the certificate used by https://self-signed.pythontest.net. So far I have a patch ready for the pythontestdotnet repository, but I want to know if I can just push to that repository, or if other steps are required. Judging by <https://bugs.python.org/issue22650>, Georg Brandl was involved in setting the server up. So far I haven’t heard anything from him on the SSL tests bug, so I am asking here in case somebody else can help.

GitHub migration planning has started
by Brett Cannon Jan. 10, 2016

Jan. 10, 2016

For those of you who have not heard, I made the decision a little over a week ago to move Python's development from our home-grown workflow to one hosted on GitHub (mainly for code hosting and code review; we're keeping bugs.python.org for our issue tracker). The hope is that this will let core developers work through patches faster so that we have a better turn-around time while being at least as good as our current workflow for external contributors (but I will be shocked if it isn't better). There are also people involved with the migration who plan to put in the effort to make sure external contributors can still submit patches without ever interacting with GitHub. If you want to help with the transition, then feel free to join the core-workflow mailing list where all the discussions on the details of the migration are occurring (including the PEP I'm starting to write to outline the steps we will be taking): https://mail.python.org/mailman/listinfo/core-workflow
