[Python-Dev] Descriptions in unittest and avoiding confusion

For the edification of all involved, this post summarizes a somewhat surprising behavior in unittest around docstrings. In bpo-46126, I reported an issue where I’d observed that CPython developers were avoiding the use of docstrings in unittests due to what w

[Python-Dev] Windows buildbots may be broken

Jeremy informed me that due to a race condition on a test file and the CPython repo configuration for newline conversion, build bots on Windows may now be failing. If you run such a buildbot, please consider running this comma

[Python-Dev] Re: [python-committers] [RELEASE] Python 3.8.1rc1 is now available for testing

I think I missed the announcement of the cutoff date for 3.8.1; I was hoping to get some bug fixes in for importlib.metadata. These aren’t crucial bugfixes, but it would be nice not to have them linger for months. Would you consider including these,

[Python-Dev] Another case for frozendict

I repeatedly run into situations where a frozendict would be useful, and every time I do, I go searching and find the (unfortunately rejected) PEP-416. I'd just like to share another case where having a frozendict in the stdlib would be useful to me. I was interacting with a database and had a

[Python-Dev] Virtualenv not portable from Python 2.7.2 to 2.7.3 (os.urandom missing)

I see this was reported as a debian bug. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=665776 We encountered it as well. To reproduce, using virtualenv 1.7+ on Python 2.7.2 on Ubuntu, create a virtualenv. Move that virtualenv to a host with Python 2.7.3RC2 yields: jaraco@vdm-dev:~$ /

[Python-Dev] Script(s) for building Python on Windows

The current scripts for building Python lack some things to be desired. The first thing I notice when I try to build Python on Windows is the scripts expect to be run inside of a Visual Studio environment, the environment of which is only defined inside of a cmd.exe context. This means the scri

I'd like to express additional interest in python patch 1660179, discussed here: http://mail.python.org/pipermail/patches/2007-February/021687.html On several occasions, I've had the desire for something like this. I've made due with lambda functions, but as was mentioned, the lambda is cl

I'm still holding my breath for Python 2.6.2, which fixes a Windows DLL linking issue that was already fixed in 3.0.1. Obviously, the proposed schedule has passed, but I would prefer a release sooner than later. Of course, that's just my preference. Regards, Jason > -BEGIN PGP SIGNED MESS
