[Python-Dev] Add PyDict_GetItemSetDefault() as C-API for dict.setdefault()
Hi, I've written a patch that adds a new C-API call for dict.setdefault(). The reason is that there is currently no way to test for a key and insert a fallback value for it without either evaluating the hash function twice or calling through the Python function. Both may involve considerable overhead and the double hash may have side-effects. http://bugs.python.org/issue17327 It does not include an explicit test because it does not add any code over the normal dict.setdefault() implementation, which is already tested at the Python level. If you prefer having a dummy test that checks that the function is there, I don't mind adding one. Please comment and/or apply the patch. Thanks, Stefan ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

Hi, In short, Unicode was rewritten in Python 3.3 for the PEP 393. It's not surprising that minor details like singleton differ.

I'll ask around and see what we can do. We clearly still have the download available, so it may just be a case of making the web installer publicly available again. Chances are if you have the installer then it will still work. We may also make just the compilers available in some other way. It looks like the Windows Development Kits (previously Platform SDK) don't have it, but IIRC the driver kits occasionally ship with compilers. I'll get back to the list when I get something.

The "Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 SP1" is still available for download. It includes the command line compilers that are used with VS 2008.

Someone would have to check, but in most cases, software licenses govern the use, more than the distribution. If you're allowed to download it free of charge from microsoft.com, you should be able to get hold of it in some other way and it be exactly the same. But yeah, if you want to be legal you'd have to actually read the EULA. Is there any plan for future Python versions to use a free compiler on Windows? That would eliminate this issue, but presumably would create others.

That's where I gave up. That's the point where I'd start looking at peer-to-peer downloads. These sorts of things are often available on torrent sites; once the original publisher starts making life harder, third-party sources become more attractive.

So, in the end, I have went the long way and bisected cpython to find the commit which broke my tests, and it seems that the culprit is http://hg.python.org/cpython/rev/123f2dc08b3e so it is clearly something Unicode related.

If no issue number is mentioned in the commit message, then chances are there's no specific issue in the tracker related to that particular commit. Normally there will be an issue, but sometimes things are done without one (a practice we should maybe think about changing). Most likely the commit's author, Victor Stinner, will see your message or this one and respond.

It's a distutils-sig problem because you need a way to publish any new testing related metadata, and because we're planning to evolve a hooks system to cover the different steps in the build process in a decoupled manner. "Run the tests" will be just another hook, but we're not up to dealing with that yet (the only hook that will be in metadata 2.0 is the post-install hook that will bring the wheel format up to the point of being a near-total replacement for "./setup.py install", and even that isn't written up formally yet - it's just a post in a thread on distutils-sig). You could, as Daniel suggested, work on defining a PEP 426 extension as a prototype concept, but it won't help you much until PEP 426 support is widespread, and by then we'll probably be looking at the meta-build system more broadly and figuring out the full set of desired hooks (including test invocation).
