It's your package. It's the community's page about your package. I think of PyPI as a community-owned noticeboard. Its primary purpose is to allow the community to find good packages -- the benefit to the community is why it exists, not the benefit to the author of the package. In my opinion, the community is best served by a good comment/review system, one which avoids the worst trolling, and allows authors the right of reply, but does not allow authors to censor inconvenient but honest reviews. -- Steven D'Aprano

External module tests skipping on Windows build slaves?
by David Bolen 14 Nov '09

14 Nov '09

While working with the Windows (and now Windows 7) build slaves I've been noticing that a number of "unexpected" test skips are occurring, mostly for external modules like ssl, bz2, tk, etc... However, I know for a fact that those libraries are being fetched and built, so I was a little perplexed that they were being skipped for testing. I don't think it's a regression due to the recent slave work, but something that may have been happening for a while, if not always. Some manual testing I did would seem to indicate that there's a problem related to loading the right MS CRT when loading these modules. But they seem to reference both debug and non-debug versions, so even if I copy the CRT DLLs (from the SxS tre) into pcbuild manually, then I get a CRT assertion about a bad initialization. I suspect this wouldn't be a problem when everything is built in release mode. I would have sworn they used to get run, but now I'm not so sure. Perhaps I'm remembering older Python releases with VS.NET 2003, since the MSVC9 versions of the CRT and the SXS stuff was new with VS 2008 I think. Does anyone happen to know if these tests have ever run recently on the Windows build slaves? -- David

No. The CPAN for Python messages (in and out of the list) are about third-party packages and a better way to manage (and a better experience of installing) those. Think Ruby, it has a significant stdlib (though not as extensive as Python's), but it also has gems (and the `gem` CLI util). Or Haskell, which also has a significant stdlib (GHC does anyway) but also has cabal and cabal-install. ------------------------------ _______________________________________________ Python-Dev mailing list Python-Dev(a)python.org http://mail.python.org/mailman/listinfo/python-dev End of Python-Dev Digest, Vol 76, Issue 114 ******************************************* Sent from my BlackBerry® powered by Sinyal Kuat INDOSAT

decimal.py: == and != comparisons involving NaNs
by Stefan Krah 13 Nov '09

13 Nov '09

Hi, in a (misguided) bugreport (http://bugs.python.org/issue7279) I was questioning the reasons for allowing NaN comparisons with == and != rather than raising InvalidOperation. I think two main issues emerge from the brief discussion: 1. Should the comparison operators follow the 'compare' function from the standard? The standard says: "An implementation may use this operation [compare] under the covers to implement a closed set of comparison operations (greater than, equal, etc.) if desired. It need not, in this case, expose the compare operation itself." So, I'd say that this supports following 'compare' as closely as possible. In fact the operators <, <=, >, >= already follow 'compare-signal' in their behavior (they raise for any NaN operand). 2. What is the use of == and != outside the decimal scope? Mark mentions that Python uses == to test for set and dict memberships, but that you cannot put decimal NaNs into sets: 'TypeError: Cannot hash a NaN value' I want to add that Decimal('NaN') == Decimal('NaN') gives False, which should somewhat limit the uses of == for NaNs outside the decimal realm anyway. Are there cases where == and != are actually needed to give a result for NaNs? Stefan Krah

Re: [Python-Dev] PyPI comments and ratings, *really*?
by Henning von Bargen 13 Nov '09

mode = "python-dev reader" Please excuse me if I'm wrong here, but I think python-dev just isn't the right place to discuss this topic, because it's about 3rd party packages and it's got nothing to do with the development *of the python language itself*, but generated a lot of traffic. mode = "package developer" I personally added a PyPI entry for my open source project just because it's there and it's a more or less standard, like CPAN in the Perl world, so I hoped others would perhaps find it there. On the other hand, if I am searching for software myself, I don't look at PyPI - I just use G**gle. I don't think PyPI needs any new features. For the "developer's social web" that support the feature, there are other good places, for example take a look at http://www.ohloh.net Henning
