I'm working on improving the .rst documentation of test.support (Issue 11015), and came upon the undocumented "fcmp" function that's being exported from test.support, along with a "FUZZ"constant. As I search through the tests (py3k trunk), I see fcmp() is being used only in two places in a fairly trivial way: 1. test_float: where it can be directly replaced by assertAlmostEqual from unittest 2. test_builtin: where the assertion can also be easily rewritten in terms of assertAlmostEqual Although fcmp seems to provide extra functionality over assertAlmostEqual, the above makes me think it should probably be removed altogether, or added to unittest if it's still deemed important. +/- ?

Beta version of the new devguide

by Brett Cannon

http://docs.python.org/devguide/ If you are a core developer and have a correction you want to make you can simply check out the devguide yourself (link is in the Resources section of the devguide) and make the corrections yourself. Otherwise reply here (you can email me directly but I already have instances of multiple people telling me about the same spelling mistake so it's nice to have it public so people know when I have been informed). As for what is left to do, there are a a few things. One is fixing some issues to allow test coverage to be run for the entire test suite (see the coverage docs to know what issues are tracking the problems). I will work on this next if no one beats me to it as both issues should be relatively simple to do. Two, what should the final URL be? Georg picked the current one and I am happy with it. Three, where should it be linked from? docs.python.org homepage? Four, what to do with www.python.org/dev/? Redirect for all the pages? Otherwise I consider the devguide ready to go. My next thing will be an "official" HOWTO on dealing with Python 2/3 porting/maintenance.

getting stable URLs for major.minor versions

by Brett Cannon

Because of all the writing I have been doing lately, I have been pulling up a lot of URLs pointing to various Python releases based around minor versions (e.g., Python 2.7, not specifically 2.7.1). What has been somewhat annoying is that there are no URLs which act as a redirect to the latest release of a minor version. For instance, it would be great if http://www.python.org/2.7 redirected to the Python 2.7.1 page. Linking to the 2.7.0 release page seems off since it is out of date, but linking to 2.7.1 also seems silly as that will become out of date as the newest release of Python 2.7 at some point as well. Can we consider coming up with some URL scheme where people can link to a version of Python that always redirects to the newest release? Bonus points if we extend this to major versions, too. =) I am asking here since the RMs will have to be okay with doing this as part of the release plan. Get the ball rolling, I say we make http://www.python.org/version/2.7 and http://www.python.org/version/2 redirect to the 2.7.1 release page, etc. Personally I would rather have http://www.python.org/2.7 redirect to 2.7.1, but since that already redirects to 2.7.0 I doubt people would be okay with the change.

I'm changing my vote on this to a +1 for two reasons: * Initially I thought this wasn't supported by Python at all but I see that currently it is supported but that support is broken (or at least limited to UTF-8 filesystem encodings). Since support is there, might as well make it better (especially if it tidies up the code base at the same time). * I still don't think it's a good idea to give modules non-ASCII names but the "consenting adults" approach suggests we should let people shoot themselves in the foot if they believe they have good reason to do so.

This broke the buildbots (R. David Murray thinks you may have forgotten to call super() in the 'payload is None' branch). Are you getting code reviews and fully running the test suite before committing? We are in RC.

Location of tests for packages

by Raymond Hettinger

Right now, the tests for the unittest package are under the package directory instead of Lib/test where we have most of the other tests. There are some other packages that do the same thing, each for their own reason. I think we should develop a strong preference for tests going under Lib/test unless there is a very compelling reason. We already have a similar preference for all Docs going under Doc/ and that has not proved to be an issue with any package maintainer. * The Windows distro has an install option to exclude Lib/test. The currrent situation with unittest works against it. * The commingling of tests with the regular code is making it more difficult to grep code while excluding tests. * Having packages create their little worlds within world is making it more difficult to find things. * For regrtest to work, there still needs to be some file in Lib/test that dispatches to the alternate test directory. This isn't a critical issue (nothing is broken) but we're a week from another release candidate, so the new Py3.2 package organization (unittest was flat in Py3.1 and its test were under Lib/test) is about to become a de-facto decision that will be hard to undo. I recommend moving it under Lib/test before everything is set in stone. Raymond P.S. I've discussed this with Michael and his preference is against going back to the Py3.1 style where the tests were under Lib/test. He thinks the current tree makes it easier to sync with Py2.7 and the unittest2 third-party module. Also, he likes grepping the regular source and tests all at once.
