And on Windows, presumably remove the .exe part? or are you saying 'python.exe.pythonv'?

New buildout options: checksums and allow-omitted-checksums
by Thomas Lotze 23 Mar '11

23 Mar '11

Hi, two weeks ago I asked about your opinions on a buildout option that enforces specifying (MD5) checksums for all files downloaded through buildout's download utility API. I've been discussing the subject with Christian Theune in the meantime and would like to describe a more concrete proposal now that deals with the questions raised in my previous post: In analogy with version pinning for eggs, two new options could be introduced to the buildout section: - "checksums": This option would name a config section that contains checksums for any number of resources by URL. I suggest a default value of "checksum" for it. Listing some URL with an empty checksum would explicitly express that the checksum for this resource should never be checked. I'm not sure how to structure the contents of the checksums section: URLs are not valid config keys in general (they can contain "=" characters) but I'd still like to be able to rely on the existing mechanism for overriding single options to override single checksums. Mapping arbitrary keys to whitespace-separated pairs of URL and checksum would work but sounds inelegant. - "allow-omitted-checksums": This option would specify whether resources should be downloaded that are not listed in the checksums section. I'd like to use False as this option's default value, meaning that buildout should raise a UserError if a resource is omitted from the checksums section. (Intentionally empty checksums would still be allowed.) In fact, I'm not completely happy about inventing an option with negative semantics but doing it this way is at least consistent with "allow-picked-versions". I'd like to hear other people's opinion on both the general idea and the details. Unless the whole thing gets shot down, I plan to start implementing it on a branch of zc.buildout next week. Thank you. -- Thomas

issues with namespace packages on Debian Squeeze and Python 2.6
by Manlio Perillo 23 Mar '11

23 Mar '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi. It seems I'm having some trobles with setuptools and namespace packages under Debian Squeeze and Python 2.6. One thing to say about Python 2.6 on Debian Squeeze is that "local" packages are installed under /usr/local/lib/python2.6/dist-packages/. I have tried with system default python 2.5, and namespace packages works. The same when I create a virtual environment with python 2.6. The problem seems to just be with system default python 2.6. I'm using the original setuptools (installed from sources), and not the one provided by Debian. Before trying to dig more into the issue, I would like to know if someone else is experiencing the same problem. Thanks Manlio -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk1wELgACgkQscQJ24LbaUTtNwCfe5tj21cHc2IpDbDQShoJ+7zb ml8AoI0h9IKuScKE/mZIkKZGbFC5ILka =0sg2 -----END PGP SIGNATURE-----

[issue123] [PATCH] Tolerate responses with multiple Content-Length headers
by Tres Seaver 23 Mar '11

23 Mar '11

New submission from Tres Seaver <tseaver(a)palladion.com>: Some servers (e.g., wwwsearch.sourceforge.net) apparently send multiple 'Content-Length' headers, which causes setuptools to barf trying to convert a '<length>, <length>' string to an integer. This bug breaks installing 'mechanize', which lists wwwsearch.sourceforge.net as its Download-URL, and therefore causes a bunch of Zope-related tests to fail (e.g., https://mail.zope.org/pipermail/cmf-tests/2011-March/014576.html ). The attached patch uses 'headers.getheaders('Content-Length')[0] to use only the first value found. ---------- assignedto: pje files: setuptools-multi_content_length.patch messages: 598 nosy: pje, tseaver priority: urgent status: unread title: [PATCH] Tolerate responses with multiple Content-Length headers Added file: http://bugs.python.org/setuptools/file75/setuptools-multi_content_length.pa… _______________________________________________ Setuptools tracker <setuptools(a)bugs.python.org> <http://bugs.python.org/setuptools/issue123> _______________________________________________

[issue122] Xcode 4 removes PPC compiler OS X 10.6, setup.py fails installs
by Johannes Lindenbaum 20 Mar '11

20 Mar '11

New submission from Johannes Lindenbaum <johanneslindenbaum(a)gmail.com>: Summary: OSX 10.6.x with Xcode 4 installed. Xcode 4 removes the PPC assembler from GCC. I attempted to install Fabric-1.0.0 which depended on pycrypto, during the pycrypto build there was a failure regarding "Broken Pipe". I downloaded the package separately and attempted to do the install there. Same error. I was pointed in the right direction that the broken pipe error was coming from the '-arch ppc' flag during build. Expected Result 10.6.x should not report itself as "universal" when it's no longer possible to compile for PPC. Actual Result Attempted PPC compilation fails. More detail: http://superuser.com/questions/259278/python-2-6-1-pycrypto-2-3-pypi-packag… Let me know if you require more information.

pythonv: let's also make sure the standard Python install includes an "isolated" python
by Jim Fulton 19 Mar '11

19 Mar '11

Whatever mechanism we end up with, I suggest that a standard python install include an isolated configuration. This is a common use case and should be available without having to create a virtualenv (or whatever) for each project or working directory. I'm very happy to see this work taking place.

distutils2 Forward Compatibility module
by Erik Bray 18 Mar '11

18 Mar '11

Hi all, This is my first post specifically to distutils-sig, though I've had an interest in packaging for a while (having come up with some fairly arcane schemes in the past, where no better alternatives were apparent). At any rate: I'm currently working on a plan to overhaul how a number of my company's projects are packaged and distributed. Right now they all rely on a monkey-patched, hacked up distutils that needs to go away. I'm already on top of that. But seeing as how distutils2 is going to be the "new hotness" I want to plan for at as part of my overhaul. I realize that distutils2 is still in flux, and anything I do now will have to be tweaked as development on it continues. I am fine with this, as I still intend to use Distribute as the primary installation mechanism. But I really like how distutils2 keeps all metadata in the setup.cfg file, and want to start doing that now, so that I don't have to keep two copies of everything. It should be no problem to just have my setup.py read everything it needs out of setup.cfg, but what I'm wondering is if there is already an extension to do this, or will I have to roll my own? It just seems like an obvious thing to have for transitioning to distutils2, and if it doesn't already exist it should (I will of course be happy to contribute). I should note that I don't want distutils2 itself to be a dependency for installing my packages, as it is too unstable, so directly using any machinery built into it is out of the question. Thanks for any comments, Erik
