bandersnatch 1.0
by Christian Theune April 9, 2013

April 9, 2013

Hi, good news: I have cut a 1.0 release for "bandersnatch", the PEP381 client that I started as an overhaul of "pep381client" at PyCon 2013. Here's the news: * I decided to use a "requirements.txt" to support PIP-based environments.[1] * Markus Zappke Gründemann noticed that I was missing the actual license text and provided me with a pull request. * Overhauled README, hopefully a bit easier to read. * The next step on my agenda is to get all the existing public mirror operators on board so that we hopefully will see more "green bar" moments when visiting pypi-mirrors.org. Who can help? Cheers, Christian [1] There is some integration magic to automatically generate the requirements.txt, have it available for different releases on bitbucket, etc. See "buildout.py" and "release.py" in the package code. Not for the faint of heart. I also added a jenkins job that verifies the requirements.txt, installs the sdist package and runs tests from there.

G'day AIM: i'm trying to use Drive API with Python 2.7.3 to read and write files. PROBLEM: is with the install of "easy_install" (ironic, i know) 1. I have enabled the drive api 2. I can see that the google client library must be there because the files are in c:/program files/python/scripts BUT when i type easy_install into cmd window it is not recognised -i have tried running the file: easy_install-2.7.exe -i have updated the directory path in my computer/properties/advanced/ to include C:/Program Files/Python/Scripts - i have downloaded the PyWin32 installer (i am running XP) for Python 2.7 http://stackoverflow.com/questions/4016151/how-to-use-pythons-easy-install-… mentions that "you should see that your winpexpect package has been installed correctly." winexpect. where is this located? how is this done? thanks!

buildout 2 craziness: "upgrading" to distribute 0.6.26 and using site-packages from another python install
by Chris Withers April 9, 2013

April 9, 2013

Hi All, This is driving me nuts, I hope someone can help. So, pre-amble, I'm on a Mac, I have a few python installations, the ones in play here are: buzzkill:xlutils chris$ which python /Library/Frameworks/EPD64.framework/Versions/Current/bin/python buzzkill:xlutils chris$ which python2.6 /usr/local/bin/python2.6 buzzkill:xlutils chris$ which python2.7 /Library/Frameworks/EPD64.framework/Versions/Current/bin/python2.7 The buildout I'm working with is here: https://github.com/python-excel/xlutils/blob/master/buildout.cfg My python2.7 has a site-packages xlrd (it's EPD, which includes a bunch of packages), so I'm using python2.6 on this machine, since it doesn't (it's a plain source install on python). Okay, so, as you'll see from github above, I have the latest bootstrap.py, and the initial bootstrap looks fine: buzzkill:xlutils chris$ python2.6 bootstrap.py Downloading http://pypi.python.org/packages/source/d/distribute/distribute-0.6.35.tar.gz Extracting in /var/folders/m6/tsd59qsj7pd_lldh4mhwh6kh0000gn/T/tmpxnVlCD Now working in /var/folders/m6/tsd59qsj7pd_lldh4mhwh6kh0000gn/T/tmpxnVlCD/distribute-0.6.35 Building a Distribute egg in /var/folders/m6/tsd59qsj7pd_lldh4mhwh6kh0000gn/T/tmpg4hxVn /var/folders/m6/tsd59qsj7pd_lldh4mhwh6kh0000gn/T/tmpg4hxVn/distribute-0.6.35-py2.6.egg buzzkill:xlutils chris$ cat bin/buildout #!/usr/local/bin/python2.6 import sys sys.path[0:0] = [ '/Users/chris/buildout-eggs/distribute-0.6.35-py2.6.egg', '/Users/chris/buildout-eggs/zc.buildout-2.1.0-py2.6.egg', ] import zc.buildout.buildout if __name__ == '__main__': sys.exit(zc.buildout.buildout.main()) Okay, so now try running that buildout: buzzkill:xlutils chris$ bin/buildout Upgraded: distribute version 0.6.26; restarting. Generated script '/Users/chris/LocalGIT/xlutils/bin/buildout'. Develop: '/Users/chris/LocalGIT/xlutils/.' Develop: '/Users/chris/LocalGIT/xlutils/../xlrd' Traceback (most recent call last): File "/var/folders/m6/tsd59qsj7pd_lldh4mhwh6kh0000gn/T/tmpwnpB08", line 13, in <module> exec(compile(open('/Users/chris/LocalGIT/xlutils/../xlrd/setup.py').read(), '/Users/chris/LocalGIT/xlutils/../xlrd/setup.py', 'exec')) File "/Users/chris/LocalGIT/xlutils/../xlrd/setup.py", line 18, in <module> from xlrd.info import __VERSION__ ImportError: No module named info While: Installing. Processing develop directory '/Users/chris/LocalGIT/xlutils/../xlrd'. An internal error occured due to a bug in either zc.buildout or in a recipe being used: <snip> File "/Users/chris/buildout-eggs/zc.buildout-2.1.0-py2.6.egg/zc/buildout/easy_install.py", line 129, in call_subprocess % repr(args)[1:-1]) Exception: Failed to run command: '/usr/local/bin/python2.6', '/var/folders/m6/tsd59qsj7pd_lldh4mhwh6kh0000gn/T/tmpwnpB08', '-q', 'develop', '-mxN', '-d', '/Users/chris/LocalGIT/xlutils/develop-eggs/tmpUg8rV8build' Okay, so, a few comments: - "upgrading" to distribute version 0.6.26 from 0.6.35. Whu?! - The xlrd in /Users/chris/LocalGIT/xlrd certainly does have an info module. Now the really crazy bit: buzzkill:xlutils chris$ cat bin/buildout #!/usr/local/bin/python2.6 import sys sys.path[0:0] = [ '/Users/chris/buildout-eggs/zc.buildout-2.1.0-py2.6.egg', '/Library/Frameworks/EPD64.framework/Versions/7.3/lib/python2.7/site-packages', ] import zc.buildout.buildout if __name__ == '__main__': sys.exit(zc.buildout.buildout.main()) Come again?! Why is site-packages from a *different python installation* ending up in bin/buildout? Any help here would be very gratefully received...

Towards a bandersnatch release - updates, PIP, contacting mirror owners
by Christian Theune April 8, 2013

April 8, 2013

Hi, I spend some more time on bandersnatch and I'm ready for a stable release, I guess. Updates ------------ * Add a specific user agent to XML-RPC and plain HTTP calls * Add a specific user agent to the logging to support debugging * Provide a default (10s) network timeout and a config option to customize * Clean up README PIP --- I'd be happy to cut a release now. Holger Krekel asked me whether I could ensure that bandersnatch is pip installable. Looking through the PIP documentation I don't see how I can make a simple "pip install bandersnatch" repeatable. Especially if someone would run a public mirror I would prefer if they would use an installation method that makes their deployment repeatable. From my own experience and background I would prefer buildout in the following style: $ hg clone https://bitbucket.org/ctheune/bandersnatch $ cd bandersnatch $ hg co 1.0 $ virtualenv-2.7 . $ bin/python bootstrap.py $ bin/buildout $ bin/bandersnatch Thoughts? Contacting mirror owners ---------------------------------- All this work is directed towards getting the existing official mirrors back to a "green bar" situation soon. Can someone help me contact the existing mirror owners to convince them to switch tools? Also, I'd be happy to run a couple vhosts around the world to extend the network if some people throw in some money (gittip?) Cheers, Christian

Re-uploading packages
by Christian Theune April 5, 2013

April 5, 2013

Hi, when developing bandersnatch I saw some checksum errors for the md5sums of downloaded package files that I didn't understand. I just saw another one and just want to check back whether this is true: I can go to PyPI, delete a package version, and upload a different file later. True? This would explain that I can see a file that I downloaded successfully changing it's hash over time. Feels like a bad idea to me, but I guess this is part of the "PyPI doesn't have an oppinion" deal … Christian

"packaging-user" mailing list?
by Marcus Smith April 4, 2013

April 4, 2013

Some of the pypa people have been discussing beginning a "packaging-user" mailing list. - It would be open to *any* packaging or install user issues. - It would be on python.org - pip/virtualenv would use it instead of our "virtualenv" list - Other projects could(would) use it too: Setuptools (old and new), Distribute, wheel, buildout, bento? etc... I think python users would appreciate the simplicity of this, and the support would be better too I think. distutils-sig would maintain it's current focus as a place for development discussions. thoughts?

Help with buildout
by John Anderson April 4, 2013

April 4, 2013

I'm trying to use buildout to pull in 4 github repositories and combine their wsgi applications together using paste's urlmap. A few things aren't working the way I expect and so I'm looking for some more information: This is my buildout.cfg: https://github.com/sontek/notaliens.com/blob/master/buildout.cfg 1. I had to declare a [pyramid] section that pulls in Pyramid with the zc.recipe.egg recipe so that it would drop the entry_point scripts in the generated bin/ folder. Is there a way for it to do this from dependencies declared in my install_requires in setup.py rather than being declared in the buildout? 2. The 2nd problem is after I run buildout, I'm not able to import paste.deploy: I see the egg in my sys.path: bin/py >>> import sys >>> sys.path <cut> '/home/sontek/code/test_notaliens/ notaliens.com/eggs/PasteDeploy-1.5.0-py2.7.egg', but if I try to import from it: >>> from paste.deploy import loadserver Traceback (most recent call last): File "<console>", line 1, in <module> ImportError: No module named deploy PasteDeploy is defined as a dependency and gets pulled in properly but for some reason the interpreter isn't seeing it. any ideas?
