two setup scripts
by Chris Jerdonek May 18, 2012

May 18, 2012

I have an open-ended question about the idea of creating two setup scripts for a project: one for end-users (e.g. installing), and another for all other use cases (e.g. project development). Here are a few reasons I came across for considering something like this: The first is that if the project needs to support, say, Python 2.4 through Python 3.2, then having two setup scripts would let you require (and develop against) Python 2.7 for the developer version, while supporting all versions only for the simpler end-user version. This would also let you do things like import from the project itself in the developer version of your setup script, a process that would break if running the setup script using Python 3 (assuming you are using 2to3 for Python 3 support). The second is that I have a pre-processing step that requires using pandoc to generate setup()'s long_description from README and HISTORY files in markdown format prior to uploading to PyPI, and I don't want end-users to need pandoc. I am currently dealing with this in code, but it would be nicer to have simpler code with fewer "if blocks." The third is simply separation of concerns. This approach raises the following questions: (1) Which setup commands should each version of the script support? (2) Which arguments to setup() are required and/or used for each command? I would also like to know (2) independent of creating two setup scripts. For example, I mentioned long_description above. The long_description seems to be available in places like PKG-INFO and in the DOAP xml file exposed on PyPI, so is it necessary to pass long_description, etc to setup() for any setup command other than sdist (which creates PKG-INFO), or is it also necessary to pass that metadata to setup() even with the upload and install commands? Thanks, --Chris

{dist-info} category in resources = ...
by Daniel Holth May 17, 2012

May 17, 2012

My take on installing entry_points.txt is to add a {dist-info} category in [files] resources = to copy extra files into the .dist-info dir... How do I write entry_points.txt when it is given as an argument to setup(entry_points=...)? Should I write a build command hook to write the file and a setup_hook to append the new file to [files] resources = so it will finally be copied?

total uninstall of setuptool on MacOS X by consequence of manual install
by Arturo Rinaldi May 16, 2012

May 16, 2012

I installed some time ago on MacOS X Lion the python-setuptools script with the shell command */$ sudo sh setuptools-0.6c11-py2.7.egg/* then I uninstalled any .egg installed and removed the script itself with /*$ sudo easy_install -m setuptools* /which in turn removed the /easy_install.pth /file//in the //Library/Python/2.7/site-packages// directory. Now by running the command /ls/ in that directory i get : */README setuptools.pth vboxapi-1.0-py2.7.egg-info setuptools-0.6c11-py2.7.egg vboxapi//* can i remove /setuptools.pth and //setuptools-0.6c11-py2.7.egg /too ? I'd like also to perform a total clean uninstallation so i searched in my HD and i found that i still have the files : *//usr/bin/easy_install /usr/bin/easy_install-2.5 /usr/bin/easy_install-2.6 /usr/bin/easy_install-2.7 /* and the following directories (i attach the output in a text file). I also installed python-numpy through it and then uninstalled the package itself in the standard way. Which directories and files can i delete without harming my system (so i can totally switch to macports) ? Thx in advance. Regards, Arturo

command_hooks and Python-3.3.0a3???
by Rob Healey May 15, 2012

May 15, 2012

Greetings: Do you know if the command_hooks patch will get into Python-3.3.0a3 before the end of next week when it is suppose to be released? I truly hope so because I am stuck because command hooks are not working for me??? I hope that I am NOT being too pushy as I know that Eric is go busy already! -- Sincerely yours, Rob G. Healey

Questions about install-prefix in distutils.
by Robert Park May 15, 2012

May 15, 2012

Hello, I found this email from some years ago: http://mail.python.org/pipermail/distutils-sig/2009-September/013284.html I find myself now having the same problems. My lazy solution so far has been to simply install the data files into the same module directory, and then I just do os.path.join(os.path.dirname(__file__), 'datafile.txt') when I want to access a data file. This was ok when I only had one data file, but my project is expanding and I need something more robust and organized. I tried to look at other projects similar to mine to see how they handled this situation, and it turns out that none of them use distutils! They are all using autotools, and while that's a very cumbersome set of tools, it allows them to pre-process the source files so that the source files know where they've been installed to in a very straightforward way. So I'm just wondering, is this build_py override still the best way to accomplish this? Has this functionality been rolled into distutils in the last 3 years? How are folks handling this situation now-a-days? Note that I don't use setuptools so I'm looking for a pure-distutils solution. Thanks! -- http://exolucere.ca

Confounded by unhelpful error message.
by Robert Park May 12, 2012

May 12, 2012

So, I'm using distutils to build RPMs on Fedora. I've had success with this in the past but now I'm running into a problem and I'm not sure how to fix it since the error message is an outright lie! I start like this, naturally: $ python setup.py bdist_rpm running bdist_rpm writing 'build/bdist.linux-x86_64/rpm/SPECS/GottenGeography.spec' running sdist running check warning: sdist: standard file not found: should have one of README, README.txt reading manifest template 'MANIFEST.in' not writing to manually maintained manifest file 'MANIFEST' creating GottenGeography-1.0.1 creating GottenGeography-1.0.1/data creating GottenGeography-1.0.1/gg creating GottenGeography-1.0.1/po making hard links in GottenGeography-1.0.1... hard linking README.md -> GottenGeography-1.0.1 [.... blah blah blah ....] Creating tar archive removing 'GottenGeography-1.0.1' (and everything under it) copying dist/GottenGeography-1.0.1.tar.gz -> build/bdist.linux-x86_64/rpm/SOURCES building RPMs rpm: build/bdist.linux-x86_64/rpm/SPECS/GottenGeography.spec: No such file or directory error: Failed to execute: "rpm -q --qf '%{name}-%{version}-%{release}.src.rpm %{arch}/%{name}-%{version}-%{release}.%{arch}.rpm\\n' --specfile 'build/bdist.linux-x86_64/rpm/SPECS/GottenGeography.spec'" And it just stops right there. Note that the very second line of output indicates that it is creating this file. Indeed: $ ls -lh build/bdist.linux-x86_64/rpm/SPECS/GottenGeography.spec -rw-r--r--. 1 robru robru 1.3K May 3 02:04 build/bdist.linux-x86_64/rpm/SPECS/GottenGeography.spec The file is there, with exactly the indicated path. What is going wrong here? Google has turned up nothing, although it is admittedly very difficult to search for since "No such file or directory" is a very common error message and there's not a lot else to go on here. The only thing I can think of is that there's a distutils dependency that I don't have installed, as this computer is a fresh install since the last time this worked for me. But rpm and distutils are both installed so I'm not really sure what exactly could be missing. Help? Thanks. -- http://exolucere.ca

Need some advice on extending install_data
by Robert Park May 12, 2012

May 12, 2012

So, I'm using distutils with some success lately, and I've borrowed some code that extends install_data to compile .po (translation) files into .mo files to be used by the system to display the translated strings. It looks like this: https://github.com/robru/gottengeography/blob/master/setup.py It seems fairly straightforward to me and there's only a tiny amount of magic involved. However, upon testing this, I've discovered this behavior: 1. When running `setup.py install`, the mo files are correctly compiled and installed to the system. 2. When running `setup.py bdist`, the resulting tarball will correctly compile and include the mo files for distribution. 3. When running `setup.py bdist_rpm`, the resulting RPM file does not contain any trace of any .po or .mo files. I'm not sure why bdist_rpm is the odd man out here, but it seems like I'm overlooking something simple. Unfortunately the API reference seems a little light on details: http://docs.python.org/distutils/apiref.html#module-distutils.command.bdist So I'm not entirely clear on how I should go about overriding bdist_rpm to achieve the same thing as is done by overriding install_data. At this point I am reviewing the distutils source code directly but it's been less instructive than I'd hoped. Any ideas? Thanks. -- http://exolucere.ca

easy_install runnable in a sandbox environment?
by Rick van der Zwet May 10, 2012

May 10, 2012

I am having issues in running easy_install in a sandbox environment (chroot with python2.7 under FreeBSD 9.0-RELASE, without /dev mount). easy_install is sourcing tempfile, which requires /dev/urandom to be present, as seen in the backtrace: brahm# sh -x setuptools-0.6c11-py2.7.egg + basename setuptools-0.6c11-py2.7.egg + [ setuptools-0.6c11-py2.7.egg = setuptools-0.6c11-py2.7.egg ] + exec python2.7 -c 'import sys, os; sys.path.insert(0, os.path.abspath('\''setuptools-0.6c11-py2.7.egg'\'')); from setuptools.command.easy_install import bootstrap; sys.exit(bootstrap())' Traceback (most recent call last): File "<string>", line 1, in <module> File "/usr/local/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg/setuptools/command/easy_install.py", line 12, in <module> File "/usr/local/lib/python2.7/tempfile.py", line 34, in <module> from random import Random as _Random File "/usr/local/lib/python2.7/random.py", line 881, in <module> _inst = Random() File "/usr/local/lib/python2.7/random.py", line 97, in __init__ self.seed(x) File "/usr/local/lib/python2.7/random.py", line 111, in seed a = long(_hexlify(_urandom(16)), 16) OSError: [Errno 2] No such file or directory: '/dev/urandom' Quite some time ago, their has been comments in the changelog (06.c4) stating that running easy_install without /dev/urandom should be possible: Fixed not allowing os.open() of paths outside the sandbox, even if they are opened read-only (e.g. reading /dev/urandom for random numbers, as is done by os.urandom() on some platforms). While this was back in 2006, I was wondering what the current state of affairs which regards of requiring the /dev/urandom as of today? Am I looking at a feature request, bug report or design limitation? Br. /Rick -- http://rickvanderzwet.nl
