ORed requirements
by Matt Good Nov. 11, 2006

Is there a way to define a requirement like "PackageA or PackageB"? AFAICT there's no syntax to specify this type of requirement, so is there some other way to handle this in setup.py? -- Matt Good

Killing Python Interpreter
by Steve Ingram Nov. 10, 2006

Nov. 10, 2006

Hello, I've got a wxPython based dialog application running under windows. No problems when I package this up using py2exe, but when I close the app the process is left running in the background (still listed in task manager). I assume that the dialog closes but the python interpreter is still running, so how do I completely kill the program?? Apologies if this is obvious, too easy to has been answered a 1000 times already, I just can't find the answer!! Thanks Steve

should I use distutils for a gnome-applet?
by Jorge Vargas Nov. 10, 2006

Nov. 10, 2006

Hi I'm writting a small gnome applet that I'll like to distribute currently I have a small handmade Makefile that will just copy all the files (3) to their destinations. but it depends on gnome-python (gconf,gnomeapplet) and pygtk, so I'll like to have some of the advantages of distutils/setuptools. although I think setuptools here is overkill distutils will be great for automatic packaging. my concern here is that I need to put the files in specific locations outside the python dirs this 2 to be exact. BONOBO_DIR = /usr/lib/bonobo/servers EXE_DIR = /usr/local/bin so my question is will I really win from hoping over to distutils or should I just stick with my Makefile?

list and remove packages with easy_install?
by Thomas Heller Nov. 9, 2006

Nov. 9, 2006

Ok, easy_install is really cool. Installing most of the packages (*) that one needs with easy_install makes the wish grow to use easy_install as a complete solution. So, why can't easy_install manage the packages that I have installed in these ways: - list the packages that I have installed - remove one of them (completely!) if I don't want to use it any longer. Ok, easy_install -m package removes if from the .pth file, but it is still there on disk. Same if I upgrade a package to a newer version; old versions are left in Lib/site-packages. It looks like all the information that is needed to implement the above two features - is there a reason why this isn't implemented? (*) The one that I rememeber which failed badly was pychecker. IIRC, I ended with batch files in Python24\scripts that contained Python code. But maybe that's pychecker's fault, not easy_install's.

easy_install and svn
by Thomas Heller Nov. 9, 2006

Nov. 9, 2006

In the easy_install docs is mentioned (at the end): Added subversion download support for svn: and svn+ URLs, as well as automatic recognition of HTTP subversion URLs How does this work? Is it possible to install a package from an svn repository, when the repository resides (read-only) at an http: URL? Thomas

Creating an "app folder" with setuptools?
by Leif Strand Nov. 8, 2006

Nov. 8, 2006

I've been trying to use setuptools as a "Pythonic Autopackage". Basically, I want users to be able install a Python package -- plus all its needed dependencies -- with a single command, without any preparatory steps, and with no questions asked. To this end, the best strategy seems to be the "app folder" strategy used on Windows. On Windows, the runtime linker/loader implicitly adds the directory containing the main '.exe' to the DLL search path. This means that regardless of any environment settings (such as PATH), DLLs put alongside the main EXE will be found -- and, with few exceptions, will override DLLs elsewhere on the system. This fact is routinely exploited on Windows: you can dump your EXE and all its needed dependencies in a single folder, and it will "just work". The Python interpreter is similar to the Windows loader in that the directory containing the main Python script is always first on 'sys.path'. This fact, combined with the awesome 'setuptools' package and easy_install's --install-dir (-d) option would seem to give me everything I need. However, there are road blocks which I can't seem to get around (without patching setuptools, that is). The chief problem seems to be that setuptools complains too much! *) It complains if the destination directory doesn't exist. *) It complains if the destination directory doesn't support .pth files or isn't on PYTHONPATH. Actually, I find the errors about .pth/PYTHONPATH to be annoying in general. On Unix, I'm accustomed to tools which simply do what they're told, be it "rm -rf *" or anything else. For example, "./configure --prefix=$HOME/foo/bar; make; make install" will create $HOME/foo/bar if it doesn't already exist, and Autoconf certainly doesn't complain about the subdirectories thus created not being on PATH or PYTHONPATH. One could argue that this amounts to a philosophical difference. But to me, the .pth/PYTHONPATH errors seem like a bug/limitation. If I tell easy_install to create a directory containing my app's scripts, plus all its (possibly "flat") egg dependencies, the resulting directory *will* work once all the dust clears, regardless of what my PYTHONPATH may contain at install time. Even in the case of .pth files, there is no way to know at install time what might work at runtime -- for example, my app's generated, top-level scripts might call site.addsitedir() themselves on behalf of the application. But perhaps I've just overlooked something. Is there a way to to tell setuptools to simply do what it's told? --Leif

distutils post processing
by Eric S. Johansson Nov. 8, 2006

Nov. 8, 2006

I'm trying to extend distutiles to do things like fix permissions etc. have a draft that works but I'm not sure how to invoke it. I'm running it after setup() but as you would expect it always run on any setup operation. How can I limit when my code run only when it's a build command? I tried following the distutiles extension instructions but it is a bit thin. some pointers would be appreciated. Thanks for your time. ---eric

setuptools: why does it install ctypes twice?
by Victor Stinner Nov. 7, 2006

Nov. 7, 2006

Hi, I'm one of the authors of pynetfilter_conntrack: http://cheeseshop.python.org/pypi/pynetfilter_conntrack http://software.inl.fr/trac/trac.cgi/wiki/pynetfilter_conntrack Here is the setup.py: http://software.inl.fr/trac/trac.cgi/browser/mirror/edenwall/pynetfilter_co… My problem is that "sudo ./setup.py install" reinstall ctypes 1.0.1 and ElementTree 1.2.6 whereas they are already installed by Ubuntu (using apt-...). Should I use different install_requires option? Current one is: install_requires = ("ctypes>=0.9.6", "IPy>=0.42", "ElementTree>=1.0") Bye, Victor Stinner PS: Please CC-me to your answers ;-) -- Victor Stinner http://www.inl.fr/

PYTHON_EGG_CACHE env setting
by Venkat Bommakanti Nov. 2, 2006

Nov. 2, 2006

Hi, I have some components, that will need to be extracted by the Python eggs runtime (pkg_resources). I understand I can use the PYTHON_EGG_CACHE env setting to specify a desired loaction for extraction. However, was wondering if is there a config file setting or another mechanism to specify this location. Would need to avoid runtime env settings it my deployment. Thanks, /venkat
