You're misunderstanding. This has nothing to do with regular python packages using eggs (which they share just fine), it is about a specific tool (zc.buildout) which manages a very tightly controlled environment (for repeatable deployments). It may also be that zc.buildout does support this (which is basically useful mostly for development where you have lots of projects going on at once all using various packages), I'm only asking.

Thanks! The package developer has fixed it and it is now up on the cheeseshop as version 0.1.2 of quadtree. -kurt > > Message: 2 > Date: Fri, 26 Jan 2007 12:03:07 -0500 > From: "Phillip J.

Yes, and it shouldn't be, since its __init__.py contains actual code, and is missing a namespace declaration. (The whole point of a namespace package is that the package itself shouldn't contain any code. After all, in a --single-version-externally-managed install, the __init__.py will not even be *there*.) So, this is a packaging error on the part of the quadtree developer(s). Most likely, quadtree is not really a namespace package and should not be declared as one, because the only reason to do that is if there are modules or subpackages under that package that are distributed *separately*.

failing to build quadtree if the package is already installed
by Kurt Schwehr Jan. 26, 2007

Jan. 26, 2007

Hi All, Sorry if this kind of thing has already been discussed. I am packaging quadtree for Mac OSX/fink (deb based package management) and am getting a failed build if the package is alread installed and I am trying to do a rebuild. Can someone point me at what needs to be changed? Is this because quadtree is a namespace?

Yes, and when I changed it to the way that works for you, it broke for someone else, so there is apparently more here than meets the eye.

setuptools requires bash, not sh.
by Anthony Baxter Jan. 24, 2007

Jan. 24, 2007

From the top of an egg file: #!/bin/sh if [[ `basename $0` = "setuptools-0.6c5-py2.4.egg" ]] then ... That syntax is a bashism, not /bin/sh. -bash-2.05b$ sh ./setuptools-0.6c5-py2.4.egg --prefix=~ ./setuptools-0.6c5-py2.4.egg: [[: not found ./setuptools-0.6c5-py2.4.egg is not the correct name for this egg file. Please rename it back to setuptools-0.6c5-py2.4.egg and try again. This is broken for Solaris (which doesn't have bash, by default), on recent Ubuntu (which has /bin/dash as /bin/sh, not bash) and any other Unix that doesn't have bash as /bin/sh. -- Anthony Baxter <anthony(a)interlink.com.au> It's never too late to have a happy childhood.

RFC: Standard Declaration of tests in eggs
by Jim Fulton Jan. 22, 2007

Jan. 22, 2007

Here is a rough draft proposal for declaring tests in eggs: Introduction ============ Software packages should have automated tests. Consumers of packages will often want to run these tests. Tools should be able to do this automatically. This proposal seeks to provide a way for automated tools to discover tests in distributions, including eggs, so that tests can be run or so that test runners can be automatically created to run the tests. Proposal ======== This proposal aims to be extremely simple. It has 2 parts: 1. A 'test_suite' entry point is defined. An egg can provide zero or more test_suite entry points. These entry points will define callable objects that can be called without arguments and that return unittest test suites. 2. An optional 'tests' extra is defined. When creating test runners or dynamically loading distributions to load tests, any distributions listed in extra requires for the 'tests' extra shall be included in the working set for the test runner.

package_data issue (chopping off characters)
by Jens Thomas Jan. 18, 2007

Jan. 18, 2007

Hello, I've just hit the problem that was mentioned in the thread with the above title (see: http://mail.python.org/pipermail/distutils-sig/2005-April/004453.html). However, the email trail seemed to have hit a dead end and it wasn't clear to me whether this had been flagged as a bug or whether it was a problem with the way that setup.py was being used. I've included a summary of the problem as I've encountered it below, but would appreciate any clarification on whether this is a bug and I need to wait for patched version, or whether it's a problem with the way I'm using setup.py and there is a change/work around I can use. Many thanks, Jens (this is being run on Ubuntu Dapper:Python 2.4.3 (#2, Oct 6 2006, 07:52:30) [GCC 4.0.3 (Ubuntu 4.0.3-1ubuntu5)] on linux2 ) I have the following directory tree dir1/ setup.py __init__.py dir2/ __init__.py doc/ test.txt And the following setup.py: #!/usr/bin/env python from distutils.core import setup setup( packages=['dir1','dir1.dir2'], package_dir = {'dir1': ''}, package_data={'dir1': ['doc/*.txt']} ) I need this done in this way because of the way that my CVS repository has been set up, with the root directory of the source (where the setup.py script lives) also being the root directory of the package, and I thought that the package_dir line above took care of that. On running the script, however, I get: jmht@csevig6:~/dir1$ python setup.py install running install running build running build_py creating build creating build/lib creating build/lib/dir1 copying __init__.py -> build/lib/dir1 creating build/lib/dir1/dir2 copying dir2/__init__.py -> build/lib/dir1/dir2 creating build/lib/dir1/oc error: can't copy 'oc/test.txt': doesn't exist or not a regular file This appears to be caused by a bit in the function get_data_files in the file: /usr/lib/python2.4/distutils/command/build_py.py specifically the line: plen = len(src_dir)+1 If len(src_dir) is 0, which it is in my case, the first character of the directory gets chopped off.
