templates for .cfg in zc.buildout
by Tarek Ziadé Dec. 24, 2007

Dec. 24, 2007

Hello, I have posted a message earlier about having a way to play with the environment in cfg files (http://www.nabble.com/zc.buildout-:-Playing-with-environment-in-cfg-files-t…) we came up with a simple way to deal with this, using templates for our cfg files. See iw.buildout: https://ingeniweb.svn.sourceforge.net/svnroot/ingeniweb/iw.buildout/trunk/i… This reduces a lot the number of cfg files we need when we work over applications that are installed under win32 and developed by linux users for instance. I would like to propose this enhancement for inclusion in zc.buildout if you think it's a good idea, to avoid maintaining another package on the top of zc.buildout. I guess we could refactor it so it uses either simple string templates, either cheetah templates. ++ Tarek -- View this message in context: http://www.nabble.com/templates-for-.cfg-in-zc.buildout-tp14487365p14487365… Sent from the Python - distutils-sig mailing list archive at Nabble.com.

Two problems with setuptools
by Dmitry Vasiliev Dec. 23, 2007

Dec. 23, 2007

Hello, Today I've encountered the two problems related (?) to setuptools (version 0.6c6 on Ubuntu Linux): 1. For tests and install my package requires the same packages so I write: setup( ... tests_require=["Package1", "Package2"], install_requires=["Package1", "Package2"], ) It seems OK but the problem arrives if I want to test package (python setup.py test) and then install it (python setup.py install). At the test phase the required packages will be downloaded and placed in the current directory. But at the install phase it seems setuptools will be fooled by the previously downloaded packages and doesn't install them correctly. 2. For my setup I need customize 'install_scripts' and 'install_data' commands. I've placed my customized commands in a separate package, create lazily populated dict-like object which import desired modules by request and write: setup( ... cmdclass=aLazilyPopulatedDictLikeObject, setup_requires=["Package"], ) It works fine except the case when I want to place some options in setup.cfg. For 'install_data' it works as expected, but for 'install_scripts' it seems the configuration parses before the required package will be downloaded and my additional options for 'install_scripts' doesn't work. -- Dmitry Vasiliev (dima at hlabs.spb.ru) http://hlabs.spb.ru

easy_install and packages with both egg and non-egg distributions
by Papa Eric Dec. 21, 2007

Dec. 21, 2007

Hello, From the documentation, unless the --upgrade option is used (or, I suppose, a version specifier given), easy_install is supposed to be content with distributions already installed on sys.path or site-packages. But is it true also when an egg distribution is available for this same package? My problem: I have a dependency on a package xxx which is already installed (as a subdirectory of site-packages). If I put "install_requires = ['xxx']" in some setup.py, the egg will be downloaded. If I try "easy_install xxx" directly, this will force the egg distribution, too. I don't want the egg version because it does not work, import fails on "zipimport.ZipImportError: can't find module 'xxx'" (yet unzipping the egg the xxx packages is there, if anyone has an idea of what may be missing...). Also, if I remove the installed egg to used the existing distribution of xxx, my installed package now works well, except the script installed via entry_points, which seem to expect an egg in any case. So I cannot just "correct" the distribution by removing the wrong egg. The current solution I have found is not formally declare the dependency and advise to install xxx before... Is this the expected behaviour? I'm using python 2.5.1, windows xp, setuptools 0.6c7. Thanks for any help.

setuptools docs mention "distutils.log" ?
by zooko Dec. 20, 2007

Dec. 20, 2007

Folks: The setuptools page suggests that authors of revision control plugins can use "distutils.log.warn", but my version of distutils has no such name "log". http://docs.python.org/dist/module-distutils.log.html Regards, Zooko

(A valid filename for pytftpdblib, version 0.2.0, would be pyftpdlib-0.2.0.tar.gz.) You need to use "setup.py sdist" to generate your source distribution, then it will have the right filename. (You'll also be able to use "setup.py sdist upload" to upload it to PyPI in that case.)

pypi and easy_install

Can someone point me in the right direction Either Pyrex, setuptools, or both, are outdated on your system. Check to make sure you have the very latest of both.

setuptools and automating deployment of dependent packages
by Jeremy M. Jones Dec. 13, 2007

Dec. 13, 2007

I am working on some deployment and testing issues with an application at my job. We have one parent package that depends on a number of other packages. I'm working to create an automated build system that checks out the latest revision of each package from Subversion and creates an egg for each (where each has the svn revision number in its version number). The problem is that I'd like to specify exact version numbers in the parent's setup.py for each child package, but I don't know the child svn revision numbers until I start checking things out and I'd really like to automate the process. I could just create a dependency for each child package that states >= some version and when I easyinstall it, it should grab the latest child package from the web server. But that kind of doesn't accomplish what I wanted to do with having a parent package that is specifically tied to some version of a child package. The way that I am considering making this work is to script an update of the setup.py for any package that has child packages that it is checking out of svn. This feels like a big ol' hack. Another alternative is to create a config file (yaml or something else) that setup.py pulls versions from and update that when a parent package becomes aware of a child package's svn revision numbers. So, my questions are: 1. Is there a better way of doing what I'm trying to do than having to hack on setup.py files or modify yaml files? 2. If there's not, how can I tell what version a child package now has (with svn revision number) to know how update the setup.py or config file or what-not? 3. Is there a way to get at the data (version and dependency information is what I'm after) in setup.py? 4. How can I create my own pypi in order to upload eggs to after I've created them? Any assistance anyone could provide would be most appreciated. - jmj

buildouts upgrades in production
by Tarek Ziadé Dec. 13, 2007

Dec. 13, 2007

Hello We are happily using zc.buildout to deploy our Python softwares (mainly zope) in production. The offline mode is very helpfull to create a media with a prepared buildout to deploy the thing on a server that has no web access (this is most of the time the case i guess) Now I am working on the best ways to prepare upgrades for the production and I try to find a way to avoid recreating a big tarball again just for a few changes. My guess is that a snapshot of the download-cache and eggs directory is enough, so a diff can be made to "upgrade" a production server with a tarball of the two directories and the new .cfg But I was wondering if someone had similar experiences already, and maybe a simple, better way ?
