Using code from a dependency in setup.py
by George V. Reilly 30 May '13

30 May '13

I have a little web framework, let's call it Bread, which is used to build applications like Jam, Marmalade, PeanutButter, and other toppings. Bread both *builds* and *serves* these applications. I'm trying to figure out how to make the applications' `setup.py`s work, given the following requirements: * The apps depend upon Bread, via [setuptool's install_requires]( http://peak.telecommunity.com/DevCenter/setuptools#declaring-dependencies) * To build an application at development time, Bread reads some config and then emits assets (HTML, JS, CSS, images, etc) to the application's `output` directory. In other words, `bread devserver` reads `Jam/bread.yaml` and assembles assets in `Jam/output`, then serves the application (via Flask, but that's not otherwise pertinent). * In order to build a *deployable* Jam application, I want to invoke Bread during `python setup.py install` of Jam, to build `Jam/output`. In production, Jam should not need to build anything. * I've defined a custom `bdist_egg` setup command where `initialize_options` imports Bread, invokes the builder, then sets `self.distribution.data_files` with the appropriate tuples, before calling the base class. (And *that* was no fun to figure out.) * Right now, the `bdist_egg` is defined in Jam's `setup.py`. I want to move this and other boilerplate code into `bread.setup`, so that I can reuse it in Marmalade, PeanutButter, etc. * Potentially, this means that I'm now importing Bread code before Bread has been installed. This will surely arise in a clean install, such as a fresh virtualenv on a build machine. Can this be done with Distutils / setuptools / Distribute? -- /George V.

Good news everyone, PyPI is behind a CDN
by Noah Kantrowitz 29 May '13

29 May '13

</farnsworth> but seriously, at long last today it was my honor to throw the DNS switch to move PyPI to the Fastly caching CDN. I would like to thank Donald Stufft for doing much of the heavy lifting on the PyPI side, and to Fastly for graciously offering to host us. What does this mean for everyone? Well the biggest change is PyPI should get a whole lot faster. There are two major downsides however. There will now be a delay of several minutes in some cases between updating a package and having it be installable, and download counts will now be even more incorrect than they were before. The PyPI admins are discussing what to do about download counts long-term, but for now we all feel that the performance and availability benefits outweigh the loss. If anyone has any questions, or hears anything about issues with PyPI please don't hesitate to contact me. --Noah

Small Usability/UX Change to PyPI
by Donald Stufft 29 May '13

29 May '13

Just deployed a small update to PyPI that sets autofocus on the search form. This'll mean that you don't need to manually move to the search form upon page load and should be able to start typing immediately. -- Donald Stufft donald(a)stufft.io

Buildout can't talk to PyPI any more?
by Marius Gedminas 29 May '13

29 May '13

Could it be that recent PyPI CDN changes broke zc.buildout somehow? Witness this: $ wget http://downloads.buildout.org/2/bootstrap.py $ cat buildout.cfg [buildout] parts = zodbbrowser [zodbbrowser] recipe = zc.recipe.egg $ python bootstrap.py $ bin/buildout Error: Couldn't find a distribution for 'zodbbrowser'. Meanwhile both $ virtualenv env && env/bin/pip install zodbbrowser and $ virtualenv env && env/bin/easy_install zodbbrowser work fine. Marius Gedminas -- Those who can't write, write manuals.

PyPI CDN issues
by Andreas Jung 29 May '13

29 May '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there, after switching to the new PyPI CDN infrastructure we have seen some odd behavior with buildout fetching two hundred packages or so. Packages that are a located on PyPI have not been available to the CDN or only after some minutes. Note that these packages have not been fresh releases but older stuff. Is this a known issues or explainable behavior of the CDN?

PyPI CDN + Buildout
by Donald Stufft 29 May '13

29 May '13

There's been some issues with buildout and the new PyPI CDN. I'm going to see if I can sort this out. If anyone has buildout successfully working and sees this I'd love to know. To see if this is widespread or specific to a certain set of circumstances. -- Donald Stufft donald(a)stufft.io

Buildout (still) can't talk to PyPI
by Wes Mason 29 May '13

29 May '13

We're getting a similar issue to: http://mail.python.org/pipermail/distutils-sig/2013-May/020927.html For every new build right now, I've recorded the output from "bin/buildout" (initially bootstrap.py would also fail until I added buildout.org to allowed-hosts, as it couldn't get the egg zc.buildout==1.7.1 from pypi), and also the output of trying easy_install inside a virtualenv which suffers the same fate: https://gist.github.com/1stvamp/5669559 -- Wes

pypi protocol
by Jonas Geiregat 28 May '13

28 May '13

Hello, I'm fairly interested in the internals of pypi. Ultimately pypi is a HTTP interface to a package database. I went looking for a document, blog post or anything describing the communication between pypi client and server. I ended up reading pypiserver's source code to find out the internals. Is there a reason why there haven't been a PEP describing the pypi interface ? Regards, Jonas.

Using Scripts\foo.exe on a python which doesn't have Distribute installed?
by Matt Wilkie 26 May '13

26 May '13

Hi folks, *I've been up one side of the internet and down the other, and haven't seen this question discussed before, but as has often been the case perhaps it's just my search-fu which is weak, in which case, please kindly direct me to the answer or documentation where I can find it. Thanks :)* How to distribute a usable python program to a python which doesn't have Distribute installed? I've created a Windows Binary installer using python setup.py bdist_wininst. The setup.py contains a console script entry point, so that a Windows .exe file is created and placed in %python%\Scripts on the destination machine, as per Automatic Script Creation<http://pythonhosted.org/distribute/setuptools.html#automatic-script-creation> . However running the installed script on a machine with a virgin python install yields: D:\Py3.2.5> scripts\foo.exeTraceback (most recent call last): File "D:\Py3.2.5\scripts\foo-script.py", line 5, in <module> from pkg_resources import load_entry_pointImportError: No module named pkg_resources No module named pkg_resources<http://stackoverflow.com/questions/7446187/no-module-named-pkg-resources>tells me this error is because Distribute <http://pythonhosted.org/distribute/index.html> is not installed. How do I get my installer to include Distribute so I don't have to tell our users *"before you install our program you have to go install this other program"*? thanks in advance for your time, -matt
