Hello

Here's a wrapup of the Distutils-SIG discussion we had on the "static metadata" topic. I realize that it's a good thing to send in. python-dev such wrapup on distutils design decisions, to keep everyone informed and get more feedback when required. I will try to do it for every upcoming changes that are not going in a PEP process (when it's not a 'big' change). The rate of such mails should not be very high. (around 1 mail in python-dev for +150 mails in distutils-SIG) If you feel that what we are about to change in distutils is wrong, you can go ahead and help us by participating in Distutils-ML, so we keep one and only one media for these discussions. The four sentences summary for people in a hurry: Getting metadata of a distribution that is not. installed means running its setup.py. This means. downloading the whole archive, and running. third party code on your system. To avoid it, we are adding a [setup] section in. setup.cfg where you can express the package metadata statically. Conditional sections, specific to some system. can be added to add some specific fields in [setup]. At the end, you will be able to get metadata fields without running any third-party code, and possibly get only the distribution setup.cfg for this.

While it's a good idea to put up some form of meta-data into an index, I wonder why you are using setup.cfg for this.

setup.cfg has traditionally been used to configure distutils, not to define meta-data. As such you wouldn't want to put such a configuration file up on PyPI.

Wouldn't it be better use a new file for this (with the same syntax), e.g. metadata.cfg ?! This would then just contain the meta data that needs to be published.

Thanks,
