Issue 1459476: Install PKG-INFO with packages (original) (raw)

This patch adds an 'install_egg_info' command to the distutils install process, that writes the standard PKG-INFO metadata to a file in the directory where the associated modules are being installed. The filename is based on setuptools' conventions for reading and writing such files, so that setuptools will be able to recognize distutils-installed packages as being present, and not attempt to reinstall them if they are sufficient to meet a requested dependency.

As currently implemented, Python's main setup.py causes a Python-2.5a0-py2.5.egg-info to be installed in lib-dynload. It would probably be best if it also created similar files for ElementTree, ctypes, and any other packages incorporated into 2.4 or 2.5 that were separately distributed for Python 2.3. But that feature doesn't have to be in alpha 1.
