At least *.egg-info works without-a-version and will be written that way when installed in development mode. As a shortcut when possible pkg_resources would read the package name and version number from the filename and not bother looking inside the metadata file until necessary. I don't recall whether the same can be said of *.dist-info.
You will probably find that pkg_resources always does a listdir for each entry on sys.path when it runs. You might not be able to avoid that.

OK, I feel stupid now, I've been making a fuss over something that's actually not possible. I should have tested this. My apologies (in my defense, I could have sworn I remembered someone else making precisely this point sometime in the past, but I guess I'll have to put that down to advancing age and brain decay...) My apologies, I stand corrected. Paul _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org https://mail.python.org/mailman/listinfo/distutils-sig
