Re: source-less python

Alexander Kanavin

Generally we slim down python installations by not installing all of
the standard library, and rather having precise dependencies for
specific modules. Can you illustrate the kind of space savings that
can be gained in actual numbers?

Another issue is that this should be supported upstream and in the
wider python community. Is it?

Just as a small reference since I raised some doubts and questions in Buildroot community on this: there has been also some troubles to understand the correctness or not there (as I found some packages with problems due to this source-less management) and this then sparked, besides discussions in the Buildroot mailing list (roughly end of July / beginning of August if someone interested searching there), also an issue to the Python community, which albeit some discussion I think never arrived to a concrete conclusion. This is the issue: (see also the linked one maybe)

These are just my 2 cents to this discussion, then of course the Python experts will probably chime in and describe the official/discussed position of Yocto regarding to this, but just felt like mentioning that although Buildroot is somehow offering this right now (and likely mostly works as well!), it's not really a so clean and/or agreed solution.

I was wondering if there has been talk about support for source-less python on an image. Installing py and pyc files doubles the size of python on the rootfs. I can imagine this being implemented as an image feature.
I know that in buildroot it is supported.
Was this discussed and decided against? Is this an open issue?
I have a working patch that implements this. I can submit it for review.
