pip caches downloads by default, many systems are starting to utilize that cache in order to stop repeat downloads of the same file. This would make it so that if you had a shared pip cache amongst many archiectures or platforms (which people are starting to do, especially with sharing caches with virtual boxes running on their own machines or services like Travis-CI) you'd only have to download that file from PyPI once ever. Looking at a few of the top projects on PyPI in terms of download count we have: Of those, only really lxml is large enough that adding a second or third or fourth copy of the .so is a really meaningful increase in size and since we wouldn't be making a "fat wheel" mandatory lxml could just decide not to build one. As far as I can tell we don't actually optimize for maximizing the amount downloading (otherwise we'd use something better than a .zip file). > Since you need special support for such ZIP files (either using dlopen > hacks or temporarily extracting them), you might as well deal with > the platform dependencies in that handler.

There are other reasons as have already been mentioned, this is just yet another reason (and on it's own I'd agree it's not a sufficiently compelling use case), but when I see a pattern of things which all need the same thing then that speaks to me that it should live someplace centrally instead of having each one reimplement it. > I'm not saying that having a central solution is wrong.

I don't care if it gets added as part of this ticket, another ticket, or as a PEP. I'm just listing where it'd be useful for the kinds of things I do. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22980> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
