Regardless of whether we end up mandating a source tree -> sdist -> wheel -> install path or if we support two paths, source tree -> sdist -> wheel -> install and source tree -> wheel -> install, I don’t think it’s likely we’re going to ever get to a place that sdists are an optional or non-standard artifact or interface. I think it is mandatory that we treat (and recognize) that a sdist is different than an arbitrary directory and that they may (or may not) have a structure that matches what it looks like on disk. It is entirely possible (and likely) that at some point in the future we will have a new sdist format that looks less like someone just zipped up their VCS checkout and more like a structured format. ----------------- Donald Stufft PGP: 0x6E3CBCE93372DCFA // 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org https://mail.python.org/mailman/listinfo/distutils-sig
