Tl;dr: I woud like to change PEP-440 to remove the stigmata around dev versions that come between pre-releases and releases.
The basic scenario here is developers and CD deployers building versions from VCS of arbitrary commits. So we need to be able to deliver strictly increasing version numbers, automatically, without interfering with actual publishing of pre-release and release versions to PyPI. Today, this is fairly sane as a sort order and mechanism to deliver this: >>> v = ['1.0', '1.2.3.a1.dev1', '1.2.3.a1', '1.2.3.a2.dev1', '1.2.3.b1', >>> '1.2.3.b2.dev1', '1.2.3.rc1', '1.2.3.rc2.dev1', '1.2.3', '1.2.3.dev1'] >>> sorted(v, key=packaging.version.parse) ['1.0', '1.2.3.dev1', '1.2.3.a1.dev1', '1.2.3.a1', '1.2.3.a2.dev1', '1.2.3.b1', '1.2.3.b2.dev1', '1.2.3.rc1', '1.2.3.rc2.dev1', '1.2.3'] But it doesn't feel good using a 'strongly recommended against' order. I think the recommendation is overly strong: If we touch up the language we can make the spec clearer, and a simple example like above will speak a thousand words :). -Rob -- Robert Collins <rbtcoll...@hp.com> Distinguished Technologist HP Converged Cloud _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org https://mail.python.org/mailman/listinfo/distutils-sig
