For example, I can browse the 'Zope3' framework category and find a lot of Zope3-related software now. I wish more software were aptly classified with this Trove classifier so I could find more (all!) Zope3 software tehre.
i just uploaded the z3c.widget 1.0.6 egg and am trying the use-cases below.
because of this mix you might end up in getting the wrong egg. or not finding a egg you downloaded a few days ago. in case pypi is down you're totally stuck.You're stuck either way, even if you'd be using download.zope.org/ distribution. The key is to mirror the PyPI simple index. That's what ppix (or actually it's success zc.mirrorpypislashsimple) is all about.This is a non-issue I think.
o.k. fine, you're actually right.i'm wondering why i couldn't fine zope.app.wsgi = 3.4.0b1dev_r75415 after 3.4.0 was released a few days ago.
probably someone in [philikon, ctheune, J1m, baijum] removed the egg?we nailed the version to 3.4.0b1dev_r75415 (and i have still this egg in my cache), but it disappeared from the rest of the world. this should never happen for released eggs, they should be considered read-only imho.
sorry for blaming pypi/setuptools for this :)
well, i understand that the stability of pypi is much better lately and the simple interface, the and ppix mirrors make the index lookup much faster as well.but for me there are still two remaining issues:- the eggs are hosted on cheesehop as well, it's not easy (commandline) to host the egg externally or to specify a mirror to use when pulling the eggs. that's not acceptable for production deployments.I think it's really easy. Just use Jim's mirror software and point buildout to that different index. That's one line in buildout.cfg.Again, seems like a non-issue.
i'm not talking about the index, i mean the actual download. http:// download.zope.org/ppix/z3c.widget/ still points to pypi.python.org
is there a way to change this? mirror it?
- by default "setup.py sdist bdist_egg register upload" hides the old releases, which is not acceptable as we nail all versions for deployments. if someone releases a new version, the older ones disappear and buildout (with nailed versions) stops and complains not finding the egg.It doesnt' disappear from the simple index. It just disappears from the "human" index, which I think is a good idea. It doesn't make sense to show people a billion releases. setuptools and zc.buildout (which both nowadays use the simple index) will obviously need to know about the odl releases.This is a non-issue :).
before we don't have a solution for the two points above i have objections to register the packages on pypi and prefer to add download.zope.org/distribution to my find-links.if there is an easy solution for it, enlighten me :)Human discoverability is *very* important. If you have doubts about depending on PyPI, fine. I won't mind a backup location (though I hate download.zope.org/distribution. It has piled up so many crappy eggs by now with no way of deleting them...).But please don't take the human discoverability away from it all. I thikn that's what PyPI is great for. Provided you actually make it worthwhile and have meaningful package metadata in setup.py.Bis morgen :)
bis morgen :) jodok
