Why did we pin to 2.2.6? 2.2.6 was the latest stable version available at the time of the release. 2.2.7 had known problems with newer libxml2 versions, but I see there's a 2.2.8 out now, which we should update to. I'm not sure about the actual dependency situation. I think it's more or less a convenience pin, as lxml is used very often in Zope related projects. We provide a known good version for it in the Zope Toolkit KGS for the same reason.

So the lxml community cannot keep up with providing binary Windows eggs. This cannot force us to stick with old and buggy versions of the software. Well... the problem, apparently, is that libxml2 doesn't (or didn't?) have suitable Windows binaries, or so I'm told. I'm also not sure the bug fixes in 2.2.5 onwards are very important in a Zope context, since they seem to deal with Python 3 compatibility mainly. What in Zope depends on lxml?

If we *are* going to use a convenience pin, then surely the ability to install on the world's most-used operating system has to be part of the convenience. ;-) If we don't use it, we shouldn't pin it, IMHO. We found this problem because the Zope KGS was overriding another KGS where we had pinned lxml to 2.2.4. I don't think Zope has any business getting in the way of that.

Windows is almost irrelevant for the market we are in - web server deployments. Erm, you think so? Maybe we should do a poll on how many Zope / Plone developers use Windows on the desktop. Or look at how many people download the Windows installer. You need a dev environment, not just deployment, and a lot of people are on Windows. Our own community is barely able to keep up providing the most basic Windows support and ensuring tests pass. As long as we don't have more community volunteers actually caring about Windows support, I won't let it be an argument to penalize the rest of the community. When the software breaks, people go elsewhere. I didn't say Windows support was easy, or any fun. But we have to decide: do we care about people who have made (or are forced to make) different technology choices than us, or do we tell them their platform is unsupported? If we don't use it, we shouldn't pin it, IMHO. We found this problem because the Zope KGS was overriding another KGS where we had pinned lxml to 2.2.4.

I don't see a problem with the few people using Windows and not installing compilers on their platforms to change one version pin. I think you're missing the point: - We shouldn't pin software we don't use. It may be well intentioned, but if we don't depend on it, we shouldn't take responsibility for it, or give the perception that we take that responsibility. - If we do depend on it, we need to make sure it works on the platforms we support. QA isn't something you do only when it's easy to do in your local dev sandbox. - If we suddenly no longer support Windows, we better have the guts to come out and say it, stop producing Windows eggs for Zope 2 stuff and explicitly state that people cannot and should not use Windows for Zope development. I hope that's not the case, though. ;) Martin ___ Zope-Dev maillist - Zope-Dev@zope.org https://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope )
