zc.buildout and broken product distros
This one had biten me a few months ago and now again. A customer project includes the PloneSurvey product and downloads the package from www.plone.org plone.recipe.distros . No it doesn’t. If you try to download the package you get a 0 bytes tar file. Probably a left over from the file migration in the Plone Software Center.
http://plone.org/products/plone-survey/releases/1.2.0/plonesurvey.tar (don’t use this)
And buildout doesn’t complain. You only spot it later when you see Broken product references in the instance logs and see a “Product Removed” notice in the portal_quickinstaller in a site where it still was installed. Sigh.
