A better solution to people failing package correctly (missing MANIFEST, whatever) is to test your package prior to uploading to PyPI. Then you don't need mutable files, your release process becomes more robust, your releases become more robust, and the ecosystem in general becomes more robust.
Further more I would still argue that the benefits to the community outweigh the ability for people to skimp on the release process. Either you are doing your releases adhoc, in that case you don't have much of a release process to begin with, so doing it over again to bump it up one more isn't a huge deal, or you have a large release process and testing the package before distributing it should be a part of it. > > > (Even though I believe it would be acceptable to cover that particular use > > case by giving a grace period of when you can re upload). > > > Can't we just leave dealing with that problem to the package authors ? > It's their responsibility, not PyPI's. > > In my opinion No. PyPI is acting as the central repository, it is it's responsibility to take a reasonable effort to protect the people that depend on it. The current solution doesn't just make end developers at risk from a bad author breaking their well tested software. It also puts the security of their software under the the author's watch. Author of a particular package's credentials get leaked/stolen/whatever? suddenly my software is now possibly vulnerable to whatever person did it decides to upload. It puts the integrity of my (proverbial my) software in the hands of a disparate group of authors who may or may not have the same stringent testing that I do. Any python application that get's installed from PyPI is at risk of mysteriously breaking, even with a "known good" configuration. These bugs are often hard to track down, and very confusing and difficult to determine why they are occurring when they never did before. > > -- > Marc-Andre Lemburg > eGenix.com (http://eGenix.com) > > Professional Python Services directly from the Source (#1, Jan 30 2012) > > > > Python/Zope Consulting and Support ... http://www.egenix.com/ > > > > mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ > > > > mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ > > > > > > > > > > > ________________________________________________________________________ > > ::: Try our new mxODBC.Connect Python Database Interface for free ! :::: > > > eGenix.com (http://eGenix.com) Software, Skills and Services GmbH > Pastor-Loeh-Str.48 > D-40764 Langenfeld, Germany.
