PEP 451 update
by Eric Snow Nov. 2, 2013

Nov. 2, 2013

I've had some offline discussion with Brett and Nick about PEP 451 which has led to some meaningful clarifications in the PEP. In the interest of pulling further discussions back onto this (archived/public) list, here's an update of what we'd discussed and where things are at. :) * path entry finders indicate that they found part of a possible namespace package by returning a spec with no loader set (but with submodule_search_locations set). Brett wanted some clarification on this. * The name/path signature and attributes of file-based finders in importlib will no longer be changing. Brett had some suggestions on the proposed change and it became clear that the the change was actually pointless. * I've asserted that there shouldn't be much difficulty in adjusting pkgutil and other modules to work with ModuleSpec. * Brett asked for clarification on whether the "load()" example from the PEP would be realized implicitly by the import machinery or explicitly as a method on ModuleSpec. This has bearing on the ability of finders to return instances of ModuleSpec subclasses or even ModuleSpec-like objects (a la duck typing). The answer is the it will not be a method on ModuleSpec, so it is effectively just part of the general import system implementation. Finders may return any object that provides the attributes of ModuleSpec. I will be updating the PEP to make these points clear. * Nick suggested writing a draft patch for the language reference changes (the import page). Such a patch will be a pretty good indicator of the impact of PEP 451 on the import system and should highlight any design flaws in the API. This is on my to-do list (hopefully by tomorrow). * Nick also suggested moving all ModuleSpec methods to a separate class that will simply make use of a separate, existing ModuleSpec instance. This will help address several issues, particularly by relaxing the constraints on what finders can return, but also by avoiding the unnecessary exposure of the methods via every module.__spec__. I plan on going with this, but currently am trying out the change to see if there are any problems I've missed. Once I feel good about it I'll update the PEP. That about sums up our discussions. I have a couple of outstanding updates to the PEP to make when I get a chance, as well as putting up a language reference patch for review. -eric
