No comments on the rest except to note that at this point it looks unlikely that we can make everyone happy (or even get an agreement to adopt what would be the long-term technically optimal solution -- AFAICT there is no agreement on what that solution would be, if one weren't to take porting Python 2 code into account). IOW something/sokebody has gotta give.
Indeed. This entire discussion has pushed me strongly in favor of doing a super-minimalist update to PEP 333 with the following points:
* Clarifying the encoding of environ values (locale+surrogateescape vs. latin1, TBD)
* Making the streams and all output values byte strings ('str' on 2.x, 'bytes' on 3.x), leaving everything else "native" strings ('str' on both 2.x and 3.x)
* Any other minor errata/clarifications that the folks with the requisite experience (e.g. Robert, Ian, Graham -- not an exclusive list, but at least they all have both heavy WSGI implementations under their belts and 3.x experience) think are absolutely necessary to resolve open questions for Python 3.2 WSGI implementations.
Something like that has a halfway decent chance of being able to settle and get implemented in the short timeline, and it also doesn't put Graham (mod_wsgi) in the position of coming back from vacation to a huge new spec to unravel. ;-)
(To be clear, what I'm suggesting is almost exactly what mod_wsgi does; it's just stricter on outputs than what mod_wsgi accepts, and there may be some minor issues regarding the environ encoding: mod_wsgi is probably using the latin1 approach rather than locale+surrogateescape, and I think we need to talk that one out a bit.)
Anyway, web3 is nice, but it doesn't look like it'll really fit the bill for porting applications. i.e., it's like a bike shed full of red herrings for what Python-Dev needs right now. ;-)
