It's not compliant with the WSGI 1 spec, which calls for write() to
On the one hand, you could say that anybody who gives a crap about
the spec wouldn't use write() to begin with. But then, on the other,
if we ignore the spec ourselves, we're hardly in a position to
complain about their behavior. ;-)
Anyway, Graham raised the difficulty of making a compliant adapter as
an argument for having a WSGI 1.1 rather than jumping straight to
2.0, and I just wanted to show that it's not that difficult in
principle to make a fully WSGI 1.0-compliant 2-to-1 adapter, at least
if you cheat and use greenlets to handle the less well-behaved WSGI 1 apps.
The hairiest bits of defining 2.0 have more to do with nailing down
the whole bytes/unicode/native circus, the input stream API,
etc... most of which I hope we can do in the errata for 1.0.
