Cascade and environ['wsgi.input'] issue

[w31rd0]

When cascading apps environ is copied but environwsgi.input? points at the same place. Hence once read, environwsgi.input? remains empty for the rest of apps in a cascade. I found this when was trying to cascade multiple Pylons apps. This probably could be solved by replacing environwsgi.input? with sort of StringIO and seek(0)-ing it before each try.

Fixed in r7020; but there aren't any tests for paste.cascade so I'm not too confident of the fix yet :(

Replying to ianb:

Sometimes crashes with

ValueError: invalid literal for int()

at this line

length = int(environ.get('CONTENT_LENGTH', '0'))

(CONTENT_LENGTH is present in environ, but equals an empty string).

I've attached the diff, which avoids the ValueError?.

This actually was fixed a couple days ago in trunk

Sorry for being so obtrusive :) But there is still a problem: environwsgi.input? doesn't get seek(0)-ed before the last app in cascade. So you probably need the following fix (I'll attach the diff).
