Perhaps, but it might be a case we haven't considered. Jonathan, if 1.85.2 does
not fix the problem, I can suggest two alternatives.
If you are *not* using application-specific routing, call rewrite.select() at
the beginning of your thread. This will initialize the routes attribute to the
global values (or default values if you have no routes.py).
If you *are* using app-specific routing, I think I'll need to enhance
rewrite.select(), which I ought to do anyway.
Please let us know, first, if 1.85.2 fixes the problem.
Massimo, the reason I think it might not fix it is that thread.routes is
initialized for the current thread in main, in the rewrite.select() call. If
the app creates a new thread, it's going to have a new rewrite.thread object,
with no routes attribute.
I think.
