[Python-Dev] StreamHandler eating exceptions

[Guido van Rossum]

I wonder if, once PEP 352 is accepted, this shouldn't be changed so
that there is only one except clause instead of two, and it says
"except Exception:". This has roughly the same effect as the proposed
(and already applied) patch, but does it in a Python-3000-compatible
way. ATM it is less robust because it doesn't catch exceptions that
don't derive from Exception -- but in all cases where this particular
try/except has saved my butt (yes it has! multiple times! :-), the
exception thrown was a standard exception.

(Did anybody else notice the synchronicity of this request with the
PEP 352 discussion?)
