This is really evil (mainly because of `__getattr__`). Therefore this class originally had to be derived from `BaseException` instead of `Exception`. But because I removed relevant `hasattr` from the code base, we can now switch back to `Exception`. :param base: return values of sys.exc_info().

Usage: Put ``@rethrow_uncaught`` in front of the function which does **not** suppose to raise `AttributeError`. AttributeError is easily get caught by `hasattr` and another ``except AttributeError`` clause. This becomes problem when you use a lot of "dynamic" attributes (e.g., using ``@property``) because you can't distinguish if the property does not exist for real or some code inside of the "dynamic" attribute through that error. In a well written code, such error should not exist but getting there is very difficult. This decorator is to help us getting there by changing `AttributeError` to `UncaughtAttributeError` to avoid unexpected catch. This helps us noticing bugs earlier and facilitates debugging. c sDzˆ|i|¤ŽWSty>}zt|ƒ|‚WYd}~n d}~00dSr)ÚAttributeErrorr)rÚkwdsÚerr r r@sz!reraise_uncaught..wrapper)Ú functoolsÚwrapsrr rr r/src@s,eZdZdd„Zdd„Zdd„Zdd„Zd S) ÚPushBackIteratorcCsg|_||_d|_dSr)ÚpushesÚiteratorÚcurrent)Úselfr'r r r Ú__init__JszPushBackIterator.__init__cCs|j |¡dSr)r&Úappend)r)Úvaluer r r Ú push_backOszPushBackIterator.push_backcCs|Srr ©r)r r r Ú__iter__RszPushBackIterator.__iter__cCs&|jr|j ¡|_nt|jƒ|_|jSr)r&Úpopr(Únextr'r.r r r Ú__next__UszPushBackIterator.__next__N)rrrr*r-r/r2r r r r r%Isr%)rr#ÚreÚosÚpathÚsepZ_sepÚaltsepÚcompileÚformatÚescapeZ_path_rer rrÚ Exceptionrrrr%r r r r Ús
