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 s<y ˆ||ŽStk r6}zt|ƒ|‚Wdd}~XYnXdS)N)ÚAttributeErrorr)rÚkwdsÚe)rrrr@s z!reraise_uncaught..wrapper)Ú functoolsÚwraps)rrr)rrr/src@s,eZdZdd„Zdd„Zdd„Zdd„Zd S) ÚPushBackIteratorcCsg|_||_d|_dS)N)ÚpushesÚiteratorÚcurrent)Úselfr"rrrÚ__init__JszPushBackIterator.__init__cCs|j |¡dS)N)r!Úappend)r$ÚvaluerrrÚ push_backOszPushBackIterator.push_backcCs|S)Nr)r$rrrÚ__iter__RszPushBackIterator.__iter__cCs&|jr|j ¡|_nt|jƒ|_|jS)N)r!Úpopr#Únextr")r$rrrÚ__next__UszPushBackIterator.__next__N)rrrr%r(r)r,rrrrr Isr )rrÚreÚosÚpathÚsepZ_sepÚaltsepÚcompileÚformatÚescapeZ_path_rer rrÚ Exceptionrrrr rrrrÚs
