fail more completely by deleting dbhash from sys.modules if bsddb can't be loaded - prevents second import later from succeeding spuriously - mostly of use in regression tests where the module might get imported more than once 2001-01-25 09:47:00 -04:00			`import sys`

added __all__ lists to a number of Python modules added test script and expected output file as well this closes patch 103297. __all__ attributes will be added to other modules without first submitting a patch, just adding the necessary line to the test script to verify more-or-less correct implementation. 2001-01-20 15:54:20 -04:00			`__all__ = ["error","open"]`
