In terms of API design, I'd prefer a flag to os.urandom() indicating a preference for - blocking - raising an exception - weaker random bits
+100 ;-) I proposed exactly this 2 days ago, 5 hours after Larry's initial post. ''' I think the 'new API' should be a parameter, not a new function. With just two choices, 'wait' = True/False could work. If 'raise an exception' were added, then 'action (when good bits are not immediately available' = 'return (best possible)' or 'wait (until have good bits)' or 'raise (CryptBitsNotAvailable)' In either case, there would then be the question of whether the default should match 3.5.0/1 or 3.4 and before. ''' Deciding on this then might have saved some hurt feelings, to the point where two contributors feel like disappearing, and a release manager must feel the same. In any case, Guido already picked 3.4 behavior as the default. Can we agree and move on? -- Terry Jan Reedy
