There can often be a decent amount of coding time placed into that function, and for naught, if the format is non-salted. Yes, the function IS used, on non-salted, and must return 1, simply to pass self tests, but a stub function simply returning 1 would be just as valid as a complex function. There could even be checks put into self-test to warn that a non-default cmp_all is being used in a non-salted format, and error out if default IS being used in a salted format. Something to look at in bleeding. ---- jfoug@....net wrote: > > However, digging deeper into JtR's actual running, I found out something I did not know before. cmp_all is ONLY called for salted types. I thought cmp_all was always called. The cmp_all does get called, always, within the self test code, but the expectation there, is that cmp_all should return true, which this version does. > > Magnum, I wonder if self-test code should mirror this logic (not calling cmp_all for non-salted), or if possibly all non-salted formats should have their cmp_all functions removed, and replaced with fmt_default_cmp_all ?
