Documentation : At-most-once Semantics

dipakyadav

This is from page 14 of the documentation.

An idempotent operation is an operation that, if executed twice, has different effects than if executed once.

Shouldn't it be the other way around.

An idempotent operation is an operation that , if executed any number of times has the same effects/results.

Btw, if i have some stuff like this, should this be posted under bugs or under comments/suggestions.

thanks,

Hmmm... I think that's exactly what the descriptions says. It doesn't matter whether you execute the operation once, twice, or n times -- the outcome is always the same, as long as the operation is executed at least once.
So, I think your description and mine say exactly the same thing.

Depends on whether it's a bug or a suggestion If in doubt, use bugs.

Cheers,

Umm, Michi, if the original quote is correct (and I don't have the doco
open at the moment) then your descriptions are exactly opposite.

Oops, how terribly embarrassing... Dense as I am, I finally got it: the book says "different" when it should say "the same". I'll fix that for the next version.

So, rest assured, "Bug Reports" is indeed the correct forum to report this ;-)

Cheers,

Now, Bruce, congratulations, that's a very diplomatic way of pointing out that I'm up shit creek

Rely on Bruce to rub it in...
