Thanks for confirming.  I was wondering myself about introducing a new name in order to avoid the mess of the breaking change.  I would just recommend we make sure to deprecate the old ones that are named poorly.  I'll enter a ticket in a bit.

Thanks!

Yea, this does not seem correct, but IMHO they are both named terribly. In order to avoid a breaking change how about we deprecate these, and replace them with 'request-larger-than' and 'request-smaller-than' to make it clearer exactly what is being tested?

These two predicates from undertow are named/implemented backwards.  The "max" should be ensuring the provided value is at least as small or smaller and the "min" should be ensuring the provided value is at least as big or bigger.  But here are the descriptions of each one.

MinContentSizePredicate
Predicate that returns true if the Content-Size of a request is below a given value.


MaxContentSizePredicate
Predicate that returns true if the Content-Size of a request is above a given value.

So to spell it out, if someone uses the following predicate:

max-content-size(5)

That means they are saying the maximum content size is 5 bytes.  So, here's a quick truth table:
  • If content length is 4 bytes -> should return true (under the max)
  • if content length is 5 bytes -> should return true (at the max, but not over)
  • if content length is 6 bytes -> should return false (over the max)
But this is the exact opposite of how these predicates have been implemented.  The javadoc matches the behavior, but not the name.

Can I get a quick confirmation this is, in fact, backwards before I enter a ticket and/or pull request.  Note, this will be a breaking change to fix.

Thanks!
