Artifact 7b9ce87bc693479679d9d80b7d9464bac5571ba1771a809be7a3e1779dcbd62c:

• File src/OFDNSQuery.m — part of check-in [aeb403a1ed] at 2020-10-10 14:27:37 on branch trunk — OFObject: Change type of -[hash] to unsigned long

  The internal hash is still 32 bit in most places, but this way, it is at
  least not baked into the API and ABI and can be upgraded later, should
  that ever be necessary. (user: js, size: 2577) [annotate] [blame] [check-ins using] [more...]
