Artifact 9a522e8d3359eee16dfe27036a4b4e35d790d0b2e623295474657c70f3bcb8f7:

• File src/OFTriple.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: 2706) [annotate] [blame] [check-ins using] [more...]
