ObjFW  Artifact [182fa6d94f]

Artifact 182fa6d94f2798e22d74d203dae5705fc53d597dbdce9c3cd1ee2c7b3db53547:

• File src/OFXMLAttribute.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: 4204) [annotate] [blame] [check-ins using] [more...]
