ObjFW  History of src/OFHash.h of cec0f072f847e4ab

OFHash is too generic, as this protocol is for cryptographic hashes. It
also solves the ambiguity of the +[hash] method (which is now
+[cryptoHash]), which conflicted with -[hash] on the class itself,
resulting in classes conforming to OFHash not being able to be used as a
key in an OFDictionary. check-in: [951f530aee] user: js, branch: trunk, size: 0

This increases the required GCC version from 4.0 to 4.6 (exception:
Apple GCC, which already supports this with >= 4.0 starting with OS X
10.5). Since even GCC 4.6 is really old by now, there is no point in
still supporting something even older and making the code ugly because
of that. While some hardware and OS support was dropped from GCC 4.6
compared to GCC 4.0, there is nothing in there that would be an
interesting target with the exception of BeOS maybe - but a port to BeOS
can also be achieved using the Haiku support. The other dropped OSes are
mostly old versions of OSes while newer ones are still being supported
(and those newer versions of those OSes still support the same
hardware). file: [c1bb376104] check-in: [48980f2297] user: js, branch: trunk, size: 2207 [annotate] [blame] [check-ins using] [diff]

This is useful to calculate many hashes without allocating new objects. file: [3407d4c3db] check-in: [7c27db9fe0] user: js, branch: trunk, size: 2192 [annotate] [blame] [check-ins using] [diff]

The only places where BOOL is left are those where they are required by
the ABI. file: [ecafca2322] check-in: [c5ef582958] user: js, branch: trunk, size: 1834 [annotate] [blame] [check-ins using] [diff]

Also adds a missing OF_RETURNS_INNER_POINTER. file: [b9ba1a51a3] check-in: [0b32d65e0c] user: js, branch: trunk, size: 1839 [annotate] [blame] [check-ins using] [diff]
