Commit modifications if there are any.

- Run contrib/release/do-release.sh.
|

Use:

- --minor to do a minor update: $maj.$min -> $maj.$(($min + 1))
|

|
- --major to do a major update: $maj.$min -> $(($maj + 1)).0
|

This:
|

|
- adds a commit that updates the VERSION file,
|
||||||
|
- creates a signed annotated release tag for that commit, and
|
||||||
|
- pushes both the commit and the tag to the remote repository.
|
||||||
|
- Run contrib/release/upload-release.sh.
|

This creates and uploads two release tarballs.

mix -- mix 3 32-bit values reversibly.
|
|
||||||
For every delta with one or two bit set, and the deltas of all three
|
|
||||||
high bits or all three low bits, whether the original value of a,b,c
|
|
||||||
is almost all zero or is uniformly distributed,
|
|
||||||
* If mix() is run forward or backward, at least 32 bits in a,b,c
|
|
||||||
have at least 1/4 probability of changing.
|
|
||||||
* If mix() is run forward, every bit of c will change between 1/3 and
|
|
||||||
2/3 of the time. (Well, 22/100 and 78/100 for some 2-bit deltas.)
|
|
||||||
mix() was built out of 36 single-cycle latency instructions in a
|
|
||||||
structure that could supported 2x parallelism, like so:
|
|
||||||
a -= b;
|
|
||||||
a -= c; x = (c>>13);
|
|
||||||
b -= c; a ^= x;
|
|
||||||
b -= a; x = (a<<8);
|
|
||||||
c -= a; b ^= x;
|
|
||||||
c -= b; x = (b>>13);
|
|
||||||
...
|
|
||||||
Unfortunately, superscalar Pentiums and Sparcs can't take advantage
|
|
||||||
of that parallelism. They've also turned some of those single-cycle
|
|
||||||
latency instructions into multi-cycle latency instructions. Still,
|
|
||||||
this is the fastest good hash I could find. There were about 2^^68
|
|
||||||
to choose from. I only looked at a billion or so.

--------------------------------------------------------------------
|
|

hash() -- hash a variable-length key into a 32-bit value
|
|
||||||
k : the key (the unaligned variable-length array of bytes)
|
|
||||||
len : the length of the key, counting by bytes
|
|
||||||
level : can be any 4-byte value
|
|
||||||
Returns a 32-bit value. Every bit of the key affects every bit of
|
|
||||||
the return value. Every 1-bit and 2-bit delta achieves avalanche.
|
|
||||||
About 36+6len instructions.
|
|
||||||
|
|
||||||
The best hash table sizes are powers of 2. There is no need to do
|
|
||||||
mod a prime (mod is sooo slow!). If you need less than 32 bits,
|
|
||||||
use a bitmask. For example, if you need only 10 bits, do
|
|
||||||
h = (h & hashmask(10));
|
|
||||||
In which case, the hash table should have hashsize(10) elements.
|
|
||||||
|
|
||||||
If you are hashing n strings (ub1 **)k, do it like this:
|
|
||||||
for (i=0, h=0; i<n; ++i) h = hash( k[i], len[i], h);
