/* Bucket expansion has the effect of doubling the number of buckets

* items will distribute more or less evenly into the new buckets
|
||||
* (the extent to which this is true is a measure of the quality of
|
||||
* the hash function as it applies to the key domain).
|
||||
*
|
||||
* With the items distributed into more buckets, the chain length
|
||||
* (item count) in each bucket is reduced. Thus by expanding buckets
|
||||
* the hash keeps a bound on the chain length. This bounded chain
|
||||
* length is the essence of how a hash provides constant time lookup.
|
||||
*
|
||||
* The calculation of tbl->ideal_chain_maxlen below deserves some
|
||||
* explanation. First, keep in mind that we're calculating the ideal
|
||||
* maximum chain length based on the *new* (doubled) bucket count.
|
||||
* In fractions this is just n/b (n=number of items,b=new num buckets).
|
||||
* Since the ideal chain length is an integer, we want to calculate
|
||||
* ceil(n/b). We don't depend on floating point arithmetic in this
|
||||
* hash, so to calculate ceil(n/b) with integers we could write
|
||||
*
|
||||
* ceil(n/b) = (n/b) + ((n%b)?1:0)
|
||||
*
|
||||
* and in fact a previous version of this hash did just that.
|
||||
* But now we have improved things a bit by recognizing that b is
|
||||
* always a power of two. We keep its base 2 log handy (call it lb),
|
||||
* so now we can write this with a bit shift and logical AND:
|
||||
*
|
||||
* ceil(n/b) = (n>>lb) + ( (n & (b-1)) ? 1:0)
