Preliminary version of logical logging linear hash. (No latching yet, and there are some bugs re-opening a closed hash.) 2004-10-18 18:24:54 +00:00
Implemented a linear hash from scratch. Concurrency hasn't been done, but it's probably correct in the single thread case. 2004-10-12 02:44:47 +00:00			`#include <lladd/crc32.h>`

Starting to rip the old jbhash implementation out, and replace it with a linear hash implementation. In particular, I've implemented (sort of) an iterator for linear hash, and (sort of) ported libdfa to linearhash.c I say 'sort of' since this functionality is broken with this commit. On the other hand, CVS should build now, and the tests under lladd will pass. libdfa's new tests don't pass at the moment. 2005-01-10 03:02:02 +00:00			`unsigned int max_bucket(unsigned char tableBits, unsigned long nextExtension);`
