Sears Russell	a078f25475	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
Sears Russell	5064e3fac2	Implemented pages that store fixed sized records efficiently, and a java-style ArrayList data structure that efficiently supports (relatively) clustered, O(1) access time expandable arrays. (This will be used for the hash implementation...)	2004-10-06 06:08:09 +00:00
Sears Russell	811bc5c710	Implemented a freespace manager that should safely allocate space, even in the face of crashes, and can reclaim unused space (unless an application opens more than one simultaneous transaction that performs allocations) ... Fixed some blob bugs (by adding extra fdatasync() calls). Began factoring out the page management code so that it is an extenstion, and a less integral part of lladd.	2004-08-21 00:03:30 +00:00
Sears Russell	b4d7883f66	Fixed regressions, major update of page / slotted interfaces in anticipation of moving LLADD towards a generic transactional page system.	2004-08-17 01:46:17 +00:00
Sears Russell	82e3fdb53a	Added (untested) support for whole-page operations, lladdhash now works.	2004-08-03 02:04:56 +00:00
