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
switched to region allocator, but TpageAlloc currently grabs its own region... 2006-07-20 01:29:39 +00:00			`//void headerPageInitialize(Page * p);`
