Sears Russell	61249c29a7	New "default" buffer manager that aims to replace the current one, but ... without deadlocks. Still need to track down a memory corruption bug that this introduces, or exercises.	2007-03-08 07:56:53 +00:00
Sears Russell	ef43d5e4ce	Implemented log truncation.	2006-04-14 03:45:26 +00:00
Sears Russell	54ba9b0347	Refactored bufferMananger / pageCache, so that bufferMananger handles loading an unloading pages, and pageCache only implements the replacement policy. ... Also, used memprof to detect and remove all memory leaks (at least all memory leaks that are encountered by check_transactional2), and fixed a number of misuses of the pblHash.	2004-07-27 01:04:35 +00:00
Sears Russell	422198418a	bufferMananger is (really!) re-entrant now, performed big refactoring to prevent deadlocks, check_transactional2 ran overnight without coring, w/ 25 threads, and 10000 allocate/write/reads per thread. (The whole test suite was run in a loop...)	2004-07-23 20:21:44 +00:00
Sears Russell	9712e291e6	Moved page.h and some of the logging headers out of the public API.	2004-07-14 21:25:59 +00:00
Sears Russell	af152bd08e	Logwriter can now handler partial log entries correctly (it ignores them) ... Buffer Mananger no longer steals pages pre-maturely Alloc is an operation, and correct. Caching broken out into a new module Wrote a utility to translate a log file into human-readable ascii.	2004-06-30 01:09:57 +00:00
