05ad97b37b Was releasing log_read_mutex without obtaining it first... 2007-04-20 07:13:18 +00:00
Sears Russell
362b1036de Changed CLR log format so that it is identical to update entries. The old format pointed back to an earlier 
entry in the log, complicating truncation significantly.  The new format copies log entries into their CLRs,
and is somewhat redundant, as redo and undo information is stored in the CLR, but the undo information will
never be used...

Sears Russell
61249c29a7 New "default" buffer manager that aims to replace the current one, but

05275bbe5a Tracks ranges in O(m log n) time. 2007-01-24 18:25:38 +00:00
Sears Russell
c2fa9913b1 Added partial implementation of range tracking for pinning arbitrary 
regions.  Currently, tracks regions, and is O(m log(n)) for each
operation, where m is the number of transition points per range, and n
is the number of transition points in the system.  A transition point is
a place in memory where the pincount changes.

5b56370980 Fixed append. (It wasn't calling updateEOF, as it should have been. Also, updateEOF assumed start_pos was zero) 2006-11-22 05:04:48 +00:00
Sears Russell
802eeb33e7 New non-blocking implementation, with backpressure. Still doesn't handle overlapping writes. (Multiple writes to the same region is OK though.) 2006-11-21 06:50:12 +00:00

8481e9cdd6 non_blocking is closer to working (it now flushes writes out in the background). This required some api changes. It still passes unit tests, but it's losing data on close()... 2006-10-28 03:33:02 +00:00
