44a766a7f6 * Fixed a race condition. Pages that were merged during writeback were 
set clean and unpinned while the slow handle was writing them back.
This allowed other threads to come in, and read the old version of the
page from disk.

* Fixed performance bug: When considering pages for writeback, start
  after the end of the last flushed page (not the first flushed page)

* Honor "max_fast_handles".

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...

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.
