|12:41||Change the pager locking mechanism so that we don't have to write page 1 to the journal and to the database unless it actually changes. (CVS 419) (check-in: 480eef1a user: drh tags: trunk)|
|01:11||Add the ability to turn of calls to fsync() using the "synchronous" pragma. Increased the default cache size from 100 to 2000 and made the "cache_size" pragma persistent. (CVS 418) (check-in: 414da4af user: drh tags: trunk)|

|18:59||VIEWs are bound to tables when they are used, not when they are first entered. This works around the problem of what to do if a table is deleted that a view refers to. (CVS 415) (check-in: 6121e5ab user: drh tags: trunk)|
|03:42||Fix a memory leak in expression processing. (CVS 414) (check-in: dfe431c9 user: drh tags: trunk)|

|20:41||Pager optimization: do not write or journal free pages. This results in a 2x performance gain for large INSERTs and a 5x performance gain for large DELETEs. (CVS 410) (check-in: cf1ebcfb user: drh tags: trunk)|
|19:00||Change the btree node balancers to sort nodes into accending order. This improves insert and delete speed by 25%. (CVS 409) (check-in: abbb999d user: drh tags: trunk)|
|17:04||Subquery flattening is implemented and passes all regression tests. We still need to add addition tests to the suite to further exercise the flattener, however. (CVS 408) (check-in: d5d3e79c user: drh tags: trunk)|
|04:10||Bug fix when -DMEMORY_DEBUG is off. (CVS 407) (check-in: e14b0c82 user: drh tags: trunk)|
