|
2011-01-28
| ||
| 03:13 | Reactivate the analyze5.test script. (Closed-Leaf check-in: a2a9f6401c user: drh tags: stat2-enhancement) | |
| 01:57 | Change the weighting of binary searches on tables to 1/10th the cost of a search on an index. Change the assumed reduction in search space from a indexed range constraint from 1/3rd to 1/4th. Do not let the estimated number of rows drop below 1. (check-in: 4847c6cb71 user: drh tags: stat2-enhancement) | |
|
2011-01-21
| ||
| 15:52 | Add options to test command [do_faultsim_test] to support testing VFS implementations. (check-in: 503ad889da user: dan tags: trunk) | |
|
2011-01-20
| ||
| 02:56 | The first of a planned series of enhancements to the query planner that enable it to make better use of sqlite_stat2 histograms when the table has many repeated values. (check-in: 2cd374cd23 user: drh tags: stat2-enhancement) | |
|
2011-01-19
| ||
| 21:58 | Comment improvements in pcache1.c. No changes to code. (check-in: 9660a0a225 user: drh tags: trunk) | |
|
2011-01-18
| ||
| 17:03 | Do not use mutexes in the pcache implementation unless SQLITE_ENABLE_MEMORY_MANAGMENT is defined. This is a performance enhancement. A side effect is that pcaches will not steal pages from one another unless ENABLE_MEMORY_MANAGEMENT is set, or unless SQLITE_THREADSAFE=0. (check-in: e5ca59e63b user: drh tags: trunk) | |
