| 18:06 | Fix the speedtest1.c test program to set the worker thread count using the threads pragma. (check-in: 2ab4b5adc6 user: drh tags: threads) | |

| ||
| 23:18 | Refactor the sqlite3PcacheFetch() routine into three separate routines, which are significantly faster overall and about 100 bytes smaller in size as well. (check-in: bdb6e4978d user: drh tags: trunk) | |

| 17:37 | When determining whether or not a partial index is usable, do not assume that the cursor number assigned to each table in the query is the same as its index in the FROM clause. Fix for ticket [98d973b8f5]. (check-in: fcebca166f user: dan tags: trunk) | |
| 14:14 | In the sqlite3_context object, keep a pointer to the result value rather than storing the result value in the sqlite3_context object and using memcpy() to move the value back into its register after the function returns. This runs faster and saves over 500 bytes of code space. (check-in: 6c1ee3e388 user: drh tags: trunk) | |
| 03:28 | Factor out the exception paths from sqlite3ValueToText() into a separate function so that the main routine is much faster for the common case of no required type or encoding conversions. (check-in: 1624916c6e user: drh tags: trunk) | |
| 00:50 | Performance enhancement in sqlite3VdbeMemNulTerminate(). (check-in: f94cacc393 user: drh tags: trunk) | |
|
2014-08-26
| ||
| 15:06 | Change the page cache so that a new sqlite3_pcache object is allocated as soon as the page cache is opened, not delayed until the first fetch request. This give a noticable performance boost. The interface between pager and the page cache has changed slightly, which might break ZIPVFS. (check-in: f1f94a971e user: drh tags: trunk) | |
|
2014-08-25
| ||
| 23:44 | Remove the SQLITE_CONFIG_WORKER_THREADS configuration parameter. The number of worker threads in the sorter is now determined only by the PRAGMA threads=N setting. (check-in: e3305d4b4e user: drh tags: threads) | |
| 22:43 | Merge the CAST operator enhancements from trunk. (check-in: 6c8f86e4e0 user: drh tags: threads) | |

| 21:11 | Minor changes to the CAST logic to make it more testable. (check-in: 1ad70ec550 user: drh tags: trunk) | |
| 20:21 | Test cases added for using unary "+" and CAST operators on the RHS of range constraints and verifying that STAT3/4 can use those constraints. (check-in: 42505e5a81 user: drh tags: trunk) | |
| 20:11 | Allow CAST expressions and unary "+" operators to be used in the DEFAULT argument of an ALTER TABLE ADD COLUMN and to be understand on the RHS of range constraints interpreted by STAT3/4. This involves a rewrite of the implementation of the CAST operator. (check-in: 91d8a8d0b7 user: drh tags: trunk) | |
| 18:29 | In cases where stat4 data is available but cannot be used because the rhs of a range constraint is too complex a expression, fall back to using the default estimates for number of rows scanned. (check-in: e06dc6f0c3 user: dan tags: trunk) | |
| 15:13 | Query or change the maximum number of worker threads allowed on each database connection separately using the "PRAGMA threads" command. (check-in: 29c5e8a7c9 user: drh tags: threads) | |
| 13:27 | Merge the recent performance enhancements implemented on trunk into the threads branch. (check-in: dfdc900f5d user: drh tags: threads) | |
