2013-12-20
| ||
| 14:48 | Allow any arbitrary expression as the filename in an ATTACH statement, including functions and subqueries. (check-in: df70a1f3 user: drh tags: trunk) | |
| 13:11 | Simplify the accumulator reset for aggregate query processing so that it uses a single multi-register OP_Null rather than a separate OP_Null for each register. (check-in: 2c7fd9b0 user: drh tags: trunk) | |
|
2013-12-19
| ||
| 17:04 | Do not inject OOM faults into SQLITE_FCNTL_COMMIT_PHASE_TWO file-control invocations. It causes problems for test scripts. (check-in: 8eb28d23 user: dan tags: trunk) | |
| 16:26 | Make sure errors encountered while initializing extensions such as FTS4 get reported out from sqlite3_open(). This fixes a bug introduced by check-in [9d347f547e7ba9]. Also remove lots of forgotten "breakpoint" commands left in test scripts over the years. (check-in: ca3fdfd4 user: drh tags: trunk) | |
| 14:34 | Remove an unneeded column-cache flush in aggregate SELECT and an unreachable branch in the INSERT logic. (check-in: ffa092e1 user: drh tags: trunk) | |
| 02:56 | Omit an unnecessary OP_Null opcode from UPDATE. (check-in: 72d11133 user: drh tags: trunk) | |
| 02:23 | Omit one or more pointless instructions that occur in between OP_NoConflict and OP_Halt. (check-in: 61e2f357 user: drh tags: trunk) | |
|
2013-12-18
| ||
| 18:44 | Remove an unnecessary column-cache flush operation. Add code to trace the column cache when compiled with SQLITE_DEBUG and using PRAGMA vdbe_addoptrace=ON. (check-in: 58704ed1 user: drh tags: trunk) | |
| 16:27 | Remove an unnecessary column-cache flush. Add another test case to the speedtest1.c program to accentuate the benefit of not flushing the cache at that point. (Closed-Leaf check-in: 97fdfc6b user: drh tags: column-cache-debug) | |
| 15:11 | Show changes to the column cache when PRAGMA vdbe_addoptrace=ON is set. (check-in: 4c6a659c user: drh tags: column-cache-debug) | |
|
2013-12-17
| ||
| 16:32 | Add evidence marks and additional test cases for the printf() SQL function. (check-in: 93121d30 user: drh tags: trunk) | |
| 16:10 | Add the printf() SQL function. (check-in: a1bb62f9 user: drh tags: trunk) | |
| 15:58 | Fix the formatting of %c in the printf() SQL function. (Closed-Leaf check-in: 3375571a user: drh tags: printf-sql-function) | |
| 15:03 | Add the printf() SQL function. (check-in: 6db7052e user: drh tags: printf-sql-function) | |
|
2013-12-14
| ||
| 13:44 | Allow the SQLITE_DETERMINISTIC flag to be ORed into the preferred text encoding of application-defined functions, to mark the function as deterministic. (check-in: 5716fc23 user: drh tags: trunk) | |
|
2013-12-13
| ||
| 20:45 | Performance optimizations in the pager_write() routine of pager.c. (check-in: bc5febef user: drh tags: trunk) | |
| 19:48 | Reduce the number of calls to the subjRequiresPage() routine inside of pager. (check-in: e50ff39a user: drh tags: trunk) | |
| 19:35 | Create and use a new pager interface sqlite3PagerUnrefNotNull() that works just like sqlite3PagerUnref() but guarantees that its argument is not a NULL pointer. (check-in: e00f37e2 user: drh tags: trunk) | |
| 18:50 | Enhance the pcache1PinPage() routine so that it called much less often and runs much faster in the cases when it is actually called. (check-in: a845779c user: drh tags: trunk) | |
| 16:42 | Avoid unnecessary calls to sqlite3_free() from within sqlite3VXPrintf(). (check-in: e2a8b280 user: drh tags: trunk) | |
| 16:23 | Simplication and optimization of error message handling. (check-in: 9d347f54 user: drh tags: trunk) | |
|
2013-12-11
| ||
| 15:47 | Add the SQLITE_FCNTL_SYNC and SQLITE_FCNTL_COMMIT_PHASETWO file-controls and have the pager call them at appropriate times. This is needed in order to enable ZIPVFS to do multi-file atomic commits. (check-in: 552f94d5 user: drh tags: trunk) | |
| 14:17 | Merge in the latest trunk changes. (Closed-Leaf check-in: 9ff4dfe1 user: drh tags: zipvfs-multifile-commit) | |
| 14:00 | Fix a bug in the shell ".import" command: Do not end the field when an escaped double-quote occurs at the end of a CRNL line. (check-in: 5e239ecd user: drh tags: trunk) | |
| 12:02 | Remove an unreachable conditional inserted by the previous check-in. (check-in: 3e1d55f0 user: drh tags: trunk) | |
| 11:00 | Fix harmless compiler warnings. (check-in: a7e5fcd6 user: drh tags: trunk) | |
