| 21:09 | Fix a bug causing the POWERSAFE_OVERWRITE device-characteristic flag to be set incorrectly if file opening is deferred. (check-in: 95d0c58d27 user: dan tags: deferred-open) | |
| 19:37 | Experimental change to os_unix.c to delay creating a database file until it is first written. (check-in: 538f7b25e4 user: dan tags: deferred-open) | |
|

| ||
| 00:52 | Add the Mandelbrot Set testcase to the "cte" testset of speedtest1. (check-in: 56febbeb57 user: drh tags: trunk) | |
| 00:18 | Add a new "testset" to the speedtest1 program: The sudoku solver. (check-in: 4677ef2f8a user: drh tags: trunk) | |

| 23:20 | Do away with the "multi-register pseudo-table" abstration. Instead, just use an OP_SCopy to load results directory from the result registers of the co-routine. (check-in: 1e64dd782a user: drh tags: trunk) | |
| 19:12 | Change the OP_Found opcode so that it expands zero-blobs prior to comparing them. Fix for ticket [fccbde530a6583b] (check-in: e2303d1b0c user: drh tags: trunk) | |
| 13:24 | Fix a harmless compiler warning in VS2013. (check-in: 83116ee3e0 user: drh tags: trunk) | |
| 13:12 | Tweaks to the generated VDBE code to make it a little easier to follow. (check-in: 129217ee91 user: drh tags: trunk) | |
| 04:24 | Enable constant expression factoring even if no tables are read and no transaction is started. (check-in: a45b87713c user: drh tags: trunk) | |
| 01:40 | Change the OP_Trace opcode to OP_Init and give it the ability to jump to the initialization code at the bottom of the program, thus avoiding the need for an extra OP_Goto. (check-in: 192dea9731 user: drh tags: trunk) | |
|
2014-02-07
| ||
| 22:21 | Add opcodes OP_InitCoroutine and OP_EndCoroutine. Use these to remove the need for separate boolean registers to record when a co-routine has finished. (check-in: 5a88b6a7ae user: drh tags: trunk) | |
| 19:33 | Fix redundant definitions of _LARGE_FILE and _LARGEFILE_SOURCE. (check-in: 4043d87979 user: drh tags: trunk) | |
| 19:26 | In the TCL bindings, make sure Tcl_AppendResult() is always terminated by "(char*)0" and not just "0". (check-in: ea4d23d1c0 user: drh tags: trunk) | |
| 19:18 | Change the OP_InitCoroutine instruction to jump over the co-routine implementation. (Closed-Leaf check-in: a522f364a6 user: drh tags: coroutine-refactor) | |
| 18:27 | Get rid of the OP_Undef and OP_IsUndef opcodes in favor of higher-level OP_InitCoroutine and OP_EndCoroutine. (check-in: 1ec0e9dd4b user: drh tags: coroutine-refactor) | |
| 13:20 | Add the OP_Undef and OP_IsUndef opcodes. With these, use the first register in the result register range as the flag to indicate EOF on an INSERT from a SELECT, rather than allocating a separate boolean register for that task. (check-in: 6fb7448550 user: drh tags: coroutine-refactor) | |
| 03:28 | More comment updates. No changes to code. (check-in: be24fbc221 user: mistachkin tags: trunk) | |
| 02:29 | Update comments in vdbe.c. No changes to code. (check-in: 1122b410de user: drh tags: trunk) | |
|

| ||
| 23:56 | Delete the OP_VerifySchema opcode. Enhance OP_Transaction to do the schema version checks that OP_VerifySchema used to do. (check-in: 2f3376ebf1 user: drh tags: trunk) | |
