| 11:38 | Performance optimization and stronger assert()s in the comparison opcodes. (check-in: e0305e64 user: drh tags: trunk) | |
| 06:33 | For TCL extension: Adjust provided "gui" command, and document it. For shell: Separate shell variables from binding parameters, mainly so they live longer, in the shell DB. Add .vars dot command to reflect this separation, and specialized for shell variables. Much code shuffling to share code between .parameters and .vars commands. (check-in: fa492ff5 user: larrybr tags: cli_extension) | |
| 01:12 | Only invoke sqlite3VdbeClearObject() from a single location, so that the compiler is more likely to in-line the code. Performance increase and size reduction. (check-in: c6947a96 user: drh tags: trunk) | |
|
2022-04-03

| 22:35 | Performance optimization in the sqlite3VdbeHalt() routine. (check-in: 9564d72a user: drh tags: trunk) | |
| 20:39 | Performance optimization and size reduction in the OP_Halt opcode. (check-in: 21948e6e user: drh tags: trunk) | |
| 19:13 | Omit the Vdbe.runOnlyOnce flag (simplifying the prepared statement implementation) and accomplish the same result by adding an "OP_Expire 1 1" opcode to prepared statements that would normally have runOnlyOnce set. (check-in: 6e20e1c4 user: drh tags: trunk) | |
| 10:42 | Performance optimization and slight size reduction in the OP_Transaction opcode. (check-in: 7bee8c19 user: drh tags: trunk) | |
|
2022-04-02
| ||
| 22:47 | Expand the getVarint32() macro in a few places, as the C-compiler seems to be able to optimize better when that macro is expanded manually. (check-in: cd4fe34b user: drh tags: trunk) | |
| 20:08 | Fix harmless compiler warnings. (check-in: 8a3a3486 user: drh tags: trunk) | |
| 19:21 | Ensure that a zero-blob does not cause in invocation of memcpy() with a zero length and a NULL source pointer. (check-in: 35441eb5 user: drh tags: trunk) | |
| 15:19 | Minor loop optimization in OP_MakeRecord. (check-in: 4350983b user: drh tags: trunk) | |
| 14:30 | In-line the sqlite3VdbeSerialPut() routine into the OP_MakeRecord opcode. This allows some duplicate comparisons to be omitted, resulting in a size reduction and performance increase. (check-in: 6f4d6f21 user: drh tags: trunk) | |
|
2022-04-01
| ||
| 21:01 | The putVarint32() macro does not optimize well. So expand it into in-line code in places were performance is an issue. (check-in: 390c239e user: drh tags: trunk) | |
| 20:39 | Loop optimization in the OP_MakeRecord opcode. (check-in: 47a61fbd user: drh tags: trunk) | |
| 20:19 | It is not necessary to de-ephermeralize the output registers in the OP_ResultRow opcode. Omit that step for a size reduction and performance increase. (check-in: 8a07745a user: drh tags: trunk) | |
| 19:13 | There is no need for sqlite3_step() to check for an OOM condition prior to starting up. (check-in: 44be7f46 user: drh tags: trunk) | |
| 19:04 | Omit the Vdbe.doingRerun field for a slight size reduction and performance gain. (check-in: e93297a9 user: drh tags: trunk) | |
| 18:45 | New macro ROUND8P() which works like ROUND8() but assumes that the input is already a multiple of the size of a pointer. It becomes a no-op for 64-bit machines, giving a small size reduction and speed boost. (check-in: d126f304 user: drh tags: trunk) | |
| 18:19 | Provide and use a version of sqlite3VdbeFreeCursor() that guarantees the cursor pointer is not NULL. This saves a few bytes of code space and a few CPU cycles. (check-in: cb5e6f8e user: drh tags: trunk) | |
| 17:23 | Remove an unnecessary branch from sqlite3VdbeReset(). (check-in: a7d79560 user: drh tags: trunk) | |
| 17:01 | Refactor the Vdbe.iVdbeMagic field into Vdbe.eVdbeState. Split the RUNNING state into separate RUNNING and READY. This gives a size reduction and performance increase. (check-in: 5a50a42f user: drh tags: trunk) | |
| 16:22 | Avoid a harmless uninitialized variable warning in PRAGMA incremental_vacuum. (check-in: 6d976f90 user: drh tags: trunk) | |
| 15:31 | Have the sqlite3_context object carry the encoding for the prepared statement that it represents, so that sqlite3_result() and similar can set the encoding according to the prepared statement, even if the database encoding has changed. dbsqlfuzz c409b10d0a6bccf78ab00f47e1d29d42ee5b3565 (check-in: d4e19314 user: drh tags: trunk) | |

| 21:15 | Split out the RUN state into separate READY and RUN states. (Closed-Leaf check-in: d698826b user: drh tags: vdbe-state-refactor) | |
| 20:04 | Rename Vdbe.iVdbeMagic to eVdbeState. Remove unnecessary states. This is a preliminary step toward splitting RUN_STATE out into several other states. (check-in: ff91191d user: drh tags: vdbe-state-refactor) | |
| 16:09 | Fix harmless compiler warnings. (check-in: b916087a user: drh tags: trunk) | |
| 11:12 | Refinement to [3f9887d4a58cbfdb]: The SQLITE_CONSTRAINT error should only be returned if the prepared statement came from sqlite3_prepare_v2(). The legacy sqlite3_prepare() is documented to return only SQLITE_ERROR. (check-in: f2d9262e user: drh tags: trunk) | |
| 04:05 | Make CLI build after an incomplete rename completed. (check-in: 4f11e639 user: larrybr tags: cli_extension) | |
| 03:45 | For TCL extension: Add Tk and means to run it, optionally. Implement ScriptSupport interface. For shell: Get scripting support thru an object interface like the others. Rename OutMode* to Export*. For both: Provide a way to pass arguments to an extension upon load and get them into TCL's argv. (check-in: d2446e50 user: larrybr tags: cli_extension) | |

| 17:56 | Faster and slightly smaller implementation of sqlite3Step(). (check-in: c6901a8c user: drh tags: trunk) | |
| 17:36 | Small size reduction and performance increase in sqlite3FinishCoding(). (check-in: 9248ce50 user: drh tags: trunk) | |
| 11:12 | Incorporate fix noted as absent by forum post https://sqlite.org/forum/forumpost/aefd62fcc7ebd8b6 (check-in: 336851b1 user: larrybr tags: branch-3.38) | |

| 22:57 | In setResultStrOrError(), if the input string pointer is NULL and hence the value gets set to an SQL NULL, then the Mem.enc field is uninitialized. So do not read it. This is a harmless OSSFuzz/ASAN found problem. (check-in: 47d0b1c4 user: drh tags: trunk) | |
| 21:11 | For TCL extension: Cleanup TCL library interaction and interpreter management. Group code into more purpose oriented functions. Add .unknown dot command, delegating to TCL commands with "dot" names. Drop planned .eval new dot command. For shell: Implement undocumented .unknown dot command, doing little. Make dispatcher call .unknown's implementation for unknown dot command. Fix a command lookup bug exposed by above change to unknown handling. Add .eval dot command. Add options to .x command aimed at control of errors in command sequences. (a WIP) Make dispatcher report ambiguous dot command lookups, even with no extension. (check-in: 7616a6f4 user: larrybr tags: cli_extension) | |
| 20:50 | Ensure that sqlite3VdbeMemSetStr() always leaves the value in a consistent state even if there is an error. (check-in: c86ab289 user: drh tags: trunk) | |
| 19:19 | Reverse the order of two tests to stop a harmless initialized value warning from MSAN - reported by OSSFuzz. (check-in: 800b8fda user: drh tags: trunk) | |
| 13:16 | Avoid unnecessary calls to balance() from sqlite3BtreeDelete(). (check-in: d0966d1b user: drh tags: trunk) | |
| 01:43 | Fix the sqlite3_result_xxxxx() routines so that they all check for and perform any necessary text encoding conversions and check for oversize strings and BLOBs. Thus those checks can be done where they are most efficient and avoided in cases like OP_Function where they are more expensive. (check-in: d50b162b user: drh tags: trunk) | |

| 21:42 | TCL extension polished and more smoothly integrated. A couple of bugs related to takedown fixed. Help for added features. Code cleaned up and commented. (check-in: 4ee7df11 user: larrybr tags: cli_extension) | |
| 18:34 | Further size and performance optimizations for sqlite3VdbeMemSetStr(). (check-in: 310a3e10 user: drh tags: trunk) | |
| 17:34 | Slightly smaller and faster sqlite3VdbeMemSetStr(). (check-in: 06928e74 user: drh tags: trunk) | |
| 15:06 | Performance increase in the loop that frees an opcode array. (check-in: 4ccebb86 user: drh tags: trunk) | |
| 14:56 | Another small performance gain by using sqlite3DbFreeNN(). (check-in: daa924af user: drh tags: trunk) | |
| 14:18 | Use sqlite3DbFreeNN() instead of sqlite3DbFree() in a few hot spots for better performance. (check-in: b12de0ec user: drh tags: trunk) | |
| 13:22 | Performance optimization in the memsys5 memory allocator. (check-in: 94913323 user: drh tags: trunk) | |

| 23:33 | TCL extension made to use shell's line inputter with prompting and line editing/history. (check-in: fbf0eb0d user: larrybr tags: cli_extension) | |
| 03:08 | In TCL shell extension, add TCL command "udb". This gets the TCL environment to near parity with pre-extended utility, except for query result display (TBD soon). (check-in: c9aa76bf user: larrybr tags: cli_extension) | |
