Following month ↑
2022-03-31
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)
2022-03-30
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)
2022-03-29
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

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)
2022-03-28
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)

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)
2022-03-26

Fix the code generated for vector IN operator constraints on virtual tables so that they work even if the "omit" field in the sqlite3_index_info object is off. This has apparently never worked correctly before. Presumably, nobody has ever before written a virtual table that can use vector IN operator constraints and that relies on bytecode to double-check the constraints. Test cases in TH3. Problem discovered by dbsqlfuzz cab8e26194a40147627094f3c6849c0a7b1e0310. (check-in: 4a2040d5 user: drh tags: branch-3.38)

Optimizations to sqlite3BtreeIndexMoveto() avoid unnecessary comparisons if the cursor is already near the end of the table and is not moving far. This case is more common that you would expect. The optimization saves almost 4 million CPU cycles. (check-in: 0057bbb5 user: drh tags: trunk)

Fix for the problem identified in forum post 0cd8e058bf: When evaluating an multi-index OR, do not push down auxiliary WHERE clause terms that involve subqueries into the OR-subqueries. Otherwise, the covering-index optimizer might convert table-references into index-references for the particular OR index that is active for the branch in which the subquery subroutine is coded, and those index-references will not work if the subquery subroutine is invoked from a different OR branch that uses a different index.

The MemPage.aDataEnd field should point to the end of the data buffer for the page, not just the end of the usable portion of that buffer. The purpose aDataEnd is to detect cells that overflow the page, and that won't work on a page with reserved bytes and a cell that starts in the reserved region, unless the boundary is at the very end of the page.
