| 23:39 | Very small optimization in the bytecode engine. (check-in: 46002511e5 user: drh tags: trunk) | |
| 11:00 | Fix a segfault introduced by the row-value enhancement that comes up on a skip-scan where the first term of the index is unconstrained and the second term is of the form "columm IN (SELECT...)". (check-in: 2401ea5acf user: drh tags: trunk) | |
| 10:24 | Improved performance in sqlite3ExprCodeTarget(). (check-in: 75146165dc user: drh tags: trunk) | |
| 02:19 | Small performance optimization in the expression walker. (check-in: c6e6afb939 user: drh tags: trunk) | |

| 20:27 | Do not allow table-valued function syntax to be used on a view. (check-in: 97cfe346e1 user: drh tags: trunk) | |
| 19:36 | Add the --disable-lookaside option to the fuzzershell utility program. (check-in: 0b04374449 user: drh tags: trunk) | |
| 18:54 | Fix a memory leak in json1.c that could occur after misuse of json_object(). (check-in: 394b81b11f user: drh tags: trunk) | |
| 18:11 | Add an assert() statement to delete.c. (check-in: 40fce67ecf user: dan tags: trunk) | |
| 18:08 | Fix compiler warnings. (check-in: 5c31ee62a1 user: drh tags: trunk) | |
| 16:51 | Add json1.c to the fuzzer test shells. (check-in: 809d67b611 user: drh tags: trunk) | |
| 16:45 | Adjust Makefiles to use SQLITE_CORE when statically linking json1.c into test shells. (Closed-Leaf check-in: 91682ac39e user: drh tags: json-fuzz) | |
| 16:24 | • Edit [c4b68eff7f8f5402|c4b68eff7f]: Move to branch json-fuzz. (artifact: 048cdbb53c user: drh) | |
| 14:57 | Adjust fuzzershell so that it adds the json1 extension separately for each no connection. (check-in: ca2d1e9036 user: drh tags: json-fuzz) | |
| 14:32 | Include json1.c in fuzzcheck and fuzzershell. (check-in: c4b68eff7f user: drh tags: json-fuzz) | |
| 12:04 | Fix a documentation typo in sqlite3_bind_parameter_index(). No code changes. (check-in: 650605a820 user: drh tags: trunk) | |
| 11:57 | Fix an off-by-one error (really off-by-2 in this case) in the buffer resize logic of json1. (check-in: d2a027372a user: drh tags: trunk) | |
| 03:07 | Do not allow rowid in a UNIQUE or PRIMARY KEY constraint. (This restores the same behavior exhibited by all prior releases.) (check-in: b1278301e3 user: drh tags: trunk) | |

| 22:44 | Simplify two conditionals and add testcase() macros to the affinity transform logic in the comparison operators. (check-in: 544664cadf user: drh tags: trunk) | |
| 22:30 | Recognize the invariant that a Mem object cannot be MEM_Dyn and have a non-zero szMalloc at the same time. Enforce this with assert()s and exploit it in the sqlite3VdbeMemClearAndResize() routine for a performance increase. (check-in: 3b21cf2b28 user: drh tags: trunk) | |
| 22:01 | Tighten the conditions under which applyNumericAffinity() be called and add assert() statements to prove that it is never called otherwise. (check-in: e996ca32cb user: drh tags: trunk) | |
| 20:13 | Fix the affinity on inserts into the ANALYZE tables. Change the affinity characters to be upper case, to make the P5 parameter of comparison operators easier to read. (check-in: 3f3ca76aea user: drh tags: trunk) | |
| 19:43 | Do not attempt to extend the temp file if VFS version 3 is not supported and hence memory mapped I/O is unavailable. (check-in: 3ab20ba14f user: drh tags: trunk) | |
| 19:00 | Make the "nolock" VFS on unix a version-3 VFS so that the sorter can use memory-mapped I/O. (check-in: 3db78d6100 user: drh tags: trunk) | |
| 18:08 | Add further tests to ota5.test. Add "ota.test", for running all ota tests. (check-in: 95ffdaa542 user: dan tags: ota-update) | |
| 16:56 | Remove a local variable from the OP_Column implementation, resulting in a modest size reduction and a performance increase. (check-in: 6199760d13 user: drh tags: trunk) | |
| 16:13 | Small size reduction and performance increase for releaseMemArray(). (check-in: 24cd32d681 user: drh tags: trunk) | |
| 16:02 | Updates to comments. No code changes. (check-in: 9b42c3da6b user: drh tags: trunk) | |
| 15:28 | The OP_Column opcode runs faster and is smaller by manually in-lining the code that persists string values in the output register. (check-in: 36b613ccf0 user: drh tags: trunk) | |
| 15:06 | Add extra tests for the ota extension. (check-in: 1e468fe1e4 user: dan tags: ota-update) | |
| 04:42 | Add the sqlite3VdbeMemClearAndResize() function. Fix a sorting-index prefilter problem. (check-in: 987a7a2119 user: drh tags: trunk) | |
| 04:36 | • Edit [5b9b8987797abf7c|5b9b898779]: Move to branch Cplusplus-comment. Edit check-in comment. (artifact: 7dfa0d57fd user: drh) | |
| 02:01 | Make sure that the sorting-index pre-filter recognizes that a rowid reference might be sortable. This fixes a performance regression. (Closed-Leaf check-in: 72727b68cd user: drh tags: Cplusplus-comment) | |
| 00:43 | Add the sqlite3VdbeMemClearAndResize() interface to be used in place of sqlite3VdbeMemGrow(). A C++ style comment was left in this check-in by mistake, and so it has been moved into a branch to avoid problems in any future bisects on windows. (check-in: 5b9b898779 user: drh tags: Cplusplus-comment) | |

| 18:32 | Speed up releaseMemArray() a bit by handling the most common types of memory cells inline. (CVS 5726) (check-in: ce07508550 user: danielk1977 tags: trunk) | |
| 16:39 | In function moveToRoot(), use the MemPage.pParent pointers to find the root page if they are valid. This is slightly faster than requesting a new reference to the root page from the pager layer. (CVS 5725) (check-in: 0c8b74e668 user: danielk1977 tags: trunk) | |
| 15:10 | In sqlite3BtreeGetMeta(), if BtShared.pPage1 is available use it instead of requesting a new reference from the pager layer. (CVS 5724) (check-in: 59be34cfa4 user: danielk1977 tags: trunk) | |
| 09:14 | Remove an obsolete layer of redirection in pager.c. (CVS 5723) (check-in: 75deaa442f user: danielk1977 tags: trunk) | |
