| 23:25 | More tweaks to improve the performance of the insert logic, slightly. (check-in: dec1307581 user: drh tags: trunk) | |
| 20:03 | Simplify the sqlite3BtreeInsert() interface by gathering the five arguments describing the content to be inserted into the new BtreePayload structure, and thus reducing the number of parameters from eight to four. (check-in: 55f348cdd2 user: drh tags: trunk) | |
| 19:10 | Remove some unused legacy code from the btree insert logic. (check-in: 2ce1166717 user: drh tags: trunk) | |
| 18:50 | Use pthreads mutexes and conditions to synchronize threads in bc_test1. (check-in: f33aa76f07 user: dan tags: begin-concurrent) | |
| 12:29 | Yet another minor size reduction and performance increase in the b-tree insert logic. (check-in: 1dbaf7a119 user: drh tags: trunk) | |
| 11:23 | Small size reduction and performance increase in the sqlite3BtreeInsert() logic. (check-in: 656aa1ecf5 user: drh tags: trunk) | |
| 00:45 | Add the shell-script used for routine performance testing. (check-in: 8e366f18f5 user: drh tags: trunk) | |

| 20:26 | Have r-tree prefer to use the constraint "col MATCH ?" over "rowid = ?". drh added later: All changes on this branch have been cherrypicked to trunk and will be merged into sessions from trunk. So this branch can close. (Closed-Leaf check-in: b9e45596d8 user: dan tags: sessions-value-dup) | |
| 17:24 | Prevent a virtual table from being destroyed while it is in use. Also: replace Vdbe.inVtabMethod with sqlite3.nVDestroy. Simplify the EXPLAIN output for P4.pVtab to only show the sqlite3_vtab pointer. Cherrypick of [cbeb9a1aed8c]. (check-in: b3bb660af9 user: dan tags: branch-3.8.6) | |
| 17:21 | Avoid ever writing before the start of an allocated buffer in the DIRECT_OVERFLOW_READ code. Fix for [e3a290961a6]. Cherrypick of [c3c15d20c691]. (check-in: 31b13eb528 user: dan tags: branch-3.8.6) | |
| 02:24 | Silently ignore any attempt to add a prefix index for prefixes zero bytes in size to an fts3/4 table. Or any prefix index size so large that it overflows a 32-bit signed integer. Cherrypick [ad4b19d2ac0889a] (check-in: 000197cc4e user: drh tags: branch-3.7.11) | |
| 02:20 | Ensure that tables names are dequoted exactly once by the trigger logic. Cherrypick [59e92bd9521f1e8] and [9d887b92f8086961e]. (check-in: 9e3f64a4f4 user: drh tags: branch-3.7.11) | |
| 02:07 | When parsing the schema, ignore any SQL that does not begin with "CREATE". Cherrypick of [d3c00d61581c] with additional changes. (check-in: 09784f376b user: drh tags: branch-3.7.11) | |
| 01:04 | Do not allow virtual table constructors to be called recursively. Cherrypick [0a72726da21581ab] (check-in: 0f0694e424 user: drh tags: branch-3.7.11) | |
| 00:50 | Add the ".open" command to the command-line shell. Cherrypick from [21eccb919441]. (check-in: a71e2a72c5 user: drh tags: branch-3.7.11) | |

| 08:48 | Do not burn memory remembering CHECK constraints in a read-only database. (check-in: 34ddf02d3d user: drh tags: trunk) | |
| 08:21 | Fix the sqlite3_db_readonly() API so that it reports true if the database is readonly because the file format write version (byte 18 of the header) is too large. (check-in: 8d8af114da user: drh tags: trunk) | |

| 20:41 | Simplifications to expr.c in support of full coverage testing. (CVS 6665) (check-in: 309adb5e22 user: drh tags: trunk) | |
| 15:15 | In the CLI in the ".dump" command, do not attempt to clear the sqlite_sequence table until the first row of content of that table is seen. Ticket #3867 (CVS 6664) (check-in: bedd5ad194 user: drh tags: trunk) | |
| 14:51 | In the CLI, always "dump" the sqlite_sequence table last. Ticket #3867 (CVS 6663) (check-in: a0028d4808 user: drh tags: trunk) | |
| 04:42 | Add conditional 'extern "C"' block to sqlite3async.h. Ticket #3866. (CVS 6662) (check-in: e4d1b117c9 user: danielk1977 tags: trunk) | |

| 03:01 | Eliminate the OP_SortMakeRec and OP_SortCallback opcodes. Sort using the standard record format. (CVS 1426) (check-in: 25643a0137 user: drh tags: trunk) | |
| 02:14 | Most sorting problems are fixed. Dead code has been removed. 3 test failures remain but will be fixed by the new function API once it gets implemented. (CVS 1425) (check-in: 3b55095e03 user: drh tags: trunk) | |
