| 23:25 | More tweaks to improve the performance of the insert logic, slightly. (check-in: dec13075 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: 55f348cd user: drh tags: trunk) | |
| 19:10 | Remove some unused legacy code from the btree insert logic. (check-in: 2ce11667 user: drh tags: trunk) | |
| 18:50 | Use pthreads mutexes and conditions to synchronize threads in bc_test1. (check-in: f33aa76f user: dan tags: begin-concurrent) | |
| 12:29 | Yet another minor size reduction and performance increase in the b-tree insert logic. (check-in: 1dbaf7a1 user: drh tags: trunk) | |
| 11:23 | Small size reduction and performance increase in the sqlite3BtreeInsert() logic. (check-in: 656aa1ec 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: b9e45596 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: b3bb660a 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: 31b13eb5 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: 000197cc 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: 9e3f64a4 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: 09784f37 user: drh tags: branch-3.7.11) | |
| 01:04 | Do not allow virtual table constructors to be called recursively. Cherrypick [0a72726da21581ab] (check-in: 0f0694e4 user: drh tags: branch-3.7.11) | |
| 00:50 | Add the ".open" command to the command-line shell. Cherrypick from [21eccb919441]. (check-in: a71e2a72 user: drh tags: branch-3.7.11) | |
