| 20:05 | Modifications to parse.y to better support backwards compatibility for the "window" keyword. (check-in: 7c4b879bdb user: dan tags: weak-fallback) | |
| 03:38 | Introduce the concept of "weak fallback" in the parser. A weak fallback only occurs if a syntax error would result otherwise. (check-in: c41d7079fb user: drh tags: weak-fallback) | |

| 22:25 | • Edit [b959c6297c151150|b959c6297c]: Move to branch partial-index-variables. Edit check-in comment. (artifact: 343898d589 user: drh) | |
| 21:47 | Alternative implementation of exprCompareVariable(). (check-in: b959c6297c user: drh tags: partial-index-variables) | |
| 21:36 | Implement xLock and xTestLock for lsm1 on Win32. (check-in: 9112117dad user: mistachkin tags: lsm-vtab) | |
| 21:35 | • Edit [dbe9c8aa8d70051f|dbe9c8aa8d]: Edit check-in comment. (artifact: 99dd184512 user: mistachkin) | |
| 20:21 | Merge tserver fixes with this branch. (check-in: 58a0aab8fd user: dan tags: server-process-edition) | |
| 20:12 | Fix bugs in test program tserver.c. (Leaf check-in: 093b9108ea user: dan tags: server-edition) | |
| 18:25 | Make the query planners use of partial indexes based on bound variables responsive to the SQLITE_DBCONFIG_ENABLE_QPSG setting. (check-in: a934dd14ac user: drh tags: partial-index-variables) | |
| 18:07 | Merge the in the latest enhancements from trunk. (check-in: 8f63c58632 user: drh tags: partial-index-variables) | |
| 17:29 | Instead of the new sqlite3_prepare_v3() interface, provide the SQLITE_DBCONFIG_PREPARE_FLAGS interface which sets the flags on the single next call to sqlite3_prepare_v2() or its cousins. (Closed-Leaf check-in: 942c3ef8cd user: drh tags: dbconfig-prepare-flags) | |
| 15:56 | Incorporate recent trunk changes. (Closed-Leaf check-in: 62b8269ba2 user: drh tags: prepare_v3) | |
| 15:47 | Build the "stmts" virtual table into the amalgamation. It is active only when compiled using SQLITE_ENABLE_STMTSVTAB. That option is supplied to the command-line shell. (check-in: 0ff057d86e user: drh tags: stmts-vtab) | |
| 15:17 | Fix harmless compiler warnings in the CSV extension. (check-in: f02a54599d user: drh tags: trunk) | |
| 15:01 | Faster parser stack overflow detection. (check-in: 36e54cd8b1 user: drh tags: trunk) | |
| 14:26 | Minor tweak to the SQL grammar to make the parser tables a few bytes smaller. (check-in: cc4810b23e user: drh tags: trunk) | |
| 13:47 | In the lemon-generated parser, store the number of symbols on the RHS of each rule as a negative number and add it to the stack pointer, rather than storing the value as a positive and subtracting it. This makes the parser faster. (check-in: b362f0d8ed user: drh tags: trunk) | |
| 11:56 | In the lemon-generated parser, automatically promote SHIFTREDUCE actions on nonterminal systems to pure REDUCE actions, for a performance enhancement. (check-in: c46d94a8cd user: drh tags: trunk) | |
| 01:21 | Simplify error handling logic in sqlite3_exec() to save about 40 bytes. (check-in: 6480916c72 user: drh tags: trunk) | |
| 01:12 | Minor code simplification in the ALTER TABLE logic. (check-in: bfc4e7f30e user: drh tags: trunk) | |
| 00:55 | Avoid an unnecessary call to sqlite3XPrintf() in the code generator, for a performance improvement. (check-in: 29d6ceb383 user: drh tags: trunk) | |

| 17:33 | Comment typo fix and minor cleanup in the pager. No logic changes. (check-in: 94ef170128 user: drh tags: trunk) | |
| 02:58 | Avoid unnecessary calls to sqlite3VdbeSerialTypeLen() for integer serial types, for a small size reduction and a speed increase. (check-in: 9cd30d33b1 user: drh tags: trunk) | |

| 19:04 | Add extra pager tests. (check-in: 6b7e419ddc user: dan tags: trunk) | |
| 11:23 | Fix some errors when compiling with SQLITE_OMIT_WAL. (check-in: 3b68cb9c65 user: dan tags: trunk) | |
| 11:06 | Remove debugging code from test script. (check-in: a85ae33246 user: dan tags: trunk) | |
| 10:15 | Currently, if SQLite cannot find a table or index referred to by a query, it reloads the database schema from disk to see if the table or index has been added since the schema was cached in memory. Extend this behaviour to columns (which may have been added using ALTER TABLE) and fix some obscure cases related to tables and indexes (INDEXED BY, DROP TABLE etc.).
