| 20:11 | Improved documentation for sqlite3_value_type(). check-in: 0db20efe user: drh tags: trunk | |
| 19:22 | Add some assert() statements in the Win32 interface for lsm1. check-in: d076d58f user: mistachkin tags: trunk | |
| 18:12 | Fix some minor typos in lsm1. check-in: 0ef777d7 user: mistachkin tags: trunk | |
| 11:44 | Avoid constantly freeing and reallocing small internal buffers associated with LSM cursors. Instead, allow them to persist for the lifetime of the cursor if they are LSM_SEGMENTPTR_FREE_THRESHOLD (default 1024) bytes or smaller. This change is based on research by Martijn Blaauw. check-in: bacfe8cb user: dan tags: trunk | |

| 21:33 | In the command-line shell, add the -quote option to start up in quote mode. Enhance the ".mode" command so that it reports the current output mode if given no arguments. check-in: 5e3f9ea5 user: drh tags: trunk | |
| 21:11 | Remove the ".explain" command from the ".help" output of the command-line shell, though keep the implementation around for backwards compatibility. check-in: 7782c04e user: drh tags: trunk | |
| 20:31 | Some simple tests for the STMT virtual table. check-in: a26e17ee user: drh tags: trunk | |
| 20:23 | Avoid reading or writing the 32 locking bytes at the end of the first meta-page of an LSM database. check-in: 3ed6877f user: dan tags: trunk | |

| 19:08 | Fix issues in the POSIX and Win32 interfaces for lsm1. check-in: 38ec4141 user: mistachkin tags: trunk | |
| 17:27 | Edit comments in sqlite.h.in used for generating documentation, to improve the description of the new sqlite3_prepare_v3() interfaces, and other miscellaneous cleanup. No changes to executable code. check-in: 284707a7 user: drh tags: trunk | |
| 16:51 | More updates to the Win32 interface for lsm1. check-in: cae64769 user: mistachkin tags: trunk | |
| 15:57 | Correct typo in the Win32 interface for lsm1. check-in: 1b4facb1 user: mistachkin tags: trunk | |
| 15:24 | Add interfaces sqlite3_prepare_v3() and sqlite3_prepare16_v3() with the extra prepFlags argument. Add the SQLITE_PREPARE_PERSISTENT option as one bit in that argument. Use the new option in FTS3, FTS5, and RTREE. check-in: 03977248 user: drh tags: trunk | |
| 15:13 | Further corrections to the Win32 interface for lsm1. check-in: 4df6e247 user: mistachkin tags: trunk | |
| 14:33 | Rename the "stmts" virtual table to just "stmt" without the final "s". check-in: adfdb801 user: drh tags: trunk | |
| 14:17 | A couple fixes for the Win32 interface for lsm1. check-in: ebbd98e9 user: mistachkin tags: trunk | |

| 13:13 | Add the "stmts" virtual table to the amalgamation, activated when compiled using -DSQLITE_ENABLE_STMTSVTAB. Add the SQLITE_STMTSTATUS_REPREPARE and SQLITE_STMTSTATUS_RUN statistics outputs from sqlite3_stmt_status() and add corresponding columns to the stmts virtual table. Change the numeric value of SQLITE_STMTSTATUS_MEMUSED to get it out of the way of counter values. check-in: 88976ae3 user: drh tags: trunk | |
| 12:59 | The query planner examines the values of bound parameters to help determine if a partial index is usable. Reprepares may happen if the bindings change. This behavior is disabled by the QPSG setting. check-in: c322bfa2 user: drh tags: trunk | |
| 12:54 | Implement xUnlink, xShmMap, and xShmUnmap for lsm1 on Win32. Closed-Leaf check-in: 680cc064 user: mistachkin tags: lsm-vtab | |
| 12:49 | Add the SQLITE_STMTSTATUS_REPREPARE and SQLITE_STMTSTATUS_RUN options to sqlite3_stmt_status(). Use this for two new columns in the stmts virtual table. Closed-Leaf check-in: b0b0c8f8 user: drh tags: stmts-vtab | |

| 21:47 | Alternative implementation of exprCompareVariable(). check-in: b959c629 user: drh tags: partial-index-variables | |
| 21:36 | Implement xLock and xTestLock for lsm1 on Win32. check-in: 9112117d user: mistachkin tags: lsm-vtab | |
| 18:25 | Make the query planners use of partial indexes based on bound variables responsive to the SQLITE_DBCONFIG_ENABLE_QPSG setting. check-in: a934dd14 user: drh tags: partial-index-variables | |
| 18:07 | Merge the in the latest enhancements from trunk. check-in: 8f63c586 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: 942c3ef8 user: drh tags: dbconfig-prepare-flags | |
| 15:56 | Incorporate recent trunk changes. Closed-Leaf check-in: 62b8269b 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: 0ff057d8 user: drh tags: stmts-vtab | |
| 15:17 | Fix harmless compiler warnings in the CSV extension. check-in: f02a5459 user: drh tags: trunk | |
| 15:01 | Faster parser stack overflow detection. check-in: 36e54cd8 user: drh tags: trunk | |
| 14:26 | Minor tweak to the SQL grammar to make the parser tables a few bytes smaller. check-in: cc4810b2 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: b362f0d8 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: c46d94a8 user: drh tags: trunk | |
| 01:21 | Simplify error handling logic in sqlite3_exec() to save about 40 bytes. check-in: 6480916c user: drh tags: trunk | |
| 01:12 | Minor code simplification in the ALTER TABLE logic. check-in: bfc4e7f3 user: drh tags: trunk | |

| 16:48 | Merge latest trunk changes with this branch. check-in: 2b095406 user: dan tags: apple-osx | |
| 16:39 | Fix a virtual table problem that can occur when the vtab is on the RHS of a LEFT JOIN and there is a MATCH constraint in the ON clause, or when the vtab is in a sub-query that is the RHS of a LEFT JOIN and there is a MATCH constraint in the WHERE clause of the sub-query. check-in: 87b38166 user: dan tags: trunk | |

| 13:57 | Add the SQLITE_DBCONFIG_ENABLE_QPSG option to activate the query planner stability guarantee. This involves refactoring the sqlite3.flags bitvector to carve out a free bit to use. check-in: 7076e828 user: drh tags: enable-QPSG | |
| 11:46 | Remove an invalid assert() from lsm test code. check-in: ca8a7e99 user: dan tags: lsm-vtab | |

| 19:06 | Avoid adding an artifical "LIMIT 1" on scalar subqueries that do not need it. This seems like a pointless optimization as it makes minimal run-time difference but does increase code complexity. Parked on a branch for historical reference. Leaf check-in: c21628e9 user: drh tags: subquery-limit-opt | |

This gives better query plans for tables that are truely empty, but is likely to cause problems in legacy systems, so the change is kept off trunk.
