| 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) | |

| 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) | |

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) | |

| 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) | |

| 22:33 | Improve a local variable name. (check-in: d0f6973d user: mistachkin tags: lsm-vtab) | |
| 22:27 | Initial work on porting lsmtest to Win32. (check-in: 7e669d9b user: mistachkin tags: lsm-vtab) | |

| 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) | |

| 16:13 | Add the "-unsetnull 1" option to the "sqlite3" command in the TCL interface. (Closed-Leaf check-in: cbe441b2 user: drh tags: unsetnull-option) | |
| 14:46 | Make sure sqlite3VdbeSetVarmask() is never invoked when QPSG is enabled. (Closed-Leaf check-in: ebcfa73e user: drh tags: enable-QPSG) | |
| 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) | |
| 18:49 | Fix a missing comma in the previous check-in. (check-in: f3db02f4 user: drh tags: trunk) | |
| 17:55 | Rework the code in ctime.c a bit to report on more compile time options. And to only output configuration options passed in to SQLite, not the default values of #define symbols set automatically. Also generate the large array in ctime.c using new script tool/mkctime.tcl, instead of entering it manually. (check-in: 9a443397 user: dan tags: trunk) | |

| 10:55 | Cause the ANALYZE command to build sqlite_stat1 table entries for empty tables with the assumption that such tables really contain 10 elements. 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.
