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: c322bfa27e user: drh tags: trunk) | |
12:54 | Implement xUnlink, xShmMap, and xShmUnmap for lsm1 on Win32. (Closed-Leaf check-in: 680cc064c9 user: mistachkin tags: lsm-vtab) | |

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) | |

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.

17:30 | Add the SQLITE_STMTSTATUS_MEMUSED opcode to sqlite3_stmt_status() for finding the heap memory usage by a single prepared statement. (check-in: c26cf978ee user: drh tags: trunk) | |
16:21 | Add the SQLITE_STMTSTATUS_MEMUSED option for sqlite3_stmt_status() that reports the amount of heap memory used for a single prepared statement. (Closed-Leaf check-in: b57d510465 user: drh tags: stmtstatus-memused) | |
16:09 | Add the experimental "stmts" virtual table for introspection of prepared statements. (check-in: cb4c5c66ab user: drh tags: trunk) | |
13:45 | Avoid allocating excess memory to the KeyInfo objects. (check-in: df78594351 user: drh tags: trunk) | |
13:27 | Remove a completely unnecessary memset() from the INSERT code generator. (check-in: 7d58836b9d user: drh tags: trunk) | |
11:24 | Very small performance increase in sqlite3VdbeSetNumCols(). (check-in: 8885b44610 user: drh tags: trunk) | |
03:20 | Reorder fields in the PgHdr object for a performance increase. (check-in: 326e63d71e user: drh tags: trunk) | |
02:58 | Avoid unnecessary memory zeroing during expression list allocation. (check-in: de28e6514a user: drh tags: trunk) | |
00:49 | Size and performance optimizations to sqlite3ResolveExprNames(). (check-in: af8c0fed93 user: drh tags: trunk) | |
2017-05-30

18:34 | Change sqlite3BtreeNext() and sqlite3BtreePrevious() so that they return SQLITE_DONE if they have already reached the end (or beginning) of the table. This gives a performance increase and size reduction. (check-in: e972a38608 user: drh tags: trunk) | |
18:14 | Omit a test of codepoint 0x202F (non-break narrow space) from the fts3 ICU tests. Different versions of ICU apparently handle this obscure codepoint slightly differently. (check-in: 69ae688982 user: dan tags: trunk) | |

22:44 | More efficient error handling and reset in the binding mechanism. (check-in: 9a3e3b34ba user: drh tags: trunk) | |
17:59 | Omit unnecessary fstat() calls for determining the database file size, resulting in smaller and faster code. (check-in: dd61c73677 user: drh tags: trunk) | |

14:26 | Optimizations to the Walker object and its methods to make the code a little smaller and to help it run a little faster. (check-in: 6854a34ed7 user: drh tags: trunk) | |
13:09 | Correctly initialize the iSelectId of FROM clause terms that are a self join of a reused materialized subquery. Without this, the EXPLAIN QUERY PLAN output for the query will identify the subquery using the uninitialized (and arbitrary) iSelectId. (check-in: 43c9ae371f user: drh tags: trunk) | |
03:48 | Improve shell help text for the '.open' command. (check-in: 7cc940a97e user: mistachkin tags: trunk) | |

17:27 | Merge the LEFT JOIN query flattener fixes from 3.19.2. (check-in: 6513e4a121 user: drh tags: trunk) | |
16:50 | Version 3.19.2 (check-in: edb4e819b0 user: drh tags: release, version-3.19.2, branch-3.19) | |
11:39 | The SQLITE_EXTRA_IFNULLROW compile-time option causes OP_IfNullRow opcodes to be issued for references to the right-hand side table of *any* flattened join, not just LEFT JOINs. This puts extra stress on the OP_IfNUllRow opcodes for testing purposes. (check-in: 1a074c8a2b user: drh tags: branch-3.19) | |
00:28 | The TK_IF_NULL_ROW expression node must be treated as a variable that references the table Expr.iTable. Proposed fix for ticket [7fde638e94287d2c]. (check-in: b30a364a12 user: drh tags: branch-3.19) | |
00:12 | Increase the version number to 3.19.2 since ticket [7fde638e94287d2] is going to necessitate another patch release. (check-in: c315727acd user: drh tags: branch-3.19) | |

20:00 | Remove the msvc.h header file from the autoconf tarball. (check-in: 84996aef68 user: drh tags: trunk) | |
19:35 | Do not use strcpy() in the (obsolete) amatch extension. In releasetest.tcl, run Apple tests using -Os instead of -O1 (check-in: 4440e42031 user: drh tags: trunk) | |
15:33 | Disable the LEFT JOIN flattening optimization for aggregate queries, as it does not currently work. Further fix for ticket [cad1ab4cb7b0fc344]. (check-in: 05ada74155 user: drh tags: branch-3.19) | |

12:44 | Ensure that the expression rewriter inside the query flattener decends into the substructure of the TK_IF_NULL_ROW operator. This is a continuation of the fix for ticket [cad1ab4cb7b0fc344]. (check-in: 28d2902d8f user: drh tags: branch-3.19) | |

01:35 | Change the version number to 3.19.1. (check-in: 16656b8ff5 user: drh tags: branch-3.19) | |
01:30 | Remove a surplus semicolon, which was harmless on gcc and clang but caused compile-time errors on msvc. This only comes up using the encryption extension. (check-in: 4510d55d1e user: drh tags: branch-3.19) | |
01:29 | When flattening a query, make sure iTable attribute of TK_IF_NULL_ROW operators (that result from a prior flattening of a LEFT JOIN) are updated correctly. Fix for ticket [cad1ab4cb7b0fc344]. (check-in: 919d36e6ea user: drh tags: branch-3.19) | |

18:09 | Fix incompatibilities between the "sqldiff --changeset" command and the sessions module. Specifically, allow sessions to process changesets containing tables with zero operations on them and have sqldiff output the expected output for tables with multi-column primary keys. (check-in: 0bb23c4806 user: dan tags: trunk) | |
18:00 | Add the ".cd" command to the command-line shell. (check-in: 5fe28e15b1 user: drh tags: trunk) | |

13:06 | Include the "msvc.h" header file in the amalgamation tarball. (check-in: 3dd6fe53c7 user: drh tags: branch-3.19) | |
08:04 | Fix a case where NULL was being passed to memcmp() following an OOM. This is probably not a real problem, as the number-of-bytes parameter was passed 0 in this case, but it was causing a santizer complaint. (check-in: 3ea2bad27e user: dan tags: trunk) | |
