Avoid constantly freeing and reallocing small internal buffers associated with LSM cursors.

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)

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)

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)
06:28
Minor corrections to the previous check-in. (check-in: e1cf8a78 user: mistachkin tags: lsm-vtab)

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)
17:29
Ensure that the value of the THREADSAFE symbol is always included when reporting compile time options, even if it was not explicitly configured. (Closed-Leaf check-in: 95141c64 user: dan tags: ctime-refactor)
