| 20:43 | Change the pcache module to keep track of the total number of references to all pages rather than the number of pages references, for a performance improvement and size reduction. (check-in: f00a9e1e99 user: drh tags: trunk) | |
| 18:20 | A simple optimization and size reduction in sqlite3PagerAcquire(). (check-in: 618d8dd4ff user: drh tags: trunk) | |
| 17:54 | Change the Pager.hasBeenUsed flag into Pager.hasHeldSharedLock in order to take it off the critical path in sqlite3PagerAcquire(). (check-in: b79096be7c user: drh tags: trunk) | |
| 13:46 | Add the sqlite3VdbeLoadString() and sqlite3VdbeMultiLoad() routines to help with code generation, especially on PRAGMAs. Rename sqlite3VdbeAddGoto() to just sqlite3VdbeGoto(). (check-in: 847387ec8e user: drh tags: trunk) | |
| 04:28 | Factor out and simplify code in pragma.c for pragmas that return a single row with a single column that is an integer or text value. (check-in: d7f4bdf594 user: drh tags: trunk) | |
| 03:29 | For PRAGMAs, factor out the code that sets the result set column names into a subroutine. (check-in: 0ea6e5c9fc user: drh tags: trunk) | |

| 21:00 | Optimizations to the printf formatter. (check-in: a3b35ddeca user: drh tags: trunk) | |
| 18:40 | Add and use the sqlite3VdbeChangeOpcode() routine. Simplify the implementation of the other sqlite3VdbeChange*() routines. (check-in: 0a5b00e493 user: drh tags: trunk) | |
| 18:19 | Add the sqlite3VdbeAddGoto(v,i) routine as a shorthand for sqlite3VdbeAddOp2(v,OP_Goto,0,i). (check-in: be78f413df user: drh tags: trunk) | |
| 17:55 | Change sqlite3_sql() so that it always returns the SQL text of the prepared statement, if the text is available, even if the the prepared statement was generated using sqlite3_prepare() instead of sqlite3_prepare_v2(). Also include some minor comment fixes and code simplifications. (check-in: 2f5472cfda user: drh tags: trunk) | |
| 16:51 | Small simplification to the EXPLAIN QUERY PLAN logic. (check-in: d1592d201a user: drh tags: trunk) | |

| 14:56 | The sqlite3_memory_alarm() interface has been deprecated and undocumented for almost 8 years (since version 3.5.3). Change it into a no-op. (check-in: 5d3f5df4da user: drh tags: trunk) | |

| 19:41 | Enhance the json_extract() function so that if given multiple PATH arguments it will return a JSON array with all of the answers. Also update comments within the json1 extension to reflect stricter interpretation of JSON and PATH arguments. (check-in: 1da60c3dda user: drh tags: trunk) | |

|

| ||
| 20:07 | Back out the json_check() routine. Instead, throw an error if the input to a json function (other than json_valid()) is not valid JSON. (check-in: dc9ce7b18c user: drh tags: trunk) | |
| 16:41 | Fix compiler warnings in rbu code. (check-in: 0fdc36fe35 user: dan tags: trunk) | |
| 16:18 | When searching the wal file for a frame, do not search that part that was already checkpointed when the transaction was opened. (check-in: a84cf4f5d3 user: dan tags: trunk) | |
| 15:50 | Merge latest trunk into this branch. (Closed-Leaf check-in: ab93024da7 user: dan tags: wal-read-change) | |
| 03:48 | Add the json_check() function, which returns its argument if the argument is well-formed JSON or which throws an error otherwise. (check-in: 64abb65d4d user: drh tags: trunk) | |
| 03:33 | Enhance the json_insert(), json_replace(), and json_set() functions with the ability to add JSON instead of text if the argument is text and if the PATH begins with '$$' instead of just '$'. (check-in: 44f103d886 user: drh tags: trunk) | |
|

| 23:18 | Fix the OR-optimization so that it always ignores subplans that do not use an index. (check-in: 66f92a1686 user: drh tags: trunk) | |
|
2015-08-26

| 21:08 | Reduce the size of the WhereScan object by 24 bytes while also clarifying its operation. (check-in: cbc3c9a8bf user: drh tags: trunk) | |
| 14:01 | Evaluate expressions only once when the same expression is used in both the result set and in the ORDER BY clause. (check-in: c2f3bbad77 user: drh tags: trunk) | |
| 11:40 | Refactor With.a.zErr into With.a.zCteErr. No logic changes. (check-in: 58ba73630e user: drh tags: trunk) | |
| 11:34 | Update the TreeView output for compound SELECT statements so that all entries are shown vertically aligned rather than each successive entry being indented. (check-in: 65a8918776 user: drh tags: trunk) | |

| 20:54 | Remove some redundant code: Call sqlite3ResolveExprListNames() rather than calling sqlite3ResolveExprNames() in a loop - in two places. (check-in: bdaf66465b user: drh tags: trunk) | |
| 20:21 | Enhances the parser so that it accepts arbitrary expressions for the arguments of an index, though the code generator still rejects everything other than simple column names. The sqlite3RestrictColumnListSyntax() routine is removed since that feature is now handled by the parser. (check-in: bed42116ad user: drh tags: trunk) | |
