16:39 | Remove the EXCLUSIVE and CONCURRENT tokens from the tokenizer. Let the BEGIN statement be followed by an ID, but throw a syntax error if the ID is anything other than EXCLUSIVE or CONCURRENT. (check-in: c0bf92eca4 user: drh tags: begin-concurrent) | |
04:31 | Simplification of the LRU list handling in pcache1. (check-in: 05a3a2cd14 user: drh tags: trunk) | |

20:52 | Merge performance enhancements from trunk. This branch now runs (slightly) faster than the 3.8.11.1 release, though still slightly slower than trunk. (check-in: c490bfb150 user: drh tags: begin-concurrent) | |
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) | |
15:17 | Changes from ENABLE_CONCURRENT (default off) to OMIT_CONCURRENT (default on). This is not a clear-cut decision and might be changed back. (check-in: f8ae9bfd05 user: drh tags: begin-concurrent) | |
14:39 | Merge enhancements from trunk. (check-in: 25ee3000e9 user: drh tags: cursor-hints) | |
14:18 | Merge enhancements from trunk. (check-in: 1ab10cbf27 user: drh tags: index-expr) | |
14:04 | Merge trunk optimizations. (check-in: 71e7299e8d user: drh tags: begin-concurrent) | |
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) | |
15:37 | Use sqlite3XPrintf() instead of sqlite3StrAccumAppend() in a few places for better performance and a smaller footprint. (check-in: 82355e4108 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) | |
12:52 | This change is not correct for the boundary case of nCellKey==0. Was: Small performance gain and size reduction in sqlite3VdbeIdxKeyCompare(). (Closed-Leaf check-in: 6e0298cdcb user: drh tags: mistake) | |
2015-09-01
| ||
23:51 | Very minor optimizations in the unix VFS. (check-in: 6db3ff45bc user: drh tags: trunk) | |
22:29 | Performance improvement in sqlite3VarintLen(). (check-in: adf9fefb00 user: drh tags: trunk) | |
20:09 | Small size reduction and performance increase in sqlite3DbMallocSize(). (check-in: 8a80967f84 user: drh tags: trunk) | |
19:51 | Reduce the number of calls to sqlite3BeginBenignMalloc(). (check-in: 0bee658366 user: drh tags: trunk) | |
18:31 | Merge enhancements from trunk. (check-in: 29570a6048 user: drh tags: cursor-hints) | |
18:01 | Merge the latest trunk enhancements. (check-in: 3dea047465 user: drh tags: begin-concurrent) | |
13:17 | Rename SQLITE_FUNC_VARYING to SQLITE_FUNC_SLOCHNG - a more descriptive name for what that bit means. (check-in: ff5137a6dd user: drh tags: index-expr) | |
00:42 | Remove unreachable branches. (check-in: fd4da2318c user: drh tags: index-expr) | |

23:09 | Fix a bug in error reporting when a UNIQUE index on expressions fails its uniqueness test. (check-in: 5a2c0e90a1 user: drh tags: index-expr) | |
21:16 | Not only date/time functions, but also functions like sqlite_version() and changes() need to be prohibited from use inside of indexes. (check-in: 4871313039 user: drh tags: index-expr) | |
19:38 | Always assume that indexed expressions can generate a NULL. Get indexed expressions working for the case of two or more expressions in the same index. (check-in: cc60321a67 user: drh tags: index-expr) | |
18:13 | Case should not be significant when comparing function names. (check-in: e2f1caf117 user: drh tags: index-expr) | |
17:34 | Make the distinction between truly deterministic functions and date/time functions which only return the same answer for a single query. Only truly deterministic functions are allowed in indexes. Add new expression index test cases. (check-in: c77554b5c4 user: drh tags: index-expr) | |
15:58 | Improved analysis and usage of indexed expressions in the query planner. (check-in: f889369638 user: drh tags: index-expr) | |

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) | |
19:03 | Link the json1 extension into the command-line shell by default. (check-in: 2e8e239cec user: drh tags: trunk) | |
