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: c0bf92ec user: drh tags: begin-concurrent
04:31
Simplification of the LRU list handling in pcache1. check-in: 05a3a2cd user: drh tags: trunk
2015-09-03
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: c490bfb1 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: f00a9e1e user: drh tags: trunk
18:20
A simple optimization and size reduction in sqlite3PagerAcquire(). check-in: 618d8dd4 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: b79096be 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: f8ae9bfd user: drh tags: begin-concurrent
14:39
Merge enhancements from trunk. check-in: 25ee3000 user: drh tags: cursor-hints

Merge enhancements from trunk. check-in: 1ab10cbf user: drh tags: index-expr
14:04
Merge trunk optimizations. check-in: 71e7299e 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: 847387ec 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: d7f4bdf5 user: drh tags: trunk
03:29
For PRAGMAs, factor out the code that sets the result set column names into a subroutine. check-in: 0ea6e5c9 user: drh tags: trunk
2015-09-02
21:00
Optimizations to the printf formatter. check-in: a3b35dde user: drh tags: trunk
18:40
Add and use the sqlite3VdbeChangeOpcode() routine. Simplify the implementation of the other sqlite3VdbeChange*() routines. check-in: 0a5b00e4 user: drh tags: trunk
18:19
Add the sqlite3VdbeAddGoto(v,i) routine as a shorthand for sqlite3VdbeAddOp2(v,OP_Goto,0,i). check-in: be78f413 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: 2f5472cf user: drh tags: trunk
16:51
Small simplification to the EXPLAIN QUERY PLAN logic. check-in: d1592d20 user: drh tags: trunk
15:37
Use sqlite3XPrintf() instead of sqlite3StrAccumAppend() in a few places for better performance and a smaller footprint. check-in: 82355e41 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: 5d3f5df4 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: 6e0298cd user: drh tags: mistake
2015-09-01
23:51
Very minor optimizations in the unix VFS. check-in: 6db3ff45 user: drh tags: trunk
22:29
Performance improvement in sqlite3VarintLen(). check-in: adf9fefb user: drh tags: trunk
20:09
Small size reduction and performance increase in sqlite3DbMallocSize(). check-in: 8a80967f user: drh tags: trunk
19:51
Reduce the number of calls to sqlite3BeginBenignMalloc(). check-in: 0bee6583 user: drh tags: trunk
18:31
Merge enhancements from trunk. check-in: 29570a60 user: drh tags: cursor-hints
18:01
Merge the latest trunk enhancements. check-in: 3dea0474 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: ff5137a6 user: drh tags: index-expr
00:42
Remove unreachable branches. check-in: fd4da231 user: drh tags: index-expr
2015-08-31
23:09
Fix a bug in error reporting when a UNIQUE index on expressions fails its uniqueness test. check-in: 5a2c0e90 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: 48713130 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: cc60321a user: drh tags: index-expr
18:13
Case should not be significant when comparing function names. check-in: e2f1caf1 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: c77554b5 user: drh tags: index-expr
15:58
Improved analysis and usage of indexed expressions in the query planner. check-in: f8893696 user: drh tags: index-expr
