[7556bd9aa5] Update requirements marks. No changes to code. (user: drh, tags: trunk)
17:49
[bdaa694737] Improvements to the way the query planner handles sorting costs, so that very large sorting costs do not overwhelm the loop costs. (user: drh, tags: trunk)
17:25
[43c59c8543] Closed-Leaf: Fix a buffer overrun in the previous commit. (user: dan, tags: query-planner-fix)
16:52
[299b957027] Because SQLite internally calculates query plan costs using a logarithmic scale, very large estimated sorting costs can cause all other estimated costs to be rounded down to zero. In these cases break ties between plans with the same total cost by comparing the costs with sorting excluded. This is an alternative fix for the problem addressed by 2af630c572. (user: dan, tags: query-planner-fix)
15:38
[36b7c5cefc] The SQLITE_IOERR_BLOCKED extended error code is not longer used, so remove assert() statements and documentation for that error code. Also make other documentation improvements. (user: drh, tags: trunk)

2014-08-07
20:42
[2af630c572] When the estimated sorting cost overwhelms the estimated lookup cost, ensure that lookup costs are still taken into account when selecting a lookup algorithm. (user: drh, tags: trunk)
20:37

16:50
[ec5d84ba69] Oops! This check-in was on trunk. But it contains a debugging printf(). Original comment: When the estimated cost to do a sort overwhelms the estimated cost to do individual table lookups, make sure that the table lookup costs are still taken into consideration when selecting the lookup algorithm. (user: drh, tags: query-planner-fix)
2014-08-06
18:50
[bcf6d775f9] A couple more harmless compiler warnings eliminated. (user: drh, tags: trunk)
17:49

14:36
[1202e9771f] Fix harmless compiler warnings. In the command-line shell, report if the ".system" command returns a non-zero result. (user: drh, tags: trunk)
12:00
[69018967f6] Merge the second InterlockedCompareExchange() fix from trunk. (user: drh, tags: sessions)
11:58
[5c6bb57d90] Fix an obsolete comment in the func.c source file. No changes to code. (user: drh, tags: trunk)
11:57
[ab1a751e13] On the windows VFS, do not try to make InterlockedCompareExchange an overloadable function, since sometimes it is a macro. (user: drh, tags: trunk)
03:16
[091aa5f104] Merge in the fix for the InterlockedCompareExchange() build issue. (user: drh, tags: sessions)
03:06

01:08
[717245d487] Fix typos in the opcode documentation. Comment changes only. No changes to code. (user: drh, tags: trunk)
00:29
[0ad1ed8ef0] A simpler fix for ticket [3a88d85f36704eebe1] - one that uses less code. The error message is not quite as good, but as this error has apparently not previously occurred in over 8 years of heavy use, that is not seen as a serious problem. (user: drh, tags: trunk)
2014-08-05
21:31
[29ba812825] Ensure that aggregate functions are not used when evaluating a default value for a table column. Candidate fix for ticket [3a88d85f36704eebe134f7]. (user: drh, tags: trunk)
19:16
[952868216854e] Add the ability to evaluate IN operators as a sequence of comparisons as an alternative to the long-standing algorithm of building a lookup table.

11:04

2014-08-04
15:12
[2f724cbac9] Closed-Leaf: Changed my mind: This opcode name changes mere creates unnecessary diff marks between older and newer versions without significantly improving readability. Was: Rename the IsNull opcode to IfNull and rename the NotNull opcode to IfNotNull. (user: drh, tags: deadend)
2014-08-02
21:03
[436e884215] Enhancements to the code generator for the IN operator that result in much faster queries in some cases, for example when the RHS of the IN operator changes for each row of a large table scan. (user: drh, tags: IN-operator-improvements)
20:44

18:00
[c11e55fabb] Remove an unnecessary OP_Null in the IN-operator logic. Attempt to clarify comments explaining the IN-operator code, though it is not clear that the comments are correct even yet - more work to be done. (user: drh, tags: trunk)
15:51
[7c6fbcfe6e] Clean up the IN operator code generation logic to make it easier to reason about. In the process, improve code generation to omit some unused OP_Null operations. (user: drh, tags: trunk)
15:34
[e13175d357] Closed-Leaf: The idea of coding IN operator with a short list on the RHS as an OR expression turns out to be helpful. If the list is of length 1 or 2, the OR expression is very slightly faster, but the ephemeral table approach is clearly better for all list lengths greater than 2. Better to keep the code simple. (user: drh, tags: IN-operator-improvements)
14:46
[ee0fd6aaf9] Begin making changes to the IN operator in an attempt to make it run faster and to make the code easier to understand. (user: drh, tags: IN-operator-improvements)
01:40

2014-07-31
22:59

20:16

15:44
[f4cb53651b] Deactivate the DISTINCT in a SELECT on the right-hand side of an IN operator, since it should not make any difference in the output but dues consume extra memory and CPU time. (user: drh, tags: trunk)
2014-07-30
23:11
[5360ecb0b8] Re-integrate the recent changes from the 'winMutex' branch back into the Win32 mutex subsystem. (user: mistachkin, tags: trunk)
21:10
[3aad01960f] Add three new static mutexes for use by the application. This is a partial import of changes from the threads branch. (user: drh, tags: trunk)
15:43
[c7303d0139] Add the "eForce" parameter to the sqlite3_multiplex_shutdown() entry point in test_multiplex.c. Shutdown is forced if true. Shutdown is not done if there are pending database connections and eForce is false, but an error log entry is made instead. (user: drh, tags: trunk)
14:57

13:56
[6b785e92f2] Ensure that the correct number of columns in a UNIQUE index are checked for uniqueness, regardless of whether or not the original table has a ROWID or if the columns are NOT NULL, etc. Ticket [9a6daf340df99ba93c]. (user: drh, tags: trunk)
11:49

2014-07-22
22:46
[48f40861db] When running ANALYZE, it is not necessary to check the right-most key column for changes since that column will always change if none of the previous columns have. (user: drh, tags: trunk)
20:02
[77f412caf0] Add the OP_ReopenIdx opcode that works like OP_OpenRead except that it becomes a no-op if the cursor is already open on the same index.

19:14
[eed754fe93] The optimization of check-in b67a6e33f2 does not work (it generates incorrect VDBE code) if an OR term is AND-ed with a constant expression. So back that optimization out and add a test case to make sure it does not get added back in. (user: drh, tags: trunk)
