Fix an uninitialized variable causing a problem during fts5 table initialization. (check-in: a14fa876 user: dan tags: fts5)

2014-08-08
18:26
Update requirements marks. No changes to code. (check-in: 7556bd9a user: drh tags: trunk)
17:49
Improvements to the way the query planner handles sorting costs, so that very large sorting costs do not overwhelm the loop costs. (check-in: bdaa6947 user: drh tags: trunk)
17:25
Fix a buffer overrun in the previous commit. (Closed-Leaf check-in: 43c59c85 user: dan tags: query-planner-fix)
16:52
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]. (check-in: 299b9570 user: dan tags: query-planner-fix)
15:38
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. (check-in: 36b7c5ce user: drh tags: trunk)
12:51
Reworking the documentation on integer result codes. This is a comment and documentation change only. There are no changes to code. (check-in: 54f1df7b user: drh tags: trunk)
2014-08-07
20:42
When the estimated sorting cost overwhelms the estimated lookup cost, ensure that lookup costs are still taken into account when selecting a lookup algorithm. (check-in: 2af630c5 user: drh tags: trunk)
20:37
Clarify the computation of compatible isOrdered by in the plan solver of the query planner. (Closed-Leaf check-in: b5e8fd57 user: drh tags: query-planner-fix)
20:25
Remove the extraneous debugging printf() from the previous check-in. (check-in: 8f04d2c0 user: drh tags: query-planner-fix)
18:47
Add "segment promotion" to fts5. This prevents the FTS index from growing indefinitely as data is added and deleted. (check-in: ba359d78 user: dan tags: fts5)
16:50
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. (check-in: ec5d84ba user: drh tags: query-planner-fix)
2014-08-06
20:04
Avoid writing delete markers to the oldest segment in an FTS index. (check-in: 1baeb1ce user: dan tags: fts5)
18:50
A couple more harmless compiler warnings eliminated. (check-in: bcf6d775 user: drh tags: trunk)
17:49
Fix two more harmless compiler warnings. Make sure the fts3_unicode2.c file is in sync with mkunicode.tcl. (check-in: a2a60307 user: drh tags: trunk)
16:30
Add support for savepoints to fts5. (check-in: 3b19eba0 user: dan tags: fts5)
14:36

12:00
Merge the second InterlockedCompareExchange() fix from trunk. (check-in: 69018967 user: drh tags: sessions)
11:58
Fix an obsolete comment in the func.c source file. No changes to code. (check-in: 5c6bb57d user: drh tags: trunk)
11:57
On the windows VFS, do not try to make InterlockedCompareExchange an overloadable function, since sometimes it is a macro. (check-in: ab1a751e user: drh tags: trunk)
11:49
Fix an obsolete comment in the func.c source file. No changes to code. (check-in: 7a145c94 user: drh tags: sessions)
03:16
Merge in the fix for the InterlockedCompareExchange() build issue. (check-in: 091aa5f1 user: drh tags: sessions)
03:06
In the Win32 VFS, work around InterlockedCompareExchange() being a macro on some platforms (e.g. x64). (check-in: 7be244ce user: mistachkin tags: trunk)
02:03
Merge all recent changes from trunk. (check-in: a353a851 user: drh tags: threads)

Merge the latest 3.8.6 beta changes from trunk. (check-in: 68a6d5e2 user: drh tags: sessions)
01:08
Fix typos in the opcode documentation. Comment changes only. No changes to code. (check-in: 717245d4 user: drh tags: trunk)
00:29
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. (check-in: 0ad1ed8e user: drh tags: trunk)
2014-08-05
21:31
Ensure that aggregate functions are not used when evaluating a default value for a table column. Candidate fix for ticket [3a88d85f36704eebe134f7]. (check-in: 29ba8128 user: drh tags: trunk)
19:35
Use doclist indexes for AND queries as well as phrases. (check-in: 5d38e6ed user: dan tags: fts5)
19:16
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. Use the new implementation in circumstances where it is likely to be faster, such as when the RHS of the IN changes between successive evaluations. (check-in: 95286821 user: drh tags: trunk)
19:00
Use doclist-indexes with "ORDER BY rowid ASC" fts5 queries as well. (check-in: d028ba65 user: dan tags: fts5)
11:04
Rename the internal Schema.flags field to Schema.schemaFlags. (check-in: 5ae80b3c user: drh tags: trunk)
00:53

2014-08-04
21:26
Part of the change in the previous check-in was incorrect and can result in an incorrect UPDATE for WITHOUT ROWID tables. This check-in fixes the problem. (check-in: ee5f6eae user: drh tags: IN-operator-improvements)
20:07
Fix fts5_index.c to use doclist-indexes when possible. Only some cases work so far. (check-in: 90b82d3e user: dan tags: fts5)
18:50
Further enhancements to IN-operator processing. (check-in: 7fdf26da user: drh tags: IN-operator-improvements)
