28 check-ins using file src/vdbe.c version bf284ede
2014-04-29
| ||
16:10 | Ignore likelihood() values on indexed IPK lookups. (check-in: 5bb7757a user: dan tags: experimental-costs) | |
12:01 | Fix a test case so that it updates sqlite_stat1 consistently. (check-in: 2dc5a0b5 user: dan tags: experimental-costs) | |
2014-04-28
| ||
20:11 | Do not reduce the number of rows scanned at all for "IS NOT NULL" constraints. Fix a bug in calculating the number of rows visited by scans of partial indicies. (check-in: a8ae93f0 user: dan tags: experimental-costs) | |
19:34 | The trunk assumes that an open range constraint on an indexed term (col>?) term matches 1/4 of the indexed rows, and that a closed constraint (col BETWEEN ? AND ?) matches 1/64. Change this branch to do the same. (check-in: 4047ac75 user: dan tags: experimental-costs) | |
15:11 | Update unordered.test to take into account for the fact that SQLite now prefers a full-table scan over a non-covering index scan that visits a large percentage of the table rows. (check-in: 20f468df user: dan tags: experimental-costs) | |
12:08 | Add an extra column to a table in analyze9.test to give the planner a little more reason to select an index. (check-in: 1b95544f user: dan tags: experimental-costs) | |
10:00 | Update test script analyze3.test to account for the fact that SQLite now prefers a full-table scan over a non-covering index scan that visits a large percentage of the table rows. (check-in: 35f46a55 user: dan tags: experimental-costs) | |
09:35 | Modify internal function whereLoopAdjustCost() so that it does not prefer a skip-scan over a regular index scan even if the regular scan uses a subset of the WHERE terms used by the skip-scan. (check-in: 88a5758d user: dan tags: experimental-costs) | |
08:49 | Fix an error in estimating of the number of rows visited by a range scan. (check-in: d491de62 user: dan tags: experimental-costs) | |
2014-04-26
| ||
20:21 | Fix an sqlite3_stmt_status() problem caused by recent changs on this branch. (check-in: dee20409 user: dan tags: experimental-costs) | |
2014-04-25
| ||
20:22 | If the user provides likelihood() data for a WHERE clause term used as part of an index key, have the planner use it when calculating the expected number of rows visited by the loop. (check-in: c51efaa5 user: dan tags: experimental-costs) | |
15:01 | Store values loaded from the stat1 table as logarithmic values in memory. (check-in: 1bd74c49 user: dan tags: experimental-costs) | |
2014-04-24
| ||
20:04 | Changes to the way the planner calculates the costs of various table and index scans. Some test cases still failing. (check-in: c5a6ec0a user: dan tags: experimental-costs) | |
2014-04-23
| ||
12:00 | Enhancements to the date and time functions so that they optionally support a 5-digit year. Not sure we want to include this in trunk. Saved in a branch for future reference. (Closed-Leaf check-in: 2029a396 user: drh tags: five-digit-year) | |
2014-04-22
| ||
19:42 | Change from using the win32-none VFS to just a query parameter. (check-in: ffceacf6 user: drh tags: win32-none) | |
19:34 | Add some OSTRACE calls for consistency. (check-in: be292d55 user: mistachkin tags: win32-none) | |
19:30 | Add the win32-none VFS which omits rollback-journal locking. (check-in: 03e3c5a8 user: drh tags: win32-none) | |
2014-04-21
| ||
18:00 | Preliminary changes to support building VSIX packages for Windows 8.0 and Windows Phone 8.0 using Visual Studio 2013. (check-in: 3bf97c81 user: mistachkin tags: vsixWinPhone81) | |
13:36 | Comment tweaks on the test case for the [b75a9ca6b0] bug fix. (check-in: 65d2544a user: drh tags: trunk) | |
13:21 | Avoid discarding an ORDER BY clause in the case where an identical GROUP BY clauses uses an index to group, but not sort, the rows. Fix for [b75a9ca6b0]. (check-in: de9a490f user: dan tags: trunk) | |
2014-04-18
| ||
22:20 | Clean up the proper-subset cost adjustment logic to make it more compact and easier to read and so that full branch test coverage is more easily obtained. (check-in: 9a5d38c7 user: drh tags: trunk) | |
00:49 | Add the SQLITE_RUNTIME_BYTEORDER compile-time option to force SQLite to check the processor byte-order at run-time. Add additional compile-time byte order checks for ARM, PPC, and SPARC. (check-in: 2c536387 user: drh tags: trunk) | |
00:08 | Preliminary changes to support building VSIX packages for Windows Phone 8.1. (check-in: a1b2f28b user: mistachkin tags: vsixWinPhone81) | |
00:06 | Add the SQLITE_TESTCTRL_BYTEORDER test control to interrogate SQLite's notion of the processor byte order and whether the byte order is known at compile-time or determined at run-time. (check-in: 9c696196 user: drh tags: trunk) | |
2014-04-14
| ||
19:48 | Make sure the undocumented sqlite_rename_parent() function does not crash even if it is invoked with NULL arguments. Ticket [264b970c4379fd4b94] (check-in: c6fa8d0d user: drh tags: trunk) | |
2014-04-13
| ||
19:28 | Remove the unused second argument from sqlite3ExprCachePop(). Add an ALWAYS() on an always-true conditional in sqlite3VdbeResolveLabel(). (check-in: ab23abf3 user: drh tags: trunk) | |
19:15 | Make sure column cache elements are cleared correctly when jumping over code for key generation in a partial index. Fix for ticket [2ea3e9fe6379fc3f6]. (check-in: 3122b836 user: drh tags: trunk) | |
2014-04-10
| ||
02:24 | Modify the OR-clause handling so that it can safely deal with OR-clause with 17 or more terms. Fix for ticket [10fb063b1179be53ea0b53bb]. (check-in: a67b5312 user: drh tags: trunk) | |
