14:23
Corrections to the IN-operator notes. (check-in: 25033ee9 user: drh tags: rowvalue)

Simplified VDBE code for the vector NOT IN null-scanning loop. (check-in: 7ae504e6 user: drh tags: rowvalue)
21:24
Improved extended comments of comparison operators when the SQLITE_STOREP2 flags is set on P5. No changes to non-debug code. (check-in: bbc1b016 user: drh tags: rowvalue)
19:14
Add the sqlite3changebatch_db() API. (check-in: bee44ebc user: dan tags: changebatch)
18:51
In sqlite3FindInIndex(), improve internal comments and avoid an unreachable branch. (check-in: 55945fc1 user: drh tags: rowvalue)
17:49
Fix more unreachable branches. (check-in: 6099c180 user: drh tags: rowvalue)
15:37
Add a NEVER() on an unreachable branch in comparisonAffinity(). (check-in: 505a2f20 user: drh tags: rowvalue)
12:22
Fix a buffer overrun in the code for handling IN(...) operators when the LHS of the operator contains indexed columns or expressions. (check-in: f41a0391 user: dan tags: rowvalue)
00:51
The previous OOM fix was bad. Back it out and replace it with a better one. (check-in: 1e3bc369 user: drh tags: rowvalue)
00:25
Avoid a potential null-pointer dereference following an OOM. (check-in: 25f6ed8d user: drh tags: rowvalue)
2016-08-23
19:02
Simplify the row value misuse error message. (check-in: 838c50a5 user: drh tags: rowvalue)
19:02
Add further tests for changebatch. And a fix to prevent a changeset from conflicting with itself. (check-in: 506d6ff4 user: dan tags: changebatch)
18:30
Fix a problem with rowvalue UPDATE when the rowvalue is not the left-most and the RHS is a multi-column subquery. (check-in: e149e6b9 user: drh tags: rowvalue)
18:09
Fix harmless compiler warnings in changebatch. (check-in: a721a738 user: drh tags: changebatch)
17:30
Fix an uninitialized variable in CASE expression code generation. (check-in: c8ffae05 user: drh tags: rowvalue)
17:02
Add a new method to sessions - sqlite3sessions_fullchangeset() - to return a changeset that always contains values for all old.* fields. Update changebatch to use these values to more reliably detect multi-column UNIQUE constraint violations. (check-in: efa761b2 user: dan tags: changebatch)
2016-08-22
21:01
Add a couple of extra tests to changebatch1.test. (check-in: 207d970b user: dan tags: changebatch)
20:49
Add an experimental module to detect conflicts between sessions changesets. (check-in: 0c9fd6b7 user: dan tags: changebatch)
20:10
Add support for the SQLITE_DBCONFIG_MAINDBNAME configuration option. (check-in: 78395193 user: drh tags: trunk)
14:30
Fix the vector BETWEEN operator so that it only evaluates the left-most vector expression once. Add support for vector comparisons in the CASE operator. (check-in: 07e69f43 user: drh tags: rowvalue)
00:48
Reinstate the mechanism in BETWEEN that avoids evaluating the first expression more than once, but fix the affinity extractor so that it works with this mechanism. The de-duplication of the first expression still does not work for vector expressions, though. (check-in: 2f39987f user: drh tags: rowvalue)
2016-08-20
22:49
The docs promise the in "x BETWEEN y AND z" the x expression is only evaluated once. That is no longer true, and so some tests are failing. This needs to be fixed before merging to trunk. (check-in: e50d264f user: drh tags: rowvalue)
21:11
Further comment enhancements. No changes to code. (check-in: d4562a9e user: drh tags: rowvalue)
21:02
Clarification of code comments in expr.c. Clean up the implementations of sqlite3ExprIsVector() and sqlite3ExprVectorSize() slightly. (check-in: 4fb66d65 user: drh tags: rowvalue)
18:06
Fixes for problems following OOM errors. (check-in: 9041ee4a user: drh tags: rowvalue)
17:00
Do not duplicate the Expr.pLeft subtree of a TK_SELECT_COLUMN node. (check-in: 8384c77e user: drh tags: rowvalue)
15:01
Fix a segfault that could occur if a query that used a vector comparison contained certain types of syntax errors. (check-in: 203f07c5 user: dan tags: rowvalue)
12:00
Improvements to the vector comparison splitter in exprAnalyze(). (check-in: a3ffd283 user: drh tags: rowvalue)
01:06
Improvements to comments. No code changes. (check-in: 4165d20f user: drh tags: rowvalue)
00:51
Add support for vector assignments in the SET clause of an UPDATE statement. (check-in: f320d47d user: drh tags: rowvalue)
00:07
Change the way TK_SELECT_COLUMN is handled so that the subquery is only generated once even if part of the vector comparison is used for indexing and the other part is now. This change also is a pathway to vector assignment in UPDATE statements. (check-in: d8feea7d user: drh tags: rowvalue)
2016-08-19
19:58
Replace the magic number (-2) with its symbol XN_EXPR in the exprMightBeIndexed() routine. No logic changes. (check-in: d4a5af69 user: drh tags: rowvalue)
19:12
Improved comments on sqlite3CodeSubquery(). No changes to code. (check-in: acea4ee1 user: drh tags: rowvalue)
18:40
Show the WhereTerm.iField value on debugging output, when it is non-zero. (check-in: 931c9535 user: drh tags: rowvalue)
18:28
Fix an obsolete comment on codeEqualityTerm(). No changes to code. (check-in: d07be5af user: drh tags: rowvalue)
15:41
Merge recent enhancements from trunk. (check-in: b1787236 user: drh tags: rowvalue)
15:17
Merge the VACUUM attached database enhancement from trunk. (Closed-Leaf check-in: 12d5e38d user: drh tags: dbconfig_maindbname)
15:15
Enhance the VACUUM command so that it can operate on an attached database. (check-in: 083f9e62 user: drh tags: trunk)
15:12
Disable row counting on queries run while doing a VACUUM. (Closed-Leaf check-in: ad35ef11 user: drh tags: vacuum-attached-db)
14:20
Add the capability to VACUUM an attached database by specifying the schema name as an argument to the VACUUM command. Since version 2.0, VACUUM has accepted an argument which was silently ignored. Now it has meaning. (check-in: 29d63059 user: drh tags: vacuum-attached-db)
