| 20:46 | Sync up the MSVC makefiles. (check-in: f66d0d8cf6 user: mistachkin tags: callbackConv) | |
| 20:40 | Merge updates from trunk. (check-in: ea635bf97e user: mistachkin tags: callbackConv) | |
| 19:57 | Fix an assert() so that it does C-compiler does not combine an assert() conditional with a production code conditional and thereby confuse the mutation testing script. (check-in: 2fa5288a7e user: drh tags: rowvalue) | |
| 15:02 | Simplifications to the SQLITE_KEEPNULL flag on VDBE comparison operators. (check-in: 96269f0179 user: drh tags: rowvalue) | |
| 12:12 | Do vector comparison size checking early - at name resolution time - to forestall future problems. (check-in: ae127bcc0a user: drh tags: rowvalue) | |
| 12:02 | Catch vector size mismatch problems during name resolution to avoid later problems. (Closed-Leaf check-in: 56562a0346 user: drh tags: early-vector-size-check) | |
| 09:44 | Fix a crash that could occur under certain circumstances if the vectors on either side of a comparison operator were of a different size. (check-in: 42670935ab user: dan tags: rowvalue) | |
|
2016-09-03

| 19:52 | Fix a problem causing the affinity of sub-select row-value elements to be ignored in some contextes. (check-in: 7d9bd22c07 user: dan tags: rowvalue) | |
| 16:24 | Merge the fuzzershell enhancement from trunk. (check-in: ed20604848 user: drh tags: rowvalue) | |
| 16:23 | Build the generate_series(START,END,STEP) table-valued function into fuzzershell, to make it easier to construct compact test cases that contain actual data. (check-in: 672c21bcf0 user: drh tags: trunk) | |
| 15:31 | Consider the affinity of "b" when using an "a IN (SELECT b ...)" expression with an index on "a". Fix for [199df416]. (check-in: f5e4985541 user: dan tags: rowvalue) | |
| 01:46 | Performance optimizations. (check-in: f1d06c49ba user: drh tags: rowvalue) | |

| ||
| 23:56 | Merge recent changes from trunk. (check-in: c7271fbde1 user: drh tags: rowvalue) | |
| 21:34 | Add a test case for the OOM handled by the previous commit. (check-in: 9bdf7ca1b3 user: dan tags: trunk) | |
| 21:17 | Correctly detect an OOM occurring in the setDestPgsz() subroutine of backup. (check-in: d9d8a048d4 user: drh tags: trunk) | |
| 17:27 | The previous commit could miss an SQLITE_NOMEM error. This commit catches it. (Closed-Leaf check-in: 3a9f4750a6 user: dan tags: mistake) | |
| 17:18 | Within a backup operation, ensure that a read-transaction is opened on the source database before its page size is read. This ensures the page-size used to write to the backup database is the same as its actual page-size, which is important for ZipVFS databases. (check-in: 7908fc6049 user: dan tags: trunk) | |
|
2016-09-01
| ||
| 14:03 | Have "sqldiff --rbu" ignore rows with NULL values in primary key fields. RBU can't handle such rows and the documentation already says sqldiff ignores them. Because the code now uses "=" instead of "IS" to filter on primary key columns, diffs on virtual tables are faster now too. (check-in: f4ba894a86 user: dan tags: trunk) | |
| 09:35 | If SQLITE_ENABLE_ZIPVFS is defined, journal_mode=off is configured and a savepoint or statement rollback is attempted, move the pager into the error state to prevent the transaction from being committed. This makes it safe to use journal_mode=off with zipvfs under some conditions. (check-in: 38d31e189e user: dan tags: trunk) | |
|
2016-08-29
| ||
| 14:18 | Use some of the example code from the sessions documenatation in the sessions test cases. (check-in: 6602974d17 user: dan tags: trunk) | |

| 14:13 | Merge updates from trunk. (check-in: 082fd5f8ac user: drh tags: rowvalue) | |
| 14:05 | Fix the extra comments (added with -DSQLITE_ENABLE_EXPLAIN_COMMENTS) so that the sense of <, <=, >, and >= tests is correct and so that the SQLITE_STOREP2 version is shown correctly. These changes are already in the rowvalue branch but are added here since they are technically unrelated to rowvalue. (check-in: 4d43c4698e user: drh tags: trunk) | |
| 01:41 | Fix the "Synopsis" on the OP_Lt, OP_Le, OP_Gt, and OP_Ge opcodes, which has been backwards for time out of mind. (check-in: f51248dcfa user: drh tags: rowvalue) | |
|
2016-08-26
| ||

| 21:15 | Fix the sqlite3FindInIndex() to ensure that it always uses a prefix of the index and uses no repeated columns. Enhanced comments. (check-in: b9fc89e432 user: drh tags: rowvalue) | |
| 19:54 | Add an EXPLAIN QUERY PLAN line for when a index is used to implement an IN operator. (check-in: 171aa833a2 user: drh tags: rowvalue) | |
| 19:47 | Add test cases to rowvalue2.test. (check-in: 078bb69e99 user: dan tags: rowvalue) | |
| 19:31 | Enhance sqlite3FindInIndex() so that it is able to make use of the primary keys at the end of an index. (check-in: 4b589fbfcc user: drh tags: rowvalue) | |
| 18:17 | Fix a post-OOM crash in updateRangeAffinityStr(). Add several ALWAYS() macros on unreachable branches. (check-in: 87d40195ae user: drh tags: rowvalue) | |
| 17:54 | Fix a problem with affinity changes and vector range comparisons. (check-in: b34413ac7e user: dan tags: rowvalue) | |
| 13:19 | Allow ROWID values in indexed vector comparisons. (check-in: b0cc6be4eb user: drh tags: rowvalue) | |
| 12:00 | Fix a problem in internal function sqlite3OpenTableAndIndices causing an operand of an unrelated VM instruction to be overwritten. Fix for [ef360601]. (check-in: 7090147903 user: dan tags: trunk) | |
| 04:32 | Rename a test procedure in 'speed3.test' to avoid a name collision. (check-in: 84de17bc68 user: mistachkin tags: trunk) | |
| 03:42 | Comment improvements. Put ALWAYS and NEVER macros on three unreachable branches. (check-in: 397617009e user: drh tags: rowvalue) | |
| 02:10 | Adapt the special case of '$' in item names for test 'vtabH-3.1' as well. (check-in: e4aeaa2bc7 user: mistachkin tags: trunk) | |
| 01:47 | Make the test 'vtabH-3.1' work when there are less than 5 top-level items. (check-in: 328f79bb57 user: mistachkin tags: trunk) | |
| 01:17 | Support running the fstree tests in 'vtabH.test' on Windows when not using the system drive. (check-in: 3680f95ff3 user: mistachkin tags: trunk) | |
| 01:02 | Remove an unreachable branch from sqlite3ExprAffinity() (check-in: 9d96f61481 user: drh tags: rowvalue) | |

| 22:31 | Merge recent changes from trunk. (check-in: 5789aab8ef user: drh tags: rowvalue) | |
| 22:06 | Fix the sqlite3_trace_v2() interface so that it goes disabled if either the callback or mask arguments are zero, in accordance with the documentation. (check-in: 37e6c54b1a user: drh tags: trunk) | |
| 21:14 | Refactor the sqlite3ExprCodeIN() routine for improved maintainability. (check-in: b56705ae63 user: drh tags: rowvalue) | |

| 14:23 | Corrections to the IN-operator notes. (check-in: 25033ee945 user: drh tags: rowvalue) | |
| 14:00 | Add notes on the implementation of the IN operator. (check-in: d256b2caeb 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: f41a0391b7 user: dan tags: rowvalue) | |
| 00:51 | The previous OOM fix was bad. Back it out and replace it with a better one. (check-in: 1e3bc3698a user: drh tags: rowvalue) | |
| 00:25 | Avoid a potential null-pointer dereference following an OOM. (check-in: 25f6ed8de4 user: drh tags: rowvalue) | |

| 18:09 | Fix harmless compiler warnings in changebatch. (check-in: a721a73818 user: drh tags: changebatch) | |
| 17:30 | Fix an uninitialized variable in CASE expression code generation. (check-in: c8ffae05e1 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: efa761b2f5 user: dan tags: changebatch) | |
| 14:42 | Fix the SQLITE_USER_AUTHENTICATION login check so that the SQLITE_AUTH_USER error code correctly propagates and is not overwritten by SQLITE_ERROR. (check-in: c640489db2 user: drh tags: trunk) | |
|
2016-08-22
| ||
| 21:01 | Add a couple of extra tests to changebatch1.test. (check-in: 207d970b79 user: dan tags: changebatch) | |

| 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: 2f39987f21 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: e50d264fdc user: drh tags: rowvalue) | |
| 21:11 | Further comment enhancements. No changes to code. (check-in: d4562a9e7b user: drh tags: rowvalue) | |
| 21:02 | Clarification of code comments in expr.c. Clean up the implementations of sqlite3ExprIsVector() and sqlite3ExprVectorSize() slightly. (check-in: 4fb66d6592 user: drh tags: rowvalue) | |

| 00:51 | Add support for vector assignments in the SET clause of an UPDATE statement. (check-in: f320d47d6b 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: d8feea7dcd user: drh tags: rowvalue) | |
