2017-04-20
| ||
| 17:35 | Merge latest trunk changes into this branch. (check-in: b1533bc4 user: dan tags: schemalint) | |
| 17:03 | • Edit [8e57c31340dd9ffc|8e57c313]: Mark "Closed". (artifact: 161bfc2f user: dan) | |
| 17:03 | Avoid creating a temp table in the user database in the sqlite3_expert code. (check-in: 4e366996 user: dan tags: schemalint) | |
| 16:43 | Speed this branch up a bit by filtering before the virtual table layer when sampling user data. (Closed-Leaf check-in: 8e57c313 user: dan tags: schemalint-failure) | |
| 16:42 | • Edit [c62e358243d96cb3|c62e3582]: Remove the "Closed" mark. (artifact: c4e5e2c1 user: dan) | |
| 16:18 | Avoid adding INTEGER PRIMARY KEY columns to candidate indexes. (check-in: 4577fea5 user: dan tags: schemalint) | |
| 16:08 | • Edit [c62e358243d96cb3|c62e3582]: Mark "Closed". (artifact: 706ff30d user: dan) | |
| 16:08 | Avoid creating a temp table in the user database in the sqlite3_expert code. Trouble is, this makes sampling for stat1 data much slower. (check-in: c62e3582 user: dan tags: schemalint-failure) | |
| 09:54 | Add an option to generate stat1 data based on a subset of the user database table contents to sqlite3_expert. (check-in: c69c3e21 user: dan tags: schemalint) | |
|
2017-04-19
| ||
| 13:25 | Further improvements to coverage of fts3 module. (check-in: 6b21d0fd user: dan tags: trunk) | |
| 07:33 | Further modifications and test cases to improve test coverage of fts3. (check-in: ea8a0d2c user: dan tags: trunk) | |
|
2017-04-18
| ||
| 20:10 | Have sqlite3_expert_analyze() populate the sqlite_stat1 table before running queries through the planner for the second time. (check-in: a157fcfd user: dan tags: schemalint) | |
| 13:50 | Use sqlite3_table_column_metadata() instead of a SELECT statement to check for the existence of a %_stat table in fts3. This leads to smaller and easier to test code. (check-in: dc2a4802 user: dan tags: trunk) | |
| 09:04 | Fix sqlite3_expert handling of triggers on views. (check-in: ff4976da user: dan tags: schemalint) | |
| 05:49 | Refactor the fts3ColumnMethod() function so that all branches can be covered. (check-in: e47fdb49 user: dan tags: trunk) | |
|
2017-04-17
| ||
| 18:42 | Consolidate two branches of code in the "PRAGMA foreign_key_check" implementation. (check-in: 69f51f83 user: dan tags: trunk) | |
| 18:06 | • Edit [690870bd7b2e607b|690870bd]: Edit check-in comment. (artifact: d6d82fcc user: dan) | |
| 18:02 | Fix a problem in "PRAGMA foreign_key_check" in handling a WITHOUT ROWID child table with an INTEGER PRIMARY KEY parent key. Also, if an FK violation is detected in a WITHOUT ROWID child table, do not try to read and return the rowid. The second column returned by "PRAGMA foreign_key_check" in this case (WITHOUT ROWID child table) is now always set to NULL. (check-in: 690870bd user: dan tags: trunk) | |
| 17:03 | Add support for analyzing trigger programs to the sqlite3_expert code. (check-in: 159e8022 user: dan tags: schemalint) | |

| 15:47 | Merge latest trunk changes into this branch. (check-in: 2d0c458e user: dan tags: schemalint) | |
| 14:30 | Add header comment for sqlite3_vtab_collation(). (check-in: d238694c user: dan tags: schemalint) | |
| 14:16 | Fix memory leaks in the code on this branch. Make use of the sqlite3_index_constraint.usage field. Do not try to handle ORDER BY terms with explicit COLLATE clauses - they don't get passed to the vtab layer anyway. (check-in: 0cd75a87 user: dan tags: schemalint) | |
|
2017-04-14
| ||
| 19:41 | Modify the code in ext/expert/ to use the vtab interface instead of sqlite3_whereinfo_hook(). Remove sqlite3_whereinfo_hook(). (check-in: 3bb65850 user: dan tags: schemalint) | |
|
2017-04-13
| ||

| 15:36 | Update the code in test_delete.c to use the "win32" VFS if SQLITE_OS_WIN is defined. (check-in: fa9bb7b7 user: dan tags: trunk) | |
| 09:45 | Allow a user column name to be used on the LHS of a MATCH operator in FTS5. (check-in: 6f54ffd1 user: dan tags: trunk) | |
|
2017-04-12
| ||
| 17:50 | Update fts5 to support "<colset> : ( <expr> )" for column filtering, as well as "<colset> : NEAR(...)" and "<colset> : <phrase>". (check-in: c847543f user: dan tags: trunk) | |
|
2017-04-11
| ||
| 20:48 | Avoid updating unaffected indexes on a table as part of an UPDATE that requires foreign key processing in some cases. (check-in: 7aae5c0f user: dan tags: trunk) | |
| 19:58 | Avoid updating unaffected indexes on a table as part of an UPDATE that requires foreign key processing in some cases. (Closed-Leaf check-in: 477bea9e user: dan tags: fkey-optimization) | |

| 17:43 | Add header comments to the API functions in sqlite3expert.h. Include a list of all candidate indexes in the report output by the sqlite3_expert program. (check-in: 0c45c5eb user: dan tags: schemalint) | |
| 11:52 | Fix a segfault that could occur if an indexed expression was used in a comparison operation within the result-set of a SELECT statement. (check-in: d6bb7c42 user: dan tags: trunk) | |
|
2017-04-10
| ||
| 20:00 | Add ext/expert/README.md. (check-in: 9318f1b9 user: dan tags: schemalint) | |
| 16:13 | Changes to allow the code in sqlite3expert.c to be tested directly (via the API in sqlite3expert.h) instead of by invoking the sqlite3_expert application. Fix memory leaks and other problems. (check-in: 5dd98317 user: dan tags: schemalint) | |
|
2017-04-09
| ||
| 08:38 | Fix the -file option on the sqlite3_expert program. (check-in: 0857c48e user: dan tags: schemalint) | |
|
2017-04-08
| ||
| 19:00 | Merge latest trunk with this branch. (check-in: e051e8f2 user: dan tags: schemalint) | |
| 18:56 | Rename shell6.test to expert1.test. Have it invoke the sqlite3_expert binary if it is present. (check-in: be0deff9 user: dan tags: schemalint) | |
| 17:41 | Use hash tables instead of in-memory database tables for a few purposes in sqlite3expert.c. (check-in: bf10e68d user: dan tags: schemalint) | |
| 14:11 | Expand on the comment above OP_Destroy to explain why it throws an error if there are any active reader VMs. (check-in: b9a8c2b9 user: dan tags: trunk) | |
| 13:52 | Have the rtree module close any open blob-handle within the xSavepoint method. This prevents such an open blob handle from interfering with DROP TABLE operations. (check-in: fa4416ad user: dan tags: trunk) | |
| 09:12 | Have fts5 close any open blob-handle when a new savepoint is opened. This ensures that fts5 does not prevent DROP TABLE statements (which always open a savepoint) from succeeding. (check-in: a921ada8 user: dan tags: trunk) | |
|
2017-04-07
| ||
| 20:14 | Refactor code to suggest indexes from the shell tool into an extension in ext/expert. Unfinished. (check-in: 305e19f9 user: dan tags: schemalint) | |
|
2017-04-06
| ||
| 18:44 | Changes to allow indexes to be recommended for queries on SQL views. (check-in: 0884ff1d user: dan tags: schemalint) | |
| 14:56 | Fix the ".lint fkey" shell command for cases where the child key is also an INTEGER PRIMARY KEY. (check-in: 48826b22 user: dan tags: trunk) | |
| 12:06 | Fix the ".lint fkey" shell tool command so that it works for foreign keys that refer implicitly to primary key columns with non-BINARY default collation sequences. (check-in: 327eff25 user: dan tags: trunk) | |
|
2017-04-04
| ||
| 19:58 | Fix a problem causing "PRAGMA integrity_check" to disable the xfer optimization for subsequent VACUUM operations on tables with one or more CHECK constraints. This could result in VACUUM producing slightly larger database files. (check-in: e5bb7db5 user: dan tags: trunk) | |
| 17:50 | Add some support for OR terms to sqlite3_whereinfo_hook(). (check-in: 5cd07000 user: dan tags: schemalint) | |
| 04:23 | Add the sqlite3_whereinfo_hook() API - an experimental API replacing the DBCONFIG_WHEREINFO hack on this branch. (check-in: a54aef35 user: dan tags: schemalint) | |
|
2017-04-03
| ||
| 13:59 | Do not attempt to run sync2.test with SQLITE_DISABLE_DIRSYNC builds. (check-in: 658f08ce user: dan tags: trunk) | |
