| 03:40 | Back out the sqlite3_stmt_mode() and EXPLAIN TABLES enhancements, but keep the other miscellaneous improvements to EXPLAIN that were implemented while adding the above: Turn magic numbers into symbolic constants. Add the sqlite3MemPrint() interface accessible to the debugger. Improve the performance and reduce the code size. (check-in: 62aece6677 user: drh tags: explain-improvements) | |
| 00:05 | Recompute the set of columns used for each table when the table is involved in query flattening. (check-in: a9bb71ba70 user: drh tags: trunk) | |
|
2020-03-20
| ||
| 20:54 | Allow "main" to be used to refer to the main database even after SQLITE_DBCONFIG_MAINDBNAME has been used to assign another alias. (check-in: 75c85ca32f user: dan tags: main-alias-fix) | |
| 20:18 | Avoid an undefined integer overflow in fts3 by detecting data structure corruption earlier. (check-in: 86e98ddc19 user: dan tags: trunk) | |
| 20:00 | Add the EXPLAIN TABLES syntax that uses SQLITE_STMTMODE_TABLELIST. Seems to work, but not well-tested. (Leaf check-in: e7343ce751 user: drh tags: sqlite3_stmt_mode) | |
| 17:49 | Further simplification of the EXPLAIN logic. Fix the test errors from the previous check-in. (check-in: 5eaba9af1c user: drh tags: sqlite3_stmt_mode) | |
| 16:13 | Revamp the EXPLAIN infrastructure to facilitate sqlite3_stmt_mode(). The currently code mostly works, but there are test failures. This is an incremental check-in. (check-in: e9e17e2125 user: drh tags: sqlite3_stmt_mode) | |
|
2020-03-19
| ||
| 21:17 | Initial code for a proposed new sqlite3_stmt_mode() API. This is an incomplete snapshot of a work-in-progress. (check-in: 3cf7537b5e user: drh tags: sqlite3_stmt_mode) | |
| 18:13 | Change the ESCAPE clause on the LIKE operator to override wildcard characters, in order to match the behavior of PosgreSQL. (check-in: 11e0844f71 user: drh tags: trunk) | |
| 17:27 | Fix an integer overflow problem with the dbstat virtual table that comes up when trying to analyze a corrupt database. (check-in: 1d64f4a8af user: drh tags: trunk) | |
| 15:57 | Fix a typo in a comment. No changes to code. (check-in: 3a51919ac2 user: drh tags: trunk) | |
|
2020-03-18
| ||
| 15:58 | Fix the build for when SQLITE_ENABLE_STAT4 is defined. (check-in: 8f0a8c2aa4 user: drh tags: approximate-analyze) | |
| 14:43 | Add the SQLITE_ANALYZE_LIMIT compile-time option (expected to be temporary) that sets a threshold at which ANALYZE starts to use approximations during the analysis process. (check-in: a773fd4698 user: drh tags: approximate-analyze) | |
|
2020-03-17
| ||
| 17:11 | Provide an estimated row count to stat_init() for STAT1 analysis. (check-in: 714419fe85 user: drh tags: approximate-analyze) | |
| 13:41 | Remove the SQLITE_OMIT_BTREECOUNT option. Btree count is required. (check-in: a9bfa47aee user: drh tags: approximate-analyze) | |
| 13:07 | Improved bytecode comments for the ANALYZE command. (check-in: c38ea4139d user: drh tags: approximate-analyze) | |
| 12:37 | Merge changes from trunk. (check-in: 93d710262e user: drh tags: approximate-analyze) | |
|
2020-03-16
| ||
| 18:52 | Fix handling of window functions in aggregate queries that have no GROUP BY clause. Also remove a faulty assert causing the error reported in [618156e3]. (check-in: 38e3dd389d user: dan tags: trunk) | |
| 03:07 | At the end of the right-hand table loop of a LEFT JOIN that uses an IN operator in the ON clause, put the OP_IfNoHope operator after the OP_IfNotOpen operator, not before, to avoid a (harmless) uninitialized register reference. Ticket [82b588d342d515d1] (check-in: 8b437b4726 user: drh tags: trunk) | |
|
2020-03-13
| ||
| 07:28 | Merge SQLITE_NOOP_UPDATE fix into this branch. (check-in: e2cc655e0d user: dan tags: begin-concurrent-report) | |
| 07:23 | Fix a typo causing SQLITE_NOOP_UPDATE builds to fail. (check-in: 1e2109fd33 user: dan tags: begin-concurrent-pnu) | |
|
2020-03-12
| ||
| 19:37 | Add link from begin_concurrent_report.md back to branch timeline. (check-in: 61869f8b48 user: dan tags: begin-concurrent-report) | |
| 17:54 | Remove stray comment characters at the end of an #ifdef that were accidently left in the previous check-in. (check-in: ea914bec81 user: drh tags: trunk) | |
| 17:28 | Fix comments and strengthen assert() statements associated with the OPFLAG_SEEKEQ and BTREE_SEEK_EQ flags. (check-in: 2317492138 user: drh tags: trunk) | |
|
2020-03-11
| ||
| 20:03 | Merge enhancements from trunk. (check-in: 4945a66237 user: drh tags: approximate-analyze) | |
| 19:56 | Do not factor out constant functions into the initialization section of a prepared statement, because even though they are constant, they can still throw exceptions. Instead, put such functions in an OP_Once block. This fixes ticket [3c9eadd2a6ba0aa5] and causes COALESCE() and CASE...END to be short-circuit. (check-in: c5f96a085d user: drh tags: trunk) | |
| 19:41 | Rename sqlite3ExprCodeAtInit() to sqlite3ExprCodeRunJustOnce(). Other changes to make the new code cleaner. Test cases added. (Closed-Leaf check-in: d7f1848997 user: drh tags: do-not-factor-functions) | |
| 19:30 | Add documentation notes and fix outstanding issues on this branch. (check-in: b288bbd1df user: dan tags: begin-concurrent-report) | |
| 17:58 | Do not factor out constant functions into the initialization section at the end of the prepared statement, be cause if they throw an exception, it will abort the statement even if the function is never called. Better to put constant functions in an OP_Once block. (check-in: 97a18a5cd7 user: drh tags: do-not-factor-functions) | |
| 16:46 | Support reporting of blob fields. (check-in: 724a4a844d user: dan tags: begin-concurrent-report) | |
| 02:04 | This variant to the fix for ticket [e0c2ad1aa8a9c691] uses fewer CPU cycles. (check-in: fb5a8a9edd user: drh tags: trunk) | |
|
2020-03-10
| ||
| 22:55 | Merge updates from trunk. (check-in: e05f743f61 user: drh tags: approximate-analyze) | |
| 21:14 | Fix test and other problems with reporting pages read and written. (check-in: 9ae970fdc1 user: dan tags: begin-concurrent-report) | |
| 19:55 | Fix problem in test script concreport.test. (check-in: 32d1b7210a user: dan tags: begin-concurrent-report) | |
| 19:24 | Enhanced detection logic for preventing the use of static schema expressions by code generating routines. (check-in: 5f60b527b9 user: drh tags: trunk) | |
| 19:23 | Prevent the read-only expressions held in the schema from being passed down into code generating subroutines where they might be changed. Pass a copy of the expression instead. (check-in: 2b750b0f74 user: drh tags: branch-3.31) | |
| 18:55 | Further changes to ensure that expressions held in table and index definitions do not get passed down into code generator logic where they might be modified. (check-in: f45f5de000 user: drh tags: trunk) | |
| 13:35 | Make a copy of the expression that defines a value of a generated column before sending it to the code generator routines. (check-in: 03d201c041 user: drh tags: trunk) | |
| 11:50 | Apply the correct affinity transformations when pulling values off of the sorter index used for GROUP BY. Ticket [e0c2ad1aa8a9c691] (check-in: 101f7dea75 user: drh tags: trunk) | |
| 02:57 | The sqlite3ExprCodeFactorable() routine should make a copy of non-factorable expressions, as they might be coming from a DEFAULT or generated column in a table constraint. (check-in: a2d6f108c5 user: drh tags: trunk) | |
| 01:24 | Background work for experiments trying to enhance ANALYZE so that it runs off of samples of the entire index and does not need to read the entire index. (check-in: 29d1cc5c36 user: drh tags: approximate-analyze) | |
|
2020-03-09
| ||
| 21:00 | Report on pages, as well as keys, read and written by BEGIN CONCURRENT transactions. (check-in: b661ccc88f user: dan tags: begin-concurrent-report) | |
| 18:26 | Cleaner separation of the STAT4-specific logic in the implementation of ANALYZE. (check-in: 3df07e5a9a user: drh tags: trunk) | |
| 15:39 | Enhancements to the ".import" command of the CLI. (check-in: cab1834cfc user: drh tags: trunk) | |
| 03:21 | Fix typos in RowSet. (check-in: 86465c08f4 user: pdr tags: trunk) | |
| 01:02 | Fix typos in the Lemon documentation. (check-in: 35f1f151ac user: drh tags: trunk) | |

|
2020-03-06
| ||
| 20:51 | Enhancement to log logical writes as well as reads. (check-in: 1c1f180eb6 user: dan tags: begin-concurrent-report) | |
|
2020-03-05
| ||
| 20:59 | Fix reporting for indexed range scans that extend past the end of the data. (check-in: ab458a319f user: dan tags: begin-concurrent-report) | |
