| 19:15 | Simplify the query flattener so that it does not duplicate the WHERE clause of subquery that is being incorporated into the outer query - copies it directly. This is more efficient. And it also fixes the specific test case show for ticket [f09fcd17810f65f71789525] but it does not resolve the more general problem that sqlite3ExprDup() does not correctly duplicate expressions that contain subqueries with window functions. (check-in: f1b18d44ff user: drh tags: ticket-f09fcd17810f) | |
| 18:58 | Experiment with using an atomic CPU primitive instead of a mutex for intra-process locking with the unix-excl VFS. (check-in: 8f4cb9dd33 user: dan tags: mutexfree-shmlock) | |
| 17:06 | When masking bits off of sqlite3.flags, make sure the mask is 64 bits in size so as not to accidentally mask of high-order bits. (check-in: 53d3b169d8 user: drh tags: trunk) | |
| 16:54 | Add test file wal2snapshot.test that should have been added as part of an earlier commit. (check-in: f6baa7e116 user: dan tags: wal2) | |
| 16:50 | When saving off the value of sqlite3.flags, take care to preserve all 64 bits. (check-in: 9c6dbcfab5 user: drh tags: trunk) | |
| 16:11 | Issue a warning whenever a double-quoted string literal is used. (check-in: ac9ad50430 user: drh tags: trunk) | |
| 14:24 | Bump the version number to 3.26.1. (check-in: e97e053b78 user: drh tags: branch-3.26) | |
| 14:11 | Fix a potential NULL pointer dereference that can occur in ALTER TABLE following an OOM. Test case in TH3. (check-in: 99a0951fdc user: drh tags: branch-3.26) | |
| 13:57 | Ensure that ALTER TABLE modifies table and column names embedded in WITH clauses that are part of views and triggers. (check-in: e066b4e171 user: drh tags: branch-3.26) | |
| 03:59 | Invoking the sqlite3_trace() or sqlite3_trace_v2() interfaces cancels any sqlite3_profile() that is running. (check-in: ec63d3506b user: drh tags: trunk) | |
| 03:13 | Merge fixes from trunk. (check-in: f2083ee410 user: drh tags: begin-concurrent-pnu) | |
| 02:08 | Merge bug fixes from trunk. (check-in: 1e13aaa29f user: drh tags: begin-concurrent) | |

| 01:53 | Fix a potential NULL pointer dereference that can occur in ALTER TABLE following an OOM. Test case in TH3. (check-in: ea50815bf8 user: drh tags: trunk) | |
| 01:08 | Fix a missing mutex in the sqlite3_normalized_sql() interface when it is called on a prepared statement that did not previously have a computed normalization of the input SQL. (check-in: 1a1a59c6c5 user: drh tags: trunk) | |
| 00:08 | Merge ALTER TABLE and sqlite3_normalized_sql() bug fixes from trunk. (check-in: 3793e5d5d6 user: drh tags: begin-concurrent-pnu) | |

| 23:56 | Get rid of the hash table used to track IN operators in the sqlite3_normalized_sql() implementation. Use simple integer variables instead. (check-in: 272dc74fd0 user: drh tags: trunk) | |
| 23:45 | The sqlite3_normalized_sql() interface should not be transforming quoted identifier names into wildcards. Fix this, and at the same time simplify the code substantially. (check-in: e8540377ec user: drh tags: trunk) | |
| 23:25 | Bungled checkin. Ignore. (Closed-Leaf check-in: 9b6e9a6e45 user: drh tags: mistake) | |
| 21:55 | Fix an imbalanced lock problem in sqlite3Normalize() introduced by the simplification in [94ea6379178e3ff6a]. (check-in: f69624373e user: drh tags: trunk) | |

| 18:25 | Add test cases to wal2concurrent.test. (check-in: ef9e7a87a4 user: dan tags: begin-concurrent-wal2) | |
| 17:48 | Simplifications to the sqlite3_normalized_sql() implementation. (check-in: 94ea637917 user: drh tags: trunk) | |
| 17:36 | Fix a test script problem on this branch. (check-in: 692ddc2808 user: dan tags: begin-concurrent-wal2) | |
| 17:31 | Fix a test script problem on this branch. (check-in: 285d1c5904 user: dan tags: wal2) | |
| 17:20 | Fix a problem causing "PRAGMA journal_mode" to report the wrong journal mode (wal instead of wal2) under some circumstances. (check-in: bf309107df user: dan tags: begin-concurrent-wal2) | |
| 17:14 | Fix a problem causing "PRAGMA journal_mode" to report the wrong journal mode (wal instead of wal2) under some circumstances. (check-in: 1d8d4f6896 user: dan tags: wal2) | |
| 16:45 | Fixes for snapshots API on this branch. Also ensure that the snapshots API cannot be used with wal2 mode databases (for now anyhow). (check-in: d8c2d55fa4 user: dan tags: begin-concurrent-wal2) | |
| 16:31 | Fixes for snapshots API on this branch. Also ensure that the snapshots API cannot be used with wal2 mode databases (for now anyhow). (check-in: 19c61ab794 user: dan tags: wal2) | |
| 13:49 | Merge enhancements from trunk, especially the sqlite3_normalized_sql() enhancement. (check-in: 342c9538d9 user: drh tags: begin-concurrent-pnu) | |
| 13:49 | Ensure that ALTER TABLE modifies table and column names embedded in WITH clauses that are part of views and triggers. (check-in: f44bc7a8b3 user: dan tags: trunk) | |
| 13:44 | Merge enhancements from trunk, especially the enhanced sqlite3_normalized_sql() interface. (check-in: 47b73f6bfe user: drh tags: begin-concurrent) | |
| 13:39 | Enhance the sqlite3_normalize_sql() interface so that it works even if the prepared statement was not initially compiled using SQLITE_PREPARE_NORMALIZED. Enhance the ".trace" command in the CLI so that it is able to access the full scope of functionality provided by sqlite3_trace_v2() and in particular so that it is able to show normalized SQL output using the newly enhanced sqlite3_normalize_sql() interface. (check-in: 7da617e97e user: drh tags: trunk) | |

| 21:16 | When compiled with SQLITE_ENABLE_NORMALIZE, always have sqlite3_exec() enable the SQLITE_PREPARE_NORMALIZE flag. (Leaf check-in: 28643d837d user: mistachkin tags: execWithNormalize) | |
| 19:41 | First attempt at making features work together. Only the most minimal testing so far. (check-in: fd707001f0 user: dan tags: begin-concurrent-wal2) | |
| 16:51 | Add the "index_usage" utility program. (check-in: df95455213 user: drh tags: trunk) | |
| 14:33 | Performance improvement in sqlite3_step() by creating a new mTrace flag for the legacy xProfile pointer that is set by sqlite3_profile(). (check-in: e28584e8bc user: drh tags: trunk) | |

| 20:49 | Merge the wal2 and begin-concurrent code. Both features work, but not at the same time. (check-in: b7281a1caa user: dan tags: begin-concurrent-wal2) | |
| 20:38 | Minor change to wal.c on this branch to make it more similar to trunk. (check-in: 6a7af3ead5 user: dan tags: begin-concurrent) | |
| 19:29 | Cherrypick a couple of fixes from begin-concurrent-pnu into this branch. The differences between the two branches are now that this one does not have "PRAGMA noop_update" or the mutex-free PRNG. (check-in: a56506b938 user: dan tags: begin-concurrent) | |
