| 22:52 | Do a more thorough job of cleaning traces of the strength-reduced LEFT JOIN. (check-in: 08833dda3a user: drh tags: join-strength-reduction) | |
| 21:16 | If terms of the WHERE clause require that the right table in a LEFT JOIN not be a null row, then simplify the LEFT JOIN into an ordinary JOIN. (check-in: 5b7abecc7a user: drh tags: join-strength-reduction) | |

| 13:52 | Merge all recent enhancements from trunk. (check-in: b0c2f760a6 user: drh tags: begin-concurrent) | |
| 13:44 | Avoid unnecessary write to the sqlite_sequence table when an insert is done into an autoincrement table with an application-specified rowid that is less than the maximum. (check-in: ec7addc87f user: drh tags: trunk) | |
| 13:26 | Add the ability to disable the push-down optimization using the 0x1000 bit of SQLITE_TESTCTRL_OPTIMIZATIONS. Also some documentation fixes and an enhancement to ".eqp full" in the CLI. (check-in: ae34edb7f4 user: drh tags: trunk) | |

| 12:57 | • Edit [eddc35f3057e59fd|eddc35f305]: Move to branch push-down-disable. (artifact: 9a33a437a2 user: drh) | |
| 12:12 | Add a test case for the fix on this branch. (check-in: 7834cf6c28 user: dan tags: testFixes) | |
| 12:04 | In the CLI, avoid extra .selecttrace and .wheretrace output when in ".eqp full" mode. (check-in: 427bbf318a user: drh tags: push-down-disable) | |
| 11:58 | Closer reading of the sqlite3_db_config() documentation show that it is subtly incorrect. This check-in fixes the problem. No code changes. (check-in: 44d90e7f4b user: drh tags: push-down-disable) | |
| 11:51 | Fix a minor formatting issue on the sqlite3_db_config() documentation. No changes to code. (check-in: 8a439a6dda user: drh tags: push-down-disable) | |
| 11:24 | Add the ability to disable the push-down optimization using the 0x1000 bit of SQLITE_TESTCTRL_OPTIMIZATIONS. (check-in: eddc35f305 user: drh tags: push-down-disable) | |

| 22:58 | Add the --native-malloc option to fuzzcheck. Fix ossfuzz.c and fuzzcheck.c so that they both deallocate the temp_store_directory before closing. (check-in: 0dd18ec882 user: drh tags: trunk) | |

| 16:34 | Avoid the possibility of signed integer overflow with oversized precisions in %d conversions in the printf() implementation. (check-in: ef3a7c877a user: drh tags: trunk) | |
| 16:06 | Do not run sync2.test as part of the "journaltest" permutation, as it uses "PRAGMA synchronous = off". (check-in: 285005a9bc user: dan tags: trunk) | |
| 15:29 | Ensure that a "--" prefix is added to sqlite3_trace_v2() output for nested SQL statements. (check-in: 673a7b67c4 user: drh tags: trunk) | |

| 20:56 | Merge trunk fixes for "x IN (?)" handling. (check-in: eca35871c3 user: drh tags: orderby-planning) | |
| 19:04 | Remove a testcase() that is now always true due to the "x IN (?)" optimization. Add an ALWAYS() around a conditional in the parser that cannot be false. (check-in: d5a1530bdc user: drh tags: trunk) | |
| 18:56 | Only use the direct-overflow-read optimization if all data from the overflow page in question is being read. (check-in: d8e1f75ddf user: dan tags: overflow-pgno-cache) | |
| 18:45 | Fix the EXPLAIN indenter in the command-line shell to correctly handle NextIfOpen and PrevIfOpen opcodes. (check-in: 01944c53f5 user: drh tags: trunk) | |
| 17:03 | The "x IN (?)" optimization in check-ins [2ff3b25f40] and [e68b427afb] is incorrect, as demonstrated by the in4-5.1 test case in this check-in. The "COLLATE binary" that was being added to the RHS of IN was overriding the implicit collating sequence of the LHS. This change defines the EP_Generic expression node property that blocks all affinity or collating sequence information in the expression subtree and adds that property to the expression taken from RHS of the IN operator. (check-in: 2ea4a9f75f user: drh tags: trunk) | |
| 15:14 | Fix harmless compiler warnings. (check-in: b1435f26b0 user: drh tags: trunk) | |
| 14:56 | Previous check-in is not quite correct. "x IN (?)" is not exactly the same as "x==?" do to collation and affinity issues. The correct converstion should be to "x==(+? COLLATE binary)". The current check-in fixes this problem and provides test cases. Ticket [e39d032577df69] (check-in: 2ff3b25f40 user: drh tags: trunk) | |
| 13:32 | • Edit [eae6dfbe5535f481|eae6dfbe55]: Mark "Closed". (artifact: 5d2bec0f82 user: drh) | |
| 13:31 | • Fixed ticket [e39d032577]: Assertion fault on a query containing "x IN (?)" plus 6 other changes (artifact: 8a7c5a08b3 user: drh) | |
| 13:26 | Convert expressions of the form "X IN (?)" with exactly one value on the RHS of the IN into equality tests: "X=?". Add test cases to verify that statements work correctly on this corner case. Fix for ticket [e39d032577df6942]. (check-in: e68b427afb user: drh tags: trunk) | |
| 12:36 | One possible fix for the [e39d032577d] problem it to replace the failing assert() with a testcase() as shown here. (Closed-Leaf check-in: eae6dfbe55 user: drh tags: tkt-e39d0325) | |
| 12:17 | Fix an unnecessarily obtuse use of a bitmask flag. (check-in: ca31408131 user: drh tags: trunk) | |
| 11:52 | • New ticket [e39d032577] Assertion fault on a query containing "x IN (?)". (artifact: c3311ddb99 user: drh) | |
| 09:42 | Add a test to ensure os_unix.c works with 64KiB OS pages. (Closed-Leaf check-in: e3d2be3ba4 user: dan tags: shm-mapping-fix) | |
| 08:59 | Add an experimental fix to avoid attempting to mmap memory from an offset that is not a multiple of the system page size on systems with page sizes larger than 32KB. (check-in: 6f3a5c24d2 user: dan tags: shm-mapping-fix) | |

| 13:15 | Rename the unused MEM2 static mutex to OPEN and reuse it to serialize access to the sqlite3BtreeOpen() routine to prevent a race condition on detection of sharable caches. Ticket #3735. (CVS 6363) (check-in: 19fa5a29b9 user: drh tags: trunk) | |
| 10:24 | Fix a problem in thread005.test cause errors on osx. (CVS 6362) (check-in: 56e6fca1a9 user: danielk1977 tags: trunk) | |
| 09:09 | Fix a problem in loadext.test causing an error on OSX. This is not a real problem, just a case of the test script expecting a slightly different error message than the one returned. (CVS 6361) (check-in: 18680989b5 user: danielk1977 tags: trunk) | |
