| 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) | |
| 19:00 | Merge trunk change [895bd20b29] into this branch. (Actually check-in date was 2020-05-18) (check-in: 507f972e91 user: dan tags: reuse-schema) | |
| 18:04 | Report an error if the main, or any other, database encoding is modified by an external process (perhaps using the backup API) after the db has been opened. (check-in: 895bd20b29 user: dan tags: trunk) | |
| 16:37 | • New ticket [fa146dcfe6] Unexpected result for MIN on string that contains a null character. (artifact: 33ec640208 user: mrigger) | |
| 16:30 | Merge trunk enhancements into the reuse-schema branch. (Actual check-in date is 2020-05-18) (check-in: 9d068e1ef0 user: drh tags: reuse-schema) | |
| 16:26 | • Fixed ticket [1b8d726456]: MAX yields unexpected result for UTF-16 plus 6 other changes (artifact: bf4e521e96 user: drh) | |
| 16:13 | Change the sqlite3.pDfltColl (the default collating sequence for the database connection) so that it is the collating sequence appropriate for the database encoding, not the UTF8 collating sequence. This helps to ensure that the database encoding collation is always used, even for expressions that do not have an defined collating sequence. Ticket [1b8d7264567eb6fc]. (check-in: 4a5851893c user: drh tags: trunk) | |
| 14:19 | When printing the OP_CollSeq opcode for EXPLAIN listings, include the text encoding with the name of the collating sequence. (check-in: eb5c1b77d1 user: drh tags: trunk) | |

| 23:49 | Fix a potential 32-bit integer overflow in the "showdb" utility program when it is trying to interpret a corrupt database file. (check-in: 3803e75038 user: drh tags: trunk) | |
| 19:29 | Extend windowCodeStep() to handle any ROWS PRECEDING/FOLLOWING frame specification. (check-in: af0ea13635 user: dan tags: window-functions) | |
| 16:53 | Add a script to tool/ that will extract the sqlite3.h header file from an sqlite3.c amalgamation. (check-in: 38d2e510cd user: drh tags: trunk) | |
| 14:47 | New dbfuzz2 test cases added to test/fuzzdata7.db (check-in: 25975e1fb2 user: drh tags: trunk) | |
| 14:39 | If the initial byte of a record is a large value, then always used the generalized record comparison routine sqlite3VdbeRecordCompare() rather than one of the specialized versions that are optimized for shorter records. (check-in: c1ac00706b user: drh tags: trunk) | |

2018-03-05
| ||
| 23:23 | Fix walIteratorInit() so that it always leaves the iterator as a NULL pointer if an OOM occurs. This fixes an assertion fault introduced by check-in [044b0b65e716bff]. (check-in: e5ce256aa1 user: drh tags: trunk) | |
| 21:19 | Merge the session fix from trunk. (check-in: 6274cf1f39 user: drh tags: memdb) | |
| 21:17 | Fix another crash in the sessions module triggered by malformed input. (check-in: 7e70c9b86a user: dan tags: trunk) | |
| 20:21 | Improved command-line help for the -A option on the CLI. (check-in: d937ac181c user: drh tags: trunk) | |
| 20:20 | A new way of doing archive commands on the command-line for the CLI. The -A option means that everything that follows is a ".archive" command, including any suffix on the -A option. (check-in: 9d8081fabc user: drh tags: trunk) | |
| 19:34 | In the CLI, add a new command-line option "--archive" (also "--ar") that passes all subsequent arguments to the ".archive" command. (check-in: a5c4d30af1 user: drh tags: trunk) | |
| 18:20 | Merge session fixes from trunk. (check-in: 99c02aeecf user: drh tags: memdb) | |

| 21:32 | Fix a problem in the previous commit affecting queries with three or more tables joined together to the right of a LEFT or CROSS JOIN operator. (check-in: d8d89d69a4 user: dan tags: trunk) | |
| 21:11 | • Edit [fd7cd0609381a856|fd7cd06093]: Mark "Closed". (artifact: d53d262ec6 user: drh) | |
| 21:07 | Change the way SQLite invokes the xBestIndex method of virtual tables so that N-way joins involving virtual tables work as expected. (check-in: 195444380b user: dan tags: trunk) | |
| 20:28 | Adjust the cost estimates for RTREE such that the expected number of rows and expected cost is halved for each additional constraint. (Closed-Leaf check-in: fd7cd06093 user: drh tags: xbestindex-fix) | |
| 17:29 | Change the way SQLite invokes the xBestIndex method of virtual tables so that N-way joins involving virtual tables work as expected. (check-in: ffc65968ed user: dan tags: xbestindex-fix) | |
| 15:35 | Remove the unused journal.c source file (its function have been subsumed into memjournal.c). Refactor some of the names in memjournal.c. No functional changes. (check-in: 5f2a262d3f user: drh tags: trunk) | |
| 15:03 | Work around (incorrect) ASAN warnings in memjournal.c. (check-in: 4de09777da user: drh tags: trunk) | |
| 14:19 | Fix an integer size mismatch problem in test_bestindex.c (check-in: 2e35eb6b74 user: drh tags: trunk) | |
| 14:00 | Fix an incorrect #ifdef on sqlite3LogEstToInt(). (check-in: dca7b23354 user: drh tags: trunk) | |

| 21:41 | Simplifications to the overflow-free multiplier. Also remove some commented-out code that was left in that subroutine by mistake on the previous check-in. (check-in: 55fc25fdab user: drh tags: trunk) | |
| 20:59 | Fix all known instances of signed-integer overflow. Within SQL expressions, integer overflow now forces coercion to floating point. The shift operators work with any integer right-hand operand with negative values reversing the direction of the shift. (check-in: abf2139412 user: drh tags: trunk) | |
| 13:54 | Fix an instance of signed arithmetic overflow and an one bit-shift overflow. Mark six other signed arithmetic overflow locations that need fixing. (check-in: 04abab71ec user: drh tags: trunk) | |
