| 14:08 | Add an "|| CORRUPT_DB" term to an assert() that might be false if the database is corrupt. Also add a branch to have sqlite3PagerMovepage() return SQLITE_CORRUPT in that case. (check-in: b0d5cf40 user: drh tags: trunk) | |
|
2019-03-05
| ||
| 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: 3803e750 user: drh tags: trunk) | |

| 14:47 | New dbfuzz2 test cases added to test/fuzzdata7.db (check-in: 25975e1f 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: c1ac0070 user: drh tags: trunk) | |

2019-02-23
| ||
| 20:48 | Fix a couple of assert() statements in fts3 that can be false if the database is corrupt. (check-in: 84162af5 user: dan tags: trunk) | |
| 00:56 | Import from trunk the new fix to ticket [df46dfb631f75694] in which all ephemeral tables used as the RHS of an IN operator be index btrees and never table btrees so that they can always be reused. (check-in: 0e64ac12 user: drh tags: branch-3.27) | |
| 00:21 | Check-in [fa792714ae62fa98] is incorrect. Add a test case to refute it and also a fix to make it right. Then add an alternative fix to ticket [df46dfb631f75694] in which all ephemeral tables used as the RHS of an IN operator be index btrees and never table btrees so that they can always be reused. (check-in: d3915230 user: drh tags: trunk) | |
| 00:08 | Remove a testcase() macro which is now unreachable due to the contraction of the use of IN_INDEX_ROWID. (Closed-Leaf check-in: 90c5a17c user: drh tags: tkt-df46dfb631) | |
|
2019-02-22
| ||
| 23:29 | Make all ephemeral tables built to hold the RHS of an IN operator be index-btrees, never table-btrees, regardless of whether or not they are used as IN_INDEX_LOOP or IN_INDEX_MEMBERSHIP. That way, the same ephmerial table can be reused for both cases. (check-in: c2d50df8 user: drh tags: tkt-df46dfb631) | |
| 21:33 | Check-in [fa792714ae62fa980] is not a valid fix for ticket [df46dfb631f75694], as the new test case in this check-in demonstrates. The fix here causes test cases for the [df46dfb631f75694] bug to fail again, so this check-in is on a branch. A new fix is needed for [df46dfb631f75694]. (check-in: 0d456456 user: drh tags: tkt-df46dfb631) | |
| 19:24 | Internally, remove all references to a Window object that belongs to an expression in an ORDER BY clause if that expression is converted to an alias of a result-set expression. Fix for [4feb3159c6]. (check-in: 579b66ea user: dan tags: trunk) | |
| 17:44 | Merge latest trunk changes into this branch. (check-in: 001771af user: dan tags: reuse-schema) | |
| 16:18 | In sqlite3NestedParse() be sure to detect all SQLITE_NOMEM and SQLITE_TOOBIG errors and to distinguish between them. (check-in: 73056b31 user: drh tags: trunk) | |
| 15:42 | Modify sqlite3_str_finish() and sqlite3VMPrintf() so that they always return NULL on any OOM or SQLITE_LIMIT_LENGTH error. (check-in: e7144ffd user: drh tags: trunk) | |
|
2019-02-21
| ||
| 18:11 | Fix OOM handling in sqlite3NestedParse(). (Leaf check-in: e6e9dd5c user: dan tags: nested-parse-oom) | |
| 16:41 | Detect oversized strings in the OP_String opcode even if the P4 argument is originally UTF8 and has to be converted to UTF16 to match the database file and that conversion causes the string to become shorter and cross below SQLITE_LIMIT_LENGTH threshold. This might fix an OSSFuzz problem that we have been so far unable to reproduce. (check-in: c13d5639 user: drh tags: trunk) | |
|
2019-02-20
| ||
| 19:20 | Changes to the unix VFS that allegedly enable it to build of Fuchsia. We have no way of testing this. (check-in: be21a641 user: drh tags: trunk) | |
| 19:06 | Disable unix-specific features of dbfuzz2 when compiling on windows. (check-in: af84774d user: drh tags: trunk) | |
| 18:44 | Further test cases and fixes for SQLITE_OPEN_SHARED_SCHEMA. (check-in: ba0ab042 user: dan tags: reuse-schema) | |
| 18:13 | Avoid the use of function pointers in columnName(), as function pointers appear to be a source of consternation to LLVM. (check-in: c48f6f39 user: drh tags: trunk) | |
| 17:36 | Add test and fixes for SQLITE_OPEN_SHARED_SCHEMA mode. (check-in: 9a78d89c user: dan tags: reuse-schema) | |
| 13:55 | Progress handler improvements: (1) Invoke the callback after OP_Program opcodes (2) Invoke the callback multiple times in a row to catch up after a long run of no progress checks. (check-in: 0c5db18d user: drh tags: trunk) | |
| 13:23 | Merge the latest performance enhancements and fixes from trunk. (check-in: be71d1e2 user: drh tags: apple-osx) | |
| 13:14 | Increment the version number to 3.27.2. (check-in: a70d67d8 user: drh tags: branch-3.27) | |
| 13:12 | When an IN operator drives a query loop, mark it as "CODED" so that it will not be used afterwards for a (pointless) membership test. (check-in: 55e38d53 user: drh tags: branch-3.27) | |
| 12:52 | When an IN operator drives a query loop, mark it as "CODED" so that it will not be used afterwards for a (pointless) membership test. This is a better fix for ticket [df46dfb631f75694] than the previous fix that is now on a branch as it preserves the full optimization of check-in [e130319317e76119]. (check-in: fa792714 user: drh tags: trunk) | |
| 03:38 | Back off the optimization of check-in [e130319317e76119] slightly so that it only applies to IN operators that are used for membership tests. Proposed fix for ticket [df46dfb631f75694]. (Closed-Leaf check-in: b5f90bfe user: drh tags: tkt-df46dfb631) | |
