| 17:54 | Where possible, avoid loading all schemas into memory for PRAGMA statements. (check-in: 64f97530ad user: dan tags: reuse-schema) | |
| 16:06 | Version 3.27.2 (check-in: bd49a8271d user: drh tags: release, branch-3.27, version-3.27.2) | |
| 15:55 | 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. (check-in: a21ffcd817 user: drh tags: branch-3.27) | |
| 15:43 | This was originally intended to be the 3.27.2 release, but then I realized that I left out an important patch. (Closed-Leaf check-in: 6c5e5e2ee0 user: drh tags: mistake) | |
| 14:52 | Update comments on the fossildelta extension. No changes to code. (check-in: 9da4fb59b2 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: 84162af521 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: 0e64ac122a 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: d3915230e3 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: 90c5a17cd5 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: c2d50df8fd 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: 0d456456da 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: 579b66eaa0 user: dan tags: trunk) | |
| 17:44 | Merge latest trunk changes into this branch. (check-in: 001771afd0 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: 73056b314b 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: e7144ffd21 user: drh tags: trunk) | |
|
2019-02-21
| ||
| 18:11 | Fix OOM handling in sqlite3NestedParse(). (Leaf check-in: e6e9dd5c17 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: c13d563925 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: be21a6416d user: drh tags: trunk) | |
| 19:06 | Disable unix-specific features of dbfuzz2 when compiling on windows. (check-in: af84774d1e user: drh tags: trunk) | |
| 18:44 | Further test cases and fixes for SQLITE_OPEN_SHARED_SCHEMA. (check-in: ba0ab042f4 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: c48f6f39c5 user: drh tags: trunk) | |
| 17:36 | Add test and fixes for SQLITE_OPEN_SHARED_SCHEMA mode. (check-in: 9a78d89c84 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: 0c5db18d79 user: drh tags: trunk) | |
| 13:23 | Merge the latest performance enhancements and fixes from trunk. (check-in: be71d1e24c user: drh tags: apple-osx) | |
| 13:14 | Increment the version number to 3.27.2. (check-in: a70d67d8af 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: 55e38d53ad 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: fa792714ae 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: b5f90bfe62 user: drh tags: tkt-df46dfb631) | |

| 20:19 | Add the delta_parse(DELTA) table-valued function to the fossildelta extension. (check-in: d91fcc267b user: drh tags: trunk) | |

| 18:00 | Improve error messages caused by corrupt database schemas in OPEN_SHARED_SCHEMA mode. (check-in: 8ac75b8a88 user: dan tags: reuse-schema) | |
| 17:45 | Fix a potential memory leak in RBU if the rbu_fossil_delta() SQL function is misused. Misuse never happens in a working RBU system, so this is not a particularly important fix. (check-in: 12517d1b15 user: drh tags: trunk) | |
| 16:42 | Fix an assert() that might not be true if the database file is corrupt. (check-in: f2d400db4d user: drh tags: trunk) | |

|
2019-02-18
| ||
| 18:16 | Ensure that creating temp schema items does not cause an OPEN_SHARABLE_SCHEMA connection to load all schemas into memory. (check-in: 88cbf54eee user: dan tags: reuse-schema) | |

|
2019-02-15
| ||
| 19:36 | Enhance the virtual table in test_schemapool.c so that it can be used to check that SHARED_SCHEMA connections are not allocating and freeing schemas when they should not be. (check-in: cb236cb985 user: dan tags: reuse-schema) | |
| 19:00 | Fix a problem with eponymous virtual tables and SHARED_SCHEMA databases. Also, after preparing statements that require all database schemas (REINDEX, ANALYZE, CREATE, DROP and some PRAGMA statements), do not allow the database connection to return more than one schema to each schema-pool. (check-in: ecf6251ec0 user: dan tags: reuse-schema) | |
| 11:54 | Revert the rearrangement of VDBE code in [219b39e14] so that vdbe.c matches trunk. Since the new call to sqlite3Init() in OP_ParseSchema was removed, the rearrangement no longer provides any performance advantage. (check-in: 03c4f00317 user: dan tags: reuse-schema) | |
|
2019-02-14

| 15:56 | Merge latest trunk into this branch. (check-in: 577d163836 user: dan tags: reuse-schema) | |
| 15:47 | Add missing comments and fix other code issues in the new functions in callback.c. (check-in: 441cabb62f user: dan tags: reuse-schema) | |

| 13:48 | Performance optimization in the VDBE, and a fix for a harmless compiler warning. (Closed-Leaf check-in: e002666ac7 user: drh tags: reuse-schema-vdbe-opt) | |
| 08:40 | Fix a problem with OPEN_REUSE_SCHEMA connections reloading the temp schema. (check-in: 7c2ec2d4cf user: dan tags: reuse-schema) | |

| 22:58 | Ensure that the nProgressLimit variable is always initialized in sqlite3VdbeExec(), even if the routine jumps to its exit processing early. (check-in: 167b91df77 user: drh tags: trunk) | |
| 21:04 | Enhancement the progress callback mechanism so that the progress callback is always invoked at least once at the end of a prepared statement if the opcode count has been exceeded. This makes the progress callback more effective at limiting run times. This check-in also includes and unrelated performance enhancement to OP_Column. (check-in: 68cce272e7 user: drh tags: trunk) | |
