| ||
| 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 | |
| 00:21 | 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
| ||
| 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 | |
| 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 | |
|

| 20:29 | Enhance the xBestIndex method on delta_parse() to return SQLITE_CONSTRAINT if no delta argument is supplied. check-in: f16d127c user: drh tags: trunk | |
| 20:19 | Add the delta_parse(DELTA) table-valued function to the fossildelta extension. check-in: d91fcc26 user: drh tags: trunk | |

| 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: 12517d1b user: drh tags: trunk | |
| 16:42 | Fix an assert() that might not be true if the database file is corrupt. check-in: f2d400db user: drh tags: trunk | |
| 13:51 | New assert() to verify the TF_HasprimaryKey flag. check-in: 0abace8a user: drh tags: trunk | |
| 13:08 | Always use the symbolic name SQLITE_IDXTYPE_PRIMARYKEY rather than a hard-coded magic number 2. check-in: 55d43adc user: drh tags: trunk | |

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: cb236cb9 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: ecf6251e 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: 03c4f003 user: dan tags: reuse-schema | |
|
2019-02-14
| ||
| 21:04 | Fix SQLITE_DBSTATUS_SCHEMA_USED so that it works with SQLITE_OPEN_SHARED_SCHEMA connections. check-in: d43b3c05 user: dan tags: reuse-schema | |
| 18:38 | Change the name of the SQLITE_OPEN_REUSE_SCHEMA flag to SQLITE_OPEN_SHARED_SCHEMA. check-in: 7257fcc8 user: dan tags: reuse-schema | |

| 15:56 | Merge latest trunk into this branch. check-in: 577d1638 user: dan tags: reuse-schema | |
| 15:47 | Add missing comments and fix other code issues in the new functions in callback.c. check-in: 441cabb6 user: dan tags: reuse-schema | |
| 15:27 | Improved oversized cell detection when updating ptrmap pages in balance_nonroot(). check-in: aa61435a user: drh tags: trunk | |
|
2019-02-13
| ||
| 19:17 | Fix for sqlite3_table_column_metadata() on REUSE_SCHEMA databases. check-in: 53220ad7 user: dan tags: reuse-schema | |
| 18:29 | Avoid crashing after parsing a corrupt schema with a REUSE_SCHEMA connection. check-in: b102148e 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: 167b91df 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: 68cce272 user: drh tags: trunk | |

| 22:33 | Fix a page-cache reference leak in the btree balancer when there is a corrupt database. check-in: 92858991 user: drh tags: deferred-free-space | |
| 21:06 | Defer computing the MemPage.nFree value of an in-memory btree page until it is actually needed, since for many pages it is never needed. This checkin works sufficiently to prove the concept, but still has issues with exception handling. check-in: 1d43ee40 user: drh tags: deferred-free-space | |

| 15:59 | Change the sqlite3VdbeMemGrow() routine so that it no longer guarantees a minimum size of 32 bytes. That minimum is no longer required, and without the extra check for the minimum size, the routine runs faster. check-in: 5c499da8 user: drh tags: trunk | |
| 14:55 | Give the sqlite3 object a pointer to the current Parse so that if an OOM occurs, it can automatically set the Parse.rc value to SQLITE_NOMEM. This avoids a frequent extra test of db.mallocFailed in the innermost parser loop. check-in: 5c663804 user: drh tags: trunk | |
| 04:15 | Do not do the optimization that attempts to pull expression values from an index on that expression when processing a multi-index OR (see check-in [a47efb7c8520a0111]) because the expression transformations that are applied become invalid when the processing moves off of the current index and on to the next index.
