| 20:52 | Fixes to the UPDATE logic in Geopoly. check-in: 7c3cee0a user: drh tags: trunk | |
| 20:24 | Also free up the MEM_RowSet bit in the Mem.flags field and have RowSet objects be destroyed using Mem.xDel. This change results in faster code. check-in: f48e9feb user: drh tags: trunk | |
| 18:47 | Free up the MEM_Frame bit in Mem.flags object. Store VdbeFrame objects as MEM_Blob with a special Mem.xDel pointer instead. check-in: 62db5fd4 user: drh tags: trunk | |

|
2018-08-27
| ||
| 17:13 | Add support for the Geopoly extension to the R-Tree extension. This also involves adding the SQLITE_INDEX_CONSTRAINT_FUNCTION capability to the xFindFunction method of the sqlite3_module object, and to the sqlite3_index_info.aConstraint.op field in the xBestIndex implementation of virtual tables. check-in: 666133e3 user: drh tags: trunk | |

| 19:51 | Provide the two-argument geopoly_within(P1,P2) routine that determines if polygon P2 is contained within polygon P1. Make this function available to the query planner for optimized rtree lookups. Update the visual01.txt script to verify that the new functionality actually works. check-in: 6eb5d09b user: drh tags: rtree-geopoly | |

|
2018-08-24
| ||

| 20:10 | Fix a problem with renaming a column that occurs as an "excluded.colname" construction in an UPSERT that is part of a trigger program. check-in: bb2f7234 user: dan tags: alter-table-rename-column | |
| 19:04 | Set SQLITE_PTRSIZE to 4 when compiling with xlc on 32-bit AIX. check-in: d158e5b1 user: mistachkin tags: trunk | |
| 17:55 | After modifying and reparsing the schema as part of an ALTER TABLE RENAME COLUMN, check that no new schema errors have been introduced (e.g. ambiguous column names in views) before committing the operation. check-in: a0e06d2c user: dan tags: alter-table-rename-column | |
| 16:04 | Avoid incorrectly replacing tokens that refer to a column being renamed via an alias. For example, do not overwrite "xyz" when "a" is renamed in "CREATE VIEW v1 AS SELECT a AS xyz FROM tbl WHERE xyz=1" check-in: ad072a83 user: dan tags: alter-table-rename-column | |
|
2018-08-23
| ||
| 20:09 | Add the "atrc" test program to the Makefiles. Fix a typo in the instructions in the header comment of the atrc program. check-in: 2130a407 user: drh tags: alter-table-rename-column | |
| 19:32 | Fix harmless compiler warnings in the ALTER TABLE logic. Rephrase an error message to use active voice. check-in: a7dae59a user: drh tags: alter-table-rename-column | |
| 18:56 | Automatically detect when compiling for AArch64 on windows and set SQLITE_BYTEORDER to little-endian to avoid compile-time testing. check-in: ef6729be user: drh tags: trunk | |

| 18:08 | Allow an ALTER TABLE RENAME COLUMN to proceed even if the schema contains a virtual table for which the module is unavailable. check-in: 7b72b236 user: dan tags: edit-trigger-wrapper | |
| 17:18 | Ensure that CREATE VIEW, TRIGGER or INDEX statements can be edited by ALTER TABLE RENAME COLUMN even if they use collation-sequences or user-defined-functions that are not available. check-in: 540014ef user: dan tags: edit-trigger-wrapper | |
|
2018-08-16
| ||
| 19:49 | Further progress on updating trigger programs as part of ALTER TABLE RENAME COLUMN. check-in: 3f47222b user: dan tags: edit-trigger-wrapper | |

| 15:29 | Fix EXPLAIN QUERY PLAN so that it describes IN operators implemented using a ROWID lookup. check-in: 60045fbf user: drh tags: trunk | |
|
2018-08-15
| ||
| 20:28 | Have ALTER TABLE RENAME COLUMN edit trigger programs. Only partly working. check-in: e272dc2b user: dan tags: edit-trigger-wrapper | |

| 16:18 | Fix ALTER TABLE RENAME COLUMN in cases where the column being renamed is an IPK declared with a separate PRIMARY KEY clause - "CREATE TABLE x(y INTEGER, PRIMARY KEY(y))". check-in: 32ca8418 user: dan tags: alter-table-rename-column | |
| 15:12 | Fix UPSERT so that it checks the target-constraint first and fires the DO UPDATE if that constraint is violated regardless of whether or not other constraints are in violation. This aligns SQLite behavior with what PostgreSQL does. Fix for ticket [908f001483982c43cdb476dfb590a1a]. check-in: 529fb55e user: drh tags: trunk | |

| 22:50 | Stop requiring the global VFS mutex to access the unixInodeInfo.pUnused field. The unixInodeInfo mutex is sufficient. check-in: e3ea43da user: drh tags: trunk | |
| 20:46 | Take extra precautions to ensure access to unixInodeInfo.pUnused is protected by all necessary mutexes. check-in: 8b1e0010 user: drh tags: trunk | |

| 12:58 | Fix a heap-corruption causing race condition in os_unix.c that could occur when one thread wal opening a database file while another is unlocking the same file. Edit: Let's go in a slightly different direction with this fix. Closed-Leaf check-in: 2447e0fd user: dan tags: unix-lock-fix-attempt | |
| 11:32 | Fix an incorrect comment on the unix-nolock VFS object. No functional code changes. check-in: 90f7c193 user: drh tags: trunk | |
|
2018-08-11
| ||
| 20:46 | Add the "atrc" test program. "Atrc" is short for "ALTER TABLE RENAME COLUMN". See the header comment on the program itself for further information. check-in: ed64a55a user: drh tags: alter-table-rename-column | |
| 20:38 | If the new column name in an ALTER TABLE RENAME COLUMN statement is quoted, then also use quotes for the column name in the edited SQL statements. check-in: ca5184a2 user: dan tags: alter-table-rename-column | |

|
2018-08-09
| ||
| 21:45 | Fix the isLikeOrGlob() routine in the WHERE clause processing logic so that it avoids signed/unsigned character comparisons, as that can lead to an incorrect answer if the ESCAPE clause is an invalid UTF8 string. Problem found by OSSFuzz. check-in: 4195a3f8 user: drh tags: trunk | |
| 20:47 | Experimental implementation of ALTER TABLE ... RENAME COLUMN. Still buggy. check-in: fa0fc01e user: dan tags: alter-table-rename-column | |
| 18:36 | When a column must be a constant due to WHERE clause and the value of that column is being coded as a constant, make sure the affinity is correct. check-in: 7404ea83 user: drh tags: trunk | |

2018-08-06
| ||
| 17:12 | Allow sqlite3_snapshot_open() to be called to change the snapshot after a read transaction is already open on database. Closed-Leaf check-in: 051ac015 user: dan tags: exp-snapshot-open | |
| 02:08 | Enhance the edit() function so that it converts text from \r\n back into \n only if the original unedited copy contained no \r\n values. check-in: 20c995d3 user: drh tags: trunk | |
| 01:39 | Add the --info option to the fuzzcheck test utility. check-in: 1caaaaa7 user: drh tags: trunk | |

| 20:30 | Remove the column-cache from the code generator. The column-cache has been a persistent source of bugs for years and with recent improvements in the performance of OP_Column, it no longer provides a benefit. After the column cache is removed, the binary is almost 2KB smaller and the speed-check.sh performance test is over 3 million cycles faster. check-in: cdff3af7 user: drh tags: trunk | |
| 20:12 | Remove a testcase() that is no longer reachable without the column cache. Provide an assert() to help prove that the testcase is no longer reachable. Closed-Leaf check-in: a500893b user: drh tags: omit-column-cache | |
| 17:15 | Fix comments that were made obsolete by the removal of the column cache. check-in: 2041231d user: drh tags: omit-column-cache | |
| 16:54 | Remove more column-cache residue: The OP_SetColTab and OP_VerifyColTab opcodes and the associated SQLITE_DEBUG_COLUMNCACHE logic. check-in: 80236e81 user: drh tags: omit-column-cache | |
| 15:53 | Further logic simplifications that flow out of the omission of the column cache. check-in: 7d9072b0 user: drh tags: omit-column-cache | |
| 15:28 | Add test cases for the constant expression fix of the previous check-in. check-in: 95db5bd9 user: drh tags: trunk | |
| 15:16 | Ensure that all expressions that are to be evaluated once at the start of a prepared statement (the Parse.pConstExpr expressions) pass the sqlite3ExprIsConstantNotJoin() test. It is not sufficient to pass just the sqlite3ExprIsConstant() test as that would allow through column references that are bound to constants by the WHERE clause in the constant propagation optimization. This fixes a problem discovered by OSSFuzz. check-in: 8bc7f84c user: drh tags: trunk | |
| 14:30 | Remove additional traces of the column cache. check-in: db6052e9 user: drh tags: omit-column-cache | |
|
2018-08-03
| ||
| 23:04 | Completely remove the column cache logic, which has been a persistent source of bugs for many years. Due to recent enhancements to the performance of the OP_Column opcode, removing the column cache actually makes speed-check.sh run faster. Removing the column cache also saves about 1,800 bytes of code space. check-in: 3f5f60cd user: drh tags: omit-column-cache | |
| 20:19 | Fix the handling of sub-queries with LIMIT clauses by the optimization activated by compile-time symbol SQLITE_COUNTOFVIEW_OPTIMIZATION. check-in: 21235d9a user: dan tags: trunk | |
| 15:58 | Fix the OP_SeekRowid opcode so that it has no type-change side-effects on the key register in P3. This fixes an obcure problem that arises when doing equi-joins between a table with a TEXT column against another table with an INTEGER PRIMARY KEY. The original problem was discovered when OSSFuzz created such a query and hit an assert() in OP_VerifyTabCol that was specifically designed to catch these kinds of errors at run-time. Test cases for this fix are in TH3. check-in: fa94b49e user: drh tags: trunk | |
| 13:56 | Improve "PRAGMA vdbe_trace=ON" to always show the key values for the OP_IdxGT and related opcodes. check-in: 0f881955 user: drh tags: trunk | |
|

| 18:56 | In the command-line shell, always exit if realloc() fails. check-in: e390023c user: drh tags: trunk | |
|
2018-07-28
| ||
| 21:01 | Add a small cost penalty to sorting to bias the query planner in favor of plans that do not require a final sorting pass. check-in: 85b9beb4 user: drh tags: trunk | |
| 16:24 | Do not allow a column reference that is converted into a constant by the WHERE-clause constant propagation optimization to be moved to the init-time constant expression list, as the table reference will not work there. This fixes a problem found by OSSFuzz. check-in: d30b2a94 user: drh tags: trunk | |
