2018-11-23
| ||
| 13:21 | Make the winTruncate() method of the windows VFS be a no-op if there are outstanding references to the memory-mapped pages. Otherwise, memory might be deleted out from under those references when the file is remapped during the truncate operation. (Leaf check-in: 8576ccb479 user: drh tags: branch-3.25) | |

| 20:04 | When a table is renamed using "ALTER TABLE RENAME TO", update any REFERENCES clauses that refer to the table, unless "PRAGMA legacy_alter_table" is true and "PRAGMA foreign_keys" is set to false (i.e. so that when "PRAGMA legacy_alter_table" is set behaviour is still compatible with versions 3.24 and earlier). (check-in: ae9638e9c0 user: dan tags: trunk) | |
| 18:44 | Merge latest trunk changes with this branch. (check-in: ae88f8e1ff user: dan tags: reuse-schema) | |
| 14:17 | Fix for ticket [787fa716be3a7f650cac] (check-in: 531eca6104 user: drh tags: trunk) | |
| 00:02 | Disable the use of coroutines for subqueries within a query that is the RHS of an IN operator, as the IN operator might be evaluated more than once. Possible fix for [787fa716be3a7f65], unless we can come up with something better. Later: Counter-example found. (Closed-Leaf check-in: 8d663bfaaa user: drh tags: tkt787fa716-deadend) | |

| 17:52 | Update the "changesetfuzz" program to work with patchsets as well as changesets. (check-in: 75b00fbe88 user: dan tags: changesetfuzz) | |
| 16:46 | Performance improvement in subroutine that decides whether or not a table is read-only. (check-in: 6e4968b005 user: drh tags: read-only-shadow) | |
| 16:12 | Merge the onefile permutation fix from trunk. (check-in: e543bff87d user: drh tags: read-only-shadow) | |

| 11:56 | Partially revert [3e1a2f661], as some test scripts require separate $presql and $dbconfig variables. (check-in: cbf85284be user: dan tags: trunk) | |
| 02:17 | Add the SQLITE_DEFAULT_DEFENSIVE compile-time option. Fix up test cases so that they work with DEFENSIVE enabled. (check-in: 3212733cb6 user: drh tags: read-only-shadow) | |
|
2018-11-06
| ||
| 20:08 | Update the changesetfuzz program to fuzz changeset schemas as well as data. (check-in: 141a93c843 user: dan tags: changesetfuzz) | |
| 19:26 | Enable DEFENSIVE mode by default for tests. This requires lots of case of turning DEFENSIVE off in order to dodgy things to the database for testing purposes. No all of those cases are yet handled, so "make test" does not run to completion. (check-in: a1d6c6712c user: drh tags: read-only-shadow) | |
| 15:57 | Turn on defensive mode for running test scripts. Does not yet work. (check-in: 1c1d24edbb user: drh tags: read-only-shadow) | |
| 14:03 | Only allow shadow table to be written from within a recursive SQL call. Omit the SQLITE_PREPARE_SHADOW flag. Some tests are failing because the tests depend on being able to write to shadow tables. (check-in: d890c65825 user: drh tags: read-only-shadow) | |
| 13:37 | Add enforcement of read-only on shadow tables. This does not currently work since some virtual tables are attempting to update shadow tables using sqlite3_exec(). (check-in: f79b47c985 user: drh tags: read-only-shadow) | |
|
2018-11-05
| ||
| 23:01 | Initial code to make shadow tables read-only to ordinary SQL. The now xShadowName method is added to the sqlite3_module object and is used to identify potential shadow tables. The SQLITE_PREPARE_SHADOW argument to sqlite3_prepare_v3() is defined. It is designed to permit writing to shadow tables, but is currently an unused placeholder. (check-in: 31942b3dd3 user: drh tags: read-only-shadow) | |

| 13:35 | Fix a assert() in the query planner that can arise when doing row-value operations on a PRIMARY KEY that contains duplicate columns. Ticket [1a84668dcfdebaf12415d]. (check-in: 1309c84ad3 user: drh tags: branch-3.25) | |
| 07:53 | Disable the IS NOT NULL optimization when the IS NOT NULL operator is part of the ON clause of a LEFT JOIN. Fix for ticket [65eb38f6e46de8c75e188a17ec]. (check-in: af39661e60 user: drh tags: trunk) | |
|
2018-11-03

| 16:51 | Add extra defenses against strategically corrupt databases to fts3/4. (check-in: d44318f590 user: dan tags: trunk) | |
| 16:09 | Add the SQLITE_DBCONFIG_DEFENSIVE flag. (check-in: af3f29d493 user: drh tags: dbconfig-defensive) | |
| 13:11 | Fix a assert() in the query planner that can arise when doing row-value operations on a PRIMARY KEY that contains duplicate columns. Ticket [1a84668dcfdebaf12415d]. (check-in: dcb8c73594 user: drh tags: trunk) | |
|
2018-11-02
| ||
| 17:38 | Enhance triggers so that they can use table-valued-functions that exist in schemas outside of the schema in which the trigger is defined. (check-in: 1fa74930ab user: drh tags: trunk) | |
|
2018-10-31
| ||
| 20:52 | Deploy the sqlite3Strlen30NN() function (argument guaranteed to be non-NULL) for a small performance improvement. (check-in: 4a6ad5190b user: drh tags: trunk) | |
| 19:01 | Add support for the SQLITE_PREPARE_NORMALIZED flag and the sqlite3_normalized_sql() when compiling with SQLITE_ENABLE_NORMALIZE. Also remove unnecessary whitespace from Makefiles. (check-in: 790ea39a65 user: drh tags: trunk) | |
| 18:24 | Tweaks to the test_intarray documentation and tests. (check-in: 7107f0dacf user: drh tags: trunk) | |
| 01:26 | Merge fixes from trunk, especially rebustness against corrupt database files. (check-in: 4b370c74ae user: drh tags: apple-osx) | |
| 01:12 | Merge fuzz test cases computed by dbfuzz2. (check-in: e0d30c1862 user: drh tags: trunk) | |
| 01:04 | Improved corrupt database detection in the relocatePage() routine of the b-tree module. (check-in: d57873337a user: drh tags: trunk) | |
|
2018-10-30
| ||
| 23:45 | Add new fuzzer cases generated by dbfuzz2. (Closed-Leaf check-in: 79fdad8b42 user: drh tags: dbfuzz2-cases) | |
| 19:14 | Update comments in sqlite3session.c to describe the format of "rebase blobs", as well as changesets and patchsets. (check-in: bf93f7b56b user: dan tags: trunk) | |
| 16:25 | Split the SQLITE_WriteSchema flag in two flags, WriteSchema and SQLITE_NoSchemaError. Set only WriteSchema on a VACUUM to avoid problems when trying to vacuum a corrupt database. With this change, the size of the flags field on sqlite3 must grow from 32 to 64 bytes. (check-in: 4f9878107a user: drh tags: trunk) | |
| 15:31 | Modify the CLI so that the --deserialize option is only available if it is compiled with SQLITE_ENABLE_DESERIALIZE. DESERIALIZE is now off by default for the main.mk makefile, but on for Makefile.in and Makefile.msc. (check-in: 90b2a684f7 user: drh tags: trunk) | |
| 15:20 | Improvements to the -fsanitize=fuzzer based database file fuzzer. (Cherrypick from the rubust-against-damaged-db branch.) (check-in: 3cc01a0eaf user: drh tags: trunk) | |
| 14:36 | In the CLI, when opening a file that begins with the normal SQLite prefix, open the file as a normal database even if it has a ZIP for AppendVFS record at the end. (check-in: 7989bbda70 user: drh tags: trunk) | |
| 13:19 | Enable sqlite3_deserialize() in the CLI. The --deserialize option associated with opening a new database cause the database file to be read into memory and accessed using the sqlite3_deserialize() API. This simplifies running tests on a database without risk of modifying the file on disk. (check-in: 5e0129ee9a user: drh tags: trunk) | |
| 00:06 | Improvements to the -fsanitize=fuzzer based database file fuzzer. (Closed-Leaf check-in: 585c94db09 user: drh tags: robust-against-damaged-db) | |
| 00:06 | In the VACUUM command, defer setting writable_schema until after it has been determined that the schema is not corrupt. (check-in: 3afec26014 user: drh tags: robust-against-damaged-db) | |

| 16:02 | Add an entry in Makefile.in to build dbfuzz2 using clang-6.0 with -fsanitize=fuzzer,undefined. (check-in: a4a083ed8c user: drh tags: trunk) | |
| 00:47 | Initial code for a fuzzing tool on database file that works with the -fsanitize=fuzzer option of clang. (check-in: 90d12094d3 user: drh tags: trunk) | |
|
2018-10-26
| ||
| 17:05 | Add the sqlite3session_config() interface. For configuring global parameters belonging to the sessions module. (check-in: 1e69f3ff05 user: dan tags: trunk) | |
| 15:36 | Prevent an == constraint specified using the table-valued-function argument syntax from being used to optimize any scan not related to the virtual table for which it was specified as an argument. (check-in: 4d46685f28 user: dan tags: trunk) | |
|
2018-10-25
| ||
| 16:58 | Merge bug fixes from trunk. (check-in: 1e973f65e8 user: drh tags: apple-osx) | |

| 14:15 | In the WHERE-constraint propagation optimization, if there are duplicate constraint, make sure only one of them propagates. Proposed fix for ticket [cf5ed20fc8621b165]. (check-in: 5d5b596f15 user: drh tags: trunk) | |
|
2018-10-24

|
2018-10-23
| ||
| 13:48 | Fix a problem with using window functions in compound (UNION, INTERSECT etc.) queries. (check-in: 059ff53a46 user: dan tags: trunk) | |
|
2018-10-20
| ||
| 13:48 | Add the sqlite3changeset_start_v2() - a new version of _start() that accepts a flags parameter - and a streaming equivalent to the sessions module. Also add the SQLITE_CHANGESETSTART_INVERT flag, used with start_v2() to invert a changeset while iterating through it. (check-in: cbedcb9aae user: dan tags: trunk) | |
|
2018-10-18
| ||
| 15:17 | Take steps to avoid a potential integer overflow in sessionBufferGrow(). (check-in: f7affa2e70 user: dan tags: trunk) | |

| 13:57 | Merge enhancements from trunk. (check-in: 9e10d88bcb user: drh tags: apple-osx) | |
| 13:51 | On the first connection to a WAL-mode database that was not cleanly shut down and contains a left-over -shm file, truncate the -shm file to 3 bytes instead of to 0 bytes. Avoiding a truncation to 0 means that system monitoring tools can better detect if a process illegitimately tries to truncate a -shm file. Such a rogue process might think it is being helpful by cleaning up old files, but there is a race condition that can cause damage to the database. (check-in: 90cf32cde0 user: drh tags: trunk) | |
| 10:37 | In the CLI, fix a file descriptor leak following OOM and a missing va_end() call. (check-in: ec36d15a9e user: drh tags: trunk) | |

| 14:38 | Fix the ".help -all" option in the command-line shell. (check-in: aac8f1dff0 user: drh tags: trunk) | |
| 14:33 | Ensure each ALTER TABLE statement makes just a single SQLITE_ALTER_TABLE call to the authorizer function. (Leaf check-in: dac285474a user: dan tags: alter-auth-callbacks) | |
| 13:46 | Add test cases and assert() statements to ensure that the authorizer is being called as expected from within ALTER TABLE. (check-in: ff10d2c7de user: dan tags: trunk) | |
|
2018-10-05
| ||
| 20:09 | When the left-hand side of a WHERE clause contraint is a UNIQUE column, and that term of the WHERE clause is not used for indexing, assume that the term reduces the number of output rows by half.

|
2018-10-04
| ||
| 18:17 | The 0x8000 optimization flag associated with SQLITE_TESTCTRL_OPTIMIZATIONS causes a large penalty (200) to be added to all sorting costs, which encourages the query planner avoid using the sorter. This flag can be used in experiments to help come up with a more accurate estimate of the true cost of sorting. (Leaf check-in: 857a1b01df user: drh tags: query-planner-debug) | |

2018-10-01
| ||
| 21:41 | Add the "PRAGMA table_xinfo" command that works like table_info but also shows hidden columns in virtual tables and adds the "hidden" boolean column. (check-in: defa0515b8 user: drh tags: trunk) | |

| 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: 051ac01520 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: 20c995d3f0 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: cdff3af7be 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: a500893b6f user: drh tags: omit-column-cache) | |
| 17:15 | Fix comments that were made obsolete by the removal of the column cache. (check-in: 2041231d56 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: 80236e81ce user: drh tags: omit-column-cache) | |
| 15:53 | Further logic simplifications that flow out of the omission of the column cache. (check-in: 7d9072b027 user: drh tags: omit-column-cache) | |

| 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: 8bc7f84c39 user: drh tags: trunk) | |

| 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: 3f5f60cd75 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: 21235d9a41 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: fa94b49e02 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: 85b9beb460 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: d30b2a9473 user: drh tags: trunk) | |

| 14:34 | Improved debugging output when the ".selecttrace" option is used in the shell. (check-in: fcb88dd6b0 user: drh tags: trunk) | |
| 13:37 | An early attempt at refactoring Expr (Closed-Leaf check-in: fc90a53de7 user: drh tags: expr-simplify-branch1) | |
| 01:30 | Add assert() statements to sqlite3ExprDelete() that prove various symmetry properties of the Expr object that might be exploited to make the Expr object smaller and faster. (check-in: 81f25d5c84 user: drh tags: expr-simplify) | |
|

| 23:33 | Improvements to the parser to increase coverage. Fix the parser so that at least one expresssion is required after PARTITION BY and within the list of expressions on VALUES(). (check-in: 02204f8b24 user: drh tags: trunk) | |
| 22:55 | When doing a DROP VIEW do not try to delete entries from the sqlite_stat1 table as there are none. (check-in: 7efdba2bbc user: drh tags: trunk) | |
| 22:14 | Minor grammar changes that help the parser run faster by reducing the number of NUL rule reductions. (check-in: cfd1b00592 user: drh tags: trunk) | |
| 20:45 | Enhance Makefile for MSVC to support building the shell tool without using the amalgamation. (check-in: 3d815d83a6 user: mistachkin tags: trunk) | |
| 20:37 | The WHERE-clause constant propagation optimization attempts to use transitive laws to replace column values with constants in the WHERE clause in order to help to query planner make more aggressive optimizations. (check-in: f4229707ac user: drh tags: trunk) | |
| 20:01 | Reduce the performance cost of the constant propagation optimization to less than 200,000 cycles. (Closed-Leaf check-in: 865249de68 user: drh tags: propagate-const-opt) | |
| 18:19 | Performance improvement to sqlite3ExprCollSeq(). With this change, the performance of speed-check.sh is within 400,000 cycles of trunk. (check-in: a5f86f49b7 user: drh tags: propagate-const-opt) | |
| 18:12 | Faster implementation of sqlite3IsBinary(). (check-in: be05d0db09 user: drh tags: propagate-const-opt) | |
| 17:51 | Only run the constant propagation optimization on joins since that is the only scenario where it is useful. This saves prepare time for the common case of a simple query. (check-in: 598d608359 user: drh tags: propagate-const-opt) | |
| 16:57 | Constant propagation is now restricted to just the WHERE clause. The mechanism is changed to take affinity and collation into account. This seems to give correct answers. But the search for constant propagation costs 4 million cycles in the speed test. (check-in: 82c67efb72 user: drh tags: propagate-const-opt) | |
|

| 23:54 | Add a test case demonstrating the collation problem with constant propagation. (check-in: 50add839fd user: drh tags: propagate-const-opt) | |
| 23:47 | Generalize the constant propagation optimization so that it applies on every WHERE close, not just those that contain a subquery. This then demonstrates that the current implementation is inadequate since it does not take into account collating sequences. (check-in: 57eb2abd5b user: drh tags: propagate-const-opt) | |
| 21:48 | In the unix VFS, give every unixInodeInfo object its own mutex, rather than using the global VFS mutex, to improve concurrency in cases where there are many threads operating on separate database files. (check-in: 22f47cf430 user: drh tags: trunk) | |
