In defensive mode, allow statements that write to shadow tables to be prepared from with virtual-table xSync() calls. (check-in: c8601d83 user: dan tags: trunk)
03:38
Fix minor spacing issues in the MSVC makefile. (check-in: d78c272b user: mistachkin tags: trunk)
2021-07-16
22:43
Try to omit the ORDER BY clause in subqueries if doing so does not change the result in any way. See Forum post 2d76f2bcf65d256a for details and history. (check-in: 85ddaf1b user: drh tags: trunk)
20:16
Minor comment improvements. (Closed-Leaf check-in: 6854b591 user: drh tags: omit-subquery-order-by)

17:04
Modify the generate_series() table-valued functions so that its first argument (the START value) is required. Throw an error if that argument is not supplied. In this was the series.c loadable extension can be used as a demonstration of how to code an xBestIndex function to require certain parameters. Compile with -DZERO_ARGUMENT_GENERATE_SERIES to obtain the legacy behavior. (check-in: 459d85a2 user: drh tags: trunk)
15:30
Fix the "main.mk" makefile so that "series.c" is a dependency of "shell.c". (check-in: ff959917 user: drh tags: trunk)

23:34
By default, do not emit #line directives in the amalgamation. (check-in: bacfa936 user: mistachkin tags: trunk)
19:29
Attempt to omit ORDER BY clauses from FROM-clause subqueries if those ORDER BY clauses do not affect the output. See forum thread 2d76f2bcf65d256a for discussion. This can help the query flattener in some cases, resulting in faster query plans. The current implemention does not always work. (check-in: ef97c3e7 user: drh tags: omit-subquery-order-by)
16:39
Change references to the schema table in sqlite3_analyzer to the new SQLITE_SCHEMA name. (check-in: 3beb77d6 user: drh tags: trunk)

14:59
Fix an assert() that might fail if sqlite3_create_function_v2() is invoked with NULL xStep and xFinal callbacks and a non-NULL xDestroy. (check-in: ab1550a6 user: dan tags: trunk)
13:52
Enhance the sqlite3_create_function() interfaces to assume a value of SQLITE_UTF8 is presented with a nonsense value for the preferred encoding. This is undocumented behavior added for robustness. (check-in: c1bb5cff user: drh tags: trunk)
11:52
Add the usual "#ifdef __cplusplus" magic to header file ext/misc/carray.h. Also update carray.h/carray.c to use SQLITE_API in the usual way. (check-in: 0f97c2a4 user: dan tags: trunk)
00:12

Rename optional SQLITE_CUSTOM_INC define to SQLITE_CUSTOM_INCLUDE. (check-in: 060aec37 user: mistachkin tags: trunk)
22:12
Allow library build to #include a user-specified header. (check-in: 71e6490b user: larrybr tags: trunk)
18:29
Preserve and return to the user any error message returned by a failed xConnect() call on an eponymous virtual table that prevents a query from being compiled. (check-in: bbbbeb59 user: dan tags: trunk)

Fix a harmless compiler warning - duplicate local variable named "pRHS". (check-in: 5bc05faf user: drh tags: trunk)
16:48
Follow-up to [68db1ff9c44fa9c3]: The number of registers needed by PRAGMA foreign_key_check was increased too late for an assert() deep down inside of sqlite3ExprCode(). So move the size increase a little earlier. Forum post 79c9e4797d. (check-in: 7072404a user: drh tags: trunk)
15:52
Fix a recently introduced segfault that might occur if a sub-select were used as a term on the RHS of an IN(...) operator for which the LHS is a row-value. (check-in: f586c06a user: dan tags: trunk)
13:53
Improve the error message in cases where there is a row-value on the LHS of an IN() operator, the RHS is a list (not a sub-select) and at least one element of the list is not a row-value with the correct number of elements. (check-in: 6b22f4e7 user: dan tags: trunk)
11:51
Instead of disallowing writes to fts5 tables if there are fts5vocab cursors open on them (commit [c49a6ed7]), abort any fts5vocab queries if the on-disk structure of the fts5 table changes. (check-in: 9dbdc900 user: dan tags: trunk)
2021-07-06
20:44
Handle "<vector> IN (<vector>, <vector> ...)" in the same way as "<vector> IN (VALUES(<vector>, <vector>, ...)". (check-in: 981d230e user: dan tags: trunk)
2021-07-05
19:01
Do not allow writes to an fts5 table if there are any open fts5vocab cursors. (check-in: c49a6ed7 user: dan tags: trunk)
18:37
Add the ATOMIC_INTRINSICS compile-time output output. Move sqlite3Int.h in front of ctime.c so that default values that are not overridden are shown in PRAGMA compile-time option output. (check-in: e3069526 user: drh tags: trunk)
17:15
Revert [5204c2c4a7b73a64], restoring the old pre-processor logic for determining the availability of the __atomic_store_n()/__atomic_load_n() primitives. (check-in: e690abb9 user: dan tags: trunk)
11:27
Allow sub-queries in the FROM clause of an UPDATE...FROM statement to access the object being updated without using an alias, as is required in the parent query. (check-in: 740cb430 user: dan tags: trunk)
02:40
Improved rebustness in sqlite3ExprListDup() when it contains a vector assignment from an UPDATE where the initial term is omitted. This can happen during a UNION ALL query flattening while processing a virtual table update in which the first term of the vector is repeated. Forum post 16ca0e9f32. (check-in: 2547cfe3 user: drh tags: trunk)
01:11
Ensure that TK_SELECT_COLUMN Expr nodes always have their iTable field set to to the number of columns in the vector. This is not strictly necessary. It just simplifies the state description and make the code easier to reason about. (check-in: 026f08d4 user: drh tags: trunk)
00:07
Fix an incorrect comment on testcase misc1-27.0. No changes to code. (check-in: 49829ae3 user: drh tags: trunk)
2021-07-04
22:33
Enhance the treeview debugging mechanism so that it correctly deals with TK_ROW expression nodes. (check-in: e87fdb65 user: drh tags: trunk)
2021-07-03
18:57
Fix a (harmless) typo in a comment. No code changes. (check-in: d2b9b8da user: drh tags: trunk)
02:55
In the PRAGMA foreign_key_check, ensure that sufficient registers are allocated for the virtual machine, even if one or more foreign keys reuses the same column multiple times and has more columns than the table it is part of. Forum post a6b0c05277. (check-in: 68db1ff9 user: drh tags: trunk)
2021-07-02
12:25
Put ALWAYS() on a branch that is always true due to [d4097364c511709b]. Fix a testcase precondition associated with the same check-in. (check-in: 55e2fbeb user: drh tags: trunk)
12:08
Fix a harmless assertion fault discovered by OSSFuzz. The assertion fault is harmless because the assert() checks a condition that that is harmless if false and the assert() is disabled in production builds. (check-in: 79443aab user: drh tags: trunk)
2021-07-01
18:19
Allow unqualified "rowid" references to be used in join queries, provided that only one of the source objects has a rowid. Forum post ab5b077c32636e49 (check-in: d4097364 user: dan tags: trunk)
16:57
Import the updated nmakehlp.c file used by the TCL Extension Architecture (TEA) builds in the amalgamation tarballs. Forum post 5a5001f20a. (check-in: 595bf95b user: drh tags: trunk)
2021-06-30
14:04
Fix a memory leak in fts5 that could occur when processing a query containing multiple classes of error. (check-in: 7c279670 user: dan tags: trunk)
12:11
Fix an assert() in fts5 that might fail when dealing with corrupt records. (check-in: 9e760e25 user: dan tags: trunk)
11:53
Do not enforce the SQLITE_LIMIT_FUNCTION_ARG limit for internally generated SQL. This prevents problems with statements like ALTER TABLE if the function argument limit is set too low. Forum post 17735aa21f3ddab2. (check-in: 763fdec5 user: drh tags: trunk)
2021-06-28
15:25
When generating data for a RETURNING clause, avoid assuming cursor number 0 is available for use. (check-in: 4b2c59ac user: dan tags: trunk)
2021-06-25
14:48
The OP_ReopenIdx opcode should clear the cursor if the cursor is being reused. This prevents leaving the cursor in an initialized state which could cause problems for a subsequent OP_SeekScan opcode. Fix for ticket [6dcbfd11cf666e21] and the OP_SeekScan optimization of check-in [4a43430fd23f8835]. (check-in: d4bf5243 user: drh tags: trunk)
11:21
Remove a redundant "ANALYZE" line from the ".fullschema" output. (check-in: 7b47f420 user: drh tags: trunk)
11:14
Fix a bug in the ".fullschema" dot-command of the CLI brought to light by check-in [a2ddb89b206c1387] - raising an error on at attempt to access the rowid of a subquery or view. (check-in: 36875827 user: drh tags: trunk)
00:25
Document sqlite3_wal_hook() return. (check-in: 8acaf796 user: larrybr tags: trunk)
2021-06-24
18:23
Allow the SQLITE_OPEN_EXCLUSIVE flag in sqlite3_open(). Return the SQLITE_CANTOPEN_EXISTS extended code to indicate that the open failed because the database already exists. (check-in: d091150f user: drh tags: trunk)
2021-06-23
17:41
Make conditional nature of sqlite3_normalized_sql() better known. (check-in: 0e0ece71 user: larrybr tags: trunk)
16:07
Fully incorporate *_changes64() API improvement. (check-in: 6699a2f6 user: larrybr tags: trunk)
11:39
Show CROSS JOINs in the TreeView debuggingn output. (check-in: 72e09b6c user: drh tags: trunk)
11:12
Fix a problem handling ORDER BY terms of the form "ORDER BY likely(<integer>)" within window frames. (check-in: 710f75b9 user: dan tags: trunk)
2021-06-22
23:24
When an index is used by all branches of the WHERE_MULTI_OR optimization and becomes a covering index, make sure the index has been created prior to NULLing it in the OP_NullRow opcode of a LEFT JOIN. See forum post 0575376e07. The covering-index for WHERE_MULTI_OR optimization was added by [62678be3df35cdcb]. Test cases are in the orindex01.test module of TH3. (check-in: 787c76a8 user: drh tags: trunk)
18:32
Add the sqlite3_changes64() and sqlite3_total_changes64() API functions. (check-in: 48fdec22 user: dan tags: trunk)
18:06
Fix a problem causing sqlite3_changes() to return an incorrect value following a "DELETE FROM tbl" command on an intkey table (because internal b+tree cells were being included in the count). (check-in: f662ff47 user: dan tags: trunk)
14:59
Ensure that the cell array used in balance_nonroot() is always large enough, even if the pages being balanced are corrupt. (check-in: 53f64e83 user: dan tags: trunk)
2021-06-20
22:52
Load recent dbsqlfuzz cases into test/fuzzdata8.db. (check-in: a766bba0 user: drh tags: trunk)
22:49
Remove a NEVER() that is reachable by a corrupt database. dbsqlfuzz 8456a0f88e39a49fb675d8f77394979ebb2a03c1. Test case in TH3. (check-in: 1c41e86f user: drh tags: trunk)
22:17
Do not allow an SQLITE_CORRUPT error to mask a prior SQLITE_IOERR in balance_nonroot(). dbsqlfuzz 5e1c86e7f18023f2b9abe3429977d7ea726f50d8 (check-in: 50e81876 user: drh tags: trunk)
2021-06-19
20:20
Remove unnecessary (redundant) variable initialization from sqlite3BtreeInsert() for a small size reduction and performance increase. (check-in: 70d18364 user: drh tags: trunk)
18:35
The previous check-in is a significant change to btree, so go ahead and increment the version number for the next development cycle. (check-in: 2eb66970 user: drh tags: trunk)
18:32
Split the sqlite3BtreeMovetoUnpacked() routine into two separate routines sqlite3BtreeTableMoveto() and sqlite3BtreeIndexMoveto(), since we usually know the type of btree in advance. This results in less branching and better performance. (check-in: 3b0d34e5 user: drh tags: trunk)
2021-06-18
18:36
Version 3.36.0 (check-in: 5c9a6c06 user: drh tags: trunk, release, version-3.36.0)
