19:10 | Fix issues in LIMIT/OFFSET support for virtual tables. The first problem was reported by forum post c243b8f856. That report prompted an enhancement to the generate_series() (also included in this merge) which in turn identified other similar issues. (Leaf check-in: 5f6c079d user: drh tags: trunk) | |
18:42 | Internal JS doc touchups. No functional changes. (check-in: 626b997b user: stephan tags: trunk) | |
18:24 | Additional internal docs in the wasm utilities. (check-in: 5a2245a9 user: stephan tags: trunk) | |
18:13 | Allow virtual table implementations to handle OFFSET but not LIMIT, but not LIMIT but not OFFSET. (Closed-Leaf check-in: 90e5c822 user: dan tags: vtab-limit-fix) | |
17:19 | Have where.c ignore any plan from a virtual table that tries to use LIMIT/OFFSET without also using all WHERE constraints. (check-in: 7d305964 user: dan tags: vtab-limit-fix) | |
17:09 | Further fixes and improvements to the generate_series() enhancements on this branch. (check-in: b7d9bd7e user: drh tags: vtab-limit-fix) | |
14:36 | Use hex flag masks rather than decimals in ext/misc/series.c. (check-in: a94e2cd0 user: drh tags: vtab-limit-fix) | |
14:32 | Fix a problem allowing a LIMIT constraint to be passed to a virtual table in cases where there exist WHERE terms that cannot also be passed. (check-in: 72c8ed96 user: dan tags: vtab-limit-fix) | |
13:38 | Fix handling of LIMIT and OFFSET in virtual tables that are part of a compound SELECT. (check-in: 40421c1c user: drh tags: vtab-limit-fix) | |
13:30 | Enhance the generated_series() table-valued-function to respond to LIMIT and OFFSET. Use this to add new test cases for LIMIT and OFFSET on virtual tables in a compound SELECT. (check-in: 408d47ec user: drh tags: vtab-limit-fix) | |
12:01 | Add test demonstrating the problem at forum post c243b8f856. No fix yet. (check-in: 1685495c user: dan tags: vtab-limit-fix) | |

23:26 | Improvement to the way that affinity is determined for columns of a compound subquery. The affinity is the affinity of the left-most arm of the compound subquery that has an affinity other than NONE, adjusted to accommodate the data types coming out of the other arms. (check-in: e6df846f user: drh tags: trunk) | |
17:52 | Further improvements to the computation of affinity for compound subqueries: make sure that the selected affinity is compatible with a literal values in arms to the left of the arm that is used to determine affinity. (Closed-Leaf check-in: bbdf22e3 user: drh tags: compound-subquery-affinity) | |
16:55 | Back out the previous change on this branch. In its place: Determine the affinity of a subquery by the left-most arm of the subquery that has an affinity other than NONE. In other words, scan from left to right looking for an arm of the compound subquery with an affinity of BLOB, TEXT, INTEGER, or REAL and pick the first one found. Or stay with NONE if no arm has a defined affinity. Test cases added. (check-in: b8ec8511 user: drh tags: compound-subquery-affinity) | |
06:52 | wasm: add a makefile comment about the static sqlite3.h/c version info injected into the JS files possibly differing from the runtime-emited version info when a user provides their own sqlite3.c. (check-in: d99a01a0 user: stephan tags: trunk) | |

| ||
19:49 | An experimental minor tweak to the way affinities are computed for compound subqueries, when the actual affinity is ambiguous. (check-in: 779723ad user: drh tags: compound-subquery-affinity) | |
16:36 | If a RETURNING clause contains a subquery that references the table that is being updated in the statement that includes the RETURNING clause, then mark the subquery as correlated so that it is recomputed for each result and not just computed once and reused. See forum post 2c83569ce8945d39. (check-in: 9ea6bcc8 user: drh tags: trunk) | |
14:18 | Fix a case where a corrupt stat4 record could go unrecognized due to integer overflow. (check-in: 240a4a48 user: dan tags: trunk) | |
11:51 | Add comments linking the assert() added in [cef4d9e3ba586735] to the places where the precondition that the assert() tests are actually required. (check-in: 6f0e7e19 user: drh tags: trunk) | |
11:40 | Avoid slowdown when exprNodeIsConstant() is called on deeply nested SQL functions. (check-in: 1c0b0345 user: dan tags: trunk) | |
11:21 | Ensure that temporary SrcItem objects created by trigger processing have either SrcItem.zName or SrcItem.pSelect defined. Every SrcItem should have one or the other. (check-in: cef4d9e3 user: drh tags: trunk) | |
06:43 | Remove an undocumented feature from the JS Worker1.open API because it relies on broken behavior which has no VFS-agnostic workaround. (check-in: 3a640038 user: stephan tags: trunk) | |
2024-04-23

12:02 | Fix a problem with vector IN operators used with an index where the affinities and collations for the various vector terms are different. (check-in: 86e8c782 user: drh tags: trunk) | |
11:56 | Fix an uninitialized variable problem in the new code on this branch. (Closed-Leaf check-in: 85625b38 user: dan tags: vector-in-fix) | |
06:49 | Remove some dead WASM-side code. (check-in: 0a07ee27 user: stephan tags: trunk) | |

20:09 | Add extra tests for aborting conflicts in the sessions module. (check-in: b4a6d326 user: dan tags: trunk) | |
17:03 | Minor cleanups to [8fbda563d2f5]. (check-in: 5ee2594b user: stephan tags: trunk) | |
16:46 | Extend the JS/WASM SEE build support by (A) filtering SEE-related bits out of the JS when not building with SEE and (B) accepting an optional key/textkey/hexkey option to the sqlite3.oo1.DB and subclass constructors to create/open SEE-encrypted databases with. Demonstrate SEE in the test app using the kvvfs. This obviates the changes made in [5c505ee8a7]. (check-in: 8fbda563 user: stephan tags: trunk) | |
13:31 | Extra robustness in the code that causes cursors to return NULL when they are participating in an OUTER JOIN. (check-in: 672c2869 user: drh tags: trunk) | |
11:48 | For sqlite3.oo1.DB JavaScript classes, bypass execution of any on-open() SQL in SEE-capable builds because it would necessarily run before the client has an opportunity to provide their decryption key, which would leave the db handle in an unusable state and cause the ctor to throw. This currently affects only the OPFS VFSes. We may want to consider extending the ctor options object to optionally accept an SEE key and apply it when opening the db. (check-in: 5c505ee8 user: stephan tags: trunk) | |
00:42 | Continuation of the fix at [8c0f69e0e4ae0a44]: If a viaCoroutine FROM clause term is participating in a RIGHT or FULL JOIN, we have to create an always-NULL pseudo-cursor for that term when processing the RIGHT join. dbsqlfuzz 6fd1ff3a64bef4a6c092e8d757548e95698b0df5. (check-in: e1040e51 user: drh tags: trunk) | |

15:14 | Fix a problem where an expression like (a, b) IN (SELECT ...) might not use an index on (a, b) if the affinities and collation sequences of "a" and "b" are not identical. (check-in: 4d870fd8 user: dan tags: vector-in-fix) | |
2024-04-18

16:11 | Correct handling of OUTER JOIN when on or the other operand is a subquery implemented using the VALUES-as-coroutine optimization. dbsqlfuzz bde3bf80aedf25afa56e2997a0545a314765d3f8. (check-in: 8c0f69e0 user: drh tags: trunk) | |

No longer add sqlite3_wasm_extra_init.c to speedtest1.wasm because it's useless there. (check-in: 75fdd5b8 user: stephan tags: trunk) | |

This passes all TCL tests, but shows failures in the TH3 tests derived from forum post 6f842bc5b2dadcb2, presumably because the WHERE clause of the query uses constraints of the form "source_crs_code='8675'" instead of "source_crs_code=8675".

21:22 | Further fix for ticket [57c47526c34f01e8]. If a subquery has a result set column of the form "CAST(expr AS NUMERIC)" do not give that column NUMERIC affinity. NUMERIC affinity always goes to an integer if able, but a CAST to numeric is a no-op if the input is a number. So the two are not equivalent. (check-in: f0325359 user: drh tags: trunk) | |
18:58 | If a subquery has a result column of the form "CAST(... AS NUMERIC)" then give that column no affinity rather than NUMERIC affinity. This is because casting to numeric preserves real values that could be integers but numeric affinity does not.

23:46 | If the GENERATED keyword occurs before the AS keyword in a common table expression (CTE) definition, then that CTE becomes an "optimization barrier". For now, that means the CTE is always materialized. It also means that query flattener or pushdown optimizations that cross the CTE boundary are omitted. (check-in: 186ec18b user: drh tags: with-generated-as) | |
21:01 | Add a test-control that allows setting a LIKE pattern for common table expression names such that CTEs with matching names become an optimization barrier - They are not flattened and are implemented by materialization.

20:16 | Lexer and grammar rules for a RETURNING clause on DELETE/INSERT/UPDATE. Actually making this work, though, will involve a lot more code which will likely slow down processing for the common case where there is no RETURNING clause.

20:04 | For UPDATE and DELETE, use OP_DeferredSeek always. If the seek must later be resolved, add the OP_FinishSeek opcode after all WHERE clause terms have been processed. This obviates the need for the WHERE_SEEK_TABLE and WHERE_SEEK_UNIQ_TABLE flags to sqlite3WhereBegin() and the ensuing complication, and it allows the covering index optimization to be used further into WHERE clause processing.

20:43 | Minor code simplification. (check-in: 22ae8a52 user: drh tags: trunk) | |
20:15 | Add the "PRAGMA legacy_alter_table=ON" command to enable the pre-3.25.0 behavior of ALTER TABLE that does not modify the bodies of triggers or views or the WHERE clause of a partial index.

20:14 | Reduce the size of Expr to 64-bytes. This works somewhat, but there are test failures. More importantly, the size reduction from 80- to 64-bytes has not lowered the schema memory usage, but it has made the code a little bigger and a little slower. So the initial evidence is that this Expr refactoring experiment is not working... (Leaf check-in: 24b0f66a user: drh tags: expr-simplify) | |

20:28 | Remove an unused function declaration from fts5. (check-in: 148d9b61 user: dan tags: trunk) | |
19:52 | Add the "categories" option to the unicode61 tokenizer in fts5. (check-in: 80d2b9e6 user: dan tags: trunk) | |

19:39 | Merge latest begin-concurrent changes with this branch. (check-in: d33527d2 user: dan tags: begin-concurrent-pnu) | |
19:28 | Merge latest trunk changes into this branch. (check-in: 6a00a34e user: dan tags: begin-concurrent) | |
19:14 | Add a test-control to disable the skip-scan optimization. (check-in: 650a3fe0 user: dan tags: trunk) | |
11:28 | Add a test case to check that SQLITE_DBCONFIG_RESET_DATABASE can be used with wal mode databases even if there are active readers. (check-in: 6145f5b3 user: dan tags: trunk) | |

13:34 | On an UPSERT when the order of constraint checks is rearranged, make sure that the affinity transformations on the inserted content occur before any of the constraint checks. Fix for ticket [79cad5e4b2e219dd197242e9e5f4e]. (check-in: d120c45f user: drh tags: trunk) | |
03:27 | Adjustments to VdbeCoverage macros to deal with byte-code branches that can never be taken in some directions. (check-in: b170c009 user: drh tags: trunk) | |

23:31 | Remove incorrect ALWAYS() macros from the window function logic. (check-in: 94ac51cc user: drh tags: trunk) | |
22:24 | Add VdbeModuleComment()s on the three main code generators for window functions. (check-in: f7c239e9 user: drh tags: trunk) | |
20:50 | Minor comment changes. Add ALWAYS() macros on some unreachable branches in the xStep() methods of built-in window functions. (check-in: f2057542 user: drh tags: trunk) | |
19:48 | Identify Select objects within a single statement using small sequential integers rather than "0x%p". This is more readable and yields the same result on successive runs. (check-in: a7cdc5bc user: drh tags: trunk) | |
18:50 | Modify tests in window3.test to be tolerant of rounding errors when comparing floating point values. (check-in: 7c26c443 user: dan tags: trunk) | |
17:26 | Fix a problem with using scalar sub-selects in window function queries. (check-in: 687fe532 user: dan tags: trunk) | |
17:10 | Further improvements to bytecode branch testing. Fix cases where the macros said a branch could not be taken when in fact it could be. Alter some window function branch coverage macros to indicate that comparison operands cannot be NULL. (check-in: 76e42b70 user: drh tags: trunk) | |
16:04 | Enhancements and improved documentation to the byte-code branch coverage testing logic. Provide new macros that allow the code to specify that some branch instructions can never take the NULL path and that the OP_Jump opcode is only interested in equal/not-equal. The SQLITE_TESTCTRL_VDBE_COVERAGE file control callback now works slightly differently (it provides the callback with a bitmask of the branch action, rather than an integer). (check-in: cd2da7e1 user: drh tags: trunk) | |
15:55 | Experimental planner change to avoid a skip-scan if a regular index scan on the same index columns can be done instead. (Leaf check-in: 350f29ea user: dan tags: exp-begin-concurrent-pnu) | |
15:48 | Merge begin-concurrent changes into this branch. (check-in: af17432e user: dan tags: begin-concurrent-pnu) | |
15:45 | Merge latest trunk changes into this branch. (check-in: e9a3e864 user: dan tags: begin-concurrent) | |
07:39 | Fix a harmless warning about comment formatting in the previous check-in. Simplify the ORDER BY dereferencing logic so that it avoids unreachable branches. (check-in: 0f6ec605 user: drh tags: trunk) | |
07:25 | Assert that if two functions compare equal in every other way, then they must both have OVER clauses, or neither has an OVER clause. Use this fact to simplify expression comparison. (check-in: 52559ad5 user: drh tags: trunk) | |
06:47 | Enhance the sqlite3ExprCompare() routine so that it knows to compare the OVER clause of window functions. (check-in: 0a7649af user: drh tags: trunk) | |
06:32 | Enhance the TreeView mechanism so that it shows the window function data structures as part of the abstract syntax tree. (check-in: a2c0e1be user: drh tags: trunk) | |
05:11 | New VDBE comments and coverage macros. (check-in: a9a30726 user: drh tags: trunk) | |

20:41 | Add an ALWAYS() around a branch in sqlite3BtreeSkipNext() that we believe must always be true. (check-in: 12be361a user: drh tags: trunk) | |
18:55 | Avoid leaving view-definitions with an incomplete set of column names/types in the in-memory schema if an OOM strikes while allocating the same. (check-in: 1ddbb537 user: dan tags: trunk) | |
