| 16:24 | Ensure the RETURNING clause is honoured when a row of a temp table is updated by an ON CONFLICT clause. (check-in: ac9568cf user: drh tags: branch-3.40) | |
| 16:12 | Add the SQLITE_FCNTL_RESET_CACHE verb. Use it to ensure that the page cache is purged before and after a the recovery extension is run. (check-in: 71dd920f user: drh tags: branch-3.40) | |

| 15:55 | Fix a off-by-one error in code generation that comes up when doing a DISTINCT query against a virtual table with an OR term in the WHERE clause and where the ORDER BY clause has 64 or more references to the result set. Forum post dfe8084751. The error is harmless in production builds, but might cause an assertion fault in a debugging build. (check-in: cbcd7d9b user: drh tags: branch-3.40) | |
| 15:44 | Fix safe mode authorizer callback to reject disallowed UDFs. Reported at Forum post 07beac8056151b2f. (check-in: 70964b8a user: drh tags: branch-3.40) | |
| 15:21 | Fix an infinite loop in the MEMSYS5 auxiliary memory allocator that occurs for memory allocations between 500MiB and 1GiB in size. Error introduced by check-in [949133231f8f751a]. The problem only affects builds that include the SQLITE_ENABLE_MEMSYS5 compile-time option. (check-in: c10d40ca user: drh tags: branch-3.40) | |

| 11:50 | Install sqlite3_malloc/sqlite3_free() as the JS-side WASM allocator (as opposed to replacing C-level's malloc()/free() with them). All tests work and this eliminates the potential for allocator discrepancies when using the (de)serialize APIs. (check-in: 95c78f6b user: stephan tags: trunk) | |
| 08:37 | Simplify how the OPFS VFS async proxy copies initial state sent to it from the synchronous side of the connection. Make the lock-wait time a multiple of the wait-loop timeout interval. (check-in: eddafaff user: stephan tags: trunk) | |
| 07:48 | OPFS VFS: remove an invalid TODO and fix a property name typo which caused xCheckReservedLock() to always report false. (check-in: 3b037caa user: stephan tags: trunk) | |
| 07:17 | Rename some OPFS JS files. Prevent JS bindings of sqlite3_uri_...() from performing JS-to-C-string argument conversion on their first argument, as doing so is specifically illegal. (check-in: 79832808 user: stephan tags: trunk) | |
| 05:27 | Refactor a significant chunk of the OPFS sqlite3_vfs init code into sqlite3.VfsHelper, and internal-use-only API encapsulating code relevant to creating new VFSes in JS. Intended to assist in pending experimentation with an alternative OPFS VFS. (check-in: e25d7b08 user: stephan tags: trunk) | |

| 18:28 | sqlite3.oo1.OpfsDb: default to journal_mode=persist, as current tests show it to be marginally faster than truncate/delete in Chrome v109. Also increase default busy_timeout from 2 seconds to 3, admittedly on a whim. (check-in: d0c8fa30 user: stephan tags: trunk) | |
| 18:00 | OPFS speedtest1: hide a currently-broken/to-fix WASMFS-build link. (check-in: cde95d38 user: stephan tags: trunk) | |
| 17:52 | Change the handling of hwtime.h to make it easier to compile performance measurement builds that make use of hwtime.h. This should not affect productions builds. (check-in: f64a2242 user: drh tags: trunk) | |
| 11:28 | Fix legacy build system main.mk to include basexx.c in testfixture builds. (check-in: 8c9200b7 user: dan tags: trunk) | |
| 06:56 | Rename one instance of opfs.OpfsDb to oo1.OpfsDb, as per [0c5c51f4fb04]. (check-in: 75b04c9b user: stephan tags: trunk) | |
| 06:09 | Minor internal cleanups and docs in the OPFS sqlite3_vfs. (check-in: 61799b05 user: stephan tags: trunk) | |
| 05:25 | Internal restructuring of the OPFS sqlite3_vfs in order to facilitate certain experimentation and improve error reporting/hints if it cannot be activated. Deprecate the name sqlite3.opfs.OpfsDb, preferring sqlite3.oo1.OpfsDb for consistency with JsStorageDb and any future DB subclasses. (check-in: 0c5c51f4 user: stephan tags: trunk) | |
| 02:23 | Add an explicit warning about the current API-instability of the sqlite3.opfs namespace, which may need to be eliminated based on re-thinking of how the OPFS sqlite3_vfs is registered. Comment changes only - no code. (check-in: 0cb2fd14 user: stephan tags: trunk) | |

| 16:11 | Merge trunk changes into covering-index-expr branch. (check-in: 89d775ad user: drh tags: covering-indexed-expr) | |
| 15:23 | Rework the covering index checking routine, whereIsCoveringIndex(), so that it can return a "maybe" result for aggregate queries where we are not exactly sure. The index is scored as if it is covering, but the main table is still opened. (check-in: b8eec421 user: drh tags: covering-indexed-expr) | |
| 14:51 | Add (optional) base64 and base85 UDF extensions. (check-in: b44ab10c user: larrybr tags: trunk) | |
| 14:11 | Sync w/trunk, zap surplus space. (Closed-Leaf check-in: b8345630 user: larrybr tags: base_convert) | |

| 20:12 | Fix an incorrect assertion-fault in the "TREETRACE" debugging logic on select.c. The problem does not affect production builds. (check-in: f11bb422 user: drh tags: trunk) | |
| 15:24 | OPFS VFS: add the opfs-unlock-asap=1 URI flag which tells the VFS to release implicit locks ASAP instead of during VFS idle time. This improves concurrency notably in the test app but brings a significant performance penalty in speedtest1 (roughly 4x slowdown). This is not the final word in OPFS concurrency, but gets us a step further. (check-in: 9542f9ce user: stephan tags: trunk) | |
| 14:19 | Experimental changes to help the query planner detect when an expression index is coverting. Works somewhat, but there are tests that fail. (check-in: 968c189b user: drh tags: covering-indexed-expr) | |

| 16:32 | Fix #ifdefs so that restrictions (8) and (9) of the push-down optimization are still enforced even if compiled with SQLITE_OMIT_WINDOWFUNC. This fixes a bug introduced by check-in [346a3b12b861ce7b]. (check-in: 09e1e42e user: drh tags: trunk) | |
| 16:10 | Improve the query planner such that it is able to make use of indexed expressions within an aggregate query with GROUP BY. This implements enhancement request [99378177930f87bd]. (check-in: b9190d3d user: drh tags: trunk) | |
| 15:52 | Add restriction (9) to the push-down optimization: If the subquery is a compound then all arms of the compound must have the same affinity. dbsqlfuzz 3a548de406a50e896c1bf7142692d35d339d697f. (check-in: 1ad41840 user: drh tags: trunk) | |

| 19:02 | Take care not to try to add comments to a TK_AGG_COLUMN opcode that does not have an associated Table object because it is a reference to an indexed expression. (check-in: 5fc23863 user: drh tags: agg-with-indexed-expr) | |
| 18:45 | Change a NEVER() into an assert(). (check-in: a0fd44f4 user: drh tags: agg-with-indexed-expr) | |

| 02:35 | Add sqlite3.oo1.DB.prototype.checkRc() and tests for both that method and its class-level counterpart. (check-in: f7eaa6ba user: stephan tags: trunk) | |
| 01:41 | Merge the latest trunk changes into the agg-with-indexed-expr branch to simplify diffs. (check-in: 38c3d3f1 user: drh tags: agg-with-indexed-expr) | |

| 19:03 | Add an experimental OPFS VFS-specific URI flag, opfs-unlock-asap, which tells the VFS to release implicit locks ASAP. This permits higher concurrency but hurts performance considerably. This may or may not be obsoleted by other concurrency-related experimentation. (check-in: d23c9170 user: stephan tags: opfs-unlock-asap) | |
| 18:51 | Aggregates with GROUP BY now make use of expressions on indexes. This code works and gets the correct answer for the test case in the ticket. Lots more testing and documentation is needed, however. (check-in: 8dcf9f20 user: drh tags: agg-with-indexed-expr) | |
| 17:56 | This attempt at modifying AggInfo to make use of indexed expressions does not work. It gets an incorrect answer for the test case shown in the ticket. (check-in: 84c06023 user: drh tags: agg-with-indexed-expr) | |

| 16:08 | Update Makefile.in to include new target "sqlite3r.c". For generating "sqlite3r.c" and "sqlite3r.h", versions of the amalgamation that include the recover extension. To build the shell tool against these files, add -DSQLITE_HAVE_SQLITE3R. (check-in: 5f135575 user: dan tags: trunk) | |

Renumber all of the bits in the bitmask used to enable various kinds of tracing, and add a trace bitmap decoder in sqliteInt.h. Changes to debugging logic only. No (intentional) changes to production code. (check-in: 8036445a user: drh tags: trunk) | |
