2022-11-30
| ||
| 21:18 | Add a testcase() macro to verify that the case of a NOT NULL error message hitting the string length limit. (check-in: 91f50964 user: drh tags: trunk) | |
| 20:22 | Fix an over-zealous assert() reported by Yong Heng. (check-in: 6ee61f8c user: drh tags: trunk) | |
| 19:11 | Attempt to rationalize the bits associated with ".wheretrace". Provide a decoder key in sqliteInt.h for what each bit is intended to do. (check-in: 8ec36169 user: drh tags: trunk) | |
| 18:21 | Rename some JS files from X.js to X.c-pp.js to keep the maintainer, and downstream build customizers, aware that those files contain constructs specific to the c-pp preprocessor and will not run as-is in JS. (check-in: 2eade7c7 user: stephan tags: trunk) | |
| 13:55 | • Edit [6620c57b9d3eae72|6620c57b]: Edit check-in comment. (artifact: 50838a29 user: drh) | |
| 13:44 | Always use nanosleep() (instead of usleep() or sleep) if the _POSIX_C_SOURCE macro says it should be available. See Fossil Forum post ab2e2593ae307946 for driver behind this enhancement. (check-in: 6620c57b user: drh tags: trunk) | |
| 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) | |
| 10:05 | Merge trunk into wasi-patches branch. (check-in: 64cf34a8 user: stephan tags: wasi-patches) | |
| 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) | |
| 03:08 | Doc and logging text tweaks in the OPFS async proxy and test app. (check-in: 7ce8608e user: stephan tags: trunk) | |
|
2022-11-29
| ||
| 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) | |
|
2022-11-28
| ||
| 21:17 | Check-in [8d5b76593d82b3a5] contained an error that was causing some obscure error codes to be lost. Fixed here. (check-in: 46cdd363 user: drh tags: trunk) | |
| 21:09 | Get ext/misc/basexx.c into the testfixture.exe build for MSC. (check-in: bb2c5d08 user: larrybr tags: trunk) | |
| 20:08 | Fix harmless compiler warnings. (check-in: 8d5b7659 user: drh tags: trunk) | |
| 19:43 | • Fixed ticket [695a1a53]: Better choice of indexes with covering indexes on expressions plus 3 other changes (artifact: 82a25833 user: drh) | |
| 19:42 | Implementation of enhancement request [695a1a53dea6b240]: The query planner has improved awareness of when indexes on expressions are covering and adjusts their costs accordingly. (check-in: e3474d79 user: drh tags: trunk) | |
| 18:41 | 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: 6db0bc4b user: dan tags: trunk) | |
| 18:17 | Test cases added derived from the enhancment ticket. (Leaf check-in: c022c015 user: drh tags: covering-indexed-expr) | |
| 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) | |
| 14:53 | • Edit [b8345630a2a32223|b8345630]: Mark "Closed". (artifact: e082157b user: larrybr) | |
| 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) | |
| 13:47 | Ensure the RETURNING clause is honoured when a row of a temp table is updated by an ON CONFLICT clause. (check-in: a2449bcc user: dan tags: trunk) | |
| 02:28 | Conform CLI .trace arg handling to its help. (check-in: 31546ea3 user: larrybr tags: trunk) | |
|
2022-11-27
| ||
| 00:57 | Document an OPFS API change in Chrome v108 which does not break our code but does change several formerly async methods to synchronous. No code changes. (check-in: e9dd87e2 user: stephan tags: trunk) | |
|
2022-11-26
| ||
| 20:52 | Better reporting of when the WHERE clause analysis thinks that an index is covering. (check-in: 17ebcf31 user: drh tags: covering-indexed-expr) | |
| 20:48 | Show which AggInfo.aCol an Expr node represents in the tree trace debugging logic. Does not affect production builds. (check-in: b8076f4d user: drh tags: trunk) | |
| 20:13 | Merge trunk fixes into the covering-indexed-expr branch. (check-in: 9ac67ff9 user: drh tags: covering-indexed-expr) | |
| 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) | |
|
2022-11-25
| ||

| 17:05 | Relax restriction (8) on the push-down optimization so that it only applies if one or more columns uses a collating sequence other than BINARY. See forum post 3824ced748baa808 and check-in [346a3b12b861ce7b]. (check-in: adbca344 user: drh tags: trunk) | |
| 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) | |
| 16:12 | • Fixed ticket [99378177]: Use indexed expressions in an aggregate query plus 6 other changes (artifact: fb3dc805 user: drh) | |
| 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) | |

|
2022-11-24
| ||
| 23:35 | Correctly deal with IF-NULL-ROW operators when dealing with indexed expressions in aggregates. (check-in: 939cb470 user: drh tags: agg-with-indexed-expr) | |
| 20:11 | Speed up base85() conversions and sync w/trunk. (check-in: 17b82350 user: larrybr tags: base_convert) | |
| 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) | |
| 18:36 | • Edit [ed14863dd72e35fa|ed14863d]: Edit check-in comment. (artifact: 364cc633 user: drh) | |
| 18:22 | • Edit [346a3b12b861ce7b|346a3b12]: Edit check-in comment. (artifact: f426a484 user: drh) | |

| 17:53 | More work on the OPFS concurrency testing app. (Closed-Leaf check-in: c0458cac user: stephan tags: opfs-unlock-asap) | |
| 16:03 | JS documentation cleanups. No code changes. (check-in: 18e89a43 user: stephan tags: trunk) | |
| 15:32 | Update multiplex3.test to account for the fact that the multiplexor xDelete method may return an error even if it manages to delete the first chunk of a file. (check-in: 1a7f3254 user: dan tags: trunk) | |
| 15:04 | Add NEVER() and ALWAYS() macros on branches that are believed to be unreachable. (check-in: 3a901e88 user: drh tags: agg-with-indexed-expr) | |

| ||
| 21:09 | Minor JS doc updates. (check-in: 27efd63a user: stephan tags: trunk) | |
| 21:03 | Add optional zSchema argument to sqlite3_js_db_export(). (check-in: 9c23644b user: stephan tags: trunk) | |
| 20:49 | OPFS concurrency test: add a URL flag to enable/disable unlock-asap mode. (check-in: 1c1bf22e user: stephan tags: opfs-unlock-asap) | |
| 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) | |
| 19:02 | • Edit [c5b7a9715a13b696|c5b7a971]: Move to branch opfs-unlock-asap. (artifact: 37daa39d user: stephan) | |
| 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) | |
| 16:39 | Initial infrastructure for adding a mode to the OPFS VFS which causes implicit locks to be released ASAP, which increases concurrency at the cost of performance. (check-in: c5b7a971 user: stephan tags: opfs-unlock-asap) | |
| 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) | |

| 20:37 | Add the stub function: optimizeAggregateUsingIndexedExpr(). The hope is that we can fill this in with a routine that does useful optimizations. (check-in: d85bb724 user: drh tags: agg-with-indexed-expr) | |
| 20:04 | Avoid naming collision between the sha1 and shathree extensions. (check-in: 9ec923b5 user: mistachkin tags: trunk) | |
| 19:56 | Include the treetrace bitmap comment accidentally omitted from the previous check-in. (check-in: db07471c user: drh tags: trunk) | |
| 19:51 | Merge trunk fixes and enhancements into the agg-with-indexed-expr branch. (check-in: 07063478 user: drh tags: agg-with-indexed-expr) | |
| 19:49 | Rename the SELECTTRACE macro to TREETRACE, so that is corresponds to the new CLI command. 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) | |
| 19:12 | Sync w/trunk. Ready for merge to trunk. (check-in: ff67460e user: larrybr tags: base_convert) | |

| 15:43 | Since the memory registers used by the columns and functions of an AggInfo object are sequential, it is not neecessary to remember each register separately. We can simply remember the first one and do the math when others are needed. (check-in: dc5bd349 user: drh tags: agg-with-indexed-expr) | |

| 17:40 | Split out the debugging code that dumps an AggInfo object into a separate subroutine called printAggInfo() so that it can be invoked interactively during debugging. No changes to production code. (check-in: dc33cfbe user: drh tags: trunk) | |
| 16:40 | Change the name of the Parse.pIdxExpr field to pIdxEpr so that the name is distinct from all other identifiers in the code and thus less confusing. (check-in: a2962d01 user: drh tags: trunk) | |
| 16:03 | Merge trunk into wasi-patches branch to clean up the diff view. (check-in: 95de6742 user: stephan tags: wasi-patches) | |

| 03:50 | Add test app for experimenting with multi-worker OPFS concurrency. Tweak OPFS VFS to significantly improve the otherwise "unfortunate" concurrency situation. (check-in: 96f76e76 user: stephan tags: trunk) | |
| 02:18 | Get clean builds for MS tools. Add build examples for extension glommer (basexx.c) Make sure extensions build for dynamic load and built into shell. (check-in: da940d50 user: larrybr tags: base_convert) | |
| 00:11 | Fix a base64 decode bug. Provide for convenient inclusion of extension(s) built into the CLI, to simplify testing and for its own sake. Improve comments. Cure collision between base64.c and base85.c when both are in the same translation unit. (check-in: 07543d23 user: larrybr tags: base_convert) | |
