| 23:04 | Revise the strategy used by the star-query heuristic: Instead of decreasing the cost of all fact-table WhereLoops, increase the run-cost of WhereLoops that are SCANs of dimension tables. (check-in: 1bc09c9e user: drh tags: trunk) | |
| 14:30 | Improvments to debug output on the star-query heuristic. (check-in: b3ebeb06 user: drh tags: trunk) | |

| 22:23 | wasm: de-list demo-worker1-promiser-esm.html from the test pages because (per Chrome 131) "Module scripts don't support importScripts()", where "don't" means "they used to but no longer do". (check-in: 4aa025a9 user: stephan tags: trunk) | |
| 21:06 | Fix a possible infinity loop in debugging-printf logic in the query planner. No changes to production code. (check-in: 9a20b940 user: drh tags: trunk) | |
| 19:44 | When running wasm-opt, ignore any failure because it will fail for unknown flags and the set of legal flags will change from version to version. Document the size-reduction effect (or non-effect) of a dozen-odd wasm-opt flags and retain those which demonstrate a wasm file size reduction in -Oz builds (our production build mode). Total size savings: roughly 13kb. (check-in: c9dc581e user: stephan tags: trunk) | |
| 16:11 | Remove some now-dead makefile code, rename a var for consistency, and fix a recipe bug introduced in the previous checkin in the bundler-friendly build. (check-in: 0acd4ef3 user: stephan tags: trunk) | |
| 15:58 | Initial support for post-processing wasm files with wasm-opt (if it's available). This currently shaves 12kb off of the release-mode build of sqlite3.wasm but there are many dozens of wasm-opt flags left to try. (check-in: 5d16e3f2 user: stephan tags: trunk) | |
| 14:09 | Move small parts of ext/wasm/GNUmakefile into ext/wasm/config.make.in and have the configure script populate that, rather than dynamically determining those values on each 'make' invocation. Add a configure-time check for the optional wasm-opt binary in prep for pending experimentation with using it to reduce the wasm file sizes. (check-in: 0a426a54 user: stephan tags: trunk) | |
| 11:42 | Have fts5 better handle OOM errors from sqlite3_blob_close(). (Leaf check-in: 7ffa7e02 user: dan tags: branch-3.48) | |
| 11:21 | Remove unnecessary --minify 0 emcc flag from the wasm build, as -g3 implies that capability along with other anti-minification features we rely on. (check-in: 10c91f9c user: stephan tags: trunk) | |
| 06:12 | Do not strip binaries during 'make install', for consistency with the legacy build and per request from package maintainers. (check-in: 92b06a4c user: stephan tags: branch-3.48) | |

| 19:37 | Add two new sqlite3_db_config() options that enable the ATTACH command to create new database files and to open databases read/write. Both default to on for backwards compatibility. (Leaf check-in: fe0c58d0 user: drh tags: enable-attach) | |
| 17:18 | Add the -q/--quiet option to test/speedtest.tcl. Automatically enable -DSQLITE_OMIT_LOAD_EXTENSION and -DSQLITE_THREADSAFE=0 so that no extra libraries are required. (check-in: c20d21b4 user: drh tags: trunk) | |

| 15:12 | The FuncDev.nArg field values -3 and -4 now have special meansing of 1 or more or 2 or more arguments, respectively. This saves space in the built-in function table, resulting in slightly faster performance and a reduced binary size. (check-in: 753fd747 user: drh tags: trunk) | |
| 14:40 | Remove now-extraneous autoconf/INSTALL and autoconf/configure.ac and update autoconf/README.* to account for the port to autosetup. (check-in: 646667af user: stephan tags: autoconf-to-autosetup) | |

| 23:49 | For the purpose of the query planner heuristic added by [38db9b5c83], a query should only count as a star query if the fact tables are connected to the dimension table by an INNER JOIN. If a LEFT JOIN is used, then the fact tables are constrained to be in inner loops anyhow and so the heuristic does not make any sense. But it does interfere with AUTOMATIC index creation, which causes the performance regression reported by forum post d87570a1455. (check-in: 0852c57e user: drh tags: trunk) | |

| 13:10 | wasm: after generating the .js/.mjs file, strip out all of the generated pieces which create Emscripten call() bindings for the sqlite3 APIs, as we don't use those binding, so both the setup time and the memory they use installing WASM proxy bindings is wasted. This eliminates some 200 superfluous/unused bindings from the init process. (check-in: 020d2c75 user: stephan tags: trunk) | |
