| 11:35 | Minor touchups to the JS test index page and test server push rules. (check-in: 0881f3e923 user: stephan tags: trunk) | |
| 10:43 | wasm builds: explicitly set a default stack size because emsdk 3.1.27 reduced it from 4MB to only 64kb, leading to memory corruption when kvvfs is used (it requires at least twice that for I/O). (check-in: 758112460f user: stephan tags: trunk) | |
| 09:23 | wasm: after building snapshot zip file, emit instructions for pushing it to the test server. (check-in: 9615c77919 user: stephan tags: trunk) | |
| 08:51 | Correct the problem which triggered the rollback in [7eec635562f6]: an incorrect default db page size (not a multiple of 512 bytes). (check-in: e06e490c24 user: stephan tags: trunk) | |
| 08:38 | Roll back the SQLITE_DEFAULT_PAGE_SIZE part of [c260895faacb34] because kvvfs does not work at all with a page size of 8kb. (check-in: 7eec635562 user: stephan tags: trunk) | |
| 08:29 | sqlite3-wasm.c: code legibility and coding style tweaks. Increase SQLITE_DEFAULT_PAGE_SIZE from 4k to 8k, as that improves OPFS speedtest1 performance by roughly 12%. (check-in: c260895faa user: stephan tags: trunk) | |
| 07:14 | Expand JS tests for db export/import and document reason it cannot currently work with kvvfs. Fix a minor JS build dependencies bug. Update page title with PASS/FAIL prefix for tester1.js to improve overview when launching multiple test tabs. Add ability of tester1 should-run-test predicates to report why a given test is disabled. (check-in: 75f610d3a4 user: stephan tags: trunk) | |
| 03:37 | Remove extraneous/unused sqlite3.oo1.version object. Add httpd makefile target. (check-in: 8e4d30ac03 user: stephan tags: trunk) | |
| 03:35 | Experimental branch for more flexible selection of extensions and localization of details of incorporation by host. A WIP for now. (check-in: 98be19ba83 user: larrybr tags: extension_opts) | |

| 18:15 | Optimizations to exprAnalyze() and sqlite3WhereExprUsage() save about 1.5 million CPU cycles for speedtest1, and result in a smaller binary. (check-in: 1f2252e65d user: drh tags: trunk) | |
| 18:09 | Merge for CLI fix. (check-in: 98cf18611d user: larrybr tags: cli_extension) | |
| 14:28 | Move the TK_IS token so that it is adjacent to the TK_IN token, as this allows the C compiler to optimize better, resulting in a slightly smaller and faster executable. (check-in: 8832fa9088 user: drh tags: trunk) | |
| 14:16 | In the shell tool, avoid modifying internal data structures until after the arguments to ".open" have been parsed. (check-in: fcc509d325 user: dan tags: trunk) | |
