2022-08-22
13:34
Refactor JS API amalgamation such that the bootstrapping/configuration is deferred until the whole amalgamation is available, to facilitate providing clients with a way to initialize the API with their own config (noting that we're still one small level of refactoring away from being able to actually do that). (check-in: 9dbe9a6a user: stephan tags: fiddle-opfs)
08:55
wasm: accommodated a JS API rename. (check-in: 00991335 user: stephan tags: fiddle-opfs)
2022-08-18
15:53
Add notes to ext/wasm/README.md explaining how to run tests on a remote machine. (check-in: 7a3c444f user: drh tags: fiddle-opfs)
12:21
javascript: rename and simplify DB.callInTransaction() as DB.transaction(). Add DB.savepoint(), which works the same as transaction() but uses savepoints. Correct concatenation of arguments to SQLite3Error to use spaces instead of commas. Test that demo-oo1.js works with persistent OPFS storage (output differs due to persistent rows, but the demo works). (check-in: e8c323f1 user: stephan tags: fiddle-opfs)
11:16
Improve an exception check in demo-oo1.js. (check-in: 55e1b775 user: stephan tags: fiddle-opfs)
2022-08-17
18:07
Enhance the "PRAGMA integrity_check" statement so that it verifies the rows of a WITHOUT ROWID table are in the correct order. (check-in: 62f934bf user: drh tags: trunk)
17:14
Minor code simplification in the code generator for PRAGMA integrity check. (check-in: a3b9c7a6 user: drh tags: trunk)

2022-08-16
17:29
wasm: minor cleanups in the OO API #1 demo. (check-in: b9cdcc06 user: stephan tags: fiddle-opfs)

16:16
wasm: move another file and update testing1/testing2 to account for [e38d00c2b82d]. Disable wasmfs by default as it breaks the worker-based module loader (reason as yet unknown). (check-in: 6dad5e05 user: stephan tags: fiddle-opfs)

wasm: accommodate moving generated sqlite3.js in the previous checkin. (check-in: 41762f95 user: stephan tags: fiddle-opfs)

14:09
Omit an unnecessary test case from corruptN.test that does not work with the new RFC-7539 PRNG. (check-in: d9e8c65e user: drh tags: chacha20-prng)
10:52
Add assert() statements to verify that the SQLITE_OPEN_EXCLUSIVE flag is always passed to the VFS when opening a temporary file. (check-in: e123da49 user: dan tags: trunk)
00:04

18:36
The new --script option to dbtotxt.c looks for an SQL script at the head of the file and generates a CLI script that will construct the database then run the SQL. (check-in: 6170e638 user: drh tags: trunk)
12:26
In the documentation emphasize that the use of shared cache is discouraged. Fix test cases so that they all work with shared cache disabled. (check-in: 52c3ae06 user: drh tags: trunk)
2022-08-13
17:13
Add worker-style variant of the tests added in [ae24ac0f7dd9], but building this with wasmfs causes them to throw inexplicable exceptions from the Emscripten glue (without wasmfs it builds and runs fine, but storage is not persistent). (check-in: 6401595e user: stephan tags: fiddle-opfs)
16:36
wasmfs: use unix-none VFS by default to avoid locking errors in non-OPFS mode. (check-in: 75561dea user: stephan tags: fiddle-opfs)

13:56

13:51
Remove OPFS from the fiddle build for the time being - will re-enable once the breakage is figured out via testing with the core API. (check-in: 3bc510a6 user: stephan tags: fiddle-opfs)

2022-08-12
18:54

18:46
Add the (undocumented) SQLITE_DEFAULT_UNIX_VFS compile-time option. (check-in: 49828bde user: drh tags: trunk)
18:07
Updated fiddle deps to ensure that sqlite3.c is built first. (check-in: f0ca0261 user: stephan tags: fiddle-opfs)
17:57
Build fiddle with WASMFS OPFS support and attempt to use it if available. It does not work because of an inexplicable exception in Emscripten-generated code and perpetually-locked db, but it's not yet clear why. (check-in: a16f0a46 user: stephan tags: fiddle-opfs)
17:55
Minor wasm-related doc clarification and remove an obsolete code comment. (check-in: 1b1f650a user: stephan tags: trunk)

wasm refactoring part 2 of (apparently) 2: moved ext/fiddle/... into ext/wasm and restructured the core API-related parts of the JS/WASM considerably. (check-in: 27f9da4e user: stephan tags: wasm-cleanups)
09:36
wasm/fiddle refactoring part 1 of N: move fiddle app from ext/fiddle to ext/wasm/fiddle, which only contains files intended to be pushed to the live site. Disabled build of the non-fiddle wasm parts, pending a later step of the refactoring. (check-in: fb4eb930 user: stephan tags: wasm-cleanups)
