Add wasm.cArgvToJs() to support sqlite3_module::xConnect(). (check-in: c3ebdccf user: stephan tags: wasm-vtab)
08:21
Minor internal JS code/docs cleanups. (check-in: 21331bdd user: stephan tags: wasm-vtab)
06:16
Minor test tweaks. (check-in: f902f3b2 user: stephan tags: wasm-vtab)
06:09
Add a demonstration sqlite3_vtab/module implemented in JS, based on ext/misc/templatevtab.c. Add oo1.selectArrays() and selectObjects(). (check-in: 60482c97 user: stephan tags: wasm-vtab)
2022-12-05
18:26
Merge latest trunk changes. (check-in: 1a72777b user: dan tags: scanstatus_v2)
15:05
Remove two features of jaccwabyt which were fundamentally flawed, along with approx. 250 lines of unit tests which heavily relied on them. Thankfully, none of the sqlite3.js-level code used those bits. (check-in: a190abc3 user: stephan tags: wasm-vtab)
14:32
Jaccwabyt (JS) doc updates. (check-in: a329a809 user: stephan tags: wasm-vtab)
14:13
Expose sqlite3_get/set_auxdata() to wasm. Minor test app CSS tweaks. (check-in: 44659ad3 user: stephan tags: wasm-vtab)
13:33
Export collation-related APIs and strncmp()/strnicmp() to wasm. (check-in: c3c56d9b user: stephan tags: wasm-vtab)
13:12
Export sqlite3_vtab_collation() to wasm. Rename 'flexible-string' JS argument adapter to 'string:flexible' for consistency. (check-in: 15f8042f user: stephan tags: wasm-vtab)
11:54
Rename 'static-string' argument adapter to 'string:static'. Replace JS unit tests which were lost via editing a generated copy of tester1.js instead of the original tester1.c-pp.js input file. (check-in: 9d81d51d user: stephan tags: wasm-vtab)
11:30
Export sqlite3_bind/value/result_pointer() to wasm. Add 'static-string' argument converter to support the lifetime requirements of bind/result_pointer()'s string argument. Correct an endless loop in wasm.cstrlen() when passed a non-C-string argument. (check-in: a9455243 user: stephan tags: wasm-vtab)
07:51
More work on the JS side of the virtual table APIs. (check-in: cb9881ec user: stephan tags: wasm-vtab)
05:45
Remove some dead code. Improve some error checks and comments. (check-in: 6712fbe4 user: stephan tags: wasm-vtab)
05:30
Initial infrastructure for adding virtual table/table-valued function support to WASM. (check-in: c202d7a0 user: stephan tags: wasm-vtab)
2022-12-04
08:16
Export sqlite3_result_zeroblob/zeroblob64() to wasm. (check-in: a60e5662 user: stephan tags: trunk)
2022-12-03
15:41
Correct a memory leak in tester1.js. (check-in: e42b052d user: stephan tags: trunk)
14:58
sqlite3.wasm.allocFromTypedArray() now optionally accepts an ArrayBuffer as its argument. (check-in: 75a1a796 user: stephan tags: trunk)
13:10
Rename wasm.xWrap.resultAdapter() X:free entries to X:dealloc for consistency with wasm.dealloc(). Add an undocumented feature to replace wasm.alloc/dealloc/realloc() with the C-standard allocators (after an allocator misuse led down a several-hour rabbit hole trying to discover a mis-free() violation). Related test updates. (check-in: d9807656 user: stephan tags: trunk)
11:16
JavaScript: add sqlite3.wasm.realloc(), sqlite3.capi.SQLITE_MAX_ALLOCATION_SIZE, and related tests. (check-in: eeb84ba5 user: stephan tags: trunk)
03:06
wasm build: rename the path to the wasm docs checkout, for clarity and consistency. (check-in: b820db32 user: stephan tags: trunk)
02:42
wasm snapshot and doc-related build automation tweaks. (check-in: 13eb1abd user: stephan tags: trunk)
01:59
Rework the oo1.DB's distinct-per-VFS post-open() step to accept either a batch of SQL or a callback function. Increase OPFS's busy timeout to 10s. (check-in: 9feefe25 user: stephan tags: trunk)
2022-12-02
18:56
Minor internal tweaks to the OPFS VFS. Resolve a missing result code which lead to a null deref in xFileSize(). (check-in: 57dd593e user: stephan tags: trunk)
18:06
OPFS VFS: translate createSyncAccessHandle() exceptions which appear to be locking violations to SQLITE_BUSY. This seems to improve concurrency considerably even with a reduced retry count of 5 (was 6). (check-in: 0d36021d user: stephan tags: trunk)
11:35
Minor touchups to the JS test index page and test server push rules. (check-in: 0881f3e9 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: 75811246 user: stephan tags: trunk)
09:23
wasm: after building snapshot zip file, emit instructions for pushing it to the test server. (check-in: 9615c779 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: e06e490c 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: 7eec6355 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: c260895f 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: 75f610d3 user: stephan tags: trunk)
03:37
Remove extraneous/unused sqlite3.oo1.version object. Add httpd makefile target. (check-in: 8e4d30ac user: stephan tags: trunk)
2022-12-01
15:22
sqlite3_js_create_file() now accepts an ArrayBuffer data source. Add test for OPFS-based export/re-import. The (sqlite3*) argument converter now optionally accepts sqlite3.oo1.DB instances. (check-in: 14a84b67 user: stephan tags: trunk)
04:45
Reformulate and simplify some JS tests related to the previous checkin. (check-in: 9ea2d3dc user: stephan tags: trunk)
03:55
Expand "sqlite3_vfs*" JS-to-WASM function argument conversions to accept VFS names (JS strings) and capi.sqlite3_vfs instances. Implement sqlite3_js_vfs_create_file() to facilitate creation of file-upload features which store the file in VFS-specific storage (where possible, e.g. "unix" and "opfs" VFSes). Correct an argument type check in the SQLite3Error and WasmAllocError constructors. (check-in: e1009b16 user: stephan tags: trunk)
2022-11-30
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)
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. (Leaf 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)
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
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)
16:11
Merge trunk changes into covering-index-expr branch. (check-in: 89d775ad 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)
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
20:13
Merge trunk fixes into the covering-indexed-expr branch. (check-in: 9ac67ff9 user: drh tags: covering-indexed-expr)
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)
2022-11-24
20:11
Speed up base85() conversions and sync w/trunk. (check-in: 17b82350 user: larrybr tags: base_convert)
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)
02:59
Speed up base64 conversions, and add test with more data for the baseNN conversion to grind. (check-in: 6c84ae4b user: larrybr tags: base_convert)
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)
2022-11-23
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)
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)
15:52
Remove a bit of over-cleverness which breaks loading of sqlite3.js in some main-thread cases. Broken by [96f76e7616]. (check-in: 220cc4c6 user: stephan tags: trunk)
15:33
OPFS concurrency tester: ensure that the work interval timer does not overlap with the work time. (check-in: 8f207655 user: stephan tags: trunk)
2022-11-22
22:46
Add more baseNN tests, get oversize error trapping working, and sync w/trunk (check-in: 03819e93 user: larrybr tags: base_convert)
20:58
Merge enhancements and fixes from trunk. (check-in: f8932e04 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)
19:04
Add test/basexx1.test to test is_base85(t), base85(x) and base64(x). Sync w/trunk. (check-in: 4e433454 user: larrybr tags: base_convert)
2022-11-21
16:03
Merge trunk into wasi-patches branch to clean up the diff view. (check-in: 95de6742 user: stephan tags: wasi-patches)
16:00
OPFS contention test: give each worker a distinct recognizable name instead of a random one. (check-in: 5f564bf7 user: stephan tags: trunk)
06:07
Add new JS tests dir to those pushed to the test server. (check-in: 07182dca user: stephan tags: trunk)
05:18
More tweaking of OPFS concurrency measures and the related test app. (check-in: a8d4da15 user: stephan tags: trunk)
04:12
Resolve missing SQLITE_LOCKED result code which triggered a new (since last checkin) exception in the OPFS VFS. Improve output of the OPFS contention tester app. (check-in: 2debbbca user: stephan tags: trunk)
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)
2022-11-20
05:47
js dist: account for a file rename in the previous checkin. (check-in: 469f9011 user: stephan tags: trunk)
05:36
Further minor cleanups in the JS build related to vanilla vs ESM. (check-in: 100a5968 user: stephan tags: trunk)
04:14
Remove an obsolete reference to WASMFS from ext/wasm/index.html. (check-in: 51ff6818 user: stephan tags: trunk)
04:14
Generic cleanups and doc additions in the wasm build files. (check-in: d10f385e user: stephan tags: trunk)
04:13
Add 'snapshot' target to create distinctly-named snapshot builds of the wasm deliverables zip file. (check-in: f7620aa0 user: stephan tags: trunk)
01:15
Minor cleanups in the ESM-related preprocessor filtering. (check-in: 205884a2 user: stephan tags: trunk)
2022-11-19
16:16
Get tester1.js working via an ES6 worker module and add that variant to the dist zipfile. (check-in: 90480586 user: stephan tags: trunk)
05:26
Add build of sqlite3.mjs (ES6 module), add a test app for it, and include it in the dist build. (check-in: 2e783670 user: stephan tags: trunk)
02:58
Integrate a custom preprocessor to the JS build process to facilitate creation of both vanilla JS and ES6 Module builds from the same source files. There is still some build-level reworking pending to make an ESM build a first-class deliverable. (check-in: 10c723d9 user: stephan tags: trunk)
02:51
More work towards creation of a ES6 JS module. (Closed-Leaf check-in: 6b826e70 user: stephan tags: js-cpp)
02:39
New extensions for base85 and base64 conversion UDFs (check-in: 5cc1fe1d user: larrybr tags: base_convert)
