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)
10:50
Remove obsolete "experimental" comments on the virtual-table interface documentation in sqlite.h.in. (check-in: 28fc32ab user: drh tags: trunk)

Improved query planner cost estimates. Fix for ticket [e8b674241947eb3b]. (check-in: 1b779afa user: drh tags: trunk)
02:42
Use the smaller estimated row size for searching IPK tables, but use the original larger row size estimate for scanning, since the leaves can have large rows. (Closed-Leaf check-in: df381899 user: drh tags: qp-tuning)
2022-12-04
23:20
Fix safe mode authorizer callback to reject disallowed UDFs. Reported at Forum post 07beac8056151b2f. (check-in: cefc0324 user: larrybr tags: trunk)

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)
13:05
Doc typo fix for SQLITE_MAX_ALLOCATION_SIZE in malloc.c. No code changes. (check-in: ed1ed212 user: stephan tags: trunk)
11:51
Move kvvfs xRead()/xWrite() buffer from function-local stack memory to heap memory to accommodate changes in emsdk 3.1.27. (check-in: f1da3241 user: stephan tags: trunk)
11:16

00:52
Tuning the query planner by adjusting the weights that predict the relative performance of sorting and index lookup. (check-in: 9f2806da user: drh tags: qp-tuning)
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)
17:52
For the sqlite3_bind and sqlite3_result interfaces for UTF16 strings, round the number of bytes down to the next even number, to avoid creating a UTF16 string that is an odd number of bytes. Forum post 411199488d065f83. (check-in: b57e3c3d user: drh tags: trunk)
15:31
Use sqlite3_result_int64() instead of sqlite3_result_int() when returning potentially large values from the DBSTAT virtual table, to avoid integer overflows in the result. Forum post ada2ab044f. (check-in: 5652154a user: drh 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)
03:35
Experimental branch for more flexible selection of extensions and localization of details of incorporation by host. A WIP for now. (check-in: 98be19ba user: larrybr tags: extension_opts)
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
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)
13:44
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)
