| 20:07 | Another reformulation of SQLITE_WASM_DEALLOC to attempt to work around a Safari-specific quirk reported in forum post e5b20e1feb. (check-in: ae0196d8 user: stephan tags: trunk) | |
|
2023-01-01
| ||
| 12:22 | An alternative solution to mapping SQLITE_WASM_DEALLOC to the proper function pointer in JS, to account for a Safari-specific quirk reported in forum post e5b20e1feb. (check-in: 688c5c13 user: stephan tags: trunk) | |

|
2022-12-27
| ||
| 22:46 | Add sqlite3changeset_new/old_js(), which work like sqlite3_preupdate_new/old_js() but on changesets. (check-in: e8afad63 user: stephan tags: trunk) | |
| 14:34 | Expose sqlite3_preupdate_hook() and friends to the JS API. (check-in: cc02783a user: stephan tags: trunk) | |

|
2022-12-26
| ||
| 17:15 | Expose the auto-extension API to JS and reorganize some nearby code. (check-in: 52b229d1 user: stephan tags: trunk) | |
| 15:14 | Fix an infinite loop in the MEMSYS5 auxiliary memory allocator that occurs for memory allocations between 500MiB and 1GB in size. Error introduced by check-in [949133231f8f751a]. The problem only affects builds that include the SQLITE_ENABLE_MEMSYS5 compile-time option. (check-in: 8da0f0c3 user: drh tags: trunk) | |
| 15:08 | Document sqlite3.capi.sqlite3_prepare_v3() as accepting an ArrayBuffer and ensure that it can. (check-in: ae3ae92e user: stephan tags: trunk) | |
| 14:55 | Correct some internal-use JS docs and update the 'string:flexible' type conversion to accept an ArrayBuffer (as it was recently documented to). (check-in: eff5d3be user: stephan tags: trunk) | |
| 14:25 | Only add an on-db-close cleanup entry for collations if adding the collation succeeds and xCompare is-a JS function. (check-in: 18a5480f user: stephan tags: trunk) | |
| 13:45 | Extend [0e69b2c379e618] to support uninstalling stale JS-to-WASM function pointers added on behalf of UDFs. (check-in: 7a46e629 user: stephan tags: trunk) | |
| 13:00 | Add JS infrastructure which enables sqlite3.capi.sqlite3_close_v2() to clean up stale JS-to-WASM collation function conversions installed on behalf of a given db handle. The same for UDF mappings is TODO. (check-in: 0e69b2c3 user: stephan tags: trunk) | |
| 11:13 | Reimplement sqlite3.capi.sqlite3_close_v2() and sqlite3session_delete() as a hand-written bindings so that they can attempt to clean up certain (potentially) FuncPtrAdapter-installed functions before closing. Correct the create-function family of JS-to-function-pointer automated conversions to include the UDF's arity as part of the mapping's key so that (un)binding a UDF to different functions for different arities works (and add tests confirming it). Correct a broken doc link in module-symbols.html. (check-in: 60b262ef user: stephan tags: trunk) | |
| 01:44 | Grammar fixup in comment re SQLITE_TRACE_PROFILE trace event. (check-in: b6dc80cb user: larrybr tags: trunk) | |
|
2022-12-25
| ||
| 23:54 | module-symbols.html: add some missing links to C-side API docs for recently-added JS counterparts. (check-in: 7d4f4e96 user: stephan tags: trunk) | |
| 23:45 | Update JS worker #1 API and related tests for recent API changes. (check-in: d797e183 user: stephan tags: trunk) | |
| 22:55 | Rename the new wasm.irSizeof() to sizeofIR() because that seems clearer. (check-in: 49a83ca3 user: stephan tags: trunk) | |
| 22:49 | Minor internal API doc correction and extend a test for oo1.DB.selectValues(). (check-in: b7295b1c user: stephan tags: trunk) | |
| 22:44 | Add sqlite3.oo1.DB.selectValues(). Correct a logic error which could cause DB.selectValue(), DB.selectArray(), and DB.selectObject() to fail to finalize a statement if a call to bind() failed. Add more session API tests. (check-in: 6adc8a10 user: stephan tags: trunk) | |
| 20:25 | Merge wasm-session-api branch into trunk, adding the session API to the JS/WASM components. (check-in: dfb8b651 user: stephan tags: trunk) | |
| 20:22 | Add basic session API JS tests. (Closed-Leaf check-in: 64e03260 user: stephan tags: wasm-session-api) | |
| 20:05 | Add sqlite3.wasm.irSizeof() and extend certain allocation functions to make use of it. (check-in: 1cbc7b18 user: stephan tags: wasm-session-api) | |
| 17:12 | Add tests confirming that JS sqlite3_exec()'s SQL argument participates in the 'string:flexible' type conversion. (check-in: 926d0c61 user: stephan tags: trunk) | |
| 17:09 | Replace the "manual" implementation of sqlite3.capi.sqlite3_exec() with a briefer "automated" one via the [7f9ace1b11a67] feature addition. Minor code-adjacent internal cleanups. (check-in: 4888957b user: stephan tags: trunk) | |
| 16:20 | Remove duplicated JS binding of sqlite3changeset_apply_v2(). (check-in: 2e8336b6 user: stephan tags: wasm-session-api) | |
| 15:28 | Add the address of the associated db handle to the sqlite3_trace_v2() output originating from sqlite3.oo1.DB's trace flag. (check-in: 0a36568c user: stephan tags: wasm-session-api) | |
| 15:14 | Update the session-related JS bindings to account for today's internal API changes. (check-in: be63944d user: stephan tags: wasm-session-api) | |
| 14:13 | Merge trunk into wasm-session-api branch. (check-in: 7f8f1acd user: stephan tags: wasm-session-api) | |
| 14:04 | Add missing sqlite3_context_db_handle() JS binding. Reimplement sqlite3_set_authorizer() and sqlite3_set_auxdata() JS bindings to take advantage of [7f9ace1b11a67]. Teach FuncPtrAdapter to emit a console.warn() message if it is invoked after the library is bootstrapped, the goal being to inform users that it's an internal API and should not be invoked from client-side code. (check-in: 8e3d4f62 user: stephan tags: trunk) | |
| 12:51 | Enhance sqlite3.wasm.xWrap.FuncPtrAdapter to be able to handle sqlite3_create_function() and friends and reimplement those bindings to use this feature (this will also simplify certain session API bindings). Interal API changes only with no client-side breakage. (check-in: 7f9ace1b user: stephan tags: trunk) | |
| 10:22 | Simplify the signature for JS functions, as opposed to function pointers, passed to sqlite3_exec(), eliminating the superfluous initial two arguments. Update related tests to demonstrate both function-passing approaches. (check-in: e7cc70cd user: stephan tags: trunk) | |
|
2022-12-24
| ||
| 15:34 | Incorporate wasi-sdk RANLIB configure script patch from the VMware OCTO team. (check-in: 478fe96e user: stephan tags: wasi-patches) | |
| 15:31 | Merge trunk into wasi-patches branch. (check-in: 52f40ab1 user: stephan tags: wasi-patches) | |
| 15:28 | Replace JS-side use of SQLITE_TRANSIENT with the new SQLITE_WASM_DEALLOC, reducing the amount allocation/copying required by sqlite3_bind_blob/text() and sqlite3_result_blob/text(). Remove the 'experimental' log message from the virtual table tests. (check-in: ffe2999a user: stephan tags: trunk) | |
| 14:16 | Extend oo1.Stmt.bind() to accept ArrayBuffer instances to bind as blobs. (check-in: f76bd301 user: stephan tags: trunk) | |
| 13:46 | Add a test for the (failure) case of client-level code calling the oo1.Stmt constructor directly. (check-in: 6a37874d user: stephan tags: trunk) | |
| 11:16 | oo1.DB.exec() rowMode="$columnName": a minor optimization and a preemtive fix for a hypothetical corner-case bug. (check-in: 0b2df22b user: stephan tags: trunk) | |
| 01:59 | If sqlite3.oo1.DB.exec()'s callback returns a literal false, stop step()ing over results as if the end of the result set had been reached. Unrelated minor code-adjacent cleanups. (check-in: 33a58c8e user: stephan tags: trunk) | |
|
2022-12-23
| ||
| 23:46 | Reimplement JS's sqlite3_bind_text/blob() with hand-written bindings to permit more flexible inputs. Add automated JS-to-C function conversion to sqlite3_busy_handler(). sqlite3.wasm.xWrap()'s '*' argument conversion no longer treats JS strings as C-strings: those conversions require explicit opt-in via the 'string' converter (or equivalent). (check-in: 96ba4494 user: stephan tags: trunk) | |
| 21:23 | Merge trunk into wasm-session-api branch. (check-in: 6cdb036d user: stephan tags: wasm-session-api) | |
| 21:10 | Internal JS cleanups. Correct part of [ac136925a645] to account for the eTextRep flag being able to hold flags other than the encoding. (check-in: 1dfc03ab user: stephan tags: trunk) | |
| 19:33 | Merge trunk into wasm-session-api branch. (check-in: f1decc83 user: stephan tags: wasm-session-api) | |
| 19:16 | Consolidate/unify how the JS bindings of the create_function/collation family of functions react to a non-UTF8 encoding: they now treat a falsy value as SQLITE_UTF8 and fail with SQLITE_FORMAT for an invalid encoding. (check-in: deffe6fb user: stephan tags: trunk) | |
| 19:11 | Add base64() and base85() to shell sources for the non-configured makefiles, too. (check-in: ac136925 user: larrybr tags: trunk) | |
| 19:04 | Add base64() and base85() text/blob conversions to the CLI. (check-in: 4bc98a2d user: larrybr tags: trunk) | |
| 18:38 | Explicitly omit threading and extension loading from the ext/wasm/c-pp binary build to avoid a link error on some systems. (check-in: 5d9a1471 user: stephan tags: trunk) | |
| 18:25 | Add SQLITE_ENABLE_MATH_FUNCTIONS to the list of feature flags in sqlite3-wasm.c. (check-in: 58503cd1 user: stephan tags: trunk) | |
| 18:19 | Cherry-pick [c4dab53b8ea3401abd] for sqlite3.wasm.xWrap() optimizations. (check-in: 9b97412d user: stephan tags: trunk) | |
| 18:14 | Internal cleanups and minor speed optimizations in the sqlite3.wasm.xWrap() infrastructure. (check-in: c4dab53b user: stephan tags: wasm-session-api) | |
| 14:49 | Fix lots of harmless, nuisance compiler warnings, mostly unused parameter warnings in extensions. (check-in: c14bbe16 user: drh tags: trunk) | |
| 14:11 | Add sqlite3.capi JS bindings for the sqlite3session_...(), sqlite3changeset_...() and sqlite3changegroup_...() APIs, noting that they are completely untested. Aside from missing tests, these bindings reveal a slight string-argument-type shortcoming in the callback function pointer "reverse binding" which should ideally be resolved before publishing them. (check-in: 0a39172e user: stephan tags: wasm-session-api) | |
| 11:46 | Additional fixes for yet more completely harmless compiler warnings. (check-in: 7d3772f0 user: drh tags: trunk) | |
| 11:46 | Initial pieces for binding the session API to JS. Far from complete. See forum post 210e36a1e3 for the discussion. (check-in: cd8c1008 user: stephan tags: wasm-session-api) | |
| 11:32 | Squelch a new (and, in this case, harmless) compiler warning. (check-in: a02e19dd user: stephan tags: trunk) | |

| 21:32 | Asserts added to ensure that the iCompare variable in the bytecode engine is correctly initialized before it is used. (check-in: 7b5900a1 user: drh tags: trunk) | |
| 19:12 | Avoid having to reinitialize Vdbe.pResultRow upon each call to sqlite3_step() for a small size reduction and performance increase. (check-in: 6a00d67f user: drh tags: trunk) | |
| 18:44 | Rename the Vdbe.pResultSet field to pResultRow in order to better distinguish it from other variables with similar names. (check-in: 1fd6211e user: drh tags: trunk) | |
| 18:35 | Small performance optimization associated with shared cache in the byte-code engine. (check-in: 3181331c user: drh tags: trunk) | |
| 17:36 | Small performance optimization on the OP_Insert opcode. (check-in: 781fdcb9 user: drh tags: trunk) | |
| 10:53 | sessionfuzz.c: use lt/gt brackets instead of double-quotes when #including zlib.h, as reported in forum post 91a104bd65. (check-in: 7d7780c3 user: stephan tags: trunk) | |

| 21:01 | Merge the latest trunk enhancements into the reuse-schema branch. (check-in: 1bfae9b3 user: drh tags: reuse-schema) | |
| 19:11 | More efficient implementation of large precisions on the "%c" format for the built-in printf(). This is an effort to avoid a reported timeout on a (ridiculous) query generated by OSSFuzz. (check-in: 371f9b88 user: drh tags: trunk) | |
| 18:28 | Sync w/trunk prior to branch-purpose changes. (Leaf check-in: ae8f623f user: larrybr tags: extension_opts) | |
| 14:13 | Ensure that the expression of a virtual column really is an expression and not just a reference to another column, as a real expression is necessary for the indexed expression coverage optimization to work properly. Forum thread 07b36e3899a9ae21. (check-in: 40549bac user: drh tags: trunk) | |
| 12:18 | New WHERETRACE entries for adding and removing objects from the Parse.pIdxEpr list as part of indexed expression coverage. Debug and testing changes only - no affect on production builds. (check-in: 4dc438a9 user: drh tags: trunk) | |
|
2022-12-20

| 15:22 | Add about 150 new fuzzer cases to test/fuzzdata8.db. (check-in: a8d8d9cd user: drh tags: trunk) | |
| 15:02 | Add ALWAYS() to always-true branches in the locking logic of the memdb VFS. (check-in: 01fa7602 user: drh tags: trunk) | |
| 14:02 | Improvement to the dbsqlfuzz fix of [f113eebdbe68246f]. (check-in: 79d62956 user: drh tags: trunk) | |
| 01:48 | Do not use indexed expressions to replace the expression being indexed on a RIGHT JOIN as that leads to problems, as shown by dbsqlfuzz a644e70d7683a7ca59c71861a153c1dccf8850b9. (check-in: f113eebd user: drh tags: trunk) | |

| 14:46 | Minor sed script tweak in the wasm GNUmakefile for BSD portability, as reported in forum post 4a97813fcbd4f63e. (check-in: 49efcf6d user: stephan tags: trunk) | |
| 14:43 | Update test-opfs-vfs.js to account for recent API changes. Reported in forum post 4a97813fcbd4f63e. (check-in: 2a636746 user: stephan tags: trunk) | |
| 14:06 | Fix an assert() in fts5. Simplify memdb xLock/xUnlock some. (check-in: 7fe158aa user: dan tags: trunk) | |

| 12:49 | Add NEVER/ALWAYS to branches that have become unreachable due to recent enhancements. (check-in: b4281db4 user: drh tags: trunk) | |
| 11:14 | Update wasmfs.make to get WASMFS building again, but changes made to OPFS-over-WASMFS since we last tested it have made it incompatible with how we used it. It can now only be used from worker threads, eliminating the one benefit it had over the sqlite3_vfs OPFS implementation. Remove/amend references to WASMFS in the docs and remove all WASMFS-specific test app links from index.html. (check-in: 32dc98c8 user: stephan tags: trunk) | |

| 18:32 | Disallow some of the query invariant tests on SQL statements that contain a GROUP BY since output terms that are no covered by the GROUP BY are indeterminant. (check-in: 28ba1fec user: drh tags: trunk) | |
| 13:04 | Expose a JS-friendly subset of sqlite3_config() to JS, with the notable caveats that (1) setting up the JS bindings requires starting the library, making sqlite3_config() illegal to call and (2) calling sqlite3_shutdown() in order to make it legal to call sqlite3_config() may undo certain JS-side library initialization. Move sqlite3_(de)serialize() into the int64-mode-only bindings because of their int64 args. (check-in: 62e0c931 user: stephan tags: trunk) | |

| 20:03 | Create a new affinity called FLEXNUM that works like NUMERIC except that it never tries to convert integer to real or real to integer. The affinity is only used internally - it is not possible to create a table column with this affinity. This affinity is used on subqueries and views that are built off of a compound SELECT and where the datatype is controlled by a CAST expression. dbsqlfuzz c9ee6f9a0a8b8fefb02cf69de2a8b67ca39525c8 (check-in: 44135d6e user: drh tags: trunk) | |

| 15:37 | Omit the columnTypeImpl() function from the build when SQLITE_OMIT_DECLTYPE is defined, because it is no longer used in that case. (check-in: 751e344f user: drh tags: trunk) | |
| 13:45 | Fix harmless compiler warnings. (check-in: ddb260cc user: drh tags: trunk) | |

| 18:06 | Rename the new peek/pokeF32() and peek/pokeF64() to peek/poke32f() and peek/poke64f() for consistency with related APIs and because they're easier on both the eyes and the fingers. (check-in: cc86f03e user: stephan tags: trunk) | |
| 17:52 | Merge all the latest trunk enhancements into the coroutines-exp2 enhancement branch. (Closed-Leaf check-in: ea278438 user: drh tags: coroutines-exp2) | |
| 17:46 | Rework the code that computes the datatypes and affinities for subqueries and views. If the subquery/view is constructed from a compound SELECT where the affinity varies across arms of the compound, set the affinity for the corresponding column in the constructed view to be BLOB so that it is allowed to take on any data type. (check-in: 27655c93 user: drh tags: trunk) | |
| 16:40 | Slight reformulation of some test code to test multi-arg wasm.peek() call form. (check-in: 349bb28f user: stephan tags: trunk) | |
| 14:41 | If the SELECT that implements a subquery or a VIEW or a CREATE TABLE AS is a compound with different result datatypes on two or more arms of the compound, then the overall column type becomes BLOB (ANY). (Closed-Leaf check-in: 6ebb178c user: drh tags: refactor-subquery-types) | |
| 14:40 | Use the new peek/poke() variants throughout tester1.js. (check-in: ef7b7835 user: stephan tags: trunk) | |
| 14:28 | Add convenience variants of sqlite3.wasm.peek/poke() for each numeric type to help reduce errors related to typos in the final argument (type-name strings). If wasm.xWrap.FuncPtrAdapter is called as a function, instead of a constructor, it now behaves as if it were called as a constructor (previously it threw an exception). (check-in: 14e3fc01 user: stephan tags: trunk) | |
| 09:06 | Back out the part of the change in [88a05141c28e5ff1] that adds affinity to the materialization of a view, as the affinity can be undefined for a compound query. This passes all TCL tests, but shows failures in the TH3 tests derived from forum post 6f842bc5b2dadcb2, presumably because the WHERE clause of the query uses constraints of the form "source_crs_code='8675'" instead of "source_crs_code=8675". Perhaps further changes on this branch should reimplement affinity on joins in cases where the affinity is unambiguous. (check-in: fe5a77bc user: drh tags: refactor-subquery-types) | |
| 08:12 | Add a test to demonstrate/verify which object acts as "this" in a oo1.DB.exec() callback. (check-in: 8fc4b3f1 user: stephan tags: trunk) | |
| 08:01 | A micro-optimization in sqlite3.oo1.DB.exec(). Changed the rowMode option of that method to only accept $X instead of $X, @X, and :X, as the extra options are entirely superfluous and may lead to confusion. (check-in: 82a6c7fd user: stephan tags: trunk) | |

| 21:22 | Further fix for ticket [57c47526c34f01e8]. If a subquery has a result set column of the form "CAST(expr AS NUMERIC)" do not give that column NUMERIC affinity. NUMERIC affinity always goes to an integer if able, but a CAST to numeric is a no-op if the input is a number. So the two are not equivalent. (check-in: f0325359 user: drh tags: trunk) | |
| 18:58 | If a subquery has a result column of the form "CAST(... AS NUMERIC)" then give that column no affinity rather than NUMERIC affinity. This is because casting to numeric preserves real values that could be integers but numeric affinity does not. By using no affinity on the column, we make the behavior consistent if the subquery is implemented as a co-routine or is materialized. (Closed-Leaf check-in: ece07d09 user: drh tags: cast-to-numeric) | |
| 18:42 | Revert part of [9386d6f63468] because the new automatic function pointer binding cannot properly track per-context function mappings when the context is more complex than a single context-type pointer. e.g. it is fine for sqlite3_trace_v2() but it breaks down with sqlite3_create_collation() because that one needs to use the collation name as part of the context key and we cannot sensibly do so with the current code.

| 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) | |

| 20:32 | Enhance the sqlite3_stmt_scanstatus() API and add sqlite3_stmt_scanstatus_v2(). For creation of easier to read query performance reports. (check-in: 55800833 user: dan tags: scanstatus_v2) | |
| 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) | |

| 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) | |

| 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) | |

| 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) | |

| 06:09 | 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) | |
