| 18:11 | Make the UPDATE method of the sqlite_dbpage virtual table rebust against OOM errors. Forum post bbcf0dd6ca. Test case in TH3. (Leaf check-in: 852f2c9583 user: drh tags: branch-3.39) | |
| 18:04 | Extra OOM check in shell_error_context() of the CLI. forum post 5708841db0. (check-in: d6893183c2 user: drh tags: branch-3.39) | |
| 18:01 | Make the UPDATE method of the sqlite_dbpage virtual table rebust against OOM errors. Forum post bbcf0dd6ca. Test case in TH3. (check-in: d15c9a4a32 user: drh tags: trunk) | |
| 13:50 | Worker1: use a list, rather than a single slot, to manage the default db link so that we can keep the least-recently-opened db as the default. Re-introduce worker1.export() but do not yet expose it until an equivalent import() (or open() option) is implemented. (check-in: c7750c101d user: stephan tags: trunk) | |
| 11:53 | Internal tweaks to the OPFS VFS result codes. (check-in: 32e1a2d2eb user: stephan tags: trunk) | |
| 11:09 | Add oo1.DB.exec() 'returnValue' option, which specifies what exec() should return. Defaults to the db object and enables direct return of the result rows array or a list of the individual SQL statements. Other code-adjacent internal cleanups. (check-in: 69d36a6aa5 user: stephan tags: trunk) | |
| 10:53 | Avoid a segfault that could occur when running the recover API on a database handle with memory-mapping enabled. (check-in: e02c697281 user: dan tags: trunk) | |
| 01:22 | Extra OOM check in shell_error_context() of the CLI. forum post 5708841db0. (check-in: cb12ac5de1 user: drh tags: trunk) | |
|
2022-10-30
| ||
| 11:39 | Add oo1.DB.selectArray() and selectObject(). (check-in: 7660db2a2e user: stephan tags: trunk) | |
| 11:22 | Refactoring towards being able to distinguish locking-related errors from non-locking errors in OPFS VFS operations. On a branch because it's not yet clear whether this is a misuse of the SQLITE_IOERR_... codes. Edit: indeed, this is a misuse of the result codes. (Closed-Leaf check-in: 646fe2ce87 user: stephan tags: opfs-locking-result-codes) | |
| 10:24 | Adjust automatic OPFS locking retries such that they will wait up to a total of 3 seconds spanning 4 attempts. (check-in: bbce49d81a user: stephan tags: trunk) | |
| 09:47 | Minor WASM build cleanups. Enable custom Module.instantiateWasm() when not in WASMFS mode (where it doesn't work). Add sqlite3.debugModule URL param to enable some module-init-time debugging output. (check-in: 50f678846a user: stephan tags: trunk) | |
| 08:39 | Reduce wasm module's starting memory from 128mb to 16mb. The latter value is needed only for WASMFS-based batch-runner.js, as WASMFS builds cannot be configured for dynamic memory growth without a tremendous performance hit. (check-in: ed9d93c487 user: stephan tags: trunk) | |
| 07:01 | Minor updates to the Windows batch tools. (check-in: b42f56205f user: mistachkin tags: trunk) | |
|
2022-10-29
| ||
| 12:31 | Update ext/wasm/README.md for recent developments. (check-in: c76ec31ebf user: stephan tags: trunk) | |
| 10:14 | More styling of module-symbols.html. (check-in: a36f42a836 user: stephan tags: trunk) | |
| 09:45 | Expand and document the wasm doc-update make rules. Extend the dist rules to fail more readily if there's a problem. (check-in: 362ec11ec0 user: stephan tags: trunk) | |
| 07:54 | Move the sqlite3.capi.wasm namespace to sqlite3.wasm. This causes a tiny bit of naming confusion with the sqlite3.wasm *file*, but seems to make more sense than having it as a sub-namespace of capi. (check-in: 3f16eb18d6 user: stephan tags: trunk) | |
|
2022-10-28
| ||
| 18:52 | Fix harmless compiler warnings in testing code. (check-in: 2f53612388 user: drh tags: trunk) | |
| 18:35 | Add sqlite3recover() support to fuzzcheck. (check-in: e65c5bdc5b user: drh tags: trunk) | |
| 14:33 | Remove sqlite3_interrupt() from the WASM build, as it is essentially impossible to employ in JS's threading model. (check-in: e853875900 user: stephan tags: trunk) | |
| 11:40 | Add ext/wasm/module-symbols.html. Adjacent minor JS touchups. (check-in: 24f12e681e user: stephan tags: trunk) | |
| 10:36 | Minor sqlite3.oo1 API reorg prompted by documenting. (check-in: 55237924ca user: stephan tags: trunk) | |
|
2022-10-27
| ||
| 23:17 | Fix a minor problem with sqlite_dbdata. (check-in: 58c2e49279 user: drh tags: trunk) | |
| 20:27 | Fix another crash in the recover extension triggered by a corrupt database. (check-in: d125377378 user: dan tags: trunk) | |
| 19:06 | Fix another problem to do with recovering from in-memory databases. (check-in: 5a7bfd4a21 user: dan tags: trunk) | |
| 19:02 | Ensure that the VFS wrapper in the recover extension does not attempt to invoke undefined methods on the underlying VFS. (check-in: 347c575108 user: dan tags: trunk) | |
| 18:35 | Fix an assert() failure in the recover extension triggered by a zero value as the first page-number in an overflow page chain. (check-in: 44c0874c33 user: dan tags: trunk) | |
| 18:20 | In the CLI, ensure that input to utf8_width_print is not NULL, or if it is, change it to an empty string. For for the problem reported by forum post 2961cf13eec61876. (check-in: 9ecc9d25ea user: drh tags: trunk) | |
| 18:19 | Change the name of the ".recover" command option "--freelist-corrupt" to "--ignore-freelist". (check-in: afce8443ac user: dan tags: trunk) | |
| 14:41 | speedtest1.html: when vfs==kvvfs, increase --size from 2 to 4, as enabled by [a4d40f6346e7]. --size 5 is 4.96mb out of (supposedly) 5mb, which works but is a bit too close to the edge. (check-in: a608d584a8 user: stephan tags: trunk) | |
| 14:28 | Automatically set temp_store=MEMORY if the VFS is kvvfs. (check-in: a4d40f6346 user: drh tags: trunk) | |
| 14:00 | Do not accept a NULL pointer for the filename in KVVFS. (check-in: fdecbd3b5b user: drh tags: trunk) | |
| 12:46 | The kvvfs VFS should remember the page size when writing to the database. (check-in: fc5503c8ac user: drh tags: trunk) | |
| 11:32 | Re-enable the .recovery and .dbinfo commands in shell.c.in in the fiddle build, as those were fixed by [3d20d77a3511] and [cd0aa27d1732]. (check-in: ba3a7a4a99 user: stephan tags: trunk) | |
| 11:25 | Do not use sqlite3_result_text16() in the recover extension if SQLITE_OMIT_UTF16 is defined. (check-in: 3d20d77a35 user: dan tags: trunk) | |
| 11:12 | Fix a problem with running ".recover" on an in-memory database. (check-in: 87b4cca2b8 user: dan tags: trunk) | |
| 10:51 | Do not use sqlite3_mutex_xxx() functions in sqlite3recover.c when built with SQLITE_THREADSAFE=0. (check-in: cd0aa27d17 user: dan tags: trunk) | |
| 03:57 | Minor doc typo fixes. (check-in: ed8d3f25a4 user: stephan tags: trunk) | |
| 03:56 | Restructure and simplify the feature-detection #defines of the recovery support in shell.c.in and disable it when building fiddle because it uses features we elide from the wasm build (e.g. utf16), leading to link errors. (check-in: ddd10c05c5 user: stephan tags: trunk) | |
| 03:03 | Expose sqlite3_randomness() to WASM and add a custom binding for it which can populate a JS byte array. Add WhWasmUtil.isPtr(). (check-in: 333e67076b user: stephan tags: trunk) | |
|
2022-10-26
| ||
| 21:14 | Disable the push-down optimization for sub-queries that are INTERSECT, UNION or EXCEPT compounds. dbsqlfuzz a34f455c91ad75a0cf8cd9476841903f42930a7a. This corrects an issue that was introduce 12 days earlier by [ed14863dd72e35fa]. (check-in: 346a3b12b8 user: dan tags: trunk) | |
| 20:12 | Remove an unused variable from the recovery extension. (check-in: a029dddff4 user: drh tags: trunk) | |
| 18:41 | Add the "recover" extension in ext/recover/, for salvaging data from corrupt databases. (check-in: a820792548 user: dan tags: trunk) | |
| 18:29 | Remove an undefined left-shift operation from the recover extension. (Leaf check-in: a67082357a user: dan tags: recover-extension) | |
| 18:22 | Merge further changes from trunk, including fix to dbdata.c. (check-in: bcf6b48d52 user: dan tags: recover-extension) | |
| 18:04 | Make the shell .recover command and the dbdata.c module more robust in the face of corrupted databases. (check-in: 4eef562a00 user: dan tags: trunk) | |
| 15:40 | Correct misuse of localhost-mode-only symbol S in fiddle-worker.js, which should fix the outage reported in forum post 67d985ac0bbe407f. (check-in: 3b5aa50c22 user: stephan tags: trunk) | |
| 15:34 | Corrected link to fiddle in ext/wasm/index.html (broken by [3d7b4f36b7dd]). (check-in: 6efa0bae16 user: stephan tags: trunk) | |
| 11:27 | Replace the newly-removed oo1.DB.getFilename() with DB.dbFilename() with the hope that the distinction from the dbInstance.filename property is clearer. (check-in: 0b80543d75 user: stephan tags: trunk) | |
| 11:12 | Remove oo1.DB.hasFilename() and getFilename(), as they are unnecessary. (check-in: 75c546b982 user: stephan tags: trunk) | |
| 11:11 | Remove the sqlite3StdTypeMap global constant that was made obsolete by [aa6e908619624867]. (check-in: 3dfdfb3f12 user: drh tags: trunk) | |
| 06:05 | Add --download-version flag to ext/wasm/version-info.c and correct dist target's output version format to match. (check-in: 6f2a40d06d user: stephan tags: trunk) | |
|
2022-10-25
| ||
| 16:57 | Add doc page link to the wasm dist README.txt. (check-in: c2380668d9 user: stephan tags: trunk) | |
| 16:04 | Correct -O level for fiddle build when built from the top-most directory (-Os instead of -O0). (check-in: ff4fc29c38 user: stephan tags: trunk) | |
| 15:59 | Rename fiddle.html to index.html and move fiddle push-to-server rules from GNUmakefile into fiddle.make. (check-in: 3d7b4f36b7 user: stephan tags: trunk) | |
| 15:38 | speedtest1: use the current (or default) vfs->xDelete method to unlink the db. This is specifically necessary when running the opfs vfs in a wasm build of speedtest1. This worked without this fix until recently because the affected test code was performing similar acrobatics in its stead. (check-in: d3c830bd37 user: stephan tags: trunk) | |
| 13:46 | Fix the ".dump" command in the CLI so that it is more rebust against corrupt database files. At the same time, enhance the sqlite3_strglob() and sqlite3_strlike() interfaces so that they will do sensible things with NULL string pointers. (check-in: 681c85ef69 user: drh tags: branch-3.39) | |
| 13:44 | Enhance the sqlite3_strglob() and sqlite3_strlike() interfaces so that they will do sensible things with NULL string pointers. This is an extra layer of defense against bugs such as reported by forum post 730b554179. (check-in: 8ba9c884bd user: drh tags: trunk) | |
| 13:42 | Make the ".dump" command of the CLI more robust against malformed databases. See forum post 730b554179. (check-in: 0573edfb9e user: drh tags: trunk) | |
| 11:05 | Merge latest trunk changes with this branch. (check-in: 757e3f5859 user: dan tags: recover-extension) | |
| 08:41 | Minor doc tweaks in the JS GNUmakefile. (check-in: 9c8df130b8 user: stephan tags: trunk) | |
| 08:15 | Remove persistence from the 'reverse log order?' checkbox in tester1.js to eliminate an inconsistency between the main-thread and worker-thread modes (the latter having no option for persistence of that setting). (check-in: ecf906b07f user: stephan tags: trunk) | |
| 08:06 | Minor cleanups and doc improvements in the OPFS sqlite3_vfs proxy. (check-in: 48645f7bca user: stephan tags: trunk) | |
|
2022-10-24
| ||
| 21:58 | This check-in attempts to make the SrcItem object smaller by combining the zDatabase and pSchema fields into a single union. It mostly works, but there are some issues, and the performance savings is minimal. So it is side-tracked onto this dead-end branch. (Closed-Leaf check-in: 80fbb30f28 user: drh tags: failed-opt-attempt) | |
| 18:42 | Fix typo in comment. (check-in: f65c95658f user: drh tags: trunk) | |
| 18:33 | Add a comment to a previously undescribed member of the Walker union. (check-in: 69d704224e user: drh tags: trunk) | |
| 15:51 | Use the same "PRAGMA synchronous" setting for the output of a "VACUUM INTO" as are configured for the database being vacuumed. (check-in: 86cb21ca12 user: dan tags: trunk) | |
| 13:50 | Improve the ability of the query planner to recognize covering indexes even on tables with more than 63 columns and where the index is over columns beyond the 63rd column. (check-in: 3d1992de47 user: drh tags: branch-3.28) | |
| 13:20 | Improve the ability of the query planner to recognize covering indexes even on tables with more than 63 columns and where the index is over columns beyond the 63rd column. (check-in: f058773e41 user: drh tags: trunk) | |
| 12:38 | Update the fuzzinvariant logic in fuzzcheck to the latest code from dbsqlfuzz. (check-in: 739ad58476 user: drh tags: trunk) | |
| 11:10 | Fix built-in documentation for the ".mode qbox" command in the CLI. (check-in: 3d7ea33be1 user: drh tags: trunk) | |
| 11:02 | Test cases for covering indexes on wide tables. (Closed-Leaf check-in: 64c3777eb3 user: drh tags: covering-index-enh) | |
|
2022-10-23
| ||
| 20:09 | The wide-table covering index detection must take into account aggregate queries. (check-in: 9ac73f83c5 user: drh tags: covering-index-enh) | |
|
2022-10-22
| ||
| 23:09 | More frequently send the complete SELECT statement into sqlite3WhereBegin() so that it can more accurately determine index coverage. (check-in: f6d09c5a0d user: drh tags: covering-index-enh) | |
| 20:13 | Enhance the query planner with the ability to discern when an index is covering even when it indexes columns well beyond the 63rd column. (check-in: 1390417be4 user: drh tags: covering-index-enh) | |
| 14:16 | This branch attempts to improve the detection of covering indexes. This first check-in merely improves a parameter name to sqlite3WhereBegin() to be more descriptive of what it contains, and ensures that a subroutine is not inlines so that sqlite3WhereBegin() runs slightly faster. (check-in: cadf5f6bb1 user: drh tags: covering-index-enh) | |
| 13:49 | Clarification on the meaning of SrcList and SrcItem and especially the SrcItem.colUsed and Index.colNotIdxed fields. Comment changes only - no changes to code. (check-in: d96f6cc847 user: drh tags: trunk) | |
|
2022-10-21
| ||
| 20:12 | Begin transitioning the fixed-length (64-bit) bitmap used to keep track of the subset of columns of a table that are used by a query into a more general structure that can work with wide tables. Experimental. (Closed-Leaf check-in: 5dd7858820 user: drh tags: column-set) | |
| 17:48 | Add SQLITE_DQS to the compileoptions_used list, per request in forum post 8b1060122b. Force DQS=0 in sqlite3-wasm.c. (check-in: fcd9e0dbe3 user: stephan tags: trunk) | |
| 17:37 | Macro name typo fix in OS_KV builds. (check-in: 9cf1142b0c user: stephan tags: trunk) | |
| 17:18 | Ensure that the RtreeCell object in rtreeUpdate has all bytes initialized. (check-in: 1e38742bde user: drh tags: trunk) | |
| 06:58 | Add kvvfs tests to tester1.js. Fix a scopedAlloc() misuse in oo1.DB ctor caused by refactoring earlier this morning (and caught by these new tests). (check-in: 8e0f001ab7 user: stephan tags: trunk) | |
| 06:26 | Add timing info and OPFS sanity tests to tester1.js (check-in: 99915b0076 user: stephan tags: trunk) | |
| 05:27 | Expose sqlite3_vfs_unregister() to WASM and unregister kvvfs in Worker threads to avoid its unintended use there (in contexts other than local/sessionStorage). Correct registration of window functions, extend oo1.DB.createFunction() to support window functions, and add window function tests to tester1.js. Correct an incorrect 1-arg handling case for DB.exec(). Add per-test assertion counts to tester1.js. (check-in: f07ce15479 user: stephan tags: trunk) | |
|
2022-10-20
| ||
| 23:48 | Make semantics for UDF xFinal() result handling and error reporting handling more flexible. (check-in: 89f3e1982e user: stephan tags: trunk) | |
| 21:28 | Add more JS tests. Flesh out the aggregate UDF tests to use sqlite3_aggregate_context() so that they can each be used multiple times in the same statement. Add sqlite3_js_aggregate_context() convenience helper. (check-in: 9d034ef5e1 user: stephan tags: trunk) | |
| 18:58 | Apply magic.txt correction and addition reported in forum post 2d2366a04a0385. (check-in: 9bf26e2aa3 user: stephan tags: trunk) | |
| 18:31 | Rename sqlite3_web_... to sqlite3_js_... Document the worker1.close.unlink option. Fix unlink usage in speedtest1.html. Minor JS build cleanups. (check-in: ac9af71b72 user: stephan tags: trunk) | |
| 16:30 | Add a bit to the optimization disabling mask for the indexed expression optimization. (check-in: 56df1482ab user: drh tags: trunk) | |
| 16:22 | Add test case for previous commit. (check-in: 535867a9c8 user: dan tags: trunk) | |
| 16:12 | Only enable the bMaybeNullRow flag on IndexedExpr for an index on an expression, not on a virtual column. But do enable it for the right operand of a right join. (check-in: a9657c87c5 user: drh tags: trunk) | |
| 13:36 | The generalized indexed expression optimization of [2435112867fbd7b6] makes the prior [a47efb7c8520a011] enhancement from 2017 obsolete. This check-in removes the older optimization. (check-in: 56442c9bdd user: drh tags: trunk) | |
| 10:46 | Fix minor problems in test1.c test code. (check-in: 6e545e2b84 user: dan tags: trunk) | |
| 05:14 | Rework sqlite3_wasm_vfs_unlink(), add sqlite3_wasm_db_vfs(), update some docs. (check-in: cdd46858f0 user: stephan tags: trunk) | |
| 04:00 | Minor internal JS cleanups. (check-in: 818ef0b5c9 user: stephan tags: trunk) | |

| 18:04 | In the CLI, never use strcmp() or strncmp() directly. Instead use wrapper functions cli_strcmp() and cli_strncmp() that work correctly even if the input is a NULL pointer. Forum post 142b868da7560d0b. (check-in: 7450a561f8 user: drh tags: trunk) | |
| 18:03 | Move file /ext/misc/dbdata.c to the /ext/recover/ directory. (check-in: f6d5ac807e user: dan tags: recover-extension) | |
| 11:58 | Fix references to "SrcList_item" in comments as that object has since [bfd5bf2c73110fcb] (2021-02-21) been called "SrcItem". Comment changes only. No changes to code. (check-in: e3648a07f5 user: drh tags: trunk) | |
| 11:22 | If a query uses an index where one or more of the columns of the index is an expression and if the corresponding expression is used elsewhere in the query, then strive to read the value of the expression out of the index, rather than recomputing it. This is the "Indexed Expression Optimizations". (check-in: 3da1032878 user: drh tags: branch-3.28) | |
| 10:56 | If a query uses an index where one or more of the columns of the index is an expression or a virtual column, and if the corresponding expression is used elsewhere in the query, then strive to read the value of the expression out of the index, rather than recomputing it. This is the "Indexed Expression Optimizations". (check-in: 2435112867 user: drh tags: trunk) | |
| 07:51 | Update the wasm/js 'push' rule to account for this morning's changes. (check-in: c4a0f745fb user: stephan tags: trunk) | |
| 07:34 | Rename several demo/test files and include more of them in the end-user dist archive. (check-in: 9c85835f6f user: stephan tags: trunk) | |
| 06:14 | Minor wasm/js build tweaks. (check-in: bcbee1ec01 user: stephan tags: trunk) | |
| 06:06 | Update the dist rules for this evening's js/wasm build changes and include an index.html specifically for the subset of apps included in the dist archive. (check-in: a0ef0f32e9 user: stephan tags: trunk) | |
| 04:44 | Apply considerable acrobatics to get the JS/WASM deliverables building to and loadable from a directory other than the one which contains the app-level code. Requires an only-slightly-leaky abstraction of passing a URL argument when loading sqlite3.js but provides much greater flexibility in where the JS/WASM files are located. (check-in: 6d468dab9e user: stephan tags: trunk) | |
| 01:07 | Considerable wasm/js build cleanups and reworking. Remove wasmfs builds from the end-user deliverables and disable the wasmfs build by default, per /chat discussion, as it doubles our deliverable count for only marginal gain. Attempt to move the sqlite3.js/wasm files into subdirectories but rediscovered that that breaks loading in Worker mode because URI resolution of the wasm files differs depending on whether the main script is loaded from a script tag or a Worker.

| 16:47 | Fix the indexed expression resolver for generated columns so that it picks the correct table in a self-join. (check-in: 54c3eb085a user: drh tags: index-expr-opt) | |
| 16:32 | Merge recent trunk fixes into the index-expr-opt branch. (check-in: 6198ab4b87 user: drh tags: index-expr-opt) | |
| 15:02 | Add new test file windowE.test, to test the window functions modules response to an inconsistent collation sequence. (check-in: 740a2eb092 user: dan tags: trunk) | |
