06:52
wasm: add a makefile comment about the static sqlite3.h/c version info injected into the JS files possibly differing from the runtime-emited version info when a user provides their own sqlite3.c. (Leaf check-in: d99a01a0 user: stephan tags: trunk)
2024-04-24
16:36
If a RETURNING clause contains a subquery that references the table that is being updated in the statement that includes the RETURNING clause, then mark the subquery as correlated sot hat it is recomputed for each result and not just computed once and reused. See forum post 2c83569ce8945d39. (check-in: 9ea6bcc8 user: drh tags: trunk)
14:18
Fix a case where a corrupt stat4 record could go unrecognized due to integer overflow. (check-in: 240a4a48 user: dan tags: trunk)
11:51
Add comments linking the assert() added in [cef4d9e3ba586735] to the places where the precondition that the assert() tests are actually required. (check-in: 6f0e7e19 user: drh tags: trunk)
11:40
Avoid slowdown when exprNodeIsConstant() is called on deeply nested SQL functions. (check-in: 1c0b0345 user: dan tags: trunk)
11:21
Ensure that temporary SrcItem objects created by trigger processing have either SrcItem.zName or SrcItem.pSelect defined. Every SrcItem should have one or the other. (check-in: cef4d9e3 user: drh tags: trunk)
06:43
Remove an undocumented feature from the JS Worker1.open API because it relies on broken behavior which has no VFS-agnostic workaround. (check-in: 3a640038 user: stephan tags: trunk)
2024-04-23
12:02
Fix a problem with vector IN operators used with an index where the affinities and collations for the various vector terms are different. (check-in: 86e8c782 user: drh tags: trunk)
06:49
Remove some dead WASM-side code. (check-in: 0a07ee27 user: stephan tags: trunk)
06:36
Minor touchups in JS docs and exception messages. (check-in: 9e7fc937 user: stephan tags: trunk)
05:38
When running the 'dist' target in ext/wasm for an SEE-capable build, ensure that the resulting zip file and directory name include '-see'. (check-in: 04c552b1 user: stephan tags: trunk)
2024-04-22
20:09
Add extra tests for aborting conflicts in the sessions module. (check-in: b4a6d326 user: dan tags: trunk)
17:03
Minor cleanups to [8fbda563d2f5]. (check-in: 5ee2594b user: stephan tags: trunk)
16:46
Extend the JS/WASM SEE build support by (A) filtering SEE-related bits out of the JS when not building with SEE and (B) accepting an optional key/textkey/hexkey option to the sqlite3.oo1.DB and subclass constructors to create/open SEE-encrypted databases with. Demonstrate SEE in the test app using the kvvfs. This obviates the changes made in [5c505ee8a7]. (check-in: 8fbda563 user: stephan tags: trunk)
13:31
Extra robustness in the code that causes cursors to return NULL when they are participating in an OUTER JOIN. (check-in: 672c2869 user: drh tags: trunk)
11:48
For sqlite3.oo1.DB JavaScript classes, bypass execution of any on-open() SQL in SEE-capable builds because it would necessarily run before the client has an opportunity to provide their decryption key, which would leave the db handle in an unusable state and cause the ctor to throw. This currently affects only the OPFS VFSes. We may want to consider extending the ctor options object to optionally accept an SEE key and apply it when opening the db. (check-in: 5c505ee8 user: stephan tags: trunk)
00:42
Continuation of the fix at [8c0f69e0e4ae0a44]: If a viaCoroutine FROM clause term is participating in a RIGHT or FULL JOIN, we have to create an always-NULL pseudo-cursor for that term when processing the RIGHT join. dbsqlfuzz 6fd1ff3a64bef4a6c092e8d757548e95698b0df5. (check-in: e1040e51 user: drh tags: trunk)
2024-04-21
23:35
Fix an indentation problem in debugging routine sqlite3ShowSrcList(). No changes to production code. (check-in: 5560df27 user: drh tags: trunk)
2024-04-18
16:11
Correct handling of OUTER JOIN when on or the other operand is a subquery implemented using the VALUES-as-coroutine optimization. dbsqlfuzz bde3bf80aedf25afa56e2997a0545a314765d3f8. (check-in: 8c0f69e0 user: drh tags: trunk)
2024-04-15
20:43
The first assert() added in [0ebc65481f4a3e79] is not necessarily true in a corrupt database file. So add a term to make it true. (check-in: 6b21cccd user: drh tags: trunk)
2024-04-12
18:46
If a build fails in testrunner.tcl, do not attempt to run the jobs that depend on that build. Instead, report those jobs as having been skipped. (check-in: b40580be user: drh tags: trunk)
15:02
Fixes and new tests logic to ensure that the btree overflow page cache is only used when it is consistent. This resolves the malfunction observed in forum post 284955a3cd454a15. (check-in: 5dede50d user: drh tags: trunk)
2024-04-11
19:08

2024-04-09
19:23
Fix a "shift exponent is too large" usan error that could occur in the fts3 snippet() function when a query phrase contains more than 64 tokens. (check-in: 6d2c7ac4 user: dan tags: trunk)
15:09
Avoid some performance problems in the recover extension when recovering strategically corrupted databases. (check-in: e66a834b user: dan tags: trunk)
13:57
The read-only CHECK-constraint optimization of [34ddf02d3d21151b] inhibits the xfer optimization for tables with CHECK constraints. However, the xfer optimization is required for correct operation of VACUUM INTO on tables that contain generated columns. Fix this by ignoring CHECK constraints when qualifying the xfer optimization while running VACUUM. Problem reported by forum post 3ec177d68fe7fa2c. (check-in: a6e26e77 user: drh tags: trunk)
2024-04-08
17:55
Update tests in returning1.test to account for [c7896e88]. (check-in: c02956cd user: dan tags: trunk)
11:50
Enhance the WHERE-clause push-down optimization so that it is able to push down WHERE clause terms that contain uncorrelated subqueries. (check-in: 69ec714b user: drh tags: trunk)
11:45

2024-04-07
18:36
Omit all rowid-in-view restrictions from the fuzzinvariant.c test module as they are no longer necessary, as of the previous check-in. (check-in: 6431538f user: drh tags: trunk)
18:23
If SQLITE_ALLOW_ROWID_IN_VIEW is set to 2, then all rowids for views return a value of NULL. (check-in: 0a53dde2 user: drh tags: trunk)
10:27
Add comments to note the name abiguity between the MySQL push-down optimization and the WHERE-clause push-down optimization. (check-in: 3d5fb1ec user: drh tags: trunk)
2024-04-06
17:37
Improvements to the accurancy of the fuzzinvariants.c testing module when SQLITE_ALLOW_ROWID_IN_VIEW is defined and the test query involves rowids. (check-in: c6e873d4 user: drh tags: trunk)
2024-04-05
13:56
Check-in [a9657c87c53c1922] is wrong: the IndexedExpr.bMaybeNullRow flag is required for virtual columns if they are part of an outer join. Add a test case (derived from dbsqlfuzz b9e65e2f110df998f1306571fae7af6c01e4d92b) to prove it. (check-in: 4484ec6d user: drh tags: trunk)
11:23
When compiling with SQLITE_ALLOW_ROWID_IN_VIEW, if the RETURNING clause of an UPDATE of a view specifies a rowid, then return NULL for the value of that rowid. dbsqlfuzz 7863696e9e5ec10b29bcf5ab2681cd6c82a78a4a. (check-in: c7896e88 user: drh tags: trunk)
2024-04-04
22:53
Optimize sqlite3.oo1.DB.exec() for the rowMode='object' case to avoid converting the object property keys (column names) from native code to JS for each row. This speeds up large data sets considerably and addresses the report in forum post 3632183d2470617d. (check-in: 8b41ef86 user: stephan tags: trunk)
14:26
Add the "interstage-heuristic" that attempts to avoid wildly inefficient queries that use table scans instead of index lookups because the output row estimates are inaccurate. (check-in: 7bf49e2c user: drh tags: trunk)
13:36
Fix an ASAN problem in part of the test harness. No changes to SQLite itself. (check-in: 797cda7d user: drh tags: trunk)

2024-03-25
20:35
The RAISE() operator is not a constant expression and cannot participate in the VALUE-as-coroutine optimization. dbsqlfuzz 74cf7c9904360322a6c917e4934b127543d1cd51 (check-in: 6a06dc73 user: drh tags: trunk)

Fix a theoretical OOB memory access in sqlite3_stmt_scanstatus_v2(). (check-in: 87be9580 user: dan tags: trunk)
18:24
Revert the previous change. Instead, do a pre-check of the CREATE TABLE statement that is the second argument to sqlite3_declare_vtab() and if the first two keywords are not "CREATE" and "TABLE", then raise an SQLITE_MISUSE error. (check-in: 6a2ff835 user: drh tags: trunk)
17:43
Remove an ALWAYS() from a condition that can be true. (check-in: 715fcf03 user: drh tags: trunk)
14:44
Fix an inaccuracy in automatic indexes that was exposed by the fix at [80c4223098c1827f]. (check-in: fdc9406f user: drh tags: trunk)

22:18
Test case for the assert() problem fixed by [9ba3cff9d48fe8fc]. (check-in: 865f0de7 user: drh tags: trunk)
15:52
Add comments (only, no code) to the JS sqlite3_config() bindings reminding us why SQLITE_CONFIG_ROWID_IN_VIEW is specifically not included. JNI does not need this treatment because it explicitly supports only a very small subset of config options. (check-in: 4fea3962 user: stephan tags: trunk)
11:46
Enhancements to testrunner.tcl: (1) Add the "--config CONFIGS" option, to that only configuration named on the comma-separated list CONFIGS are run.

2024-03-20
16:56
Change EXPLAIN QUERY PLAN output to say "USE TEMP B-TREE FOR LAST TERM OF ORDER BY", or "LAST N TERMS OF ORDER BY", instead of "RIGHT PART OF ORDER BY". (check-in: 7e13a2c7 user: dan tags: trunk)
10:45
Fix the SQLITE_ALLOW_ROWID_IN_VIEW bug-compatibility option so that it works again. Add the SQLITE_CONFIG_ROWID_IN_VIEW sqlite3_config() value to optionally disable the bug-compatibility mode at start-time. Enable testing of SQLITE_ALLOW_ROWID_IN_VIEW. (check-in: b6802565 user: drh tags: trunk)
2024-03-19
19:42
Make sure the new u1.nRow value is copied when making a copy of a SrcItem object. This fixes a problem in [ac6f095e13e43d66] from yesterady. (check-in: 262f8f9d user: drh tags: trunk)
10:41
Adjustments to the test cases for the previous check-in to make them cross-platform Linux/Mac/Windows. Test changes only. No change to core code. (check-in: 0dddadbd user: drh tags: trunk)

Remove unnecessary blank lines from build commands in the default Makefile.in. (check-in: 76fb3a90 user: drh tags: trunk)
18:00
Add the "VALUES-as-coroutine" optimization. Large VALUES clauses on an INSERT, for example, prepare and run in about half the time and with half the memory. This check-in also includes enhancements to the internal sqlite3ExprIsConstant() routine to recognize pure SQL functions as constant if they have constant arguments. (check-in: a120c923 user: drh tags: trunk)
2024-03-15
17:57
New options for testrunner.tcl: --stop-on-error and --stop-on-coredump. (check-in: 82035b9c user: drh tags: trunk)
