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. (Leaf 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

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)

2024-04-05
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)

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)

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)

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.

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

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

Fuzzcheck is run automatically by testrunner.tcl, so there is no need to include fuzzcheck as a separate dependency for the releasetest target in the MSVC makefile. (check-in: 76629b2b user: drh tags: trunk)
2024-03-08
21:37
The NOT NULL strength reduction optimization from [de9c86c9e4cdb34f] should be applied to the WHERE clause only. Otherwise, the operand of the IS NULL or IS NOT NULL operator might be a reference to a bare column of an aggregate table, and we can't tell if it is NULL or not based only on its NOT NULL attribute. Forum post 440f2a2f17. (check-in: 51704fea user: drh tags: trunk)
19:03

09:23
When warning about multiple invocations of JS's sqlite3ApiBootstrap(), use the warning logger installed by the first invocation, rather than console.warn. (check-in: d162af2d user: stephan tags: trunk)
06:54
After wasm bootstrapping has read the optional global-scope config objects, delete those objects because any further changes would not have any useful effect.

Enhancements to PRAGMA optimize and ANALYZE. Add the 0x10000 flag to PRAGMA optimize. ANALYZE now records zero-size partial indexes in the sqlite_stat1 table. PRAGMA optimize looks for both growth and shrinkage in table sizes, and uses tighter bounds (10x rather than 25x) to trigger a re-analyze. PRAGMA optimize automatically uses are reasonable analysis_limit to prevent excessive runtimes. (check-in: 63ef234e user: drh tags: trunk)
