Fix for the assertion faults reported by forum post e45108732c and forum post 44270909bb. (check-in: cf6454ce user: drh tags: trunk)
15:01
Add the SQLITE_VTAB_USES_ALL_SCHEMAS option to sqlite3_vtab_config(). Update the sqlite_dbpage, sqlite_dbdata, and sqlite_dbptr virtual tables to make use of that interface. This was formerly handled by the internal sqlite3VtabUsesAllSchemas() routine that was called directly from sqlite_dbpage. But since sqlite_dbdata and sqlite_dbptr are an extension, an external interface to that functionality had to be provided. dbsqlfuzz 1a29c245175a63393b6a78c5b8cab5199939d6a8 (check-in: bcd51abe user: drh tags: trunk)

Enhance PRAGMA integrity_check so that it can detect that a NOT NULL column contains a NaN value and report that as an error. dbsqlfuzz f144b642fe6f1a1c196f258ac6e60118a0cb59b2. (check-in: 7638d975 user: drh tags: trunk)
00:05
Modify the OP_IsType opcode so that it does not need to distinguish between NaN and other floating point values. Later: This branch causes an unnecessary slowdown of PRAGMA integrity_check. Check-in [7638d9755dc90fd3] does a better job of detecting when a NaN value occurs in a NOT NULL column. (Closed-Leaf check-in: 242cb36c user: drh tags: istype-opcode-refactor)

11:18
Fix multiple problems with RETURNING on a DML statement against a view, all inspired by forum post dc3b92cfa0. (1) Do not allow a RETURNING clause to trick the code generator into thinking that the view being updated has an INSTEAD OF trigger. (2) Generate all result columns for a view in a DML statement. (3) The automatic covering index for a view should cover all result columns of the view. (check-in: c8bedef0 user: drh tags: trunk)

Remove a meaningless JS test. Add a timer to the OPFS async-side worker loader in an attempt to catch a browser-specific quirk in which the worker loading silently fails, per discussion in/around [forum post a708c98dcb3ef|forum:a708c98dcb3ef]. (check-in: 4fc1904b user: stephan tags: trunk)
13:24
Do not allow constant factoring during PRAGMA integrity_check, since the constants might be stored in registers that are later reused for other purposes. dbsqlfuzz dc9ab26037cf5ef797d28cd1ae0855ade584216d. Problem discovered by a new assert() statement added in [6f8b97f31a4c8552]. (check-in: 0bba27b7 user: drh tags: trunk)
2023-03-26
16:36
Improvements to register allocation, especially in the ANALYZE command. New assert() statements added to help verify that memory allocation is correct, and to help fuzzer find lingering errors. (check-in: 6f8b97f3 user: drh tags: trunk)
11:54
Disable factoring of constant values during ANALYZE. This is a temporary fix for forum post 07de5f6216. The register allocation logic in ANALYZE needs to be completely refactored, but that will take longer. This check-in will serve to resolve the issue until a better fix can be devised. (check-in: c3967d12 user: drh tags: trunk)

When the left table of a RIGHT JOIN is used inside an aggregate function and the left table employs an index on expressions, then make sure the expressions evaluate to NULL for the cases where the left table should be NULL. Proposed fix for forum post 9b491e1deb. More testing an analysis needed - there is a FIXME in this check-in. (check-in: 3572b40a user: drh tags: rightjoin-agg-idxexpr)

In the byte-code generator, when the result of an expression needs to be in a particular register, always use the sqlite3ExprCode() routine because it has the smarts to know whether to use OP_Copy or OP_SCopy. Do not try to OP_SCopy inline because an OP_Copy might be required. Fix for the problem identified by forum post 5522082cfc. (check-in: c104e5c6 user: drh tags: trunk)

The fix at [2bf5413dc2c19d5f] was incomplete in that it failed to clear the reusable register cache that might contain registers in the STAT4 buffer region. This additional change corrects the problem. Forum post 83cb4a95a0. Test case in TH3. (check-in: 5d554e4d user: drh tags: trunk)

The attempt to bring STAT4 up to 100% MC/DC at [55a26c67ed4a3a93] and at [168fa2fb22b8c1ad] are incorrect. Back them out and replace them with a simple NEVER() macro. Error reported by forum post dc4854437b. (check-in: 5992370a user: drh tags: trunk)

20:21
Add the SQLITE_ENABLE_NAN_INF compile-time option which makes the following behavior changes: (1) sqlite3_value_double(NULL) returns NaN, (2) SQLite preserves NaN values rather than converting them to NULL. (3) CAST statements understand "NaN" and "Inf" and make the right conversions. (4) Non-standard JSON is never generated by SQLite JSON routines, but those routines will accept floating point literals "NaN", "Inf", and "-Inf". (check-in: 96ec8306 user: drh tags: nan-inf)

The double-to-text conversion renders infinity as 9e999, so that JSON output is compliant and so that values can be round-tripped. (check-in: b52081d0 user: drh tags: trunk)

In the CLI, the magic parameter :inf and :nan bind floating point values Infinity and NaN, respectively, as an aid to testing SQLite's handling of those quantities. (check-in: c70a61d8 user: drh tags: trunk)
