There was a problem hiding this comment.
nit: might be worth a line in the createModule() docs on when return() gets called.
Closing a virtual table cursor invoked the iterator's return() even after next() had already reported done: true, deviating from for...of semantics where return() only runs on abrupt termination. An empty custom iterable with a throwing return() made an otherwise successful query fail. Only close the iterator when the scan stopped early, as with LIMIT, a break, or a cursor re-filter; a normally finished iterator already ran its cleanup.

sqlite: skip return() on exhausted virtual table iterators Closing a virtual table cursor invoked the iterator's return() even after next() had already reported done: true, deviating from for...of semantics where return() only runs on abrupt termination. An empty custom iterable with a throwing return() made an otherwise successful query fail. Only close the iterator when the scan stopped early, as with LIMIT, a break, or a cursor re-filter; a normally finished iterator already ran its cleanup. Likewise, skip return() after an iterator protocol error, where next() is missing or returns a non-object, as for...of does not close the iterator in that case.

Fixes: #66518
Once a virtual table iterator's
next()reportsdone: true, the iterator is finished, soreturn()must not be called. This matchesfor...of, which callsreturn()only on abrupt termination. Before this change, an empty custom iterable with a throwingreturn()made an otherwise successful query fail.CloseIterator()now skips cursors whose iteration has completed. That covers bothxCloseand cursor re-filtering. Early termination (LIMIT,break, re-filter mid-scan) still callsreturn().Assisted-by: claude:opus-5.5
