| Description: | ||||
The following script causes a crash:
CREATE VIRTUAL TABLE f1 USING fts3;
BEGIN;
INSERT INTO f1 VALUES('a b c');
DROP TABLE f1;
SAVEPOINT one;
This is not an FTS specific problem. It can occur using any virtual table implementation that sets sqlite3_module.iVersion>=2 (i.e. one that requires callbacks for SAVEPOINT, ROLLBACK TO and RELEASE commands). To reproduce this, the user must open a transaction, write to the virtual table and then DROP it. Thereafter, any SAVEPOINT, ROLLBACK TO or RELEASE command within the transaction that is not a no-op will cause a crash. dan added on 2011-10-29 11:46:05: dan added on 2011-10-29 11:54:59: | ||||
