sqlite-autoconf-3450100 (3.45.1)

[Bruce Dubbs]

New point version.

[Xi Ruoyao]

• Restore the JSON BLOB input bug, and promise to support the anomaly in subsequent releases, for backward compatibility.
• Fix the PRAGMA integrity_check command so that it works on read-only databases that contain FTS3 and FTS5 tables. This resolves an issue introduced in version 3.44.0 but was undiscovered until after the 3.45.0 release.
• Fix issues associated with processing corrupt JSONB inputs:
• Prevent exponential runtime when converting a corrupt JSONB into text.
• Fix a possible read of one byte past the end of the JSONB blob when converting a corrupt JSONB into text.
• Enhanced testing using jfuzz to prevent any future JSONB problems such as the above.
• Fix a long-standing bug in which a read of a few bytes past the end of a memory-mapped segment might occur when accessing a craftily corrupted database using memory-mapped database.
• Fix a long-standing bug in which a NULL pointer dereference might occur in the bytecode engine due to incorrect bytecode being generated for a class of SQL statements that are deliberately designed to stress the query planner but which are otherwise pointless.
