I have gone through the patches and tested the patch series.
I successfully reproduced the bug before applying the patch and found
that the cross-session SELECT via schema-qualified temp table did not
raise an error; instead, it returned an empty result, indicating
inconsistent behaviour. After applying the patch, regression tests
passed successfully and new regression tests behave as expected.
Temporary tables from other sessions are now no longer visible and all
the attempts to access them result in error. Also I verified:-
Schema-qualified SELECT, INSERT / UPDATE / DELETE, JOIN queries,
Subqueries and EXPLAIN worked as expected. Same-session access also
works as expected. Overall the patch LGTM.
