Re: Assertion `! is_set()' failed in Diagnostics_area::set_ok_status(THD*, ha_rows, ulonglong, const char*) on CREATE .. SELECT with ER_SUBQUERY_NO_1_ROW
Tried 5.3 with:
revno: 3424
revision-id: psergey@askmonty.org-20120216161557-iwh5ki59q8aer7n1
compiled with ./BUILD/compile-pentium-debug-max-no-ndb on x86_64. Still was unable to repeat.

Elena could you help with repeating this bug?
Re: Assertion `! is_set()' failed in Diagnostics_area::set_ok_status(THD*, ha_rows, ulonglong, const char*) on CREATE .. SELECT with ER_SUBQUERY_NO_1_ROW
I've rebuilt the latest 5.3, the bug is still reproducible for me on revision-id: psergey@askmonty.org-20120222124829-1eluifx00def36e6 (revno: 3437), openSUSE 11.3, both i686 and x86_64, built with the same BUILD/compile-pentium-debug-max-no-ndb. I've set up a test tree on the remote test machine so we could share the environment, details on the IRC.
Re: Assertion `! is_set()' failed in Diagnostics_area::set_ok_status(THD*, ha_rows, ulonglong, const char*) on CREATE .. SELECT with ER_SUBQUERY_NO_1_ROW
Ok, here is why I was unable to repeat: the bug only show up when binary logging is disabled.
Re: Assertion `! is_set()' failed in Diagnostics_area::set_ok_status(THD*, ha_rows, ulonglong, const char*) on CREATE .. SELECT with ER_SUBQUERY_NO_1_ROW
The problem does not show up when the error occurs inside
select_insert::send_data().
It only shows up when
- The "subquery returns > 1 row" error occurs when checking
exec_const_cond (that is, at execution phase we find out that
there won't be any matching rows). - After that, select_insert::send_eof() fails to deal with error state.
Attempts to repeat this situation with a failure in other clause than
exec_const_cond were not successfull: I can either
- get an error in select_insert::send_data(), which is handled
- get an error elsewhere, which causes a general error condition and a
call to select_create::abort() (and not ::send_data).

Fix released with 5.3.5-ga.
