Description
Set to Minor because the scenario is unlikely to be important from the user perspective.
When the "remote" and "local" tables are on the same server, INSERT INTO <spider> SELECT FROM <underlying InnoDB table> locks up until innodb_lock_wait_timeout is exceeded. Same for CREATE .. SELECT.
# Spider init should be here instead |
install soname 'ha_spider'; |
|
|
--source include/have_innodb.inc
|
|
|
SET spider_same_server_link= on; |
--eval create server s foreign data wrapper mysql options (host "127.0.0.1", database "test", user "root", port $MASTER_MYPORT);
|
|
|
CREATE TABLE t (a INT) ENGINE=InnoDB; |
INSERT INTO t VALUES (1); |
SET spider_same_server_link= on; |
SET GLOBAL innodb_lock_wait_timeout= 1; |
CREATE TABLE t_spider (a INT) ENGINE=SPIDER COMMENT = "wrapper 'mysql', srv 's', table 't'"; |
INSERT INTO t_spider SELECT * FROM t; |
|
|
# Cleanup
|
|
|
DROP TABLE t_spider, t; |
DROP SERVER s; |
SET GLOBAL innodb_lock_wait_timeout= @@innodb_lock_wait_timeout; |
|
|
# Spider de-init should be here

Reproducible on 10.4+, didn't try 10.3, I don't think there is any point in fixing it there even if it's fixable.
