Description
If server is started with --plugin-load-add=ha_spider, it throws an error on startup.
--let restart_parameters= --plugin-load-add=ha_spider
|
--source include/restart_mysqld.inc
|
|
SELECT COUNT(*) FROM information_schema.SPIDER_ALLOC_MEM; |
10.7 dd9da61d |
[ERROR] SPIDER plugin initialization failed at 'drop procedure if exists mysql.spider_fix_one_table' by 'Unknown storage engine 'Aria''
|
2022-10-27 22:19:57 0 [ERROR] Plugin 'SPIDER' init function returned error.
|
2022-10-27 22:19:57 0 [ERROR] Plugin 'SPIDER' registration as a STORAGE ENGINE failed.
|
And if instead the plugin is installed into mysql.plugin, the failure upon server restart is different:
INSTALL SONAME 'ha_spider'; |
--source include/restart_mysqld.inc
|
SELECT COUNT(*) FROM information_schema.SPIDER_ALLOC_MEM; |
[ERROR] SPIDER plugin initialization failed at 'drop procedure mysql.spider_fix_one_table' by 'The MariaDB server is running with the --skip-grant-tables option so it cannot execute this statement'
|
2022-10-28 0:54:26 0 [ERROR] Plugin 'SPIDER' init function returned error.
|
2022-10-28 0:54:26 0 [ERROR] Plugin 'SPIDER' registration as a STORAGE ENGINE failed.
|
It happens regardless of the build type (debug, release, all the same).
On a debug build, additionally a query from a spider system table causes a mutex failure.
