Fix for errors: Plugin sha256_password reported #439
Conversation
In the absence of --skip-grant-table, the database creates an acl_user object through the function decoy_user() when a non-existent user is logged into the database. When this object is created, its plugin property is randomly selected from cached_plugins_enum. This makes it possible to select the PLUGIN_SHA256_PASSWORD plug-in. But at the entrance to sha256_password_authenticate(), a Warning message is generated indicating that PLUGIN_SHA256_PASSWORD is deprecated: 2023-01-10T01:07:23.035479Z 13 [Warning] [MY-013360] [Server] Plugin sha256_password reported: ''sha256_password' is deprecated and will be removed in a future release. Please use caching_sha2_password instead' When invalid database access occurs due to objective reasons, a large number of Warning logs are generated in the database error log. As a result, alarms and log files are too large. Therefore, the decoy_user() function removes PLUGIN_SHA256_PASSWORD to fix the problem without affecting other functions.
