# ==== Purpose ====
#
# This script tests error handling regarding setting session and/or global
# variables while applying events in the replication stream.
#
# ==== Requirements ====
#
# R1. Variables `auto_increment_increment`, `auto_increment_offset`,
# `collation_database`, `explicit_defaults_for_timestamp`,
# `default_collation_for_utf8mb4` and `rbr_exec_mode` are allowed to be set
# without privileges.
# R2. Variables `gtid_next`, `original_commit_timestamp`,
# `original_server_version`, `immediate_server_version` and
# `pseudo_replica_mode` are allowed to be set when having `SUPER`,
# `SYSTEM_VARIABLES_ADMIN`, `SESSION_VARIABLES_ADMIN` or
# `REPLICATION_APPLIER` privileges.
# R3. Variables `pseudo_thread_id` and `sql_require_primary_key` are allowed to
# be set when having `SUPER`, `SYSTEM_VARIABLES_ADMIN`,
# `SESSION_VARIABLES_ADMIN` privileges.
# R4. Variable `default_table_encryption` is allowed to be set when having
# `SUPER` or both `SYSTEM_VARIABLES_ADMIN` and `TABLE_ENCRYPTION_ADMIN`
# privileges.
#
# ==== Implementation ====
#
# TC1. Verify that replication only succeeds with `SYSTEM_VARIABLES_ADMIN` due
# to the set of `pseudo_thread_id`
# -----------------------------------------------------------------------------
# 1) Create a table on the master and insert a record.
# 2) Grant `REPLICATION_APPLIER`, `CREATE`, `DROP` and `INSERT` to the
# `PRIVILEGE_CHECKS_USER` user.
# 3) Start slave and wait for applier to error out.
# 4) Stop the slave.
# 5) Grant `SYSTEM_VARIABLES_ADMIN` to the `PRIVILEGE_CHECKS_USER` user.
# 6) Start the slave and sync it with master.
# 7) Ensure that database contents are the same in master and slave.
#
# TC2. Verify that replication only succeeds with `SUPER` due
# to the set of `pseudo_thread_id`
# -----------------------------------------------------------------------------
# 1) Create a table on the master and insert a record.
# 2) Grant `REPLICATION_APPLIER`, `CREATE`, `DROP` and `INSERT` to the
# `PRIVILEGE_CHECKS_USER` user.
# 3) Start slave and wait for applier to error out.
# 4) Stop the slave.
# 5) Grant `SUPER` to the `PRIVILEGE_CHECKS_USER` user.
# 6) Start the slave and sync it with master.
# 7) Ensure that database contents are the same in master and slave.
#
# TC3. Verify that replication only succeeds with `SESSION_VARIABLES_ADMIN` due
# to the set of `pseudo_thread_id`
# -----------------------------------------------------------------------------
# 1) Create a table on the master and insert a record.
# 2) Grant `REPLICATION_APPLIER`, `CREATE`, `DROP` and `INSERT` to the
# `PRIVILEGE_CHECKS_USER` user.
# 3) Start slave and wait for applier to error out.
# 4) Stop the slave.
# 5) Grant `SESSION_VARIABLES_ADMIN` to the `PRIVILEGE_CHECKS_USER` user.
# 6) Start the slave and sync it with master.
# 7) Ensure that database contents are the same in master and slave.
#
# TC4. Verify that setting `default_table_encryption` only succeeds on the slave
# when having `SUPER` or `SYSTEM_VARIABLES_ADMIN` and
# `TABLE_ENCRYPTION_ADMIN`
# ------------------------------------------------------------------------------
# 1) Change value for `default_table_encryption` on master and create a new
# database.
# 2) Ensure that `PRIVILEGE_CHECKS_USER` doesn't have the necessary privileges
# to set `default_table_encryption`.
# 3) Start slave and wait for applier to error out.
# 4) Grant `SYSTEM_VARIABLES_ADMIN` and `TABLE_ENCRYPTION_ADMIN` to
# `PRIVILEGE_CHECKS_USER` user.
# 5) Start the slave and sync it with master.
# 6) Ensure that we can use the database on the slave.
