track()

void Rpl_opt_tracker::track ( const Tracker_service_guard &  service_guard, bool  enabled, const std::string &  fname, unsigned long long &  usage_counter  )

staticprivate

Tracks a feature, including the usage data.

It only updates usage data if the feature is enabled. Internal method to be used after the mysql_option_tracker_option service is acquired.

Parameters

service_guard	acquired service guard
enabled	true: tracks as enabled false: tracks as disabled
fname	feature name
usage_counter	feature usage counter

track_binary_log()

void Rpl_opt_tracker::track_binary_log ( const Tracker_service_guard &  service_guard, bool  enabled  ) const

private

Tracks the Binary Log feature, including the usage data.

It only updates usage data if the feature is enabled. Internal method to be used after the mysql_option_tracker_option service is acquired.

Parameters

service_guard	acquired service guard
enabled	true: tracks as enabled false: tracks as disabled

track_replication_replica() [1/2]

void Rpl_opt_tracker::track_replication_replica

(

bool

enabled

)

const

Tracks the Replication Replica feature, including the usage data.

It only updates usage data if the feature is enabled.

Parameters

enabled

true: tracks as enabled false: tracks as disabled

track_replication_replica() [2/2]

void Rpl_opt_tracker::track_replication_replica ( const Tracker_service_guard &  service_guard, bool  enabled  ) const

private

Tracks the Replication Replica feature, including the usage data.

It only updates usage data if the feature is enabled.

Parameters

service_guard	acquired service guard
enabled	true: tracks as enabled false: tracks as disabled

worker()

void Rpl_opt_tracker::worker

(

)

The thread worker that periodically tracks the replication features.
