fix(amqp091): close BrokerDetails.state and Test_Retry races#104
Merged
Conversation
…nect, and Test_connect_connecting_* Three pre-existing races surfaced under -race in this package: - BrokerDetails.state was a uint16 written under bd.Mutex by connect() and connectionWatcher() but read without the lock from WaitForConnect, queueSubscribe, Publish, and connect()'s own CONNECTING fast-path check. Converted to atomic.Uint32 so all reads/writes synchronize, and dropped the now-redundant Lock()/Unlock() around state-only writes in connectionWatcher. - getBrokerDetails() unconditionally reassigned bd.tlsConfig on every call, racing with concurrent reads of bd.tlsConfig in connect(). The assignment was redundant: BrokerDetails is constructed with tlsConfig: prov.tlsConfig and prov.tlsConfig is never reassigned after NewAMQP091Provider, so removing the write fixes the race without changing behavior. - Test_Retry built an amqp091Message, started a goroutine that sent it on a channel, and only then mutated mm.Headers from the test goroutine. Moved the Headers assignment ahead of the goroutine so the value is fully populated before it is sent. Test_Retry, Test_WaitForConnect, Test_connect_connecting_connected, Test_connect_connecting_closed, and Test_connect_connecting_disconnected now pass under \`go test -race\`.

BrokerDetails.statetoatomic.Uint32(dropping the now-redundant locking inconnectionWatcher), remove the redundantbd.tlsConfigrewrite ingetBrokerDetails, and move theTest_RetryHeadersassignment ahead of the goroutine that sends the message.
