Functions

func CleanOpError

func CleanOpError(err error) error

CleanOpError checks whether a *net.OpError is included in the error and if so removes the included address information. This can happen in two ways: If the passed error is indeed an OpError the address info is just patched out. If the OpError is buried deeper inside the wrapped error stack, a new error with patched message is created sacrificing the wrapping and possible included stacktrace.

As of the loss of information this is only intended to clean up logging and not be used in error returns.

func Retry

func Retry(fn func() error) error

Retry contains a standard set of configuration parameters for an exponential backoff to be used throughout the bot

func RetryTransaction

func RetryTransaction(db *gorm.DB, fn func(tx *gorm.DB) error) error

RetryTransaction takes a database object and a function acting on the database. The function will be run in a transaction on the database and will be retried as if executed using Retry
