func CreateTlsConfig ¶

func CreateTlsConfig(minVersion uint16, rootCAs *string, host string, tlsHost string, skipCertVerification bool) (*tls.Config, error)

func CreateTlsConfigFromRootCAString ¶

func CreateTlsConfigFromRootCAString(minVersion uint16, rootCAs string, host string, tlsHost string, skipCertVerification bool) (*tls.Config, error)

CreateTlsConfigFromRootCAString adapts CreateTlsConfig for callers that pass rootCAs as a string rather than *string (e.g. mongo ClientConfig). Empty string is treated as no custom CA.

func HeartbeatRoutine ¶

func HeartbeatRoutine(
	ctx context.Context,
	message func() string,
) func()

func Interval ¶

func Interval(
	ctx context.Context,
	freq time.Duration,
	fn func(),
) func()

func QuoteIdentifier ¶

func QuoteIdentifier(name string) string

QuoteIdentifier quotes an "identifier" (e.g. a table or a column name) to be used as part of an SQL statement. For example:

tblname := "my_table"
data := "my_data"
quoted := common.QuoteIdentifier(tblname)
err := db.Exec(fmt.Sprintf("INSERT INTO %s VALUES ($1)", quoted), data)

Any double quotes in name will be escaped. The quoted identifier will be case-sensitive when used in a query. If the input string contains a zero byte, the result will be truncated immediately before it.
