Functions ¶

func AddStatusFuncs ¶

func AddStatusFuncs(fmap template.FuncMap)

AddStatusFuncs merges the provided functions into the set of functions used to render /debug/status. Call this before AddStatusPart if your template requires custom functions.

func AddStatusPart ¶

func AddStatusPart(banner, frag string, f func() interface{})

AddStatusPart adds a new section to status. frag is used as a subtemplate of the template used to render /debug/status, and will be executed using the value of invoking f at the time of the /debug/status request. frag is parsed and executed with the html/template package. Functions registered with AddStatusFuncs may be used in the template.

func AddStatusSection ¶

func AddStatusSection(banner string, f func() string)

AddStatusSection registers a function that generates extra information for /debug/status. If banner is not empty, it will be used as a header before the information. If more complex output than a simple string is required use AddStatusPart instead.

func CheckServiceMap ¶

func CheckServiceMap(protocol, name string) bool

CheckServiceMap returns if we should register a RPC service (and also logs how to enable / disable it)

func Close ¶

func Close()

Close runs any registered exit hooks in parallel.

func GRPCCheckServiceMap ¶

func GRPCCheckServiceMap(name string) bool

GRPCCheckServiceMap returns if we should register a gRPC service (and also logs how to enable / disable it)

func HandlePanic ¶

func HandlePanic(component string, err *error)

HandlePanic should be called using 'defer' in the RPC code that executes the command.

func Init ¶

func Init()

func InitServiceMap ¶

func InitServiceMap(protocol, name string)

InitServiceMap will set the default value for a protocol/name to be served.

func OnClose ¶

func OnClose(f func())

OnClose registers f to be run at the end of the app lifecycle. This happens after the lameduck period just before the program exits. All hooks are run in parallel.

func OnRun ¶

func OnRun(f func())

OnRun registers f to be run right at the beginning of Run. All hooks are run in parallel.

func OnTerm ¶

func OnTerm(f func())

OnTerm registers a function to be run when the process receives a SIGTERM. This allows the program to change its behavior during the lameduck period.

All hooks are run in parallel, and there is no guarantee that the process will wait for them to finish before dying when the lameduck period expires.

func OnTermSync ¶

func OnTermSync(f func())

OnTermSync registers a function to be run when the process receives SIGTERM. This allows the program to change its behavior during the lameduck period.

All hooks are run in parallel, and the process will do its best to wait (up to -onterm_timeout) for all of them to finish before dying.

func Register ¶

func Register(name string, rcvr interface{})

Register registers a bsonrpc service according to serviceMap

func RegisterDefaultFlags ¶

func RegisterDefaultFlags()

RegisterDefaultFlags registers the default flags for listening to a given port for standard connections. If calling this, then call RunDefault()

func RegisterDefaultSocketFileFlags ¶

func RegisterDefaultSocketFileFlags()

RegisterDefaultSocketFileFlags registers the default flags for listening to a socket. It also registers an OnRun callback to enable the listening socket. This needs to be called before flags are parsed.
