Module type Ketrew_long_running.LONG_RUNNING

module type LONG_RUNNING = sig .. end

The module type LONG_RUNNING defines the interface for plugins.

type run_parameters

Hidden type kept serialized by the engine.

val name : string

The (unique) name of the plugin.

val serialize : run_parameters -> string

Serialize the run parameters for storage by the engine.

val deserialize_exn : string -> run_parameters

Deserialize the run parameters from a string; the engine guaranties that deserialize_exn will be called on the result of Ketrew_long_running.LONG_RUNNING.serialize; and assumes that no exception will be thrown in that case.

val start : run_parameters ->
       (run_parameters, Ketrew_long_running.error)
       Ketrew_unix_io.Deferred_result.t

Start the long-running computation, the returned run_parameters will be stored and used for the first call to Ketrew_long_running.LONG_RUNNING.update.

val update : run_parameters ->
       ([ `Failed of run_parameters * string
        | `Still_running of run_parameters
        | `Succeeded of run_parameters ],
        Ketrew_long_running.error)
       Ketrew_unix_io.Deferred_result.t

Check and update the status of the long-running job. Again, is `Still_running rp is returned, the next call to Ketrew_long_running.LONG_RUNNING.update (or Ketrew_long_running.LONG_RUNNING.kill) will receive those parameters.

val kill : run_parameters ->
       ([ `Killed of run_parameters ],
        Ketrew_long_running.error)
       Ketrew_unix_io.Deferred_result.t

Kill the long-running computation.

val log : run_parameters ->
       (string * Ketrew_pervasives.Log.t) list

Get a list of things to display.

val additional_queries : run_parameters ->
       (string * Ketrew_pervasives.Log.t) list

List of potential (query, description) pairs that can be passed to Ketrew_long_running.LONG_RUNNING.query.

val query : run_parameters ->
       string -> (string, Ketrew_pervasives.Log.t) Ketrew_unix_io.Deferred_result.t

Perform a query.
