Module Tcp_file.Server

module Server: sig .. end

module File: sig .. end
val serve : auth:(Import.Socket.Address.Inet.t -> bool) ->
port:int -> Tcp.Server.inet Import.Deferred.t
serve ~port () must be called before clients will be able to connect. Sets up a bound tcp socket on port that will be used to serve files to clients. The unit Deferred will be filled when the server is ready to receive clients.

The auth function will be called once for every client connection. If it returns false the client will be disconnected immediately. Further details of auth can be found in the documentation for Rpc.serve.

val open_file : ?append:bool ->
?dos_format:bool -> string -> File.t Import.Deferred.t
open_file filename open a file for writing. The filename given should be a real path on the server, and will create a real file there
val serve_existing_static_file : string -> unit Import.Deferred.t
serve_existing_static_file filename adds filename to the list of files that can be accessed via the Client module. As indicated in the name, this file must already exist and must not grow or change. When a client requests the file it will be served from beginning to end.
val stop_serving : File.t -> unit
stop_serving t stops serving the file t to clients. Calling this function will not close the file if it is open. (A possible use of this function is if you want to delete the file on the sending side.)
val close : ?stop_serving:bool -> File.t -> unit Import.Deferred.t
close t closes the file t for writing. If stop_serving is false (default is true) the file will be left on disk and will still be served to clients on a create request.
val write_message : File.t -> string -> unit
write_message t msg write msg to t. msg is assumed to contain no newlines except possibly at the end. A newline will be added to the end in the file if it is not present. The message may be transmitted to clients with or without a newline. The string passed to write_message is copied and so may be freely modified once write_message returns.
val schedule_message : File.t -> Core.Std.Bigstring.t -> unit
schedule_message t msg is write, but the message is taken from the provided bigstring. Once a bigstring has been given to this function it is a mistake to ever modify the bigstring in the future. This is because it will take an unknown amount of time to deliver the message to all connected clients
val write_sexp : File.t -> Core.Std.Sexp.t -> unit
write_sexp t sexp writes a Sexp.t as a single message
val flushed : File.t -> unit Import.Deferred.t
flushed t becomes determined only once all messages written to t have been written to disk.
val with_file : ?append:bool ->
string ->
f:(File.t -> 'a Import.Deferred.t) -> 'a Import.Deferred.t
with_file filename ~f opens filename and runs f, passing the resultant t. When the deferred returned by f is determined, t will be closed.
val writer_monitor : File.t ->
(Import.Monitor.t, [ `This_is_a_static_file ]) Core.Std.Result.t
monitor t returns a monitor which will listen to errors arising from the internal writer used by t.
val debug_snapshot : unit -> Core.Std.Sexp.t
debug_snapshot () returns an s-expression containing details of the current state of the Tcp_file server.
