From ec8e9a96bd0d0148df5008b0665da0725e5b3f92 Mon Sep 17 00:00:00 2001 From: Ingela Anderton Andin Date: Tue, 4 Mar 2014 12:21:14 +0100 Subject: inets: Reverted commmit f97cd6965ac35d1cbe510de23592956857d144c8 The reverted commit took a too optimistic approch to pipeling. When added we thought it would be an improvment, but it proved to be a misconception. --- lib/inets/src/http_client/httpc_handler.erl | 44 +++++++++++++++++++------- lib/inets/src/http_client/httpc_internal.hrl | 6 ++-- lib/inets/src/http_client/httpc_manager.erl | 46 +++++++++------------------- lib/inets/test/httpc_SUITE.erl | 8 ++++- 4 files changed, 58 insertions(+), 46 deletions(-) diff --git a/lib/inets/src/http_client/httpc_handler.erl b/lib/inets/src/http_client/httpc_handler.erl index a89a457a51..0957eb3261 100644 --- a/lib/inets/src/http_client/httpc_handler.erl +++ b/lib/inets/src/http_client/httpc_handler.erl @@ -1154,7 +1154,7 @@ handle_http_body(Body, #state{headers = Headers, handle_response(#state{status = new} = State) -> ?hcrd("handle response - status = new", []), - handle_response(check_persistent(State)); + handle_response(try_to_enable_pipeline_or_keep_alive(State)); handle_response(#state{request = Request, status = Status, @@ -1429,22 +1429,39 @@ is_keep_alive_enabled_server(_,_) -> is_keep_alive_connection(Headers, #session{client_close = ClientClose}) -> (not ((ClientClose) orelse httpc_response:is_server_closing(Headers))). -check_persistent( - #state{session = #session{type = Type} = Session, +try_to_enable_pipeline_or_keep_alive( + #state{session = Session, + request = #request{method = Method}, status_line = {Version, _, _}, headers = Headers, - profile_name = ProfileName} = State) -> + profile_name = ProfileName} = State) -> + ?hcrd("try to enable pipeline or keep-alive", + [{version, Version}, + {headers, Headers}, + {session, Session}]), case is_keep_alive_enabled_server(Version, Headers) andalso - is_keep_alive_connection(Headers, Session) of + is_keep_alive_connection(Headers, Session) of true -> - mark_persistent(ProfileName, Session), - State#state{status = Type}; + case (is_pipeline_enabled_client(Session) andalso + httpc_request:is_idempotent(Method)) of + true -> + insert_session(Session, ProfileName), + State#state{status = pipeline}; + false -> + insert_session(Session, ProfileName), + %% Make sure type is keep_alive in session + %% as it in this case might be pipeline + NewSession = Session#session{type = keep_alive}, + State#state{status = keep_alive, + session = NewSession} + end; false -> State#state{status = close} end. answer_request(#request{id = RequestId, from = From} = Request, Msg, - #state{timers = Timers, + #state{session = Session, + timers = Timers, profile_name = ProfileName} = State) -> ?hcrt("answer request", [{request, Request}, {msg, Msg}]), httpc_response:send(From, Msg), @@ -1454,14 +1471,19 @@ answer_request(#request{id = RequestId, from = From} = Request, Msg, Timer = {RequestId, TimerRef}, cancel_timer(TimerRef, {timeout, Request#request.id}), httpc_manager:request_done(RequestId, ProfileName), + NewSession = maybe_make_session_available(ProfileName, Session), Timers2 = Timers#timers{request_timers = lists:delete(Timer, RequestTimers)}, State#state{request = Request#request{from = answer_sent}, + session = NewSession, timers = Timers2}. -mark_persistent(ProfileName, Session) -> - update_session(ProfileName, Session, #session.persistent, true), - Session#session{persistent = true}. +maybe_make_session_available(ProfileName, + #session{available = false} = Session) -> + update_session(ProfileName, Session, #session.available, true), + Session#session{available = true}; +maybe_make_session_available(_ProfileName, Session) -> + Session. cancel_timers(#timers{request_timers = ReqTmrs, queue_timer = QTmr}) -> cancel_timer(QTmr, timeout_queue), diff --git a/lib/inets/src/http_client/httpc_internal.hrl b/lib/inets/src/http_client/httpc_internal.hrl index d5b3dd2a2a..add5d11dfa 100644 --- a/lib/inets/src/http_client/httpc_internal.hrl +++ b/lib/inets/src/http_client/httpc_internal.hrl @@ -1,7 +1,7 @@ %% %% %CopyrightBegin% %% -%% Copyright Ericsson AB 2005-2013.
