From b5a4b788c2b6c6c62d930519dd36ed89832207db Mon Sep 17 00:00:00 2001 From: Nelson Vides Date: Mon, 30 May 2022 14:45:32 +0200 Subject: [PATCH 01/56] Prepare a new C2S prototype This time the listener is supervised using ranch, which already does everything our mongoose_tcp_listener does, plus a few more details like using pools of supervisors instead of all the many c2s processes having to be started and handled their termination through a single supervisor that can become a bottleneck. Using ranch of course also means one piece of our architecture that we don't need to maintain, but that the industry already maintains and optimise for us. Open source! The new mongoose_c2s_listener module implements our mongoose_listener behaviour, that gives mongoose_listener_sup a child_spec with the ranch definitions. --- rebar.config | 1 + rebar.lock | 6 ++-- src/mongoose_c2s.erl | 55 +++++++++++++++++++++++++++++++++++ src/mongoose_c2s_listener.erl | 48 ++++++++++++++++++++++++++++++ 4 files changed, 107 insertions(+), 3 deletions(-) create mode 100644 src/mongoose_c2s.erl create mode 100644 src/mongoose_c2s_listener.erl diff --git a/rebar.config b/rebar.config index 2bca5f5351..1137250de9 100644 --- a/rebar.config +++ b/rebar.config @@ -78,6 +78,7 @@ %%% HTTP tools {graphql, {git, "https://github.com/esl/graphql-erlang.git", {branch, "master"}}}, + {ranch, "2.1.0"}, {cowboy, "2.9.0"}, {gun, "1.3.3"}, {fusco, "0.1.1"}, diff --git a/rebar.lock b/rebar.lock index 1a31e04263..e07ff4826c 100644 --- a/rebar.lock +++ b/rebar.lock @@ -107,7 +107,7 @@ {<<"proper">>,{pkg,<<"proper">>,<<"1.4.0">>},0}, {<<"quickrand">>,{pkg,<<"quickrand">>,<<"2.0.4">>},1}, {<<"rabbit_common">>,{pkg,<<"rabbit_common">>,<<"3.9.11">>},1}, - {<<"ranch">>,{pkg,<<"ranch">>,<<"1.8.0">>},1}, + {<<"ranch">>,{pkg,<<"ranch">>,<<"2.1.0">>},0}, {<<"re2">>,{pkg,<<"re2">>,<<"1.9.7">>},1}, {<<"recon">>,{pkg,<<"recon">>,<<"2.5.2">>},0}, {<<"redbug">>,{pkg,<<"redbug">>,<<"1.2.1">>},1}, @@ -186,7 +186,7 @@ {<<"proper">>, <<"89A44B8C39D28BB9B4BE8E4D715D534905B325470F2E0EC5E004D12484A79434">>}, {<<"quickrand">>, <<"168CA3A8466A26912B8C3A1D6AA58975E1BB49E5C7AFB4998B80F6B90F910490">>}, {<<"rabbit_common">>, <<"25DF900B1AEC7357C90253CC4528B43C5FF064F27C8C627707B747AE986EBF77">>}, - {<<"ranch">>, <<"8C7A100A139FD57F17327B6413E4167AC559FBC04CA7448E9BE9057311597A1D">>}, + {<<"ranch">>, <<"2261F9ED9574DCFCC444106B9F6DA155E6E540B2F82BA3D42B339B93673B72A3">>}, {<<"re2">>, <<"8114654E72EF62F605A8A393F219702F253CB7A02F671503918B76D0614DB046">>}, {<<"recon">>, <<"CBA53FA8DB83AD968C9A652E09C3ED7DDCC4DA434F27C3EAA9CA47FFB2B1FF03">>}, {<<"redbug">>, <<"9153EE50E42C39CE3F6EFA65EE746F4A52896DA66862CFB59E7C0F838B7B8414">>}, @@ -248,7 +248,7 @@ {<<"proper">>, <<"18285842185BD33EFBDA97D134A5CB5A0884384DB36119FEE0E3CFA488568CBB">>}, {<<"quickrand">>, <<"4CB18E9304CF28E054E8DC6E151D1AC7F174E6FE31D5C1A07F71279B92A90800">>}, {<<"rabbit_common">>, <<"1BCAC63760A0BF0E55D7D3C2FF36ED2310E0B560BD110A5A2D602D76D9C08E1A">>}, - {<<"ranch">>, <<"49FBCFD3682FAB1F5D109351B61257676DA1A2FDBE295904176D5E521A2DDFE5">>}, + {<<"ranch">>, <<"244EE3FA2A6175270D8E1FC59024FD9DBC76294A321057DE8F803B1479E76916">>}, {<<"re2">>, <<"FF0703CA095B5BEBF57DD12571AF24B3BA404180E9B5E43128790B5D31EBE803">>}, {<<"recon">>, <<"2C7523C8DEE91DFF41F6B3D63CBA2BD49EB6D2FE5BF1EEC0DF7F87EB5E230E1C">>}, {<<"redbug">>, <<"BFC7BCB8743C55DBE0134DBCB89DD6A57606288CC4E2570ECCD701061FBCBD93">>}, diff --git a/src/mongoose_c2s.erl b/src/mongoose_c2s.erl new file mode 100644 index 0000000000..5922ba9670 --- /dev/null +++ b/src/mongoose_c2s.erl @@ -0,0 +1,55 @@ +-module(mongoose_c2s). + +-behaviour(gen_statem). +-include("mongoose_logger.hrl"). + +%% gen_statem callbacks +-export([callback_mode/0, init/1, handle_event/4]). + +-record(state, { + ref :: reference(), + transport, + socket + }). +-type state() :: #state{}. +-type fsm_res() :: gen_statem:event_handler_result(state()). + +-type retries() :: pos_integer(). +-type stream_state() :: stream_start | authenticated. +-type feature_state() :: before_auth | after_auth. +-type fsm_state() :: connecting + | {wait_for_stream, stream_state()} + | {wait_for_feature, feature_state(), retries()} + | {wait_for_sasl_response, retries()} + | session_established + | resume_session. + +-export_type([state/0]). + +%%%---------------------------------------------------------------------- +%%% gen_statem +%%%---------------------------------------------------------------------- +-spec callback_mode() -> gen_statem:callback_mode_result(). +callback_mode() -> + handle_event_function. + +-spec init({ranch:ref(), module(), map()}) -> gen_statem:init_result(state()). +init({Ref, Transport, Opts}) -> + StateData = #state{ref = Ref, transport = Transport}, + gen_statem:cast(self(), connect), + {ok, connecting, StateData}. + +-spec handle_event(gen_statem:event_type(), term(), fsm_state(), state()) -> fsm_res(). +handle_event(cast, connect, connecting, StateData = #state{ref = Ref, transport = Transport}) -> + {ok, Socket} = ranch:handshake(Ref), + Transport:setopts(Socket, [{active, once}]), + NewState = StateData#state{socket = Socket}, + {next_state, {wait_for_stream, stream_start}, NewState};

From 4ef90fbcd554d612e1306ec6cb28647b8f74679e Mon Sep 17 00:00:00 2001 From: Nelson Vides Date: Mon, 30 May 2022 15:40:27 +0200 Subject: [PATCH 02/56] Implement a new barebones c2s process The flow is as follows: init casts a `connect` message, to indicate the process that it needs to establish the tcp connection, outside of the init function that blocks the supervisor. Then all states are handled in a single handle_event. The event connect in state connecting indicates to end negotiating the connection. The event info with payload from tcp or ssl, regardless of the state, simply parses the payload using exml_stream, and adds all parsed packets as internal action events of the OTP's gen_statem behaviour, that is, they will be processed immediately as the next event in the state machine, without involved message passing. Then, as internal events, all packets are processed, according to their running state machine state. One specific event is expected in that state, and an appropriate handle_* helper does the work. States can be compound, so now instead of sticking data of a specific state into the state-machine memory, we can make it part of the state itself, and it will be used in the next event in that state, see `{wait_for_feature, after auth, _}` and `{wait_for_feature, before_auth, _}`. Code that specifies stanzas is moved to a helper module that construct all the verbose #xmlel{} packets, to keep the c2s module smaller and separate protocol from state machine. --- src/mongoose_c2s.erl | 458 ++++++++++++++++++++++++++++++++++- src/mongoose_c2s_stanzas.erl | 120 +++++++++ src/mongoose_hooks.erl | 13 +- 3 files changed, 578 insertions(+), 13 deletions(-) create mode 100644 src/mongoose_c2s_stanzas.erl diff --git a/src/mongoose_c2s.erl b/src/mongoose_c2s.erl index 5922ba9670..cb289e44e9 100644 --- a/src/mongoose_c2s.erl +++ b/src/mongoose_c2s.erl @@ -2,19 +2,36 @@ -behaviour(gen_statem). -include("mongoose_logger.hrl"). +-include("mongoose.hrl"). +-include("jlib.hrl"). +-include_lib("exml/include/exml_stream.hrl"). +-define(C2S_OPEN_TIMEOUT, 60000). +-define(AUTH_RETRIES, 3). +-define(BIND_RETRIES, 5). %% gen_statem callbacks --export([callback_mode/0, init/1, handle_event/4]). +-export([callback_mode/0, init/1, handle_event/4, terminate/3]). + +%% utils +-export([filter_mechanism/1]). -record(state, { - ref :: reference(), - transport, - socket + host_type = <<>> :: mongooseim:host_type(), + lserver = <<>> :: jid:lserver(), + jid :: undefined | jid:jid(), + sid = ejabberd_sm:make_new_sid() :: ejabberd_sm:sid(), + sasl_state :: cyrsasl:sasl_state(), + streamid = new_stream_id() :: binary(), + ranch_ref :: ranch:ref(), + transport :: module(), + socket :: ranch_transport:socket(), + parser :: undefined | exml_stream:parser() }). -type state() :: #state{}. --type fsm_res() :: gen_statem:event_handler_result(state()). +-type maybe_ok() :: ok | {error, atom()}. +-type fsm_res() :: gen_statem:event_handler_result(fsm_state(), state()). --type retries() :: pos_integer(). +-type retries() :: 0..64. -type stream_state() :: stream_start | authenticated. -type feature_state() :: before_auth | after_auth. -type fsm_state() :: connecting @@ -33,23 +50,440 @@ callback_mode() -> handle_event_function. --spec init({ranch:ref(), module(), map()}) -> gen_statem:init_result(state()). -init({Ref, Transport, Opts}) -> - StateData = #state{ref = Ref, transport = Transport}, +-spec init({ranch:ref(), module(), mongoose_listener:options()}) -> + gen_statem:init_result(fsm_state(), state()). +init({Ref, Transport, _Opts}) -> + StateData = #state{ranch_ref = Ref, transport = Transport}, gen_statem:cast(self(), connect), {ok, connecting, StateData}. -spec handle_event(gen_statem:event_type(), term(), fsm_state(), state()) -> fsm_res(). -handle_event(cast, connect, connecting, StateData = #state{ref = Ref, transport = Transport}) -> +handle_event(cast, connect, connecting, StateData = #state{ranch_ref = Ref, transport = Transport}) -> {ok, Socket} = ranch:handshake(Ref), Transport:setopts(Socket, [{active, once}]), - NewState = StateData#state{socket = Socket}, + {ok, NewParser} = exml_stream:new_parser([{max_child_size, 65536}]), + NewState = StateData#state{socket = Socket, parser = NewParser}, {next_state, {wait_for_stream, stream_start}, NewState};

Note that dialyzer might not be strong enough to identify this polymorphism, but it might probably be in the future, as well as different tools like Gradualizer. Also mongoose_acc uses erlang:system_time/1 instead of the os equivalent, to better resist time warps and also for performance, and likewise such time is later used to calculate a metric for the time the message took to be handled. Now, all c2s handling stanzas will be captured and handled in hooks, and mongoose_acc will be a universal accumulator. --- src/gen_hook.erl | 16 ++-- src/metrics/mongoose_metrics_definitions.hrl | 4 +- src/mongoose_acc.erl | 2 +- src/mongoose_c2s.erl | 84 +++++++------------- src/mongoose_hooks.erl | 49 ++++++++++-- 5 files changed, 85 insertions(+), 70 deletions(-) diff --git a/src/gen_hook.erl b/src/gen_hook.erl index 5125f3e234..f3d4ac35ba 100644 --- a/src/gen_hook.erl +++ b/src/gen_hook.erl @@ -42,15 +42,17 @@ -type key() :: {HookName :: atom(), Tag :: any()}. --type hook_tuple() :: {HookName :: hook_name(), - Tag :: hook_tag(), - Function :: hook_fn(), - Extra :: hook_extra(), - Priority :: pos_integer()}. +-type hook_tuple() :: hook_tuple(hook_fn()). +-type hook_tuple(HookFn) :: {HookName :: hook_name(), + Tag :: hook_tag(), + Function :: HookFn, + Extra :: hook_extra(), + Priority :: pos_integer()}. --type hook_list() :: [hook_tuple()]. +-type hook_list() :: hook_list(hook_fn()). +-type hook_list(HookFn) :: [hook_tuple(HookFn)]. --export_type([hook_fn/0, hook_list/0]). +-export_type([hook_fn/0, hook_list/0, hook_list/1]). -record(hook_handler, {prio :: pos_integer(), hook_fn :: hook_fn(), diff --git a/src/metrics/mongoose_metrics_definitions.hrl b/src/metrics/mongoose_metrics_definitions.hrl index 3da2a14075..3ff9208895 100644 --- a/src/metrics/mongoose_metrics_definitions.hrl +++ b/src/metrics/mongoose_metrics_definitions.hrl @@ -71,7 +71,9 @@ [data, xmpp, received, xml_stanza_size], [data, xmpp, sent, encrypted_size], [data, xmpp, sent, compressed_size], - [data, xmpp, sent, xml_stanza_size]]). + [data, xmpp, sent, xml_stanza_size], + [data, xmpp, sent, message, processing_time] + ]). -define(DATA_FUN_METRICS, [{[data, dist], diff --git a/src/mongoose_acc.erl b/src/mongoose_acc.erl index 1f91212dd3..fd72d6f00d 100644 --- a/src/mongoose_acc.erl +++ b/src/mongoose_acc.erl @@ -131,7 +131,7 @@ new(#{ location := Location, lserver := LServer } = Params) -> #{ mongoose_acc => true, ref => make_ref(), - timestamp => os:system_time(microsecond), + timestamp => erlang:system_time(microsecond), origin_pid => self(), origin_location => Location, stanza => Stanza, diff --git a/src/mongoose_c2s.erl b/src/mongoose_c2s.erl index 59778a2396..3378dd4351 100644 --- a/src/mongoose_c2s.erl +++ b/src/mongoose_c2s.erl @@ -12,7 +12,7 @@ -export([callback_mode/0, init/1, handle_event/4, terminate/3]). %% utils --export([filter_mechanism/1]). +-export([get_sid/1, get_jid/1, filter_mechanism/1]). -record(state, { host_type = <<>> :: mongooseim:host_type(), @@ -30,6 +30,8 @@ -type state() :: #state{}. -type maybe_ok() :: ok | {error, atom()}. -type fsm_res() :: gen_statem:event_handler_result(fsm_state(), state()). +-type handler_params() :: #{c2s := mongoose_c2s:state()}. +-type handler_fn() :: fun( (mongoose_acc:t(), handler_params(), map() ) -> mongoose_acc:t()). -type retries() :: 0..64. -type stream_state() :: stream_start | authenticated. @@ -41,7 +43,7 @@ | session_established | resume_session. --export_type([state/0]). +-export_type([state/0, handler_params/0, handler_fn/0]). %%%---------------------------------------------------------------------- %%% gen_statem @@ -400,43 +402,34 @@ verify_from(El, StateJid) -> jid:are_equal(jid:from_binary(SJid), StateJid) end. -handle_c2s_packet(StateData, El) -> +handle_c2s_packet(StateData = #state{host_type = HostType}, El) -> Acc0 = element_to_origin_accum(StateData, El), - Acc1 = mongoose_hooks:c2s_preprocessing_hook(StateData#state.host_type, Acc0, StateData), + Acc1 = mongoose_hooks:c2s_preprocessing_hook(HostType, Acc0, StateData), case mongoose_acc:get(hook, result, undefined, Acc1) of drop -> {next_state, session_established, StateData};
