-%% The inviso_tool implementation. A tool that uses inviso.
-%%

-%% -----------------------------------------------------------------------------
-
--module(inviso_tool).
-
-
-%% This is the inviso tool, which is a tool using the inviso trace application.
-%% It is developed to make tracing using trace cases possible in an environment
-%% of distributed Erlang nodes.
-%% A current restriction is that the Erlang nodes are supposed to have the same
-%% code. This since inviso tool can at this point not handle subsets of nodes.
-%% Instead all participating Erlang nodes are treated the same.
-%%
-%% The main functionality of the inviso tool are:
-%%
-%% (1) Handles start and stop of tracing at participating nodes.
-%% (2) Interprets trace-case files at a distributed network level.
-%% (The inviso runtime component is responsible for interpreting
-%% trace cases at a local level, if run in an autostart).
-%% (3) Keeps a command history log from which:
-%% (a) Sequences easily can be repeated.
-%% (b) Autostart configuration files can be created (understood by the
-%% default inviso autostart mechanism).
-%% (4) Performs reactivation in case tracing is suspended (manually or by
-%% an overload mechanism).
-%% (5) Can reconnect crashed nodes and by using the history bringing them
-%% up to speed.
-
-%% Distributed Erlang
-%% ------------------
-%% Inviso is built to run in a distributed environment.
-%% The inviso tool can also be used in a non distributed environment.
-
-%% Short description
-%% -----------------
-%% Start-up of the inviso tool
-%% During the start-up of the tool, the tool starts runtime components at
-%% all participating nodes. A runtime component can already be running at
-%% a particular node and will then simply be adopted.
-%%
-%% Session
-%% A session is said to start when tracing is initiated, and ends when
-%% made to stop by the user. When a session is stopped, tracing is stopped
-%% at all participating nodes. Note that participating nodes may come and
-%% go though the time-frame of a session. That means that if a node is
-%% reconnected it may resume its tracing in the current session through
-%% a 'restart_session'. A runtime component that is already tracing at the
-%% time start-session will simply be part of the session without its
-%% ingoing tracing being changed.
-%%
-%% Reactivation
-%% A node that is suspended can be reactivated to resume tracing. Note that
-%% tracing has in this situation never been stopped at the node in question.
-%% The inviso tool resumes the node and applies the history to it.
-%%
-%% Reconnect
-%% A node that is "down" from the inviso tool's perspective can be
-%% reconnected. During reconnection the tool restarts the runtime component
-%% at that node but does not (re)initiate tracing. The latter is called
-%% restart_session and must be done explicitly, unless the node in question
-%% is in fact already tracing. If the node is already tracing (due to an autostart
-%% for instance), it automatically becomes part of the ongoing session (if
-%% there is an ongoing session).
-%%
-%% Restart Session
-%% A node that has been down and has been reconnected can be made to
-%% initialize and resume its tracing. This is done by starting the session
-%% at the node in question and redoing the current history.
-
-%% Trace files within a session
-%% Since it is possible to init-tracing (from an inviso perspective) several
-%% times within the same session, a session may leave several trace log files
-%% behind. This must be resolved by the tracer data generator function
-%% (user supplied) by marking filenames in a chronological order but still
-%% making them possible to identify as part of the same session

A tool that uses inviso. +%% +%% Authors: +%% Lennart Öhman, [email protected] +%% ----------------------------------------------------------------------------- + +-module(inviso_tool). + + +%% This is the inviso tool, which is a tool using the inviso trace application. +%% It is developed to make tracing using trace cases possible in an environment +%% of distributed Erlang nodes. +%% A current restriction is that the Erlang nodes are supposed to have the same +%% code. This since inviso tool can at this point not handle subsets of nodes. +%% Instead all participating Erlang nodes are treated the same. +%% +%% The main functionality of the inviso tool are: +%% +%% (1) Handles start and stop of tracing at participating nodes. +%% (2) Interprets trace-case files at a distributed network level. +%% (The inviso runtime component is responsible for interpreting +%% trace cases at a local level, if run in an autostart). +%% (3) Keeps a command history log from which: +%% (a) Sequences easily can be repeated. +%% (b) Autostart configuration files can be created (understood by the +%% default inviso autostart mechanism). +%% (4) Performs reactivation in case tracing is suspended (manually or by +%% an overload mechanism). +%% (5) Can reconnect crashed nodes and by using the history bringing them +%% up to speed. + +%% Distributed Erlang +%% ------------------ +%% Inviso is built to run in a distributed environment. +%% The inviso tool can also be used in a non distributed environment. + +%% Short description +%% ----------------- +%% Start-up of the inviso tool +%% During the start-up of the tool, the tool starts runtime components at +%% all participating nodes. A runtime component can already be running at +%% a particular node and will then simply be adopted. +%% +%% Session +%% A session is said to start when tracing is initiated, and ends when +%% made to stop by the user. When a session is stopped, tracing is stopped +%% at all participating nodes. Note that participating nodes may come and +%% go though the time-frame of a session. That means that if a node is +%% reconnected it may resume its tracing in the current session through +%% a 'restart_session'. A runtime component that is already tracing at the +%% time start-session will simply be part of the session without its +%% ingoing tracing being changed. +%% +%% Reactivation +%% A node that is suspended can be reactivated to resume tracing. Note that +%% tracing has in this situation never been stopped at the node in question. +%% The inviso tool resumes the node and applies the history to it. +%% +%% Reconnect +%% A node that is "down" from the inviso tool's perspective can be +%% reconnected. During reconnection the tool restarts the runtime component +%% at that node but does not (re)initiate tracing. The latter is called +%% restart_session and must be done explicitly, unless the node in question +%% is in fact already tracing. If the node is already tracing (due to an autostart +%% for instance), it automatically becomes part of the ongoing session (if +%% there is an ongoing session). +%% +%% Restart Session +%% A node that has been down and has been reconnected can be made to +%% initialize and resume its tracing. This is done by starting the session +%% at the node in question and redoing the current history. + +%% Trace files within a session +%% Since it is possible to init-tracing (from an inviso perspective) several +%% times within the same session, a session may leave several trace log files +%% behind. This must be resolved by the tracer data generator function +%% (user supplied) by marking filenames in a chronological order but still +%% making them possible to identify as part of the same session + + + +%% ----------------------------------------------------------------------------- +%% API exports. +%% ----------------------------------------------------------------------------- + +-export([start/0,start/1,stop/0,stop/1]). +-export([reconnect_nodes/0,reconnect_nodes/1, + start_session/0,start_session/1, + reinitiate_session/0,reinitiate_session/1, + restore_session/0,restore_session/1,restore_session/2, + stop_session/0, + reset_nodes/0,reset_nodes/1, + atc/3,sync_atc/3,sync_atc/4, + sync_rtc/2,sync_rtc/3, + dtc/2,sync_dtc/2,sync_dtc/3, + inviso/2]). +-export([reactivate/0,reactivate/1, + save_history/1, + get_autostart_data/1,get_autostart_data/2, + get_activities/0,get_node_status/0,get_node_status/1,get_session_data/0]). +-export([flush/0,flush/1]). +%% ----------------------------------------------------------------------------- + +%% ----------------------------------------------------------------------------- +%% Debug exports. +%% ----------------------------------------------------------------------------- + +-export([get_loopdata/0]). +%% ----------------------------------------------------------------------------- + +%% ----------------------------------------------------------------------------- +%% OTP exports and call backs. +%% ----------------------------------------------------------------------------- + +-export([init/1,handle_call/3,handle_cast/2,handle_info/2,terminate/2]). +%% ----------------------------------------------------------------------------- + +%% ----------------------------------------------------------------------------- +%% Internal exports. +%% ----------------------------------------------------------------------------- + +-export([tc_executer/4,reactivator_executer/6]). +-export([std_options_generator/1]). +%% ----------------------------------------------------------------------------- + +%% ----------------------------------------------------------------------------- +%% Constants. +%% ----------------------------------------------------------------------------- + +%% Defines the inviso function calls that shall be possible to do through the +%% inviso API in this tool. +-define(INVISO_CMDS, + [{tp,5},{tp,4},{tp,1},{tpl,5},{tpl,4},{tpl,1}, + {ctp,1},{ctp,2},{ctp,3},{ctpl,1},{ctpl,2},{ctpl,3}, + {tf,2},{tf,1},{ctf,2},{ctf,1},{ctf_all,0}, + {init_tpm,4},{init_tpm,7}, + {tpm,4},{tpm,5},{tpm,8}, + {tpm_tracer,4},{tpm_tracer,5},{init_tpm,8}, + {tpm_ms,5},{tpm_ms_tracer,5}, + {ctpm_ms,4},{ctpm,3}, + {tpm_localnames,0},{ctpm_localnames,0}, + {tpm_globalnames,0},{ctpm_globalnames,0}, + {ctp_all,0}, + {suspend,1},{cancel_suspension,0}]). +%% ----------------------------------------------------------------------------- + +%% These inviso functions shall be included in the command history log.

-%% Inviso Session Handler.
-%% This is the code for the session handler process. Its purpose is that we have
-%% one session handler process for each trace session started through the
-%% start_session inviso tool API. The session handler process is responsible for:
-%%
-%% -Knowing the state/status of all participating runtime components.
-%% -Keeping storage of all tracerdata all our participants have used. This means
-%% also to find out the tracerdata of runtime components connecting by them
-%% selves.
-%%
-%% STORAGE STRATEGY
-%% ----------------
-%% The local information storage can be changed by two things. Either by executing
-%% commands issued through our APIs. Or by receiving trace_event from the control
-%% component. When we execute commands, a corresponding event will also follow.
-%% Meaning that in those situations we are informed twice.
-%% A simple strategy could be to wait for the event even when doing the changes
-%% to the runtime components our self (through commands). But that may result in
-%% a small time frame where someone might do yet another command and failing
-%% because the local information storage is not uptodate as it would have been
-%% expected to be. Therefore we always update the local storage when making changes
-%% to a runtime component our selves. There will eventually be a double update
-%% through an incoming event. But the storage must coop with that, preventing
-%% inconsitancies to happend. An example of a strategy is that the tracerdata table
-%% is a bag, not allowing for double entries of the same kind. Therefore a double
-%% update is harmless there.

Its purpose is that we have +%% one session handler process for each trace session started through the +%% start_session inviso tool API. The session handler process is responsible for: +%% +%% -Knowing the state/status of all participating runtime components. +%% -Keeping storage of all tracerdata all our participants have used. This means +%% also to find out the tracerdata of runtime components connecting by them +%% selves. +%% +%% STORAGE STRATEGY +%% ---------------- +%% The local information storage can be changed by two things. Either by executing +%% commands issued through our APIs. Or by receiving trace_event from the control +%% component. When we execute commands, a corresponding event will also follow. +%% Meaning that in those situations we are informed twice. +%% A simple strategy could be to wait for the event even when doing the changes +%% to the runtime components our self (through commands). But that may result in +%% a small time frame where someone might do yet another command and failing +%% because the local information storage is not uptodate as it would have been +%% expected to be. Therefore we always update the local storage when making changes +%% to a runtime component our selves. There will eventually be a double update +%% through an incoming event. But the storage must coop with that, preventing +%% inconsitancies to happend. An example of a strategy is that the tracerdata table +%% is a bag, not allowing for double entries of the same kind. Therefore a double +%% update is harmless there. + +%% ------------------------------------------------------------------------------ +%% Module wide constants. +%% ------------------------------------------------------------------------------ +-define(LOCAL_RUNTIME,local_runtime). % Used as node name when non-disitrbuted. +-define(TRACING,tracing). % A state defined by the control component. +-define(RUNNING,running). % A status according to control componet. + +-define(COPY_LOG_FROM,copy_log_from). % Common fileystem option. +%% ------------------------------------------------------------------------------ + +%% ------------------------------------------------------------------------------ +%% API exports. +%% ------------------------------------------------------------------------------ +-export([start_link/5,start_link/8]). +-export([cancel_session/1,stop_session/3]). +-export([reactivate/1,reactivate/2]). +-export([ctpl/5,tpl/5,tpl/6,tpl/7, + tf/2,tf/3, + tpm_localnames/2,init_tpm/6,init_tpm/9,tpm/6,tpm/7,tpm/10, + tpm_ms/7,ctpm_ms/6,ctpm/5 + ]). +%% ------------------------------------------------------------------------------ + + +%% ------------------------------------------------------------------------------ +%% Internal exports. +%% ------------------------------------------------------------------------------ +-export([init/1,handle_call/3,handle_info/2,terminate/2]). + +-export([get_loopdata/1]). +%% ------------------------------------------------------------------------------ + + +%% ------------------------------------------------------------------------------ +%% Includes. +%% ------------------------------------------------------------------------------ +-include_lib("kernel/include/file.hrl"). % Necessary for file module. +%% ------------------------------------------------------------------------------ + + +%% ============================================================================== +%% Exported API functions. +%% ============================================================================== + +%% start_link(From,NodeParams,CtrlNode,CtrlPid,SafetyCatches,NodesIn,NodesNotIn) = +%% {ok,Pid} | {error,Reason} +%% From= pid(), the initial client expecting the reply. +%% NodeParams=[{Node,TracerData},{Node,TracerData,Opts}...] +%% CtrlNode=atom() | 'void', the node where the trace control component is. +%% CtrlPid=pid(), the pid of the trace control component. +%% SafetyCatches= +%% Dir=string(), where to place fetched logs and the merged log. +%% Dbg=debug structure. +%% NodesIn=[Node,...], list of nodes already in another session. +%% NodesNotIn=[Node,...], list of nodes not in another session. +%% +%% Starts a session-handler.
