-%% start(Options)={ok,pid()}|{error,Reason} 

-%%   Options=[Option,...], the options will be default options to runtime components

-%% Description: The controlling part of the trace tool Inviso
-%%
-%% This code implements the inviso control component meant to be run on an Erlang
-%% node doing any tracing. It can also be used in a non distributed system where
-%% the control component and the runtime component will run on the same virtual
-%% machine.
-%% The control component is not meant to be started by a supervisor but rather
-%% directly by the user when needed.
-%% This module does not provide any APIs to users. Those are found in inviso.erl.
-%% This module merly has the gen_server call-backs.

-%% INVISO LogFile Merger.

-%%

-%% Merges all log-entries in all files in Files in chronological order

-%% into what ever is handled by WorkHandlerFun. Note that Files can contain

-%% several files. Both in the sence that it can be a wrapset. But also because

-%% the log is spread over more than one LogFiles (i.e trace_log + ti_log).

-%% It is further possible to use another reader-process (for the logfiles)

-%% than the default one. This is useful if the logfiles are formatted in

-%% another way than as done by a trace-port.

-%% INVISO LogFileMerger TracePort File READER.

-%%

-%% This module implements a reader process capable of reading traceport files

-%% and feeding them according to the logfile merger process message protocoll

-%% to the logfile merger process.

-%% This module can also serve as example for writing file readers for other

-%% file formats.

-%%

-%% A reader process must:

-%%   Support the reader-receiver protocoll.

-%%     receive next_entry message: {get_next_entry,ReceiverPid}

-%%     recieve stop message should the receiver wish to quit: {stop,ReceiverPid}.

-%%     send next_entry message, either with entry or fault-code.

-%%       next_entry message contains:{next_entry,self(),PidMappings,Timestamp,Term}

-%%                                   {next_entry,self(),Error}

-%%     recognize receiver termination (EXIT-signal).

-%%  Understand logfile structure, both filename structure and content.

-%%  Understand content (log-entry) details to extract the entry and entry

-%%    components as timestamp and originating pid (to make pid-mappings).

-%%  Understand any trace information files (ti).

-%%

-%%  The logfile structure written by inviso_rt_meta is:

-%%    {Pid,Alias,Op,TimeStamp} where:

-%%      Pid=pid(), if Alias==unalias: pid()|other_than_pid()

-%%      Op=alias|unalias,

-%%      TimeStamp=now()

-%% Description:
-%% The inviso_tool implementation. 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

-%% 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.
