-%% 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

+-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.

+
+-module(inviso_tool_sh).
+
+%% 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.
