-%%
-%% 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,

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.

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.
