## Generic and highly portable bash functions written in 2013-2018 by Orsiris de Jong - http://www.netpower.fr - ozy@netpower.fr

#TODO: ExecTasks postponed arrays / files grow a lot. Consider having them "rolling" (cleaned at numberOfEvents)
#TODO: command line arguments don't take -AaqV for example

####################################################################################################################################################################
## To use in a program, define the following variables:

## PROGRAM=program-name
## INSTANCE_ID=program-instance-name
## _DEBUG=yes/no
## _LOGGER_SILENT=true/false
## _LOGGER_VERBOSE=true/false
## _LOGGER_ERR_ONLY=true/false
## _LOGGER_PREFIX="date"/"time"/""

## Also, set the following trap in order to clean temporary files
## trap GenericTrapQuit TERM EXIT HUP QUIT

## Then simply source ofunctions with
## source "./ofunctions.sh"

## Why use GenericTrapQuit in order to catch exitcode ?
## Logger sets {ERROR|WARN}_ALERT variable when called with critical / error / warn loglevel
## When called from subprocesses, variable of main process cannot be set. Status needs to be get via $RUN_DIR/$PROGRAM.Logger.{error|warn}.$SCRIPT_PID.$TSTAMP

## Main asynchronous execution function
## Function can work in:
## WaitForTaskCompletion mode: monitors given pid in background, and stops them if max execution time is reached. Suitable for multiple synchronous pids to monitor and wait for
## ParallExec mode: takes list of commands to execute in parallel per batch, and stops them if max execution time is reahed.

## Example of improved wait $!
## ExecTasks $! "some_identifier" false 0 0 0 0 true 1 1800 false
## Example: monitor two sleep processes, warn if execution time is higher than 10 seconds, stop after 20 seconds
## sleep 15 &
## pid=$!
## sleep 20 &
## pid2=$!
## ExecTasks "some_identifier" 0 0 10 20 1 1800 true true false false 1 "$pid;$pid2"

## Example of parallel execution of four commands, only if directories exist. Warn if execution takes more than 300 seconds. Stop if takes longer than 900 seconds. Exeute max 3 commands in parallel.
## commands="du -csh /var;du -csh /etc;du -csh /home;du -csh /usr"
## conditions="[ -d /var ];[ -d /etc ];[ -d /home];[ -d /usr]"
## ExecTasks "$commands" "some_identifier" false 0 0 300 900 true 1 1800 true false false 3 "$conditions"

## Bear in mind that given commands and conditions need to be quoted

## ExecTasks has the following ofunctions subfunction requirements:
## Spinner
## Logger
## JoinString
## KillChilds
