#
# CBL : Curl Benchmark on Lodel
#
# Usage : $0 [HOSTNAME] [INSTANCE_LIST_FILE] [N_CREATE] [N_EDIT] [N_DELETE]
#
# Instance_list_file is expected to be a file containing instances name (1 per
# line). Uses by default /tmp/lodel2_instance_list.txt
#
# Instances base URL are generated given the current webui implementation :
# http://HOST/INSTANCE_NAME/
#
#
# Scenario description :
#
# mass_creation instance_name iteration_count :
#	Create iteration_count time a random leobject in given instance_name
#	note : do note create relation between objects, only populate content
#	
#	step 1 : fetch all non abstract class name
# 	step 2 : loop on creation (using bash function curl_opt_create_CLSNAME)
#		that return the POST fields (populated with random values)
#
# mass_get instance_name :
#	Create all possible get for an instance
#	step 1 : fetch all classes
#	step 2 : for each class fetch all id
#	step 3 : for all ids generate the gets
#
# mass_deletion instance_name iteration_count :
#	Foreach non asbtracty class delete iteration_count time an object of
#	current class in current instance
#
#	step 1 : fetch all non abstract class name
#	step 2 : loop on non abstract class name
#	step 3 : loop iteration_count time on deletion
#
# mass_link_edit instance_name iteration_count :
#	Foreach non abstract class make iteration_count time edition of an
#	object in current class
#	note : only implemented for Person for the moment
#	note : can maybe ask for invalid modifications
#
#	step 1 : fetch all non abstract class name
#	step 2 : loop on non abstract class name
#	step 3 : depends on curent class :
#		- fetch all existing id of current class
#		- fetch all existing id in class that can be linked with
#		  current class
#	step 4 : loop iteration_count time :
#		- choose a random id in current class
#		- choose random ids from linkable classes
#		- trigger edition using curl (with datas from the same
#		  bash function than creation : curl_opt_create_CLSNAME)
#
# Current way to run scenarios :
#
# using the function run_bg_with_param FUNCTION_NAME INSTANCE_LIST_FILE *ARGS
#
# The function name can be one of the scenario functions
# INSTANCE_LIST_FILE is the file containing instances list
# *ARGS are args given as it to FUNCTION_NAME after the instance_name argument
#
# function call : FUN_NAME INSTANCE_NAME *ARGS
#
# The run_bg_with_param run a scenario in background for each instance allowing
# to send a lot of request at the same time
#
