[Tsung] Use of ts_file_server for input data stream

[Pentti Kavanagh]

Hi,

I'm trying out Tsung for the first time and have a query regarding the
use of ts_file_server.  I have a csv file from which I'm reading user
and account ids.   I would like to use the data from a single row
multiple times within a session.  To get round this I have added a
get_current_line() method to ts_file_server, so I now have something
like this in my readcsv function:-

user(Pid) -> 
	{ok,Line} = ts_file_server:get_next_line(), 
    [Username, Passwd, Account] = string:tokens(Line,";"),"tbxUser=" ++
Username ++ "&tbxPwd=" ++ Passwd.

currentaccount(Pid) ->
    {ok,Line} = ts_file_server:get_current_line(), 
    [Username, Passwd, Account] = string:tokens(Line,";"),Account.

Within a session I use user(Pid) to get the login details, and then
currentaccount(Pid) for subsequent substitutions in the same session
where I need the account number.  This seems to work fine, but could
this be done a better way (ie. using dynamic variables for example)?

My sample csv file:-

user1;password;200003377
user2;password;200003378
user3;password;200003379

If my solution is ok, then maybe it would be worth including
get_current_line() in ts_file_server as a standard feature.

This is a great project, keep up the good work.

Pentti.
