connections are never closed #11

ibrowse never timesout on a open connection if the server never closes the connection.
This will cause an application that connects to several different domains to eventually exhaust all file descriptors.

I suggest the use of some sort of argument to explicitly pass a timeout in seconds or infinity to a send_req.
The connection should be closed after the timeout has expired.


Have you tried using the inactivity_timeout option?


no I haven't where and how should I set this option?


It was supposed to be used like this.

ibrowse:send_req(Host, Port, Method, Headers, [{inactivity_timeout, 5000} | Other_options]).

But it only works if a request is in progress. But that is a bit silly, it should work even if all requests on that connection are done and the connection is idle. I'll make a patch and let you know. Thanks for reporting it.


Here is a patch against ibrowse-2.0.1

The connection will close after 10 seconds of inactivity on the connection. You can control this timeout value by the ibrowse application variable inactivity_timeout (either set in or your sys.config file)


The updated patch at the link below supports specifying this config in ibrowse.conf as well.


I'll give it a try. thanks


I applyed your patch but I get this error:

** When Server state == undefined
** Reason for termination == 
** {function_clause,[{ibrowse_http_client,do_close,[undefined]},

looks like the state is being set to undefined somewhere.


I added this two lines to the set_inac_timer/2 to solve the problem:

+set_inac_timer(State, infinity) ->
+    State;

After some debugging I noticed that get_inac_timeout/1 was returning infinity and that would cause set_inac_timer/2 to return 'undefined'.

let me know if this is the right way to solve the problem.


That's great, thanks very much. I'll commit it soon...


It works thanks.
