Exception: In event detail and select event is null
Hi all,
I configured faban/olio to run a performance test with Ruby version of Olio.
When I run the performance test I get this warning (and the
IOException) in the faban Run Log:
UIDriverAgent[0].1.doEventDetail: In event detail and select event is null
Trace:
org.apache.olio.workload.driver.UIDriver doEventDetail 656
sun.reflect.GeneratedMethodAccessor6 invoke
sun.reflect.DelegatingMethodAccessorImpl invoke 25
java.lang.reflect.Method invoke 597
com.sun.faban.driver.engine.TimeThread doRun 169
com.sun.faban.driver.engine.AgentThread run 202
Once the test is completed I see that lot of (39 out of 91)
"EventDetail" operations are failed (this is a small test run - so
the numbers are small)
What might be the cause of this problem ?
How does this affect the results, in the sense of throughput and response time ?
Thanks in advance

So basically, during development, none of the GET requests would ever
redirect, except on the rare occasions that the routing issue showed up.
Writing drivers is a bit of an art, and I've often used the technique of
having setFollowRedirects(true) by default and disabling it when I hit a
POST. If this solves the problems, send me a patch and I'll integrate it.
Thanks

Yeah. I had problem with POSTs. Sorry I forgot to tell that one. I had to do :
enable follow redirect
do the / request
disable follow redirect
I guess it's sort of a hack.

Actually I am using thin and rack with nginx.
thin (1.2.7)
rack (1.0.1)

http.setFollowRedirects(true) never used to work for POST requests so they
had to be handled manually. Obviously the update to HttpClient 3.1 changed
that, and yes I could only test on a limited number of setups, and I
favoured Thin and Rack (although I also tested with mod_rails (Passenger)
and Lighttpd).
I'm going to try to port the WebApp to 1.9.2 over the holidays. At the very
least I'll recheck the app and driver on Linux and make sure that everything
works.

Re: Exception: In event detail and select event is null
Posted by Sahan Gamage <sa...@gmail.com>.
I was able to track down what happens to some more details:
When a user sends a request to root ("/"). router has a rule to
redirect it to events:index.
In the events_controller where index is handled, the request is
checked to see whether it is a request by a logged in user (by
checking the session id).
If it is a request by a logged in user, a redirect is done to /home
(redirect_to(home_path)). This is where thin outputs 302 status with
"You are being redirected" message. From what I read about rails
redirects this behavior seems correct
(http://rails.rubyonrails.org/classes/ActionController/Base.html#M000468).
I am not sure why it has not occurred before to anybody when doing
testing (may be my environment is still not exactly as expected to
be).
Anyways, what I did to fix this was enable setFollowRedirects in http
client at the OlioDriver (http.setFollowRedirects(true)). I am not
sure this is the perfect solution. But so far it is working for me.

Re: Exception: In event detail and select event is null

It's likely to be a Rails routing issue, I had a few random occurrences of
this but it always went away when I investigated. Take a look at
http://www.tutorialspoint.com/ruby-on-rails-2.1/rails-routes.htm for an
insight into how routing works. You should be able to figure out whey the
redirect is happening on your setup.

Re: Exception: In event detail and select event is null
Posted by Sahan Gamage <sa...@gmail.com>.
Thanks for the quick reply.
Here are some details of the system:
OS: Ubuntu 9.04
Ruby : 1.8.7
Rails : 2.3.5
proxy : nginx 0.6.35
I did some more digging into the problem and I logged the entire html
page when the exception occurs (doEventDetail) in UIDriver.java. It
seems like server sends a redirection message (<html><body>You are
being <a href="http://10.0.100.176/home">redirected</a>.</body></html>)
and that's why it fails to scrape an event from the html.
I am looking into this one
If you have seen this before and know a quick fix pls let me know.
Thanks a lot

It means that the driver was unable to scrape an Event ID from the HomePage
which itself suggests that the HomePage wasn't rendered correctly. What
version of Ruby? What version of Rails? What OS? Is there anything in the
logs? If not and you are running in production you might want to run in
development mode and run a smaill test and observe what happens when
EventDetail fails.
We still only support Ruby 1.8.7 and Rails 2.3.5
Thanks
