Acts_as_solr: Starting solr server on windows


I was using acts_as_searchable for one of my project, which uses Hyperestraier in background. Yesterday I decided to use acts_as_solr which uses solr(based on Lucene Java search library). I did all written in its Manual/Readme, but when I issued

to start the solr server, it threw a heart breaking “Bad file descriptor” error, although acts_as_solr was working fine on one of my colleague’s linux machine.

I started digging around this and found that there is an issue in rake task that starts the solr server. Actually the problem was this rake task uses ‘fork’ which is not available on windows, also it only handles ‘ECONNREFUSED’ exception which is actually “Connection Refused” error raised by ruby on linux. But in windown it throws ‘EBADF’ which is “Bad file descriptor” error raised by ruby on windows.

So below is the hack for that:

Just add this to vendor/plugins/acts_as_solr/lib/taks/solr.rake, and start solr server on windows by issuing

This hack didn’t work for me until I renamed the task from :start_win to :startwin. The ‘_’ seems to be a problem in my rails app.

@takemoto: Stop Solr by calling “rake solr:stop”

I tried to work on windows. but whenever I try to run the rake start_win I got the following error “No connection could be made because the target machine actively refused it. - connect(2)”.
My firewall is turned off, so I wonder what may be the problem?

Ahmed,

I had to change Errno::EBADF back to Errno::ECONNREFUSED to make it work on windows. The task tries to send an http request to the server, which isn’t running when you invoke the task, so it catches the excepiton and starts the server. For some reason, the exception being thrown is ECONNREFUSED, not EBADF.
