How to change the Timeout::Error threshold for open_uri

Ruby

When opening a particularly slow loading URL I am getting the following
error:

Loading production environment (Rails 2.0.2)

require ‘open-uri’
=> [“OpenURI”]

?> open(‘WWTDD - Latest Celebrity Gossip and Scandal News’) { |f|
?> puts " Opened successfully with charset: " + f.charset

}

from /usr/lib64/ruby/1.8/irb/workspace.rb:52

Does anyone know how to fix this? I want it to wait longer for the web
server to respond.

Shameless bump. Shoud I be posting on another forum?

Look in the docs/code and you shall find…

OpenURI wraps net/http and net/https

Looking in net/http finds these accessor methods:

# Seconds to wait until connection is opened.
# If the HTTP object cannot open a connection in this many seconds,
# it raises a TimeoutError exception.
attr_accessor :open_timeout

# Seconds to wait until reading one block (by one read(2) call).
# If the HTTP object cannot open a connection in this many seconds,
# it raises a TimeoutError exception.
attr_reader :read_timeout

Maybe that would help.

require ‘net/http’

Lengthen timeout in Net::HTTP

module Net
class HTTP
alias old_initialize initialize

    def initialize(*args)
        old_initialize(*args)
        @read_timeout = 3*60     # 3 minutes
    end
end

end
