Scheduler and Rake Tasks

[April]

Hello,

I seem to be having trouble getting scheduler to run a rake task
repeatedly. It will run fine the first time, and the it won't run
again (the scheduler does run again, just the rake task seems not
to). The rake task seems to work just fine when I run it from the
console.

Any help would be much appreciated.

Thanks,
April

-------------------------
/config/initializers/rask_scheduler.rb

require 'rake'
load File.join( RAILS_ROOT, 'lib', 'tasks', 'emails.rake')
require 'rubygems'
require 'rufus/scheduler'

scheduler = Rufus::Scheduler.start_new

scheduler.every("1m") do
puts 'Scheduler is running'
Rake::Task["emails:send_queue"].invoke
end

--------------------------
/lib/tasks/email.rake

namespace :emails do

desc "Recurring email send"
task(:send_queue) do

puts 'send email'

end
end

Hello April,

ruby version ? rails version ? server (mongrel / thin / passenger) ?
rufus-scheduler version ? Are you running it along with EventMachine ?

No error message appearing on the console ?

Did you try things like specifying a custom exception handler ?

---8<---
def scheduler.handle_exception (job, exception)
puts "job #{job.job_id} caught exception '#{exception}'"
end
--->8---

Best regards,

Thanks for the quick response. 

Ruby version 1.8.6
Rails version 2.3.2
Server: mongrel (or webrick - I'm running instantrails for my development server)
Rufus-scheduler 2.0.1

No error message on the console.  I tried the custom exception handler you suggested, but since it seems there are no errors, nothing came up (at least that seems like the reasonable explanation to me).

Cheers,
April

Does the pattern "run once, then fail" always hold ?
Does the message "scheduler is running" only print once ?

Does running the rake task from the command line work ? Maybe you have
so sample output.

Yes, it does always hold, and "scheduler is running" only prints once.

Running from command line works every time.

Not sure what you mean by sample output?

Just a STDOUT dump, but I have enough info from your answers, it's OK
for now, thanks.

Instantrails == windows ?
Does it work on a production equivalent environment ?

Could we say that it's not running on Windows but it's running on Linux ?
