Deletes taking to long, just take a break 
(so replication can catch up/things get unblocked)
Only use save sql, there is no escapeing.
class ActiveRecord::Base
def self.slow_delete_all(condition)
count = 0
loop do
result = ActiveRecord::Base.connection.send(:delete_sql, "delete from #{table_name} where #{condition} limit 10000")
count += result
break if result == 0
sleep 1
end
count
end
end
In case you spam a lot of threads and dont know how to get rid of them…
Thread.list.each do |thread| thread.exit unless thread == Thread.current end
Usage
Code
Just built this little snippet in a hacknight, it simulates a geolcation via capybara, so you can test if you geo-magic actually works
View
<p>Finding your location... <span id="status">checking...</span></p>
<script>
jQuery(function () {
var timeout = (document.location.href.indexOf('test_location') >= 0 ? 100 : 0);
setTimeout(function(){
navigator.geolocation.getCurrentPosition(function(){
jQuery('#status').html("found you!");
});
}, timeout)
});
</script>
Capybara test via selenium in rspec
def simulate_location(lat, lng)
page.driver.browser.execute_script <<-JS
window.navigator.geolocation.getCurrentPosition = function(success){
var position = {"coords" : { "latitude": "#{lat}", "longitude": "#{lng}" }};
success(position);
}
JS
end
it "can use location", :js => true do
visit '/?test_location=true'
simulate_location 20, 20
sleep 0.2
page.should have_content "found you!"
end
require ‘resque/tasks’
require ‘resque_scheduler/tasks’
Scheduler needs very little cpu, just start it with a worker.
desc "schedule and work, so we only need 1 dyno"
task :schedule_and_work do
if Process.fork
sh "rake environment resque:work"
else
sh "rake resque:scheduler"
Process.wait
end
end
