javan / whenever

This article suggests we need to explicitly flush logs. Perhaps the snippet of code in the article could be generated by whenever?

https://earthcode.com/blog/2009/05/rails_script_runner_logging_cron.html

when i use every 2.hours i get 0,2,4,6,8...
but i need 2 crons with differen tart time.

cron 1 0,2,4,6,8...
cron 2 1,3,5,7,9...

a range option were nice:

every 2.hours, :range => 1..23

Haven't got time to fork and fix this myself atm, but nice priority for jobs a definite 'nice-to-have' ;)

I would submit a patch to chronic, but it seems like mojombo isn't really updating chronic anymore. It looks like evaryont/chronic has been updated much more recently and doesn't have the dependency on hoe. Not sure if you want to change the chronic dependency or try to get mojombo to push a new version of chronic, but it would be nice to not have the extra dependency for whenever, especially when bundling it.

I used the option :cron_log, which did work

I use ruby stored in /opt/ruby-1.9.x-pXXX/ and I would like to set custom path to "ruby" (for script/runner) and "rake" commands in schedule.rb.

I have a Rails app running in two environments to serve two countries.

The first whenever call setup most of the tasks (country independent), the second and third run the few that must be run for both countries (environments).

whenever --update-crontab myapp --set environment=staging_au && whenever --update-crontab myapp_au --set environment=staging_au --load-file config/schedule_both_countries.rb && whenever --update-crontab myapp_nz --set environment=staging_nz --load-file config/schedule_both_countries.rb

It will work the first time, but each time you update the cronjob after the file will get corrupted.
Seems like naming them au_myapp and nz_myapp is enough to solve it.

whenever --update-crontab myapp --set environment=staging_au && whenever --update-crontab au_myapp --set environment=staging_au --load-file config/schedule_both_countries.rb && whenever --update-crontab nz_myapp --set environment=staging_nz --load-file config/schedule_both_countries.rb

Non of existing(rake, command, runner) fit well for that:

script/delayed_job start

I've it in my repo.

Adding a config directory and running wheneverize . generates schedule.rb correctly, but then running whenever raises an undefined method 'blank?' for nil:NilClass error.

I've run into a rather bizarre problem while using whenever with rvm.

If I use and rvm ruby then whenever will refuse to run my cron jobs. It spits out a message saying that Rails 2.3.5 is not installed. Obviously this is wrong. If I remove rvm from my path and regenerate the job then it begins to work again. The only way that I have been able to have both working at the same time is to explicitly set path inside schedule.rb minus rvm.

env 'PATH', '/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/local/nginx/sbin:/usr/bin:/usr/sbin:'
every 2.minutes do
runner "MyClass.a_method" end

whenever will then work as it is executing the command from the system (default) ruby in /usr/bin and not any of my usual rvm rubies. Not good. It also introduces unwanted issues for deployment. Has anyone else run into this problem? I've tried all manner of configurations in schedule.rb to get whenever to behave but unless I remove rvm from my path (at least from whenever's perspective) then if I check mail I get an error like this:

Subject: Cron <i0n@Zico> /Users/i0n/Sites/commval/script/runner -e development "MyClass.a_method"

Missing the Rails 2.3.5 gem. Please gem install -v=2.3.5 rails, update your RAILS_GEM_VERSION setting in config/environment.rb for the Rails version you do have installed, or comment out RAILS_GEM_VERSION to use the latest version installed.

Hello

I updated whenever from 0.4.1 to 0.4.2 and the whenever command line executable stopped working.

It cannot print anything, even "whenever -v" returned nothing.

My config/schedule.rb file looks like next

set :path, '/var/rails/app1/current'
set :environment, :production
set :output, {:standard => '/var/rails/app1/shared/log/cron.log', :error => '/var/rails/app1/shared/log/cron_error.log' }
every 1.day, :at => '10:30pm' do
  rake "some:rake:task"
end
every 1.day, :at => '11:30pm' do
  rake "other:rake:task"
end

I'm using Ruby Enterprise Edition 1.8.7 (2009-12-24 patchlevel 248) over Ubuntu 8.04.4 and my gems list is:

actionmailer (2.3.5, 2.3.2)

Please don't hesitate to ask for more information about my environment configuration.

Life on the bleeding edge! Whenever doesn't seem to like the shiny new Rails 3 beta at all.

If you add whenever to a Rails 3 apps Gemfile (through passenger) I get this error:
undefined method `load_tasks' for nil:NilClass

I forked the whenever repo and had a bit of a look.
If I commented out

begin
load 'Rakefile' rescue LoadError
nil end

from lib/whenever.rb then the gem will load in Rails 3. I'm not 100% what this bit of code is trying to do though, it mentions trying to load the Rails projects Rake tasks? It's trying to list available rake tasks for inclusion in cron jobs?

Anyway, after that I had to change one of the require paths to be able to run the test suite, returned 14 or so errors mainly around Chronic::RepeaterTime::Tick

Happy to help with upgrading to work with Rails 3, would be cool to get a little insider info on how things are set up!
