single_running_checker¶ ↑
A simple method that checks the existence of an already running rake tasks (as the PID file and task name) and telling the task is running or not.
Usage¶ ↑
in config/environment.rb:
config.gem "single_running_checker"
and in .rake file:
require "single_running_checker" include SingleRunningChecker
…
task :some_task => :environment do
do_something until task_running?('some_task')
end
task_running?(name, only_check=false) returns true when found pid-file (in tmp/pids) and process command line contains name. If only_check true, method will not create pid-file.
Note on Patches/Pull Requests¶ ↑
-
Fork the project.
-
Make your feature addition or bug fix.
-
Add tests for it. This is important so I don’t break it in a future version unintentionally.
-
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
-
Send me a pull request. Bonus points for topic branches.
