You can find more details on SystemTimer and how to use it at /articles/system_timer This implementation is not intended to be drop-in replacement to timeout.rb, just a way to wrap sensitive call to system resources. Special care has been taken to interfere as little as possible with other processes that might also rely on SIGALRM, in particular MySQL. As it turn out the timeout library bundled with Ruby 1.8 (MRI) relies on green-threads to perform its magic… so the magic had no chance to happen in this scenario.īased on an original idea by Kurtis Seebaldt, David Vollbracht and Philippe Hanrigou pair programmed an alternative implementation based on system timers (the SIGALRM POSIX signal): This design guarantees proper timeout behavior even when crossing-boundaries and accessing system/external resources. A closer analysis revealed that the native thread in charge of of the web service call was never scheduled, “stucked” on the service call. While deploying Rails application in production our team discovered that some web service call would not timeout way beyond their defined limit, progressively freezing our Mongrel cluster until we restarted the servers. © 2008-2010 David Vollbracht & Philippe Hanrigou James Tucker - Fix for RubyGems 1.6, which will not require "thread" Jesse Storimer - Explicit required_ruby_version = '~> 1.8.7' in gem spec.

You can install the gem on Microsoft Windows, but you will only get a convenience shell wrapping a simple call to timeout.rb under the cover.ĭmytro Shteflyuk : - Changed from using Mutex to Monitor. SystemTimer only works on UNIX platforms (Mac OS X, Linux, Solaris, BSD, …).

# Something that should be interrupted if it takes too much time. This is useful when `timeout.rb`, which, on M.R.I 1.8, relies on green threads, does not work consistently.
System Timer, a timer based on underlying ‘SIGALRM` system timers, is a solution to Ruby processes which hang beyond the time limit when accessing external resources.
