The 'singleton' library may have race conditions on init --------------------------------------------------------
Key: JRUBY-5268 URL: http://jira.codehaus.org/browse/JRUBY-5268 Project: JRuby Issue Type: Bug Components: Standard Library Affects Versions: JRuby 1.5.6 Reporter: Charles Oliver Nutter Assignee: Thomas E Enebo Fix For: JRuby 1.6 The 'singleton' library lazily initializes a single object instance once included into a given class. However, it's possible this initialization is not thread-safe, subject to various races. One such issue prompted Nokogiri folks to stop using singleton under JRuby: https://github.com/tenderlove/nokogiri/commit/5eb036e39ea85a8e12eebee11bc5086b0e4ce6e3 My best guess at a glance is that the complexity of lazily initializing a singletonized class or the singleton instance of that class is too complicated and does not consider truly concurrent execution sufficiently well. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.codehaus.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email
