Changelog¶

1.1.12 Sun Feb 9 04:27:38 PST 2014 * GEARMAN_SERVERS environmental variable for libgearman to pick up servers to communicate with. This means that any driver now linked with libgearman will be able to handle multiple servers. * Add INFO level messages for queue creation.

1.1.10 Mon Sep 16 04:20:13 CDT 2013 * Added gearman_job_use_client() * Improve compile time. * Fix for NOOP failure (bad worker causes early exit of loop). * Fix for postgres (use INFORMATION_SCHEMA). * Added gearman_client_has_active_tasks() so that you can see if a client has active tasks that it is working on.

1.1.7 Mon May 6 06:46:20 EDT 2013 * Cleanup of error codes returned by gearmand. * gearmand will now set its port from the env variable GEARMAND_PORT. * Fix issue where identifier might not be set correctly on reconnect.
