Elysia Cron 6.x-1.2

Extended cron support with crontab-like scheduling (you can run some cron hooks every day at a specified hour, other only monthly and so on...) and other features: * crontab-like scheduling configuration of each job. * grouping of jobs in channels (parallel lines of execution). * you can disable all jobs, an entire channel or a single job via configuration. * force execution of a single cron job on demand * change the priority/order of job execution * time statistics of each job and of the whole channel. * modules can define extra cron tasks, each one with own default cron-rules (site administrators can override them by configuration). * administrators can define custom jobs (call to functions with parameters) * protection from external cron calling by cron_key or allowed host list. * ensure all shutdown hook functions launched by cron jobs are launched inside cron protection (ex: search_cron() will launch search_update_totals() in a shutdown hook).Example of a cron scriptNote: this is only a way to configure scheduling, there is also a simpler guided configuration.# Search indexing every 2 hours (i'm setting this as the job description)0 */2 * * * search_cron# I'll check for module status only on sunday nights# (and this is will not be the job description, see the empty line below)0 2 * * 0 update_status_cron# Trackback ping process every 15min and on a channel called "net"*/15 * * * * ctx:net trackback_cron# Disable node_cron (i must set the cron rule even if disabled)- */15 * * * * node_cron# Launch function send_summary_mail('test@test.com', false); every night# And set its description to "Send daily summary"# Send daily summary0 1 * * *  send_summary_mail('test@test.com', false);Example of a module defining its cron jobs// Assume your module needs 2 cron tasks: one executed every hour (process_queue)// and one executed once a day (send_summary_mail).function module_cronapi($op, $job = NULL) {  switch ($op) {    case 'list':      return array(        'module_process_queue' => 'Process queue of new data',        'module_send_summary_mail' => 'Send summary of data processed'      );    case 'rule':      if ($job == 'module_process_queue') return '0 * * * *';      else return '0 1 * * *';    case 'execute':      if ($job == 'module_process_queue') {        ... do the job ...      }      // Just for example, module_send_summary_mail is on a separate      // function (see below)  }}function module_send_summary_mail() {  ... do the job ...}More infoREADME.txt (Full overview)INSTALL.txt (Installation instructions)External documentation:Installation guide, usage instructions and examples @ www.cmswiki.net (ITALIAN Language)CreditsElysia cron is a part of the Elysia Community Platform project (but could be used stand alone with no limitation).Developing is sponsored by Void Labs s.n.c (http://www.void.it)
