From e0e180aa9d9cac1e427ac23be49aca0c4059f755 Mon Sep 17 00:00:00 2001 From: Kim Alvefur Date: Sat, 15 Jan 2022 09:09:24 +0100 Subject: mod_cron: Allow for a small amount of timer drift If the timer activates a bit early then a task might be just a few seconds short of being allowed to run. This would run such a task rather than wait another hour. The value 0.5% chosen so that a weekly task does not run an entire hour earlier than last time. --- plugins/mod_cron.lua | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'plugins/mod_cron.lua') diff --git a/plugins/mod_cron.lua b/plugins/mod_cron.lua index f18d3a9a..f0c85615 100644 --- a/plugins/mod_cron.lua +++ b/plugins/mod_cron.lua @@ -40,7 +40,7 @@ function module.add_host(host_module) function host_module.unload() active_hosts[host_module.host] = nil; end end -local function should_run(when, last) return not last or last + periods[when] <= os.time() end +local function should_run(when, last) return not last or last + periods[when] * 0.995 <= os.time() end local function run_task(task) local started_at = os.time(); -- cgit v1.2.3
