crontab定時(shí)任務(wù)組件，秒級(jí)任務(wù)會(huì)重復(fù)執(zhí)行
bug描述
定時(shí)任務(wù)組件,1s執(zhí)行一次的任務(wù)經(jīng)常會(huì)重復(fù)執(zhí)行
程序代碼
new \Workerman\Crontab\Crontab('*/1 * * * * *', function () {
$time = time();
$timeLock = "task_lock:" . $time;
if (Redis::exists($timeLock)) {
echo "當(dāng)前秒存在任務(wù)";
return;
}
Redis::set($timeLock, 1);
echo date('Y-m-d H:i:s') . PHP_EOL;
});期待的結(jié)果及實(shí)際結(jié)果
這里是輸出

系統(tǒng)環(huán)境及workerman/webman等具體版本
mac和linux出現(xiàn)了,workerman/crontab版本v1.0.4
3個(gè)回答
打賞
如果你開了2個(gè)進(jìn)程，每個(gè)進(jìn)程定時(shí)執(zhí)行一次可能會(huì)出現(xiàn)這種情況

webman進(jìn)程數(shù)在 config/server.php 里用count設(shè)置。
自定義進(jìn)程在config/process.php里用count參數(shù)設(shè)置。 -

process.php設(shè)置是這樣的,沒有設(shè)置count<?php

如果一個(gè)進(jìn)程 你加redis 就是毫無意義 ，本來就是 一秒執(zhí)行一次
