	DurationLogRotate   = 1 * 60 * 60 * 24
	DurationAppBackup   = 1 * 60 * 60 * 24
)

启动时执行的轮询任务用于随时刷新持久化数据持久化数据用于恢复

var CronJobMap map[cron.EntryID]*Cron

CronJobMap 保存所有的定时任务没必要使用syncmap 采用内部加锁的方式保证数据安全性

Functions ¶

AddJobAPPCheck app服务定时检查

func AddJobAPPDumps ¶

func AddJobAPPDumps()

AddJobAPPDumps 从缓存同步配置到mongo 用于同步配置参数和端口变量

func AddJobAPPSync ¶

func AddJobAPPSync()

AddJobAPPSync app配置文件同步同步配置文件到配置文件目录

func AddJobBackup ¶

func AddJobBackup()

AddJobBackup 定时备份App 使用cron任务代替此任务仅作删除old备份使用

func AddJobDBPersist ¶

func AddJobDBPersist()

AddJobDBPersist 数据库内容持久化

func AddJobDBSaver ¶

func AddJobDBSaver()

AddJobDBSaver 数据库刷新

func AddJobLogRotate ¶

func AddJobLogRotate()

AddJobLogRotate 日志裁剪任务对log目录下的所有日志绕接

func AddJobOctopusMetaSync ¶ added in v1.0.7

func AddJobOctopusMetaSync()

AddJobOctopusMetaSync 重载整个octopus目录

func AddTicker ¶

func AddTicker(t int, taskName, des string, f func())

func InitBackgroundJobs ¶

func InitBackgroundJobs()

func InitCronJobs ¶ added in v1.1.1

func InitCronJobs()

func InsureTickerExit ¶

func InsureTickerExit()

InsureTickerExit 确保程序退出时关闭协程

Types ¶

type Cron ¶

type Cron struct {
	CronID       cron.EntryID `json:"cron_id"`
	CronName     string       `json:"cron_name"`
	CreateTime   time.Time    `json:"create_time"`
	Start        time.Time    `json:"start"`
	ExecuteTimes int          `json:"execute_times"`
	Status       string       `json:"status"`
	Finish       bool         `json:"finish"`
	IsSaved      bool         `json:"is_saved"` // 持久化数据库
}

type CronManager ¶

type CronManager struct {
	CreateTime string
	// contains filtered or unexported fields
}

CronManager cron内部实现基于cronV3

func InitCronManager ¶

func InitCronManager() CronManager

InitCronManager 创建一个cron实例

func (*CronManager) AddTask ¶

func (c *CronManager) AddTask(spec, name string, f func()) (cronID cron.EntryID, err error)

AddTask 添加cron任务添加任务仅是存储并不会立刻启动

func (*CronManager) AllTask ¶

func (c *CronManager) AllTask() ([]cron.Entry, error)

AllTask 返回cron内部的全部任务

func (*CronManager) Check ¶

func (c *CronManager) Check() bool

Check 检查cron的实例是否存在

func (*CronManager) DelTask ¶

func (c *CronManager) DelTask(id cron.EntryID) error

DelTask 直接删除定时任务由cron保证从内存中去除

func (*CronManager) StartTask ¶

func (c *CronManager) StartTask(id cron.EntryID) error

StartTask 启动cron

func (*CronManager) StopTask ¶

func (c *CronManager) StopTask(id cron.EntryID) error

StopTask 停止cron
