jobs

问题 I am testing the queue functions in Laravel 5.1. I can make jobs queue up in my db table, called jobs, and I can get them to run successfully. I also created a queue failure table called failed_jobs. To test it, inside the jobs table I manipulate the payload data to make it fail then I run the queue worker daemon like so, so it will put the job in the failed_jobs table after one failed attempt: php artisan queue:work --daemon --tries=1 --queue=myqueue When the job fails it is immediately put

问题 I am currently developing a RubyGem that provides an executable. The executable keeps track of the state of some log files using the FSSM gem. This executable should get started, do something in background, and get stopped later on. For example: $ my_executable start # do something different... $ my_executable stop I would first start a new process, that does the file watching stuff, inside the start method. But I don't know how to address this process for stopping it. What's the best way to

问题 I want to create a job which deletes records from a database after a period of time has passed.

How can I accomplish this? 回答1: you should create a job in SQL below is a sample T-SQL for create a job via SQL agent

问题 Using Kue, how do I schedule a job to be executed once every Thursday? The Kue readme mentions that I can delay a Job, but what about repeatedly executing the Job at a specific time?

What I want is to process a Job once anytime on Thursday, but only once. 回答1: I had a similar question and I basically came up with the following. If anyone else has a different solution I would love to see some other ideas. var jobQueue = kue

问题 Just switched from bash to zsh. In bash, background tasks continue running when the shell exits. For example here, dolphin continues running after the exit : $ dolphin . ^Z [1]+ Stopped dolphin . $ bg [1]+ dolphin . & $ exit This is what I want as the default behavior. In contrast, zsh's behavior is to warn about running jobs on exit , then close them if you exit again. For example here, dolphin is closed when the second exit -command actually exits the shell: % dolphin . ^Z zsh: suspended

问题 I am working on making a scheduler, just like Windows Scheduler using Quartz.Net. In Windows Scheduler, there is an option to stop a task from running if it takes more than the specified time.
