daemon

问题 If I have a Thread object, I can call setDaemon(true) on it to mark that this thread should not prevent application shutdown if all other non-daemon threads have terminated. Is it possible to make this behavior automatically trickle down to all child-threads? I.e. if I have a thread that is marked as a daemon-thread, is there some way to enforce that all threads spawned by this thread are also automatically marked as daemon-threads? 回答1: Is it possible to make this behavior automatically

问题 I am using daemon to wrap my script and has specified logs location into that : Script looks like this : #!/usr/local/bin/ruby require 'rubygems' require 'daemons' Daemons.run_proc( 'script_test', # name of daemon :log_output => true, :output_logfilename => "script-test.log", :logfilename => "script-test.log" ) do exec 'ruby /opt/script-test/script-test.rb' end Problem is my logs are storing in same directory where my script is present. I have to add my logs to different directory such as

问题 I want to create a apache extension for my special protocol wich listens on the same port as apache but on a specific directory or file like php. I need this to power my game with a custom server but not with php. I cant listen on a different port or different server. I dont want to create a php file or something similar. i need a complete executable program where i can dynamically allocate memory etc. the program is completly outside of the apache server, but the apache 'passes-through'

问题 Using a JettyRun task, it's easy to debug. You can merely add something like -Xdebug -Xrunjdwp:transport=dt_socket,address=12233,server=y,suspend=n to your GRADLE_OPTS and hook up to the gradle process itself. However, if you run a JettyRun task with daemon = true, this doesn't work. Example of one such task: task jettyRunDaemon (type: JettyRun) { contextPath = '/' classpath = sourceSets.test.runtimeClasspath webAppSourceDirectory = file('src/test/webapp') daemon = true } I've tried some

问题 I have supervisor for managing queue notifications as suggested in the laravel documentation . I have configured the supervisor as per the documentation and here is my configuration file.

问题 I'm trying to code a daemon in Unix. I understand the part how to make a daemon up and running . Now I want the daemon to respond when I type commands in the shell if they are targeted to the daemon. For example: Let us assume the daemon name is "mydaemon" In terminal 1 I type mydaemon xxx. In terminal 2 I type mydaemon yyy. "mydaemon" should be able to receive the argument "xxx" and "yyy". 回答1: If I interpret your question correctly, then you have to do this as an application-level construct

问题 I need a reasonable supply of high-quality random data for an application I'm writing. Linux provides the /dev/random file for this purpose which is ideal; however, because my server is a single-service virtual machine, it has very limited sources of entropy, meaning /dev/random quickly becomes exhausted. I've noticed that if I read from /dev/random, I will only get 16 or so random bytes before the device blocks while it waits for more entropy: [duke@poopz ~]# hexdump /dev/random 0000000 f4d3

问题 I'm a noob to objective c and I have a daemon code that runs as root (system-wide application) and communicates with a server. Every once in a while, the server will command that root app to fire up an additional application that runs within the logged on user context (without interrupting the user - silently). I have the user context application written as well. What I'm lacking is the understanding on how my root daemon can launch the user context application. How can my daemon fire it up

问题 Could someone explain me in two words, what is daemon and what use of them in php? I, know that this is a process, which is runing all the time. But i can't understand what use of it in php app? Can someone please give examples of use? Can i use daemon to lessen memory usage of my app? As i understand, daemon can hold data and give it on request, so basically i can store most usable data there, to avoid getting it from mysql for each visitor? Or i'm totally wrong? :) Thanks ;) 回答1: Could
