A library implementing PEP 3143 for creating well-behaved Unix daemon processes

This library implements the well-behaved daemon specification of PEP 3143, "Standard daemon process library". A well-behaved Unix daemon process is tricky to get right, but the required steps are much the same for every daemon program. A DaemonContext instance holds the behaviour and configured process environment for the program; use the instance as a context manager to enter a daemon state.

Nice framework for building daemons in python

Service Wrapper,可以用于包装bat成为一个Windows Service

YAJSW is a java centric implementation of the java service wrapper by tanuki (JSW). It aims at being mostly configuration compliant with the original. It should therefore be easy to switch from JSW to YAJSW. JSW is a wonderful software I have been using for some time in production. So why yet another framework ? The main reason is that I need a better integration within my java job scheduling framework (rzomx) As of the next version the license of JSW will change making it impossible for me to use it in rzomx I may need win64 support, which is currently not available or not free for JSW.

Yet Another Java Service Wrapper YAJSW allows one to install any application as windows service or posix daemon and to monitor it.

"以下「プロトコル処理」と「メッセージ処理」を分けて扱っているが、この差が顕著に出るのは全文検索エンジンや非同期ジョブサーバーなど、小さなメッセージで重い処理をするタイプ。ストリーム指向のプロトコルの場合は「プロトコル処理」を「ストリーム処理」に置き換えるといいかもしれない。"
