Write a daemon on Windows (1) starts withRecently, due to the need for work, to write a daemon, the main thing is to be in the process of hanging up the daemon to start again. This function is relatively simple to say, but I wrote a lot of things that look bad now, so I want to write a little more pleasing to the eye.

Recently, due to work requirements, we need to write a daemon process, which should be started when the daemon is suspended. This function is relatively simple to say
Friends of the company Tomcat running under the Windows platform, its mention Tomcat is not very stable, always hanging, there is no good way. One of the suggestions given to him was to open a Tomcat daemon. Because Windows does not look like Linux (Linux platform commands, all kinds of syntax, all kinds of convenience), win platform under the bat feel weak and d
Write a daemon on Windows (7) Catch exceptions and generate dumpNo one can guarantee that their code is not a bug. Once out of the bug, it is best to crash, so quickly can be found, if not crash, but the business process is wrong, it is troublesome, it may be a long time before being discovered. So, if it crashes, how do you find out what's wrong? The classmate who wrote the

Write a daemon on Windows (4) Log the restThis time I said everything else related to the journal.First, VaformatC + + log interfaces usually have two forms: stream input form, printf form.I use the printf format because the stream input is not well controlled.printf form requires the log interface to support variable length parameters, I do not directly in the log implementation class support variable leng
Write a daemon on Windows (8) Get the process pathTo protect a process, you need to know that the process is not there. We assume that there will only be one instance of the process to be guarded (and this is most of the case).I'm going to walk through all the processes on the system, and then determine if the process exists by determining whether their path is consistent with the process being guarded.Trav

To guard a process, you must first know that the process is absent. We assume that only one instance exists for the process to be guarded (this is also the case in most cases ).

Development Department of a core program will always be down, and then need to go manually, and the security level of this service is very high, only I can operate, make my night old can't sleep, last night really can't stand, think of the shell daemon process previously written under HP-UX, This back to a Windows bat version of the daemon, then the evening thoug
Write a daemon on Windows (3) handle managementProgramming in Windows, dealing with handle is a common occurrence. In order to prevent forgetting CloseHandle, I use the do-while-false technique:void f () { = NULL; Do { while (false); if (h) { CloseHandle (h); = NULL;} }Handle more, you have to write several lengths of the

The last few days overtime plus crazy off, every night can not sleep. One of the core programs in the development department is that it's always going to go down on its own, and then it needs to be done by hand, and the service is so secure that I can do it, and I can't sleep at
Brief Introduction
Project using Python to write a monitoring program, every 5 seconds to monitor the directory, found the file immediately FTP synchronization to another server. Business requires high timeliness and high availability. To beware of a program crash, write a daemon program that monitors whether the program crashes and restarts.
Here are two ways to implement this.
The first kind of monitoring process PID mode demo.py 10 seconds to s
In the previous Windows Bat Curl implementation Tomcat Daemon, according to the Bat Deamon program written a few years ago, implemented the function of Tomcat Deamon, in the end also mentioned Python to achieve, to be more powerful and more intelligent. Here's a more powerful Tomcat daemon based on Python implementations. Features currently implemented:
