Windows support? about final-pm HOT 11 CLOSED

There is no windows support at the moment. None planned either.

from final-pm.

Though that went surprisingly far. Let me check how much would actually need to be done to support Windows.

from final-pm.

Pretty much all that is necessary to get it working is not using unix domain sockets and fixing the ENOENT when starting the daemon.

All tests, besides (for obvious reasons) the unix domain socket test pass on Windows as well.

Thank you for your quick update. I can finally run it on windows, although I still need to comment out the examples related things in cli-args.js

The most important thing of seeking a PM2 alternative is that, all forked processes cannot trigger process.on('exit'), process.on('SIGINT') anymore. I tried with final-pm on Windows, the result is the same. These events have never been triggered.

That's a problem with Windows in general. Not specific to final-pm, PM2, or even node.

Note: Windows does not support sending signals, but Node.js offers some emulation with process.kill(), and subprocess.kill(). Sending signal 0 can be used to test for the existence of a process. Sending SIGINT, SIGTERM, and SIGKILL cause the unconditional termination of the target process.

Maybe I'll add an option to send a message via IPC instead of a signal. But at the end of the day I can't recommend using a windows host for (node.js) applications in production. That is pain without end.

You might be fine just developing on Windows, but even then you'll encounter modules that have lackluster support for Windows all the time. Case in point: The ws[1] module's client doesn't appear to
have support for named pipes on windows, else I'd have implemented that as a replacement for unix domain sockets when I added Windows support.

@stanleyxu2005 What do you mean you have to comment the examples related things in cli-args.js?

I just noticed they're somehow garbled in windows power shell, but nothing really breaking.

from final-pm.

The git repo contains a dir "examples" but when you publish the code to npm, I believe this dir is not shipped, so that when I start final-pm, it cannot find some files from this dir.

exports.example = [
    {
        header: "Example",
    },
    {
        content: {
            options: {
                noTrim: true
            },
            data: [
                { col: "[underline]{Example Config}" },
                { col: "[italic]{final-pm --config sample-config.js start myApp}\n" }
            ].concat(fileToColumns('examples/sample-config.js'))
        }
    },

It's very easy to reproduce.

mkdir test1
cd test1
npm install final-pm
node_modules\.bin\final-pm start all

@laino Thank you for the clarification of signal capture things in Windows. I still hope to find some way to simulate sending CTRL+C to stdin. In short, I create master.js and child.js, and then when I press CTRL+C to stop master.js, child.js is able to trap readline close event. Here is the full version of the story Unitech/pm2#3467

Node under Linux works quite smooth. But for Windows users and development, it has a lot of pain. I need to understand whether this is a Node issue or common problem. If Python does not have the problem, I might need to re-write my whole piece of code in Python or other languages.

from final-pm.

I'm unsure, but this may help.

As for the bug with the examples, I can't seem to be able to reproduce it.

from final-pm.

Oh. Yeah, I expect to have a tiny exe to send ctrl+c to any application, or a node module binds with similar c code. For example there is a deasync node module can force nodejs to run code in sync-manner.

Regarding the bug with the examples, maybe it is because I actually ran yarn add final-pm --production and I have a .yarnclean at my project directory, which might remove examples dir by default. Do you think cli-args.js contains export.examples is good practice?
