Hi,

I translated the CPP example of a windows service to D.
https://docs.microsoft.com/en-us/windows/desktop/Services/svc-cpp

I wonder how can I integrate a vibe.d http server here:

__gshared HANDLE ghSvcStopEvent = NULL;

VOID SvcInit(DWORD dwArgc, LPTSTR* lpszArgv)
{
    ghSvcStopEvent = CreateEvent(NULL, // default security attributes
            TRUE, // manual reset event
            FALSE, // not signaled
            NULL); // no name

    if (ghSvcStopEvent == NULL)
    {
        ReportSvcStatus(SERVICE_STOPPED, NO_ERROR, 0);
        return;
    }

    ReportSvcStatus(SERVICE_RUNNING, NO_ERROR, 0);

    // TO_DO: Perform work until service stops.
	
    while (1)
    {
        WaitForSingleObject(ghSvcStopEvent, INFINITE);
        ReportSvcStatus(SERVICE_STOPPED, NO_ERROR, 0);
        return;
    }
}

WaitForSingleObject will wait forever until ghSvcStopEvent will be filled
(by extern (Windows) VOID SvcCtrlHandler(DWORD dwCtrl) nothrow).

Do you have any proposal how to integrate vibe.d here?

Kind regards
André

Start vibe in another thread and return from ServiceMain, see https://docs.microsoft.com/en-us/windows/desktop/Services/service-servicemain-function also ideally you should report running state only after vibe initialized, opened sockets and started listening, before that it's not really running.

Thanks a lot. I will try.

I tried to wrap WaitForSingleObject into a Fiber by using command runTask. In theory it should work fine but the service (app) just crash without any information on an empty runTask function.

Also calling listenHTTP crashes the service. Here I am able to catch the Error "eventcore.core static constructor didn't run!?".

I created a github issue with complete source code here https://github.com/vibe-d/vibe-core/issues/105

Kind regards

You don't need to initialize runtime because it's initialized by standard D startup code, but you need to attach threads that are not created by D or static constructors won't be run and only C-level code would work there.

Thank you, I wasn't aware of this. For references, I found this post which explains thread_attachThis. I assume you meant this function.

Kind regards

Today I needed this too, and after some searching I came across this package which works ok for me with vibed:
