Never get unity logs

[RobinHSanner]

The code:
.withUnityLogger(message =>
{
log.debug(Unity: ${message});
console.log(Unity: ${message});
})
never gets hit. When unity does have a problem the error is always:
{"unityLog":""}

Lately for no apparent reason i'm getting the error that says unity crashed and the log file it says it created is always empty.

The problem can be simulated by using the erroneous: .withBuildOptions({ strict: true }) - should be strictMode.

In unity_invoker.js if I modify the function toArgv with:

    else if (key === 'logFile') {
        argv.push('c:\\temp\\unity.log');
    }

then I get a log. by default the logFile property is set to true and so nothing gets pushed after it but according to https://docs.unity3d.com/Manual/CommandLineArguments.html -logFile needs a filename after it.

Hello @RobinHSanner, thanks for the report!

What version of Unity do you use? I suspect 2017.x since this used to work before.

Yes, -logFile without argument seems counter-intuitive, but this is how you were specifying to Unity to not use a log file and send back the log in real time to stdout. Then we we were watching stdout and writing our own log file in case of problem.

I will check if the behaviour has effectively changed in Unity 2017, try to reproduce and fix the problem (implementing a different behaviour based on the version of Unity) and I'll keep you informed.

Hello again,

I can't reproduce with Unity 5.x, nor with Unity 2017.x.

Also, what's your OS? Compatibility with Windows is mostly untested, and I wouldn't be surprised if this specific point about logfile/stdout has a different behaviour on Windows.

Unity 2017.3.0f3
Windows 10

Okay, must be a Windows-specific problem.

So that's a problem on Windows indeed: https://answers.unity.com/questions/19566/command-line-feedback.html
One of our teammate on Win had the same problem as you.
Unless someone proposes a workaround it'll stay a wontfix, better wait a proper fix from Unity.
